PROBLEM TO BE SOLVED: To provide a power supply system the fuse of which can be checked while suppressing increase in the number of circuit elements and sensors.SOLUTION: A vehicle 1 includes a power supply unit 11, relays 16, 18, a voltage detection unit 26, a timer circuit 24, a switch circuit 32 and an ECU 30. The power supply unit 11 includes a power storage device 12 and a fuse 14 serially connected to the power storage device 12. The switch circuit 32 connects the voltage detection unit 26 to either of one terminal TA of the relay 16 connected to the side of the power supply unit 11 or the other terminal TB of the relay 16 connected to the side of a power supply terminal TP. The ECU 30 and the timer circuit 24 control the relay 16 and the switch circuit 32. Determination of fusion of the fuse 14 and determination of deposition of the relay 16 are executed on the basis of voltage detected by the voltage detection unit 26.SELECTED DRAWING: Figure 1 |
