Zusammenfassung:	A vehicle power supply apparatus includes: a switching element; a DC-DC converter; and a control unit. When a vehicle is travelling, and a generator does not generate electricity, if a voltage of an electricity storage unit is greater than a predetermined value, the control unit turns on the switching element, and controls driving of the DC-DC converter such that the electricity storage unit discharges electricity to supply electric power of the electricity storage unit to loads, and even if the voltage of the electricity storage unit decreases to the predetermined value, as long as the vehicle speed is greater than or equal to a threshold value, the control unit turns on the switching element, and controls the driving of the DC-DC converter such that the electricity storage unit discharges electricity to supply the electric power of the electricity storage unit to the loads.
