During warm-up operation of the auxiliary battery (19), the output voltage of the DC-DC converter (20) is set to a second predetermined voltage (e.g. 14.3 V) lower than the first predetermined voltage. While the vehicle (10) is traveling, the output voltage of the DC-DC converter (20) is set to a third predetermined voltage (e.g. 14.2 V) lower than the second predetermined voltage.
