Passenger vehicles sit motionless for something like 90% of the time. Having pads placed in parking spots and loading zones (for large trucks) makes more sense than EV charging lanes on highways. Also, chargers are an easy target for vandals unless they're buried.
The ideal use of wireless charging is mass transport like buses and rail where vehicles/locomotives stop in designated places regularly. It will allow smaller, lighter batteries giving improved efficiency and lower cost. It woul also be useful for local delivery vehicles and taxis that might retun to the depot/rank a number of time in a day
Over head wires at bus stops are cheaper and more efficient.
@@michaelberger6699 only marginally more efficient but you have the additional cost of the gantry and the cost and mechanical maintenance of the pantograph
great for carparks everywhere.
Speaking of EV charge stations, if you have charging stations networked and talking to each other, they could optimize multi vehicle charging prioritisation. These charge stations could then advise drivers in their cars, based on their current charge and vehicle range, where the next charging stations are located along their journey to complete their charge. This could help avoid bottle necks at charging stations and allow vehicles with a lower charge state faster access to the charging station, so they can complete their journey as soon as possible. If that makes sense. Thus if say there are two vehicles with one waiting and the one that's charging has been charged sufficiently, it could limit the charge time for that vehicle and advise it to move on, so that the vehicle behind it in a lower state of charge, can be recharged sooner to the required level to allow it to complete its journey allowing enough range for alternate charge station visits along their route also.
Great invention... but it may have to wait until someone solves the issue of pot holes and utility workers ripping up the roads !
I think what people criticizing this miss is that it’s ok if this doesn’t work out as is. Maybe 10% of it works and it used somewhere else. That’s innovation. If we didn’t allow for waste in innovation we’d all still be dragging around clubs.
Its not the clubs
Waiting at traffic lights would be a good place to get an inductive charge.
they should be replacing traffic lights with round-abouts- that would save more energy as cars use most of their energy in acceleration
how do you pay? the city is not going to pay for everyone to charge their car. i see this as a major problem for any road based wireless charging once you get past the testing phase.
They can't build that on the road. Maintenance means frequent road closure. Busy cities can't afford to do that.
@@scottmcshannon6821 "i see this as a major problem for any road based wireless charging"
Have you never used a modern toll road transaction system? I don't see where a payment problem would exist. The tech and systems that would enable the transactions already exists and I espect could be adapted the wireless charging scenario.
@@PolineChan LOL, public infrastucture services are already located under roads. The highest density of such services under roads are found inside the boundaries of "Busy cities".
Wireless charging is brilliant for mainstream charging. It is so much safer than being plugged in…no need to unplug if you feel like you are in danger..
What is great about wireless is being able to make cars with much smaller more efficient battery packs which avoids the ecological damage of large battery packs. No need to be parked in gridlock just charging as driving.
as long as the charging is free, i dont see how paying for your charging while driving is at all possible.
I've mentioned it on this, as well as other channels that we should never have to exit our vehicle to charge it, especially in public places where safety can be an issue. The only problem I see with in-road charging is that in the United States road repair is a multi-billion dollar business so there is no incentive for contractors to actually make streets and highways to last for more than a few years which is why our infrastructure is in shambles.
🔌🔌As a recently retired Cummins Power Generation Engineer from Mpls the last project I worked on with a consultant out of Boise was for a 500kW wireless test site to charge buses and service vehicles in Oregon. The downside of the project was the utility to support 500kW peak power at specific locations. They ended up paralleling a Tier 4 diesel generator at one location. The same issue occurred with Nxu's 4.5MW chargers in Arizona. They rented portable generators to meet demand at their facility Typically the lack of power from the utility generation facilities is not the issue. Instead, it is the lack of xfmr and wiring at the location where the source is required.🔌🔌
"500kW wireless test site"
So it would be fair to say is was a proof of concept project, not a production ready facility? Yes/No?
@@BrentonSmythesfieldsaye I retired before I saw the final results. It was for the City of Portland. I do not recall the wireless vendor but I did meet them in San Diego.
@@Carl_in_AZ Ok fair enough. Sounds like an interesting project. Take care and hope you are enjoying retuirement!
So roll the coal to power the wireless charging?
I'll give Portland credit for improving their local air quality, unlike Phoenix AZ which has gone from the best place to live for respiratory illnesses to the 5th most polluted city in the USA. Today Phoenix issued another pollution warning due to NOx, and PM, not CO2. That makes eight warnings for MTD. When Portland Utility updates their xfmr in four years at that charging site they planned to use the generator as an emergency standby genset. Tier 4 gensets cost twice the price as T2 gensets.
Recharge on highways like in F-Zero?
500kW+ charging enables wireless charging is a game changer. say bye bye to wires.
And conectors Nac Gbt, or J1772 any car could charged anywhere😮
Here is an idea - could you make wireless charged lanes you could almost do a bus based train system within and between cities using self driving technology.
For the large trucking industry this will be huge.
I'm dubious about putting them in roads, but these speeds could revolutionize commercial charging stations. They would look more like drive-thrus or toll booths than gas pumps, with no need to leave the vehicle. In fact, these could be incorporated into drive-thrus--order a charge with your meal. Or into convenience store parking spaces. Another layer of profit for the business, without failure-prone moving parts or above-ground components.
This could definitely work in areas with high traffic congestion. The payment system would be easy to implement, similar to toll roads that automatically charge the user.
Sounds impractical for roadways but fine for dedicated parking spaces. You have to realize that a huge many megawatt backbone would be required for multiple cars being charged at the same time in stopped traffic. You also have to consider the people having problems with high current radiation, like they are considering cellphones. Practical charging requires high radiating AC currents at frequencies in the 50kHz to 1 MHz range. You would also be lucky to get >75% efficiency. We use wires for a reason since they are 95-98% efficient.
"You would also be lucky to get >75% efficiency. We use wires for a reason since they are 95-98% efficient."
Apparently those statements ares inaccurate according to WiTricity. See the page at there Web site titled
"Wired vs wireless charging efficiency for EVs: A comparison"
Wed, Feb 23, 2022"
Who is going to PAY for the infra needed to charge on the move? Probably the road owners. Which is the local municipality in most cases. So the cost will have to come from the tax payer. Meaning even ICE drivers will co-pay for infra like this. Of which they have NO benefit.
Yes ICE drivers do benefit by helping to lower breathing of noxious exhaust gases.
Oh I don’t know maybe the same companies that people pay to charge their EV’s now? No municipalities have ever paid Tesla to build superchargers.
Until they drive electric
You don't need wireless roads everywhere just in places where cars have to stop for a while. Parking lots and signal controlled intersections would be a good start. Loading docs would be another good place for large trucks. However, the amount metal coils needed would not be an efficient use of the material unless it was also the rebar.
I think that the most likely outcome for charging electric vehicles is that the batteries will be large enough, and the charging will be fast enough, that will only "fuel up" once a week, unless we're travelling a long distance.
Always the best content from Sam 👍
*Your videos are always very informative and entertaining, many Thanks for that 😊*
I think stationary inductive charging should already be more common, but furthermore I think we will get mobile inductive charging eventually, especially with electric car racing.
Put that with 800 billion dollar subs Sam, best of luck paying it off.
Wireless charging will always lag behind cable charging. I think it would be useful as an addition, but will not replace conventional wired charging.
I personally thing these will be best placed in parking spaces in service stations and in cities. At home it will be easier to use wire due to cost of the technology.
Sounds futuristic to me😆
Wow! The important thing is the charging needs to be faster than one drives. Or if most roads do not have wireless charging, then the faster the better, on the roads that do.
Wireless charging could be for electric fright trains at all the stops and slow bends.
Look into Kempower's Megawatt Charging System seeking to be part of the solution to the challenges of electrification of heavy-duty vehicles to meet the EU's decarbonization goals. Trucks and large vehicles are currently responsible for around 25% of the CO2 emissions generated by road transport in the EU. They are part of a network being built across Europe by Volvo and Mercedes Daimler Trucks for their EV heavy-duty truck solutions.
You're thinking is very narrow. I could see this being offered in parking lots where employees Park their cars, popular shopping centers, Etc. Why can't someone just pull over a parking spot that's going to charge your vehicle while they're there if they stick their debit card in a meter device next to the parking spot?
Would be useful for buses at start/end of route. Like at airports bus arrives at 1:45 charges for 15~30mins then leaves & repeat cycle.
At that speed if you go to a rest stop to go to the bathroom or grab a coffee - you would come out to a charged vehicle. I wouldn’t need it for my car as I do home charging about once a weeek
I think any solution that can reduce battery capacities is interesting. I dont think fast dc charging will be replaced by wireless because if you drive to a place specifically to charge your ev in rhe quickest way possible , you wil prefer to take a few seconds to plug it and make sure you have the best charging speed, efficiency, and cost. But wireless charging is interesting for ev owners wirh no garage using street parking. building a charger at every parking space require a big amount of construction and means a lot of sidewalk real easte taken by chargers and cables. whereas installing wireless chargers under the pavement could be done anywhere there is street parking with no impact on the sidewalks. streets get redone on a regular basis so it could be done at the same time as scheduled maintenance. level 2 is sufficient. you could just park, the car is charged and parking fee + charging can be applied automatically.
We use to run electric buses from overhead wires in the 1900s. This is more efficient than batteries. More train freight powered by renewables is a better solution.
Less friction as well.
The future "would have been" wireless charging before 1. Battery tech allowed 5 minute charging. 2. 90%+ personal transport will be robotaxi, car ownership not needed.
Nice
I could see this on bus routes where there are set routes and stops or for delivery vehicles with specific delivery points. I'm not sure about continuous highways, too expensive and complicated.
Charging technology charging forward by leaps and bounds becoming less and less concern.
Wireless charging is something that would be very useful in a home garage. I like the concept. Unfortunately, if you follow the stock market then you know that Ideanomics/Wave(IDEX) is not doing well in terms of stock pricing. It has undergone a 1:125 reverse split ( 8/25/23) and the stock is still under $1/share. I intended to invest in the company based on its potential but with a reverse split particularly of that magnitude, I decides against it. At the time prior to the split, it appeared the IDEX was the best of the Inductive(Wireless) charging companies I knew something about. Witricity might be the best one now but I still like IDEX for some unknown reason. I still might throw a few dollars into the IDEX slot machine at the Wall Street Casino. If IDEX goes belly up, then I will only be out the equivalent of a few cups of Starbucks coffees.
They will put this on the 4 lane highways, with a one mile charging lane for every 20 miles.
With wireless charging you don't have to worry about too short cables, too heavy cables, ports being on the wrong side and public safety etc.
The quickest way to fry your batteries.
There is an interesting business opportunity here putting wireless chargers at junctions, traffic lights, car park spaces etc and taking micropayments from cars even if they only sit over you for a few seconds...
Thank you
You're welcome
Fast charging regularly has typically degraded the battery significantly.
I wonder what has been done to offset or compensate for this issue.
It doesn't do me a lot of good charging twice as fast if my battery lasts 1/2 as long as a result.
Newer battery tech may eliminate the issue, but we don't know yet.
Some possible applications might include weigh stations wait lines, rest stops at truck stops and on highway.
Commercial (service company) installations are worth considering for this tech.
Cost.
quite a good example… for eat sleep repeat…. maybe 🎉
A lot of safety issues here. Defibrillators, pacemakers and insulin pumps are all adversely affected by magnetic fields. I get that a vehicle can become a faraday cage. But what about people walking on the street or next to it on a sidewalk. Then there is weather. How do these systems deal with standing water or snow ❄️?
Who is going to pay for all this new technology? and is the electricity going to be free?.
With multi user's all charging at the same time it will be a nightmare sorting out who owes what.
Wireless charging is the missing component for fully autonomous vehicles. For some time trucks will need humans to manage the loading so while they are sat there they can be plugged in. At home too you can just plug it in. It's robotaxis operating all day with no interaction with human assistants/owners and only customers that need it most. Having them at taxi ranks where they sit for a while makes most sense for that. There and parking lots for private cars so that the infrastructure isn't taking up space.
Sounds great! We just need a Nuclear Power Station in every town to supply the electricity.
Or lots of renewable energy with large grid level storage...
For 500kw per charge?
Nice battery, I'll climb it one day
Make wireless charging toll roads need roads designed for heavier EV'S need to upgrade power grid first
Roads are already designed to accomodate heavy haulage trucks and commercial vehicles.
@BrentonSmythesfieldsaye not all roads. Also, won't these haulage trucks and other commercial vehicles be heavier if they are electric? I guess they could haul less and make more trips for the same job
@@marvenlunn6086 Are you speculating or do you know that actual comparable weights? Unless you can show evidence that there is a compative impact, you are just promoting speculation.
People keep banging on about EV weight, yet the most popular current ICE vehicles are generally heavier than EVs, where I live anyway. The roads will be just fine. Plus as EV's continue to evolve they will become lighter anyway. Batteries, just as one example, with become more energy dense meaning the packs can be smaller for a comparative range. But the EV is also redefining vehicle manufacturing techniques and philosophy and it is still early days in their development. Changes and progress are coming at an ever accelerating rate at this time.
People really do speculate heavily about things they are unfamiliar with. When in reality there are clever people involved in all this vocationally, that understand the challenges and will resolve challenges when and where they may exist.
@BrentonSmythesfieldsaye EV'S are about 20% heavier than a comparable ICE vehicle technology is going to improve, but when and what about the power grid you hear about places having blackouts all the time
@@marvenlunn6086 "EV'S are about 20% heavier than a comparable ICE vehicle" - Says who?
"the power grid you hear about places having blackouts all the time" - Name one that has been caused specifically by EV charging!
My car phone charger is wireless. I almost never need to plug it in
Hydrogen is the most abundant element in the universe, but most industrial hydrogen comes from processing natural gas
Is there a concern in regards to pedestrians being close to these wireless chargers?
Would hopefully require a vehicle to activate the charger.
@@OTPulse Was more thinking along the lines of electricity radiation as in being under over head power lines, though many say that is not a hazard.
@christopherj2231 That's been a thing for a long time, and it's proven to be a hazard. Lots of farm animals grazing near high voltage lines have far higher cancer rates than usual. That's why junctions for electricity distribution are almost always away from towns.
Your concerns are completely valid but reasonably easy to avoid with shielding and not having them active when not in use.
@@OTPulse OK thanks for that.
I would rather use Nio's battery swap stations. It is much simpler and let Nio handle the maintenance of 100% robotic swap system!
I can see this charger being used in parking areas, e.g. charging stations, overnight parking or residential garages.
Trying to embed these chargers into active roads, where the construction/materials vary region to region and country by country, and the surface weaning requires resurfacing every decade or so... no. Too much complexity.
Imagine if it is China, the media would say wireless charging is unsafe. The main thing is how to get you pay. It is probably not going to be cheap. Anything in US is not cheap.
Hello Mr Viking, any thoughts on what is happening in Europe:
"Electric car sales plummeted across Europe last month as demand dried up despite the EU’s push to ban petrol and diesel vehicles by the middle of the next decade."
Hello Mr Jamie-ck6js, any thoughts on what is happening around the world:
"Global EV sales up 12% in March, down 9% in Europe, Rho Motion says"
9% down still means an increase in the number of EVs on the road. If in January they sell 100 EVs, then in March they only sell 91 EVs that means there are now 191 EVs on the road. People are also seeing EV prices dropping and are waiting for new models and better value.
With the EU aren't banning petrol and diesel vehicles, they are banning the sale of NEW petrol and diesel vehicles. There will be a very strong second hand market. People will be able to buy cars up to the end of 2034, and second hand from 2035. So ICEs will still be around until 2050.
One month does not make a trend my friend!
Thanks for the information 👍
Any time!
Hey Viking the Fire Station argument you made is just not a good one, yes firefighters have a higher risk of cancer but it’s not because of the “exhaust in the fire station” because fire stations have to have exhaust filtration systems that automatically connect to the exhaust pipes when the trucks pull in the station. NFPA 1500: Standard on Fire Department Occupational Safety, Health, and Wellness Program specifies that fire departments contain all vehicle exhaust emissions to a level of no less than 100 percent of effective capture.Apr 19, 2019
What is the effect of rapid charging on the battery.
Easy it’s called battery degradation .
New phones have fast wireless charging 🤔
👍
It doesn't make sense to have predictably gridlocked streets!!! It doesn't make sense for private cars to be the primary mode of urban transportation.
……. Like they’re not now?
@@sparkysho-ze7nm If we want a better future, it shouldn't be by relying on the our current failures.
EVs are great for those who truly need to drive. We shouldn't be incorporating ridiculously expensive solutions into our public spaces to encourage those who don't truly need them. We should be (re)building better cities that rely much less on private cars.
Technology courtesy of Nikola Tesla, the "Master of Lightning"!
the best us of this would be in parking lots, loading docks. Bus Stops.

Am I correct in seeing Electric racing cars using this technology on the race track?
I'm would like to see the fossil fuel industry introduce wireless charging for gasoline. LoL
Wireless is always less efficient than wired charging, so an extra nuclear plant may be required even in the less populous countries. 10% extra charging loss in Finland (5.5 million inhabitants) would mean 4.5 TWh of new electricity production needed just to cover it, if the traffic is fully electric and wirelessly charged. That is about ⅔ of a small NPP's or ⅓ of a big NPP's yearly production. Not to mention extra copper coil, etc. that has to be built into the vehicles and driven around, too.
So, no.
Wrong. It's more efficient than a wire.
@@chrisedwards8365 Maybe in some other universe.
Wonderful. But maybe the money is better invested in removing traffic bottlenecks
You mean like the line up at Fast Food and Coffee spots like Tim Hortons? How about the long lines at charger locations?🤔
As electric energy costs decline, the issue of charging efficiency becomes less important
Even way more electromagnetic fields everywhere? No thanks.
You were obviously good at physics, most people don't know there is no way to protect it.
Depending on the battery configuration, they could wireless charge even faster than 15 minutes or charge at the same rate using less power, by using a quadruple line charge controller for a 4 battery configuration layout. Say 4 x 20 kW batteries. Obviously the charge controller would need to be robust enough, however you could use 4 coils and 4 charge controllers for 4 batteries to maximise charging speeds and efficiency. Thus the 4 batteries are wirelessly charging in parallel. Super fast !!! Super safe !!! Each battery pack gets you say 70 miles of range, thus totalling 280 miles of range. Because you can charge super fast, range becomes less important. A battery management system would optimise the use of the batteries and charging regime based on an optimisation algorithm, linked to the driving requirements and charging patterns.
By distributing the charging load across multiple batteries, you can potentially mitigate the effects of internal resistance and maintain higher charging speeds compared to charging a single 80 kW battery. This is because the overall charging process is distributed among multiple batteries, allowing each battery to charge at its optimal rate and minimizing the impact of internal resistance on the overall charging efficiency.
Thus a 4 battery pack configuration could make 5 minute charging to 80% well within reach.
Most drivers on most trips don't drive more than say an average of 40 miles per day. Thus one of the four 20kW battery packs could comfortably cover that distance and thus be run down from 80% ( 56 miles ) to 10% ( 7 miles ) approx.. SOC ( state of charge) being the optimal charge range for certain common battery chemistries. i.e. assuming a range of 70 miles per battery pack. This usage pattern allows drivers to make the most efficient use of the battery capacity while minimizing stress on the battery cells. All this, whilst retaining super fast charging in a safer and more efficient way than charging one 80 kW battery in the same amount of time.
Could you not have, say, 8 batteries, with 4 installed for normal weekday trips (at the center of the car) & adding 4 for longer trips (2 on each side of the 4 central packs)?
Not sure about viability of 8 battery packs. Some manufacturers have used varied chemistries in multiple battery packs for the scenario you suggested. I would say if you can have two batteries packs, then you could have more than two, however there would be a point of diminishing returns. Much would depend on driving and charging habits and requirements. Obviously they make products based on average Joe usage patterns. The average Joe for example in the USA drives 40 miles per day.
10% of 500kw is not a small loss. Thats 50kw could almost power 3 house instead of being lost. Never mind that it make no sense along roads and highways as the infrastructure cost would be crazy. Suitable for bus stops maybe but an over head power direct connection would be better.
Where is the tipping point??🤔
You can't be seriously suggesting this will be viable.
Only on Fantasy Island.
Dont doubt the ingenuity of mankind my friend. This concept goes back to Nikola Tesla and we are just now beginning to understand how to harness magnet fields which are electrical. We still dont understand gravity yet which is also electro-magnetic...
@@jaaklucas1329 Here in the states, it's a money issue for many cities. Never enough funds to even fill potholes. California, where I still live, is in a $70 billion hole.
So would all EVs need to be scrapped for new ones that have the induction charging system?
Trucks probably need fast charging less than most, as they are required to rest the drivers, so could be just recharging normally.
Are there any dangers of induced current on people animals or just some conductive material dropped over these areas?
Of course the biggest problem will be getting charged for the power, rather than just recharging from the solar on one's own roof.
Firemen might have a lower life expectancy because it's a relatively dangerous job.
Ya it's as usual an idiotic argument from ornamental haircut boy. If it were a problem a simple detachable vent hose is all that would be needed.
People are afraid of their 1kW microwave leaking, yet they will sit in a 500 kW field every day? Cancer alley.

It doesn’t matter if it exists if the grid can’t support it. The grid can’t support the fast chargers already. Do you not know that? Wow
i'm sure, in cold snowy climates, those snow plows will just rip them apart over time
They probably won't be built in snowy areas. Not everything should be built everywhere.
Wouldn’t the snow and ice melt with the heat generated from the transfer of energy? No snow plow needed over these roads…you’re problem is solved.
Me not so much
Why have the cost of two systems when just a plug in battery works. You still need a long range battery for off charging paths. Also why pay for electricity off a corporation at a higher rate.

The Largest producer of plastics in Australia has just been put into administration and will shut down, the major reason, the high cost of energy in OZ, so Australia now has the highest electricity prices in the world and as this plastics company found out unaffordable local gas supplies, and yet Viking will get on his pulpit and carry on about cheap renewable energy prices, there is something missing between Climate Alarmist ears and we all know what is between our two ears.
Any health risks to that? Like standing next to a microwave oven?
Yes i wonder on the electrical field as well
99% sure it would be Off if no vehicle is above it. And cars would only activate it if they are built with the ability to use it and the required amount of shielding.
It was raining heavily in Dubai. Even cars swim
High efficiency induction is real, it works in Europe. It pays for itself, per bus, savings of 1M$+ in fuel costs and maintenance. The charging pad is sealed. Perfect application in 2/3 or more of USA ( less cold).
Mate, the technology in China is supported by other countries. They don't own all the technologies. Remember, the chicken tax was put on because of US patent infringements.
