The invention discloses a thermal runaway protection method and device, a storage medium and an electric vehicle. The method comprises the following steps: determining a battery thermal runaway level based on a plurality of battery state parameters obtained by monitoring a plurality of battery thermal runaway sensors; determining other thermal runaway levels based on a plurality of equipment state parameters obtained by monitoring a plurality of fire sensors; the battery thermal runaway level and other thermal runaway levels are integrated, and the overall thermal runaway level of the equipment is determined; and under the condition that the overall thermal runaway level is the high level, determining whether to execute a protection measure for discarding the battery pack or not according to the duration of the overall thermal runaway level being the high level and the moving speed of the equipment. According to the scheme, the thermal runaway level can be accurately evaluated, personnel safety is effectively guaranteed in a mode of discarding the battery pack, the equipment explosion scale is reduced, and loss and maintenance cost are reduced.
本发明公开一种热失控的保护方法、装置、存储介质及电力车辆。其中,所述方法包括:基于监测若干电池热失控传感器所得的若干电池状态参数,确定电池热失控级别;基于监测若干火灾传感器所得的若干设备状态参数,确定其他热失控级别;综合电池热失控级别以及其他热失控级别,确定设备的整体热失控级别;在整体热失控级别为高级的情况下,综合所述整体热失控级别为高级的持续时长以及设备的移动速度,确定是否执行丢弃电池包的保护措施。该方案能够准确评估热失控级别,并以丢弃电池包的方式有效保障人员安全,减小设备燃爆规模,降低损耗及维修成本。
