Abstract
An electric vehicle supply equipment (EVSE) assembly for an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), often referred to as, optionally having one of at least two interchangeable power supply cords with plugs that conform to different technical standards, such as National Electrical Manufacturers Association (NEMA) 5-15P or 6-20P. The interchangeable power supply cord plugs each include a thermistor adapted to monitor plug temperatures. The electronic module is configured to disable charging until a proper resistance of the thermistor in the plug is detected. The electronic module is also configured to automatically switch between 120 volt and 240 volt operation based on which of the interchangeable power supply cords is connected to the electronic module.
