Abstract
The development of innovative vehicle systems is driven by the
demand for improvement in comfort, reduction in fuel consumption,
environmental protection and an increase in efficiency. A resultant
trend is the substitution of mechanical systems by electrical
solutions. A basic requirement is an optimized electrical power
supply. During the development of the future electrical power
supply, the following changes can be observed: 1) High power
components require higher voltages. As a result, multi-voltage
electrical power supply systems will appear. 2) Demands for
increased availability and reliability require the introduction of
state monitoring, redundant paths, components and functions. 3) The
relationship between electrical load requirements, deliverable
power and fuel consumption, force the introduction of electrical
power supply management.
These trends will be discussed, and the consequences of a future
electrical power supply architecture derived from it. Through
examples, practical possibilities are shown.
