Alternative electrical distribution system architectures for automobiles
- Massachusetts Inst. of Tech., Cambridge, MA (United States)
At present most automobiles use a 12 V electrical system with point-to-point wiring. The capability of this architecture in meeting the needs of future electrical loads is questionable. Furthermore, with the development of electric vehicles (EVs) there is a greater need for a better architecture. In this paper the authors outline the limitations of the conventional architecture and identify alternatives. They also present a multi-attribute trade-off methodology which compares these alternatives, and identifies a set of Pareto optimal architectures. The system attributes traded off are cost, weight, losses and probability of failure. These are calculated by a computer program that has built-in component attribute models. System attributes of a few dozen architectures are also reported and the results analyzed. 17 refs.
