Modeling of lithium-ion battery considering the materials degradation properties of its cells

Abstract: A reconfigurable mathematical model of a lithium-ion battery (LIA) based on the Schaeferd and Thevenin models is devel-oped. The capacity and the active resistance of the battery are used as variable parameters. The algorithm to determine these parameters at the current moment of time allows taking into account the influence of such an important phenomenon as the degradation of material properties of LIA elements on the bat-tery characteristics. The modeling results reflect the high effi-ciency of the proposed approach.
