Feng Xingya introduced GAC's cutting-edge technology in the field of automotive technology
An important breakthrough has been made in the all-solid-state power battery, which will be installed in 2026
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 a technological highland for the electrification transformation of the global automotive industry. At present, GAC Group has initially opened up the whole process manufacturing process of all-solid-state batteries, and has made a key technological breakthrough in the mass production of automotive-grade high-safety and large-capacity all-solid-state power batteries, with three core advantages of ultra-high energy density, ultra-high safety and large-capacity all-solid-state batteries, which are expected to be installed in Haobo models in 2026.
Li Jin, head of GAC Aion's battery R&D department, explained GAC's all-solid-state power battery technology
GAC's all-solid-state power battery adopts high-areal 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 areal capacity of more than 5mAh/cm2, thereby achieving an energy density of more than 400Wh/kg. Compared with the most advanced liquid lithium-ion battery, its volume energy density and mass energy density are increased by more than 50%, so that the vehicle mileage can exceed 1000km.

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 all-solid-state power battery has successfully established the full-process manufacturing process of all-solid-state power battery by trying more than 100 kinds of material solutions and process solutions, and 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), laying the foundation for the application of automotive-grade all-solid-state power batteries.
The R&D and application of all-solid-state power battery technology will greatly enhance the performance and market competitiveness of GAC Group's products, help promote GAC Group's scientific and technological innovation and high-quality and sustainable development, and will also have a positive impact on the development of the entire new energy vehicle industry.
The leading domestic and full-scene pure visual intelligent driving system without pictures
The main battlefield of the new round of scientific and technological competition in the automotive industry is intelligent networked new energy vehicles, and intelligence, especially automatic driving, has become the focus of competition. GAC Group, with its strong scientific and technological strength, has a leading edge in the field of intelligent driving, and has many advanced intelligent driving technologies, including super parking that can complete extreme space parking, one-key summoning and driving, and cross-layer driving with large curvature slopes, as well as high-speed NDA, urban NDA, traffic congestion pilot TJP, etc., and has realized the demonstration operation of Robotaxi in the field of unmanned driving.
Compared with the current mainstream technology route, it not only does not need high-precision maps, but also does not rely on lidar, but combines visual sensors and industry-leading AI algorithms to perceive the world like a human, and can achieve intelligent driving with a wider coverage with a more concise hardware system, bringing users a richer, freer, and full-scene driving experience.

GAC's picture-free pure visual intelligent driving system has three leading capabilities in visual recognition, making it a significant advantage in the field of autonomous driving. First, the ability to understand complex traffic roads with extreme accuracy. Whether it's a ramp, tunnel, curve, intersection, fork in the road, and other complex scenarios, the system can accurately identify and understand the structure of the road. Secondly, super traffic light recognition ability. The system uses a deep neural network to accurately identify various signal elements, including the type of signal light, various symbols and colors, countdown to countdown, and flashing status. Thirdly, the ability to handle complex and changeable scenarios. The sensing range of this system reaches 150+ meters in front of the car, 100 meters behind the car, and 50 meters around the car, which is 1.5 times the industry level.
In terms of decision-making and action, GAC's pictureless pure visual intelligent driving system also performs well. Through real-time tracking, intent recognition and trajectory prediction of dynamic traffic objects, as well as a command brain that is data-driven and coordinated with expert rules, the system can accurately predict the behavior of other traffic participants and make reasonable, safe and efficient driving decisions with the help of GAC's first fluid-based space-time joint planning technology. In addition, in the parking scene, this system also shows excellent performance, the minimum error can be controlled to 5cm, which can achieve the industry's most difficult three-dimensional parking space, narrow parking space parking function.
In addition, GAC's pictureless pure visual intelligent driving system has the ability to continuously learn and evolve. With the help of the self-developed data closed-loop and simulation system, this system can continuously iterate and optimize the algorithm in the simulation test 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: the mainstream "multi-sensor fusion technology" and the forward-looking "pure vision technology without pictures", and both routes will get rid of the dependence on high-precision maps. At present, the coverage rate of high-precision maps only accounts for about 6% of the national highway mileage, which means that automatic driving based on high-precision maps is unusable in about 94% of highway sections in the country, while GAC's two technical routes are "open with navigation".
GAC Group launched an autonomous driving data solution through Ruqi Mobility
As an important foundation for the continuous iteration of autonomous driving, GAC Group is actively building a closed loop of data from multiple dimensions, and has invested in the construction of GAC Cloud Data Center, GAC Intelligent Connected Big Data Platform, etc., and has launched a data annotation platform ONTIME Data Encoder, a high-precision map tool chain ONTIME MapNet, and an intelligent driving simulation platform ONTIME through Ruqi Travel NexSim's autonomous driving data solutions in three major segments take data as the core to drive closed-loop iteration of autonomous driving, helping GAC build an industry-leading autonomous driving engine.
