PROBLEM TO BE SOLVED: To allow charging to a low voltage battery from a high voltage battery in polarizing state where charging/discharging is prohibited, relating to a charging mode for charging from an external power source of a plug-in hybrid automobile.SOLUTION: When a high voltage battery 16 is in polarizing state, charging/discharging from the battery 16 is prohibited in principle. When an accumulated amount of a low voltage battery 24 comes to be a predetermined value or less, even if charging/discharging with the high voltage battery 16 is prohibited, the high voltage battery 16 is discharged and its power is charged to the low voltage battery 24. |
