SAE Congress Presentation Says 42-Volt Systems to Change the World

Two part presentation focuses on global impact of 42-volt automotive systems and service issues.

WARRENDALE, Pa., Feb. 26 /PRNewswire/ -- A technological revolution is underway as global automotive engineers are busy developing 42-volt electrical systems to replace current 14-volt vehicles. An Executive Panel will address the benefits and transitional challenges to adopting the 42-volt system during the SAE 2001 World Congress, March 5-8, Cobo Center, Detroit, Michigan.

"Power limits of current automobiles are almost maxed-out," says Norm Traub, Director of the SAE Strategic Alliance (SSA) 42-Volt Initiative. "Consumers want advanced safety, entertainment and communication features in their vehicles, and 14-volt systems can not deliver enough electricity. Forty-two volt systems will become a prerequisite for improved safety, comfort and convenience, as well as regulatory requirements for reduced emissions and fuel consumption."

According to Traub, transition to 42-volt systems will take an unprecedented, collaborative effort on behalf of the global automotive industry.

"Hundreds of automotive components will need to be reengineered to become 42- volt adaptable," Traub says. "Batteries, circuit protection devices, switches, wiring harness-you name it-will need redesigned. Dual voltage systems (14- and 42-volt) will be designed as an interim solution." "And there are service and repair issues associated with 42-volt. Technicians will need retrained and new diagnostic systems developed. It's a huge undertaking, but it must be accomplished."

Industry predicts dual voltage electrical systems will begin appearing in vehicles by 2005, with full implementation on all cars possibly taking up to 20 years.

"Challenges and Benefits of Transitioning to 42-Volt Systems" begins 9 a.m., Tuesday, March 6, in Room M3-31, Cobo Center. Part One, "Impact of the Global Economy on the Implementation of 42-Volt Electrical Systems," addresses opportunities and challenges related to the transition. Part Two, "Service Issues for 42-Volt Systems," focuses on repair issues. SSA is organizing the panel in partnership with the Service Technicians Society (STS).

The SAE 2001 World Congress, the world's largest showcase of automotive engineering technologies, attracts attendees from more than 50 countries. For more information, visit www.sae.org/congress or call 1-877-SAE-CONG (723-2664); outside the U.S. and Canada, call 1-724-772-4027.
