Design And Simulation Of A Hybrid Electric Vehicle's Energy Management System Using PV, Fuel Cell And Super Capacitor

Abstract

In the context of global warming, clean energy generation and effective utilization of renewable sources like solar energy, fuel-cells are needed to develop hybrid electric vehicle that over comes conventional vehicle issues global warming and increasing price of fuel and also to reduce the use of fossil fuel. In this work, we tried to develop a efficient Energy Management System (EMS) for a photovoltaic cell, fuel cell based hybrid electric vehicle with combination of supercapacitor and battery, which is known as PVFCHEV. The vehicle energy management system is designed using Matlab/Simulink compiler. In order to supplement the use of solar energy in the face of rapidly changing power interests, the distinction of solar energy must be considered. The solar energy used as auxiliary power source for the vehicle whereas, the primary source is fuel cell. Supercapacitor is used to boost the total power of the vehicle system while the system needs more power to accelerate. There also dc/dc converters are used to step up individual voltage of each source. A dc/ac converter is used before an three phase induction motor to supply the power on it. The valuable test results reveal that the planned vehicular force framework and the EMS function admirably at different sunlight-based radiations and battery states. Under the guidance of the EMS, the force framework demonstrates viability and adaptability in a variety of situations. Finally, with the proposed energy management system it can provide reasonably better fuel economy and less emission than a commonly used power following control procedure.
