This article describes the conductive in-road charging system as developed in the
eRoadArlanda project, a pilot project for the development of in-road charging
system for both heavy and light vehicles intended for application in motorways.
The results of an analysis of measurements collected during the integration
tests of this system are presented and discussed. The results focus on the
end-to-end efficiency of the in-road charging system and aim to provide
researchers in the field with a reference for this technology and configuration
for use in the future development of such infrastructure. The analysis of the
measurement data addresses losses in the low-voltage side of the AC conductive
charging system as well as the vehicle-mounted isolated rectifier/converter
connected to the vehicle DC system. An exploratory analysis of data collected
over a 6-month testing period in varying weather conditions is used to provide
insight into factors affecting the overall efficiency of the system. A
discussion of the results includes the effects of cable dimensioning, rectifier
performance and placement, and the use of salt for deicing.
