Electric drives are found in hybrid, plug-in hybrid, and hydrogen fuel cell vehicles, as well as battery electric vehicles. More than two million hybrid vehicles worldwide utilize electric drive components, and battery technology has matured enough to enable major manufacturers to develop light-duty and commercial electric vehicles for mass production and sale beginning in 2010-2012. It is also likely that many conventional vehicles will incorporate some form of idle-stop or stop-start system comprised of a low-output electric drive, as an integral part of efforts to meet U.S. CAFE fuel economy standards and EU CO2 emission requirements.

Industry professionals who are looking for a general understanding of the structure and components of vehicular electric drives will benefit from this course, which will cover theory, design, operation, and diagnostics of all major components used in electric drives (battery packs, inverters, motor-generators, DC-DC converters, and charging apparatus) as applied to all forms of vehicles, including charge-sustaining hybrids, plug-in hybrids, fuel cell hybrids, and battery electric vehicles. Battery chemistry, charging systems, power conversion, switching techniques, and traction motor construction will be discussed in detail.

Is this Web Seminar RePlay for You?

Powertrain engineers, electrical engineers, project planners, project managers, technical writers, safety officers, component specialists, component suppliers, and anyone else who is professionally impacted by the development of electric vehicle technology will be able to use this information to help them transition to working with electric drives. Participants should have a basic knowledge of electric circuits. This is an introductory course; a mechanical or electrical engineering degree is helpful but not necessary.
