Kind Code:
A1
Abstract:
The present invention relates to an electric vehicle charging system. A charging system according to any one preferred embodiment of the present invention comprises: a battery for performing both charging and discharging; a boost unit for boosting the output voltage of the battery to a preset voltage; a charging terminal for receiving power from the outside of the charging system or supplying power to the outside; a switch for directly connecting the battery and the charging terminal or connecting the boost unit and the charging terminal, according to a charging or discharging mode of the charging system; and a control unit for controlling the switch according to the charging or discharging mode of the charging system. In addition, when the charging system is in the charging mode, the control unit controls the switch such that the charging terminal and the battery are directly connected. In this case, the battery is charged by the power supplied from the outside. When the charging system is in the discharging mode, the switch is controlled such that an output of the battery is connected to the charging terminal through the boost unit. In this case, battery power is supplied to the outside.
