Wireless Charging over the AIR!!!

Recommended Posts

Posted · Original PosterOP

we all have heard the rumour that apple might release a device capable of charging phones over the air, well that might just be possible very soon. it's invented by Energous and this technology had been approved by the FCC. what it does is it uses a radio frequency to transmit to a certain device at a distance using a field transmitter called WattUp which the company claims can charge a device which is equipped with a WattUp receiver. The original article is from tomsguide. here's the link : https://www.tomsguide.com/us/energous-wireless-charging-fcc-approval,news-26302.html

While I like the idea of completely wireless charging I'm sure this is going to be extremely slow and or have several more major problems

#1. Treat others as you would like to be treated.

Even Fast Wireless Charging using 18W adaptor only charges at 10W wirelessly. So the power loss is abundant. More so when it's further away from the source.

And while QCing @18W my phone barely gets warm but while Wirelessly Quick Charging @10W with the QC2.0 Wall Adaptor my phone gets hot to the touch.

It's cool and all but this is definitely have some efficiency issues. They are probably directing the radio waves towards the charger but a lot of those aren't going to be picked up. 

 

If it's good enough to be able to charge faster than your phone battery drains that'd be insane, but I really doubt it. Efficiency concerns are too great, and even then I don't see the thing being portable enough to fit in a phone. If you look at the video that phone case is insanely thicc

With enough density throughout the world, there will be no need for batteries!

True, and since the FCC green flagged the idea then the electrical interference is minimal to the point that other signals are not interrupted. I really hope this company has looked into pacemakers and if there are any issues.

It's only 35% efficient if i'm not mistaken (theoretically without the losses of conventional methods) plus what it takes to make this happen and the interference possible.

I believe we can also "wirelessly charge" popcorn over the air and it pops, makes for quite a delicious treat.

 

Not sure I want my room filled with the same kind of "wireless charging over the air" waves around where I have other liquid based things that electromagnetic waves could agitate to the point of creating a current, like my brain, definitively don't want to turn that into a delicious treat.

Tom's Guide:

Energous is the latest charging-at-a-distance company to throw its hat in the ring, but it has a significant leg up over its competitors: It’s just become the first-ever technology of its kind to get FCC approval.

Quote

“As the first FCC certification for power-at-a-distance wireless charging under Part 18 of the FCC’s rules, this development represents a new era of wireless charging, and opens up a tremendous opportunity for the electronics industry,” Energous announced.

 

Part 18 of the FCC rules (which, incidentally, work wonders if you’re having a bout of insomnia) deal with “Industrial, Scientific and Medical Equipment.” Before selling new technology in the United States that takes advantage of radio frequencies, companies must seek FCC approval and abide by rules concerning operating procedure, interference and restricted radio bands.

Quote

As far as what Energous claims to do, it’s pretty much what it sounds like. The company says it has developed a field transmitter called WattUp, which beams a signal via radio frequency to any device with a WattUp receiver attached. WattUp is platform-agnostic, meaning you could theoretically buy a charger for any phone, regardless of who makes the device. The technology can theoretically charge devices quickly via wireless contact charging (like what we have today), or more slowly just by being in the general vicinity of the WattUp transmitter. Right now, Energous says its transmitter works at distances of up to 3 feet.

I feel like we need to see what's the wavelength and power of this machine before we subject people to a marcospace microwave ._.

Quote

Energous aims to demonstrate its power-at-a-distance technology at CES 2018 next month, so Tom’s Guide will get a chance to see firsthand how it works. Even if the technology works as promised, there’s no indication of how much it might cost — or if smartphone producers will be willing to start incorporating it into their handsets. 

there's your CES 2018 techtuber bingo square

 

EDIT: oh nevermind:

Quote

Tom's Hardware:

The WattUp technology is able to convert electricity into radio waves in the 5.8GHz band and then the receiver that comes built into devices will be able to capture those waves and charge. WattUp-enabled devices will also be able to charge “on contact,” similarly to Qi-enabled devices. This will provide faster and more efficient charging.

Within the first five feet it can push up to 16 W, between five and ten feet it can push 8 W, and from ten through fifteen feet it can push 4 W.

Not sure what the numbers mean, but not sure where to start the maths on this one, lol

(microwave frequency is 2.45GHz for reference)

 

I mean they got federal approval now, but this is one of the times I'd rather exercise caution rather than let some higher-up department say "eh looks good to us"

 

EDIT x2: oh nevermind, I just remembered microwave ovens are usually around 1000W. carry on, enterprise

Image result for good idea doesn't work meme

sounds good actually if my phone like NEVER died.

 

But my parents would probably get triggered if I never put it down also if this could be done to PC's, laptops, and maybe even electric cars in the future that would be awesome

cool concept. it sounds like if you read the article that yes, it will be slow. and only work up to 3 feet. BUT it's a really cool concept/early adopter thing.

 

it will be interesting to see where this tech goes though!

Are you sure that's due to the charger and not due to the wireless pad switching between resonant and inductive mode based on the power provided? Qi supports both, and resonant charging is less efficient but also creates far less heat, so if you have a decent charger it may switch to resonant charging with the lower power charger.

Note older WiFi is also 2.4 GHz. As is Bluetooth, and a lot of relatively modernish wireless communications.

 

And the 5GHz wavelength they're using is used by newer WiFi and LTE cellular signals already.

 

Just because a certain wavelength is used for something scary, doesn't mean that it's dangerous.

 

I'm curious what they mean by "Push" though. Is that output power of the transmitter? Is that received power of the reciever? Is that final power output after it's voltage converted to be able to power the battery? 10-15 feet isn't very far, and even at that range 4W isn't very much power, about what you'd get from plugging into a USB 3.0 port on your computer... If that's not final power going into your battery, then you're not going to be getting much charge from this.
