International standard for future automotive 42 V supply voltages (PowerNet)

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 42 V 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 electrical stress for the vehicle components is addressed in the standard ISO 21848 and this paper gives details about the status of the standardisation work. (C) 2003 Elsevier Science B.V.
