Abstract

A power charging and selling device includes first and second connection units configured to be connected to an electric vehicle and at least one power supplier server, respectively; a control unit for receiving a unique identifier and battery information of the electric vehicle through the first connection unit and for receiving power-trading charge information provided from each power supplier server through the second connection unit; and a guide unit for advertising the received power-trading charge information and for enabling selection of a corresponding power supplier. Through the first connection unit, the control unit may charge the electric vehicle with the power of a selected power supplier or sell the power stored in the electric vehicle to a selected power supplier. The power charging/selling device receives charge information from power suppliers, and a user selects the charging/selling scheme accordingly, even if the power source of the electric vehicle is turned off.
