Method and Apparatus for Preventing Simultaneous Charging and Fueling of a Plug-In Hybrid Electric Vehicle

摘要

Simultaneous fuelling and electrical charging of a plug-in electric hybrid vehicle (PHEV) is inhibited by detecting pre-charging electrical continuity between an on-board charger of the vehicle and a charging plug engaging the charger, and impeding opening of a door controlling access to a fueling port if the pre-charging electrical continuity exist. Simultaneous fuelling and electrical charging of a PHEV may further be inhibited by detecting whether a fuel door of the vehicle is in a fueling-permitting condition and, if the fuel door is in the fueling-permitting condition, preventing an on-board charger engaged with a charging plug from receiving charging current from the charging plug.

主权项

1. Apparatus for a vehicle comprising:
an on-board charger connectable with a charging plug to receive charging current therefrom; a door controlling access to a fueling port; and a control module operative to prevent the on-board charger from receiving charging current in response to the door being in a fueling-permitting condition when the charger and the plug are in pre-charging electrical connection.
