A vehicle power supply apparatus includes first and second device batteries, a power supply line, and a current path. The power supply line includes first, second, and third segments. The first segment is coupled between a first end of the power supply line and a first diode. The second segment is coupled between the first diode and a first switch. The third segment is coupled between the first switch and a second end of the power supply line. The current path is routed from the third segment to the first segment through a second diode, to bypass the second segment. An electric device of a vehicle is coupled to the first segment. The second device battery is coupled to the second segment. The first device battery is coupled to the third segment through a second switch.
