The invention provides a control method of a charging pile, a controller of the charging pile and the charging pile. The method comprises the steps of obtaining a voltage value of an input end of a power module in an energy complementing process of the charging pile; determining whether the three-phase AC power supply fails according to the voltage value of the input end of the power module; and when it is determined that the three-phase alternating-current power supply has a fault, the switch module is controlled to be disconnected to stop energy compensation, and when the switch module is disconnected, the switch module is disconnected with the power module, and the power module does not charge the energy storage module. According to the scheme, in the charging pile energy supplementing process, the state of the three-phase alternating-current power supply can be recognized through the voltage value of the input end of the power module, whether the three-phase alternating-current power supply breaks down or not is determined, connection between the switch module and the power module is disconnected under the condition that the three-phase alternating-current power supply breaks down, and therefore energy supplementing on the charging pile can be stopped; therefore, the service life of the charging pile can be prolonged.

    本申请提供了一种充电桩的控制方法、充电桩的控制器和充电桩。该方法包括:在充电桩补能过程中,获取功率模块输入端的电压值;根据功率模块输入端的电压值确定三相交流电源是否故障;在确定三相交流电源故障的情况下,控制开关模块断开以停止补能,其中,在开关模块断开的情况下,开关模块与功率模块断开连接,功率模块不对储能模块进行充电。该方案中,在充电桩补能过程中,可以通过功率模块输入端的电压值识别三相交流电源的状态,确定三相交流电源是否故障,并在三相交流电源故障的情况下断开开关模块与功率模块的连接,这样可以停止对充电桩进行补能,以保护功率模块,进而可以提高充电桩的使用寿命。
