The embodiment of the invention provides a vehicle battery thermal management method and device, electronic equipment and a storage medium. The temperature rise rate of a battery is determined by responding to starting operation of a battery thermal management function; the maximum temperature value of the battery is determined according to the heating rate, and the corresponding estimated charging current when the battery temperature reaches the maximum temperature value is determined; and after the actual charging current of the battery reaches the maximum charging current of the battery and the estimated charging current is smaller than the charging current threshold value corresponding to the maximum temperature value, the battery thermal management function is closed, so that the self-adaptive control of the start and stop of the battery thermal management function is realized. The charging efficiency of the power battery is prevented from being influenced by long-time operation of the battery thermal management function, the overall energy consumption of the battery thermal management function is reduced, the charging effect of the power battery is improved, and the charging time of the power battery is shortened.
本发明实施例提供了一种车辆电池热管理方法及装置、电子设备、存储介质,通过响应于电池热管理功能的启动操作,确定电池的升温速率;从而根据升温速率确定电池的温度最大值,并确定电池温度达到温度最大值时对应的预估充电电流;进而在电池的实际充电电流达到电池的最大充电电流之后,且,预估充电电流小于温度最大值对应的充电电流阈值的情况下关闭电池热管理功能的方式,实现了电池热管理功能启停的自适应控制;避免了电池热管理功能的长时间运行影响动力电池的充电效率,降低了电池热管理功能的整体能耗,提升了动力电池的充电效果,缩短了动力电池的充电时间。
