Now this is a pretty cool concept - “Wireless EV charging”. It’s being touted for buses in Norway. A receiver would have to be installed on the bus, to take up the electromagnetic energy from the retrofitted road. If they can perfect this, you could just drive on certain roads and recharge! https://yocharge.com/news/norways-wireless-ev-charging-roads-a-game-changer/ Norway is making significant strides in sustainable transportation with the installation of its first wireless charging road for electric vehicles (EVs) in Trondheim. This innovative project features a 100-meter segment embedded with copper coils beneath the road surface, allowing electric vehicles to charge while in motion. The pilot program is set to last for one year, during which the system’s performance and efficiency will be rigorously tested. … The primary goal of this pilot project is to determine whether the wireless charging technology can serve as the sole energy source for the electric buses. By allowing buses to charge while driving, the initiativeseeks to reduce carbon emissions and enhance the efficiency of public transport systems. Additionally, the system will be evaluated under Trondheim’s severe winter conditions to assess its resilience and reliability in extreme weather scenarios.
This is a very good idea, but only electric buses that travel the same routes will be able to use it. Why not use trolleybuses then? They are even more environmentally friendly, they do not require batteries that pollute the environment very much during production and disposal.
“Production and Disposal” are key words. Actually batteries are now being repurposed and recycled. How much do we focus on the Production process of ICE vehicles? And after production? Every fill-up is another polluting experience. Extraction is associated with many hazardous wastes, including some which are radioactive. EVs can be powered by renewables. Regarding the trolley, I think the answer is obvious, in that it is relegated to a specific route. This would only be a limitation for the charge-up phase with the wireless.
Here is a list of 10 EVs that support wireless charging: https://www.joinbonnet.com/post/car...-,1.,of advanced wireless charging technology. These are probably more oriented to home charging, where you can park your car over a pad, which then charges your car. But, the charging could come from the road or parking places, etc.
Imagine the amount of copper per mile. And how long it would take to build a highway with copper coils imbedded. Instead of years to finish highway projects it would take decades. Cool idea. Not very practical.
That’s pretty cool. I didn’t know wireless charging was already incorporated into vehicles. I can see this being used by businesses to attract customers. For example, a large grocer could have designated parking spots, and if a customer spends over $100, he would not be charged.
An improvement on the old trolley/tram system. If they set it up right you could feed back into the grid under certain circumstances
Melbourne Aus is ahead of you - we added solar power ;D https://www.premier.vic.gov.au/yarra-trams-install-hundreds-solar-panels-across-network
Really? Ever notice how long it takes to repair/replace overhead poles or wires vs. repair/replace a highway? If this were similar technology we wouldn’t be spending millions of dollars per 100m of road to develop and test the tech. Cool idea. Not very practical.
That’s pretty cool. Loved this —-> “ Catching a tram is already one of the most sustainable ways to get around Melbourne, but these solar panels mean the network will be even more environmentally friendly – reducing the overall network draw on the power grid.”
Seems silly to me. They could certainly just install overhead power lines and aerials to catch them over the same 100m for far less money and with no need to "test" whether it works or not. Maybe they just don't like the French? Seems they have proven tech in service with their TGV.
But bottom line - it is not YOUR pocket this money is coming from as it is not YOUR government doing the experimentation.
As I said before tram systems are really popular in cities still running them just as Trains still have a place. Lols! Though when it comes to trains Aus is still ahead of a lot of the rest of the world with “Road Trains”. They can only operate west of the great diving range and Cities like Townsville have a huge facility on the edge of the city where the trailers are broken up to travel down the coast.
So you get this to work. Then what? Since this type of charging requires power at peak demand times it kind of negates the oft repeated mantra of off peak charging being an advantage to EVs. If this is for public transportation it would be much more economical to develop quick change battery packs. If private vehicles start using this power how do they pay? Each vehicle has software keeping track of how much power is taken from the road and the owner gets a bill? Does traffic re- route to take advantage of this charging if it’s cheaper than a public charger? Or their retail rate at home?
Pathetic as every single argument of mine that presents even a drop of dissonance I've offered here against your church of the Al Gore holy earth bullshit. Are you projecting upon me your own bottom line? Whether or not any of this effects YOUR pocket? There are currently accounted for reserves of 50 years of proven easy oil and gas left. Unlike others, I do not make the absurd argument that it won't run out or worse that it is a matter of economics rather than the finite nature of the resources. So while they play with this gimmick in Trondheim and OXY and others waste Capex on carbon capture plants, time and money is being lost building real and lasting solutions, which to a very large extent we still don't have for the molecular sources in these reserves, but that we most certainly do to create a world wide solar grid while these resources are still available to assist with building it.
What’s popular? Overhead trolley? They are popular because they make economic sense. Under the road wireless charging doesn’t make sense. That is the subject of this thread. I’ve pointed out how DIFFERENT under road wireless charging is compared to overhead trolley lines. You said they are similar. They are not.
Why not wait and see? This will not happen tomorrow. They are not about to dig up major American highways so…….
Again why the angst? This is something happening in another country they are spending the money on it, they are the ones test piloting this idea. https://electreon.com/projects/trondheim-electric-road-project https://www.electricaltechnology.org/2024/08/norway-wireless-charging-road.html
