Secondary battery state estimation system, secondary battery state estimation method, and program

A secondary battery state estimation method performed by an electronic apparatus comprising a process portion that estimates a degradation degree of a predetermined substance contained in an electrode of a secondary battery to be estimated, the method including:

• a region acquisition step of acquiring a voltage region or a capacity region in accordance with the predetermined substance;
• and
• a degradation estimation step of determining whether or not estimation of the degradation degree of the predetermined substance is performed based on a determination result on whether or not voltage data that is acquired in the secondary battery to be estimated or that is acquired by data acquired in a secondary battery satisfies a predetermined condition in the voltage region or the capacity region acquired by the region acquisition step.

A computer-readable non-transitory recording medium that records a program causing a computer of an electronic apparatus comprising a process portion that estimates a degradation degree of a predetermined substance contained in an electrode of a secondary battery to be estimated to execute:

• a region acquisition step of acquiring a voltage region or a capacity region in accordance with the predetermined substance;
• and
• a degradation estimation step of determining whether or not estimation of the degradation degree of the predetermined substance is performed based on a determination result on whether or not voltage data that is acquired in the secondary battery to be estimated or that is acquired by data acquired in a secondary battery satisfies a predetermined condition in the voltage region or the capacity region acquired by the region acquisition step.
