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;
an auxiliary power supplier configured to supply 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 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.

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.
