Modeling of lithium-ion battery using MATLAB/Simulink

Abstract

Lithium-ion battery is potentially to be adopted as energy storage system for green technology applications due to its high power density and high energy density. An accurate battery model in simulation platform is very important to design an efficient battery-powered system. In this paper, an electrical battery model is developed in MATLAB/Simulink. The structure of model is explained in detail, and a battery model for a lithium ferro phosphate battery is presented. The developed battery model is validated from the experiment results. From the comparison, it reveals that the developed model is capable of predicting current-voltage performance accurately. Although the model has been developed for lithium ferro phosphate battery, it is expected that it can be applied for other types of battery.
