A first opening/closing device (SMRB1, SMRG1, SMRP, R1) is configured to include a precharging relay (SMRP) and a limiting resistor (R1) connected in series between a first power storage unit (BAT1) and a first pair of power lines (PL1, NL1). A second opening/closing device (SMRB2, SMRG2) is configured not to include the precharging relay (SMRP) and the limiting resistor (R1). When precharging a capacitor C1 using a second power storage unit (BAT2), a control device controls opening/closing of first to fourth opening/closing devices (SMRB1, SMRG1, SMRP, R1, SMRB2, SMRG2, CHRB1, CHRG1, CHRB2, CHRG2) so as to form an electric conduction path extending between the second power storage unit (BAT2) and the capacitor (C1) via the precharging relay (SMRP) and the limiting resistor (R1). |
