Inductive wireless energy transfer is a future-proof way of charging electric vehicles, especially for applications in public spaces. A major advantage over wired charging is the convenience for the user and the ease with which it can be automated. Initially, this charging technology is likely to be used in inner-city fleet and taxi transport and in autonomous driving applications.
The technology: An inductive charging system consists of a road-side component and a vehicle-side component. Energy is transferred contactlessly from the road surface to the parked vehicle via an air gap using magnetic coils. Inside the vehicle, the electrical energy is transferred to the high-voltage battery via power electronic circuits.in wireless charging is a key factor for competitiveness compared to wired charging.
A further aim of the field test and its evaluation is to identify opportunities for optimising the inductive charging system as a result of its operation. The results will be used in the future development of contactless energy transfer systems.Another focus of the LISA4CL research project was the development of charging concepts for electric vehicles, in particular for fleet applications.
