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 secondary battery to be estimated, the method including:

• acquiring a plurality of parameters relating to a state of the secondary battery to be estimated based on voltage data which is acquired in the secondary battery to be estimated or which is acquired by data acquired in a secondary battery;
• and
• based on a predetermined association between the plurality of parameters and a plurality of voltage regions or a plurality of capacity regions, sequentially acquiring at least one parameter exclusively selected from the plurality of parameters for each of the plurality of voltage regions or the plurality of capacity regions.

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 secondary battery to be estimated to execute:

• acquiring a plurality of parameters relating to a state of the secondary battery to be estimated based on voltage data which is acquired in the secondary battery to be estimated or which is acquired by data acquired in a secondary battery;
• and
• based on a predetermined association between the plurality of parameters and a plurality of voltage regions or a plurality of capacity regions, sequentially acquiring at least one parameter exclusively selected from the plurality of parameters for each of the plurality of voltage regions or the plurality of capacity regions.
