In 1994, members of the automotive community met at Massachusetts Institute of Technology (MIT) in the USA and SICAN GmbH in Hannover, Germany to debate and propose the next generation electrical system that could provide the power levels being forecasted for the near future. In 1996 a proposal was set forth to raise the voltage level of the future automobile from its current nominal value of 14V (egine running) to 42V. Because there are so many electrical subsystems in today's 14V vehicles, it will be much more difficult to make the transition to a single higher voltage (42V) electrical system than it was for the 6V to 12V increase of almost 50 years ago. A dual voltage (14V/42V) electrical system will, therefore, be the next step. The paper describes the process, challenges and progress toward developing a new connection system to the battery. Prototype parts have been tooled to allow performance testing with company specific, harness connection proposals. Because of the packaging restrictions associated with some vehicles, several European companies are still evaluating alternative design possibilities. Since Toyota is already in production with 42V batteries, another 42V battery connection exists based on a threaded stud design. Toyota continues to evaluate a flat blade design and is awaiting performance and cost information before making a decision on changing from their current design. Performance requirements have been converted into a SAE specification J 2622. At the writing of this paper, the document was undergoing it's final editing and was being prepared for balloting by the SAE Electrical Distribution Systems Committee. This specification will describe test methods and acceptance requirements for terminal electrical, connector mechanical, connector electrical and connector environmental conditions. Pending approval of the specification by SAE International, it will be offered to ISO and IEC for consideration as an international standard.
