One thing that’s a bit misleading in this video, a majority of wireless phone chargers run off a 5V USB connection still, not the AC from the wall. So they still include all the inefficiencies of normal charging with an extra DC to AC and AC to DC conversion. If they could use the 50Hz AC power from the wall directly to the coil on the phone you could actually charge more efficient than using the USB cable. Texas Instruments have been working on 50Hz AC chargers but the end device would have to support it.

Audi developed the Audi wireless charger, this system has an efficiency of 90 % www.audi.com/en/innovation/futuredrive/wireless_charging.html This system uses a mechanic device, which lifts the coil plate up until it has 1 cm gap between the coil plate and the car. Conventional cable chargers have more than 90 % efficiency, but they also don't have 100 %.

@simonm14476 жыл бұрын
That's true, the System with a cable has an efficiency of about 90 %, means from 10 kWh charged from the grid you have around 9 kWh in the battery to use. The wireless charger will cut another 10 %. But that's still a very high efficiency, compared to ICE cars. The engine of a gasoline car for example has an efficiency of around 35 % at the best, but in many situations the engine runs not in the most efficient rpm, and with lot of power available and only little power really used (for example powerful engine, but low speed) the efficiency decreases to 20 % or even less. Diesels are better in this point, but no combustion engine ever reached more than 50 % efficiency, while bigger electric motors can reach more than 90 %. The motor of the Model 3 for example (a synchronous motor with permanent magnets) has one of the best efficiencies ever reached.
@nikoladd6 жыл бұрын
+Simon Maier .. well no 90% efficient transmission does not include the signal preparation or received power management. So it's at best 90% to the transmitter, then 90% to the receiver then multiple frequency rectification let's be optimistic and say 90% again... so it's 0.9^3= 0.73% of the power reaching the battery charger. So even in your sci-fi version it's losing at least a quarter of the power. It's a big amount of power when it comes to cars. My point was not that EV's are bad, quite the contrary. My point was that a workable wireless for cars has a lot of problems to solve.

I advocate for QI as a baseline . Its fast enough to charge any phone and most tablets overnight at a 1-2 amp rate . Yall are getting 8 H of sleep right? provided you can get a day out of a charge then who cares If at night in your 8H of sleep your phone takes 3H vs 1.5 h... does that matter. VS Weigh in the wear you put on your USB jack . Is it cost effective to replace a $800 phone over a loss in % eff in charge rate. what is the envro damage of a useless bricked phone due to a ripped plug Vs the extra power needed to make up for driving a 90% eff QI charger. does any one weigh this as math. ???? The power to refine the silicon to make the chips. the power to machine or Injection mold a case . power to reflow the solder on to a PCB that takes power to cut ! Now lets talk disposal of the now useless phone and its effect on a landfill and last but not least the biz cost If I have to take time to buy a new phone and then take a day to Xfer the apps and get * settled in * how much is your time worth lets say the loss of lossy QI charge means over a year you pay $16 more in power.

Actually, the problem with "most" of these systems is that they are uni-directional, and short ranged. There is one startup company, though it hasn't yet shipped a final product, which uses 3 coils, set up to provide multi-directional charging, and, presumably, a bit greater range. You need only be "near" the so called "motherbox", or its smaller portable version, to get your phone to charge, presumably. So, yeah, with it, assuming it really works as advertised, you can use your phone, while it charges, instead of having to lay the thing down some place. But, in something like a car, this is less of an issue, since.. you shouldn't bloody well be using it that way in the first place (and is technically illegal in many places), and most cars now allow wireless syncing for hands free operation.

I have a wireless charger integrated in my bedside lamp, so I just put it down before I go to sleep and then simply pick it up in the morning, no hassle at all - no wires, plugging and unplugging from the wall. I honestly don't even know where my standard charger is right now, I haven't used it in a long time.

We were really close to a huge disaster. The equipment they would have needed to handle the situation didn't even exists (and it don't know if it even exists today). It will take decades to clean up the mess, and they have to invent solutions afterward, to handle it. Yet, experts were telling us that they knew what they were doing. Obviously, they weren't. 4th generation have many times more fissile material than Fukushima. Safe? coolant would be sodium, which explode when in contact of water.... Come on.... This industry is almost 70 years old, and it still doesn't know how to handle its waste. For some time they were dumping radioactive barrels at the bottom of the ocean! I don't believe thoses experts anymore. Maybe some other nuclear technologies could be safe by design but it would mean almost starting R&D from 0 , would take decades and cost huge amount of money. Even thorium that we hear some time, like Funny Memes talk about, is far from being proven, and has it's own downside. About aesthetics of wind turbines, I find it pretty pleasing.

Even if we only went with the 40% efficient charging system, and even if only half the extra grid energy were to come from clean sources, and even if none of the vehicles had a solar panel roof, an inductively charged road network would still yield a net reduction in emissions Bonuses: - what emissions continued to happen would do so in large, remote, static facilities that can have massive filters, as opposed to gridlock smogs in urban areas with That Guy spewing horrific black fumes - less need for road transit of fuel to petrol stations - less physical wear & tear on ports Drawbacks: - what are we going to make all these batteries out of, where are we going to get the raw materials from, what are we going to do with the spent units - market pressure to enforce proprietary elements that fragment the market.

The idea thing here would be for a feedback mechanism in the inductive charger for cars. Car pulls up, signal sent to charger to start charging, Charge pad starts charging, when battery is full, Wireless signal sent back to charge pad to shut off. This would be the least load on the utility network in my book.

That efficient wireless charging station looked like it raised up real close to the vehicle to get that quality coupling, am I the only one wondering why they didn't just add contact pads and charge that way? Simpler and more efficient.

3:58 If you construct your own transmission coil you can wind the coils around the entire room by placing the wires behind the baseboard. Obviously, you need to know what you are doing or else you will electrocute yourself/start a fire. But if the operation works, you can charge the device anywhere in the room. In fact, the size of the magnetic field will allow you to receive partial charge from outside the room and from adjacent floors.

That was exactly what Tesla did in a couple of his experiments. He adapted small coils to power incandescent bulbs in his laboratory but wrapped coils around the perimeter. He understood from the beginning that it was a near-field technology, so his vision (at least for this type of power transfer) was that every home would have coils built in to light the room with no need to string wires anywhere else :]

Not true, at the edge of the room the phone will only barely charge due to the loss of flux and near the pole you would just fry the internals of your phone due to the great amount off flux needed to keep the entire room in the magnetic field, there is a reason why transformators use laminated cores instead of just air

Nice video as always, BUT! There's one major thing that's bugging me as i was very intrested in the problem of efficiency. You did not say what the efficiency of a traditional charger is! Without a reference or comparison numbers are completely meaningless. I don't know how bad it is compared to what we have now, and that is the relevant question. Cheers!
@gnautist6 жыл бұрын
The efficiency loss measured in that study was only that of the wireless transmission device, not how well it charged off of that. In this case the efficiency of a "traditional charger" (copper touching copper) would be basically 100% comparatively. The efficiency of how well the charge circuit say on the phone accepts power from either device would be the same.

@nipunagunarathne48826 жыл бұрын
Woo 991 the loss in the wire is negligible. Around 1%. Which means 99% efficiency. I did the calculations. Besides. That's a biased way to do the comparison. It gives the wrong idea. It's like saying "car A does more miles per gallon than car B" but it turns out you have to run car A with the AC on because it gets hotter inside than car B which makes the mpg gain null and void.

I just don't understand why I would ever use such a technology. With my smartphone plugged into my PC with a reasonably long USB-cable I can charge and operate it at the same time. It's like magic! And it is fully charged in under an hour. Now with electric vehicles I might be able to understand the benefits. Although, not really. Any kind of efficiency loss means longer charging time and higher electricity bills. And this is quite significant for operating an electric vehicle. It is no great inconvenience to just plug it in. Now, I understand that in public places chargers can easily get damaged or some funny dude just unplugs your car. But I just don't think one would regularly charge one's car in a public parking spot.

Once upon a time phone batteries struggled to last all day, so you would buy a spare that you could swap out in seconds. Then phones got better battery technology and lower power usage, you could now go a week between charges, so you didn't need a spare battery. Then smart phones came along and we've go backward ever since :) BTW, I don't want high frequency magnetic fields all that close to me, wouldn't buy a car that used it.

@Pete8564 жыл бұрын
@@Rebius How do you think wireless chargers work? Wireless (or induction) requires AC to generate alternating field lines in the primary which is picked up in the secondary coil, the faster this alternates the more electricity that can be generated in a given area. The battery pack is charged from the secondary coil which picks up the alternating magnetic flux which causes electrons to flow, generating AC. This AC is then converted to DC using a rectifier and feed into the battery.

The root problem of all electrical devises is that the electricity has to be generated from somewhere and transmitted through long distances. Unless every house has its own solar panels system that can generate enough power for daily usage and charges EV, the push to EV will collapse the current grid.

Forget about the wider issue of adding more grid capacity. The biggest problem for adoption of wireless charging for cars is that it doubles the cost of charging your car. With increasingly fast rapid charging that’s a trade off that becomes less and less attractive. For phones, I imagine that wireless charging is slower than charging by cable. Personally I would always prefer a fast charging USB port to be available instead of a wireless pad. Of course there is the slight issue of having to carry a cable with you, but I’d much prefer phone manufacturers to standardise on a single type of usb power connector, then cafes could provide us with a usb cable instead of a usb socket.
