System monitoring power connector and cable health

A method of protecting an electric vehicle (EV) charger connector 200 from excessive heat includes monitoring the internal temperature of an electrical connector (block 1500), the electrical connector 200 having pilot and pilot return signal lines (235, 240), reducing a voltage between the pilot and pilot return signal lines (block 1515) in response to the internal temperature exceeding a first threshold (block 1505), and reducing charging current provided through the electrical connector in response to the change in voltage (block 1520) so that the internal temperature exceeding the first threshold will result in a reduction of charging current through the connector. 种保护电动车辆(EV)充电器连接器200免受过多的热的方法包括：监测电连接器的内部温度(块1500)，电连接器200具有导引线和导引返回信号线(235、240)；响应于内部温度超过第阈值(块1505)而降低在导引线和导引返回信号线之间的电压(块1515)，以及响应于电压的变化而减小通过电连接器提供的充电电流(块1520)，使得内部温度超过第阈值将导致通过连接器的充电电流的减小。
