LISA4CL – Development and Grid Integration of an Inductive Charging System for City Logistics

Abstract:
For frequently used electric vehicles and fleets, short charging times and thus possibly short standing times are necessary. In this context, high-power inductive charging systems promise a massive increase in customer acceptance of electric vehicles. Against this background, a standard-compliant, inductive charging system with an output of 22 kW will be developed in the LISA4CL Laden – induktiv, schnell, autonom fr City Logistik project. This system will be tested practically in a logistics fleet as part of a field test. Another research topic of the project is the optimal grid and system integration of the charging system, because these are increasingly important as the penetration of charging infrastructure grows. In this regard, approaches to grid-oriented charging will be developed to ensure safe grid operation, and generation-oriented charging concepts will be developed to ensure the most economical and environmental operation of fleets. Firstly, these concepts are investigated by means of simulations. In the second step, they are validated in laboratory and finally tested practically in the aforementioned fleet field test.
