Abstract

The present invention provides an apparatus for charging an electric powered vehicle. The apparatus includes a vehicle charging connector; an electrical power storage unit that is connected to the vehicle charging connector, receives electricity from the outside through a powerline, and stores the electricity; and a PAN (powerline area network) modem that is connected to the vehicle charging connector, connects the powerline with the vehicle information terminal, and transmits a data signal. Accordingly, it is possible to overcome potential noise of a powerline, high load interference, data signal distortion, and the like that occur when a data signal is transmitted while charging a vehicle by a PLC technique in the related art, and to allow a user to effectively and reliably transmit a data signal to a vehicle information terminal through a powerline while charging a vehicle.

Claims
