Frequency tuning versus variable resonance circuit tuning
Dipl.-Ing. (TUM) Georg Heiland, Finepower GmbH and Dr.-Ing. Christof Ziegler, TDK Electronics AG present the development of an inductive charging station with the ability to operate as many different vehicle types as possible with correspondingly different receiver coils and battery systems in a trade publication of the newspaper “Elektronik Industrie” (all-electronics.de).
With the development of a universal inductive charging system, Finepower GmbH underlines its leading position in power electronics and battery charging. After many developments of off- and onboard chargers for industry and electric mobility, Finepower is already working on the improvement of tomorrow’s charging technology.
Inductive charging systems for electric vehicles are currently the subject of research, development and standardisation. Typical application examples are the contactless recharging of industrial trucks and electric vehicles in road traffic.
The most varied system properties of vehicles such as ground clearance, battery voltages, coil geometries, current carrying capacity, etc. mean that each manufacturer is currently striving for an inductive charging unit developed individually for a particular vehicle fleet. An inductive charging station with the ability to operate as many different vehicle types as possible with correspondingly different receiver coils and battery systems is currently being set up at Finepower as part of the research project “UnIndCha” (“Universal Inductive Charging”) funded by the Bavarian State Ministry of Economics & Media (StMWi).
TDK Electronics AG (formerly EPCOS AG) is involved in the project as a manufacturer of transmitter and receiver coils for inductive charging systems and pays particular attention to the electromagnetic compatibility (EMC) of universal systems. In addition, the Technical University of Munich (TUM), the department of energy conversion technology, and the Kempten University of Applied Sciences and the Technology Network Allgäu (TNA) support fundamental research work.
