Disclosed is a charging apparatus to supply a power to a battery of an electric vehicle. The charging apparatus includes a bidirectional power conversion unit including three pairs of switching device groups and having one end connected to a power system and an opposite end; an energy storage unit connected to the opposite end of the bidirectional power conversion unit to store the DC power output through the opposite end of the bidirectional power conversion unit; a multi-DC power output unit to output the DC power to an outside in the first inverse operation mode; and a charging control unit to detect a charging condition of the charging apparatus. The switching device groups serve as buck-converters, respectively, in the first inverse operation mode to convert the DC power into another DC power having a level different from a level of the DC power.
