Original Title

Extraction of RC parameters for the ECM model of the Li-Ion battery

English Title

Extraction of RC parameters for the ECM model of the Li-Ion battery

Type

Original Abstract

This paper deals with the issue of extracting the parameters of a Li-ion battery's equivalent electrical circuit using Electrochemical Impedance Spectroscopy. It examines the principle of the EIS method and possible procedures for extracting the equivalent circuit. The study is complemented by the development of a free desktop application capable of extracting these parameters, with its output format directly aligning with the required inputs for the Ansys Fluent simulation software.
