etaLINK (inductive wireless charging system)

GFFT Rank: 14,03


Wiferion GmbH (formerly Blue Inductive until 2019)


Product Profile

Wiferion produces a contactless wireless charging system (etaLINK) that transfers electrical energy through a high frequency magnetic field (induction) over an air gap to charge electrical vehicles in the intralogistics industry autonomously. The etaLINK system is available in a 3 kW and 12 kW version, can be modular combined and is with an 93 % efficiency comparable to the best traditional cable charging systems.
The contactless charging systems allows self-driving robots and AGVs as well as industrial trucks (manual or autonomous) a fully automated charging. The pads can charge any kind of batteries (e.g. lead-acid, lithium-ion) with the same charging station as it can provide different voltages (15-120 Volt). This means, that different industrial e-vehicles can use the same charging systems. The e-vehicles can be charge with high power during short breaks without any human intervention and therefore eliminate costly charging breaks. By creating an “In-Process-Charging” the fleet availability will be increased and the battery size will be reduced which is an additional costs reduction. The charging starts in less than 1 second with full power and turns on automatically whenever a vehicle arrives. As there is no physical contact between the components the system has no wear and tear and requires no maintenance. The system allows easy integration into the factory or warehouse - even outside due to IP 69 - without any large infrastructure work and can therefore rearranged if the layout changes. The cloud-based data collecting software etaHUB with CAN-connectivity gathers all relevant information to manage the fleets.
