A degradation state of a lithium-ion battery is determined on the basis of information about a voltage change in the lithium-ion battery obtained in a diagnosis mode in which the lithium-ion battery is successively charged and discharged at a constant power value. The constant power value in the diagnosis mode preferably may vary with the power storage amount and the temperature of the lithium-ion battery. As the information, the degree of a voltage drop in the lithium-ion battery obtained during the discharge can be used.
