A vehicle power supply apparatus includes first and second power supply devices, an electrical conduction path, an accumulator, an electric device, and a power supply controller. In switching to a state with electric power supplied from the second power supply device to the electric device, the power supply controller determines whether a discharge state of the accumulator is normal, with a target voltage of the second power supply device lower than an inferior voltage, and with a target voltage of the first power supply device between the inferior voltage and a superior voltage. After determining that the discharge state of the accumulator is normal, the power supply controller allows the target voltage of the first power supply device to be lower than the inferior voltage, and allows the target voltage of the second power supply device to be higher than the superior voltage.
