"All-solid-state battery"+"Picture-free pure visual intelligent driving", is GAC leading again?

China Economic News Network (Xing Rui)On April 12th, Guangzhou Automobile Group held 2024 Guangzhou Automobile Science and Technology Day to show the public the latest achievements in the field of scientific and technological innovation. Among them, two achievements are the most striking: one is the automatic driving technology without high-precision maps, which is more human-like, and the other is the more efficient and safer all-solid-state battery technology.

"In the past Science and Technology Day, we released a series of leading technologies, such as ADiGO Intelligent Driving Interconnected Ecosystem, GPMA Vehicle Architecture, GEP Pure Electric Platform, Super Fast Rechargeable Battery, Hydrogen Fuel Cell Vehicle and Hydrogen Hybrid Vehicle, and even Flying Vehicle, most of which have been applied in mass production." Feng Xingya, General Manager of Guangzhou Automobile GroupTaking the lead in introducing the topic with "magazine battery", he said that the high-safety "magazine battery" has served about 800,000 users and achieved zero spontaneous combustion of nearly 48 billion kilometers. He turned his head. "Today, the ultra-high safety and large-capacity all-solid-state battery technology we brought has gone further. Compared with the most advanced liquid lithium-ion batteries and semi-solid-state batteries, it has achieved a revolutionary improvement in battery safety."

In terms of the technical breakthrough of "all-solid-state battery", Li Jin, head of the research and development department of Guangzhou Automobile Ai ‘an battery, gave a detailed introduction. Guangzhou Automobile Group has initially opened up the whole process manufacturing process of all-solid-state battery, and achieved the key technical breakthrough in mass production of all-solid-state power battery with high safety and large capacity.

The first is ultra-high energy density. Guangzhou automobile all-solid-state power battery adopts high surface capacity solid-state anode technology and the third generation sponge silicon anode technology, and the all-solid-state anode can reach 5mAh/cm?Above the high surface capacity, and then realize the energy density of more than 400Wh/kg. Compared with the current advanced liquid lithium-ion battery, its volume energy density and mass energy density are increased by more than 50%, and the cruising range of the whole vehicle can exceed 1000km.

Followed by ultra-high security. Guangzhou Automobile All-solid-state Power Battery adopts high-strength and compact composite electrolyte membrane, which makes the battery not explode in the hot box test at 200°C, and refreshes the new safety height of high specific energy battery. In addition, the battery keeps stable performance under extreme conditions such as needling, cutting, dry ice environment at minus 78°C, high temperature hot water immersion at 90°C, and thermal runaway does not occur under mechanical abuse conditions such as nailing and cutting, which significantly improves the safety of automobiles.

Once again, it is a large battery capacity. Guangzhou Automobile All-solid-state Power Battery has successfully established the whole process manufacturing technology of all-solid-state power battery by trying more than 100 kinds of material schemes and process schemes, and realized the manufacturing of large-size multi-layer stacked all-solid-state batteries, with a capacity as high as 30Ah, far exceeding the highest level in the current industry (10Ah-15Ah), laying a foundation for the application of all-solid-state power batteries of vehicle specifications.

"The main battlefield of the new round of science and technology competition in the automobile industry is intelligent networked new energy vehicles, and intelligence, especially autonomous driving, has become the focus of competition." Feng Xingya said that in the field of autonomous driving technology, GAC has also laid out two major technical routes: mainstream "multi-sensor fusion technology" and forward-looking "map-free pure vision technology".

At present, the coverage rate of high-precision maps only accounts for about 6% of the national highway mileage, which means that autonomous driving based on high-precision maps cannot be used in about 94% of the national highway sections. Feng Xingya said, "Both routes of Guangzhou Automobile will get rid of the dependence on high-precision maps, and our goal is ‘ Where there is a road, there is a GAC smart car ’ 。”

Another focus of this science and technology day is "no map, pure vision and intelligent driving". According to Chen Xuewen, chief scientist of artificial intelligence in Guangzhou Automobile Research Institute, the intelligent driving system has three leading abilities in visual recognition: first, the ability to understand complex traffic roads extremely accurately; Second, the super traffic signal recognition ability; The third is the ability to deal with complex and changeable scenes.He said that GAC’s map-free pure visual intelligent driving system has completely got rid of the shackles of high-precision maps, and no longer relies on lidar. With a simpler hardware system, complex and changeable full-scene automatic driving can be realized.

So far,Guangzhou Automobile Group in the field of intelligent drivingIt has many advanced intelligent driving technologies, including super parking that can complete parking in extreme space, one-button calling and driving, and cross-floor driving with large curvature gradient, as well as high-speed NDA, urban NDA, traffic jam pilot TJP, etc. In the unmanned field, it has realized the demonstration operation of Robotaxi.In addition, Guangzhou Automobile Group also demonstrated a number of advanced technologies and humanized products, including electromagnetic suspension, MBoard2.0 core intelligent chassis and flying cars, as well as Chuanqi new energy E9 well-being vehicle deeply customized and developed for users with mobility difficulties.

Guangzhou Automobile Group also released the innovation achievements in 2023. In 2023, GAC invested nearly 8.4 billion yuan in independent research and development, and nearly 3,200 new patent applications were filed, of which invention patents accounted for about 50%. Up to now, the cumulative investment in independent research and development has exceeded 45 billion yuan over the years, and about 18,600 patents have been applied, of which invention patents account for 41%.

The national six b emission standards will be fully implemented, and what changes will the automobile industry welcome?

  Xinhua News Agency, Beijing, May 23rd Question: the national six b emission standards will be fully implemented, and what changes will the automobile industry welcome?

  Xinhua News Agency reporters Zhang Xinxin, Yan Fujing, Gao Kang

  The Ministry of Ecology and Environment, the Ministry of Industry and Information Technology and other departments recently jointly issued an announcement. From July 1, 2023, the national sixth emission standard 6b stage will be fully implemented, and it is forbidden to produce, import and sell cars that do not meet the national sixth emission standard 6b stage.

  The "boots" of the emission standard policy have been put on the ground, accelerating the automobile industry to enter a new stage of green development. What changes will the full implementation of National Six B bring to the automobile market? Will the fuel vehicle market usher in a "price reduction tide"? Will it accelerate the promotion of new energy vehicles?

  The car market share of "National Sixth B" exceeds 90%, and the industry has entered a new stage.

  "National Six Standards" is a standard for preventing and controlling motor vehicle pollution emissions and improving ambient air quality. The "National Six Standards" for light vehicles set two emission limit schemes, National Six A and National Six B, which were implemented in 2020 and 2023 respectively.

  National Sixth B is about to be fully implemented, but the preparation of the market and industry is not limited to the present.

  "Since ‘ National Six Standard ’ Since its release, most enterprises have directly carried out product research and development and production in accordance with the requirements of the National Six B standard. The industry is equivalent to implementing the National Six B standard in advance, and the National Six B vehicles occupy a major market share. " The relevant person in charge of China Automobile Industry Association said that many models have already completed the transformation of National Six B, and there is no technical difficulty from the perspective of enterprise production. It is understood that since the implementation of the standard, the proportion of light-duty vehicles in the national six B vehicles has exceeded 95%, and the market share of the national six B vehicles has exceeded 90%.

  Guangzhou Automobile Group said that all its fuel vehicles have been switched to the National Six B standard; Changan Automobile also shows that there is no pressure for the arrival of National Sixth B, and the newly launched Yida is in line with the National Sixth B standard … … Facing the implementation of standards, manufacturers are ready.

  The reporter interviewed a number of industry experts and said that from the perspective of the new car market, the implementation of the National Sixth B will not have much impact on the auto market. The National Sixth B Standard has been promoted in advance in first-tier cities such as Beijing and Shanghai, and the implementation of the new regulations has little impact on the automobile market in these cities. In other cities that haven’t implemented the national six-B standard, if there are relatively many vehicles in stock in the national six-A, there will be a certain price drop in the short term, but this will be experienced in all previous emission standard switches. The development trend of green and low carbon in automobile industry itself is the embodiment of market demand, which will also accelerate the transformation of automobile enterprises and industries.

  Half-year sales transition period, to promote the smooth continuation of the market.

  The release of the national six emission standards has given the market a long adjustment window. Implementing standards in advance in key areas is conducive to alleviating the industry pressure when the policy is formally implemented.

  At the same time, the announcement made it clear that for some light-duty vehicle models such as National Six B, which were reported as "monitoring only" in the actual driving pollutant emission test (RDE test), a half-year sales transition period was given and sales were allowed until December 31, 2023. This move is also to enable manufacturers and distributors to rationally plan the layout and complete the product switching and sales as soon as possible.

  The reporter learned from China Automobile Industry Association that China Automobile Association has established an inventory scheduling mechanism with the top ten automobile groups and other member units to organize and schedule industry inventory data on a monthly basis. By the end of January 2023, there were more than 1.89 million vehicles in stock that did not meet RDE requirements.

  The person in charge of China Automobile Industry Association believes that the current inventory pressure is caused by objective factors. Among them, there are some factors such as "demand contraction, supply shock, expected weakening" and other factors such as the poor performance of the automobile market, and it takes some time for product production to switch, and new energy vehicles accelerate the replacement of traditional fuel vehicles. After months of promotion, the inventory has fallen sharply.

  "The policy gives a half-year sales transition period, which is conducive to stabilizing the mentality of dealers and enterprises, orderly destocking, and helping the car market to make a smooth transition." Cui Dongshu, secretary general of the National Passenger Car Market Information Association, said.

  Accelerate the guidance of green intelligence and promote industrial iterative upgrading.

  The industry believes that the full implementation of the national six B emission standards has a positive role in promoting the iterative upgrading of the fuel vehicle market and the new energy vehicle market.

  Recently, the the State Council executive meeting deployed to speed up the construction of charging infrastructure. The National Development and Reform Commission and the National Energy Administration issued the "Implementation Opinions on Accelerating the Construction of Charging Infrastructure to Better Support the Rural and Rural Revitalization of New Energy Vehicles". A series of policies to encourage automobile consumption, especially to support the consumption of new energy vehicles, have been introduced to accelerate the upgrading of the industry to green and intelligent.

  With industrial orientation and policy support, car companies have accelerated their layout, and the market is constantly exploring model innovation: Chery recently announced preferential measures for going to the countryside, and its "QQ Ice Cream" went to the countryside to launch 1000 yuan/Taiwan car purchase subsidies; Charging service providers can promote the penetration of business in rural areas, forming a charging service network covering 55,000 stations and 575,000 charging guns nationwide; Hangzhou Longyuan Electric Power Co., Ltd. and related units jointly worked out the optimal power supply scheme of charging station, and monitored the working state of charging pile and charging protection system in real time through digital technology & HELIP; …

  The proportion of freight new energy vehicles is constantly increasing, and the market promotion of new energy vehicles is accelerated. Take Lala as an example. In October last year, the proportion of new energy truck drivers on the platform reached 25%. According to the prospectus of Cargo Lala, by the end of last year, Cargo Lala had over 35,000 electric vehicle charging stations in over 270 cities in China.

  "Industrial upgrading is the general trend." Xu Haidong, deputy chief engineer of China Automobile Industry Association, believes that both the implementation of emission standards and the promotion of consumption policies will further promote the green transformation of the entire automobile industry and accelerate the popularization and application of new energy vehicles. The next step is to do a good job in policy implementation and continuously improve the overall competitiveness and development quality of the automobile industry.
