    摘要: A power control apparatus includes: a first power supply device that supplies main power, a second power supply device that supplies auxiliary power, a power divider that divides the main power input from the first power supplier, a first controller connected to a first output terminal of the power divider to control power supply to a first in-vehicle load by connecting or disconnecting the main power and the auxiliary power, and a second controller connected to a second output terminal of the power divider to control power supply to a second in-vehicle load using the main power. The first controller and the second controller diagnose a power failure in cooperation with each other and supply redundancy power using the main power or the auxiliary power based on a power failure diagnosis result.
