The invention provides a control circuit and a control method for reducing standby power consumption of an old charging pile, and belongs to the field of electric vehicle charging piles. The control circuit comprises an alternating current contactor and an information transfer and control unit, a normally open contact of the alternating current contactor is used for being connected between a power grid and the input end of a power module of the old charging pile in series, and the information transfer and control unit is used for obtaining the state of the charging pile from information sent by a main controller of the old charging pile to a platform interaction terminal and controlling a coil of the alternating current contactor to be electrified when the charging pile is in a charging state, so as to enable the power module to be electrified, and controlling the coil of the alternating current contactor to be de-electrified to enable the power module to be de-electrified to stop working when the charging pile is in a standby state. According to the control circuit, the alternating current contactor and the information transfer and control unit are additionally arranged on the old charging pile with high standby power consumption originally, the power module can be powered off when the charging pile is in a standby state, and the aim of reducing the standby power consumption of the old charging pile is achieved.
本发明提供了一种用于降低老旧充电桩待机功耗的控制电路和控制方法,属于电动汽车充电桩领域。该控制电路包括交流接触器和信息中转与控制单元,交流接触器的常开触点用于串联在电网与老旧充电桩的功率模块输入端之间,信息中转与控制单元用于从老旧充电桩主控制器向平台交互终端发送的信息中获取充电桩状态,并在充电桩处于充电状态时控制交流接触器的线圈得电使功率模块得电;在充电桩处于待机状态时控制交流接触器的线圈失电使功率模块失电,功率模块停止工作。该控制电路通过在原本待机功耗很高的老旧充电桩上增加一个交流接触器和一个信息中转与控制单元,能在充电桩处于待机状态时给功率模块断电,达到降低老旧充电桩待机功耗的目的。
