A vehicle power supply apparatus includes first and second power supply systems, an electrical conduction path, first and second switches, and an abnormality determination unit. The first power supply system includes a first electrical energy accumulator and an electric load. The second power supply system includes a generator and a second electrical energy accumulator. The first switch is provided on the electrical conduction path between the first and second power supply systems. The second switch is provided in the second power supply system. The abnormality determination unit determines whether or not the generator is in an abnormal state, on the basis of a current of the first or second electrical energy accumulator, with the first switch or the second switch, or both turned on, and with a power generation command outputted to the generator.
