| description | A battery management system includes a usage history acquisition unit, a deterioration estimation unit, a battery load acquisition unit, a deterioration change degree identification unit, and a battery management unit. The usage history acquisition unit acquires usage history information. The deterioration estimation unit estimates a current deterioration state and a deterioration factor of the secondary battery based on the usage history information. The battery load acquisition unit acquires battery load information indicating a future battery load. The deterioration change degree identification unit identifies a deterioration change degree by using the current deterioration state, the deterioration factor and the battery load information of the secondary battery. The battery management unit uses the deterioration change degree to associate secondary batteries with future use modes so that an evaluation value indicating a degree of deterioration of the secondary battery in use devices becomes a minimum value. |
