Well, it does get rid of the "expensive" J1772 "nozzle".
But, the other required parts are expensive, and part must be carried in the car.
Also, not a flexible or sharing-capable system.

How much more would you be willing to pay for wireless inductive charging? It won't be cheap. You also can't plug-share without moving the car. Right now the charging efficiencies are not as good as conductive but I hear they are improving. Personally I do not want to pay more for it but there are probably many who would.

Pay for inductive? Not a penny. I might pay extra to keep the conductive though.

I'd pay $0 for inductive charging. It's highly inefficient and become exponentially more inefficient the further park the car from the optimal location of the charger. What's so hard about plugging the car in? How lazy are people becoming!?

Besides the above, this system relies on a certain driving precision when parking. Its no secret that alot of people would not drive accurate enough to use this, get frustrated and just plug in. If you were precise, it would be very cool!

...but isn't this useful for the folks that are not hardcore EV enthusiast and just similar convenience to the car they are already driving (excluding the gas station stops)? ie. when you pull into your garage it just starts charging or waits until the scheduler tells it to start charging.
In other words, will this help propel EVs to the masses?
In theory, couldn't the device in your garage be like a 3' wide platform and the middle 1' area auto-matically self centers to the optimum position for the most efficient inductive charging? Food for thought about another perspective.

I see little advantage in this at home, plugging in is easy peasy. I do see one big advantage in public spaces. It would cut down on the opportunities for vandalism greatly. But I don't see anyone paying to retrofit existing cars.

It might not. The inductive charger is a gigantic coil of wire (inductor), they will just steal the entire matt and scrap that, probably more copper in that than the existing J-1772 cables.

Or the whole coil mat 3' dia. Get the sweet spot of your car somewhere in the circle and it functions.
Hypothetically the coil would be embedded in the asphalt or solidly encased (since they'd have to survive being driven over). You would need some VERY dedicated criminals to fish those suckers out.mitch672 said:
I don't think it would work that well. At highways speeds you're using, roughly, 20-30 horsepower for most cars. If you go with a really aerodynamic design we can make that 15HP for argument's sake. That's 11kW per vehicle, times thousands of vehicles at any given time. You are easily into the megawatts before you even figure in efficiency problems... with that much inductive loading your power factor is gonna be naught point poop! :lol: Plus I'm pretty sure any magnetic field strong enough to transfer the required power is going to cause a drag on the vehicles.LKK said:
For optimal charging you want a stationary target and a small gap between the coils. I like the idea of automatic alignment which can be easily (but not cheaply) accomplished... imagine putting inductive charging at curbside metered parking spots, and integrating the charge controller with the parking meter. that would be a good system!

The South Koreans are testing such a setup on a test road, Samsung I believe.
Its a popular subject, probably the future of short range battery dependent electric vehicles.

Self-Centering, auto-clamping:
It would be a lot more efficient if the "floor" electro-magnet jumped up off the floor and "stuck" to the matching magnetic poles that are exposed on the car's bottom, drastically reducing the magnetic air-gap.

I would think a linear motor embedded in the highway would be more practical. Then the long range issues would be resolved and the battery size could be reduced to just get you to the next embedded rail segment.

Overhead power might be more pratical. Snap on some removable trolly poles for long trips. The entrance ramp could have a low speed guide to catch the trolley poles and off you go. If you need to pass just disconnect and run off battery. Maybe on very long streatches with no on-ramp there would be a place to reconnect.

Most trains are diesel-electric, I have always wondered why the railroad lines in the US have not been electrified with tramlines in the last 90 years.. apparently diesel is very cheap.

Article in Popular Mechanics about inductive charging on Infiniti's EV in 2014.

Funny you mention Samsung. I bet many of you don't know about http://www.renaultsamsungm.com/" onclick="window.open(this.href);return false;. There was this very old article at http://www.businessweek.com/magazine/content/02_40/b3802159.htm" onclick="window.open(this.href);return false;. At the time when the 5th gen Maxima (00-03) was the latest gen, the 4th gen Maxima was being built by Renault Samsung Motors and sold as the Renault Samsung SM5.Herm said:
