GAC Launches Solid-State Battery & Advanced Driving Tech

On April 12th, the GAC TECH DAY 2024 event with the theme of “Technology Vision” was held at the GAC GROUP Research Institute. This technology day focuses on cutting-edge technologies in smart electric vehicles, launching the domestically leading imageless pure visual 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 installed on vehicles in 2026. The event also showcased advanced technologies such as electromagnetic suspension and flying cars from GAC Group, fully demonstrating GAC Group’s independent research and development capabilities.

Significant breakthroughs have been made in all solid-state batteries, achieving installation and installation in vehicles by 2026

As a core component of new energy vehicles, power batteries are directly related to key indicators such as range and safety. 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 preliminarily integrated the entire manufacturing process of all solid state batteries and achieved key technological breakthroughs in the mass production of vehicle grade high safety and large capacity all solid state power batteries. It has three core advantages: ultra-high energy density, ultra-high safety, and large capacity all solid state battery cells. It is expected to be installed on vehicles in 2026.

The GAC GROUP all solid state power battery adopts high surface capacity solid-state positive electrode technology and third-generation sponge silicon negative electrode technology (new nano silicon composite negative electrode). The all solid state positive electrode can achieve a high surface capacity of over 5mAh/cm2, and thus achieve an energy density of over 400Wh/kg. Compared to the most advanced liquid lithium-ion batteries currently available, their volumetric energy density and mass energy density have increased by more than 50%, allowing the vehicle’s range to exceed 1000km.

In terms of safety, the GAC GROUP all solid state power battery adopts a high-strength and dense composite electrolyte film, which ensures that the battery does not explode during 200 ° C hot box testing, breaking a new height in the safety of high specific energy batteries. In addition, the battery has maintained stable performance under extreme conditions such as needle piercing, cutting, -78 ° C dry ice environment, and 90 ° C high-temperature hot water immersion. It does not experience thermal runaway under mechanical abuse conditions such as nail piercing and cutting, significantly improving the safety of the vehicle.

In terms of battery cell capacity, GAC GROUP has successfully established a full process manufacturing process for all solid state power batteries by attempting over a hundred material and process schemes, achieving the manufacturing of large-sized multi-layer stacked all solid state battery cells with a capacity of up to 30Ah, far exceeding the current industry’s highest level (10Ah-15Ah), laying the foundation for the application of automotive grade all solid state power batteries.

The research and application of all solid state power battery technology will greatly enhance the performance and market competitiveness of GAC GROUP’s products, help promote technological innovation and high-quality, sustainable development of GAC Group, and also have a positive impact on the development of the entire new energy vehicle industry.

Leading all scene visual intelligent driving system without graphics

The main battlefield of the new round of technology competition in the automotive industry is intelligent connected new energy vehicles, and intelligence, especially autonomous driving, has become the focus of competition. GAC GROUP, with strong technological strength, has a leading advantage in the field of intelligent driving, with numerous advanced intelligent driving technologies, including super parking that can complete extreme space parking, one click call and pick up, cross layer driving with large curvature and slope, as well as high-speed NDA, urban NDA, traffic congestion leading TJP, etc. Robotaxi has achieved demonstration operation in the field of autonomous driving.

The imageless pure visual intelligent driving system launched on this technology day can be applied to complex and ever-changing scenarios. Compared with the current mainstream technology route, it not only does not require high-precision maps, nor does it rely on LiDAR, but also combines visual sensors and industry-leading AI algorithms to perceive the world like humans. With a simpler hardware system, it can achieve a wider range of intelligent driving, bringing users a richer, more free, and full scene driving experience.

The imageless pure visual intelligent driving system has three leading capabilities in visual recognition, giving it a significant advantage in the field of autonomous driving. Firstly, the ability to understand complex traffic roads with extreme precision. This system can accurately identify and understand the structure of roads in complex scenarios such as ramps, tunnels, bends, intersections, and forks. Secondly, it has strong traffic signal recognition ability. This system achieves accurate recognition of various signal light elements through deep neural networks, including signal light types, various symbols and colors, countdown counting, and flashing status. Once again, the ability to handle complex and ever-changing scenarios. This system has a perception range of 150+meters in front of the car, 100 meters behind the car, and about 50 meters, which is 1.5 times the industry level. In addition to common traffic factors such as vehicles, pedestrians, riders, and small animals, the perception categories also include irregular obstacles such as small carts and camp tents.

In terms of decision-making and action, the imageless pure visual intelligent driving system also performs well. By real-time tracking, intent recognition, and trajectory prediction of dynamic traffic objects, as well as a data-driven and expert rule-based command brain, and leveraging GAC GROUP’s pioneering fluid based spatiotemporal joint planning technology, this system can accurately predict the behavior of other traffic participants and make reasonable, safe, and efficient driving decisions. In addition, in parking scenarios, this system also demonstrates excellent performance, with a minimum error controlled to 5cm, enabling the industry’s most challenging three-dimensional and narrow parking functions.

In addition, the imageless pure visual intelligent driving system has the ability to continuously learn and evolve. With the help of self-developed data closed-loop and simulation system, this system can continuously iterate and optimize algorithms in simulation testing, achieving self improvement and evolution.

It is worth noting that GAC GROUP has laid out both mainstream “multi-sensor fusion technology” and forward-looking “imageless pure visual technology” in the field of autonomous driving technology, and both GAC GROUP routes will break away from dependence on high-precision maps. At present, the coverage of high-precision maps only accounts for about 6% of the country’s road mileage, which means that autonomous driving based on high-precision maps cannot be used in about 94% of the country’s road sections, while both GAC GROUP technology routes achieve “navigation enabled driving”.

As an important foundation for the continuous iteration of autonomous driving, GAC GROUP is actively building a data loop from multiple dimensions. It has invested in the construction of GAC Cloud Data Center, GAC Intelligent Network Connected Big Data Platform, etc., with data as the core, driving the iteration of autonomous driving loop, and helping GAC GROUP build an industry-leading autonomous driving engine.
