Abstract
To prevent damage of a vehicle or a cord set used to charge a plug-in electric vehicle when the vehicle is driven away while the cord set is attached, an interlock can be provided to disable the vehicle. Such interlock may be based on a protective door over the charging receptacle being open or detection that a cord set is plugged in. However, in the event that the vehicle is in an activated state, the interlock is prevented from disabling the vehicle according to an embodiment of the disclosure. That is, undesirable disabling of the vehicle is prevented when either there is no indication of a cord set being coupled to the vehicle or the vehicle is in an activated state.
