A charger includes a conversion unit for converting external electric power from a charging port into DC, a conversion unit for converting the output of the preceding conversion unit into high-frequency AC, and a conversion unit for converting the electric power generated by transforming the output of the preceding conversion unit by an insulated transformer into DC to output the DC to a power storage device. The charger further includes a switch unit that enables the circuit configuration of the charger to switch between a single-stage charging circuit and a dual-stage charging circuit. The switch unit is controlled by a control signal from an ECU. The ECU controls the switch unit in accordance with the SOC of the power storage device and switches the circuit configuration of the charger to one of the single-stage charging circuit and the dual-stage charging circuit.
