Abstract
When a use range of an SOC (State Of Charge) of a secondary battery is expanded, the use range of the SOC is expanded by increasing an upper limit value or decreasing a lower limit value of the use range of the SOC. The increasing the upper limit value or decreasing the lower limit value of the use range of the SOC is determined to a side causing a smaller increase in a degradation rate of the secondary battery, based on at least one of a cycle degradation characteristic that defines a cycle degradation rate in accordance with the use range of the SOC and a current rate of the secondary battery and a storage degradation characteristic that defines a storage degradation rate in accordance with the SOC and a temperature of the secondary battery, and a typical use condition of the secondary battery based on a use history of the secondary battery.
