MULTIVARIATE WAVELET-BASED BATTERY CELL SELECTION METHOD AND APPARATUS USING SAME

摘要

Provided is a battery cell selection method comprising the steps of: measuring a cell voltage for each cell while charging and discharging a plurality of cells with a preset current profile; performing multivariate wavelet transform by using a plurality of cell voltage measurement values as input variables; selecting at least two wavelet component values for the each cell to perform statistical analysis; and selecting at least two cells having high similarity of statistical analysis among the plurality of cells.;COPYRIGHT KIPO 2017
