On the 2024 GAC Science and Technology Day, GAC Group once again "showed its muscles" in a high-profile manner.
MLounge Qiji first-class cabin, flying car, MBoard 2.0 Qiji Xinzhi chassis, electromagnetic suspension, etc., are all the focus of attention in the industry without exception. However, the highlight of this science and technology day is the GAC all-solid-state battery and the pictureless pure visual intelligent driving that will be officially launched in 2026.
In particular, all-solid-state batteries, due to high technical barriers and difficult research and development, opponents who are catching up with the schedule basically put the time point of mass production after 2028. The GAC Group dared to advance to 2026 and launch all-solid-state batteries and pure visual intelligent driving without pictures at the same time, which shows that there are really "two brushes".
Accelerate the mass production of all-solid-state batteries, and GAC will impact the technological highland
Solid-state batteries are actually one of the hottest topics in the automotive industry recently, and they have shown great potential in terms of energy density and safety. However, due to the difficulty of solid-state battery research and development, including multinational giants such as BMW, Volkswagen, and Toyota, no car company has officially mass-produced cars. Recently, Zhiji Automobile has been pushed into the field of public opinion due to semi-solid-state batteries, which shows that there is a high degree of attention to the large-scale commercial use of all-solid-state batteries inside and outside the industry.
According to GAC Group, the whole process manufacturing process of all-solid-state batteries has been preliminarily opened, and a key technological breakthrough has been made in the mass production of automotive-grade high-safety and large-capacity all-solid-state power batteries, with three core advantages: ultra-high energy density, ultra-high safety and large-capacity all-solid-state batteries.
Among them, GAC's all-solid-state power battery adopts high-capacity solid-state cathode technology and third-generation sponge silicon anode technology (new nano-silicon composite anode), and the all-solid-state cathode can achieve a high surface capacity of more than 5mAh/cm2, thereby achieving an energy density of more than 400Wh/kg.
In terms of safety, GAC's all-solid-state power battery adopts a high-strength and dense composite electrolyte film, so that the battery will not explode in the 200°C hot box test, refreshing a new height of high specific energy battery safety. In addition, the battery maintains stable performance under extreme conditions such as acupuncture, cutting, minus 78 °C dry ice environment, and 90 °C high-temperature hot water immersion, and does not cause thermal runaway under mechanical abuse conditions such as nailing and cutting, which significantly improves the safety of the car.
In terms of cell capacity, GAC's all-solid-state power battery has realized the manufacture of large-size multi-layer stacked all-solid-state batteries, with a capacity of up to 30Ah, far exceeding the current industry highest level (10Ah-15Ah).
However, Toyota has also announced that it will launch pure electric vehicles equipped with all-solid-state batteries in 2027-2028, and its solid-state batteries can achieve a range of 1,200 kilometers in 10 minutes. In addition, BMW and Volkswagen also plan to mass-produce all-solid-state batteries in the past two years, and GAC Group will also face more fierce competition for all-solid-state batteries.
It is foreseeable that the all-solid-state power battery, which will be installed in Haobo models in 2026 with a range of more than 1,000 kilometers, will undoubtedly have a significant effect on improving the competitiveness of GAC Group's models. It makes GAC Group stand on the technological highland of electrification transformation.
智能驾驶，广汽已经是Next level
As we all know, most car companies are relying on lidar and high-precision maps to promote intelligent driving, and only a few dare to adopt pure vision solutions. For example, Tesla's models, as well as the Zhijie S7 that has just been relaunched, use the basic version of Huawei's visual intelligent driving HUAWEI ADS.
According to Brother Yuluo, the pure vision solution can reduce the cost of car manufacturing and better popularize intelligent driving. However, the pure visual solution without pictures has higher technical difficulties. Intelligent driving is a must in the era of electrification, and the pictureless pure visual intelligent driving system released by GAC Group on Science and Technology Day, combined with visual sensors and industry-leading AI algorithms, perceives the world like a human, and can achieve intelligent driving with a wider coverage with a more concise hardware system, which can be said to be the next level.
GAC's pictureless pure visual intelligent driving system has three leading capabilities in visual recognition, one is the ability to understand complex traffic roads with extreme accuracy. The second is the super traffic light recognition ability. Third, in terms of decision-making and action, through the real-time tracking, intention recognition and trajectory prediction of dynamic traffic objects, as well as the command brain that is data-driven and coordinated with expert rules, it can accurately predict the behavior of other traffic participants and make reasonable, safe and efficient driving decisions.
Other leading advantages include that in the parking scene, the minimum error can be controlled to 5cm, which can realize the industry's most difficult three-dimensional parking space and narrow parking space parking function. As well as the ability to continuously learn and evolve, and continuously iterate and optimize algorithms in simulation tests to achieve self-improvement and evolution.
It is worth noting that GAC has laid out two major technical routes in the field of autonomous driving technology: mainstream "multi-sensor fusion technology" and forward-looking "pure vision technology without pictures", and both GAC routes will get rid of the dependence on high-precision maps and achieve "navigation can be opened".
Write at the end
In this era of enthusiasm for traffic and price wars, the importance of technology to car companies is often ignored, and the phenomenon of putting the cart before the horse emerges in endlessly. However, car companies that believe in long-termism will always regard technology as the foundation of brand development. Just like GAC Group, it will invest nearly 8.4 billion yuan in independent research and development in 2023, and it has continued to invest for many years to achieve strong R&D strength and innovation capabilities. If there is a material, it will be shown, and the all-solid-state battery and pictureless pure visual intelligent driving released by GAC Science and Technology Day are enough to lead the future of smart electricity!
