Abstract

A battery degradation analysis support device is provided that supports analysis of battery degradation with higher analytical accuracy than conventional devices. [Solution] The battery degradation analysis support device (10) comprises a memory unit (14) that stores a knowledge base (14a) that registers the correlation between the time-varying patterns of peak characteristics in the dQ / dV curve during charging and discharging of the battery and battery characteristic information including physicochemical phenomena inside the battery or the battery characteristics, a time-varying pattern generation unit (12) that generates the time-varying pattern of peak characteristics in the dQ / dV curve from charge / discharge cycle data (31) of the battery to be analyzed, and a degradation interpretation presentation unit (13) that searches for battery characteristic information registered in the knowledge base (14a) by comparing the generated time-varying pattern of peak characteristics with the time-varying patterns registered in the knowledge base (14a), and generates and presents data interpretation hints (32) related to the degradation of the battery to be analyzed.
