Dual Voltage Architecture Optimisation Through a Virtual Simulation Platform 2001-01-3340
Power demands in automotive electrical systems have significantly increased for the last few years, and this trend will soon lead to the same solution decided in the late 50’s, when 12V had replaced 6V. But this new transition will need a global vehicle approach specially in energy management techniques, which also takes into account transient phenomena. Today, the question is no more: « Why 42V ? » but « When ? » and « How ?».
Moreover, the answer to these questions is really specific to each car manufacturer. That is the reason why PSA automotive has decided, through a LEAR’s partnership, to develop a complete methodology, including numerical simulation. This methodology must achieve to define the best-in-class electrical architecture of different alternatives, once the final level of performance (in terms of equipment or functionality) has been estimated.
Relevant results from this virtual analysis based on the own specific model of a dual voltage network are commented in this paper, covering aspects like energy balance, transients, fault analysis and safety.
