The invention discloses a battery thermal runaway processing method and device, electronic equipment and a storage medium. The method comprises the steps that whether state parameters of a battery of a vehicle meet any early warning state combination condition or not is detected; the early warning state combination condition comprises an early warning condition of one basic state parameter and an early warning condition of one corresponding sub state parameter; if any early warning state combination condition is satisfied, determining that thermal runaway of the battery occurs; if the current vehicle is in the dormant state, thermal runaway fault information is reported; if the vehicle is in the non-dormant state, vehicle evacuation alarm processing is carried out, and thermal runaway fault information is reported; if the high-voltage relay of the battery is in the closed state, judging whether the vehicle speed is smaller than a preset speed; if the speed is smaller than the preset speed, directly disconnecting a high-voltage relay of the battery; if the speed is not smaller than the preset speed, the allowable power of the vehicle is reduced to zero according to the speed corresponding to the current allowable power of the vehicle, and after the allowable feedback power of the vehicle is set to zero, a high-voltage relay of the battery is disconnected.
本申请公开了一种电池热失控处理方法及装置、电子设备、存储介质,所述方法包括:检测车辆的电池的状态参数是否满足任意一个预警状态组合条件;预警状态组合条件包括一个基础状态参数的预警条件和对应的一个子状态参数的预警条件;若满足任意一个预警状态组合条件,确定电池发生热失控;若当前车辆处于休眠状态,上报热失控故障信息;若车辆处于非休眠状态,进行撤离车辆告警处理及上报热失控故障信息;若电池的高压继电器为闭合状态,判断车速是否小于预设速度;若小于预设速度,直接断开电池的高压继电器;若不小于预设速度,按照车辆的当前许用功率对应的速率将车辆的许用功率降为零,且将车辆的许用回馈功率置为零后,断开电池的高压继电器。
