Beschreibung
Zusammenfassung:	A vehicle power supply apparatus includes first and second device batteries, first and second power supply lines, a current path, first and second switches, and a second diode. The current path is coupled between the first and second power supply lines through a first diode. The first diode is provided on the current path and directed to make a current flow toward the second power supply line. The first switch is interposed between the first device battery and the first power supply line. The second diode and the second switch are interposed between the second device battery and the second power supply line. The second diode is directed to make a current flow toward the second power supply line, and the second switch is coupled in parallel to the second diode.
