Abstract
An inspection method for a secondary battery according to the invention includes: a first aging treatment process for performing aging treatment on the secondary battery that has initially been charged at a first temperature; a first voltage measurement process; a second aging treatment process for performing the aging treatment on the secondary battery at a second temperature; a second voltage measurement process; a self-discharge amount computation process; a non-temperature dependent failure determination process for determining non-temperature dependent failure that does not depend on a relationship between a self-discharge amount and a temperature in accordance with the measured self-discharge amount; and a temperature dependent failure determination process for determining temperature dependent failure that depends on the relationship between the self-discharge amount and the temperature in accordance with the self-discharge amount, temperature dependency of which is suppressed.
