Inductive Charging with ICI [ˈiːzi]

Charging the ICI way!

In wireless power transfer (WPT), electrical energy is transmitted inductively, means without contact, from a stationary magnet coil to a receiver coil for example in a vehicle. Depending on the transmission power energy storage can be charged quickly in electrically powered vehicles during a parking process. Such charging systems are used where environmental conditions do not allow contacting or classic plug-in system are too cumbersome.

Thanks to the latest SiC switching technology and special coil design, Stercom's 22kW Inductive Charge Inverter (ICI) achieves a transmission efficiency of up to 94% even with large air gaps up to 20cm. Stercom WPT complies with the standard DIN / IEC / TS 61980-3
