High speed detecting and identification for car charging on electric roads

Sammanfattning: The constantly increasing awareness of protecting the environment has put electrical roads in the spotlight as an alternative solution to fossil driven means of transport. Dan Zethraeus has developed an innovative idea for a prototype electrical road which conductively supplies power to the cars whilst driving. The concept is to place a line of short rail segments in the middle of the drive lanes where each rail can have either grounded or positive polarity. The aim of this thesis work is to find solutions for the timing, detection and identification of cars so that the positive conductive rails are switched on correctly. The possible electromagnetic interference from the road is to be investigated and the communication methods adjusted accordingly. Finally, a demonstrator is built as a proof of concept for illustrating and testing the presented solution. This report starts by presenting possible theoretical solutions for the detection and identification. Experiments that are set up to further analyse the most promising methods, and also the construction of the electronics for the detection and identification modules of the demonstrator follow. Furthermore, a simulation setup for analysis of the electromagnetic interference is tested. The complete solution and the whole setup of the demonstrator is presented in the last part. Results are presented for the performance of the demonstrator when tested on a real car driving at 30 km/h. This thesis work is a collaboration between the Division of Industrial Electrical Engineering and Automation (IEA) and the Department of Electrical and Information Technology (EIT) at Lund University.
