An ECU (75) controls drive signals (D1, D2) output to relays (50, 52). A current sensor (55) detects current flowing between the relay (50) and a power supply port (40). A connection circuit (60) is configured to electrically connect a first section (L12) with a second section (L21) when one of the drive signals (D1, D2) is activated by the ECU (75). The first section (L12) is between the current sensor (55) and the power supply port (40) in a power line (L1). The second section (L21) is between the relay (52) and the power supply port (40) in a power line (L2).
