Abstract
In the case the gearshift position is the parking position at the state that the master battery is connected via the master side step-up circuit to the motor side and either of the two slave batteries is connected via the slave side step-up circuit to the motor side, the drive of both of the master side step-up circuit and the slave side step-up circuit is stopped. After then, in the case that the accumulated charge ratio difference obtained by subtracting the accumulated charge ratio of the master battery from the accumulated charge ratio of the slave battery connected to the motor side is less than the threshold value, the drive stop of both of the master side step-up circuit and the slave side step-up circuit is continued.
