Modeling Li-ion Battery Using Measurement Data

Abstract

A precise battery model is essential for battery management system to predict state of charge and cell balancing. The aims of this paper are improved Lithium-ion battery model and study behavior of Lithium-ion battery. In this paper a second-order equivalent circuit of battery lithium-ion is developed to use for Lithium-ion Nickel based battery. The model is developed and validated with experiment result in MATLAB/SIMULINK/SIMSCAPE, As the comparison, The developed model is capable to predict current-voltage performance accurately in battery management system.
