The invention discloses an electric vehicle charging pile with low power consumption, a magnetic latching relay is used for replacing a conventional relay, the magnetic latching relay does not need to be supplied with power all the time, on-off of contacts of the magnetic latching relay can be controlled by means of pulses, and electric energy is effectively saved; according to the invention, a low-power-consumption state is entered in idle time, an unnecessary module power supply can be cut off and a main control module enters a low-power-consumption mode when the low-power-consumption state is entered, and when a human body proximity sensor, an IC card reader or a key has a signal, the main control module is triggered and awakened to exit the low-power-consumption mode through external interruption, and other modules are controlled to enter a normal working state.

    本发明公开了一种低功耗的电动车充电桩,使用磁保持继电器代替常规继电器,磁保持继电器无需一直供电,依靠脉冲可控制其触点通断,有效的节省电能;本发明在空闲时会进入低功耗状态,低功耗状态时,能断开不必要的模块电源,主控模块进入低功耗模式,当人体接近传感器、IC卡读卡器或按键有信号,通过外部中断触发唤醒主控模块退出低功耗模式,并控制其他模块进入正常工作状态。
