New energy car battery pack cut off high pressure for 1 second
The “Key Technology for Power Battery Systems for New Energy Vehicles†that won the first prize for technical inventions can make the battery pack of new energy vehicles cut off power within 1 second in case of a collision.
The project was completed by Chongqing Changan New Energy Automobile Co., Ltd., Chongqing University of Posts and Telecommunications and Chongqing Changan Automobile Co., Ltd. Through many years of research, they have developed high-security, high-economy, high-reliability power battery system technology, which has increased the safety coverage of power battery systems from 13% to 97%.
They also invented the high-voltage system insulation detection and verification technology. In the event of a collision, the battery system will first alarm, and then quickly cut off the relay and turn off the power supply, and decompose the high voltage of more than 300 volts of the battery system into low voltage to reduce the explosion. Burning risk. It only takes 1 second from the alarm to cut off the power, while the past technology requires at least 6 seconds. Now this technology has been widely used in Chang'an series of new energy vehicles such as Jiexun, CX30, C204, Zhixiang and others. New energy vehicles such as Schaeffler, Changan Suzuki, Changhe Hefei, and Geely also used battery packs independently developed by Changan.
