Abstract: A power supply system includes: an inter-load switch including a first switch and a second switch connected in series, a voltage generation unit, an electric storage device connected between the first switch and the second switch, a first state control unit configured to select a first state in which power is supplied from at least one of the voltage generation unit or the electric storage device to a first load and a second load, and a second state control unit configured to, when determining that a failure has occurred, select a second state in which power is supplied from the electric storage device to a load on a side of a no-failure-occurrence system in which no failure has occurred, by turning off a switch on a side of a failure-occurrence system in which a failure has occurred and turning on a switch on a side of the no-failure-occurrence system.

Abstract: A power supply system includes a first power output portion, a second power output portion, and a ring-form main pathway. A power supply system includes a first output pathway connecting the main pathway with the first power output portion, a second output pathway connecting the main pathway with the second power output portion, and a loading pathway connecting the main pathway with an electric load. The power supply system includes multiple main switches and a control unit. The main switch is configured to switch between a ring connection state and a non-ring connection state of the main pathway. The control unit controls the switching of the main switch. The control unit is configured to activate a non-ring connection mode that turns off one of the main switches and turns on the remainder of the main switches.

Abstract: A power supply system includes a first-battery, a battery unit including a second-battery, and a generator. The battery unit is connected to the generator and the first-battery via a conductor. The battery unit includes a connection-terminal connected to the conductor, an output-terminal connected to a load, a first-switch disposed on a wiring connecting the connection-terminal and the output-terminal, a branch line branching off from the wiring between the first-switch and the output-terminal and connected to the second-battery, a second-switch disposed on the branch line between the wiring and the second-battery, a first-voltage-detecting unit detecting voltage of the connection-terminal, and a switch control unit controlling the first and second-switches. The power supply system further includes a second-voltage-detecting unit detecting is electromotive force of the first-battery, and a fault-determining unit determining a fault of the conductor based on opening/closing states of the first and second-switches and results of the first and second-voltage-detecting units.
