Emerging Technologies of Hybrid Electric Vehicles

Emerging Technologies of Hybrid Electric Vehicles Chris Mi, Ph.D, Associate Professor, Senior Member, IEEE 4901 Evergreen Road, Dearborn, MI 48128-1491 Tel: (313)583-6434, email: chrismi@umich.edu Abstract: One of the fastest growing automotive fields, hybrid electric vehicles (HEVs) presents both opportunities and challenges HEVs are more fuel-efficient and environment friendly compared to conventional vehicles Optimizing the power intake in HEVs allows the engine operation to be kept within the range designed for best fuel economy and lowest emission, while the motor/generator system either provides additional power input, or generates electricity using the excessive power from the engine It also recovers the kinetic energy in braking or coasting These advantages have attracted worldwide development interests for HEVs in the automotive industry Hybrid vehicle sales have exceeded $250k per year with 14 models available in 2007 Experts predict that hybrid vehicles will take at least 10% of the total vehicle market share in the next years, and as a result, could affect 200,000 jobs in automotive related industries This presentation will look at the enabling technologies in the HEV field:        The pros and cons of HEVs Parallel, series, and planetary gear architecture Energy storage challenges Power electronics Plug-in and what it means Emerging issues in HEV New opportunities in HEV related fields Bio: Dr Chris Mi is assistant professor of electrical and computer engineering in the University of Michigan – Dearborn, College of Engineering and Computer Science He regularly offers a graduate course in electric and hybrid vehicles He has also taught courses and led seminars on the subject for the Society of Automotive Engineers (SAE) and the Institute of Electrical and Electronic Engineers (IEEE) Dr Mi has conducted extensive research and published more than 60 articles on power electronics, motor drives, electric and hybrid vehicles In addition to his position at UM-Dearborn, he is the vice chair of the IEEE Southeast Michigan section Dr Mi holds a BS and an MS degree from Northwestern Polytechnical University, Xi’an, China, and a Ph.D degree from the University of Toronto Dr Mi worked with General Electric Company from 2000 to 2001 Dr Mi won the “National Innovation Award 国国国国国国国国” in 1992, the “Government Special Allowance 国国国国国国” in 1994, and was listed in Marquis “Who is Who in America.” Dr Mi is the winner of the 2005 “Distinguished Teaching Award” of University of Michigan Dearborn He is also a recipient of the 2007 IEEE Region “Outstanding Engineer Award,” and 2007 “IEEE Southeastern Michigan Section Outstanding Professional Award.” He is a Semifinalist of the 2007 SAE Environmental Excellence in Transportation (E2T) Award Dr Mi has been nominated for the IEEE Distinguished Lecturer Award and the IEEE Fellow
