Abstract
Official abstract text for this publication.
A power unit is equipped with a power generator connected to an electric load, a first storage device connected to the electric load and the power generator, a second storage device connected to the electric load, the power generator, and the first storage device, and a charge control device that controls charge/discharge of the second storage device. The charge control device controls the discharge of the second storage device such that a power is supplied to the electric load and the first storage device when a predetermined condition corresponding to a high possibility of an increase in a power generation amount of the power generator is fulfilled, and controls the discharge of the second storage device such that a power is supplied to the electric load when the predetermined condition is not fulfilled.
First claim
