Wireless EV charging hits 90% efficiency in Swiss real-world trials (interestingengineering.com)

Bonus video of Swiss-German in the wild included. If you think German sounds harsh, you'll love the Zuerich dialect. At least it's all done in sing-song fashion, as is called for.

A real-world trial by scientists in Switzerland has demonstrated that wireless EV charging can achieve up to 90 percent efficiency compared with conventional cable-based systems, while offering far greater convenience.

Supported by the Swiss Federal Office of Energy and the cantons of Zurich and Aargau, the project, called INLADE, was carried out by researchers from Empa in collaboration with the electric utility Eniwa AG.

Through this first-of-its-kind initiative, the team tested wireless inductive charging under real-life conditions in Switzerland. They are certain that what has long been routine for phones and electric toothbrushes could soon become a reality for EVs.

“The aim was to test the existing technology in everyday use, clarify technical and regulatory issues and demonstrate its potential for the energy transition,” Mathias Huber, from Empa’s Chemical Energy Carriers and Vehicle Systems lab, said.

That does sound like an interesting scenario. I guess the big challenge here will be getting the actual self driving implemented and approved across manufacturers. Also, if we had that, couldn't the car just as easily connect to a physical docking port of some sort? But I guess a wireless charging pad would be more friendly to various car shapes.

Of course it'll be awhile before anything like that, this is just one engineering problem solved. But self driving within a confined space like a parking lot (especially a parking lot that doesn't normally allow humans) is a lot easier to solve than the general case. I think you'd see adoption happen first with fleets of cars or buses, before it would become common place for just regular stuff.

Physical connections are really rough, they require millimeter precision, Tesla has been trying to do this for ages
