Abstract
A vehicle power supply apparatus includes a generator, an electrical energy accumulator, a throttle valve, a power generation controller, a throttle plate position upper limit setting unit, and a throttle valve controller. The generator is coupled to an engine of a vehicle. The electrical energy accumulator is able to be coupled to the generator. The throttle valve is provided in an intake system of the engine. The power generation controller allows the generator to perform regenerative power generation on decelerated travel of the vehicle. The throttle plate position upper limit setting unit sets an upper limit of a throttle plate position of the throttle valve on the basis of a state of the electrical energy accumulator. The throttle valve controller controls the throttle plate position within a range downward from the upper limit, during the regenerative power generation by the generator.
