Electric and hybrid vehicles are still relatively new products and are undergoing developmental refinements as the technology moves towards maturity. There are challenges related to the fundamentals of the technologies, the availability of various materials and sub-systems, cost targets and customer demands. The technology is complex and multi-disciplinary involving system integration of diverse components. This course will cover the interdisciplinary aspects of electric and hybrid vehicles where engineers of various disciplines have to work together to develop the system. The fundamentals, design philosophies for electric and hybrid vehicles, component selection and sizing, and modeling and control strategies will be covered. Existing electric and hybrid vehicle models such as Nissan Leaf, Ford Focus, Tesla Roadster, Chevy Volt, Toyota Prius, Chevy Malibu, Ford Fusion etc. will be used as case studies. Participants will learn about the future trends in battery, power electronics and motor drive technologies.
