Abstract

A method for detecting an abnormal fault of a battery, includes measuring cell data from battery cells included in a battery pack for a predetermined period of time; generating two-dimensional input data by mapping the cell data on a two-dimensional plane having a first axis corresponding to the period of time and a second axis corresponding to an index of each of the battery cells; inputting the two-dimensional input data into an abnormal fault detection model pre-trained to detect the abnormal fault in the battery; and determining whether an abnormal cell, having entered an abnormal state, among the battery cells, is present, based on an output of the abnormal fault detection model.
