The invention provides a charging pile and a charging control method and circuit thereof. The method comprises the steps of determining the power demand of a connected vehicle in real time according to sampling information of a corresponding DC/DC power module in the charging pile after the vehicle is connected with the charging pile so as to achieve the purpose of accurately grasping the chargingpower change of the vehicle in a charging process; judging whether the power demand of the vehicle exceeds a power upper limit value of the corresponding DC/DC power module or not; if the power demand of the vehicle exceeds the power upper limit value of the corresponding DC/DC power module, controlling the output end of an AC/DC power module in the charging pile to be connected to the input endof a charger connected with the vehicle, so that the AC/DC power module and the corresponding DC/DC power module jointly charge the connected vehicle, and then supplementary power can be provided forthe vehicle through the AC/DC power module existing in the charging pile when the power of the corresponding DC/DC power module is insufficient so as to improve the charging efficiency of the chargingpile for the vehicle.

    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,根据充电桩内对应DC/DC功率模块的采样信息,实时确定连接车辆的功率需求,实现在充电过程中准确把握此车辆的充电功率变化;判断车辆的功率需求是否超过对应DC/DC功率模块的功率上限值;若车辆的功率需求超过对应DC/DC功率模块的功率上限值,则控制充电桩内AC/DC功率模块的输出端连接至车辆所连接充电器的输入端,使AC/DC功率模块与对应DC/DC功率模块共同为连接车辆充电,进而能够在对应DC/DC功率模块的功率不足时,通过充电桩内本身存在的AC/DC功率模块为车辆提供补充功率,以提高充电桩对于车辆的充电效率。
