The invention discloses a battery charging strategy determination method and device and a computer storage medium, and the method comprises the steps: charging a battery to different preset SOCs at at least one first charging rate, and determining the SOC lithium precipitation condition corresponding to each first charging rate; according to the SOC lithium precipitation condition corresponding to each first charging rate, a target charging rate in the at least one first charging rate and a target SOC corresponding to the target charging rate are determined, and the SOC lithium precipitation condition corresponding to the target charging rate indicates that a lithium precipitation phenomenon occurs when the battery is charged to at least one preset SOC at the target charging rate; according to the target charging rate, the battery is charged to the target SOC with at least one second charging rate, and a charging result corresponding to each second charging rate is obtained; and if the charging result corresponding to the second charging rate meets a preset condition, determining a charging strategy of the battery according to the second charging rate. Therefore, the determination time of the charging strategy can be shortened.
本发明公开了一种电池充电策略的确定方法、装置及计算机存储介质,该方法包括:以至少一个第一充电倍率将电池充电至不同预设SOC,并确定各第一充电倍率对应的SOC析锂情况;根据各第一充电倍率对应的SOC析锂情况,确定至少一个第一充电倍率中的目标充电倍率以及目标充电倍率对应的目标SOC,目标充电倍率对应的SOC析锂情况表示以目标充电倍率将电池充电至其中至少一个预设SOC时电池发生析锂现象;根据目标充电倍率,以至少一个第二充电倍率将电池充电至目标SOC,得到各第二充电倍率对应的充电结果;若第二充电倍率对应的充电结果满足预设条件,则根据第二充电倍率确定电池的充电策略。可见,实施本发明能够有利于缩短充电策略的确定时间。
