Claim 0:
1. A power control device positioned between a power distribution device connected to an output terminal of a first power supply and a second power supply, the power control device comprising:
a power control switch configured to selectively connect or separate a main power output from the first power supply and an auxiliary power output from the second power supply; and
a processor configured to determine a possibility of an open-circuit fault of a vehicle power source based on a current flowing through the power control switch and to determine whether it is possible to drive an electric load with an output power of the second power supply alone and to determine an open-circuit position based on an output of the first power supply upon determining that there is the possibility of the open-circuit fault,
wherein the open-circuit position is between the power distribution device and the power control device or between the first power supply and the power distribution device.
