A vehicle includes a power storage device, a motor generator, a converter for stepping up an output voltage from the power storage device, an inverter for driving the motor generator, and an ECU. The inverter includes switching elements. The switching elements have a characteristic that the withstand voltage of the switching elements decreases as the temperature of the inverter decreases. The ECU sets the stepped-up voltage, based on a temperature characteristic of the power storage device and a temperature characteristic of the inverter, so that the stepped-up voltage is increased within a range in which the stepped-up voltage does not exceed the withstand voltage. In this way, at low temperatures, deterioration of the power performance can be suppressed while the switching elements are protected.
