description A storage battery evaluating apparatus according to an embodiment includes a determiner, a corrector, a QV curve generator, an evaluator, and a feedbacker. The determiner determines a charging/discharging tendency of a storage battery based on measurement data including voltage data. The corrector corrects the voltage data based on a correction parameter. The correction parameter corresponds to at least one of the charging/discharging tendency and a degraded state of the storage battery. The QV curve generator generates a QV curve of the storage battery based on the voltage data which has been corrected. The evaluator evaluates the degraded state based on the QV curve. The feedbacker feeds back, to the corrector, the corrected parameter corresponding to the degraded state.
