100KW wireless EV charging at 96% efficient using polyphase electromag coupling?

(1/7) > >>


Is this legit? What's the catch? had to check it wasn't April fools it seems such a leap forward.Would love to see what you guys think.

The numbers are realistic, the economics are TBD. It's not going to be cheap, but that can come down if it's deployed in scale.


A couple decades ago the efficiency of modern switching power supplies would have looked magic too.

All the resonating energy in the coils will take a lot of expensive litz though, no way around that with magnetics with poor coupling.

PS. I wonder if the stray fields are within legal limits.

Not totally implausible in theory, but how accurately does it need to be aligned ?

What happens if a soda or other metallic trash can rolls into the air gap?
