Great Wall Motor donated a pickup truck with a total value of 1.5 million yuan to help Sichuan earthquake-stricken areas.

  Recently, an earthquake of magnitude 6.8 occurred in Luding County, Ganzi Prefecture, Sichuan Province. The disaster situation touched people’s hearts. Great Wall Motor urgently donated 2 million yuan worth of money and materials to help Luding County, Ganzi Prefecture, Zichuan, Shimian County, Ya ‘an City and the surrounding disaster areas. Among them, the Great Wall pickup truck with a total value of 1.5 million yuan was donated to the China Red Cross Foundation for disaster relief materials transportation, emergency rescue in disaster areas and support for subsequent reconstruction.

  After the earthquake, roads were blocked due to landslides, gravel rolling and other reasons, and some roads became narrow and impassable. In the section where big trucks are difficult to pass, pickup trucks donated by the Great Wall can transport materials to the disaster area, support post-disaster reconstruction and enrich the shortage of local rescue vehicles by virtue of their strong passability, ability to get rid of difficulties and loading.

  The Great Wall pickup truck will also pay close attention to the progress of post-disaster rescue and tide over the difficulties with the people in the disaster areas.

  Rushing for disaster relief, empowering public welfare rescue standardization

  All along, Great Wall pickup truck has been actively practicing public welfare and shouldering corporate social responsibility while developing itself.

  Last year, the "7.20" torrential rain in Henan Province, the National Motorists’ Association of the Artillery Alliance gathered overnight, and more than 200 Great Wall cannons rushed to Henan for disaster relief, opening a life channel for more than 4,000 Zhengzhou residents. At the same time, the Great Wall pickup truck acted quickly and launched eight care policies to provide all necessary protection and services for the affected car owners and minimize vehicle losses.

  More than that, Great Wall Artillery also established the first public welfare rescue college in the industry, and launched a centralized training camp focusing on solving the actual rescue situation, aiming to stimulate the enthusiasm of Great Wall artillery riders to participate in public welfare rescue, and also to make public welfare rescue professional and standardized, so that every rescue is awe of life.

  At present, the Great Wall Gun Public Welfare Rescue College has graduated more than 110 users, greatly improving the practical skills of public welfare rescue and empowering users to standardize public welfare rescue.

  Climbing Mount Everest to protect the scientific research and help the national task

  In addition to in-depth rescue in the disaster area, the Great Wall Gun also climbed Mount Everest, crossed the desert and escorted the national scientific research with users.

  In the activities of measuring Mount Everest for three consecutive years, the Great Wall Gun in 2020 helped the country successfully complete the guarantee task of Everest elevation measurement; In 2021, the Great Wall Cannon, together with more than 300 car owners and 120 Great Wall Cannons, stood the test of rain, snow, fog and other complicated weather and gathered at the foot of Mount Everest. In 2022, the full-line pickup truck model of the Great Wall Gun once again successfully arrived at Everest Base Camp to pay tribute to the spirit of climbers.

  The Great Wall Artillery also escorted the successful completion of the scientific research task of Lop Nur, China Academy of Forestry. As the official vehicle for scientific research tasks, the Great Wall Gun, with its all-terrain off-road performance and towing rescue capability, broke through the harsh natural environment, escorted the scientific research workers all the way, ensured the successful completion of the national scientific research tasks as planned, and also contributed to wildlife and ecological environment protection.

  Persist in caring for students and shoulder the responsibility of people’s livelihood

Zhiji Automobile and MasterGo: Follow the trend and cooperate with wisdom.

Zhiji Automobile is a brand-new user-oriented automobile science and technology company jointly built by SAIC, Zhangjiang Hi-Tech and Alibaba Group, which was established in 2020. As the implementer of travel change in the intelligent era, Zhiji Automobile is committed to exploring more advanced intelligent driving solutions to create a better future travel mode.

For Zhiji automobile design team, the most important task is to bring a good experience to the interaction between people and cars through high-quality on-board human-computer interaction (HMI) design. Guan Chaoxiong, the software design director of Zhiji car cockpit, once said, "High-quality HMI design is one of the reasons why many consumers choose Zhiji. The rapid iteration of HMI design is inseparable from advanced design tools, and the characteristics of MasterGo, such as efficient collaboration and intelligent delivery, provide key support for us to realize the agile development of HMI design. Zhiji Automobile will also continue to bring more new experiences of intelligent driving to users in the process of deep creation with MasterGo. "

Smooth coordination, with an efficiency increase of more than 30%

MasterGo has fast response speed, many preset materials and rich community resources, and soon spread in the design department of Zhiji. Interaction and products have become the two most used teams. According to Zhou Pingxuan, the designer of Zhiji Automobile, the company highly recognizes the efficient collaborative work mode brought by MasterGo, which makes the communication between upstream and downstream of production, design and research become smooth and improves the overall design and development efficiency by 30%-40%.

The design of HMI is complex. It should adopt multi-sensory interaction mode, transmit and feedback information by visual, auditory and tactile means, and adapt to different application scenarios and environments. Therefore, the design file has many modules and versions. In the past, designers had to export the design draft first, then submit it to R&D for review, and then repeatedly take screenshots to make comparison and modification according to their feedback. After the modification, they had to re-transmit it. Only the time for exporting, uploading and downloading files should be calculated by the day.

Nowadays, a link of MasterGo can solve the above problems. Project members operate in the same link, and internal collaboration and external sharing are extremely simple. When the design documents are changed, everyone will see the latest draft anytime and anywhere, and there will be no different versions of the documents. Computers and mobile phones can view them in real time, and the styles can be reused when the permissions are opened. When reviewing the design draft, if you have any suggestions, you can mark comments in the corresponding position through the comment function, and the designer can make targeted modifications and adjustments without waiting for the file transmission and editing process of traditional design tools.

"The most valuable thing about MasterGo is that it no longer needs a group of us to find a design element together, but can find what we need directly from the resource library." For example, to find a module component, in the past, it was necessary to find another module associated with this module and find the corresponding person in charge, and then the person in charge went to his own module library to find it, and so on.

In addition to greatly improving the team’s collaboration efficiency, Zhou Pingxuan also mentioned the advantages of MasterGo in system management and design assets. "The document presentation in the MasterGo workbench can also be set regularly, and every document can be followed. We can see that the whole process from 0 to 1, from birth to growth, can directly trace its source and improve the unity of asset management of the whole team."

Create an excellent HMI design system to enhance the product interaction experience.

Xiao Rui, the designer in charge of building the control library of Zhiji Automobile, believes that AIGC technology can quickly generate various design materials, but it is not suitable for HMI design scenarios. He explained that AIGC technology is more suitable for users who have a lot of marketing needs at the C end, and they often need to do a lot of banner or other short and fast promotional materials without too much refinement and personalization.

"The car model needs very high and accurate design. We have a special modeling department, which will render different interior decoration drawings according to different models. We have strict requirements for details such as light and texture. We need intelligence, but we are more focused and accurate. At this point, MasterGo meets our needs well." Xiao Rui said.

Xiao Rui also said that MasterGo’s support for control selection also brought them great convenience. He said that when calling controls, colleagues in the application team liked MasterGo’s control selection very much. It is not only convenient to adjust the control, but also has a variety of options. If you mark the properties, you can choose the style you need according to different parameters, which can greatly improve the design efficiency and consistency.

"For HMI design, we need to consider things from the system level rather than a single application level, so we emphasize unity and consistency. Unifying component libraries and design specifications in MasterGo is the basis for achieving standardized management. " Xiao Rui said. He believes that on the basis of standardized management, collaborative efficiency improvement brings designers more creative space. "This will allow us to have more time and energy to focus on innovating and optimizing HMI design, and bring better interactive experience to our users."

"Internal" worries about "external" troubles, and localization and migration follow the trend.

Internet product designers are no strangers to foreign collaborative design software. After the outbreak of supply interruption, the designers of Zhiji Automobile paid more attention to the security of design software and began to look for the optimal solution in domestic software.

When Xiao Rui talked about local design software, he felt that it would greatly slow down the efficiency of designers. For example, when the document versions of the sender and the receiver are different, updating the material library will automatically break the links of some controls; If you open the same file with different software versions, the layout will be misplaced and you can only reassemble the elements; If the file version update is not synchronized, the file transfer process will be interrupted for no reason, and it will be impossible to download after the time limit; Publishing new files must be exported and imported locally, and then manually downloaded and updated, which is a complicated and time-consuming process.

After comprehensively comparing the collaborative design software on the market, Xiao Rui decided to introduce MasterGo into the Zhiji design team. "Sketch to MasterGo has the highest degree of file restoration, and the overall migration cost of our team is very low." After the privatization deployment, the efficiency and professionalism of the MasterGo team made Xiao Rui firm his choice. "On one occasion, we put forward two requirements, one is to copy and paste as it is, and the other is to share files in HTM, PNG, PDF and other formats. The MasterGo team responded quickly and gave us a lot of positive feedback. No matter the product manager or the front-end developer, they were sincere and professional, and they helped us solve very difficult problems in the shortest time."

As an online product design tool to achieve "synergy and efficiency improvement", MasterGo’s increasingly excellent product performance and details exactly fit the brand connotation of Zhiji Automobile. It is simple and simple, which not only unifies the overall situation but also polishes the details, and is convenient and changeable. When asked about the expectation of MasterGo, the UED team of Zhiji Automobile believes that "online collaboration is bound to become the mainstream trend in the future, and learning and adapting to online collaboration tools is a skill that every designer must master. MasterGo is a tool, a platform and an opportunity. MasterGo has opened the door to China’s collaborative era and is gradually changing the way China designers work! "

Geely Raytheon Power DHT was copied from Chery because it was all in third gear? Official: We are different.

Recently, there are rumors that Geely Raytheon Power DHT technology copied Chery and registered the patent first. On August 2nd, the official account of Geely Network False Information Reporting Center issued a clarification, saying that the news on the Internet that "Geely Raytheon Power DHT technology copied Chery and registered the patent first" was seriously inaccurate, and the relevant content was wrongly quoted, which seriously damaged the reputation of Geely brand. The company has collected and fixed relevant evidence and reserved the right to investigate the responsibility of the infringer.

Geely issued a statement as follows:

1. The statement that "Geely hybrid car copied Chery car technology" in the online content is seriously inaccurate.

2. The part about "Geely 3-speed hybrid electric drive DHT Pro patent drawing (CN202120284735.7)" appearing in the network content is not a patent of Geely 3-speed hybrid electric drive DHT Pro scheme, but a patent of other Geely projects.

The domestic patent of Geely DHT Pro scheme (CN201810943518.7) was applied in August 2018 and published in January 2019; International patent (PCT/CN2019/078178) was filed in March 2019 and published in February 2020.

In addition, Geely’s 3-speed hybrid electric drive DHT Pro scheme uses the transmission of double planetary mechanisms+clutch+brake, and adopts two planetary gear mechanisms to realize different transmission ratios in the third gear of the power system, improving fuel economy and accelerating power performance of the power system. The planetary gear mechanisms realize different motion states to provide different transmission ratios through the combination or disengagement of the brake and clutch, which makes the power system not only simple in structure, competitive in cost, but also more adaptable. It is different from the transmission path of the "patent (CN201910360258.5) applied by Chery in 2019" quoted in the false content of the network transmission.

3. The statement that the patent nature of Geely DHT Pro is "utility patent" and "Geely dare not apply for invention patent" is seriously untrue. Geely’s DHT Pro technology has applied for an invention patent in August 2018, and our company has complete intellectual property rights for the patent of the 3-speed hybrid electric drive DHT Pro scheme. The patents of this scheme have been authorized in China, the United States and Japan, and the power products have been mass-produced by the end of 2021. The hybrid models of Xingyue L Raytheon Hi·F and Emgrand L Raytheon Hi·P have been delivered.

It is worth mentioning that this statement is the first statement analogy issued since the establishment of this account, which shows that Geely Automobile attaches importance to its power technology brand Raytheon Power.

According to the "Talk on Automobile Pulling", the reason why Raytheon hybrid technology was plagiarized was because both Geely and Chery hybrid transmissions used three gears, but the difference was that Chery’s hybrid technology Kunpeng e+ was a two-way balanced design structure, while Geely’s hybrid technology Raytheon engine was a planetary gear structure, which was exactly the difference between the two transmission paths mentioned in Geely’s statement. Moreover, Geely’s Lei Shenqing engine supports FOTA upgrade in the later stage, and more functions can be unlocked in the future.

In addition, rumors can’t stand scrutiny in time. Geely’s hybrid technology Lei Shenqing applied for a patent in 2018, while Chery applied for a patent in 2019.

At present, the domestic hybrid market is full of flowers, and each family has its own specialty skills. BYD’s DM-i, Great Wall’s lemon DHT, Geely’s Lei Shenqing Hi·X and Chery’s Kunpeng DHT have all been put on specific models and achieved mass production. Rumors and excuses are not enough to destroy technology, which is stronger, and the real market will give an answer sooner or later.

Ideal official: MEGA is expected to sell within 600,000 yuan.

  [car home Information] Recently, we learned from the ideal official that the estimated price of (|) Max is less than 600,000 yuan (presumably Max is a top model, and ideal models are generally divided into Air, Pro and Max versions), and the official price will be announced at the press conference in December 2023. The ideal MEGA reservation will be opened at 9:40 on November 17th, with a deposit of 5,000 yuan, and the reservation fee can be refunded. The first batch of test drive will be opened on January 13th, 2024, and the order will be confirmed after opening, with priority delivery on January 31st. In January, 2024, the ideal MEGA show car and test drive car will arrive at the retail center in LI, a city. MEGA delivery will start in late February.

Home of the car

  Just yesterday, we just saw the interior declaration map of the ideal MEGA in the Ministry of Industry and Information Technology, including relevant parameters. Let’s review it again. According to the application information, the length, width and height of the new car are 5350/1965/1850mm and the wheelbase is 3300mm respectively. The size of this model has exceeded the ideal L9. Compared with L9, the length of MEGA is 132mm, the width is 33mm, the height is 50mm and the wheelbase is 195mm. It can be seen that the size of this car will be very large, and such a large wheelbase will increase the space experience inside the car, but it will be a test for turning around at the intersection.

  The focus of this time is that the new car declared a picture taken from the trunk. It can be seen that the new car still adopts three rows and seven seats, and adopts the traditional MPV layout mode of 2+2+3. However, due to the long length of the car, a considerable space is reserved in the trunk. Under normal circumstances, the longitudinal length of the trunk is 680 mm.. The third row of seats is more interesting. Not only can the backrest be folded forward to expand the space, but it can also be turned forward completely to form a longer storage space. After the three rows of seats are folded and turned over, the depth of the luggage compartment reaches 1066 mm.

  Judging from the interior, although it is not very clear, there is a high probability that the center console may continue the interior design and layout of the ideal family model. At the same time, the new car adopts a split skylight design, and the second row should also provide an independent screen. The picture does not show the luxury of the second row of seats, but you can see that there are independent handrails on both sides and a wide aisle in the center.

The bathroom in the mall was occupied by "online celebrity" for a few hours, and the cleaning aunt was worried.

  In Hangzhou, it seems that you can meet Miss online celebrity, who looks good everywhere, and all kinds of online celebrity punching places. Wave after wave of street beats often attract people to stop and watch. However, this place is a little special — — The bathroom in a shopping mall.

  Some readers broke the news that the bathroom in 501 City Square of Hangzhou Tower was "occupied" by a group of online celebrity with big bags and small bags, and they changed their clothes and took pictures in it for hours.

  Yesterday at noon, our reporter came to the shopping mall, and the bathroom was really tall: the floor was neat, soft chairs and high stools, with plenty of light, the whole area was large and spacious, with glass mirrors on the whole wall and simple lines of tiles, without a trace of odor. No wonder online celebrity ladies are willing to take pictures here. Maybe it’s the weekend. It’s said that there are busy toilets on the second and third floors, and people who haven’t taken pictures appear around two o’clock in the afternoon.

  The reporter met two groups of little online celebrity who took pictures, one in a bathroom on the fourth floor that has not yet been activated; There are two girls taking pictures of each other. There are several big bags of clothes on the ground. There are clothes and shoes on the table and on the ground.

  Free, good environment and high value.

  The bathroom in the shopping mall has become a photography shed.

  As soon as she stepped into this unused bathroom, a girl who was taking pictures kindly reminded the reporter, "It’s not available here yet, and there is another bathroom next door." The reporter saw that there were two big black plastic bags in the corner of the bathroom door, and some clothes were piled on the ground, which looked like they were replaced after shooting. They shoot autumn and winter clothes, including sweaters, coats, etc., which are very fast, or stand or sit. After a few movements, a suit is finished. These two said that they are just shop assistants, so they came here to shoot because they are new in different seasons.

  The reporter found that the two bathrooms were a little messy, and the entrance and exit were not affected. This is not enabled, and the girl will remind the customers who come in from time to time that they can’t use it yet. Another normal bathroom was not greatly affected yesterday. A girl surnamed Mu told reporters that they run a physical store. "Because the environment here is good and there is no charge, I came here to take pictures." Between talking to the reporter, she cut the photos conveniently.

  "These photos are for customers and friends." Mu Girl said, "Taobao people generally don’t come here to shoot, but go to those paid shooting bases." She said that she was a wholesaler in Sijiqing clothing market, and she had taken photos outside before, but it was inconvenient to change clothes, so she chose the bathroom in the shopping mall.

  There are too many things to waste.

  Aunt cleaning should wipe the floor with a towel.

  "I often come here, and I always see people taking pictures in it, which has a little influence." Ms. Gu said.

  Many shopping guides and waiters in the shopping mall also said that they can often see these girls taking pictures. "Sometimes there are many people, sometimes there are few people, not necessarily." Aunt Wu is a cleaning staff in the shopping mall. She started to work in the shopping mall last year. "They all put on makeup, and they changed clothes and took photos as soon as they came." At most, Aunt Wu has seen three or four people taking pictures together. "Sometimes, the bathroom is all things they bring from here to there, and they can’t walk away."

  Some people have less clothes and shoot fast. "Some people leave after shooting for more than an hour; Some people have a lot of goods, three or four bags, shoes and hats, and it takes several hours to shoot. " Aunt Wu generally advises them not to occupy a stool and leave it to customers in need as much as possible. "Some people will say hello to me when they leave, saying that aunt I am leaving, so please. Some are not very polite. "

  What bothers Aunt Wu most is the "garbage" they left behind. "It was not intentionally lost, and some tags, labels and stickers fell to the ground. The label is ok. Yesterday, there were two round things stuck on the ground and I couldn’t pick them up for a long time. " There are many furry clothes in autumn and winter. Aunt Wu said that at the end of the day, "Little Mao Mao is everywhere, and some sweaters are good at shedding hair. Look at nothing. When the towel is wiped, it’s all dirty. The hair on the ground, we are not allowed to use a sponge mop, we can only wipe it with a towel, and the towels can’t be cleaned. "

  There are also complaints from customers that girls who want to take pictures should not occupy the bathroom. Aunt Wu smiled bitterly. "It’s useless for me to persuade, but I still want to come."

  Shopping mall management is very helpless.

  Many places in Hangzhou have been "occupied"

  This phenomenon is not unique to the 501 City Plaza of Hangzhou Tower. Besides occupying the bathroom, some people even make up and change clothes in the maternal and child room. Vientiane City, in77, and Leti Port, many high-value toilets or maternity rooms have the helplessness of "blaming me for the decoration". Some readers left a message, and I met it in Vientiane City before. The photographer patted it there regardless of the people around him who were eating, and he also used the flash. It was really unpleasant to sit next to him and eat.

  Mummy, a netizen, complained that she was once in the maternal and child room of Yintai in77 on the lakeside. She originally wanted to change the baby’s diaper, and waited at the door for a long time, but no one paid attention to knocking at the door. "Later, a girl in baby clothes came to knock at the door, and the door opened, and there was also a cosplay costume inside. I said that you are not a mother and baby, what are you doing in the mother and baby room? " As a result, the other party said that there was something wrong.

  Some netizens also put forward various suggestions. Aunt cleaning has been working very hard all day, so please keep these online celebrity girls as clean as possible.

  Does the mall know about this situation? How is it managed? A staff member surnamed Tong said, "As a shopping mall, we can only say that customers are welcome to come, and it is not good to label others. After all, they are also customers who come to spend, so we are not good at driving them away."

  Ms. Tong said that the shopping mall welcomes all customers to come. As for the use of the bathroom, the shopping mall is also trying its best to guide them. "There will be staff to inspect at ordinary times, and people have always taken pictures. On weekends, the passenger flow in shopping malls is relatively large, and customers will use the bathroom more frequently, which will still have an impact. "

  Some netizens suggested that monitoring should be installed in public areas such as toilets to put an end to this phenomenon. Ms. Tong said that this is more difficult to achieve. "The bathroom is a relatively private space after all, and it is impossible to install monitoring even in public areas such as the sink."

Sodium ion power battery debut, low-cost thousand-kilometer battery life is coming?

Finally, the sodium ion battery is coming!

A few days ago, China Chemical and Physical Power Industry Association announced that from October 8 to November 7, the whole network would solicit opinions on the General Specification for Sodium Ion Batteries. This general specification is mainly applicable to automotive power batteries, energy storage and other fields. If it goes well, it is expected to be released and implemented around November.

Domestic battery companies such as Contemporary Amperex Technology Co., Limited, BYD, Huayang, Chuanyi Technology and Vico Technology have already entered the sodium ion battery market, among which Contemporary Amperex Technology Co., Limited has made continuous technological breakthroughs.

However, at present, the electric vehicles on the market are basically lithium batteries, and a few high-end models are trying semi-solid batteries and solid batteries. Do we really need sodium ion batteries?

At present, there are two kinds of batteries commonly used in electric vehicles, namely lithium iron phosphate battery and ternary lithium battery. The main difference between these two batteries is that lithium iron phosphate battery has lower cost and higher safety, but its energy density is too low. Except BYD, other car companies basically only carry lithium iron phosphate batteries in low-end models.

The advantage of ternary lithium battery lies in its high energy density, while the disadvantage lies in its slightly higher risk and cost, and it is easier to deflagrate than lithium iron phosphate battery.

However, the theoretical energy density of ternary lithium battery will not exceed 500Wh/kg, and the energy density of 21700 battery introduced by Tesla can reach 300Wh/kg, which is the limit level of current power battery. According to the calculation of power consumption of 15 degrees per 100 kilometers, the battery weight of a car with a battery life of 1000 kilometers will be as high as 500kg or more.

The charging speed of electric vehicles is far less than that of fuel vehicles. Even if the number of charging piles is equal to that of fuel guns, it is more likely to cause congestion and queuing, so car owners generally have endurance anxiety. The battery life of domestic mainstream electric vehicles is usually 450 km ~650 km, which cannot solve the anxiety of car owners.

Therefore, many car companies and battery companies have been developing solid-state batteries. The lower limit of the energy density of solid-state batteries can almost be said to be the upper limit of the energy density of ternary lithium batteries. A casual search of relevant reports shows that the energy density of the solid-state battery jointly developed by Enli Power and Softbank Company is relatively low compared with other similar products, which can reach 300Wh/kg, while the energy density of the solid-state battery developed by NASA has reached an astonishing 500Wh/kg.

It seems that everything is beautiful, except the cost is slightly higher, but we may have overlooked a problem, whether it is lithium iron phosphate battery, ternary lithium battery or solid-state battery, it is inseparable from lithium.

According to the data of US Geological Survey (USGS), there are only about 98 million tons of lithium resources on the earth (data in 2022). Although half of the proven resources are in the hands of China enterprises, we must admit that this lithium mine resource is not enough to realize the electrification transformation of the global automobile industry. For this reason, Tesla will build its own lithium ore refining plant to improve the utilization rate of lithium ore resources.

The content of sodium ranks sixth, more than 400 times that of lithium. Rich in content and easy to mine, the cost of sodium ion battery is naturally much lower than that of lithium battery. For the sake of cost and environmental protection, sodium ion batteries are the best choice for low-cost and long battery life in low-end models.

In addition to low cost, sodium ion batteries have two advantages, that is, higher safety and better performance at low temperature. Even in the cold areas in the north, there is no need to worry that the winter temperature is too low and the battery life of electric vehicles will drop sharply.

Sodium ion battery seems to be the hope of realizing low cost and long battery life, but there is still a problem that sodium ion battery needs to solve, that is, the energy density is too low!

At the 15th Shenzhen International Battery Technology Exhibition in May this year, Tuobang released a sodium ion battery with an energy density of only 120Wh/kg, which is expected to increase to 160Wh/kg in 2025, even worse than lithium iron phosphate battery.

According to the data released by the second sodium ion battery industry chain and standard development forum held in July, the average energy density of the products evaluated by 17 sodium ion battery enterprises is only 104.1Wh/kg, which can be said to be terrible and not suitable for electric vehicles at all for the time being.

Contemporary Amperex Technology Co., Limited, the power battery company with the highest installed capacity in the world, invested heavily in the research and development of sodium ion batteries, and released the first generation of sodium ion batteries in 2021, with an energy density of 160Wh/kg. At the Shanghai Auto Show, companies such as Cherry and Chery announced that they would launch cars equipped with Contemporary Amperex Technology Co., Limited sodium ion batteries in the fourth quarter of this year, and the energy density of the second generation sodium ion batteries in Contemporary Amperex Technology Co., Limited could reach 200Wh/kg.

However, 200Wh/kg is obviously not enough to achieve 1000 km battery life and solve the anxiety of car owners. Similarly, according to the energy consumption of 15 degrees per 100 kilometers, the sodium ion battery pack with a battery life of 1000 kilometers weighs as high as 750kg. The weight of an ordinary B-class car is about 2000kg. If it is a medium-sized SUV, it is about 2500kg, and the proportion of batteries is too high.

Not only that, the battery also needs to occupy a lot of space. The energy density of the second generation sodium ion battery in Contemporary Amperex Technology Co., Limited is about 350Wh/L according to the volume, and the battery needs about 0.43 m space for 100 kilometers.

At present, some new energy vehicles adopt the skylight design because the bottom battery takes up too much space. If the traditional skylight design is adopted, the head space is likely to be too crowded. The dead weight of the battery will also affect the battery life. A car with too high weight needs a larger battery capacity to achieve the same battery life, occupying too much space and reducing the ride comfort.

The urgent task of sodium ion battery is still to improve the energy density, which is expected to reach 300Wh/kg, so that it is possible to achieve a long battery life of 1000 kilometers on ordinary models.

As far as the current situation is concerned, sodium ion batteries have the opportunity to gradually replace lithium iron phosphate batteries, and realize the tripartite confrontation with ternary lithium batteries and solid-state batteries in the future.

After the sodium ion battery is commercialized, the position of lithium iron phosphate battery will inevitably be very embarrassing, because the battery has the advantages of low cost and high safety, and all sodium ion batteries have it, and it performs better.

Chen Liquan, an academician of China Academy of Engineering, said that the cost of sodium ion batteries will be 20% lower than that of lithium iron phosphate batteries.

Xiaotong believes that in the future, the distribution of power batteries in the domestic automobile industry is likely to be dominated by sodium ion batteries, ternary lithium batteries and solid-state batteries.Among them, sodium ion batteries replace lithium iron phosphate batteries, which are mainly used in vehicles with less than 150,000 yuan, ternary lithium batteries are mainly used in high-end vehicles with 150,000 yuan to 350,000 yuan, and solid-state batteries are used in high-end vehicles with more than 350,000 yuan.

It should be noted that due to the influence of space and weight, sodium ion battery electric vehicles are unlikely to have a version with a battery life of 1000 kilometers, and the battery life is expected to be generally between 400 kilometers and 600 kilometers.

Ternary lithium batteries may have a small number of models with a battery life of 1000 kilometers, but the general battery life is expected to be 550 kilometers to 800 kilometers. The battery life of solid-state battery electric vehicles is likely to be more than 700 kilometers, and there are likely to be many models with a battery life of 1000 kilometers.

Of course, these predictions are all domestic cars, and the strategies of joint venture cars and domestic cars are different, so they don’t care so much about cost performance, so there may be some completely different results from domestic cars.
