The invention belongs to the technical field of vehicle batteries, and discloses a battery thermal runaway diagnosis method, device and equipment and a storage medium. The method comprises the steps that the current state of a vehicle is obtained, and whether the current state is a power-on state or not is judged; when the vehicle is in the power-on state, first parameter information collected by a composite sensor of the vehicle is obtained; fault matching is performed in a first thermal runaway fault table according to the first parameter information to obtain a fault matching result; and when the fault matching result is that the matching is successful, the condition that the vehicle has a thermal runaway fault is judged. According to the invention, whether the thermal runaway of the vehicle occurs is judged according to the current state of the vehicle and the first parameter information collected by the composite sensor, so that compared with an existing mode of judging whether the thermal runaway of the vehicle battery pack occurs according to the voltage or temperature of the battery pack, the thermal runaway fault of the vehicle can be identified more accurately, and the safety of a driver and passengers is protected.

    本发明属于车辆电池的技术领域,公开了一种电池热失控诊断方法、装置、设备及存储介质。该方法包括:获取车辆的当前状态,判断所述当前状态是否为上电状态;在所述车辆处于上电状态时,获取所述车辆的复合型传感器采集的第一参数信息;根据所述第一参数信息在第一热失控故障表中进行故障匹配,获得故障匹配结果;在所述故障匹配结果为匹配成功时,判定所述车辆为热失控故障。由于本发明是根据车辆的当前状态和复合型传感器采集的第一参数信息判断车辆是否发生热失控,相对于现有的根据电池包的电压或者温度判断车辆电池包是否发生热失控的方式,本发明上述方式能够更加准确的识别车辆的热失控故障,保护驾乘人员的安全。
