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

A secondary battery state estimation system comprising:

• a degradation estimation portion that acquires a plurality of parameters relating to a state of a 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 thereby estimates a degradation degree of the secondary battery to be estimated,
• wherein the degradation estimation portion differentiates a search range when acquiring a first parameter among the plurality of parameters at a predetermined time and a search range when acquiring a second parameter that is different from the first parameter among the plurality of parameters at the predetermined time.

A secondary battery state estimation method performed by an electronic apparatus including 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
• differentiating a search range when acquiring a predetermined parameter among the plurality of parameters at a first time and a search range when acquiring the predetermined parameter at a second time that is different from the first time.
