Implementing the functional requirements for determining the optimal arrangement of a distributed charging infrastructure

The optimized and reliable operation of future traffic by intelligent control systems will need to take into account boundary conditions that arise from alternative drive concepts. New challenges will need to be mastered when it comes to corresponding energy systems, control of operations, and communication interfaces, such as needed for the sufficient energy supply of traffic participants. However, they will need to be conformed to existing systems, technologies, and infrastructure to allow the common operation and positioning of charging elements with minimum interference between different modes of transport. Funded by the German Federal Ministry of Transport, Building and Urban Development (Bundesministerium für Verkehr, Bau und Stadtentwicklung) the project emil (Elektromobilität mittels induktiver Ladung – electric mobility via inductive charging) will integrate an inductive vehicle charging system and a compatible prototype bus fleet into Braunschweig's traffic infrastructure. This paper describes the methodic approach and the implementation of functional requirements in a traffic simulation tool that are required for an evaluation of future urban road traffic with an increased rate of electric vehicles. The modifications can subsequently be used to determine the optimal placement of the corresponding charging infrastructure with consideration of conventional traffic demand.
