Brusa increase the power of their Inductive Charging System

BRUSA Elektronik AG is known for its innovative power-electronics solutions for the demanding automotive sector. To meet growing market demands, we have already started developing the next generation of our Inductive Charging System (ICS). With the increasing capacity of electric vehicle batteries and given the power-grid characteristics in North America and Asia, at 7.2 kW the ICS 2 will boast twice the charging power – yet will have the same compact footprint. This immense increase in power density has been achieved thanks to a special technology patented by BRUSA. An initial prototype of the second-generation ICS is to be presented publicly as early as Autumn 2014, with a launch date scheduled for 2017.

Development of the first generation also continues unabated. As the power electronics are fully integrated, the BRUSA ICS only comprises two components. The two primary and secondary coil housings already contain all the AC/DC converters as well as the communications and safety equipment for vehicle positioning and foreign-object detection. This means no external wall box or HF cabling is required – an absolute first for inductive charging systems. With the ICS BRUSA has achieved a power-transfer efficiency of over 90 percent, making it almost lossless. Indeed, the CarTec Awards jury was so impressed it named it winner in its category. Currently, BRUSA is working hard on making the ICS ready for mass production, with testing also taking place under everyday conditions as part of a small fleet trial.
