Anyone come across a wireless power transfer equipment for EV charging? Just saw reference to such in Article 625 part IV., new in 2017 NEC

What would that be? A coil you park over?

Yep. But what happens when your kitty decides to nap in that spot while charging?

Apparently, yes from reading the section. But I'm wondering what they were smoking (again) because three or four years later it hasn't become mainstream and coming up with requirements for something that didn't exist is kind of ridiculous.

It's not ridiculous at all. It tends to prevent numerous different & incompatible designs from evolving independently.
This has been looked at for a while. The biggest problem with it is that you need to be really close to be at all efficient and aside from efficiency you won’t be able to charge as fast. So it makes sense in your garage overnight but it would be terrible for road trips at public charging stations. Think about the difference between charging on 10 A and 50 A. On 50 A you can get to 50% charge in 30 minutes? On wireless it would take close to 3 hours.

Sure. Look at how closely the design of that Plugless system in that video follows 625.
It should also come without saying that it's not the NECs business to interfere with emerging technology and free trade. I wouldn't be surprised if they weren't biased by a particular manufacturer to favor the product they were developing.

I just saw a video that showed they've used this wireless technology in France and it buried in road surface and it was maintaining and charging vehicles at full speed moving down the roadway. Guess sort of an induction 3rd rail. Next step for toll roads?

Don't we already have wireless toll-road billing?
