A device and method for estimating life of a secondary battery

摘要

A device for estimating battery life of a secondary battery comprises a data input unit for receiving first battery life test data and second battery life test data for a secondary battery, the second battery life test data being determined under conditions that accelerate deterioration of the battery compared to conditions under which the first battery life test data is obtained, a data processing unit for calculating an acceleration factor from the first and second battery life test data and for estimating the life of the battery from the second battery life test data and the acceleration factor.
