The drive technology of road vehicles is currently based, almost without exception, on fossil fuels. The combustion engine is used in all vehicle classes such as passenger cars, buses, and trucks. Due to the fact that internal combustion engines exceed the limit values for maximum particulate matter and nitrogen oxide pollution, the electrification of individual and commercial transport 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, and the incomplete charging infrastructure in the area of the federal trunk roads. The supplementation of stationary charging facilities with systems for continuous charging or energy transfer between vehicle and roadway during the journey is considered to be a purposeful solution for long-distance traffic.

The research project InductInfra, which is funded by the Federal Ministry of Transport and Digital Infrastructure from November 2020, aims to develop new structural engineering concepts and material systems for dynamic inductive power transmission and to fundamentally research their integration into the infrastructure. Vehicles draw the energy required for operation or rapid charging from an induction field via vehicle-integrated secondary coils. The induction field is generated by primary coils located in infrastructure-integrated induction modules. The fundamental development of the induction modules and the materials required for them as well as their permanent integration form the core of the proposed research project. In addition, the potential, operational safety, and economic efficiency of supplying the induction modules with regenerative energy will be determined.
