The international climate targets up to 2050 call for a far-reaching decarbonisation of all sectors and a switch to renewable energies. This can only be achieved through extensive electrification of the heat and mobility sectors (sector coupling) and through efficient energy transmission and conversion systems [1], which must be considered and further developed as an overall system. The turnaround in energy and mobility will therefore continue to have a massive impact on activities in science and industry both nationally and globally in the coming decades. Germany has an industrial landscape that has been actively shaping the fields of energy technology and energy conversion for years. Basic research and application-oriented research projects thus complement each other and offer points of contact for many players in research and industry.
In this context, components (DC networks, vehicle electrical systems, charging infrastructure) and storage facilities as well as power electronic and control solutions for connection to stationary and mobile networks are of particular importance. The feasibility of the solutions always includes guaranteeing a defined longevity and reliability of the (electronic or power-electronic) components as well as questions about the quality of the energy supply. The electrification of vehicles is linked to the energy revolution. Solutions for highly efficient and compact electric vehicle drives as well as charging devices (on-board and off-board) and a sensible charging infrastructure must be researched taking into account the system requirements.
