Fully Charged Tests Dynamic Electric Vehicle Charging – Video

DEC 14 2017 BY MARK KANE 28

Earlier this year, a group of companies in France (including Qualcomm and Renault) built a 100 m test track, and also an EV prototype for wireless dynamic charging.

Qualcomm Renault Wireless Charging RoadThe system output is rated at 20 kW, and works at speeds of up to 120 km/h (75 mph).

According to the Eric Feunteun (Head of Renault’s Electric Vehicles), this particular project is a viable proof-of-concept.

The real challenges starts from there, as dynamic charging need to be feasible in the real world, and the industry would need to figure out how to best align the cars (naturally, autonomous driving would be handy here).

“In a military garrison just outside Paris there is a 100 meter long strip of roadway that has been fitted with induction plates created by Qualcomm. Driving over the plates at up to 110 kph, two Renault Kangoo vans picked up a 20 kW charge. It can be done, it does work, but I suppose the big question is will it ever be installed along hundreds of kilometers of highway.”

20kW is about what it takes to power the vehicle in that speed, so “charging” is a bit of an over-statement.

Or, during the 3 seconds it takes to drive 100m in 120 km/h, about 0.016kWh can be transferred.

So instead of having electric wires overhead like electric trains of old this is basically a wireless electric track. So how does it handle flooding? How much did the 100 meter track cost to build because it does not look cheap, I’m guessing $1-5 million so for a short one lane track of 100 KM it would be $1-5 Billion but I could be wrong and it could be a lot more..

Or much less…

😀

Some talk about $1 million per lane mile in production, but I have seen no evidence that is accurate.

This is just an over-enginnered and economically pointless gimmick!

*over-enginnered

*over-engineered 😀

llol

*LOL 😀

agree – this is a silly concept for roads. Could be useful at places like bus stops or depots so buses could get a charge while sitting there for a bit.

Well, then it’s like the wireless charging plates that Mercedes and others will have.
That better be a hit, as it looks really practical. Keep it in the garage, and some parkingspaces. Always topped up to the level the user want.

I actually think there could be a use for this type of roads – but just part of cities.
Busses, trucks, taxis and other could charge, while waiting for å green light (for example).

For inner city driving, a taxy would never have to charge in a regualt way.. maybe. For some hybrids, it could helt keep the tiny battery charged during city driving.

But it all depends on cost, as this would be handled by the city. No easy way to charge from this. Yes, I know about the prox. sensor with ID registration.. so it is a solution… but. .

Combine this with the elevated EV road from BMW.

Wireless dynamic charging is sexy, but the economics are awful.

The economics are 100x better for wired dynamic charging. Wires are much cheaper than induction plates and, because wired connections deliver higher power, you only need to wire 1 mile out of every 10 or 20.

It’d cost a few months of oil imports for the US to put Honda’s aesthetically pleasing wire-in-guardrail system on our rural interstates and major state highways. Their system works for all vehicles from cars to Semi trucks (which would cost half of Tesla’s Semi and carry more payload).

Even a lowly 100 mile EV could go coast-to-coast without stopping.

We had the on-road power and steering model figured out 50 years ago. They were called slot cars – where many of us first learned about “electric cars”. Let’s bring Aurora back to sort out these 21st century problems.

It is very tough to see how this would be practical in any way. Who is going to pay the enormous price tag to install this? Who is going to pay for the electricity? Who is going maintain it?

We are now struggling to just install and maintain a simple charging network. Building an electrified highway is pie in the sky dreaming at this point.

The money can be found in military defense spending, just imagine the savings from withdrawing US troops from middle east and northern Africa because we won’t need to protect our oil and gas supply.

Good idea.

But if you don’t want to get in trouble with military industry lobbyists you should probably propose to just “print” more money.

You might think I was kidding, but the limitation of money is just virtual. It simply doesn’t exist.

Long time ago GOLD had to be mined to back money. Nowadays what do we mine? Right! It’s all about chains. They are virtual.

We BitCoin Mine!!!!

There are trials taking place here in the UK for this technology. https://www.gov.uk/government/news/off-road-trials-for-electric-highways-technology

So what is the energy efficiency / loss of this? Given 1 kwh input, how much of that makes it into the car’s battery? One thing that seems to be missed in most EV discussions on the environmental benefits is how much electricity (from the source, including any pre-drive conditioning) for every mile driven. Just because it is generally cleaner than gas, it still has environmental impacts. Tesla model S at 33kwh / 100mi is still pretty poor compared to several of the cars that are rated at 25 kwh / 100 mi.

We are struggling to build out an EV charging system because we are at ~1% of sales for EVs. How much did it cost to built the 150 thousand gas stations in the US? There were 202 thousand gas stations in 1994. I bet each one was over $1M each due to the underground tanks and pumps and the prime real estate many are built on, so that is $202 TRILLION in capitol costs. Only 1% of gas stations are owned by oil companies, most are single stores, not chains (Source: The National Association of Convenience Stores). The investment will be there when the need is there, just like it was for gas fuel distribution.
Dynamic charging (or more likely, charging at stop lights in cities and a more efficient wired or wireless solution if the tech develops) will take up a lot less real estate, but will likely entail companies paying counties or states to install their systems on public roads and charge fees directly to drivers.

202 billion, but what’s a few zeros between friends 🙂

Capital costs

I would slow down to get the most out of the charge and piss everyone off.
😛

That would be prudent LOL

People would be glad to get the Kangoo ZE with 20kW cable charge.

SOLAR FREAKIN’ ROADS!!

I don’t think this technology is about the near future of EVs. I see it as being something more like 50 years out. But then again, by that point batteries should be so cheap and energy dense that range with really be a problem. So what would be the point to charge on the move?

I agree with the idea that this makes more sense in parking spaces or garages / driveways. Maybe also at red lights. No real point on the highway.
