The wire is enameled which means it has a very thin, transparent coating so there is no risk of wires touching each other. So the glue is probably just there to make sure everything stays in place and maybe add some separation for heat dissipation

The coils isn't the thing that gets warm, the high frequency switching circuitry does.

[@moonasha]

@@DOGMA1138 the coils are an inductive load, basically a big resistor. Of course they get warm.

[@DOGMA1138]

@@moonasha Take a thermal camera to a Qi charger and see for yourself, the coil barely gets above ambient, the resonant circuit on the other and gets quite toasty as you are looking at switching frequencies of up to about 200 kHz and at voltages of up to 200v. This is also why you have the TIM on the switching circuitry and nothing on the coils. Heck the coils in this one are glued with glue that pretty much dissolves at around 50-60c....

[@tjl2836]

​@@moonasha Inductive loads (and capacitive loads) do not generate heat, only resistive loads do. Inductive loads oppose changes in current by storing excess energy in a magnetic field, whereas resistive will always oppose current regardless and will dissipate that current as heat. Since inductors store energy as a magnetic field, that energy can be harvested by another nearby conductive object like a second coil. This is how wireless charging works to a basic degree. If any heat is genenated from inductance it is from the natural resistance of the copper coil wires which is unavoidable unless you use a superconductor.

[@hannesschwan6284]

@@DOGMA1138it depends on the topology and control strategy.. typically the resistance of the coils limits the efficiency when you are in areas above 90%, below that the efficiency is commonly influenced by poor switching conditions of the FETs, which are a result from the variable load due to the variable magnetic coupling.. you are right that the glue is an indicator for low temperature Operation of the coils (which either indicates brilliant optimisation of the coils, or a poor overall efficiency with most losses in the converter as you said) What I was asking myself, the shielding can’t be seen in the video, so either there’s is no or it’s hidden between the coils and the converter PCB?

The flux generated by a coil is proportional to the Area and the cost of the coil is proportional to the perimeter. The circle shape has a better perimeter per unit area compared to the square shape

[@dennisbrannvalls1fan964]

There are a variety of reasons but the main ones are efficiency and ease of manufacturing. A circular coil produces a magnetic field that is evenly/uniformly distributed in all directions, making it more efficient at transferring power to a device placed anywhere on the charging pad. A square coil would produce a magnetic field that is stronger near the corners and weaker along the edges. This non-uniform field distribution would lead to less efficient power transfer and result in a slower charging process or require the user to carefully position the device on the pad to ensure it is charging.

[@froyogumball]

not an EE, but I think it has to do with the even distribution of the field produced by a circular coil vs a square would produce uneven fields concentrated in the corners. The receivers would also be circular so squares wouldn’t match up as much.

apple also had an array of IC chips on the device that interacted with the thing it was charging to play the animation also they needed different coils due to the apple watch charging system being proprietaty. any company can lay them out in a grid array like this its been done before airpower was a concept

[@nobro_i_ate_u]

Yeah, imagine all of these coils, this must waste a lot of energy

[@grahamb7947]

Thanks for watching, Tim Cook 😂😂 Nice start to the video. A $300 pricetag is pretty crazy though, even with the coils embedded into it coming out to $10 each. One of major points when making something, is to ask whether the price is accessible. For most people, definitely not, considering most won't even spend more than that on their smartphones and opt for a Samsung Galaxy A-series device or other low-mid spec android. Having a charger priced equally to the actual thing you want to charge? Yeah, I don't see the success. Even pricing it at 1/3 to 1/4 of the price of a high end smartphone makes me step back and think. It's not only here where I have that issue either, but also for example with Apple themselves, and the exorbitent prices they charge for iPad folio keyboards these days. $200-300 for a case for an ipad that costs the same amount - it's like WHY??? The iPad was supposed to be the budget option, but then you make an accessory which makes it anything but budget friendly. I just don't see this being profitable for Tesla right now with that said. Especially given that Elon surely paid hundreds of millions on R&D for this, including creating the tooling required to actually mass-produce it. Maybe I'll be surprised though and it becomes huge.

[@MarianKeller]

There is no money to be made in the low-cost market for western brands. For what happens if you try to compete there, look at all the failed German consumer electronics companies. Appealing to people just wanting to buy the cheapest shit is just a race down a bottomless pit.

[@_tsagas_]

What makes you think you are Tesla's target audience?

[@neofaktion]

Dude Hundreds of millions on R&D for this? A separate company with the technology made it for them. It is purely meant as a novelty and collectors item. Also, most low to mid spec android phones do not have wireless charging. You are just not in the target audience. Also, did it ever occur to you that companies need to make money on things? Even if the coils were 10 dollar each, they are free to just charge whatever price they want so that they can turn a profit. The price of an entire car isnt the sum of all the parts together ..

[@grahamb7947]

@@neofaktion dude. Apple couldn’t figure it out with their trillions of dollars. Also, tooling manufacturing machines isn’t anywhere close to as cheap as you think it is. Companies commonly offset those costs by making it as accessible as possible to as many people as possible. And you’re way off the mark by saying I’m not the target audience. It’s hardly a designer item, nor is it limited edition being made purely for the obscenely rich. If it were, it’d be priced much higher than $300. Tesla are targeting anyone who has a wireless capable device. Maybe not with this specific iteration but at the very least as a working prototype to gauge the market

[@neofaktion]

@@grahamb7947 Apple couldn't figure it out due to them wanting to combine their proprietary Apple Watch charging tech, and regular Qi wireless. If they were targeting anyone who has a wireless capable device, then they would price it accordingly. In this case, they simply collaborated with a company who already had the tech.

Thanks for the tear down. 65watts is not going poof when a device is partially using it though. It would only draw 65w when maximum devices are connected. This can be measured using a plugin energy meter.

[@C-TYOIM6940]

Just to explain since there is a lot of misinformation in the video, but especially in the comments: 1-This charger is not revolutionary (I explain below) 2-Apple will not release a similar charger (I explain below) 3-Tesla did not do what Apple cannot do (I explain below) -No, pizza is not a vegetable (I won’t explain.) 1: this charger is nothing revolutionary, you still cannot place a smartphone (or other device with wireless charging) anywhere on the plate. Like Xiaomi and Huawei having released a charger 2/3/4 years earlier, there are areas of non-capture). 2/3: Apple will not release a similar charger since Apple wanted a charger allowing complete and effective recharging on all the recharging plate while being completely transparent. Which is not the case here for 3 reasons. 1, the charger has no coils at the top, and not enough coils on the sides (there are definitely some ineffective areas on the edges for small devices). 2, the charger has a notch at the bottom to place the smartphone correctly, like all other chargers of this type, this makes the placement of the phone on the charger absolutely not transparent (this is also the main reason why Apple has not released a charger). And above all, having a notch allows the user to constantly orient the smartphone in the right direction. Apple did not want this, since in their charger prototype there could be 6 to 8 coils constantly activated per device (in order to make the charge 100% effective on all surfaces regardless of the placement and orientation of the phone), which is absolutely not the case here (the placement is constantly vertical, with 2 coils maximum lit). 3, to make the charge effective at 100% everywhere regardless of the direction and positioning of the smartphone, it would be necessary to add a layer of coils, and allow the activation of 6 to 8 coils at the same time, which would create heat impossible to control. contain without active cooling.
