The embodiment of the invention provides a current control method and device for slow charging. The method comprises the following steps: obtaining a current corresponding to the charging capability of a charging pile, a current corresponding to the transmission capability of a cable, and a current corresponding to the characteristics of a high-voltage battery when a vehicle is detected to enter aslow charging mode; selecting the minimum value from the current corresponding to the charging capacity of the charging pile, the current corresponding to the cable transmission capacity and the current corresponding to the characteristics of the high-voltage battery as target current; obtaining the actual current of the slow charging mode, and taking the difference between the target current andthe actual current as the control target current; and generating an additional current, and adjusting the control target current through the additional current to make the numerical value of the control target current be 0. By the adoption of the method, the charging current can be accurately adjusted in the slow charging process, and the situations that the charging time is prolonged and the overcharging risk exists are avoided.

    本发明实施例提供一种慢充充电的电流控制方法及装置,所述方法包括:检测到车辆进入慢充充电模式时,获取充电桩充电能力对应电流、电缆传输能力对应电流和高压电池特性对应电流;从充电桩充电能力对应电流、电缆传输能力对应电流和高压电池特性对应电流中选择最小值作为目标电流;获取慢充充电模式的实际电流,根据目标电流和实际电流的差值作为控制目标电流;生成附加电流,并通过附加电流对控制目标电流进行调整,使控制目标电流的数值为0。采用本方法能够在慢充充电的过程中精准的对充电电流进行调整,避免了充电时间延长和存在过充风险的情况发生。
