Abstract
In a deterioration degree determination device for a secondary battery, a battery information acquisition unit acquires battery information related to the secondary battery, and a feasibility determination unit determines feasibility of determination of deterioration degree for each secondary battery based on the battery information and a feasibility determination reference prepared in advance. A battery characteristic acquisition unit acquires a battery characteristic related to transition of a battery state in a predetermined voltage section for the secondary battery for which the determination of the deterioration degree is determined to be feasible by the feasibility determination unit. A deterioration degree determination unit determines the deterioration degree of the secondary battery for which the determination of the deterioration degree is determined to be feasible, based on the battery characteristic acquired by the battery characteristic acquisition unit or a battery characteristic relationship value calculated based on the battery characteristic.
