According to Korean media reports, after 24 years of continuous expansion, emart (e-mart), a large discount supermarket owned by Shinsegae Group of South Korea, began to streamline its business, and recently said that it would completely withdraw from China by the end of this year.

Emart pointed out that due to the poor performance, the company has decided to close all the six remaining stores in the China market.

After years of huge losses, e-mart finally came to an end.

It is reported that emart has been losing money in China market for many years. As early as 2011, the loss of emart in China market has exceeded 100 billion won (about 88 million US dollars). In the next four years (2012-2016), due to the rising operating costs and weak market demand, its accumulated losses reached 150 billion won (about 133 million US dollars), reaching the point of "unable to survive".

According to public information, emart first entered the China market in February 1997, and opened the first "e-mart" supermarket in Shanghai. Later, it opened more stores with Jiangsu, Zhejiang, Tianjin and Beijing as the centers. At that time, it was announced that it would open 1,000 stores in China. By 2010, its total number of stores in China reached 27.

However, at this point, e-mart supermarkets can no longer open.

In 2011, the development of emart in China market suffered from "Waterloo", and 12 stores were closed at one go. By 2014, the number of its China stores has been reduced to 10; There were only 7 in November 2016; In March this year, it was announced that there were only six stores in the Old Ximen District of Shanghai. Today, the last six companies can’t keep it, and they will be evacuated one after another this year.

At present, there are 7 stores that can be selected when logging in to official website, China, e-mart, including Shanghai Laoximen Store, but the whole website is in a state of almost no maintenance. No matter which store you choose, the page display will be the same. Except for the two channels of "Poster Commodities" and "Store Promotion Commodities", the two channels of "New Commodities" and "e-mart Special Sale" are completely blank.

(Some channels in official website, e-mart are completely blank.)

In addition, the focus map on the homepage of the website also shows the publicity page of the 20th Anniversary Celebration (April 19th to May 2nd). Because this year is the 20th anniversary of the opening of Quyang Store in e-mart. However, this time seems a bit bleak, and the 20th anniversary has also become the "drama ending day".

Internal and external factors doomed this tragedy?

Looking back on the development of emart in China market, it seems that both internal and external factors doomed the closure of e-mart supermarket.

"Korea Economic Daily" concluded: e-mart Supermarket has never been successfully established, one of the important reasons is the poor geographical location of the store, which is attributed to its late entry into China. At the same time, compared with other retailers, e-mart’s prices and goods are not competitive. This is the failure of its own business strategy.

In addition, it is an indisputable fact that the format of China’s hypermarkets has entered a "downhill" several years ago. In recent years, the adjustment of store closing and transformation has been the main theme of this industry. In addition to the frequent news of store closing by local merchants in China, foreign giants such as Carrefour and Wal-Mart are also constantly "slimming down", and Lotte Mart, a Korean compatriot of emart, has also completely withdrawn from China this year.

An insider pointed out that, in fact, from the perspective of the whole retail industry, the market is increasing, and the situation of each format and each enterprise is different. "Those enterprises with high level of refinement, strong innovation ability and rapid transformation and upgrading will get out of the predicament faster, and vice versa."

Obviously, for so many years, emart seems to have never found the crux of its difficulties in the China market. Or, it has found the crux, but it has been unable to save it.

However, despite repeated defeats in China, in recent years, emart’s expansion in the whole overseas market is still very positive. When it announced its complete withdrawal from the China market, its officials mentioned that the company would shift its focus to fast-growing markets such as Viet Nam and Mongolia.

Previous media reports have pointed out that emart began to export to the Philippines in January this year, opened up the Japanese market in March, and entered the UK in April. Since then, the company plans to enter Thailand, Uzbekistan, Russia, the Netherlands and other places one after another. The goal is to earn more than 100 billion won (about 86.5 million US dollars) in overseas markets by next year.

It is not difficult to see that finding a way out in other countries may be an important measure for emart to make up for the market failure in China.

Change your skin and stay in China

It is worth noting that in recent years, under the background that all kinds of overseas supermarkets have entered China through e-commerce channels, emart can’t give up this fat piece of China market after all. Although all offline stores (e-mart Supermarket) will be closed soon, its online business (except official website, China) is still going on, but it has changed into a cross-border e-commerce mode.

It is understood that in 2015, when the offline business was "gone", emart caught up with the enthusiasm of cross-border e-commerce and chose another way to enter China: in July 2015, it joined hands with Netease Koala, and in October 2015, it settled in Tmall International to open the "emart official overseas flagship store".

At present, its business in Tmall International and Netease Koala is operating normally. When we open the official overseas flagship store of Tmall International emart, we can see that it provides goods to China consumers in two cross-border e-commerce modes: "overseas direct supply" (that is, overseas direct mail) and "bonded warehouse delivery", covering nine categories, including personal care, food and beverage, skin care and beauty, household daily use, kitchen appliances and maternal and child products. In Netease koala search "emart", you can find 59 products, all of which are self-operated by Netease koala.

According to previous media reports, Cui Yu, vice president of emart’s parent company, New World Group, publicly said in 2015: "We have a hard time in the offline market in China, but the development possibility in the online market in China is growing."

He pointed out that entering the e-commerce market in China is the latest move of emart to adjust its global asset portfolio, and said that "Korean offline consumers+global online consumers" will become the new strategic direction of global layout of emart in the future.

In fact, after staying in the China market through cross-border e-commerce, emart did taste some sweetness.

In double 11 in 2015, emart, who just settled in Tmall, was ranked 13th in the TOP20 list of pre-sales of Tmall international stores with a total amount of 8,157,740 yuan. But also take this opportunity to launch a number of self-owned brands in double 11.

In Tmall International, emart’s official overseas flagship store, as a representative business of "Korea Pavilion", has gained a lot of exposure opportunities. It is not difficult to find that the sales of its products are relatively hot by opening the product page of its store — — The total sales of the five most popular products are 120,000+,70,000+,60,000+,50,000+and 30,000+,and the sales of other products are also higher among peers. In Netease koala, many emart foods and daily necessities are also among the popular products.

In addition, at the Tmall International Global Merchants Conference held on the 18th of this month, emart also entered the list of "Billion Dollar Clubs" officially announced by Tmall International (that is, merchants whose sales exceeded 100 million dollars), and cooperated with Chemist Warehouse, Costco, Macy’ S, Matsumoto Kiyoshi, Sainsbury’ S, Metro and others stood in the first camp together.

However, in recent years, few overseas supermarkets have really had the last laugh. Emart’s Korean compatriot LOTTE’s "despondent" withdrawal from Tmall in March this year is also a lesson from the past.

A senior practitioner once bluntly told Billion Power Network: "Few overseas businesses can deeply understand Ali’s complex ecosystem, and they don’t understand the operation logic of China e-commerce. A large number of enterprises are coming in, and the platform resources are not enough. In the end, it is inevitable to grasp the big and put the small. Many overseas merchants come to Tmall and I am afraid they will run with them in the end. "

Obviously, emart, who changed into a cross-border e-commerce bag and stayed in China, still faces many strong enemies, and the future development path is full of uncertainties. Whether this transformation can finally be achieved still needs to wait and see.

　　　　　　 CCTV News:During the epidemic period, cases of illegal hunting and sale of wild animals still occurred, and law enforcement agencies in various places severely cracked down on the crime of headwind and severely punished them according to law.

　　　　　　 At 5: 00 pm on January 31, when the police of Jiangchuan District Forest Public Security Bureau in Yuxi City, Yunnan Province inspected the jurisdiction, they found a villager carrying hunting tools, and birds chirped from time to time.

　　　　　　 Stopped by the police, the man put down his tools, bird cages and other items, saying that he was here to help people with Sanqi. When he was idle during the Spring Festival, he went up the mountain to hunt birds to eat.

　　　　　　 From the personal belongings of the suspected man, the police seized six tools for illegal hunting, two white-cheeked noises used as bait, a whistle, and 20 thrush illegally hunted, of which 16 were dead. The police immediately brought Xiong back to the Jiangchuan District Forest Public Security Bureau for further processing.

　　　　　　 In the law enforcement case handling center, Xiong confessed that he and his workers would hunt some wild animals from time to time to improve their lives when they were protecting Sanqi. In order to cut off the epidemic source at the first time and severely crack down on illegal hunting of wild animals, the forest public security organs at Yuxi City and Jiangchuan District immediately dispatched police to the area of Jiuxi Town in Jiangchuan District overnight to conduct surprise inspections on the dormitories and surrounding areas.

　　　　　　 On that night, 5 live wild animals, 1 live partridge, 1 live quail and 1 live yellow-butted snipe were seized, 16 catching tools, 11 iron clips, 1 whistle and 3 slingshots were seized, and 4 people involved were arrested. At present, the case is being further processed.

　　　　　　 In fact, cases like this are not uncommon. In the past few days, the Forestry Bureau of Tujia Autonomous County along the river in Guizhou Province has launched a special law enforcement campaign to crack down on wildlife trafficking. A total of 7 comprehensive farmers’ markets and more than 30 restaurants have been investigated, and 4 wild porcupines, 27 pheasants, 2 rabbits and 11 wild goats have been collected on the spot.

　　　　　　 On February 4th, Xizhu Police Station of Yixing City Public Security Bureau in Jiangsu Province successfully arrested Wang, a suspect suspected of illegal hunting. Through further search, five squirrels and ten Yellow weasel were found dead in the refrigerator of his home, as well as a large number of hunting equipment. After the trial, Wang confessed that since July 2019, more than 20 squirrels and 40 Yellow weasel were illegally hunted and sold in the form of hunting clips.

　　　　　　 What is actually hidden behind a case is the greedy demand for illegal interests.

　　　　　　 On November 7, 2019, security personnel at Guang ‘an Railway Station in Sichuan found a large number of dead wild birds in the suitcases of four passengers, including Lu Moguang. After checking and counting by the police of Guang ‘an Forest Public Security Bureau, 2418 dead wild birds and some hunting tools such as electronic bird traps and bird nets were found in the suspect’s suitcase. After the trial, four suspects confessed to using electronic bird traps and bird nets to hunt wild birds near Fenshuiling Village, shiya town, Yuechi County, Guang ‘an City, and two other suspects. Guang’ an Forest Public Security Bureau quickly organized the police of the Municipal Bureau, Qianfeng District and Yuechi County Forest Public Security Bureau to rush to the scene to arrest. The police investigating the case arrested the suspects Lu Mouliang and Yang Mouyou in Fenshuiling Village, shiya town, Yuechi County, and found seven greenhouses with live wild birds and two refrigerators with dead wild birds. After counting, there were more than 11,000 live wild birds and more than 2,200 dead wild birds.

　　　　　　 Guang ‘an Forest Public Security Bureau immediately set up a "11.7" extra-large illegal hunting case task force to carry out investigation work. After investigation, from mid-August, 2019, the suspects Lu Mouliang and Wu Moufu discussed bird catching to make money, and agreed that Lu Mouliang would be responsible for selecting bird catching places, renting houses, personnel round-trip fares, transportation, bird nets and other preparatory work and sales work. Wu Moufu was responsible for organizing bird catchers. For the birds caught by the bird catcher found by Wu Moufu, Lu Mouliang bought them at the price of live birds 0.8 yuan/bird and dead birds 0.6 yuan/bird, and Wu Moufu paid a commission of 0.2 yuan/bird. In mid-September, 2019, Wu Moufu organized Lu Moguang, Lu Moneng and others to illegally catch birds from congjiang county to Guang ‘an. Subsequently, Lu Mouliang’s cousin Lu Moxi also joined the illegal bird catching. After review, during the period from September 21 to November 6, 2019, criminal suspects illegally hunted more than 110,000 wild birds, mainly sparrows. The criminal suspects transported the hunted wild birds to Qingyuan, Foshan and other places in Guangdong for sale at a price ranging from 1.1 to 3 yuan by means of passenger car consignment, and made an illegal profit of more than 150,000 yuan.

　　　　　　 Recently, with the approval of the procuratorate, 10 suspects suspected of illegal hunting were arrested according to law.

　　　　　　 Cao Mingde, a professor at the School of Civil and Commercial Economics of China University of Political Science and Law, said: "In fact, illegal hunting and illegal trading of wild animals have been repeatedly prohibited for a long time, and an industrial chain has been formed, including illegal hunting, sales and purchase, as well as transportation, carrying, sending and utilization, including domestication and breeding. Then the reasons are various and the demand comes from consumers. Where there is demand, there is a market. "

What are the most noteworthy models at the end of the year? The newly listed Geely Galaxy Starship 7 EM-i should be ranked first. The new car is priced at 103,800-136,800 yuan, and there is a limited-time discount of 4,000 yuan. The price is only 99,800 yuan. So will this new car of Geely Galaxy work?

For most people, it is only the beginning to mention cars from 4S shops, and the cost of car maintenance in the later period is the big deal. So what I said today can help us save some money in the future. Let’s take a good look at it.

Let’s take a look at the appearance of Roewe D7 first. The front style of Roewe D7 looks very angular and stylish. Headlights are very dynamic and lively, a little more exercise. The car is equipped with LED daytime running lights, automatic opening and closing, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4890 mm * 1872 mm * 1510 mm. The car adopts clean and refreshing lines, and the side wall looks very spiritual. With large-sized thick-walled tires, the overall visual effect is very concise. In terms of the rear end, the rear end looks avant-garde and the taillights look very cold and very young and fashionable.

In terms of interior, Roewe D7 interior looks very mellow, and the overall design atmosphere is still in place. The car looks very good outside the steering wheel, and it is equipped with functions such as manual steering wheel up and down+front and rear adjustment, which makes people love it. Take a look at the central control, and with the 12.3-inch touch-sensitive LCD central control screen, the interior design is quite layered and cute. The interior feels good, let’s take a look at the dashboard and seats. The car is equipped with a fashionable dashboard, which is very eye-catching. The car uses a mix of leather/suede seats, equipped with functions such as seat electric adjustment and seat proportion down, and the overall comfort and wrapping are not bad.

Roewe D7 matching gearbox, the acceleration time of 100 kilometers is 7.3s, and the power is completely OK for daily use.

The car is equipped with driving mode selection, remote control key, interior ambient light, traction control (ASR/TCS, etc.), Bluetooth /WIFI connection and other configurations, and the configuration performance is passable and basically satisfactory.

Do you have the urge to buy a car after reading the whole article? Let me make a summary. Such a car with the right price is enough to meet the daily practical needs, and it doesn’t take much thought to maintain it at ordinary times, and the cost performance is good.

　　With the deepening of the concept of environmental protection, green travel has become a new trend of modern urban life. In this context, the Roewe brand under SAIC followed the trend of the times and launched the Roewe D7 DMH, a hybrid car with high cost performance. With its excellent performance, excellent endurance and comfortable driving experience, this model has quickly become the new favorite of the market and led the new trend of green travel.

　　As a hybrid car, Roewe D7 DMH’s biggest highlight lies in its advanced power system and excellent energy efficiency performance. The car is equipped with the industry’s first powertrain brain CPIU, which efficiently integrates core components such as motor, engine and battery, and realizes the maximum utilization of energy. At the same time, the perfect match between the dual-motor hybrid strategy of DMH system and the 1.5L hybrid special machine makes the engine run in the best working condition, greatly reducing fuel consumption and emissions. In the endurance limit challenge, Roewe D7 DMH ran 1704 kilometers with a tank of oil, which fully proved its excellent endurance.

　　Under the background of crazy involution in the current automobile market, Roewe D7 DMH stands out with its high cost performance and excellent performance. It not only meets consumers’ demand for green travel, but also gives consumers real preferential prices. This market positioning undoubtedly makes Roewe D7 DMH an ideal choice for consumers.

　　As a cost-effective hybrid car, Roewe D7 DMH has successfully led the new trend of green travel with its excellent performance, excellent endurance and comfortable driving experience. In the future, Roewe D7 DMH will continue to maintain its leading position in the market competition, bringing more surprises and satisfaction to consumers.

　　CCTV News:Shield machine is the heavy weapon of the country, and now it is being used in more and more projects. Because the shield machine is driving underground, the shield driver can’t see the direction and needs to rely on the data of the surveyor to operate, which requires very high measurement accuracy. And surveyors can’t see the underground situation, so shield survey is also called the most difficult survey work.

　　During this "May 1" holiday, the first domestic 16-meter super-large diameter slurry balance shield machine "Jinghua" was running 24 hours a day in the 50-meter underground west line tunnel of Beijing East Sixth Ring Road Reconstruction Project, striving for high-precision penetration of the tunnel this year. It was escorted by the survey team led by Li Weichuan of China Railway 14th Bureau.

　　Don’t look at leading the team to get used to it now. When I just graduated, Li Weichuan failed to adapt to the hard work for a while.

　　Despite the difficult conditions, Li Weichuan chose to stick to it when he saw that shield machines were still rare in China at that time and there were very few professionals engaged in shield surveying. He began to constantly learn surveying knowledge from the masters, and rechecked the excavation data and geological conditions over and over again.

　　After many projects, Li Weichuan gradually became the person in charge of surveying. I thought my measurement technology was already very proficient, but in the process of debugging the guiding system of an imported shield machine, Li Weichuan suddenly felt the gap.

　　In order to fight for breath, Li Weichuan made extraordinary efforts. In addition to surveying, he began to actively learn the knowledge of various types of work related to shield machines, and constantly summarized the problems and solutions encountered in practical work. Hard work pays off. In 2014, Li Weichuan successfully obtained the third-level (advanced) certificate of engineering surveyor. In 2021, it also passed the highest professional qualification in the construction industry — — The first-class registered construction engineer examination has completed the transformation from technical personnel to highly skilled personnel.

　　In the past ten years, he has participated in the engineering survey tasks of many important and difficult projects, such as the diversion tunnel of South-to-North Water Transfer Project, the Slender West Lake Tunnel in Yangzhou and the Beijing-Tangshan High-speed Railway.

　　Li Weichuan, Project Survey Director of Beijing Sub-center of China Railway 14th Bureau:Our domestic shield machines are becoming more and more advanced, and now many shield machines have been exported abroad. I think that one day, if their problems can’t be solved, they can consult us in the past. At that time, we will not hide, and we will share some experience and knowledge with them.

Tesla is gradually losing the attention from consumers. From the product point of view, both Model Y, Model 3, Model S and Model X are old products many years ago, and it is difficult to stimulate consumers’ increasingly critical nerves.

Reuters previously said that Tesla had abandoned the production plan of Model 2, a low-priced electric vehicle with a price of 25,000 US dollars. Musk denied this and said that the unmanned taxi Robotaxi will be released on August 8 to fight back.

But in today’s consumption environment, cheap cars are the magic weapon to increase sales, and the significance of Model 2 is obviously greater than that of Robotaxi. Especially for Tesla, which is in the downward trend of sales.

From a macro policy point of view, the situation facing Tesla is even more difficult.In order to protect the interests of traditional car companies, the support for pure electric vehicles in the United States and Europe began to decline, and Europe was also erratic in the transformation of new energy.

In order to slow down the penetration of new energy vehicles in the world and gain more time for the local traditional automobile industry, some policy makers deliberately slowed down the progress of industrial transformation. However, Tesla, the core new energy automobile enterprise in Europe and America, was the most seriously injured.

Musk, who has been involved in the torrent of global economic and industrial games, has begun to face a fierce battle. His embarrassing role also determines that he must point out a new direction for the enterprise-Robotaxi unmanned taxi is the answer he gave.

After all, it can’t be rolled up

Reuters previously reported an exclusive news that Tesla had abandoned the production plan of Model 2, a low-priced electric vehicle with a price of 25,000 US dollars, because the China market was too big, which caused Tesla’s share price to plummet by more than 6%.

Musk, who has always disliked the media, also stood up and responded that "Reuters is lying". However, a few hours later, Musk suddenly announced that Tesla will release the driverless taxi Robotaxi on August 8.

Because Musk didn’t specify which part of Reuters’s content was "lying" and suddenly released Robotaxi unmanned taxi, it shows that Tesla’s cheap car project is very likely to be cut off or postponed.　

Reuters’s news is not groundless. Previously, several people familiar with the matter revealed to the media that Tesla cancelled the development of the entry model Model 2 and turned to the development of driverless taxi business on the car platform.

Providing consumers with affordable electric vehicles has always been the goal pursued by Musk. To this end, in recent years, Tesla took the lead in opening several rounds of price wars.

However, starting from this year, Tesla’s strategy of sinking the market through price reduction has become increasingly difficult to work. Even if Tesla’s $25,000 Model 2 is released, it is already difficult to form enough competitiveness-the price of BYD Qin Plus has dropped to 79,800 yuan this year, which is only $10,000.

The popular dream that Tesla always wanted to do, BYD realized it ahead of schedule. The low-cost model built by China automobile manufacturers through full-stack self-research and mature supplier system can make the product price drop continuously under the blessing of scale effect, so as to truly benefit the people and win the most sinking market.

Of course, the threat of China car companies to Tesla is not limited to low prices, but also poses a threat to Tesla’s Model 3 and Model Y in terms of cost performance.

In recent years, in the press conference of new energy brands in China, the words "the best within N" frequently appear. This clearly reflects a current situation:It’s really difficult to roll the cost performance of products in China, because you will meet more roll kings.. Xiaomi automobile confirms this point. At the beginning of development, SU7 was "sticking to the face" around Tesla Model 3, and the final starting price was 30,000 yuan cheaper than Model 3, which completely forced the palace.

What makes Musk feel uneasy most is probably the unique pricing method of China car companies.

Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, talked about the price of Zhijie S7. He once said that there was a heated debate within the company about the pricing of this model. At present, the prices of the four versions are all at a loss. We just want more consumers to experience Huawei’s products, and hope that the cost can be balanced with the quantity in the future.

I thought everyone came out to make money, but they just wanted to make friends with consumers. Lei Jun once said, "Every time Xiaomi sells a car, it is a loss. The first price of the top version is 350,000, which is also a loss. Finally, it is directly set at 299,900. Anyway, it is vomiting blood."

Of course, car companies are not vomiting blood in vain. Take BYD’s successful experience as an example. In the first three quarters of last year, when the bicycle price dropped by 17,000 yuan, the bicycle cost dropped by 21,000 yuan, the gross profit margin of the automobile business increased to 25.6%, and its earning power even surpassed Tesla.

To put it bluntly, selling cars at a loss is just a means, and its business model is to promote sales through price reduction, and then realize profit through scale effect. Of course, if you really can’t make a profit, it’s also good to "make friends" with consumers, and you can launch new products with lower positioning in the future to achieve profitability.

It’s just that it’s hard for Musk, and China car companies have given up all the roads he wants to take.

Become "Didi"

Musk’s obsession with Robotaxi was reflected long ago. It is mentioned in the Biography of Musk that his grand vision is to build a vehicle that can drive completely automatically without any human intervention.

In this way, Tesla owners can lie at home and let the car work outside to earn money. Users use software to summon Robotaxi like a car, but there will be no driver in the car.

The reason why Musk was able to shout out the release of Robotaxi on August 8 was due to the progress of FSD fully automatic driving.

At the end of March this year, Tesla launched the version of FSD V12.3, and the suffix cancelled Beta. Generally speaking, Beta stands for the Beta version, although Musk has previously explained that the beta suffix of FSD does not mean the beta version in the usual sense, but to reduce the blind trust of car owners. Now removing the FSD after Beta means that Tesla has become more confident in its autonomous driving technology.

FSD V12.3 has made great changes in the algorithm level, completely abandoning the previous methods that relied on manual coding rules and machine learning models, and instead fully adopting the end-to-end neural network AI system.

There are more than 300,000 lines of C++ codes written by engineers in the FSD V11 version control stack, but in the V12.3 version, there are no regular codes, only neural networks. Thanks to FSD’s powerful autonomous learning ability and more than 1 billion kilometers of driving data, FSD’s driving level is rapidly improving.

According to the test of American bloggers, the current version of FSD V12.3 has been able to achieve automatic driving in a variety of complex road conditions, including road conditions without drawing lines, cut-in sidewalks, red-light rails and other scenes.

Moreover, the driving experience of FSD V12.3 is very close to that of an old driver. For example, when passing by a road where there will be an intersection every short distance, FSD V12.3 will not let the vehicle mechanically move closer to the top speed, but choose a human comfortable speed.

This technology is not cheap. The price of FSD in North America is $15,000, and the optional price in China market has to exceed 60,000 yuan. However, Musk has long thought of a solution. According to his vision, the owner who joins the Robotaxi team can make a profit of 30,000 US dollars every year and become a wealth management product to help users repay their car loans. If the vehicle itself can help you make money, it seems that spending more money is nothing.

Despite this, there are still many doubts about whether Robotaxi can save Tesla’s short-term decline.

The vision of making vehicles a financial tool is beautiful. However, even if Tesla can successfully launch Robotaxi on August 8, it will take a certain period of test before it can be widely used.

Especially for driverless taxis, a traffic accident-whether the responsible party is the company’s car or not-will bring great trouble and even a devastating blow to the company in public opinion and law.

Previously, Cruise’s unmanned taxi had a traffic accident in San Francisco. After another car hit a pedestrian, Cruise’s unmanned taxi did not recognize someone under the car in front, and continued to run over people, causing the latter to be seriously injured. With the intervention of California and federal regulators, Cruise announced that all unmanned taxis would be completely shut down for technical safety risk assessment. After that, the Cruise business was shut down, layoffs were substantial, and the valuation was halved.

Tesla’s Robotaxi vision is beautiful enough, but it may also bring unpredictable risks to the enterprise itself.

Stay away from the trend

You know, Model 3 has been on the market for 7 years, and Model Y is already a model four years ago. Today, Tesla is in urgent need of a new explosion. However, the low-priced models can’t compete with China car companies, and the global market price is high and cold, and the prospect of Robotaxi is hard to say clearly. In fact, Tesla’s growth has been hindered.

While Tesla’s sales are stagnant and China’s new energy vehicles are booming, the logic of overseas pure electric vehicle market growth seems to be challenged.

Kang Linsong, Chairman and CEO of Mercedes-Benz Group Co., Ltd., said at the annual general meeting that he would abandon the all-electric vehicle plan. Kang Linsong said that in view of the fact that the popularity of electric vehicles has not reached expectations, Mercedes-Benz will no longer adhere to the original goal of fully turning to electric vehicle sales in major markets before 2030.

GM also made a strong statement that "the company will fully turn to electric vehicles in the future", and it also ended in vain, giving up the goal of producing 100,000 electric vehicles in the second half of 2023 and producing 400,000 trams in the first half of 2024.

According to Edmunds’ insight, in the global market, the average selling price of electric vehicles is $59,400, which is much higher than the $44,800 of traditional fuel vehicles.In today’s global economic slowdown and shrinking demand, it is inevitable that the market space of pure electric vehicles will not be broken if the price is too high.

This is also reflected in Tesla’s sales in the first quarter of this year. The data shows that Tesla delivered a total of 386,810 vehicles, far below the analyst’s previous average expectation of 449,080 vehicles. This is also the first time that Tesla has fallen below the 400,000-vehicle mark since the third quarter of 2022, which is over 8.5% lower than the delivery of 422,875 vehicles in the first quarter of last year.

According to data from Carisyou, a Korean research institute, and the Ministry of Trade of Korea, Tesla sold only one car in the Korean market in January this year in South Korea, the home base of international cheap fuel vehicles.(You are not mistaken).

As a result of various problems, Tesla did not give a clear sales guide in 2024 at the latest financial report meeting, which triggered concerns about Tesla’s sales in the capital market. Tesla’s share price has dropped from the highest point of $299 last year to $172 today, which is not a small drop. It can be seen that investors do not have too many illusions about Tesla’s short-term and medium-term future performance.

Tesla’s share price performance (since listing)

Judging from the changes in the international situation, the situation has not fallen to the side of Musk.

Take the American market for example, in order to protect the interests of traditional automobile manufacturers, they relaxed the emission standards of automobile exhaust, and the support for pure electric vehicles began to decline. In 2032, the proportion of pure electric vehicles in new cars was reduced from 67% to 35%, and it was also stipulated that power batteries must be produced in China, so that consumers could get the government’s price subsidy of $7,500 per vehicle.

A similar situation has occurred in the European market. With the news that European automobile giants have suspended the development of new energy automobile industry or stopped the transformation of new energy in order to maintain their advantages in the field of fuel vehicles, automobile giants have begun to play a game with policies in terms of economic and social effects.

The final result of these games can only make the development trend of European and American automobile industry and new energy vehicles drift away.

Write it at the end

It can be seen that with the rise of new energy automobile enterprises in China, European and American automobile enterprises have suffered a huge impact, and returning to the fuel vehicle market is more like a forced choice than taking the initiative.

Musk himself had a clear judgment on this:

Under the unfavorable situation, the new moat he chose for Tesla is autonomous driving and its derivative Robotaxi market. This basically means giving up the cheap car market, and it is also an attempt to gain more added value.

Whether this direction can bring enough business increment to Tesla, at least at present, is uncertain-especially if the domestic Baidu unmanned taxi has not made enough progress and effect.

For Musk, it is not a comfortable role to be caught in the political and economic games of major countries, but it is also the price of success in that year.

　　"If there is an afterlife, do you want to be a girl or a boy?" When Wang Wenjuan, the head of the UU White Shell Project, raised this question in the public welfare class of a mountain school in Liangshan Yi Autonomous Prefecture, Sichuan Province, few people raised their hands "wanting to be a girl" on the grounds that they felt dirty and troublesome and disliked. "I want to ask this question to understand their gender identity." Wang Wenjuan said.

　　Although this public welfare class of adolescent physiological health knowledge is only for girls, the initial atmosphere is a bit embarrassing. When hearing the words "menstruation", some girls buried their heads in their arms shyly, and some blushed and rubbed their hands. Until they found that the physical and health supplies sent by Wang Wenjuan were exactly what they usually lacked; Many of the physiological coping methods mentioned are not taught by my mother or sister. The confusion about the physiological period in their hearts has been solved little by little. One, two, three … … Girls began to raise their hands to ask questions and interact, and the atmosphere gradually warmed up.

　　When Wang Wenjuan left, everyone blocked this warm-hearted little sister at the door of the classroom and hugged her. A girl insisted on sending her to the school gate and kept saying "Annigu" (Yi meaning: I love you — — Reporter’s note). A girl later wrote to tell her: "The sanitary towel you sent is like a care. I didn’t expect that I could get such meticulous care from others. I know how to protect myself in the future."

　　After entering adolescence, there are always many "question marks" in my heart.

　　During the first physiological period, Xiaofen (a pseudonym), a left-behind girl from a single-parent family in niujie Middle School, Weishan County, Yunnan Province, was not particularly panicked. She remembered what the biology teacher had said and bought sanitary napkins by herself. She didn’t feel well for a few days, but she didn’t tell her grandmother and her father who worked outside the home because she was shy. For the physiological period, she knows nothing about other precautions except that she strictly abides by her classmates’ "Don’t touch cold water and eat popsicles".

　　It was not until the social worker of the "Spring Willow" left-behind girl care project came to the school that Xiaofen participated in the accompanying activities of the "Spring Willow" class and knew how to use sanitary napkins and how to wash underwear during the physiological period.

　　Lu Ying, the director of "Spring Willow" project, and his team visited some mountainous areas in Yunnan and found that "menstrual poverty" is a common phenomenon. Some girls go to the nearest store to buy sanitary napkins, and they have to walk more than ten kilometers, and the types available are very limited; Influenced by their elders, some girls will still use traditional methods, such as toilet paper and menstrual belt, to cope with the physiological period, and social workers will learn to use sanitary napkins after repeated explanations.

　　Like Lu Ying, Ma Yali, project director of Yicang Charity Service Center in Linxia Hui Autonomous Prefecture, Gansu Province, has also discovered the problem of "menstrual poverty" of many girls in rural areas since she participated in charity activities to help poor girls in 2018.

　　When delivering "Xiao Ya Bao" including sanitary products and underwear, Ma Yali talked with local rural girls and learned that they were discovered by their mother only after the second physiological period or even the fourth or fifth time.

　　Ma Yali also learned that many rural girls generally choose "what to buy cheaply" for physical hygiene products, and even some girls don’t change sanitary napkins often during the physiological period in order to save money, and there are also cases of gynecological bacterial infections.

　　"Many girls always have a lot in their hearts after they enter adolescence ‘ Question mark ’ " In the past seven years, in order to help girls in rural areas correctly understand the knowledge of physical health, Ouyang Chenxi, co-founder of Lingmei Public Welfare Organization, has carried out related projects in Sichuan, Zhejiang and other places to help girls aged 11-19 to grow physically and mentally. When she once held an activity in Liangshan Prefecture, she found that some local girls didn’t know why their buttocks were bleeding, why they had a stomachache during their physiological period, and why they couldn’t control their emotions for a few days.

　　"Without sanitary napkins, many rural left-behind girls can’t say it ‘ Pain ’ 。” Wang Wenjuan has been doing public welfare for more than five years, and many remote mountainous areas in Yunnan and Tibet are places that he often goes to. In addition to financial difficulties, she found that local girls still have a strong sense of "menstrual shame". This sense of shame also comes from the outside world.

　　For example, I heard that Wang Wenjuan sent sanitary napkins, and some schools declined to say that "it’s easy to publicize the farewell things, but it’s hard to tell the outside world to send this (sanitary napkin)". Although some schools accept donations, Wang Wenjuan feels that the other side has a subtle attitude of "I wish I could finish donating and leave quickly". Every time this happens, she always "talks about conditions" with the school — — Adhere to the principle of "be sure to give lectures to children" and ensure that every girl who receives hygiene products can hear physiology classes and psychological counseling classes. "I want to bring love to the children by giving away hygiene products." Wang Wenjuan said.

　　Giving away physical hygiene products is like "far from hydrolysis, near thirst"

　　In Ouyang Chenxi’s view, the "menstrual poverty" of many rural girls is closely related to family economic conditions, family members and the degree of care from the outside world. No one tells them how to deal with such a private matter as the physiological period, and they don’t have much money to buy sanitary products themselves. Some left-behind girls’ daily pocket money is only more than 10 yuan. When it comes to "unlucky days", they always blush and ask their grandparents for money to "buy that".

　　"Giving physical hygiene products to girls in remote mountainous areas is like ‘ Far hydrolysis cannot quench thirst ’ 。” Wang Wenjuan knew that "menstrual poverty" could easily lead to gynecological diseases and psychological problems of adolescent girls.

　　When she was volunteering, Wang Wenjuan learned that a girl had severe dysmenorrhea, local itching and other symptoms, but there was no one at home to accompany her to see a doctor. She tried to take the half-assed girl to the local hospital, but when she heard "going to gynecology" at the door of the hospital, the girl turned her head and ran away. Wang Wenjuan later learned that this girl was very resistant to the word "gynecology" and would rather not see a doctor than go to "that place".

　　However, Wang Wenjuan has also found some positive changes in the past two years. On one occasion, she went to three township schools in Shangrao, Jiangxi Province to give away sanitary products and give public lectures. Teachers from the county school also came to attend the lecture. After class, they also invited Wang Wenjuan to give a lecture in the county, and said, "Children in the county may not need donated sanitary products, but they need such physical hygiene classes." This recognition made Wang Wenjuan feel that the effort was worthwhile.

　　“‘ Menstrual poverty ’ It is likely to affect girls’ physical and mental health development, including schoolwork. " According to Dr. Long Di, a professor at the Institute of Psychology of the Chinese Academy of Sciences and director of the Center for the Protection of Children and Families, some girls lack physical hygiene products and the intimate care of adults around them. Coupled with the mentality of menstrual shame shaped by social culture, they will have negative emotions such as tension, anxiety and fear, and even dysmenorrhea. "It is necessary to strengthen education and support for girls’ physiological period and mental health."

　　How to strengthen the physical and mental health education and support for underage girls

　　"In addition to giving rural girls more volunteer services in terms of physical health knowledge, they must be made to identify with and love women’s identity." Ouyang Chenxi has been thinking about how to add more experiential volunteer service activities to the public welfare science popularization activities of physical health knowledge in the future, so as to better perceive girls’ emotions and stimulate their self-identity and positive growth from the inside out.

　　According to Long Di, according to the UN Convention on the Rights of the Child, to realize the best interests of children should ensure the two major needs of children’s safety and development. For the healthy growth of underage girls, she believes that parents, teachers and education departments are duty-bound, especially the education department should work with relevant experts and parents to formulate effective measures to effectively protect and care for the healthy development of underage girls’ physical health.

　　In addition, Long Di mentioned that the physical and mental health education services conducted by non-governmental public welfare organizations have been formed in recent years, and some ways have been explored. It is suggested that volunteers of public welfare activities pay special attention to respecting the living customs in underdeveloped areas, and do not have the attitude of "I am right, you are backward" and "I want to change you", but should explore with the recipients how to change the customs harmful to women’s physical and mental health, so that girls in poor areas have the opportunity to create a happy life.

　　"There are too many girls who need sanitary napkins, and there are too many lists received, which are all backlogged, but the fundraising can’t keep up." At present, Wang Wenjuan is facing a lot of pressure to raise funds. She said: "Donating physical hygiene products is just a way. Wherever you donate, you should talk about the course. I hope that the needs and difficulties of poor girls can be well-intentioned and gently protected, and don’t let ‘ Menstrual poverty ’ Happened to children. " (Reporter Jiao Minlong)

"I am an engineer myself. I have done both hardware and software. Therefore, our zero run will definitely have the culture of engineers. " The founder of Zero Run once said this.

The Science and Technology Man Created by The Big Bang Theory

Zhu Jiangming and his zero-run car really have a "science and technology man" temperament. Everything is "technology is king" and independent research and development are highly respected. Judging from the S01, the first mass production car with zero running, all the core components should be self-researched, and there is already the strength of "no madness and no survival".

The industry is not the first to build such a "science man". Nowadays, the zero-running car is very much like the first electric car enterprise in China. Zhu Jiangming’s engineer temperament is also reminiscent (known as "the boatman").

BYD started its electric layout at the end of its own brand, and it caught up with the best time of electric car in China. Soon after the zero-run car started, can the running method of "self-research"+"self-construction" still win?

The tactics of technical men: super learning ability

Zhu Jiangming, founder of Zero Run Car, and Wang Chuanfu, president of BYD Co., Ltd.

"We started with the enterprise dispatching machine in 1993 and transformed the security equipment in 2001. We have experienced two successful entrepreneurial processes from 0 to 1." Zhu Jiangming recalled and said.

In 1993, 26-year-old Zhu Jiangming and Fu Liquan, the current chairman of Dahua Co., Ltd., pooled 5,000 yuan to set up Dahua in a primary school in Hangzhou and started their business. Zhu Jiangming, who graduated from Zhejiang University majoring in telecommunications, is good at embedded algorithm and chip-level combination of software and hardware at the bottom of the computer, and Dahua originally used this embedded technology for enterprise dispatching machines.

In 2001, Dahua’s main business turned to security, which made Zhu Jiangming completely a layman. By studying and studying, Zhu Jiangming led the team to develop 8-channel embedded DVR in 2002. This technical breakthrough in the security industry has enabled Dahua to enter a period of rapid development, laying a foundation for the future development of Dahua.

Zhu Jiangming, who once couldn’t tell all the camera parameters, became an expert in video security technology. HDCVI (high definition composite video interface) video transmission technology invented by Zhu Jiangming was officially released by Dahua in 2012, which triggered a technical earthquake in the field of video transmission.

As a coaxial high-definition transmission technology, HDCVI can realize the transmission of megapixel video over 500 meters, breaking through the bottleneck of resolution of traditional analog technology. In 2013, the international HDcctv Alliance announced the acceptance of HDCVI as an international standard, and HDCVI technology became the first technical specification in China security industry to be included in the international standard. In December 2014, HDCVI technology and standards were included in GA/T1211-2014 "Technical Requirements for Security and Prevention of HD Video Surveillance System".

With the invention of HDCVI alone, Zhu Jiangming opened the door to wealth and freedom. "Every year, relying on HDCVI, Zhu Jiangming can receive a lot of patent fees from all over the world." Insiders said. However, Zhu Jiangming is still not satisfied. In 2015, he decided to create a zero-running car and wanted to realize the third "0 to 1" change in his life.

Boatman: You can make everything yourself.

Wang Chuanfu, a fellow science and engineering man, is one year older than Zhu Jiangming. The advanced story of "Brother Boatman" has long been a household name in China. Comparing the two, "science and engineering men" seem to like to do the challenge of "nothing can be done".

Wang Chuanfu likes to manage enterprises by means of management technology. "Technology is king and innovation is the foundation" is the fundamental development concept of BYD put forward by Wang Chuanfu. Wang Chuanfu does not impose restrictions on BYD. He thinks that everything can be made by himself, and what is made is more useful than what is bought at a high price. He thinks that technology patents are all’ paper tigers’. The remarks that "20 engineers support a mechanical arm" and "cars are just a pile of steel" make "science man" Wang Chuanfu look simple, arbitrary and conceited. He enthusiastically pursues technological innovation. He uses strong creativity and indigenous methods to break the technical blockade. He despises unreasonable business order and game rules. His growth mode is simple and direct: if you don’t help me, I will do it myself.

In 2003, BYD produced more lithium batteries than Sanyo, Sony and Panasonic, accounting for 60% of the global market. At that time, Japanese companies had established a highly automated battery production line, and the mechanical arm could replace a lot of labor. When representatives of Japanese enterprises visited BYD, they were amazed at the production efficiency of BYD’s semi-automatic+manual "human sea tactics". In that crazy era, Wang Chuanfu made full use of domestic low-cost human resources to subvert the monopoly position of Japanese battery industry at that time.

In 2003, BYD began to transform into the automobile industry. Wang Chuanfu’s decision inevitably met with some opposition. Wang Chuanfu said confidently, "I am determined to do it, and I believe it can be done. Judging from the road BYD has traveled, more than 98% of my decisions are correct! " "I will work as a car for the rest of my life!"

Shortly after purchasing Qinchuan Automobile, Wang Chuanfu asked his men to collect several boxes of books on automobile technology for him in bookstores in Xi ‘an and Beijing. When Wang Chuanfu invited car design expert Lian Yubo to join BYD, Lian Yubo asked, "Do you know anything about cars?"

Wang Chuanfu honestly replied, "I like cars. I have read hundreds of books."

At the beginning of BYD’s transformation, it was sung down by the capital market and its stock was badly sold. Wang Chuanfu once promised fund managers that entering the car "will bring the company 30 million profits and the production and sales of 30,000 cars one year later". As a matter of fact, in the first two years of BYD Auto, it only spent a lot of money to build a "Fleur" model.

BYD’s First Model-"Fowler"

"Fowler" is basically BYD’s "behind closed doors" product, and the dealers can’t laugh and cry when they look at the "four unlike" in front of them, so the sales volume will naturally not be ideal. In 2005, BYD’s annual report showed that BYD sold only 15,993 cars, with a loss of 91.3 million RMB.

How to build a good car in a short time? BYD adopts reverse research and development. The so-called reverse research and development is to disassemble mature cars, learn from the advantages of other people’s products and develop their own products in reverse. This is more time-saving than saving R&D funds from 0 R&D..

In 2005, BYD launched the first car that really opened the market for BYD-"F3". Even Wang Chuanfu was surprised. In 2006, Wang Chuanfu said, "The current hot sale is completely unexpected. At first, I thought it would be more satisfactory to sell 2,000 units a month. However, according to the current sales capacity, we can walk 10,000 units a month. " Why can "F3" succeed? Because F3 was almost a replica of the best-selling car Toyota Corolla at that time, and the price of F3 was only half of the former.

BYD F3, a replica of Toyota Corolla

Like making batteries, BYD has almost completely produced its own products from production line to automobile parts assembly. At that time, BYD workers said that except for glass and tires, everything on the car was made by BYD itself; It seems that BYD, who has only been in the business for two years, has accomplished an impossible task, which has greatly saved the manufacturing cost and formed a market advantage.

In 2006, BYD quickly launched F3e, an iron-lithium electric vehicle, based on F3 platform. The motor, reducer, battery components and control system of F3e are all developed and produced by BYD. Although the F3e electric vehicle was not successful at that time, it still showed Wang Chuanfu the advantages of electrification. BYD concentrated its R&D efforts on the research and development of its first-generation hybrid technology DM module. At this point, Wang Chuanfu began an all-round attack on fuel vehicles, electric vehicles and automobiles.

Today, BYD has almost become an all-round player. We can produce 2.0T in-cylinder direct injection, dual-clutch DM plug-in module that can be compared with Toyota Prius, and a three-electric technology platform including battery manufacturing, etc. In the "China Automobile Technology Development Report" released in December 2017, BYD’s patent technology is ranked first among mainland automobile enterprises.

Zero Run: Self-research+Self-creation

Can BYD’s "all self-produced" model still work today?

Lingpao Jinhua base welding workshop

"All car companies with a long history will eventually go to the road of" self-research "and" self-made ",and zero running is only the first to make the right choice." Zhu Jiangming said. Unlike the internet, zero running is low-key and crazy. In the 40 months since the establishment of Zero Run Automobile, we have carried out the values of "technology is king" of science and engineering men, and "the foundation for IT people to build cars-insisting on independent research and development of core technologies", which makes us seem to see the shadow of BYD in that year.

Independent research and development of automatic driving system

Different from BYD’s generation of car-making forces more than a decade ago, the focus of automobile development is on automobile mechanical technology. Vehicle design; Nowadays, the new trend of automobile electrification and intelligence has put forward new topics for the new generation of car makers.

"50%-60% of electric vehicles are actually related to electricity, and the composition of electricity is not necessarily less than that of machinery. The underlying technology will have a large number of electrical components to cooperate and interact. For the next generation of automotive hardware, especially the underlying electronic and electrical architecture technology, zero running based on Dahua technology background is completely advantageous. " Zhu Jiangming explained.

"Zero Run is the second vehicle manufacturer in the world with complete independent research and development capabilities for smart electric vehicles." Zhu Jiangming said confidently.

Different from the situation that other manufacturers rely on, Zero Run benefits from the technical advantages of Dahua Co., Ltd., and the cameras, sensors, AI autopilot chips, core software and algorithms involved in technology have been independently developed. At present, the zero-run car has achieved L2.5-level automatic driving, which can support L3-level remote upgrade. In 2020, it is planned that all models of zero-run cars will achieve L3 level through software upgrade, and in 2021, L4/L5 automatic driving test will be carried out in a small scale. After 2025, it will reach the L4/L5 level of mass production.

Comparison Table of Intelligent Driving Assist Function between Zero Run S01 and Competing Vehicles

What is the relationship between the chips in the lowest layer of intelligent vehicles? What is the embedded algorithm? Zhu Jiangming and Dahua, who have been dealing with electrical architecture technology for 20 years, have taken a fancy to the development opportunities of automobile intelligence and electrification, which is also the advantage of zero-running into the electric vehicle market. In addition, more importantly, the core technology of domestic intelligent networked automotive technology is missing, and Zero Run wants to fill the gap in automotive smart chips and intelligent algorithms. Zero-run car is jointly developing AI autopilot chip-Lingxin 01 with Dahua Co., Ltd. According to the relevant personnel of Zero Run, Lingxin 01 will have the ability of deep autonomous learning, and its computing power will reach the mainstream level in the industry, while supporting multi-chip flexible combination. At present, Lingxin 01 has entered the stage of integration verification, and it is expected to carry out real vehicle testing in the second quarter of next year.

Self-developed body platform

Different from BYD’s reverse research and development, Zero Run claimed that it had developed three body platforms-T-Platform, S-Platform and C-Platform from the beginning. The Zero Run S01 is the first mass production model based on S-Platform.

S01 is based on the design of electric vehicle platform, and the components of the whole vehicle, such as body, chassis, powertrain and battery pack, are all designed independently by zero-run. S01 curb weight is only 1240 kg, and the battery module accounts for 80% of the vehicle width. In this numerical performance, Tesla is 78%, while the average value of the electric vehicle industry is 60%. Its body-in-white weighs only 215 kg, accounting for 17% of the curb weight, while the average value of the body-in-white of electric vehicles is 20~25%.

Zero Run S01 Body-in-White

Platform S is designed with a toughened cage structure around the protection of the passenger compartment to ensure that the passenger compartment has sufficient rigidity and strength. The platform expansibility was also considered in the early stage of research and development, and the architecture can be extended from the current S01 two-door four-seat to five-door cars and models. S01 body-in-white roof adopts embracing laser welding technology to optimize the solder joints; The car body adopts a large number of processes such as thermoforming and rolling, and the proportion of thermoforming and high-strength steel is over 70%. Important anti-collision paths such as A-pillar /B-pillar/door anti-collision beam and front cabin are thermoformed, and the tensile strength reaches 1300Mpa；. The inner and outer doorsills are rolled, and the tensile strength reaches 1180Mpa.

Self-developed "Three Electricity" System

"Hercules" electric drive assembly

As the core three-electricity technology of electric vehicles, zero-running is all independently developed except batteries. Zero-run S01 electric drive is code-named "Hercules". Zero-run is fully developed forward, and the lightweight design scheme of "three in one" of motor, controller and reducer and "five in one" of motor controller is adopted.

Hercules is divided into an upper part and a lower part. The upper part is a "five-in-one" motor controller, which is divided into an upper case and a lower case.
Case) section. The upper box part is DCDC (vehicle power supply), MCU (motor controller) and PDU (high voltage distribution module), and the lower box part is VCU (vehicle controller) and OBC (on-board charger). The lower part is the driving motor and reducer. The upper part and the lower part are connected by a flexible fixed damping mechanism to form a "three-in-one" system.

This set of electric drive assembly has completed the accelerated life test of 500,000 kilometers, and it is also the first one in China to complete 120,000 continuous peak power start and peak power energy recovery braking cycle life tests. At present, it has mass production capacity. Compared with the traditional design with the same performance, "Hercules" reduces the weight by 30% and the volume by 40%, and the overall mass is only 91kg, but it still achieves the maximum power of 125kw and the peak torque of 250Nm； as the electric drive assembly. The highest efficiency of the system reaches 93.6%, and the high efficiency ratio exceeds BMW i3 by 94.49%.

Comparison Table of Motor Efficiency and Electric Control Parameters between Zero Run S01 and Competing Vehicles

After the electric drive assembly, we are looking at the battery pack of S01. The power battery PACK of a zero-run car is all independently developed except the battery cells, which is "the highest degree of independent research and development of battery packs in domestic automakers except BYD, including modules, PACK, BMS hardware and software". Due to the integrated thermal management scheme of cold and heat, the charging and discharging efficiency of the system reaches 97.7%, and the discharging efficiency can still reach 92.5% in the area of -15 degrees. The four-in-one shunt is used for current detection, which makes the SOC accuracy reach 3%; Adopt single cell bipolar double insurance to reduce the risk of thermal runaway diffusion; The battery box shell adopts integrated aluminum casting process, which reduces the total weight of the box by 40%.

Comparison Table of Battery Pack Parameters between Zero Run S01 and Competing Vehicles

Although Zhu Jiangming thinks that Zero Run wants to be Huawei in the automobile industry, as far as the current measures of Zero Run are concerned, they are more like taking the old road of BYD. Zhu Jiangming may not be as fanatical as Wang Chuanfu, but the values of "science man" and "technology is king" will make them reach the same goal by different routes.

S01, the first production car with zero running.

Is it reliable for "science man" to build a car? Judging from the successful example of BYD, the hard-core ones are very reliable. However, it is not enough to drill only in technology. It is indispensable to do a good job in "humanity" and "feelings" of automobiles, and "science and technology men" also need to open their arms and embrace the world.

BYD’s success is not only due to its tireless innovation, cost reduction, hard battle, "reverse development", its ability to appeal to consumers, but also its necessity to open the market. In the past year or two, BYD’s "Dynasty Series" has sold well, not only because of the three-electric technology, 2.0T engine, dual-clutch gearbox and DM hybrid, but also because of Wolfgang’s dragon face. BYD has gone a long way from a technical expert to a product expert, and it is still on the road.

Nowadays, in terms of intelligence and electrification, traditional car companies at home and abroad have begun to display their technical reserves and launch wonderful products. It’s a long way to go to the technical master. Let’s see if he can beat his opponent. (End)
