Battery powered vehicle with immobilizing charger plug
First Claim
1. A battery powered vehicle comprising:
- a battery power source;
an electric drive motor powered by the battery power source, the electric drive motor being operably coupled to a wheel of the battery powered vehicle to provide drive power for the battery powered vehicle;
a charging receptacle configured to enable charging of the battery power source via a battery charging assembly connectable to the charging receptacle, the charging receptacle comprising circuitry forming a detection loop closed responsive to operable coupling of the charging receptacle with detection loop completion circuitry provided in a charger plug of the battery charging assembly, closing of the detection loop generating an indication that the charging receptacle is operably coupled to the charger plug; and
a drive controller comprising processing circuitry configured to implement a mobility restriction at least with respect to operation of the electric drive motor responsive to the indication,wherein the detection loop completion circuitry is configured to complete a signal path from the drive controller to the charger plug and back to the drive controller, that implements the mobility restriction and enables operation of at least one auxiliary function.

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. The drive controller may include processing circuitry configured to implement a mobility restriction at least with respect to operation of the electric drive motor responsive to the indication.
