Abstract: When power storage units (10) and (20) are both in a normal condition, system relays (SMR1) and (SMR2) are maintained in an ON state. A converter (18) performs a voltage conversion operation in accordance with a voltage control mode (boost), and a converter (28) performs a boost operation in accordance with an electric power control mode. If some kind of fault condition occurs in the power storage unit (10) and the system relay (SMR1) is driven to an OFF state, the converters (18) and (28) stop the voltage conversion operation and maintain an electrically conducting state between the power storage units (10) and (20) and a main positive bus (MPL), a main negative bus (MNL).

Abstract: A power supply system for driving a vehicle includes a battery (B), a boost converter (12) boosting the voltage of the battery (B), a capacitor (40) to which the voltage boosted by the boost converter (12) is applied across the electrodes, system main relays (C-SMRP, C-SMRG) provided between the capacitor (40) and the output of the boost converter (12) for connection and disconnection between the capacitor (40) and the boost converter (12), and a control device (30) controlling the boost converter (12) and the system main relays (C-SMRP, C-SMRG). The control device (30), after giving an instruction for disconnection to the system main relays (C-SMRP, C-SMRG), causes the boost converter (12) to change the voltage of the output to determine whether the system main relays (C-SMRP, C-SMRG) are normally disconnected.
