A method of protecting an electric vehicle (EV) charger connector from excessive heat includes monitoring the internal temperature of an electrical connector, the electrical connector having pilot and pilot return signal lines, reducing a voltage between the pilot and pilot return signal lines in response to the internal temperature exceeding a first threshold, and reducing charging current provided through the electrical connector in response to the change in voltage so that the internal temperature exceeding the first threshold will result in a reduction of charging current through the connector.
