The invention provides a battery thermal runaway early warning method, device and equipment. The battery thermal runaway early warning method comprises the following steps: acquiring charging data in a charging process; determining whether a single battery has a thermal runaway risk or not according to the charging data; when it is determined that the target single battery has the thermal runaway risk, corresponding early warning information is generated; wherein the target single battery is at least one of the single batteries. According to the scheme, the charging data in the charging process is obtained, whether the single battery has the thermal runaway risk or not is judged according to the charging data, and the corresponding early warning information is generated under the condition that at least one single battery, namely the target single battery has the thermal runaway risk, so that feature recognition of the vehicle data can be realized; therefore, whether the internal short-circuit thermal runaway risk exists in the battery is judged according to the vehicle data.
本发明提供了一种电池热失控预警方法、装置和设备,所述电池热失控预警方法包括:获取充电过程中的充电数据;根据所述充电数据,确定是否有单体电池存在发生热失控风险;在确定目标单体电池存在发生热失控风险的情况下,生成对应的预警信息;其中,所述目标单体电池为所述单体电池中的至少之一。本发明方案,通过获取充电过程中的充电数据,并根据充电数据判断是否有单体电池存在发生热失控风险,在有至少一个单体电池,即目标单体电池存在发生热失控风险的情况下,生成对应的预警信息,可以实现对车辆数据进行特征识别,进而实现根据车辆数据判定电池内是否存在内短路热失控风险。
