The invention discloses a battery thermal runaway monitoring method, which comprises the following steps that: when a battery management system is in a dormant state, a pressure monitoring and awakening module monitors the opening and closing of a pressure valve; wherein the pressure valve is used for being opened when the internal pressure of the closed environment where the battery module is located is larger than a preset pressure threshold value; and when it is monitored that the pressure valve is opened, the pressure monitoring and awakening module sends an awakening signal to the batterymanagement system so as to awaken the battery management system to carry out thermal runaway early warning operation. The invention also discloses a battery thermal runaway monitoring device, a battery thermal runaway monitoring system and a vehicle. By adopting the method of the invention, the thermal runaway of the battery can be effectively monitored when the battery management system is in the dormant state.

    本发明公开了一种电池热失控监控方法,包括:在电池管理系统处于休眠状态下,压力监测和唤醒模块监测压力阀的开闭;其中,所述压力阀用于在受到的电池模组所处的封闭环境的内部压力大于预设的压力阈值时打开;当监测到所述压力阀打开时,所述压力监测和唤醒模块向所述电池管理系统发出唤醒信号,以唤醒所述电池管理系统进行热失控预警操作。本发明还公开了一种电池热失控监控装置、系统及车辆。采用本发明实施例,能够在电池管理系统处于休眠状态下对电池的热失控进行有效监控。
