The present invention relates to a control system to control charging of a charger to charge a first battery used to drive a vehicle and mounted on an electric vehicle, by receiving power from an electric vehicle supply equipment. An integrated onboard battery charger (OBC) mounted on an electric vehicle includes: a charge unit to charge the first battery used to drive a vehicle and mounted on an electric vehicle, by receiving power through a connector, which connects the power source of the electric vehicle to the electric vehicle; a charge control unit to control a charging operation of the charge unit by receiving a generated control pilot signal from a control electronic device; and an OBC connection circuit unit to provide the received signal to the charge control unit by receiving a generated control pilot signal from a power source according to a switching signal of the charge control unit. The charge control unit controls the power source to supply power to the onboard charger from a power supply line directly connected to a second battery for a vehicle when connection by the connector to the power source is detected.
