A1

A device (1) for assessing the degree of degradation of secondary batteries assesses the degree of degradation of a secondary battery (2). The device is provided with a battery characteristic acquisition unit (61), a capacity estimation unit (62), and an assessment unit (63). The battery characteristic acquisition unit (61) acquires a battery characteristic that pertains to voltage transition in a prescribed voltage section in the secondary battery (2). The assessment unit (63) assesses the degree of degradation of the secondary battery (2) on the basis of the battery characteristic acquired by the battery characteristic acquisition unit (61) or a battery characteristic relation value that is calculated on the basis of the battery characteristic.
