The development of innovative automotive systems is determined by the demand for cut in fuel consumption and increase in fuel efficiency, reduction of environmental pollution and comfort improvement. A basic condition for such developments is the introduction of a 42V power supply in future vehicles. The characteristics of future power supplies and the resulting consequences for the system, the components and the whole vehicle power supply architecture need standardisation in different areas. The standardisation of the 42V PowerNet started in 1996 as a national German project and was conducted by the 'Forum Bordnetzarchitektur' (Forum Vehicle Electrical Systems Architecture). In 1997 VDA (Association of German vehicle manufacturers and suppliers) and FAKRA (German standardisation body for vehicle applications) charged and co-financed this forum to continue the work and prepare a basic proposal for the inclusion in the international standardisation work of ISO as a new project. The forum prepared a working draft in close co-operation with the MIT/Industry Consortium and finished the work at the beginning of year 2000. The draft was submitted to ISO where its technical committee TC22 (Road vehicles) charged its subcommittee SC3 (Electrical and electronic equipment) to conduct the work within a newly established working group (WG 14). End of 2002 this WG14 will have finished the main technical work of the envisaged standard and after some following voting procedures at ISO level the standard will be finally published end of 2003. The electrical stress for the vehicle components is addressed in the standard IS0 21848 and this paper gives details about the status of the standardisation work.
