Abstract
Electric vehicles and plug-in hybrid electric vehicle derive all, or at least some, of their power from the electrical grid. The vehicle is provided with a receptacle into which a 110 Volt AC power cord can be plugged. According to the present disclosure, coupling of the external power supply and/or charging are prevented when the vehicle is not in a parked condition. The parked condition is based on the application of a vehicle parking brake and/or a gear shift selector being in a parked position. If a parked condition is not detected, one of the following measures is taken: a relay in the battery charger on board the vehicle is opened thereby disallowing charging; an access door to the receptacle is locked by an access door solenoid; and a plug ejector prevents insertion of a plug into the receptacle.
