Beschreibung
Zusammenfassung:	The invention provides a vehicle power supply apparatus iand a vehicle power regeneration system capable of increasing the fuel consumption rate of vehicles bu employing regeneration electric power and providing the electric power to loads during re-starting of an engine. When a vehicle is travelling, and a generator (13) does not generate electricity, if a voltage of an electricity storage unit (11) is greater than a predetermined value, a switching element (3) is turned on, and the driving of a DC-DC converter (2) is controlled such that the electricity storage unit (11) discharges electricity to supply electric power of the electricity storage unit (11) to loads (14-16), and even if the voltage of the electricity storage unit (11) decreases to the predetermined value, as long as the vehicle speed is greater than or equal to a threshold value, the switching element (3) is turned on, and the driving of the DC-DC converter (2) is controlled such that the electricity storage unit (11) discharges electricity to supply the electric power of the electricity storage unit (11) to the loads (14-16).
