    摘要： A breakdown of a load caused by abnormality of a high-voltage battery is prevented in starting supply of power from the high-voltage battery (111) to each load. In starting the supply of the power from the high-voltage battery (111) to a DC-DC converter (112) and a high-voltage load (102), a high-voltage battery control ECU (114) detects the abnormality of the high-voltage battery in a state in which relays RY1a and RY1b are opened while relays RY2a and RY2b are closed. The high-voltage battery control ECU (114) closes the relays RY1a and RY1b and opens the relays RY2a and RY2b when the abnormality is not detected. The high-voltage battery control ECU continuously opens the relays RY1a and RY1 b when the abnormality is detected. For example, the invention can be applied to a power-supply control system of an electric-powered vehicle.
