BRUSA doubles power density of inductive charging system

BRUSA Elektronik AG has doubled the power density of its wireless ICS inductive charging system for plug-in vehicles (earlier post) to 7.2 kW while retaining the same compact footprint.

BRUSA said the increase in power density was due to a special technology it patented. 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—i.e.,. no external wall box or HF cabling is required.

BRUSA’s ICS achieves a power-transfer efficiency of more than 90%. BRUSA is readying the ICS for mass production, with testing also taking place under everyday conditions as part of a small fleet trial.



A good early improvement from BRUSA. Could be enough for domestic usages, for most PHEVs and short range BEVs. Future improved wireless charger generations will handle 50+ Kw.
