The New Tesla Wireless Charger is AMAZING

Tesla made Apple's Air Power before Apple could make Apples Air Power! All thanks to a 3rd party company named Free Power of course. Today we get to take apart Tesla's Wireless charging platform. A pretty fancy little device that cost 300 dollars. BUT... with good reason. There are 30 coils of copper inside this thing and it looks AMAZING!

@@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.

Freepower already sold a similar device through NOMAD but it was called Base Station Pro over there. The old one could only charge two devices at a time and there was a long history of firmware updates as they were getting the bugs out. I previously had the NOMAD one but it occasionally would not charge my phone. (Which was a bit upsetting to wake up with an uncharged phone.) I now either charge wired or with an Apple certified Magsafe pad to be sure I always have my phone ready when I wake up.

Hey, electronics engineers, any reason these were with circular coils rather than squares (to maximize area)? Is it problematic with the magnetic field it creates, or just harder to control?

@ventilate4267 Жыл бұрын

Because then you wouldn't be able to call it a coil /s

@quinndonnelly Жыл бұрын

It’s more a question of efficiency, you want the flow of current to match the direction of the coil on the phone’s coil; squares would have little current matching up directionally, it would still charge, just much slower

@Muerte_S Жыл бұрын

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 Жыл бұрын

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 Жыл бұрын

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.

Once you plug the charger into the wall, its probably going to sit there on a desk, bench, or nightstand untouched. So you wouldn't have to replace the cable like you would doing wired charging. Kind of like how a nightstand light doesn't need to cord replaced.

It was exactly as I anticipated (finally I'm feeling that I'm an engineer) well to explain the concept in simple terms since they're using all those coils as sensors they can determine the exact position of the phone as mentioned in the video, after that it'll be just like a normal wireless charger so it doesn't really dissipate much heat What apple tried I guess was increasing the electromagnetic field which obviously would cause a lot of thermal and efficiency problems
