The invention provides a secondary battery degradation determination apparatus and a secondary battery degradation determination method. A secondary battery deterioration determination device configured so as to perform deterioration determination of a secondary battery to be determined is provided with a processor. The processor is configured to estimate an estimated capacitance of the secondary battery on the basis of at least a slope between any two points of a charging curve indicating charging characteristics of the secondary battery, and to perform a deterioration determination of the secondary battery on the basis of the estimated capacitance.

    本申请提供一种二次电池劣化判断装置以及二次电池劣化判断方法。以实施成为判断对象的二次电池的劣化判断的方式而被构成的二次电池劣化判断装置具备处理器。所述处理器被构成为,至少基于表示所述二次电池的充电特性的充电曲线的任意两点间的斜率,来对所述二次电池的推断电容量进行推算,并且基于被推算出的所述推断电容量来实施所述二次电池的劣化判断。
