Title: METHOD FOR PREDICTING STATE OF LIFE OF BATTERY ON BASIS OF NUMERICAL SIMULATION DATA
Abstract:
The present invention relates to a method for predicting a state of life of a battery on the basis of numerical simulation data. A method for predicting a state of life of a battery by a battery management system according to an embodiment of the present invention comprises the steps of: when a numerical analysis result is verified using a laboratory test result obtained through electrical and chemical analysis of a battery, acquiring a numerical simulation database obtained by extracting and storing solution data of the battery; counting the number of times of charging or discharging when a difference between reference data read from the verified numerical simulation database and measurement data read from the battery falls within a predetermined range and a battery capacity satisfies a predetermined condition; and predicting a state of life of the battery by using the number of times of charging or discharging and a classifier according to a pre-learned machine learning algorithm.
