Abstract
A system for connecting an electric vehicle to a high voltage power source is disclosed. The system including an electric vehicle supply equipment (EVSE) having an electrical plug compatible with a high voltage power outlet, the plug connected to a power cord. The power cord is connected to a housing containing a number of electrical components configured to control the power flow to an electric vehicle to recharge the vehicle's batteries. The power cord extends from the housing and is connected to a standard electric vehicle connector compatible with battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV). The EVSE further includes safety measures, such as a relay that controls the flow of power to the vehicle connector, a ground fault interrupter, and a circuit tester to protect users from high voltage electric shocks.
