The invention provides a thermal management method and device for a battery pack, a vehicle and a storage medium, and the method comprises the steps: judging whether the battery pack is aged or not based on the actual performance data of the battery pack of the vehicle in a use process and the original performance data of the battery pack when the battery pack is not used; under the condition that it is determined that the battery pack is aged, the temperature correction amount for conducting heat management on the battery pack is determined; and adjusting a thermal management strategy of the battery pack based on the temperature correction amount so as to maintain the charge-discharge performance of the battery pack. According to the method, when the battery pack is aged, the temperature correction amount can be determined to adjust the thermal management strategy of the battery pack, the influence of the aging of the battery pack on the charge and discharge performance is considered, the consideration is more comprehensive, and the charge and discharge performance of the battery pack can be maintained under the condition that the battery pack is aged.

    本申请提供了一种电池包的热管理方法、装置、车辆和存储介质,该方法包括:基于车辆的电池包在使用过程中的实际性能数据和未使用时的原始性能数据,判断电池包是否发生老化;在确定电池包发生老化的情况下,确定对电池包进行热管理的温度修正量;基于温度修正量,调整电池包的热管理策略,以维持电池包的充放电性能。该方法能够在电池包老化的时候,确定温度修正量来调整电池包的热管理策略,考虑到了电池包老化对充放电性能的影响,考虑的更加全面,实现了在电池包出现老化的情况下也能维持电池包的充放电性能。
