SYSTEM FOR RESPOND TO A DEMAND RESPONSE, CONTROL CIRCUIT FOR ELECTRIC VEHICLES TO RESPOND TO A DEMAND RESPONSE AND METHOD FOR DRIVING THE SAME

The present disclosure relates to a system for respond to a demand response, a control circuit for electric vehicles, and a method for driving the same capable of efficiently responding to a demand response. The system includes an on board diagnostic configured to receive a demand response signal directly from a distributed energy resource management system and output a command signal according to the demand response signal from the distributed energy resource management system, a charging device configured to charge a battery of an electric vehicle, and a charge reference change circuit configured to modulate a pilot signal supplied from a charging equipment to the charging device according to a command signal from the on board diagnostic.
