Abstract

An electric power supply device for a vehicle includes an electric storage device, a boost converter, and a controller. The boost converter boosts voltage of the electric storage device and supplies the boosted voltage to an electric load of the vehicle. The controller controls the boost converter in a continuous boost mode and an intermittent boost mode. The continuous boost mode is a mode in which the boost converter is in continuous operation. The intermittent boost mode is a mode in which the boost converter is in intermittent operation. The controller more restricts a charge/discharge demand of the electric storage device such that a charge/discharge demand of the electric storage device at a time when the boost converter is operated in the intermittent boost mode is more restrictive than a charge/discharge demand of the electric storage device at a time when the boost converter is operated in the continuous boost mode.
