CIRCE achieves, for the first time, ultra-fast power transfer without cables


The Aragon technological center CIRCE (Spain) has just achieved a milestone in the field of wireless energy transfer. The center has developed the first system capable of transferring power wirelessly to 300 kW, which is three times the capacity achieved two years ago.



With this advance the door opens to the ultra-fast inductive load of heavy electric vehicles, allowing the loading of these vehicles with a 60% reduction in time compared to current systems and without the need to connect any cables. In addition, the system improves usability to the driver and has a minimal impact on urban infrastructures and furniture when buried.



This new achievement has been obtained in the framework of the European project NIWE, funded by the European Commission through the Horizon2020 program, whose trajectory concludes this week after five years of life. Specifically, within this project the solution developed by CIRCE has been validated in the metallurgical industry by feeding furnaces for the iron smelting by induction.



In addition to being able to extend the new prototype of inductive load to other industries, its application in the short term is specially designed for the loading of large electric vehicles -such as trucks or buses- wirelessly for both urban and interurban routes. The operation is based on the circulation of electric current between two coils - one on the ground and one on the vehicle itself, generating a magnetic field that allows to place a vehicle on top of it, it begins to load without being accurate cables or connections. The system, being buried, causes a minimal visual impact on the image of the city and greatly facilitates usability by consumers.

Induction charging has a huge field of application, from systems for public transport, delivery companies, private homes to the industrial environment, where this type of load facilitates the automation of processes, providing a more stable and robust element than a network of conductive cables.



The solution obtained within the NIWE project constitutes another step that is added to the results achieved in the UNPLUGGED project, in which CIRCE worked until 2015. In it, a modular system was proposed to power 25 kW or 50 kW systems, according to the type of vehicle that accessed the loading system. The advance in this case is that the new solution, more powerful, is specially designed for the heavy vehicle, in this way the loading time decreases significantly. (Source: CIRCE)
