Abstract:
1. An in-vehicle power supply apparatus that provides power supply from a secondary battery installed in a vehicle to in-vehicle devices, the in-vehicle devices being classified based on attributes of the in-vehicle devices, the in-vehicle power supply apparatus comprising: a voltage compensating unit that compensates for a power supply voltage supplied to a first set of at least one in-vehicle device that is selected from the in-vehicle devices based on the attributes by increasing the power supply voltage in a case where a voltage supplied to the in-vehicle devices has become less than or equal to a first predetermined value; and an uninterruptible power supply unit that supplies electric power of a further secondary battery different from the secondary battery to a second set of at least one in-vehicle device that is selected from the in-vehicle devices based on the attributes in a case where a voltage supplied to the in-vehicle devices has become less than or equal to a second predetermined value that is smaller than the first predetermined value, the second set of at least one in-vehicle device being different from the first set of at least one in-vehicle device.
