This means that the motor power is only 70 kilowatts.
GAC Aian (formerly known as GAC New Energy) is an automobile brand owned by Guangzhou Automobile Group Co., Ltd. On July 28, 2017, the GAC New Energy brand announced its official registration. It has started the construction of a factory with an initial investment of 4.697 billion and a production capacity of 200,000 vehicles per year. In the future, it will cooperate with partners to invest a total of more than 45 billion yuan to build GAC Zhilian New Energy. Automobile industrial park.
Magazine battery system safety technology
The magazine battery is developed by GAC Research Institute, GAC Research Institute Silicon Valley R&D Center, and the world’s top battery cell experts. It is composed of more than 600 top international experts. The R&D team has worked hard to build it, including more than 60 PhDs, which reflects the highest technical level of GAC Aian battery safety.
GAC conducts research and development in aspects such as power battery overcurrent protection, battery thermal suppression methods, battery thermal runaway monitoring and early warning, etc., and has formed an internationally leading patent group, including more than 80 patents, accounting for more than 70. It provides GAC Aian’s solutions for the healthy and sustainable development of the new energy automobile industry. ?
The four core technologies of the magazine battery
Super thermal insulation battery safety cabin: Through the mesh nanopore insulation material and the high-temperature-resistant upper casing, the magazine battery constructs The super thermally insulated safety cabin ultimately prevents the thermal runaway of ternary lithium batteries from spreading to adjacent batteries. At the same time, the upper shell of the battery pack can withstand temperatures above 1,400°C, thus effectively protecting the entire battery pack.
Extremely fast cooling three-dimensional rapid cooling system: Through the design of a fully integrated liquid cooling system, high-speed heat dissipation channel, and high-precision heat conduction path, the magazine battery has increased the heat dissipation area by 40% and the heat dissipation efficiency by 30%, effectively Prevent heat from spreading.
Full-time control of the fifth-generation battery management system: By using the latest generation of automotive-grade battery management system chips, all-weather data collection can be achieved 10 times per second, which is 100 times higher than the previous generation system, with 24 Full-time patrol mode with hourly coverage to monitor battery status.
When an abnormality is discovered, the battery rapid cooling system is immediately started to cool down the battery. The application of full-time patrol mode and abnormal self-rescue has redefined the standard of active safety of ternary lithium batteries.
