The drive technology of road vehicles is currently based almost exclusively on fossil fuels. Due to the exceeding of limits for maximum particulate matter and nitrogen oxide pollution by combustion engines, the electrification of individual and commercial transport is being driven forward. In particular, the development of alternative drive strategies in the long-distance transport sector is still in its initial phase. Key problem areas include the lack of range, battery size and weight, and the patchy charging infrastructure on federal highways.
Supplementing facilities for stationary charging with systems for continuous charging or energy transfer between the vehicle and the roadway while driving is seen as a target-oriented solution approach in the long-distance transport sector. This will make it possible to provide electric vehicles with a virtually unlimited range, moderate battery size and lower battery weight.
As part of the "InductInfra" research project, new structural engineering concepts and material systems for dynamic inductive energy transmission are to be developed and their integration into the infrastructure fundamentally researched. While driving, vehicles obtain the energy required for operation or fast charging from an induction field generated by induction modules that are 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 reliability and economic viability of supplying the induction modules with regenerative energy will be determined.
