Wireless power

eta­tro­nix spe­cia­li­zes in wire­less power trans­mis­si­on (WPT) and its inte­gra­ti­on into power manage­ment sys­tems.

“Inductive power trans­mis­si­on is based on a simp­le phy­si­cal princip­le. However, it requi­res excel­lent engi­neers to deve­lop a mar­ket­a­ble pro­duct.”

We take over the deve­lo­p­ment of elec­tro­nics, inclu­ding soft­ware and mecha­ni­cal com­pon­ents, and deli­ver tes­ted and packa­ged pro­ducts to our cus­to­mers. Lean decision-making, modern pro­ject manage­ment along with effi­ci­ent pro­ces­ses and work­flows help us to com­ple­te pro­jects on sche­du­le and in com­pli­an­ce with qua­li­ty and cost requi­re­ments.


Cost opti­miz­a­ti­on begins with defi­ning the requi­re­ments and designing the sys­tem, whe­re we work clo­se­ly with our cus­to­mers to ensu­re an opti­mum out­co­me.

Working clo­se­ly with our cus­to­mers from the start enab­les us to deve­lop wire­less power sup­ply or char­ging sys­tems that can hold their own in com­pa­ri­son to con­ven­tio­nal sys­tems, par­ti­cu­lar­ly in terms of effi­ci­en­cy and cost.


Thanks to spe­cial­ly adap­ted reso­nant tanks and effi­ci­ent power elec­tro­nics, our WPT sys­tems often achie­ve effi­ci­en­ci­es of more than 95%.

data transmission

eta­tro­nix WPT sys­tems offer inte­gra­ted, bidi­rec­tio­n­al data trans­mis­si­on at a trans­fer rate of up to 100Mbit/s for trans­mis­si­on of app­li­ca­ti­on data

Worldwide licenses

The dif­fe­rent regu­la­to­ry frame­works for wire­less power trans­mis­si­on around the world are con­fu­sing and the requi­re­ments for spe­ci­fic coun­tries need to be given due con­si­de­ra­ti­on right from the very begin­ning of deve­lo­p­ment to ensu­re a seam­less mar­ket intro­duc­tion.

eta­tro­nix has the necessa­ry exper­ti­se, works clo­se­ly with cer­ti­fi­ca­ti­on part­ners, and takes care of the world­wi­de licen­sing pro­ces­ses for our cus­to­mers.


eta­tro­nix sys­tems pro­vi­de a num­ber of inter­faces that can be used for data trans­mis­si­on, con­fi­gu­ra­ti­on and updates, inclu­ding WiFi, CAN, I2C, USB, SMBus and PMBus.


eta­tro­nix offers its cus­to­mers inter­ope­ra­ble solu­ti­ons based on the stan­dards deve­lo­ped by the Wireless Power Consortium (Link: wirelesspowerconsortium.com). Qi — mobi­le com­pu­ting is the stan­dard for smart­pho­nes and con­su­mer elec­tro­nics in the 5 to 15W ran­ge. Using a WPT sys­tem in the Medium Power Standard (30 to 65W) can be an attrac­ti­ve opti­on for power tools, vacu­um robots, robo­tic mowers, dro­nes and other app­li­ca­ti­ons. At pre­sent, the con­sor­ti­um is working on the Ki Cordless Kitchen Standard for kit­chen app­li­an­ces up to 2.2kW. This covers app­li­an­ces such as toas­ters, cof­fee machi­nes, water/rice coo­kers, mixers, and such like.

High control dynamics

A paten­ted pro­cess ensu­res rapid con­trol of out­put varia­bles, i.e. the­re is no need for a down­stream DC/DC con­ver­ter in most cases, which redu­ces instal­la­ti­on space, weight and cos­ts, and incre­a­ses electri­cal effi­ci­en­cy.

ATEX certification

We were the first manu­fac­tu­rer ever to achie­ve ATEX cer­ti­fi­ca­ti­on for a WPT solu­ti­on.

Integrated battery management system

One of the strengths of the eta­tro­nix bat­te­ry manage­ment sys­tem is its sui­ta­bi­li­ty for almost every cell che­mi­stry and cell con­fi­gu­ra­ti­on. In addi­ti­on to con­trol­ling and moni­to­ring the char­ging pro­cess, the sys­tem keeps track of the bat­te­ry sta­tus (SoC, SoH) at all times and ensu­res safe ope­ra­ti­on.
