Abstract
A circuit measures temperature in a charging handleof an electric vehicle charging station (EVSE). A temperature sensor is connected between a control pilot lineand ground line G in the charging handle of the EVSE. The control pilot line transmits a square wave signal CP having positive and negative portions, to an electric vehicle, according to the SAE J1772 standard. A temperature monitorin the EVSE, coupled to a pilot signal measurement circuitin the EVSE, measures the negative portions of the square wave signal resulting from the temperature sensor conducting current in response to changes in temperature in the handle. Temperature measurement of the charging handle is achieved without significant added cost or complexity, by reusing existing components in the EVSE, with little or no modification required to EVSE electronics, and minimal modification of the handle.
