The invention discloses a vehicle battery thermal runaway control system and method and an electric vehicle. The system comprises: a detection module which is used for acquiring state information of a battery pack; a battery management module which is used for terminating a shutdown or dormancy state according to a preset frequency when the whole vehicle is shut down or dormant, performing thermal runaway judgment according to the state information, and sending a control signal to the whole vehicle control module if the thermal runaway of the battery pack is judged; a whole vehicle control module which is used for terminating a shutdown or dormant state according to the control signal and sending a cooling control signal to the cooling control module; and a cooling control module which cools the battery pack according to the cooling control signal. According to the technical scheme provided by the embodiment of the invention, the state information of the battery pack is detected when the electric vehicle stops or sleeps, and the temperature is controlled when the battery pack is in thermal runaway.
本发明公开了一种整车电池热失控控制系统、方法及电动汽车。其中,系统包括检测模块用于获取电池组的状态信息;电池管理模块用于当整车停机或休眠时根据预设频率终止停机或休眠状态,并根据所述状态信息进行热失控判断,若判断所述电池组热失控,则发送控制信号至整车控制模块;整车控制模块用于根据所述控制信号终止停机或休眠状态,并发送冷却控制信号至冷却控制模块;冷却控制模块根据所述冷却控制信号对所述电池组进行冷却处理。本发明实施例提供的技术方案,实现了电动汽车停机或休眠时,对电池组状态信息的检测以及电池组热失控时温度的控制。
