A key Delphi Automotive Systems (NYSE:DPH) engineer will discuss the automotive community's efforts to provide standardization and define technical challenges facing the implementation of dual and 42-Volt electrical systems during Europe's leading automotive and transportation technology conference, the 33rd annual International Symposium for Automotive Technology and Automation (ISATA) conference.

Norman Traub, technology integration manager for Delphi's Packard Electric Systems division, will present a keynote address, "Dual/Higher Voltage: A Global Opportunity," at the conference here Sept. 26.

"The automotive industry is on the verge of making enormous breakthroughs in mobile multimedia, safety, drive-by-wire systems, and other technologies that require increased electrical energy and power needs," Traub said. "Vehicle manufacturers are faced with the challenge of providing more electrical power to offer increasingly fuel efficient and safer vehicles with additional customer features. The rate of growth of electrical load in cars has been increasing in recent years, and at some point, it will cease to be economical to supply this load given today's automobile electrical supply."

For approximately the last five years, vehicle manufacturers and their suppliers have been investigating the best way to achieve a substantial increase in the electrical supply capacity, and the most cost effective way to provide the higher amounts of energy being forecasted. Delphi, a world leader in the design, development and manufacture of power and signal distribution systems and the largest global volume supplier of automotive batteries to vehicle manufacturers, has been developing solutions and electrical architecture alternatives that will meet the new requirements of dual and 42- Volt systems.

"Vehicle manufacturers and suppliers are in agreement that global cooperation and standardization will be needed," Traub said. "Today's nominal voltage when the generator is running is 14 volts, and a consensus has formed that an additional voltage level is required -- nominally 42 volts. The change is expected to significantly enhance the use of power electronic components and systems on automobiles."

Among the organizations fostering this consensus is the Massachusetts Institute of Technology (MIT)/Industry Consortium on Advanced Automotive Electrical/Electronic Components and Systems. Delphi is a charter member of this organization, begun by MIT in 1996 with 11 vehicle manufacturers and component suppliers. It has now grown to include 44 companies around the world. The consortium sponsors research at MIT on subjects related to dual voltage electrical systems and holds three meetings per year among member companies.

Although vehicle voltage levels are being standardized, the vehicle architecture is not being standardized. During his presentation, Traub will outline several electrical architecture alternatives, in addition to addressing technical issues, challenges, transition and associated 42-Volt system implementation issues.

Traub has been integral in Delphi's research and development initiatives related to 42-volt electrical systems. He holds four U.S. patents and numerous research reports/publications in the areas of automotive multiplexing, large industrial drive systems, electric cars and automotive safety/security systems.

Founded in the early 1970s, the International Symposium for Automotive Technology and Automation has provided the automotive engineering community with a platform for open debate about the latest innovations and cutting-edge ideas. ISATA has provided a European forum for engineers from major international automakers, suppliers and research establishments to discuss the latest innovations in product development and manufacturing processes, and the latest advances in technology.

Multi-national Delphi Automotive Systems, with headquarters in Troy, Mich., USA, Paris, Tokyo and Sao Paulo, Brazil, is a world leader in mobile electronics and transportation components and systems technology. Delphi's three business sectors -- Dynamics & Propulsion; Safety, Thermal & Electrical Architecture; and Electronics & Mobile Communication -- provide comprehensive product solutions to complex customer needs. Delphi has approximately 216,000 employees and operates 179 wholly owned manufacturing sites, 41 joint ventures, 53 customer centers and sales offices and 31 technical centers in 39 countries.
