Success is actually quite simple, just need to be in the right place at the right time. All this seems to confirm the rapid development of the new energy automobile industry in China.
Looking back at 2021, the production and sales of a series of leading new energy vehicle companies such as Tesla, Wei Xiaoli, and BYD have refreshed the historical record. And Nezha Automobile, zero running and other second-tier and below brands are also catching up, everything is as happy as a happy state, the vitality is exuberant.
At the same time, in terms of consumer endurance, the current mainstream pure electric vehicles have easily broken through 600 kilometers, which is about the same as ordinary fuel vehicles. The difference is that problems such as energy replenishment methods and charging efficiency have still not been properly solved.
However, all this has been effectively alleviated with the emergence of GAC Aion LX Plus, and the CLTC mileage of its 1000-mile version has reached 1008 kilometers.
This means that pure electric vehicles have low pollution and high environmental protection attributes, while also having the long endurance of hybrid models.
So, how does the AION LX Plus do it?
We all know that the key to battery life is in the battery, and the key to the battery is in the energy density. However, blindly increasing the energy density has not effectively improved the endurance. In contrast, the AION LX Plus uses a silicon-containing lithium-ion battery. Compared to graphite, silicon can store more than 9 times more lithium ions. That is to say, if silicon is used as the negative electrode, the energy density of lithium batteries can be greatly improved. However, the use of silicon poles also has drawbacks, that is, after repeated charging and discharging, the material structure will become loose, and the SEI solid electrolyte film will become thicker, resulting in a decrease in battery capacity.
At this time, some people have to ask, gagac AION LX Plus is through what means to suppress the capacity decay problem?
Through unremitting efforts, the staff of GAC Research Institute has developed a complete set of "black technology" such as nano-composite silicon technology, adhesive technology with self-repair function and gradient composite coating technology to improve the service life of silicon-containing anode lithium batteries.
Among them, the nano-composite silicon technology is to control the silicon material at the nano level, control its microscopic morphology, and minimize the volume expansion during the charge and discharge of the silicon-based composite anode material. At the same time, the use of this surface-coated protective layer avoids direct contact between the silicon material and the electrolyte, and greatly improves the stability of the SEI solid electrolyte membrane. The adhesive technology with its own repair function can repair the damaged silicon anode pole plate during expansion and contraction, while the gradient composite coating technology plays a role in improving the structural stability of the negative pole plate body.
With the blessing of "black technology", the energy density of the sponge silicon anode piece lithium-ion battery equipped with AION LX Plus has reached 205Wh/kg and the capacity has reached 144.4kWh. Compared with lithium batteries of the same specification, the cell capacity of this new type of battery is increased by 25%, the cell volume is reduced by 20%, and the weight is reduced by 14%. This further improves the vehicle's performance in acceleration, braking, handling and space.
In addition to the superior endurance, the second generation of intelligent zoom lidar equipped with the new car is also worthy of attention.
The second-generation lidar on the AION LX Plus comes from Sagitar's RoboSense, which is located on the roof and the top of the front wheels on both sides of the body, which can realize cross coverage detection with a 300° field of view in front of the car, with a maximum detection distance of 250 meters. And support 10-30Hz refresh rate variable function, when driving in the city, the lidar supports 10-30Hz refresh rate variable function, can more accurately identify vehicle congestion, ghost probe and other unexpected situations. In addition, the vertical resolution of 0.2-0.05° can be dynamically adjusted, which can accurately identify small obstacles at long distances and further improve driving safety.
In addition, the car also brings users the unique high-speed NDA navigation driver assistance system, urban NDA intelligent pilot assistance and over-the-horizon summoning parking functions. With 35 high-performance perception hardware and a high-computing intelligent driving computing platform, AION LX Plus can achieve high-speed, urban area coverage and improve the level of driving intelligence. Coupled with the support for OTA over-the-air upgrade function, the in-vehicle function will be continuously upgraded and improved, bringing unprecedented experience optimization to users.
It is worth mentioning that AION LX Plus is also equipped with the latest ADiGO 4.0 intelligent IoT system, which adds voice control driving mode, energy recovery, vehicle control, etc. in the previous speech recognition control function, and the 8-core Qualcomm 8155 processor ensures the system operation responsiveness and fluency of use, greatly improving the human-computer interaction experience.
Supplemented by cross-generation intelligent technology configurations such as IBCM sensorless start after the upgrade, new AR real-life navigation, DMS+OMS cabin monitoring, etc., it enriches the diversified needs of users for intelligent vehicles.
Write at the end:
It can be said that the listing of AION LX Plus is not just a simple mileage exceeding thousands of kilometers. The use of lithium batteries with silicon anode, variable focus lidar, advanced driver assistance, and ADiGO 4.0 intelligent IoT system reflects the innovation and advanced nature of this new car.
As a product of GAC Aeg, AION LX Plus will reshape the new standard of pure electricity value in the era of new energy popularization, build a high-end technology moat for the brand, and open the "Eian era" in which China's high-end pure electricity leads the world.
