Detroit to receive US first public wireless EV-charging road system

The Motor City will be the site of the nation's first public road capable of wirelessly charging electric vehicles as they drive over the pavement, Michigan state officials announced Tuesday.
The Michigan Department of Transportation (MDOT) awarded a contract to develop and construct a 1-mile stretch of the wireless in-road charging system near downtown Detroit to Israeli-based company Electreon, a developer of wireless charging infrastructure.
Electreon's technology works similarly to how wireless charging devices send power to phones.
Copper coils are installed under the asphalt of a road to transfer energy from the electrical grid to receivers that can be mounted underneath any electric vehicle, in turn, automatically charging the vehicle's battery. The road can juice up vehicles that are in motion or stationery, according to the company

That copper won’t last a weekend in Detroit.

I wonder how much power is lost/wasted with wireless charging?
It's one thing on a small thing, like a phone or an pair of earbuds.
But a car is an entirely different scale. Doesn't that defeat the purpose of an EV, if you make the charging mechanism less efficient?

How much charge can you get driving 1 mile?

Don’t worry. All the wasted radiation is absorbed by our body which will eventually kill us. That’s what the government/elites want anyway.

Will there be a toll?

The government making it sound like it’s so awesome and only to frick people over with more taxes.
“Oh, so you are gonna be paying for gas anymore? Well, we are gonna fix that!”

Ah so this is complete garbage and extremely ineffecient. Wireless phone chargers only use about 50% more electricity than plugging them in.

No thanks, govt.
Keep your shitty electric cars.
Im ok with being the last American to continue using an ICE vehicle.

Oak Ridge National Labs have been doing some really interesting things with wireless charging.

With custom magnetic coils, silicon carbide-based power electronics, and novel controls and shielding technology to handle stray emissions, ORNL scientists have proven that their system can wirelessly charge both a light-duty passenger car across a six-inch airgap and a medium-duty delivery truck across an 11-inch airgap at the 20-kilowatt level at greater than 92% power transfer efficiency — on par with a wired system. Power can even flow in both directions, enabling vehicles to serve as energy storage.
The researchers have successfully demonstrated a 120-kW wireless charging system with 97% efficiency, and are planning to install higher voltage systems, up to 270-kW, on passenger vehicles to meet or exceed the 15-minute charging goal.
The research is supported by the DOE Office of Energy Efficiency and Renewable Energy’s Vehicle Technologies Office. The systems are built and evaluated at the National Transportation Research Center at ORNL, the only DOE-designated user facility focused on performing early-stage research and development in transportation technologies. The medium-duty vehicle wireless charging demonstration was held at the new Grid Research Integration and Deployment Center, or GRID-C, at ORNL, which combines multiple electrification research across the vehicle, buildings, and grid space.
The researchers now have a finish line in sight for a system called dynamic wireless charging in which vehicles are automatically energized while rolling over specially equipped roadways. The researchers will make use of a new, one-of-a-kind test bed at GRID-C to evaluate the dynamic wireless charging system and to support research on how the technology will smoothly integrate into the nation’s power grid.

And early computers filled a room and were less powerful than a smartwatch. This is a first generation demonstration project . The technology will get much better very quickly.

Good luck when the salt and snow trucks tackle that shite. Absolutely obliterates roads.

It no wonder copper prices have gone through the roof. The US (owned by China) government is buying it to bury in the road!
And to make broken and broke arse DETROIT your first place to recieve it? Can anyone in Detroit afford a car that wasn't made before 2007?

I can see the crackheads trying to plug they fomes into the street to charge them and getting hit by a Tesla.

They must have solved the water pipe issues in Flint!

Surely they could use that electricity to slightly heat the road possibly eliminating ice on roads. That’d be a cool by product.

What happens when your wireless charging sensor is always covered in road grime?
