Method for Predicting State of Health of Battery Based on Numerical Simulation Data

摘要

A method for predicting a life state of a battery according to an embodiment of the present invention is a method for estimating a life state of a battery performed by a battery management system, Obtaining a numerical simulation database in which solution data of the battery is extracted and stored if the numerical analysis result is verified as a laboratory result through electrical and chemical analysis on the battery; Counting the number of times of charging or discharging when the deviation between the reference data read from the verified numerical simulation database and the measurement data read from the battery is within a predetermined range and the battery capacity satisfies a predetermined condition; And predicting a lifetime state of the battery using the number of times of charging or discharging and the classifier according to the learned machine learning algorithm.
