The invention belongs to the technical field of charging piles, and provides a charging pile power module current sharing method and a charging pile in order to solve the problem that output current of a traditional charging pile power module is not uniform. The charging pile comprises a current sharing circuit and N power modules, and in the process of executing the current sharing method for the power modules of the charging pile, the current sharing circuit obtains sampling voltage of output voltage of the power modules and averages the sampling voltage to obtain average voltage; and the power supply module obtains the average voltage, and adjusts the output voltage of the power supply module according to the average voltage and the sampling voltage, so that the output current of the power supply module is in a current range with the average current as the center and the preset value as the radius. Therefore, the output current of the N power supply modules is ensured to be in the same current range, current-sharing output of the N power supply modules is realized, and no-load or overload work of the power supply modules is avoided.

    本申请属于充电桩技术领域,为了解决传统充电桩电源模块输出电流不均匀的问题,提供一种充电桩电源模块均流方法和充电桩。本申请充电桩包括均流电路和N个电源模块,在执行充电桩电源模块均流方法的过程中,均流电路获取电源模块的输出电压的采样电压,并对采样电压进行平均获取平均电压;电源模块获取平均电压,并根据平均电压和采样电压调节电源模块的输出电压,以使电源模块的输出电流在以平均电流为中心,以预设值为半径的电流范围内。从而保证N个电源模块的输出电流都在同一电流范围内,实现N个电源模块均流输出,避免出现电源模块空载或超负荷工作。
