Abstract

An AC power adapter for a plug-in electric vehicle has a connector for reception in a charging port of the plug-in electric vehicle, at least one AC outlet coupled to the connector and command generation circuitry coupled to the connector for generating a command that causes the plug-in electric vehicle to put itself into a power feedback mode wherein AC power generated by the plug-in electric vehicle and provided to its charging port is coupled through the connector to the AC outlet.

Claims

1. An AC power adapter for a plug-in electric vehicle, comprising:

a connector for reception in a charging port of the plug-in electric vehicle;

at least one AC outlet coupled to the connector; and

command generation circuitry coupled to the connector for generating a command that causes the plug-in electric vehicle to put itself into a power feedback mode wherein AC power generated by the plug-in electric vehicle and provided to its charging port is coupled through the connector to the AC outlet.

2. The AC power adapter of claim 1 wherein the AC adapter includes an AC power adapter pilot signal generator and an AC power adapter proximity circuit and the command generation circuitry includes the AC power adapter pilot signal generator that generates a pilot signal with signaling protocol for the command.

4. The AC power adapter of claim 2 including a circuit protection device coupled between the AC outlet and the connector.

5. The AC power adapter of claim 4 wherein the J1772 connector houses the AC power adapter pilot signal generator and the AC power adapter proximity circuit.

6. The AC power adapter of claim 5 including a power strip having the at least one AC outlet, the power strip coupled to the housing by a power cord.

7. The AC power adapter of claim 5 wherein the power strip includes a plurality of the AC outlets.

3. The AC power adapter of claim 3 wherein the command generation circuitry also includes the AC power adapter proximity circuit.
