Hybrid powertrains have been on the market for more than a decade and have become one of the most successful alternative powertrains available today. More than a million hybrids are sold globally per year, primarily in Japan and the US. Some OEMs estimate that up to 80% of their light-duty vehicles may require some level of hybridization to meet upcoming CAFE regulations in the United States. Hybrids are also starting to make inroads into markets in Europe, and have recently been introduced to Chinese and Indian markets, among others.

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.

Learning Objectives
By connecting with this web seminar, you will be able to:

  • Describe the efficiency improvements that hybrid vehicles achieve with respect to conventional vehicles
  • Identify common components of hybrid powertrains
  • Recognize basic layouts utilized in light, medium, and heavy-duty hybrid vehicle powertrains
  • Compare the advantages and disadvantages of different hybrid architectures
  • Summarize hybrid powertrain applications that are on the market today
  • Explain upcoming HEV developments

Who Should Attend
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 course. A basic understanding of road vehicle construction and operation will be helpful.

Registration Information
Registration for this live web seminar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access (at least 56K) and a telephone. The fee includes one connection to the conference calls (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the presentations, class session recordings, supplemental materials, and assignments.

Registrations will be accepted until 5:00 p.m. the day before the start of the web seminar, but early registration is encouraged to allow for pre-course set-up and instructions.

*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this web seminar. If your country is not listed, you may still connect using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).

Although WebEx Training Manager will automatically launch when you join the web seminar, you or your system administrator are encouraged to download the plug-in in advance to help ensure successful setup. Click here, then follow the onscreen instructions.

NOTE: The course presentation will be recorded and made available for 30 days to those who register by the deadline.
