The invention provides a vehicle thermal runaway early warning method and device, a vehicle and a storage medium. The method includes: determining a current state of the battery cell; if the current state is the target state, abnormal state information of the battery unit is detected; if the abnormal state information detected in the preset time period comprises at least two kinds of abnormal state information in voltage state abnormal information, temperature state abnormal information and communication state abnormal information, it is determined that the vehicle has a thermal runaway risk, and the vehicle is controlled to output thermal runaway early warning information, the voltage state abnormal information comprises voltage abnormal information, voltage sampling open-circuit information and voltage sampling invalid information, and the temperature state abnormal information comprises temperature abnormal information, temperature difference abnormal information and temperature validity abnormal information. According to the method, the vehicle thermal runaway early warning effect is improved.

    本申请提供一种车辆热失控预警方法、装置、车辆及存储介质。该方法包括:确定电池单元的当前状态;若当前状态为目标状态,则检测电池单元的异常状态信息;若在预设时间段内检测到的异常状态信息包括电压状态异常信息、温度状态异常信息以及通讯状态异常信息中的至少两种异常状态信息时,则确定车辆存在热失控风险,并控制车辆输出热失控预警信息,其中,电压状态异常信息包括电压异常信息、电压采样断路信息、以及电压采样无效信息,温度状态异常信息包括温度异常信息、温差异常信息、以及温度有效性异常信息。本申请的方法,提高了车辆热失控预警的效果。
