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.
