Abstract
A charge voltage controller for a chargeable and dischargeable energy storage device including an electrode assembly having a positive electrode and a negative electrode, is configured to control upper limit voltage applied to charge the energy storage device in accordance with at least one of charge time of the energy storage device, current inputted to the energy storage device, temperature of the energy storage device, and a state of charge of the energy storage device, to inhibit potential of the negative electrode from being lower than deposition potential at which metal ions transmitting and receiving an electric charge between the positive electrode and the negative electrode are deposited at the negative electrode. The deposition potential is variable in accordance with a state of charge of the energy storage device, and/or charge time of the energy storage device, and/or current inputted to the energy storage device, and/or temperature of the energy storage device.
