PURPOSE: A portable device for providing a billing and electric charging service for discharged electric vehicles is provided to perform an easy control of the charging service by using a built-in circuit or a mobile terminal for electric vehicles. CONSTITUTION: A first charge cable(240) comprises a power transmission cable; a flexible cable composed of a communication line, a control pilot signal wire and a wakeup signal line; and a connector. A second charge cable(250) comprises a power transmission cable; a flexible cable composed of a communications line, a control pilot signal wire and a wakeup signal line; and a connector. A power control unit(220) measures the electric energy supplied to a first vehicle from a second vehicle. A communications control unit(230) is connected to the communication line, the control pilot signal wire and the wakeup signal line of the first charge cable, and the communication line, the control pilot signal wire and the wakeup signal line of the second charge cable. A charge administration unit(210) performs the control through the communications control unit based on the control pilot signal wire of the first vehicle and the second vehicle.
