In March this year, Guangqi Yan’s heavy release of the world’s first magazine battery system security technology (referred to as “magazine battery”), the industry first realizes the three-yuan lithium battery, the whole package needle can’t afford fire, redefine three yuan lithium Battery safety standards and obtain high evaluation inside and outside the industry. 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.
most Strict national standard needle test, the highest safety phosphate battery
In order to verify the security of “magazine battery”, China Automotive Technology Research Center Co., Ltd. chief Expert, one of the national battery safety standards, Dr. Liu Shiqiang, led the team, and the three-dimensional thermal diffusion test of the three-dimensional lithium battery equipped with the magazine battery system security technology
, achieving three-dimensional lithium battery safety Historical breakthrough. 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
8mm thick steel needle diameter and 100 percent SOC power.
[123 The test results show that the lithium iron phosphate (ordinary battery) will be packed after the steel needle puncture the battery, and the temperature is lowered, the temperature rise is phenomenon, the maximum temperature is
329.4 ° C, and there is a smoke phenomenon, For 16 minutes; after lithium iron phosphate (magazine battery) is thorough, the maximum temperature is only 51.1 ° C, still 48 
hours, the monomer voltage drops to
0V, the temperature is reduced to room temperature, and No smoke, no fire and fireExplosive phenomenon, battery pack state is stable. Open the battery system housing, its internal structure is intact.
[123 From the experimental results, the iron phosphate of the magazine battery system security technology is relatively generally packaged, and the temperature is not smoking and the temperature is only
51.1 ° C, which is the most in the premise of the detection of the thermal out-of control. Excellent power battery, refreshes the safety new height of lithium iron phosphate battery.
The dispute of the end of the route, comprehensively meet the needs of users under different travel scenes
three yuan lithium in the same life (
600km
In the case, the weight of the battery pack is over
100-150kg
, which is equivalent to
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%
will achieve longer battery life in winter. Lithium phosphate has
4000+ ultra-high cycle life, two times the other three-yuan lithium battery, while the cost is lower, suitable for customers with high frequency charging requirements. 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. The battery is safe and improved, passive safety, and three major aspects of active safety prevention and control.Improve battery safety 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 Let the different chemical system batteries have realized the safety of the fire, put forward a new solution for the industry’s idea, ending the industry technology route, fully meet the needs of users under different travel scenes.
[123 ] Safety is never endless, GAC Eman continues to practice the brand initial heart, including mobile travel, including Joint Tsinghua University, and contribute to the progress of the overall industry battery safety technology, the power of Guangqi Yan, Give users a safe product.
