Guangzhou Automobile Science and Technology Day was released, and all-solid-state batteries and pure visual intelligent driving led a new era.
On April 12th, GAC TECH DAY 2024 with the theme of "Science and Technology Vision" was held in Guangzhou Automobile Research Institute. This Science and Technology Day focuses on the cutting-edge technology of smart electricity, and introduces the domestic leading unmanned pure vision intelligent driving system and the high-safety and large-capacity all-solid-state power battery that achieves key technological breakthroughs. Both technologies are planned to be loaded in 2026.
An important breakthrough has been made in all-solid-state power batteries.
As the core component of new energy vehicles, power batteries are directly related to key indicators such as cruising range and safety, and the development of power battery technology is also the technological highland for the electrification transformation of the global automobile industry. At present, the whole-process manufacturing process of all-solid-state battery has been initially opened, and the key technical breakthrough of mass production of all-solid-state power battery with high safety and large capacity has been achieved. It has three core advantages of ultra-high energy density, ultra-high safety and large-capacity all-solid-state battery, and it is expected to be loaded on vehicles in 2026.
Guangzhou automobile all-solid-state power battery adopts high surface capacity solid-state anode technology and the third generation sponge silicon anode technology (new nano-silicon composite anode), and the all-solid-state anode can reach 5mAh/cm.2Above the high surface capacity, and then realize the energy density of more than 400Wh/kg. Compared with the most advanced liquid lithium-ion battery at present, 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.
Full-scene map-free pure visual intelligent driving system
This Science and Technology Day also launched the Guangzhou Automobile Map-free pure visual intelligent driving system, which can be applied to complex and changeable full scenes. Compared with the current mainstream technical routes, it not only does not need high-precision maps, but also does not rely on lidar. Instead, it combines visual sensors and the industry’s top AI algorithm to perceive the world like a human being, and can realize intelligent driving with a wider coverage with a simpler hardware system, bringing users a richer, more free and full-scene driving experience.
Guangzhou Automobile No-Map Pure Visual Intelligent Driving System has three leading abilities in visual recognition, which makes it have significant advantages in the field of automatic driving. First of all, the ability to understand complex traffic roads with great accuracy. Whether it is ramp, tunnel, bend or intersection, fork road and other complex scenes, this system can accurately identify and understand the road structure. Secondly, super traffic light recognition ability.
In terms of decision-making and action, GAC’s map-free pure visual intelligent driving system also performed well. Through the real-time tracking of dynamic traffic objects, intention identification and trajectory prediction, and the command brain driven by data and expert rules, this system can accurately predict the behavior of other traffic participants and make reasonable, safe and efficient driving decisions with the help of the fluid joint planning technology pioneered by GAC.
In addition, GAC’s map-free pure visual intelligent driving system has the ability of continuous learning and evolution. With the help of self-developed data closed-loop and simulation system, this system can iteratively optimize the algorithm in the simulation test and realize self-improvement and evolution.
Promoting high-quality development with scientific and technological innovation
On this Science and Technology Day, Guangzhou Automobile Group also exhibited 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 developed in depth for users with mobility difficulties.
Previously, Guangzhou Automobile Group’s first flying car, GOVE, made its first flight in the world on Guangzhou Science and Technology Day in 2023, and demonstrated its flight over Guangzhou CBD in March this year, completing the flight verification in the complex low-altitude environment of urban public for the first time, which has taken an important step for the exploration of air traffic demonstration operation in Guangzhou City.
Guangzhou Automobile’s new light business sector, Qiji Automobile, was officially released on this Science and Technology Day. The live demonstration of MLounge Qiji First Class supports L2-L4 intelligent driving and will be mass-produced this year.
Chuanqi new energy E9 well-being vehicle displayed on the spot is a profound embodiment of social responsibility and humanistic care of GAC.
Car power said:
Facing the future, Guangzhou Automobile Group will rely on its strong R&D strength and rich patent achievements to deepen the fields of intelligent driving and new energy vehicles, accelerate the cultivation and expansion of new quality productivity, draw the grand blueprint of "Trillion Guangzhou Automobile", and actively contribute to the high-quality development of Guangzhou and even the whole country’s automobile industry and build a strong automobile country.
