本发明公开了一种热失控处理系统和热失控处理方法,属于电池技术领域。该热失控处理系统包括电池冷却液管路、电机冷却液管路、检测模块和泄压阀,位于动力电池包内的电池冷却液管路通过电控三通阀与动力电池包内部连通;在动力电池包外的电池冷却液管路与电机冷却液管路的连接处设置有电控四通阀,电控四通阀用于切换电池冷却液管路与电机冷却液管路之间连通或封闭的状态;检测模块用于检测动力电池包内部的压力和温度;泄压阀设置于动力电池包内的设定高度处,设定高度小于电池单体的高度。快速降低动力电池包内的温度和压力,防止自燃爆炸的电池单体点燃其他电池单体,防止整个动力电池包发生自燃爆炸。

    The invention discloses a thermal runaway treatment system and a thermal runaway treatment method, and belongs to the technical field of batteries. The thermal runaway treatment system comprises a battery cooling liquid pipeline, a motor cooling liquid pipeline, a detection module and a pressure release valve, wherein the battery cooling liquid pipeline positioned in a power battery pack is communicated with the interior of the power battery pack through an electric control three-way valve; an electric control four-way valve is arranged at the joint of the battery cooling liquid pipeline and the motor cooling liquid pipeline outside the power battery pack, and is used for switching the communication or closing state between the battery cooling liquid pipeline and the motor cooling liquid pipeline; the detection module is used for detecting pressure and temperature in the power battery pack; the pressure release valve is arranged at a set height in the power battery pack, and the set height is smaller than the height of the single battery. The temperature and the pressure in the power battery pack are quickly reduced, so the spontaneous explosion battery monomer is prevented from igniting other battery monomers, and the spontaneous explosion of the whole power battery pack is prevented.
