A vehicle power supply apparatus includes a motor generator, a first electricity storage, a second electricity storage, a first switch, a second switch, a switch controller, and an electricity storage determiner. The first and second electricity storages are able to be coupled to the motor generator that is coupled to an engine. The first switch and the second switch each switch from electric conduction between the motor generator and corresponding one of the first and second electricity storages to cutoff between the motor generator and corresponding one of the first and second electricity storages and vice versa. The switch controller controls the first switch and the second switch. The electricity storage determiner determines an abnormality of the first electricity storage. The switch controller controls each of the first switch and the second switch into an electrically-conductive state when the first electricity storage is determined as being in an abnormal state.
