Battery management devices and methods

Abstract

The battery management device according to the scheme of the invention comprises a data acquisition unit configured to acquire voltage data relating to voltage variation over time for each of the battery cells, a preprocessing unit configured to acquire voltage data reconstructed at predetermined intervals from a dataset containing voltage data of each of the battery cells, using a data decomposition algorithm, a noise processing unit configured to generate battery cell data by performing noise processing based on the characteristics of the reconstructed voltage data, and an abnormal cell detection unit configured to detect abnormal battery cells based on the voltage deviation of each battery cell data.
