Vehicle charger and method for controlling power thereof
First Claim
1. A vehicle charger receiving power from electric vehicle supply equipment to charge a battery mounted within a vehicle, comprising:
- a charging controller configured to operate a charging mode of the vehicle charger;
a main power supplier configured to supply main power to the charging controller, wherein the main power is battery power output from the battery;
an auxiliary power supplier configured to supply the battery power as auxiliary power in response to receiving a control pilot signal generated from the electric vehicle supply equipment; and
a power controller configured to detect the control pilot signal when an engine of the electric vehicle stalls and turn the main power supply and the auxiliary power supply on and off based on state information regarding the detected control pilot signal and a charging mode control signal output from the charging controller,wherein the auxillary power supplier supplies the battery power to the power controller in response to detecting the control pilot signal.

Abstract
A vehicle charger is provided that receives power from electric vehicle supply equipment to charge a battery mounted within an electric. The charger includes a charging controller that is configured to execute a charging mode of the vehicle charger and a main power supplier that is configured to supply main power to the charging controller. In addition, an auxiliary power supplier is configured to supply battery power as auxiliary power when receiving a control pilot signal generated from the electric vehicle supply equipment. A power controller is configured to detect the control pilot signal and turn the main power supply and the auxiliary power supply on and off based on state information regarding the detected control pilot signal and a charging mode control signal output from the charging controller.

13. A method for controlling power of a vehicle charger, comprising:
-
entering, by a power controller, a ready state when an auxiliary power supplier supplies battery power to the power controller in response to sensing a control pilot signal generated from electric vehicle supply equipment; receiving, by the power controller, a charging mode control signal and state information regarding a control pilot signal in the ready state; determining, by the power controller, a next state based on the charging mode control signal and the state information; and entering, by the power controller, the next state to output a power control signal based on the corresponding state, wherein the power controller detects the control pilot signal when an engine of the electric vehicle stalls. - View Dependent Claims (14, 15, 16, 17)
