Look with your heart and talk seriously-

On December 28th, Xiaomi Automobile Technology Conference was held in the National Convention Center, which officially revealed the progress and breakthrough of five core technologies of Xiaomi Automobile, and ushered in the first appearance of Xiaomi SU7, the first product of the platform. The design, performance, battery life, safety and other details of SU7 were made public for the first time. Next, let’s briefly understand the core technology of the big show at the meeting and the details of Xiaomi SU7, and finally we will analyze and summarize it.

Release of five core technologies

At this conference, Lei Jun mainly introduced the five core technologies of Xiaomi Automobile: electric drive, battery, large die casting, intelligent cockpit and intelligent driving.

Xiaomi "super motor"

The speed of V6 and V6s which have been mass-produced is 21,000 rpm. Among them, the V6 super motor has a maximum power of 220kW and a peak torque of 400N·m, and is built with a 400V architecture. The V6s super motor has a maximum power of 275kW and a peak torque of 500N·m, and is built with 800V architecture. As for the V8s, which has not been mass-produced, the speed is as high as 27,200 rpm, which is the first in the industry from the data point of view, but it will not be available until 2025.

CTB integrated battery technology

The integrated efficiency of CTB integrated battery of Xiaomi Automobile reached 77.8%, which increased by 24.4% and released the height of 17 mm.. At the same time, the full-stack self-developed battery management system equipped with ASIL-D’s highest functional safety level can collect data in real time, encrypt the cloud through the private network for analysis and early warning, and realize active power failure within 4ms when necessary.

9100t Super Die Casting

The mold force reaches 9100t, and Xiaomi’s self-developed visual large model quality judgment system can complete the inspection within 2 seconds, with 10 times higher efficiency than manual work and 5 times higher precision than elite. With the application of this technology, 72 parts of the back floor of Xiaomi automobile are integrated, 840 solder joints are reduced, the overall weight is reduced by 17%, and the production hours are greatly reduced by 45%. In terms of material research and development, Xiaomi has developed a high strength, high toughness and heat-free environmental protection die-casting material "Titan alloy".

Full-stack self-developed intelligent driving technology

The industry’s first three key technologies, namely, adaptive zoom BEV technology, large road model and super-resolution occupation network technology, can be combined with the large air-to-end perception decision model, and can accurately park in the 0.05m mechanical garage. Lei Jun said that it is estimated that more than 100 cities can start urban assisted driving by the end of 2024.

"People-centered" Intelligent Cockpit

1.49S starts at top speed, the cockpit system is upgraded for 3 minutes, and the whole vehicle is upgraded for 30 minutes. It has a strong ecology, deeply adapts to mainstream applications, and more than 5,000 applications get on the bus. Moreover, the mobile phone X car is interconnected and connected across terminals, and the mobile phone application PIN is put on the car anytime and anywhere, and the car machine is native in seconds. In addition, the huge hardware ecology, the mijia equipment, and no feeling of getting on the bus. Car IOT hardware ecology is fully open to the public and freely develops various applications.

Xiaomi SU7 has bright parameters.

With the blessing of five core technologies, the core competitiveness of SU7 has the following points:

The maximum power is 495kW, the acceleration time is 2.78 seconds per 100 km, the braking distance is 33.3m per 100 km, and the maximum speed can reach 265 km/h, which exceeds Taycan Turbo and Model S.

CLTC has a mileage of 800 kilometers, and supports 800V super fast charging, supporting 200 kilometers battery life in 5 minutes and 510 kilometers battery life in 15 minutes.

The car is equipped with five screens, including a 16.1-inch central control screen, a 56-inch HUD, a 7.1-inch instrument panel and two millet tablets in the rear seat. The car machine uses the latest 8295 car and chips and the 澎湃 OS interactive system, which can make the car machine of Xiaomi SU7 highly integrated with Xiaomi mobile devices and even intelligent furniture, and the accounts can be interoperable, so applications can be directly used on the car.

Full-stack self-developed intelligent technology and self-developed sensing technology, self-developed adaptive zoom BEV technology, large road model and super-resolution network technology are adopted to achieve a comprehensive leap in visibility accuracy, sensing accuracy and control accuracy.

The length, width and height of Xiaomi SU7 are 4997/1963/1440mm and the wheelbase is 3000mm. The drag coefficient of Xiaomi SU7 is only 0.195Cd, which is the lowest in the world.

The super-large die casting technology adopted has 90.1% high-strength steel and aluminum alloy, the highest strength of 2000MPa and the torsional stiffness of 51000 N m/deg.

Can we achieve "leapfrogging"?

At the meeting, Lei Jun said that he put high demands on the R&D team, and the design goal was to start from 100 "first, only and most", with the goal of building dream cars in a new era of automobile industry, becoming the top five automobile manufacturers in the world in the next 15 to 20 years, and working hard for the overall rise of China automobile industry.

First of all, we can be sure that the technologies released at the Xiaomi conference are not bad, and the Xiaomi SU7 has no obvious shortcomings at present. The explosion potential in terms of flow, product strength and design has been demonstrated, but after careful study, Xiaomi Automobile has no more prominent highlights. Some of the technologies it shows are "far ahead" or "pioneering". In fact, some friends have mass-produced them to real cars and launched them on the market.

For example, Xiaomi Automobile will adopt CTB technology in its battery system. As early as last June, BYD took the lead in releasing CTB technology in the industry and installed it on its BYD Seal model. Although the volume utilization rate of CTB battery released by Xiaomi is higher than that of BYD, the volume utilization rate of 77.8% is not the highest. Previously, the volume utilization rate of the "BRIC battery" released by Extreme Krypton Automobile has reached 83.7%.

Another example is Xiaomi’s 9100t super-large die-casting, with a press of 9100t, but Tucki has already used a press of 12000t, and the largest die-casting machine equipment factory in China is developing a press of 20000t. Therefore, 9100 tons is not leading, only the mainstream.

At the same time, at present, the main product details of Xiaomi SU7 are almost fully disclosed, leaving only the last "card"-price, which is also the most controversial place. At the meeting, after comparing various models, Lei Jun said: "Let’s stop calling 99,000 and 149,000. This is impossible, but we should respect technology." In other words, Xiaomi SU7 is likely to fall in the price range of 200,000-300,000.

But can the price range of 200,000-300,000 coincide with Xiaomi’s existing user base? You know, at the beginning of Xiaomi’s announcement to build a car, most of the voices on the Internet hoped that Xiaomi would knock down the price of the car. This time, the pricing may exceed the budget of most people. More importantly, the price range of 200,000-300,000 is actually the most competitive range of new energy vehicles in China. For consumers who can accept this price range, it is still unknown whether SU7 can meet their demand points, and Xiaomi Automobile currently lacks brand recognition and trust, which can actually give consumers little confidence.

For a long time, Xiaomi has given people the impression that it has amazing hard power and amazing cost performance. But this time, Xiaomi obviously didn’t want to continue to take the civilian route, and changed to a mid-to high-end route. The price exceeded expectations, and the road would naturally be more difficult. In addition to the price, the Xiaomi car that everyone expects unanimously is a model that can come up with some subversive new technologies. However, the actual situation of Xiaomi SU7 seems to be almost interesting, and it seems that people have not been able to see the unique side of Xiaomi.

However, in any case, it is worthy of tribute that Xiaomi Automobile has taken a brave first step seriously. Xiaomi, who has crossed the border to the automobile field, has a lot of core technologies. Starting from the lowest technology, it has spent ten times to build a good car. At the same time, Xiaomi Automobile has natural traffic and user attention, which not only helps to promote healthy competition in the industry, but also is likely to become a key role in leading the next development trend. Finally, let’s look forward to next year, and Xiaomi Auto will bring us more surprises!

[Common War Epidemic] The implementation of China’s car ownership will be postponed at the end of the year or in areas beyond the United States where the National Six Standards have not been implement

　　Cctv news(Reporter Wang Jiazhu) The joint prevention and control mechanism of the State Council held a press conference at 15: 00 on April 9. Cai Ronghua, deputy director of the Industrial Development Department of the National Development and Reform Commission, Sun Guangqi, director of the Economic Construction Department of the Ministry of Finance, Wu Xianfeng, deputy director of the Atmospheric Department of the Ministry of Ecology and Environment, and Wang Bin, head of the Consumption Promotion Department of the Ministry of Commerce, introduced the situation and answered questions from the media.

　　The epidemic situation will not affect the long-term positive trend of China’s automobile industry

　　Cai Ronghua, deputy director of the Industrial Development Department of the National Development and Reform Commission, said that although the COVID-19 epidemic did bring great impact and downward pressure to the automobile industry in a short time, it was temporary.

　　"According to the statistics of industry associations, 1— In February, automobile production and sales decreased by 40% year-on-year, of which February alone decreased by 80% year-on-year. " Cai Ronghua said that as the national epidemic prevention and control situation continues to improve, automobile production and sales are gradually picking up. At present, the daily output has gradually recovered to more than 75% of the same period last year, and the dealer’s orders have returned to more than 65% of the normal level. The resumption of automobile production has been fully launched and the market sales are also recovering. At the same time, the inventory of imported parts of domestic enterprises is relatively abundant, and some increased orders are also in transit, so the production of vehicle enterprises has not been affected by imported parts.

　　Wang Bin, head of the Consumption Promotion Department of the Ministry of Commerce, also said that China’s automobile production and sales have been declining for two consecutive years, indicating that after years of rapid growth, the whole industry has gradually entered a stage adjustment platform, but this does not mean that automobile sales will continue to decline, and China’s automobile consumption has not yet reached the "ceiling" of development. He said that in the next decade, China’s automobile consumption still has a very large room for development.

　　The implementation of the national six emission standards has not yet been implemented.

　　Wu Xianfeng, deputy director of the Atmospheric Department of the Ministry of Ecology and Environment, said that the COVID-19 epidemic did have a great impact on the automobile industry. In terms of the implementation of emission standards, it mainly affected the supply of new car parts, the certification of new car products and the sales of stock cars, and the most important impact on the national six was the control of particulate matter emission. Hubei Province and Wuhan City, which are most affected by the epidemic, are the main areas of automobile production in China, and the impact is nationwide. In addition, the recent spread of overseas epidemic has also affected the global automobile supply chain in China.

　　Wu Xianfeng revealed that the Ministry of Ecology and Environment is considering appropriately delaying the implementation in areas where the national six emission standards have not been implemented, that is, appropriately extending the production transition period of automobile production enterprises and appropriately extending the sales period of the national five inventory vehicles. "Once this policy is introduced, it will be announced to the public as soon as possible."

　　At the end of this year, China’s car ownership will surpass that of the United States.

　　Wang Bin introduced that at present, with the continuous improvement of domestic epidemic prevention and control situation, automobile enterprises have fully resumed work and production, and the market demand has steadily picked up. In late March, the automobile sales of retail enterprises monitored by the Ministry of Commerce increased by 8.9% compared with that in late February. According to statistics from china automobile dealers association, 1.04 million passenger cars were sold in March, which was 37.5 percentage points higher than that in February.

　　In recent years, China’s automobile consumption has mainly shown four characteristics: the scale has been growing, automobile production and sales have been ranked first in the world for 11 consecutive years, and China’s automobile ownership is expected to surpass that of the United States by the end of 2020. The structural adjustment has been accelerated, and the number of family cars owned by rural residents has increased by 15.5%, which has been significantly higher than the growth level of cities and towns for five consecutive years. The level has been gradually upgraded, and the market share of mid-to high-end passenger cars has been expanding. SUV sales accounted for 43.7%, 1.5 percentage points higher than the previous year. Green development is prominent, and the sales volume of new energy vehicles exceeds 1.2 million, accounting for more than 50% of global sales.

　　The extension of preferential policies for purchasing new energy vehicles for two years mainly considers these three points.

　　According to the decision of the CPC Central Committee and the State Council, the central government subsidized the purchase of new energy vehicles from 2009, and exempted the vehicle purchase tax of new energy vehicles from September 1, 2014. On March 31st this year, the executive meeting of the State Council decided to extend the two preferential policies of new energy vehicle purchase subsidy and vehicle purchase tax exemption due at the end of this year for two years.

　　Sun Guangqi, director of the Economic Construction Department of the Ministry of Finance, said that the introduction of this policy is to help solve problems and promote high-quality industrial development. China’s new energy industry started early, started well and developed rapidly, but there are some practical difficulties at present, mainly because the manufacturing cost of new energy vehicles is still relatively high, which makes it difficult to compete with traditional fuel vehicles and needs continued support. The second is to conform to the development trend and improve the comprehensive competitiveness. The third is to hedge the impact of the epidemic and promote automobile consumption. In January and February, the production and sales of new energy vehicles decreased by 63.8% and 59.5% respectively compared with the same period of last year. Extending preferential support policies will help stimulate the consumption of the automobile market, hedge the impact of the epidemic, and also help support related industries and enterprises to speed up the resumption of production.

　　25 provinces and cities have cancelled the restrictions on the removal of used cars.

　　The data shows that in 2019, the number of used cars in China was 14.923 million, an increase of 8% year-on-year, and the transaction volume was nearly one trillion yuan. However, the proportion of second-hand car transactions in new car sales is only about 1/3 of that in developed countries. According to this calculation, the transaction volume of used cars in China should be close to 40 million in theory, and there is huge room for development. Since 2016, China has deployed and cancelled the policy of restricting the movement of used cars, requiring that all regions should allow qualified used cars to move in except Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other key areas for air pollution prevention and control, and allow qualified used cars to trade and circulate in this province and city.

　　Wang Bin introduced that so far, 25 provinces and cities outside the key areas of air pollution prevention and control have explicitly cancelled the restrictions on relocation, and the relevant areas have also cancelled the restrictions on relocation within the province. Benefiting from this, in 2019, the proportion of cross-regional transfer of used cars increased by 8.7 percentage points compared with 2015.

　　"The introduction of the policy of reducing the value-added tax of used car distribution enterprises by 0.5% of sales in the State Council is a milestone for the development of used car industry, which will help promote the scale, specialization and brand development of used car enterprises, help accelerate the release of used car consumption potential in the market, and create greater market space for new car consumption." Wang Bin said that the next step will be to speed up the revision of the Measures for the Administration of Second-hand Car Circulation, further promote the implementation of the policy of removing the restrictions on the movement of second-hand cars, and promote the free circulation of second-hand cars.

　　One million diesel trucks will be eliminated in these two areas this year.

　　Wu Xianfeng, deputy director of the Atmospheric Department of the Ministry of Ecology and Environment, said that in the first half of February this year, due to the double influence of the Spring Festival holiday and the epidemic situation, the national traffic flow dropped significantly. In Beijing, Tianjin and Hebei and surrounding areas, road freight dropped by 77% and passenger traffic dropped by 39%, which directly brought about a reduction of vehicle pollutant emissions by about 50% and a reduction of nitrogen dioxide concentration in the air by about 30%.

　　Wu Xianfeng said that so far, China’s traffic flow has basically returned to the normal level, and pollutant emissions have also returned to the normal level. "In order to further control motor vehicle pollution and reduce vehicle emissions, we have guided more road transportation to railway transportation. At the same time, strengthen supervision and continuously improve the quality of vehicle oil. The other is to steadily promote the implementation of new vehicle emission standards and further eliminate high-emission old vehicles. "

　　According to reports, since 2013, China has eliminated more than 27 million yellow-label vehicles and old high-emission vehicles. This year, it will promote the elimination of 1 million diesel trucks in Beijing, Tianjin and Hebei and surrounding areas and Fenwei Plain, which can reduce the emission of motor vehicles by more than 30% and particulate matter by more than 50%, and other parts of the country will continue to advance.

　　This year, more than 600,000 charging piles will be added to support more vehicles in residential areas.

　　By the end of last year, the total number of charging piles in China had reached 1.22 million, including 520,000 public piles and 700,000 private piles. The charging facilities have covered 404 cities across the country.

　　Cai Ronghua introduced that in the next step, the country will continue to increase the construction of charging infrastructure. First, combined with the renovation of old residential areas, it will guide relevant parties to jointly carry out the construction and operation of charging infrastructure, and support multiple vehicles in residential areas, that is, several vehicles share one pile and share parking spaces nearby, so as to solve the problem of building piles in residential areas. The second is to speed up the formation of a public charging network with moderate advance, fast charging and slow charging supplemented in highways, cities and villages, and encourage the demonstration of the use of power exchange mode. The third is to strengthen the research and development of new charging technologies and improve the digitalization and intelligence level of charging services.

　　According to the survey of trade associations, it is estimated that the investment will be about 10 billion yuan this year, with about 200,000 new public piles, more than 400,000 new private piles and 48,000 public charging stations.
