The invention discloses a power battery charging method, device and equipment and a medium, and the method comprises the steps: detecting the actual capacity and actual voltage of a power battery in the charging process of the power battery; according to at least one parameter of the actual capacity and the actual voltage, determining a target capacity and a target voltage for triggering the jump of the charging current of the power battery; and if the actual capacity reaches the target capacity or the actual voltage reaches the target voltage, controlling the charging current of the power battery to skip, so that the power battery continues to be charged according to the skipped charging current. According to the invention, the probability that the charging current of the power battery exceeds the maximum bearing capacity corresponding to the current stage can be reduced, the probability that the lithium precipitation phenomenon occurs in the power battery is reduced, the safety and the stability of the power battery in the charging process are improved, and the service life of the power battery is prolonged to a certain extent.

    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:在动力电池充电过程中,检测动力电池的实际容量和实际电压;根据实际容量和实际电压中的至少一个参数,确定用于触发动力电池的充电电流发生跳转的目标容量和目标电压;若实际容量达到目标容量,或者实际电压达到目标电压,控制动力电池的充电电流发生跳转,使得动力电池按照跳转后的充电电流继续充电。本发明可以降低动力电池的充电电流超过当前阶段对应的最大承受能力的几率,降低动力电池出现析锂现象的几率,提高动力电池在充电过程中的安全性和稳定性,也在一定程度上延长了动力电池的使用寿命。
