The invention discloses a current switching method and system for quick charging of a battery, an electronic device and a storage medium. The method comprises the following steps: detecting whether the battery is in a quick charging state or not; if the battery is in the fast charging state, obtaining a current state parameter of the battery; calculating a target charging current of the battery by using the state parameters; acquiring the actual output current of the charging pile; calculating the current request charging current of the battery by using the target charging current and the actual output current; and outputting the request charging current to the charging pile, and switching the actual output current of the charging pile by using the request charging current. According to the technical scheme provided by the invention, the technical problem that the battery management system of the charging pile in the prior art cannot be compatible with the response of all the charging piles to the request current so as to possibly cause false alarm of faults and stop of quick charging can be solved.

    本发明公开了一种电池快充的电流切换方法、系统、电子装置和存储介质,方法包括:检测电池是否处于快充状态;若电池处于快充状态,则获取电池当前的状态参数;利用状态参数计算电池的目标充电电流;获取充电桩的实际输出电流;利用目标充电电流、实际输出电流计算电池当前的请求充电电流;将请求充电电流输出至充电桩,利用请求充电电流切换充电桩的实际输出电流。本发明所提供的技术方案能够解决现有技术中充电桩的电池管理系统无法兼容所有充电桩对请求电流的响应,可能导致误报故障,停止快充的技术问题。
