Challenges
The potential for electromagnetic interference of wireless power transfer (WPT) generates controversial discussions among professionals in organizations regulating electromagnetic compatibility (EMC). For dynamic wireless power transfer (D-WPT), there are no standardized measurement or certification procedures available. In fact, a lack of fundamental data of the electromagnetic emissions of D-WPT systems prevents theoretical analysis of the potential interference and emc. Meanwhile, different actors in normative international organizations are trying to establish lower emc limits for WPT-systems, which would essentially render the technology uncertifiable.
The nature of D-WPT-systems complicates the evaluation furthermore because each installation is build with the road and differs in details, which can influence the overall emissions. Therefore, only an evaluation of the potential emissions during the design phase allows changes with reasonable effort.
Goals
The goal of the project MAGNET-D is the development und evaluation of simulative methods for systematic analysis of the interference potential of D-WPT systems for electric vehicle charging as a basis for economic design and certification.
Realization
During the project, simulation models will be validated through physical models. A size-scaled version of a D-WPT system will be developed which, will be as small as possible while still emitting measurable emissions. This model can fit in an emc-chamber where it will be measured and the data helps to optimize the simulation model. Once the simulation model is validated this way, the method allows analysis of a number of chosen scenarios. In these scenarios, potential interference of the D-WPT system with sensitive installations at airports or hospitals will be evaluated.
