Claim 7:
8. A power supply system for a mobile object, comprising:
a normal power supply that is configured to supply electric power to a normal load;
a normal current path that is connected to the normal power supply;
a redundant power supply that is a power supply different from the normal power supply, and configured to supply electric power to a redundant load, the redundant load including a first redundant load and a second redundant load;
a redundant current path that is connected to the redundant power supply;
a first current path that is provided between the normal current path and the redundant current path, and connected to the first redundant load;
a second current path that is disposed in parallel with the first current path, between the normal current path and the redundant current path, and connected to the second redundant load;
a path switch that includes a first normal switch, and a second normal switch, the first normal switch configured to switch a state of connection between the normal current path and the first current path, the second normal switch configured to switch a state of connection between the normal current path and the second current path; and
a controller that is configured to control to turn on and off the path switch, wherein
the normal power supply is connected to the normal load, and is connectable to at least one of the first redundant load and the second redundant load,
the normal power supply includes an auxiliary battery storing electric power to be supplied to the normal load, and
the redundant power supply includes a redundant battery having a storage capacity smaller than that of the auxiliary battery.
