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.
Claims5
A charging apparatus comprising:
- a plurality of batteries;
- a set of relays 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 that includes the plurality of batteries and the set of relays, the electric storage device is configured to be chargeable by receiving an electric power that is supplied from an electric power supply outside a vehicle;
- a main relay that is provided between the electric storage device and an electric load of the vehicle, the main relay includes a first relay and a second relay, the first relay is connected to a positive electrode line of the plurality of batteries and the second relay is connected to a negative electrode line of the plurality of batteries;
- and
- a control device that is configured to control opening/closing of the set of relays, wherein
- the control device is configured to render the relay in the first state when the main relay is in an open state.
