The invention discloses an anti-overcharge method, device and equipment for a power battery and a medium, and the method comprises the steps: continuously monitoring whether the power battery enters a charging mode again or not under the condition that the power battery and the charging equipment are not disconnected after the charging process of the power battery is completed and the charging is stopped, and if the power battery enters the charging mode again, stopping the charging of the power battery; if yes, monitoring the actual charging amount stored after the power battery is recharged; if the actual charging amount is larger than or equal to the overcharge threshold value, the charging loop of the power battery is controlled to be disconnected, and then the overcharge phenomenon of the power battery is intervened in time. According to the invention, the charging loop can be disconnected before the service life of the power battery has a large negative effect, so that the probability of continuous charging after the power battery is fully charged is reduced to a certain extent, namely, the probability of an overcharge phenomenon of the power battery is reduced, the probability of shortening the service life of the power battery due to overcharge is greatly reduced, and the service life of the power battery is prolonged. And the service life of the power battery is prolonged.

    本发明公开了一种动力电池的防过充方法、装置、设备和介质,包括:在动力电池完成充电过程且停止充电后,在动力电池与充电设备之间未断开连接的情况下,持续监测动力电池是否再次进入充电模式,若监测动力电池再次进入充电模式后,则监测动力电池复充后存储的实际充入量;若实际充入量大于或等于过充阈值,控制动力电池的充电回路断开,进而及时干预动力电池发生过充现象。本发明可以在对动力电池的寿命造成较大负面影响之前断开充电回路,在一定程度上降低了动力电池在充满电后继续充电的几率,即降低动力电池出现过充现象的几率,也就大大降低了动力电池因过充导致寿命缩短的几率,延长了动力电池的使用寿命。
