The invention discloses a charging pile capable of performing charging power compensation and a charging method thereof. The charging pile comprises a power distribution module, a detection module anda compensation module. The method comprises the steps of: detecting the residual electric quantity of a to-be-charged electric vehicle connected with the first charging pile, and automatically distributing required charging power to the charging gun; detecting the output charging power of any charging gun in a working state; and if the output charging power of any charging gun cannot reach the corresponding required charging power, allowing the first charging pile to send a compensation signal to the second charging pile to request charging power compensation, and allowing the second chargingpile to respond to the compensation signal to complete power compensation. According to the invention, the idle current is compensated to the charging gun to be required, so that the power of the charging gun can reach the required charging power. The charging power of the charging gun can be automatically adjusted according to the residual electric quantity of the electric vehicle to protect thebattery safety of the electric vehicle.
本发明公开一种可进行充电功率补偿的充电桩以及充电方法,包括功率分配模块、检测模块以及补偿模块;检测与第一充电桩连接的待充电电动汽车的剩余电量,并自动为充电枪分配需求充电功率;检测处于工作状态的任一充电枪的输出充电功率;若任一充电枪的输出充电功率达不到相对应的需求充电功率,则第一充电桩发出补偿信号到第二充电桩请求充电功率补偿,第二充电桩响应补偿信号从而完成功率补偿。本发明通过将空闲的电流补偿到待需求的充电枪中,使得充电枪的功率能达到需求充电功率。同时能根据电动汽车的剩余电量自动调整充电枪的充电功率,以保护电动汽车的电池安全。
