A charging system for an electric vehicle includes a charger connector configured to be connected to a charging port on the electric vehicle and including a housing, a first conductor passing through the housing, a second conductor passing through the housing, and a current sensor, the current sensor is configured to sense a current flowing through at least one of the first conductor and the second conductor to a battery system of the electric vehicle. The charger-side controller includes an arc fault detection module configured to selectively identify a DC arc fault in response to the measured current sensed by the current sensor, and stop charging the electric vehicle in response to detecting the DC arc fault.
一种用于电动车辆的充电系统包括充电器连接器,充电器连接器被配置成连接到电动车辆上的充电端口,并且包括壳体、穿过壳体的第一导体、穿过壳体的第二导体、以及电流传感器,电流传感器被配置成感测流过第一导体和第二导体中的至少一个到电动车辆的电池系统的电流。充电器侧控制器包括电弧故障检测模块,该电弧故障检测模块被配置成响应于由电流传感器感测的测量电流选择性地识别直流电弧故障,并响应于检测到直流电弧故障而停止对电动车辆充电。
