The invention provides a charging pile, and a charging control method and circuit thereof. The power demand of a vehicle is determined in real time after a vehicle is connected with the charging pile,and the automatic recognition of the power demand change of a vehicle end in a whole vehicle charging process is achieved; then, according to the power demand of the vehicle, the number of maneuvering power modules to be distributed in the charging pile is determined, the number of the maneuvering power modules needing to be distributed is determined in real time according to the power demand, and the power demand of the vehicle at different time in the charging process is expected to be met; and finally, when the number of the maneuvering power modules to be distributed is greater than or equal to 1, the output ends of the maneuvering power modules with the corresponding number are controlled to be connected to the input end of a charger connected with the vehicle, the charger connectedwith the vehicle charges the vehicle through a fixed power module and the maneuvering power module which are connected with the charger, so that the output power of the charging pile is matched with the power demand of the vehicle in the charging process in real time, the charging pile is promoted to keep a rated current state, and the loss of the charging pile is reduced.

    本发明提供一种充电桩及其充电控制方法和电路,在车辆连接充电桩之后,实时确定车辆的功率需求,实现在整车充电过程中自动识别车端功率需求变化;然后根据车辆的功率需求,确定充电桩内机动功率模块的待分配数量,实现实时根据功率需求确定需要分配的机动功率模块数量,以期满足车辆在充电过程中不同时间的功率需求;最后当待分配的机动功率模块数量大于等于1时,控制相应数量的机动功率模块的输出端连接至车辆所接连充电器的输入端,使车辆所接连充电器通过自身所连接的固定功率模块和机动功率模块共同为车辆充电,使得充电桩的输出功率实时匹配车辆充电过程的功率需求,促使充电桩保持额定电流状态,降低了充电桩的损耗。
