  • Battery powered vehicle with immobilizing charger plug
    Patent number: 9296306
    Abstract: A battery powered vehicle may include a battery power source, an electric drive motor, a charging receptacle, and a drive controller. The electric drive motor may be powered by the battery power source. The electric drive motor may be operably coupled to a wheel of the battery powered vehicle to provide drive power for the battery powered 5 vehicle. The charging receptacle may be configured to enable charging of the battery power source via a battery charging assembly connectable to the charging receptacle. The charging receptacle may include circuitry forming a detection loop closed responsive to operable coupling of the charging receptacle with a charger plug of the battery charging assembly. The closing of the detection loop may generate an indication that the charging 10 receptacle is operably coupled to the charger plug.
