Much Ado About Nothing?

This sounds like "much ado about nothing". If I'm near enough to the charging pad to charge my phone, I might as well plug in my USB cord and recharge at the end of my meter long leash (power cord).  It gives me more flexibiloity than trying to talk on the phone or surf the web while the phone rests on the charging plate. As a frequent traveler, I see the cluster of people on their phones at the power outlets, I don't see a benefit of having to get even closer to use the recharging plate.

I certainly understand some people would feel that way, DrQuine. But then, when I'd have to compete for precious power outlets at the airport (and there aren't a lot of them around), I do long for wireless charging pad.

I'm with DrQuine. If you can't find a power outlet to plug into, why would one expect "charging pad real estate" be more plentiful?

Everyone has to make a buck, and perhaps this wireless charging will become a big hit. But quite honestly, it's a waste of energy and not exactly must-have.

Hi Bert, the Shakespearian allusion not withstanding, there are many cases that warrant wireless charging, some as Junko mentioned are handy when you are travelling or in places where more clients need charging outlets than are available. Or in cases where you are missing any charging cables!

But I agree with your point on efficiency and further wastage of energy. Efficiency is the key to limit such wastages. Couple of years ago I saw a presentation on Capacitive charging where 83% efficiency was demonstrated over a 6x10mm area at 0.5mm separation.

wouldn't those charging pads need to be plugged in too? I don't really see how this will be much better. It is like pining for a power strip!

 

However, having the convencience to have your phone charge in your car and in your home without having to ever mess with an annoying wire again would be really nice.

It is much ado about nothing, IF you have a nice benign environment.  Make it nasty like the stuff military hardware has to endure, and then an environmentally sealed charging method suddenly looks very attractive from a reliability stand point.  Connectors are the number one failure mode of almost anything electronic. Period.

If you want to see resonant proximity charging on a much larger scale, surf on over to http://www.witricity.com and see power transfer into the low kW range for EV's.  We are currently working with WiTricity on an adaptation of their system for an autonomous military system in a harsh environment. 

As this technology matures, it will become much more prevalent.  Consumers will pay for convenience.  They always have and always will.

Travelling with your charging pad

I don't think people will travel with their charging pad, but they will still travel with their charger, so unless the airport provides the infrastructure (as in pads), I don't see your argument. I see charging pads as mainly a home or work convenience. The difference in cost between an outlet with an extension cord and a pad (that still needs an outlet) is huge. Coupled with the limited number of devices a single pad can support, I'm not sure many places will spend that capital. Except Starbucks ...

Of course, if you talk about the difference in cost between an outlet with an extension cord and a pad, the argument for using wireless charging at home loses. But when your smartphone battery barely lasts for a day, you do sometimes wish if you could "tap it off" -- just in a few minutes -- some place in public so that you can call someone.

Car?

How about in your car? Get in your car, put the phone in its cradle (with inductive charger), and drive. You can ask your phone for the nearest steakhouse, and listen to an mp3 fille, sent to your car stereo over Bluetooth.

Having to plug and unplug in the micro-USB charger every time you get in/out of the car gets very annoying after a while so most people wouldn't bother most of the time.

Indeed, using wireless charging in one's car is a good example.

General Motors is reportedly planning to build the smartphone charging technology into a handful of its automobiles.

GM is an investor of Powermat Technologies (the supporter of PMA standard).

With Powermat integration, some GM 2014 model owners can leave cables at home, and instead, simply place their phone on a Powermat-enhanced surface for a battery boost.

wireless charging to be defacto feature in laptops & cars

One of the biggest challenges in smartphones is battery life. When you are sitting in your car or at your desk, you want a convenient way to charge the phone.  

The technology is early and will only get better (and smarter).

Ubiquitous wireless charging, or at least when you are near your laptop or in your car will add hours to smartphone battery life.

A Ford rep at a CEA event ~2 years ago said car makers are working on console surfaces that double as chargers. We just need a standard!

Operators invovled

One of the things that convinced me that this might take off was cellular operators' interest and their involvement in wireless charging.

With the backing of the cellular operators (who obviously want to know where your phones are placed -- beyond the information your phone's GPS is giving out), this will happen over time. (if no operators are interested, infrastructure buildout is unlikely to happen.)

More importantly, once operators say that this is something they want, handset vendors jump; and chip companies need to supply solutions. And consumers will be gladly to accept. After all, who wants to carry a power cord with your phone?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
