Abstract
A vehicle power supply apparatus includes first and second power supply systems, first and second switches, and a fail-safe controller. The second power supply system includes a generator motor coupled to an engine, and a second electrical energy accumulator able to be coupled to the generator motor. The fail-safe controller inhibits a powering state of the generator motor on the condition that the second switch is in a malfunctioning state in which the second switch is rendered inoperative in a second turn-on state. The second turn-on state includes coupling the generator motor and the second electrical energy accumulator to each other.
