Abstract
A method for estimating a battery aging state is provided. The method includes receiving measurement values of a battery from a battery management system, calculating factors representing change characteristics of each of a discharge voltage and a discharge current in each of charge/discharge cycles by using the measurement values of the battery; and estimating, based on an n-dimensional vector including the calculated factors, the battery aging state by using a machine learning model that is pre-trained by using, as an input vector, an n-dimensional vector including factors representing change characteristics of each of a discharge voltage and a the discharge current in each of charge/discharge cycles of each battery for training using measurement values of the battery for training.
