PROBLEM TO BE SOLVED: To prevent a travellable distance from being shortened when abnormality occurs in insulation resistance of an electric system.SOLUTION: A charging device 450 is connected to a second battery B2 and charges the second battery B2 using electric power received from a power supply outside a vehicle. A switching device 500 switches between application and interruption of direct current voltage to an inverter 8. A control device 100, when degradation of insulation resistance of a drive portion of an electric system is detected, controls the switching device 500 so that the direct current voltage is applied to the inverter 8, and stops operation of the inverter 8 and makes the charging device 450 charge the second battery B2.
