The invention relates to a thermal runaway detection method and device, electronic equipment and a storage medium, the detection device comprises a detection unit and a battery management system of a vehicle, and the detection unit comprises a plurality of control modules which are sequentially connected in series; the plurality of control modules are respectively arranged on a plurality of battery cells of at least one battery module of a power supply unit of the vehicle, the temperature control switch is used for acquiring the current temperature of the corresponding battery cell, and under the condition that the current temperature is not less than a set temperature threshold value, the temperature control switch is switched from an open state to a closed state; and the battery management system is used for determining a detection result of the power supply unit based on the obtained resistance of the detection loop. According to the invention, the plurality of control modules are respectively arranged on the plurality of battery cells, so that whether the power supply unit is subjected to thermal runaway or not is judged according to the temperature of any battery cell, the detection speed is improved, the flexibility and accuracy of the detection device are improved, and meanwhile, space resources are saved.

    本申请涉及一种热失控检测方法及装置、电子设备和存储介质,检测装置包括检测单元和所述车辆的电池管理系统,其中:所述检测单元包括依次串联的多个控制模块,所述多个控制模块分别设置在所述车辆的供电单元的至少一个电池模组的多个电芯上,所述温控开关,用于获取对应电芯的当前温度,在所述当前温度不小于设定的温度阈值的情况下,从所述打开状态切换为关闭状态;所述电池管理系统,用于基于获取的所述检测回路的电阻,确定所述供电单元的检测结果。本申请由于将多个控制模块分别设置在多个电芯上,实现了根据任一电芯的温度来判断供电单元是否发生热失控,在提高了检测速度的同时还提高了检测装置的灵活度与准确度,同时,节省了空间资源。
