PROBLEM TO BE SOLVED: To effectively warm a battery while suppressing an increase of a noise during steady travel.SOLUTION: A hybrid vehicle 100 is equipped with: a battery 10; a boosting converter 20; inverters 30, 40; motor generators 50, 60 and a battery temperature sensor 89; a battery current sensor 83; a high voltage sensor 85; and a control part 90. The control part 90 is equipped with: a boosting intermittent operation program 94 which stops the boosting converter 20 when an absolute value of a battery current IB is within ±Iin the case that a temperature of the battery 10 is equal to or higher than a predetermined temperature T, and re-starts the boosting converter 20 when a real boosting voltage VHr is not within a range of VHand VH; and a threshold changeover program 95 which changes a threshold range into ±Iwider than ±Iand changes the range of thresholds VHand VHinto a wider range of thresholds VHand VHwhen a battery temperature TB is less than the predetermined temperature T. |
