Abstract

A charge controller is used for a vehicle equipped with a rotating machine, a main battery for storing electrical power supplied to the rotating machine, a power storage device, and a solar power generator. The charge controller includes a power converter, a first charging section, a step-up section, and a second charging section. The power converter is interposed between the solar power generator and the storage device. The first charging section controls the power converter to store electrical power generated by the solar power generator in the storage device. The step-up section steps up and outputs the power stored in the power storage device to the main battery. The second charging section controls the step-up section to charge the main battery with the power stored in the power storage device.
