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

in reply to PonyOfWar • • •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

in reply to saigot • • •This is a wrong take. It needs to be normal to leave your car plugged into a charger.
Cars take too long to charge for us to consider it reasonable for someone to stand next to their car waiting while it charges (even worse - as I write this the temperature is -17C, but even when things are nice). We need to expect that people will be doing something else while charging and only come out sometime latter to move their car. If someone is at work they can't leave work until lunch time. If someone is at the symphony/theater it is impolite to leave when the car is done charging as it disturbs everyone else.
Of course if your car just as enough range to get back home so you don't need to charge for normal trips that is better. However when someone needs a charger it should be considered normal to stay there for 6 hours, there needs to be enough to handle that. (obviously people making a road trip will disconnect as soon as the car is charged so they can continue on, but if

in reply to bluGill • • •Why not just drive home on gas, you said it yourself it's a rare case you go downtown. It's not acceptable to leave a vehicle parked in front of a gas pump, this is fundamentally no different. You're inconveniencing people because you don't want to drive on gas once in a while.

in reply to Concetta • • •There are reasonable limits. Let's say his car takes 30 minutes. Is 31 minutes total connection time acceptable? I think everyone would say yes. How about 35 minutes? 45? An hour?
Where people draw the line is going to vary. I agree with the premise that you shouldn't have to wait by your car to charge, whether it's 30 minutes or 2 hours. That is wasted time, and drastically reduces the attraction of having an EV. For myself, having to wait an extra 15 minutes isn't too bad, and extra half hour or more is probably too much. I think context also really matters. If I'm parking at a station in a garage where most of the users are there for work, I expect to be there for at least 2 hours, possibly 4 (and would pick a charger I could use most of the time). At a mall, where people are in and out, if I was going to be there much more than 30 minutes I would probably plan to be back at my car to move it when it was charged. Especially since most of the chargers I've seen bill based on connection time and not electricity used.

in reply to saigot • • •Why does the cars need to move?
Just build car charging coils into every parking spot, then have a computer keep track of what car arrived at what time, and give them an hour each of full charging sequentially.
Example
Car 1 parks in space A and starts charging, car 2 arrives shortly after and parks in space D, the computer logs the VIN and timestamp, placing it first in the queue. 30 min later car 3 arrives and parks in space B, the computer logs the VIN and time stamp, placing it second in the queue. Then car 2 leaves space D, the computer logs it and removes it from the queue, making car 3 first in line, then car 2 arrives back in space D, and is placed second in the queue since it left earlier.
No need to move tonnes of metal and batteries, just switching the power, a cheap and fair way to extend the number of charging spaces, while not overloading the circuit and ensuring that everyone gets a fair timeslot, all without having to risk dammage while moving the cars.

in reply to SaveTheTuaHawk • • •Simple, since the system knows the VIN of every car, it knows who to send the bill to.
You could even have a Terminal at the entrence of the facility for those who want to prepay.

in reply to cmnybo • • •90 cents per charge? And no cable that you discover after you’ve pulled up to the charger is broken?
Seems like this will pay for itself in short order at fast charging stations.
cmnybo
in reply to Em Adespoton • • •That would require the car to have a fast charger on board. That's a lot of extra cost and weight.
It would be much better to have a robotic connector that automatically connects to the car when you pull up to the charger.
Pyr
in reply to PonyOfWar • • •I wonder about the costs though.
If you can just have a plate on the ground instead of a interface and cord perhaps it might be useful in parking lots, where EVs can just park and charge while they shop without having the have the space requirements of the charging infrastructure.
