Huawei is strong and empowered, and the new M7 in the world will definitely exceed 120,000.

In this era, the new energy automobile industry is facing a great change in intelligence, and in this change, the new M7 is undoubtedly a bright star to lead the trend. With the rapid development of science and technology, intelligence is not only a trend, but also an inevitable choice for travel in the new era. With its unique "three-intelligence ceiling" hard-core technical strength, the new M7 has successfully raised the benchmark of intelligent travel to a new height. From intelligent driving to intelligent cockpit to intelligent safety, it has successfully attracted everyone’s attention. On December 26th, it was mentioned in the press conference on the whole scene of the M9 and Huawei that the cumulative number of new M7 in the world has exceeded 120,000, among which more than 60% of users choose the smart driving version, and the monthly delivery capacity will reach 30,000 from January next year.

The top choice in the field of intelligent driving, Huawei ADS 2.0 breaks the imagination of intelligent driving.

For the current users, intelligence is a crucial factor when choosing a car, and the new M7 in Wenjie is equipped with HUAWEI ADS 2.0 advanced intelligent driving system, which not only subverts the traditional concept of intelligent driving, but also brings excellent driving pleasure and travel convenience to users.

When the vehicle is running, HUAWEI ADS 2.0 enables M7 to perceive the surrounding environment in real time through the precise integration of 27 sensing hardware, and realize the accurate perception and recognition of the whole scene and all weather. This not only improves the safety of driving, but also makes users feel a more intimate connection with the vehicle.

The power of intelligence is not only manifested in the driving process, but also throughout the entire travel experience. The NCA intelligent driving system of the new M7 can identify all kinds of situations around the vehicle more accurately through various sensors such as laser radar, making travel safer and easier. In addition, the new M7 also introduces excellent intelligent parking capability, which enables vehicles to easily identify various parking spaces and realize automatic parking through innovative technical means, so that users are no longer subject to parking difficulties when driving in cities.

A smart cockpit that breaks through the boundary, Smart Cockpit 3.0 makes travel more convenient.

The smart cockpit of the new M7 is also one of the highlights that will lead to future travel. HarmonyOS Intelligent Cockpit 3.0 brings a creative and interesting interactive space for users. First of all, many people admire the fluency of the HarmonyOS car machine system, which makes users feel like they are in a virtual world full of science and technology and interest during driving, especially with the blessing of Xiaoyi’s intelligent assistant, which makes the intelligent interactive experience more advanced and allows drivers to interact with vehicles more conveniently, which not only improves the convenience of operation, but also brings more entertainment for drivers.

The emergence of HUAWEI MagLink? smart car screen system is also a bright spot. It has reached the level of Huawei’s flat panel, realizing the smoothness of multi-screen interaction, making the car a flexible and ever-changing space, allowing drivers to have more possibilities in the car.

It is worth mentioning that HarmonyOS Intelligent Cockpit 3.0 can realize a series of functions, such as offline map voice navigation, which improves the practicality to a new height and makes travel more convenient. Through the support, the car has also achieved a smooth conversion with various applications in Huawei mobile phones. Whether you are chasing a drama or playing a game, users can connect seamlessly after getting on the bus and enjoy a more coherent and intelligent interactive experience.

Intelligent safety leads, omni-directional anti-collision safety guarantees lead to new standards of travel safety.

In terms of travel safety, the new M7 is also very careful. The world’s first omni-directional anti-collision system of HUAWEI ADS 2.0 installed in the car can provide users with all-round safety protection. With the help of multi-sensor fusion sensing capability based on lidar, HUAWEI ADS 2.0 has achieved omni-directional anti-collision capability in forward, lateral and backward directions, providing an efficient and accurate collision warning and response mechanism for vehicles. The system can not only identify common obstacles, but also identify road boundaries, so that vehicles can adapt to the changing driving environment more intelligently.

It is particularly noteworthy that in the AEB active safety evaluation of Autolab, the new M7 in the world won all kinds of active safety evaluation champions with HUAWEI ADS 2.0, which shows that its safety performance is high, and it can also stop in time when it participates in the evaluation at 90km/h at night, which also gives feedback on the strength of the new M7 in the world.

At the M9 and Huawei Panorama Conference, it was mentioned that the brand-new super smart factory, with more than 1,000 intelligent devices, 100% automation and integrated die casting process, has the highest production efficiency in the world and a new car is rolled off the assembly line every 30 seconds. With its excellent strength, Wenjie is becoming a leader in the new energy large SUV market, and its "three-intelligence ceiling" strength has been confirmed in many ways. This is not only a car, but also a future journey of intelligence, safety and innovation. I believe that in the future, the new M7 will be able to win the favor of more consumers.

Huawei Changan launched in-depth cooperation, and Aouita earned CHN model evolution empowerment.

At present, the competition of smart electric vehicle track in China is fierce, and the emerging brand Aouita can stand out from it without the deep empowerment of Changan Automobile, Huawei and Contemporary Amperex Technology Co., Limited. Recently, Huawei and Changan Automobile have carried out in-depth cooperation, focusing on the R&D, production, sales and service of intelligent driving system and incremental components of intelligent networked vehicles through the establishment of a new company by Huawei and the shareholding of Changan. In the future, Aouita will give priority to the technological advantages of the new company and accelerate its step towards an international high-end smart electric vehicle brand.

It is reported that after the establishment of the new company, Huawei will integrate the core technologies and resources of the smart car solution business into the company, and Changan Automobile, as an investor, will join hands with Huawei to support the future development of the company. The company is committed to becoming a world-class leader in the automotive intelligent driving system and components industry, and cooperates with partners to jointly promote the upgrading and development of smart car technology and industry.

As early as before this cooperation, Huawei and Changan had a close relationship. Together with Contemporary Amperex Technology Co., Limited, they jointly created a new generation of intelligent electric vehicle technology platform CHN, which is the industry leader. Based on this platform, Aouita has successively launched "Emotional Intelligent Electric SUV" Aouita 11 and "Future Intelligent Luxury Car" Aouita 12, bringing users a more technological, advanced and superior product experience.

Specifically, Aouita 11 is the first flagship model of Aouita, which is equipped with HI Huawei’s full-stack smart car solution. It has excellent intelligent driving ability and excellent mechanical quality, and can bring users a better travel experience. It is worth mentioning that Aouita 11 is the first automobile brand in the world to reach Mount Everest by intelligent driving, which is truly out of the circle in the industry and has attracted the attention of many users. In November this year, Aouita 11 delivered 4,080 units, actively implemented the brand promise, and accelerated the response to users’ expectations.

Aouita 12, the second flagship model of Aouita, has three characteristics of "top design, top luxury space and top intelligence", and its comprehensive strength is far ahead of its peers, setting a new benchmark for luxury smart electric vehicles in the world. On November 10th, Aouita 12 officially announced its global listing. In the first month of listing, the number of large orders exceeded 20,000, and the market was very hot. The future is expected.

It can be seen that Changan Automobile and Huawei have a good foundation for cooperation. This time, the two companies will join hands to set up a new company, which will promote the further innovation and evolution of CHN model. In this context, Aouita is expected to enjoy the priority of its new company’s brand-new technology, and create a "top-flow" travel experience for users with top-notch technology.

Chinese Express’s first domestic mass production L4 fully independent parking service successfully landed and put into trial production.

  Economic Daily-China Economic Net September 14th Recently, Chinese Express announced that the L4 fully autonomous parking service system (AVP) has been developed in Shanghai, and it has been tested and put into trial production on the high-tech HIX production vehicle. This is also the first domestic L4 fully autonomous parking service system based on vehicle-road coordination on mass-produced electric vehicles, which indicates that the research and development of intelligent electric vehicles in China is in a leading position in the world in the advanced technology field of autonomous driving. Ding Lei, Chairman of the Board of Directors, said that Chinese Express always starts from the dimension of users’ travel, stands at the forefront of autonomous driving, takes users’ safety as the premise, comprehensively improves the overall efficiency of traffic travel, and truly promotes the mass production application of autonomous driving and vehicle-road coordination technology in a wider range.

  AVP(Automated Valet Parking) is an L4 high-order automatic driving system based on vehicle-road cooperative development. Roadside sensing devices such as laser radar and communication and calculation devices are pre-built in the parking area to realize the identification and tracking of vehicle position and surrounding obstacles, and the dispatching information, vehicle positioning, obstacles and other information are sent to the vehicle through the cooperation of 5G vehicles, and the vehicle automatically drives into the parking space. The owner got off at the parking area, and the vehicle drove into the parking lot and parked in the parking space. The vehicle can also be started through the APP, automatically driving out of the parking space and driving to the location specified by the user.

  AVP can overcome the difficulties that bicycle intelligence is difficult to solve, such as no GPS positioning signal in the parking lot, too many turning shades, and large sensor blind area, so that HIX has the most reliable fully autonomous parking function at present. It is reported that HiPhi X, the first intelligent electric vehicle owned by Chinese Express, which will be listed at Beijing Auto Show, will be equipped with this technology, and it will become the first intelligent electric vehicle in China to realize L4 autonomous parking in mass production, creating a new era for the development of intelligent electric vehicles in China.

  In addition to AVP, the HiPhi X autopilot system equipped with HiPhi Pilot is the only dual redundancy system equipped according to the principle of aircraft safety design. The vehicle can start, stop, turn and walk in the full speed range of 0-130km/h, so that the feet can be separated, the hands can be put down and the eyes can be moved; Through the joint action of 24 sensors (including intelligent forward-looking camera, panoramic camera, millimeter-wave radar, ultrasonic radar, DMS camera for driver status detection, etc.) and high-precision maps, the L3-level automatic driving level of bicycles is realized, and it is also the first mass-produced vehicle in China to reach L3-level at present.

  In 2019, Chinese Express opened the world’s first intelligent road for coordinated autonomous driving in Yancheng, Jiangsu Province, and opened the "Smart City" demonstration project for the integration of 5G roads and cities in Zhangjiang Artificial Intelligence Island. The realization of autonomous parking service is another successful landing and application of roadside perception, cloud scheduling and vehicle control put forward by Chinese Express in the field of automatic driving based on the "three intelligences" strategy of smart cars, smart transportation and smart cities, and it will be extended to smart travel fields such as smart parking lots and smart highways in the future.

Fire! Ballets russes danced "Swan Lake" in Zhejiang and then "Subject 3"

  With both hands thrown and feet twisted, the most popular dance at present is "Subject III", which not only caught fire on social media in China, but also attracted many foreign professional dancers to learn to dance.

  On the evening of January 2nd, Russian Tchaikovsky Ballet presented a performance at Deqing Grand Theatre. After the classic ballet Swan Lake, the actors skillfully danced the curtain call of "Subject III", which not only made the audience laugh, but also screened the circle of friends.

  Tide journalists noticed that before that, the Royal Russian Ballet and the world Latin dance champion Christina also performed "Subject 3" in public.

  "Ballet+Subject 3", what is this "cross-border" linkage? How do they relate? On January 3rd, Chao journalist contacted Filippova Polina, head of Russian Tchaikovsky Ballet. The dance troupe has left Deqing and is preparing for the performance in Lu ‘an, Anhui. Before the performance, Filippova Polina was interviewed by Chao journalists through translators.

  "Subject 3 is also very popular in Russia, so we all jump." Filippova Polina said that "subject three" is now the "subject three" in the world, and the rhythm sounds very happy.

  Filippova Polina said that there are two reasons for the curtain call of "Subject 3": First, I want to make a "reversal" at the end of the performance, ending with a cheerful song with the most popular dance, so that the atmosphere at the scene will be more enthusiastic and the audience will leave in joy; Secondly, it’s also a way for Russian ballet companies to express their friendship. They want to thank the audience in China. They danced "Subject 3" in China "when in Rome". I hope everyone will also like Russian ballet.

  "In everyone’s cognition," Swan Lake "is an elegant art, and" Subject III "is a popular art. Both of them are performed by the same group of dancers on the same stage, and the response on the spot is particularly good." Zhou Wangqiang, director of the China Performing Arts Association and deputy secretary-general of Zhejiang Performing Arts Association, said.

  Zhou Wangqiang revealed to Chao News reporter that "Subject 3" is actually an "optional action", and the ballet company will communicate with the theater in advance whether it will be used as a curtain call. "It is not necessary to use this curtain call every time. It is a’ blind box’ for the audience, and it is really not necessary to see it."

Who is tomoji? Where did you come from and where did you go?

After attending the Zhiji auto conference, I posted some pictures of new cars on social media and immediately received a user comment: "Buying a car these days is the same as buying a mobile phone." What this user actually means is that the current car is updated quickly and dazzled.

 

 

Through this topic, we go deep into the perspective of industry. What is happening in the automobile industry is also very similar to the development path of smart phones. In addition to the historic event that Apple defeated Europeans, China’s mobile phone industry has also become the most important pole in the world, and its brand image and core technology have made rapid progress. Huawei even made its own various core chips. Today, it used to be considered as an insurmountable operating system, and Huawei also used the HarmonyOS operating system to announce that we had turned over this mountain.

 

Under the background that cars are becoming smarter and more electrified, the whole industry is similar to the smart phone industry in the past, but the wheelbase of time is not long enough. Maybe looking back 10 years later, this feeling will be more profound.


Let’s focus on the present. The number of new automobile brands in China is unique in the world, and those traditional automobile manufacturers are also trying to build higher-end new brands, polish more eye-catching new products and start the horn of having more core technologies through this historic opportunity of change. Last month’s case was Dongfeng Motor, which launched Lantu, and this month’s case was SAIC, which pushed Zhiji to the stage.

 

Who is tomoji?

 

 

Strictly speaking, Zhiji is not unique to SAIC, but a new brand jointly created by SAIC, Alibaba and Zhangjiang Hi-Tech. As a newly established brand, you may still be unfamiliar with it.

 

Zhiji, which reads "self". Why take such a name? According to the official, Zhiji is taken from The Book of Changes, "Knowing everything is around, but Dao Ji is under the world", aiming at understanding everything with wisdom, diligently exploring, defining, creating and realizing the smart travel driven by the times and needed by users.

 

We can simply understand that intelligence represents intelligence; Represent oneself, alsonamelyUsers.If you read their introductions in the official media of Zhiji, you will definitely see what cars should look like in the intelligent age."This sentence.In addition to the three major shareholders, 4.9% of Zhiji’s shares will be built into a user rights platform.Therefore, Zhiji is a condensation of the two visions expressed by this brand.

 

 

Zhiji’s English brand name is "IM", which is the same as the Chinese name. Besides, purely for fun, the name IM is attractive, at least it will make people think of the iPhone.

 

The user rights platform is heavy enough, so it goes without saying what users participate in product design.

 

Where is the intelligence?

 

Is Zhiji really smart? Zhiji’s speed is fast enough. On the 13th, Zhiji has released two new cars, a car and an SUV, all of which have not been officially named, and they have no names when they are unveiled. Presumably, the naming of new cars that are still brewing inside must also have strong characteristics. Cars will be accepted during the Shanghai Auto Show in April, listed at the end of the year, and delivered to users in 2022. The progress of SUV is a little late, but it will also be listed in 2022.

 

Through specific models, let’s look at the intelligence of Zhiji.

 

 

Zhiji’s car is equipped with intelligent lighting system, which is composed of 2.6 million pixels DLP and 5,000 LED ISC, and can realize V2X driving fusion interaction and intelligent lighting expression. Specific functions, first, smart lighting navigation; Combined with high-precision map and navigation road planning, the next route can be guided by changing lights.

 

The second is Spot light pedestrian reminder; The infrared and visual fusion perception system of the whole vehicle is integrated to help pedestrians predict traffic risks in advance, for example, the number of seconds of traffic lights can be displayed on the lights. Third, the width-indicating optical blanket guidance; It means that the new car can recognize the road narrowing condition, automatically trigger the width-indicating light carpet in advance, and can automatically adapt to the lane line to draw the light carpet.


Fourth, the wisdom light moves with the eyes; Tracking the eyeball orientation through the camera in the car, and controlling the direction in which the headlights illuminate the driver. In addition, the smart lighting system supports flexible and personalized OTA, allowing users to design freely and enhance interest.

 

 

Zhiji’s car is equipped with an image sensor with 150 million pixels as a whole, which supports 180 distortion-free ultra-wide-angle, 4K high-definition video shooting, super night scene, high dynamic range, time-lapse photography, slow-motion photography and other modes. Videos can be edited and shared to social media with one click, and can be connected to major live broadcast platforms to broadcast live from the first perspective, and professional photography templates are provided.


This system is called Carlog, and it is extremely fresh. In the future, Kaizhiji’s car can easily record the picturesque scenery and cultural stories passing by and share them conveniently.

 

 

The eye-catching 39-inch huge display screen in the car can be intelligently lifted and lowered according to the usage scene, and there is also a 12.8-inch 2K AMOLED curved central screen on the lower side; Inside the screen is Zhiji’s IMOS system.

 

With the screen group full of science and technology, IMOS system has three characteristics, which are flowing, moist and pure. These three elegant words refer to multi-screen display respectively; Based on the weather, time, road conditions, and even based on the user’s mood, users are recommended in different scenarios; Only some necessary intuitive information is presented when driving. Sounds good? At least it aroused our strong curiosity and looked forward to the real experience.

 

From now on, charging will be intelligent. Zhiji’s car will be equipped with 11 kW high-power wireless charging for the first time in the world. It is said that the charging efficiency is almost the same as that of traditional charging, and it can charge 10.5 kWh in one hour, which is equivalent to 70-80 kilometers of battery life according to NEDC working conditions.

 

 

These intelligent abilities are relatively innovative. Then, to what extent has Zhizhi achieved the intelligence in the automatic driving ability that the industry is competing for at present?

 

The first model, namely the car, will be equipped with the NVIDIA Xavier computing platform with a computing power of 30-60TOPS, and the integrated sensing solution of 15 high-definition visual cameras, 5 millimeter-wave radars and 12 ultrasonic radars, as well as the algorithm developed based on the characteristic road conditions and driving habits in China, will form the whole system of automatic driving.


From the hardware point of view, the ability of this system is in the first-class level at present. However, the new car will be delivered in 2022, when Weilai ET7 with stronger book strength will also be delivered.

 

 

Zhiji has also considered a more radical scheme to provide new cars with upgrade redundancy in a compatible way. At present, it is not clear whether the redundant system can be installed after installation or introduced in the form of a modified model.

 

The key upgrades of this redundant system are lidar and NVIDIA Orin X chip. It is exaggerated that the number of lidar will reach three; NVIDIA Orin X chip and weilai ET7 use the same model, and the computing power will soar to 500-1000+TOPS.


As for the time point, the official said that the lidar will enter the mature stage of commercial mass production, and Zhiji Automobile will be upgraded immediately. Considering that Weilai plans to deliver ET7 equipped with lidar to users in 2022, Zhiji’s speed should not be too late.

 

 

As for the specific actual experience, the news given by Zhiji be The functions of the automatic driving system include memorizing parking and calling cars, automatically parking service and calling cars, traffic light recognition, automatic crossing, traffic jam prevention, automatic obstacle avoidance, automatic lane change, overtaking, getting on and off ramps according to the navigation path, and rear-end collision alarm.With the permission of national laws and regulations and the opening of high-precision maps, by the end of 2021, wisdomone’s ownThe car will have the ability to take over the automatic driving from point to point.

 

Zhiji focuses on automatic parking service and wake-up car. This function allows users to get off the bus and let the vehicle automatically parking service through the mobile APP; When picking up the car, the car will automatically park out of the parking space and drive to the designated location to facilitate the user to get on the bus. By the end of 2021, the functions of automatic parking service and calling cars will be applied in certain commercial centers in first-tier cities.

 

 

In 2022, it will gradually expand to specific supermarkets in first-tier and new first-tier cities. This function is quite beautiful when you think about it. After a year, the new car is delivered and you can drive Zhiji’s car to a specific shopping mall, so you can save the trouble of finding a parking space. I have to say, the development of technology is really fast. Of course, the premise is that Zhizhi can accomplish his goal on time.

 

In addition, the actual experience of the autopilot system, we have to wait until 2022 to get the answer, that is, it is not really that smart.

 

How is the performance?

 

Intelligence must be the most important ability of future cars, not power and endurance. Power and endurance in the future, everyone should do the same. Therefore, it is rational for Zhiji to focus on intelligence. Having said that, the new car released by Zhiji is also excellent in terms of power and endurance.

 

 

The new car is equipped with front and rear dual motors, and the rear axle motor is the main driving source. The total maximum power is 400 kW, and the torque is 700 Nm, which is slightly less than that of Weilai ET7, but the acceleration time of 100 kilometers is consistent with it, only 3.9 seconds.

 

Standard 93 kWh battery pack, with 115 kWh battery pack; Although the semi-solid battery technology adopted by Weilai ET7 battery pack is not adopted, it is also the first in the world to use silicon-doped lithium-supplementing technology, which realizes the ultra-high energy density of 300 watt-hours/kg, and can support Zhiji’s car to reach the battery life of nearly 1000 kilometers.

 

You don’t have to worry about the ability of the chassis. The new car is equipped with an all-aluminum chassis with a front double wishbone and a rear five-bar suspension, a brake-by-wire system, an AKC rear wheel steering system by wire, and a CDC intelligent electronic control suspension system, and the key adjustment is the responsibility of Williams professional chassis adjustment team from one of the three F1 teams.

 

 

It can be said that Zhiji represents the peak of SAIC’s strength.

 

Can the future be expected?

 

The emergence of intellectual self is aptly described by being in the right place at the right time. Tianshi refers to the intelligent and electrified industrial transformation, which represents the opportunity to change lanes and overtake into the high-end market; In addition, after years of development, the industry has reached a critical point of technological leap, and the infrastructure construction is also improving day by day. It seems that Zhiji’s admission is late, but it just happened to catch up with the good opportunity.

 

SAIC’s own brand has gained sufficient technical foundation and experience in various aspects through its development in the low-end market in the past, and SAIC itself is also quite rich, which is the geographical advantage of Zhizhi itself. People and better understanding, the background and resources that Alibaba and Zhangjiang Hi-Tech can bring need not be said.

 

 

When I came out of Zhiji’s release venue, Shanghai Tower, the tallest building in China, and looked up at this 632-meter symbol of China’s economic take-off, I couldn’t help feeling again that, like the smart phone industry, China will surely make breakthrough progress in the future of the automobile industry and become the most important pole in the world.


And the new intellectual will witness this process; And what is its own fate? After reading our introduction, what do you think of it?

Xiaokang shares were investigated by 87 institutions: only about 8,000 SF5s were delivered in 2021, and the reason for the small delivery was mainly due to chip problems (with survey questions and ans

  () The Record Form of Investor Relations Activities was released on January 8th, and the company was investigated by 87 institutions on January 7th, 2022. The types of institutions are QFII, insurance companies, others, fund companies, overseas institutions, securities companies and Sunshine private equity institutions.

  The main contents of investor relations activities are introduced:

  First, introduce the company’s situation. Xiaokang and Huawei create a new model of deep cross-border cooperation in joint business. On April 19th, 2021, we started a mobile phone shop to buy cars. On December 23rd, Huawei released a new mobile phone and our new car at the same time, which was the first time that two smart terminals, a mobile phone and a car, were released at the same conference. The conference was a great success. It cooperated with Huawei and has a strong online digital marketing channel, especially in the core business district, which has a large number of offline store resources and is convenient for users to reach. We pursue quality delivery, adopt experiential marketing, and adopt a new sales model based on our vast offline store resources, which has a good response and strong customer purchase intention. We think this new sales model is the development trend of intelligent electric vehicles.

  Second, explain the company’s current hot topic in the market (1) Xiaokang initiated a new model of joint cross-border cooperation.

  On the question of whether Xiaokang is a foundry, we made it clear that we didn’t do it before and now, let alone a foundry. Eighteen years ago, before we entered the automobile industry, the cooperation with Dongfeng Group realized the first successful cross-border of Xiaokang shares, and Xiaokang shares did not work as a foundry. According to the strategic agreement, joint business cooperation agreement and related agreements signed by us and Huawei, we and Huawei are long-term partners. From R&D to manufacturing to delivery of automobile business, the company is responsible for R&D, manufacturing, delivery, service and creating user experience in the whole life cycle; Huawei is deeply involved in product definition, quality control and channel sales.

  The cross-border cooperation between Xiaokang and Huawei is deeply successful. The teams of the two sides have worked hard day and night and invested huge manpower and resources. Now and in the future, there is no reason for the two sides not to cooperate.

  (2) Regarding whether SF5 is discontinued:

  SF5 and Wujie M5 are both models of Celestial Company, and the company will continue to introduce new models to meet the needs of more users. As far as the company is concerned, we will not take the initiative to stop production. As long as users have demand, we will produce and deliver it. That’s the case with SF5. We will not take the initiative to stop production. The price of SF5 and Wujie M5 are different, so users can choose. We give the choice to users! Orders will be produced, delivered and served, and Cyrus will serve every car and every new and old user! Whether SF5 or M5, we will achieve high-quality delivery.

  (III) Question and answer session of investors

  Q: A new model of cooperation between Huawei and Xiaokang emerged at the end of the 21st century. Can you introduce the cooperation model in detail and how to learn from each other’s strengths?

  A: The cooperation with Huawei is cross-industry cooperation. Huawei Terminal Company is well aware of customer needs. As a mature vehicle enterprise, Xiaokang has experience in automobile research and development, manufacturing, sales and service. The cooperation between the two parties has created a precedent in the industry and produced a lot of valuable experience. This model is also the development trend and future of the smart electric vehicle industry, and it has also achieved some success. Before Xiaokang was engaged in automobile and () cooperation, Xiaokang shares crossed the border into the field of micro-cars. Since we entered this industry in 2003, there were many friends, and now there are only three enterprises left in that year: Wuling, Changan and Xiaokang. This shows that we have experience in cooperation with other enterprises, and we also have a successful experience base. Xiaokang is a modern private enterprise with high efficiency. The cooperation with Huawei over the past year has also proved the success of an efficient and standardized private enterprise mechanism. We launched a new model in March last year, and everyone saw our M5 debut in December last year. I believe that the effect of cross-border cooperation will begin to be reflected in the first quarter of this year, and batch delivery will begin in March this year. We are very confident about the sales data in the second and fourth quarters.

  The monthly sales target of the new energy automobile industry is over 10,000 yuan. We think this is the threshold sales volume of new energy vehicles in 2022, which is our goal, and the threshold sales volume will be higher in the future. At present, it usually takes a certain time for the sales of high-end electric vehicles to climb. We have full confidence and confidence in our products and channels, and hope to achieve the sales scale achieved by others in five or six years within two years.

  Q: The delivery volume of SF5 last year was less than the market expectation. What did the company think?

  A: Only about 8,000 SF5s were delivered in 2021, and the reason for the small delivery was mainly due to chip problems. The chip will affect our delivery mainly because our owner of SF5 is developed in the United States, so he uses more American electronic materials, which has been greatly affected.

  Q: Can you tell us about the follow-up vehicle planning?

  A: We have now launched the M5, and it is expected that a new large SUV will be launched at the end of the second quarter or the beginning of the third quarter in the middle of the year. I’ve been driving the M5 myself for some time, and I’m confident that it’s a car that can’t be separated once I get started. We are also developing a new large-size SUV, which will be released in 2023.

  Q: What is the pace of the subsequent launch of pure electric vehicles?

  A: There will be pure electric vehicles coming out this year. Because in 23 years, Shanghai’s extended journey can’t get a green card. Considering these market demands, we will have a pure electric version of M5.

  Q: When will the M5 be officially delivered? What is the output scale?

  A: There will be small batch delivery in February, and batch delivery will start in March. Wenjie M5 is mainly produced in Liangjiang Factory in Chongqing, which can produce 30 sets per hour, and its automation efficiency is still very high. This factory can produce 15,000 units a month. The models in the second half of the year will be produced in another factory in Chongqing, which will not affect the production capacity of M5.

  Q: Will Huawei cooperate with other car companies?

  A: Although it’s not up to us to decide who Huawei will cooperate with, our cooperation is already deep. As mentioned earlier, Xiaokang Co., Ltd. is a modern private enterprise, and its efficient and flexible mechanism is our advantage, so it is difficult for other manufacturers to reproduce it in a short time. Our cooperation is our common choice.

  Q: Why is Huawei’s self-driving system not reflected in the M5? Will it be reflected in subsequent models?

  A: Huawei’s autopilot is different from Tesla’s autopilot. Huawei’s auto-driving is vehicle-road coordination, which requires vehicle-road coordination. Without road coordination, the auto-driving of the car cannot be played out. Tesla’s auto-driving is self-adaptive auto-driving, and the road is only an aid. The contents of China’s road regulations on autonomous driving are still under study, and we also hope that China’s roads will be opened to autonomous driving as soon as possible. Auto-driving vehicle-road coordination is not only to ensure that my car does not hit the wall, but also to ensure that other people’s cars do not hit me. This high-order auto-driving technology of vehicle-road coordination is very advanced and needs time data verification. Our follow-up models will definitely have Huawei’s advanced autonomous driving.

  Q: What do you think of the present integrated die casting technology? Will you consider using integrated die casting technology for any vehicle model in the future? Is there a die casting factory or die casting machine factory in communication?

  A: It is expected that from the end of this year to the first half of next year, we will realize integrated die-casting body. Now it has entered the stage of comprehensive research and development. This technology will reduce the weight of the car body and increase the output. Because at present, the front section and the rear section are provided for welding, the technology will be integrated aluminum alloy die casting, which will greatly improve the production efficiency;

  Chongqing Xiaokang Industrial Group Co., Ltd. is a manufacturing enterprise integrating R&D, manufacturing, sales and service of passenger cars, commercial vehicles, powertrains and other automobile parts. The company currently has complete vehicle brands such as SERES, Dongfeng Scenery, Dongfeng Xiaokang, DFSK, Ruichi, etc. The main product pedigree includes SUV, MPV, mini-car and core parts. Among them, the whole vehicle products cover intelligent electric vehicles and fuel vehicles, and the core components include powertrain and three electric products with displacement from 1.5t to 2.0t..

AITO asked the M7 declaration map to be exposed, with its own Huawei system, and the arrow is on the line!

At the end of last year, Celeste and Huawei officially released the AITO Jiejie brand, and then launched the brand’s first model, the Jiejie M5. This year, Huawei officially launched the new model, the Jiejie M7 again. Recently, the M7 declaration map was exposed, and it was also positioned as a medium and large SUV, which had a slight collision with Li ONE in the same model. Let’s take a look at the works of the big brother in science and technology in the automobile industry.

In terms of appearance, most of the design elements of M7, including inverted trapezoidal grille and penetrating taillights, remain the design of M5. The front and rear door handles of the new car are designed in a hidden way, which is also a popular design technique for new energy vehicles at present, creating an intelligent and scientific effect. The overall body shape is smooth and elegant, but it lacks some sense of science and technology compared with some new models on the market, and it has also been vomited by some netizens that the design is "too old-fashioned". Compared with Li ONE, it is more scientific and technological. It seems that the M7 is more suitable for business people who pursue large space or car owners who prefer calm models.

In terms of body size, the length, width and height of the M7 are 5020/1945/1775 mm and the wheelbase is 2820 mm, which is close to the body size of Li ONE. The new car will also adopt the 6-seat layout of 2+2+2. After all, in the new energy market, large-size 6-seat SUVs are still very popular. However, Li ONE, as the biggest competitor of the M7, is also a 6-seat large-size SUV of the new energy model, and its size is extremely close. I wonder if it will be affected. In addition, the rear row of the new car is also designed with a rear privacy glass configuration to make the car more private.

In terms of power, the M7 is a hybrid electric vehicle equipped with h15rt 1.5T four-cylinder extended range engine. The maximum power is 92kW, and the fuel consumption of engine wltc is 1.05l/100km. Li ONE is also equipped with an extended-range hybrid system, which consists of a 1.2T engine and a brand-new drive motor, and is equipped with an ideal self-developed Li OS system and a millimeter-wave radar with driving assistance. Although there is no official data on battery capacity and battery life, the battery life of M7 will not be weaker than that of Li ONE, and the power system is really hard to tell.

At present, the interior of Wenjie M7 has not been made public, but it is understood that the new car will adopt the simple scientific and technological style similar to Wenjie M5, full LCD instrument and an oversized central control panel, and it has a built-in HarmonyOS OS intelligent cockpit. Presumably, its powerful ecological function will also bring different surprise experiences to Huawei’s new and old users.

From the price point of view, it is estimated that the selling price of M7 will be above 300,000, while the guiding price of Li ONE is around 349,800. If M7 can be lower than this selling price, the competitiveness will be more imaginative.

Although the official has only released the appearance and some dynamic information at present, judging from these data and the performance of M5, the launch of M7 is still worth our expectation. After all, it is a brand launched under the leadership of Huawei with strong scientific and technological strength. Let’s wait and see.

Where is the difficulty in mass production of solid-state batteries?

    Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. However, at present, all three technical routes have corresponding basic shortcomings that need to be solved urgently, and the cost is also an insurmountable hurdle for enterprises.

  Toyota Motor Corporation recently announced at the technical briefing that it has found good materials to commercialize solid-state batteries from 2027 to 2028 and put pure electric vehicles equipped with all-solid-state batteries on the market. However, because Toyota did not publish convincing technical details, it caused public opinion to question.

  Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. Thirty years ago, Oak Ridge National Laboratory claimed to have built a solid-state battery, but it is a pity that it has not been mass-produced so far. In the past two years, with the popularity of new energy vehicles around the world, many companies have reported the progress of mass production of solid-state batteries, but after the news was exposed, there was no more.

  According to the material system, solid-state batteries can be divided into three technical routes. Japan and South Korea are betting on sulfide systems. In Europe, the main route is polymer, while in China, the main route is oxide. Among them, Japanese and Korean companies, represented by Toyota, Samsung SDI and Hitachi, have profound technology accumulation and obvious first-Mover advantage, and the trend of joint research and development is obvious. However, these three technical routes all have corresponding basic shortcomings that need to be solved urgently.

  Specifically, sulfide electrolyte has poor air stability, and when it is exposed to air, it will produce toxic gas. At the same time, with the destruction of electrolyte structure and the attenuation of electrochemical performance, the synthesis, storage, transportation and post-treatment of sulfide electrolyte need to rely heavily on inert gas or drying chamber. At room temperature, the ionic conductivity of polymer electrolyte is low, which makes the charging of polymer solid-state battery need to be completed in high temperature environment, which greatly limits its commercialization. Most oxide electrolytes have wider electrochemical stability "window" and better oxidation stability, but in order to ensure good interface contact between rigid oxide electrolytes and cathode materials, it is often necessary to sinter at high temperature, otherwise it will lead to serious interface chemical side reactions. In addition, some oxide electrolytes also have the problem of lithium dendrite growth.

  At the same time, cost is also a difficult hurdle for enterprises to overcome. At present, the cost of semi-solid battery is much higher than that of commercialized liquid battery. According to industry research and calculation, taking NCM811 liquid battery and NCM811 semi-solid battery as examples, the cost of semi-solid battery increases by about 80% compared with that of liquid battery. Among them, the cost of solid electrolyte is the main new cost and the main cost in semi-solid battery, accounting for about 50%. Due to the change of electrolyte material, production process and lack of experience in product quality control, the cost of all-solid battery is higher than that of semi-solid battery.

  There are five main indicators to measure whether a power battery can be mass-produced, namely, energy density, charge-discharge rate performance, cost, safety and cycle life. The laboratory research results of power batteries generally make a major breakthrough in one or several indicators at a certain stage, and it is possible to mass-produce them only when they meet the requirements of five indicators. In other words, as far as the current research and development progress of major enterprises is concerned, solid-state batteries seem to be "windy", but in fact they are "long and long", and the mass production is still quite difficult.

  Compared with structural innovation, the improvement of battery materials is slower and indeed more difficult. However, being difficult does not mean not doing it. We often say that it is reasonable to do the "difficult and correct thing". From the perspective of technological change, the technological innovation of power battery has played a major role in promoting the development of automobile electrification. The reason why China’s new energy automobile industry can lead the world is that we have surpassed the power battery, and a global power battery giant like Contemporary Amperex Technology Co., Limited was born.

  In the industrial transformation driven by the goal of "double carbon", the innovation of power battery has become the key to strengthen the competition level of new energy vehicles, build the national industrial competitiveness and stabilize the competitive advantage of enterprises. Whether it is the first country or the catch-up country of new energy vehicles, or the main enterprises of the power battery chain, they are all aiming at new technologies and laying out solid-state batteries. This is both a great challenge and a rare opportunity. Super-large-scale market advantage, leading industry-wide competitiveness and rising innovation make China more qualified to win the strategic commanding heights of power batteries.
