The invention discloses a battery thermal management abnormity early warning method and device, electronic equipment and a medium, and the method comprises the steps: obtaining the state data of a vehicle every one collection period after the vehicle is started; for each acquisition period, the battery temperature of the vehicle is marked based on the state data in the acquisition period, a temperature label set is obtained, the temperature label set comprises battery temperature labels corresponding to the multiple acquisition periods, and the battery temperature labels comprise overtemperature labels and non-overtemperature labels; based on the temperature label set, whether thermal management abnormity exists in the vehicle battery is judged; and if the thermal management of the vehicle battery is abnormal, performing thermal management abnormity early warning. By monitoring the state data of the vehicle in real time, the risk of thermal runaway of the battery is found in time, remote monitoring and early warning are carried out, and therefore safety accidents caused by thermal runaway of the vehicle battery are effectively prevented.

    本发明公开了一种电池热管理异常预警方法、装置、电子设备及介质,所述方法包括:在车辆启动后,每间隔一个采集周期获取车辆的状态数据;分别针对每个采集周期,基于采集周期下的状态数据对车辆的电池温度进行标记,得到温度标签集合,其中,温度标签集合包括多个采集周期分别对应的电池温度标签,电池温度标签包括温度过高标签以及非温度过高标签;基于温度标签集合,判定车辆电池是否存在热管理异常;若车辆电池为热管理异常,则进行热管理异常预警。通过实时监测车辆的状态数据,及时发现电池热失控的风险,进行远程监控和预警,从而有效预防车辆电池热失控引发的安全事故。
