1. A charging station for a plug-in electric vehicle (PEV), comprising:
- an inverter including an inverter DC input operative to receive DC input power and an inverter AC output operative to provide AC output power to an AC power grid, the inverter being operable to convert the DC input power to the AC output power;
a DC charger, including;
a charger DC input operative to receive power from at least one DC power source,a DC vehicle battery interface coupleable to a PEV DC battery connection, and,a DC charger output coupled to the inverter DC input to provide DC output power to the inverter,the DC charger being operative in a first mode to provide power from the charger DC input to the vehicle battery interface and in a second mode to provide power from the vehicle battery interface to the charger DC output; and
,a controller operatively coupled with the DC charger to selectively switch the DC charger from the first mode to the second mode.

11. A method for operating a plug-in electric vehicle (PEV) charging system, comprising:
-
selectively operating a DC charger in a first mode, including; directing DC current from a DC power source through a DC charger input to the DC charger, and directing DC current from the DC charger through a DC vehicle battery interface to a vehicle battery; and
,selectively operating the DC charger in a second mode, including; directing DC current from the vehicle battery through the DC vehicle battery interface and through a DC charger to an inverter DC input, converting the DC current to AC current using an inverter, and directing AC current from the inverter through an inverter AC output to an AC power grid. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
