More Information
Summary:A temperature sensor 120 automatically shuts down charging operations in response to a temperature increase in a charging handle 150 of an electric vehicle charging station 100. The temperature sensor is connected between a ground conductor and a high voltage conductor L1 in the charging handle. The charging handle includes a return conductor L2/N. The temperature sensor includes a thermistor R1-NTC that changes its resistance in response to an increase in temperature in the charging handle. A portion of current in the high voltage conductor is diverted to the ground conductor, instead of the return conductor, in response to the thermistor sensing a temperature increase, thereby causing a ground fault detector 160 to trip in the charging station.
