The invention relates to a low-impedance short-circuit detection circuit for a charging interface of an alternating-current charging pile and the alternating-current charging pile, and belongs to the field of charging fault detection. Comprising a detection loop and a signal processing loop, a first divider resistor and a control switch are connected in series in the detection loop, and the control switch is used for connecting a null line and a live line of the AC output port in the detection loop in series when the AC output port is not charged; the signal processing loop is connected with a voltage detection point in the detection loop and is used for outputting a signal for judging whether the zero line and the live wire are short-circuited or not according to potential change of the voltage detection point caused by impedance between the zero line and the live wire, so that short-circuit detection between the zero line and the live wire of the charging pile can be still realized when equipment is idle, and the safety is higher; and the accuracy is better.

    本发明涉及一种交流充电桩充电接口低阻抗短路检测电路及交流充电桩,属于充电故障检测领域。包括一端连接电源一端接地的检测回路和信号处理回路;所述检测回路中串联有第一分压电阻和控制开关,所述控制开关用于在未充电时将交流输出端口的零线和火线之间串联进检测回路;信号处理回路与检测回路中的电压检测点连接,用于根据零线和火线之间的阻抗导致的电压检测点的电势的改变来输出用于判断零线和火线之间是否短路的信号,使设备在空闲时依旧能实现充电桩零线火线间的短路检测,安全性更高,准确性更好。
