Abstract
A method for evaluating a life of a secondary battery, including an evaluation condition input process of inputting a temperature, a charging rate, and a discharging rate to evaluate the life of the secondary battery, a data computation process of computing an evaluation period, in which a state of health of the secondary battery reaches a set range, a capacity degradation rate, and a direct current internal resistance change rate, and an acceleration factor calculation process of calculating an acceleration factor of the secondary battery using a first equation, the first equation being that the acceleration factor is equal to the direct current internal resistance increase rate divided by the capacity degradation rate.
