New Dynamic Battery Model for Hybrid Vehicles and Dynamic Model Analysis Using Simulink

Abstract

Mathematical modeling and dynamic simulation of battery storage systems can be challenging and demanding due to nonlinear nature. Simulation in time domain could be time consuming as battery storage (BS) systems do not behave according to readily available mathematical functions. Economic advantages, partial sustainability and the portability of these units pose promising substitutes for backup power systems in hybrid vehicles, hybrid electricity power generation systems, telecommunication exchanges and computer networks. Though, there have been many research papers published in this area with complex mathematical models and simulation systems, each system has its own constraints and specific applications. The aim of this research paper is to present a suitable convenient, dynamic battery model that can be used to model a general BS system. The proposed new dynamic battery model has the capability to analyse the effect of temperature, cyclic charging/discharging, and voltage stabilization effects. Simulink has been used to study the characteristics of the system and the proposed system has produced very good successful results. ENGINEER, Vol. 47, No. 04, pp. 53-61, 2014
