Abstract: An evaluation value is calculated based on a history of currents in order to quantitatively evaluate unevenness of an ion concentration in a non-aqueous electrolyte of a secondary battery. An integrated evaluation value for each of the discharging side and the charging side are calculated. When the integrated evaluation value exceeds a positive threshold value, discharging of the secondary battery is restricted, and when the integrated evaluation value exceeds a negative threshold value, charging of the secondary battery is restricted.
