An AC-DC converter converts an alternating-current voltage, supplied from an external power supply, to a direct-current voltage higher than a peak voltage of the alternating-current voltage, and outputs the direct-current voltage to a first power supply line. In a normal control mode, a DC-DC converter steps down a voltage of the power supply line through on/off control over a switching element to charge a main battery. On the other hand, in an upper arm ON control mode, the DC-DC converter charge the main battery while the switching element is kept in an on state. On the basis of a state of external charging, a control device applies the upper arm ON control mode when a condition that upper arm ON control is applicable is satisfied, and applies the normal control mode when the condition is not satisfied.
