The invention provides a system for preventing thermal runaway of a battery pack, and the system comprises the battery pack which comprises a battery module and a battery management unit, and the battery management unit sends a thermal runaway signal to a whole vehicle control unit after monitoring thermal runaway; the whole vehicle control unit sends a control signal after receiving the thermal runaway signal; an air inlet of the vacuum pump is in fluid communication with an exhaust port of the battery pack through the pipeline, an exhaust port of the vacuum pump is in fluid communication with a gas outlet of the vehicle through the pipeline to form a first flowing channel, and the vacuum pump sucks gas in the battery pack through the first flowing channel and discharges the gas to the gas outlet. The system can quickly and effectively relieve thermal runaway in the battery pack. In addition, the invention further provides a method for preventing thermal runaway of the battery pack and a vehicle comprising the system.
本公开提供了一种用于阻止电池包热失控的系统,包括:电池包,其包括电池模组、以及电池管理单元,电池管理单元在监测到热失控后将热失控信号发送给整车控制单元;整车控制单元,整车控制单元在接收到热失控信号后发送控制信号;真空泵以及管道,真空泵的进气口经由管道与电池包的排气口流体连通并且真空泵的排气口经由管道与车辆的气体出口流体连通以形成第一流动通路,真空泵通过第一流动通路抽吸电池包中的气体并排放到气体出口。该系统能够快速、有效地缓解电池包内的热失控。此外,本公开还提供了一种用于阻止电池包热失控的方法以及包括该系统的车辆。
