Synthesis of important design criteria for future vehicle electric system

Abstract

In this article, we give a brief overview of future trends and corresponding stakeholder requests regarding the design of automotive electric and electronic (e/e)-architectures. While today's optimization is mainly based on the static design criteria of unit costs and weight, three dynamic design criteria are considered decisive factors in the future: Voltage stability, vehicle energy consumption and total cost of ownership. It is shown, how quantitative values for each criterion can be derived, on basis of which different designs of a potential future power supply system could be evaluated. Subsequently, their potential influences on the future system design is discussed.
