March, Guangqi Euan Releases the world’s first magazine battery system security technology (referred to as “magazine battery”), the industry first realizes three-yuan lithium battery full pack needle thorn, redefined three yuan lithium battery safety standards, and obtains inside and outside the industry Highly evaluation. The listing of “the first car” of the magazine battery “Aion Y is also proved from another angle, battery safety, is always one of the important considerations of consumers to buy new energy. On May 20, GAC ENA once again released phosphate (magazine battery) acupuncture test, refreshed the safety of iron phosphate battery safety.
The most strict national standard needle test, the highest safety phosphate battery
Previously, In order to verify the safety of the “magazine battery”, the Chief Expert of China Automobile Technology Research Center Co., Ltd., one of the national battery safety standards, Dr. Liu Shiqiang leads the team, and is equipped with a three-dimensional lithium battery that is equipped with a magazine battery system. The needle-hot diffusion test was carried out, and the historic breakthrough of three-dimensional lithium battery safety was achieved. This trial is compared using lithium iron phosphate (ordinary batteries) and lithium iron phosphate (magazine batteries). The test conditions also chose the most demanding test conditions of the national standard, that is, the acupuncture test is performed at the 8 mm thick steel needle diameter and 100 percent SOC power.
Test results show that the voltage drop in the steel needle after the steel needle is pierced in the steel needle, and there is a voltage drop. The temperature rise, the maximum temperature is 329.4 ° C, and there is a smoke phenomenon, which lasts for 16 minutes; lithium iron phosphate (magazine battery) is thorough, the highest temperature is only 51.1 ° C, still 48 hours, monomer The voltage drops to 0V, the temperature is reduced to room temperature, and there is no smoke, no fire and explosion, the battery pack state is stable. Open the battery system housing, its internal structure is intact.
From the perspective of test results, the iron phosphate lithium iron phosphate, which is equipped with a magazine battery system, has a common whole package, does not smoke, and the temperature is only 51.1 ° C. It is currently the optimal power battery in needle fever, and refreshes the safety and new height of lithium iron phosphate battery. 
Termination of the route, comprehensively meet the needs of users under different travel scenes
Sany-lithium in the same life (600km), the weight of the battery It can weigh more than 100-150kg than other lithium iron phosphate batteries, which is equivalent to the weight of 1.5-2 adults. The lightweight of the whole vehicle can make the control performance and acceleration performance of the vehicle, suitable for the pursuit of driving control performance and long battery customers; second, the dual lithium battery is high in low temperature environment than phosphate battery high About 10%, a longer battery life is achieved in winter. Lithium iron phosphate has 4000+ times of ultra-high cycle life, twice as many other three-dimensional lithium batteries, while cost is lower, suitable for high-frequency charging needs. Thus, the two technical routes of lithium iron phosphate cells, and the three-dimensional lithium batteries can meet the different travel needs of users.
Although the integrated performance of the three-dimensional lithium battery is stronger, the thermal stability of lithium iron phosphate battery is better, and there is a better safety performance. Therefore, in the past, everyone has been discussing the three-dimensional lithium battery and lithium iron phosphate batteries. The emergence of the magazine battery solves the challenge of selecting a three-dimensional lithium battery or a lithium iron phosphate battery. The magazine battery system security technology has ultra-high heat-resistant and stable battery, super-insulating battery safety cabin, speed cooling speed-cooled system, and four major core technology, etc., which can be controlled by the fifth-generation battery management system. Safety and safety of battery cells, passive safety, and active safety prevention and control three major aspects improve battery system security performance. The magazine battery is the only technology that is the only two major technical route battery safety at the same time at the same time, both of the three-dimensional lithium and lithium iron phosphate.
The appearance of the cartoon battery allows different chemical architectural batteries to achieve safety, and propose a new solution for battery safety for the industry. ProblemRoad, ending the dispute of industry technology routes, fully meets the needs of users under different travel scenes.
The security is never endless, and Guangzhou Automobile Emian is still practicing the initial heart of mobile travel, including academic institutions such as Joint Tsinghua University. In order to promote the progress of the overall industry battery safety technology, the power of GAC ENA will bring safe products to users.
