Although hybrid powertrains have been on the market for little more than a decade, hybridization has quickly become one of the most successful alternative powertrains available today. Some OEMs estimate that up to 80% of their light-duty vehicles will require some level of hybridization to meet upcoming CAFE regulations in the United States. Additional market drivers, such as California's greenhouse gas legislation (now adopted or in process in 20 US states and two Canadian provinces) and a possible global agreement on greenhouse gas production at the end of 2009 may help to accelerate the process.

Basic information on hybrids is scattered among information sources, and is often difficult to synthesize. In this two-hour web seminar, energy storage systems, inverters, motor-generators, and DC-DC converters are explained, as well as design considerations for both light-duty and heavy-duty vehicle powertrains and developing trends such as plug-in, flywheel and hydraulic hybrids.

Is this Web Seminar RePlay for You?

This course is designed for the engineer, manager, or marketing professional who needs a quick overview of the design and manufacture of hybrid vehicle powertrains. Industry professionals who want a broad yet concise overview of the technological aspects of current and upcoming hybrid powertrains will benefit. Anyone who is unfamiliar with basic hybrid technology, yet whose job will be impacted by hybrid vehicles in the future, will benefit from this web seminar. A basic understanding of road vehicle construction and operation will be helpful.
