The invention discloses a power battery charging method, device and equipment and a medium, and the method comprises the steps: monitoring the actual charge state of a target battery in the charging process of the target battery; when the actual charge state is smaller than a preset charge state, determining a current actual charging stage of the target battery according to the actual charge state; determining a target limit charging rate corresponding to the actual charging stage according to the actual charging stage and a corresponding relation between the charging stage and the limit charging rate; and determining an actual charging rate according to the target limit charging rate, and controlling the target battery to be charged at the actual charging stage according to the actual charging rate. Charging is carried out within the range smaller than or equal to the limit charging multiplying power, the obvious polarization phenomenon can be avoided, the polarization degree can be reduced, in other words, on the premise of the low polarization degree, the charging multiplying power is increased as much as possible, the charging duration is shortened, the charging efficiency is improved, and meanwhile the charged electric quantity is increased.
本发明公开了一种动力电池充电方法、装置、设备和介质,包括:在目标电池充电过程中,监测目标电池的实际荷电状态;当实际荷电状态小于预设荷电状态时,根据实际荷电状态确定目标电池当前所处的实际充电阶段;根据实际充电阶段和充电阶段与极限充电倍率之间的对应关系,确定实际充电阶段对应的目标极限充电倍率;根据目标极限充电倍率确定实际充电倍率,并控制目标电池在实际充电阶段按照实际充电倍率充电。本发明在小于或等于极限充电倍率的范围内充电,能避免发生明显的极化现象,降低极化程度,也就是在低极化程度的前提下尽可能增大充电倍率,缩短充电时长,提高充电效率,同时提高充入的电量。
