A power conversion device for charging first and second batteries is provided. The power conversion device includes an input unit converting a commercial alternating current (AC) power supplied from the outside into a direct current (DC) power to output the converted DC power, a first power conversion unit converting the DC power converted through the input unit into an AC power to output the converted AC power, a second power conversion unit converting the AC power converted through the first power conversion unit into a DC power to charge the first battery in a first operation mode, the second power conversion unit converting the DC power outputted through the first battery into an AC power in a second operation mode, a third power conversion unit converting the AC power converted through the second power conversion unit into a DC power to charge the second battery in the second operation mode, and a switching unit connecting the first power conversion unit to the second power conversion unit in the first operation mode according to a control signal supplied from the outside, the switching unit connecting the second power conversion unit to the third power conversion unit in the second operation mode according to the control signal supplied from the outside.
