The invention relates to a battery thermal management method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining historical operation data of a power battery of each vehicle in a historical time period, determining at least one specified working condition according to the historical operation data, and determining at least one specified working condition for each vehicle; and according to the corresponding historical average temperature of the vehicle under the specified working condition, a corresponding preset temperature threshold value of the vehicle under the specified working condition is adjusted, and a working condition temperature threshold value of the vehicle under each preset working condition is obtained, so that the working condition temperature threshold value of the vehicle under each preset working condition is obtained according to the running temperature of a target power battery of the vehicle and a target working condition temperature threshold value. And performing temperature management on the target power battery. According to the method, the working condition temperature threshold value of the vehicle under each preset working condition is obtained by adjusting the preset temperature threshold value according to the historical operation data, and the operation temperature of the power battery can be always controlled within a proper range, so that the operation temperature of the power battery is optimized, and the attenuation rate of the power battery is slowed down.

    本公开涉及一种电池的热管理方法、装置、存储介质和电子设备,该方法包括:获取每个车辆的动力电池在历史时间段内的历史运行数据,根据历史运行数据,确定至少一个指定工况,针对每个车辆,根据该车辆在指定工况下对应的历史平均温度,对该车辆在指定工况下对应的预设温度阈值进行调节,得到该车辆在每个预设工况下的工况温度阈值,以便根据该车辆的目标动力电池的运行温度和目标工况温度阈值,对目标动力电池进行温度管理。本公开通过利用历史运行数据,对预设温度阈值进行调节,得到车辆在每个预设工况下的工况温度阈值,能够将动力电池的运行温度始终控制在合适的范围内,从而优化动力电池的运行温度,减缓动力电池的衰减速率。
