The invention relates to a method and a device for identifying misinformation of thermal runaway of a vehicle battery cell, a storage medium and a vehicle. The method belongs to the field of vehicle-mounted batteries, and comprises the following steps: in response to receiving a thermal runaway alarm, acquiring current battery cell temperatures and battery cell voltages of a plurality of sub-modules in a battery module; determining whether the battery module has a heat conduction phenomenon according to the temperatures of the plurality of battery cells; under the condition of determining thatthe battery module does not generate the heat conduction phenomenon, determining whether the voltage of the battery module is abnormal according to the voltages of the plurality of battery cells; anddetermining that the thermal runaway alarm is a false alarm when it is determined that the battery module does not have the abnormal voltage. According to the method provided by the embodiment of theinvention, whether the received thermal runaway alarm is a false alarm or not can be identified without disassembling the battery by acquiring the battery cell temperature and the battery cell voltage of each sub-module of the battery module, so that the risk of traffic accidents possibly caused when the thermal runaway alarm is the false alarm is avoided.

    本公开涉及一种识别车辆电芯热失控的误报的方法、装置、存储介质及车辆。属于车载电池领域,所述方法包括:响应于接收到热失控报警,获取电池模组内多个子模组当前的电芯温度以及电芯电压;根据多个所述电芯温度确定所述电池模组是否发生热传导现象;在确定所述电池模组未发生热传导现象的情况下,根据多个所述电芯电压确定所述电池模组是否存在电压异常;在确定所述电池模组不存在电压异常的情况下,确定所述热失控报警为误报警。本公开实施例提供的技术方案能够通过获取电池模组各个子模组的电芯温度以及电芯电压,无需拆解电池即可识别接收到的热失控警报是否为误警报,避免了在热失控警报是误警报时可能导致交通事故的危险。
