A secondary battery deterioration determination apparatus configured to perform deterioration determination for a secondary battery (20), which is a determination target, includes a processor. The processor is configured to: calculate an estimated electric capacity of the secondary battery (20) based on at least a slope between any two points on a charging curve indicating a charging characteristic of the secondary battery (20); and perform the deterioration determination for the secondary battery (20) based on the estimated electric capacity which is calculated. The present invention can determine the deterioration of a secondary battery in a rapid and efficient way.

    판정 대상이 되는 이차 전지(20)의 열화 판정을 행하도록 구성된 이차 전지 열화 판정 장치는, 프로세서를 구비한다. 상기 프로세서는, 적어도, 상기 이차 전지(20)의 충전 특성을 나타내는 충전 곡선의 임의의 2점간의 기울기에 기초하여, 상기 이차 전지(20)의 추정 전기 용량을 산정하고, 산정된 상기 추정 전기 용량에 기초하여, 상기 이차 전지(20)의 열화 판정을 행하도록 구성된다.
