Abstract
A charging apparatus includes a plurality of batteries, a changeover relay that can be changed over between a first state where the plurality of the batteries are connected in series to one another and a second state where the plurality of the batteries are connected in parallel to one another, an electric storage device, a main relay that is provided between the electric storage device and an electric load of a vehicle, and a control device that controls the opening/closing of the changeover relay. The control device renders the changeover relay in the first state when the main relay is in an open state.
