Abstract:
There is provided a secondary battery tester for testing a state of a secondary battery based on an impedance characteristic of the secondary battery. The tester includes: an impedance acquiring section configured to acquire an impedance value of the secondary battery; and a determining section configured to determine a state of a solid electrolyte interface (SEI) layer of the secondary battery based on the impedance value acquired by the impedance acquiring section.
