Wireless Office - Bachmann

How the system works?


A battery and a receiving / transmitting unit for the inductive energy transfer were integrated into the roll container. The battery storage is charged at the socket (optionally inductive). The DC voltage network can be supplied wireless or by cable through the roll container.



Project Targets

Next generation of desks without any visible connections - „Clean Desk“

Higher flexibility of the desk


Inductive power transmission with medium power (>100W) in the area of protective low voltage leads to high currents

Providing a stabilized voltage for the desks DC voltage network 


Very compact power transmission system (150mm x 150mm x 40mm)

Representable air gaps up to 20mm

Transferable power <150W
