Abstract

2 Abstract: The environmental aspect like oil depletion, global heating and CO2 gas emissions have become a concern and have propelled the development of an efficient and extendable energy management system (EMS) using fuel cell and battery sources for Hybrid Electric Vehicles. In this paper, a poser of a hybrid electric vehicle with energy management system with multiple source of energy is developed and analyzing the performance of HEV on Matlab. The multiple sources of energy, such as a battery and fuel cell (FC), EMS and power controller are designed and modelled using MATLAB. The developed control strategies continuously support the EMS of the multiple sources of energy for a vehicle under normal load conditions. The performance of the proposed system is analyzed in terms of vehicle speed and Load power. These study results suggest that the proposed control technique provides an efficient and feasible EMS for light electric vehicles. I. INTRODUCTION Around 90% of today's automobiles run on petroleum based product, which are estimated to be depleted by 2050. Moreover, current automobiles utilize only 27% of the energy released from petroleum and rest is wasted into the atmosphere. Despite recent efforts to improve fuel efficiency and reduce toxic emissions in cars, emissions have continued to increase steadily in the past two decades. For preservation of gasoline for future and increasing the efficiency of vehicle an electric vehicle can be a major breakthrough. An electric vehicle is pollution free and is efficient at low speed conditions mainly in high traffic areas. But battery charging is time consuming. Moreover, it cannot provide high power required by drives during high speed conditions or in slopes of hilly areas. Therefore the combination of fuel cell and lithium ion battery is one of the best options for gaining high performance in electric vehicle. Gasoline engine proves its efficiency at higher speeds in high ways and waste a lot of energy in urban areas. A hybrid electric vehicle solves these problems by combining the fuel cell and lithium ion battery and uses both the power sources at their efficient conditions. The objective of this project aims at better utilization of fuel energy and reduces dependence on non- renewable resources using latest technology. The implementation involves development of HEV that uses battery as well as fuel cell power for propulsion of vehicle.
