Resumen de: US20260266919A1
A data acquisition unit acquires use history data of a secondary battery and battery information for identifying a type of the secondary battery. A deterioration characteristic search unit searches a deterioration characteristic database based on the battery information to identify deterioration characteristic information including a storage deterioration characteristic, a charge deterioration characteristic, and a discharge deterioration characteristic of the secondary battery. An internal deterioration state analysis unit estimates a storage deterioration amount, a charge deterioration amount, and a discharge deterioration amount of the secondary battery based on the deterioration characteristic information identified by the deterioration characteristic search unit and the use history data acquired by the data acquisition unit. A reuse determination unit determines a secondary use destination after an end of primary use of the secondary battery based on a breakdown of the storage deterioration amount, the charge deterioration amount, and the discharge deterioration amount of the second battery.
