Abstract: A power supply device includes a main power supply, a sub-power supply, a main power supply path, a sub-power supply path, a power supply selector switch, and a load selector switch group. The main power supply path is connected to the main power supply. The sub-power supply path is different from the main power supply path and is connected to the sub-power supply. The load selector switch group is disposed between the main power supply path and the sub-power supply path, and the load unit, and performs switching so as to connect one of the main power supply path and the sub-power supply path to the load unit and to disconnect the other from the load unit, according to switching of the power supply selector switch.

Abstract: A vehicle power supply system includes a power supply path, and an ECU detaching a fault occurrence portion occurring in a part of the power supply path from the power supply path based on a set value lower than a lowest operation voltage of a load and a voltage related to the power supply path. The set value is set within a normal range of the voltage related to the power supply path. The power supply path includes a plurality of electrical connection units connected to the load and a plurality of connection wirings connecting each of the electrical connection units in a loop shape. In a case that a part of voltages related to each of the connection wirings is equal to or less than the set value, the control unit supplies power to the load via another part of the voltages related to each of the connection wirings.
