When the master battery is connected to the motor side via a master side step-up circuit while one of two slave batteries is also connected to the motor side via a slave side step-up circuit, and when the shift position is in the park position (S310), driving of the master side step-up circuit and the slave side step-up circuit is stopped (S340, S350, S380). After this, while driving of the master side step-up circuit and the slave side step-up circuit is stopped and when the charge ratio difference ?SOC, obtained by subtracting the master battery charge ratio from the charge ratio of the slave battery connected to the motor side, is no more than a threshold value ?Sref1 (S360, S370), drive stoppage of the master side step-up circuit and the slave side step-up circuit is continued (S380). |
