A power supply system is for supplying electric power to a load via a power supply line. The power supply system includes power storage device, a voltage converter, a switchgear, an abnormality signal output device and an electronic control unit. The abnormality signal output device is configured to output an abnormality signal when an abnormality of one switching element of the voltage converter is detected. The electronic control unit is configured to a) control switching elements of the voltage converter and the switchgear; b) switch the switchgear from the connected state to the disconnected state when receiving the abnormality signal from the abnormality signal output device; c) output an ON signal to close the one switching element whose abnormality is detected; and d) identify that the abnormality is short circuit failure when receiving the abnormality signal from the abnormality signal output device again after execution of b) and c).
