Abstract

This tutorialfocuses on energy conversion and utilization in hybrid electric vehicles (HEV).The tutorial reviewsthe fundamentals of hybrid-electric vehicles, covering reasons for hybridization, energy analysis, architectures and components, energy modeling, vehicle simulation, energy optimization strategies, and supervisory control of HEVs. These topics are integrated though a progression of examples leading to the simulation, supervisory control, and energy optimization of a complete HEV.

The tutorial achieves the following objectives:

Analyze and quantitatively evaluate energy consumption in road vehicles. Relate energy usage in road vehicles to fuel economy.
Understand the concept and potential benefits of drivetrain hybridization strategies; develop and use mathematical models of energy storage and energy conversion subsystems used in hybrid vehicles.
Develop a methodology for constructing general models of energy storage and power flow processes in hybrid vehicles, and implement the methodology to create building blocks for hybrid vehicle simulators using Matlab/Simulink.
Learn the basic principles of energy management and supervisory control strategy for optimal energy storage in hybrid electric vehicles.
Synthesis of HEV analysis and simulation through an HEV design and optimization of fuel economy using simulation environment in Matlab/Simulink.
Introduction to optimal energy management of hybrid powertrains

Biographical sketch of Giorgio Rizzoni

Giorgio Rizzoni, the Ford Motor Company Chair in ElectroMechanical Systems, is a Professor of Mechanical and Aerospace Engineering and of Electrical and Computer Engineering at The Ohio State University (OSU). He received his B.S. (ECE) in 1980, his M.S. (ECE) in 1982, his Ph.D. (ECE) in 1986, all from the University of Michigan. Since 1999 he has been the director of the Ohio State University Center for Automotive Research (CAR), an interdisciplinary university research center in the OSU College of Engineering. His research activities are related to modeling, control and diagnosis of advanced vehicles, energy efficiency, alternative fuels, the interaction between vehicles and the electric power grid, vehicle safety and intelligence, and policy and economic analysis of alternative fuels and vehicle fuel economy. He has contributed to the development of graduate curricula in these areas, and has served as the director of three U.S. Department of Energy Graduate Automotive Technology Education Centers of Excellence: Hybrid Drivetrains and Control Systems (1998-2004), Advanced Propulsion Systems (2005-2011, and Energy Efficient Vehicles for Sustainable Mobility (2011-2016). Since January 2011 he has served as the OSU Site Director for the U.S. Department of Energy China-USA Clean Energy Research Center - Clean Vehicles.Prof. Rizzoni is a Fellow of SAE (2005), a Fellow of IEEE (2004), a recipient of the 1991 National Science Foundation Presidential Young Investigator Award, and of many other technical and teaching awards.

The OSU Center for Automotive Research

The OSU Center for Automotive Research, CAR, is an interdisciplinary research center in the OSU College of Engineering founded in 1991 and located in a 50,000 ft2 building complex on the west campus of OSU. CAR conducts interdisciplinary research in collaboration with the OSU colleges of Engineering, Medicine, Business, and Arts and Sciences, and with industry and government partners. CAR research aims to: develop efficient vehicle propulsion and energy storage systems; develop new sustainable mobility concepts; reduce the impact of vehicles on the environment; improve vehicle safety and reduce occupant and pedestrian injuries; increase vehicle autonomy and intelligence; and create quieter and more comfortable automobiles. A team of 50 administrative and research staff supports some 30 faculty, 100 graduate and 250 undergraduate students, and maintains and makes use of advanced experimental facilities. Dr. Rizzoni has led CAR for over a decade, growing its research expenditures from $1M per year to over $10M today, and engaging CAR in a broad range of technology commercialization activities, start-up company incubation and spin-out as well as providing a broad range of engineering services to the automotive industry.CAR is also the home of the OSU Motorsport program, which supports the activities of 6 student vehicle competition programs: the Buckeye Bullet (holder of all current electric vehicle land speed records), EcoCAR 3 hybrid-electric vehicle team, FSAE, Baja SAE, Buckeye Electric Motorcycle Racing Team, and Supermileage SAE.
