Inductive dynamic energy supply of vehicles via road traffic infrastructure

The drive technology of road vehicles is currently based, almost without exception, on fossil fuels. Due to the exceeding of limit values for the maximum fine dust and nitrogen oxide pollution caused by combustion engines, the electrification of individual and commercial traffic is being pushed forward. In particular, the development of alternative drive strategies for long-distance traffic is still in its initial phase. Key problem areas include the lack of range, battery size, and weight, as well as the incomplete charging infrastructure in the area of the federal trunk roads.

A target-oriented solution for long-distance traffic is the supplementation of stationary charging facilities with systems for continuous charging or energy transfer between vehicle and roadway during the journey. This will make it possible to provide electric vehicles with virtually unlimited range, moderate battery size, and lower battery weight.

The "InductInfra" research project aims to develop new structural engineering concepts and material systems for dynamic inductive power transmission and to fundamentally research their integration into the infrastructure. While driving, vehicles draw the energy required for operation or rapid charging from an induction field generated by induction modules integrated into the infrastructure.

The fundamental development of these modules and the materials required for them as well as the technologies for their permanent integration into the transport infrastructure form the core of this research project. In addition, the potential, operational safety, and economic efficiency of supplying the induction modules with regenerative energy will be determined.
