Wireless Power Consortium (WPC) finds new applications in the kitchen at CES 2015

While visiting with John Perzow (Who writes for Planet Analog along with WPC guest members), VP of the WPC, we spoke about McDonalds adding 600 Qi wireless charging spots in the UK (“Want fries with that charge?”); wireless charging in automotive; and other applications, but not much was made of a small corner of the WPC booth which had an application I had not expected, but which intrigued me–Kitchen appliances powered wirelessly via Qi in the self-tuned resonant mode. The WPC and Philips are working together in this effort which should bring products to the market very soon.

If you look closely at the butcher-block counter top you can see a ring of small circular dowels identifying where the appliance needs to be placed in the self-tuned resonant field.

The appliance power turns on when the appliance is switched on. Internal circuitry by the appliance manufacturer will activate the 1,200 W (We will see 2,000 W in the future) self-tuned resonant field installed under the counter top as well as a communication link between the appliance and the under-counter electronics. The appliance and the under-counter tuned resonant circuit will both be turned off when the appliance switch is turned to the OFF position or the appliance is removed from the field. The WPC standards will enable the proliferation of appliance manufacturers around the world just as it has done for smart phones, tablets and PCs.

Look for more innovations in the future using this amazing technology like being integrated into furniture and more.

    It is very good to see the 1200W of wirelss power transfer. I thought just mobiles and other potable small devices are being charged using wireless power trasfer.

     

    The only challange after seeing this I feel is the distance of power transfer. Whatever applications and products available right now are having a very small transmission distance. If I can charge my mobile phone through out the room from a single wireless power transmitter then also it would be very good appriciable range.

    Wireless charging is getting popular for any type electronic tool needing the primary and/or auxiliary power, including vehicle. Efficiency for power transfer might be questioned from customer and engineer.

    @Vishal—When I was at CES last week in Las Vegas—Witricity showed a floor mat that goes on your garage floor with wireless power transfer to charge your car when you drive over it. They are extending the charge distances using magnetic resonance. I am sure that soon we will see larger distances. 

     

    Did you ever see what Nikola Tesla did early in the 1900's with wireless power transfer?

    Steve, you may be right about wireless charging point. If am not wrong, Nokia was first one that introduced wireless charging for mobiles. I think the same technology can be used in wireless charging for all kind of appliances. If McDonalds introduces such charging system, is it free or paid one?

    Vishal, 1200W is high power, what about its field effect? It can disperse some power to the surrounding; which can create electro static forces.

    Steve, thanks for the updation. You mean the power is passing through the floor matt from plug point to the wireless contact point. What is the charging capacity and how long it will take to charge an automobile/EV car. No doubt that like free wifi, coffee shops may start wireless charging points to customers very soon.

    ->No doubt that like free wifi, coffee shops may start wireless charging points to customer very soon.

    Each business place might require the wireless charging station to attract more customers. Implementing the wireless charging station might not be easy in the existing location and building structure, as considering the power grid and distribution at each place.

    @MyAnalog: Yes and I guess some have already started it but my only worry is that with the number of users being exceeded, the speed will decrease

  9. dassa.an

    @MyAnalog: Well IMO, I feel it's a very risky thing to do. You do need to take risks but in a very mitigated way

    @DaeJ: Also the cost a big factor. Any idea about the costing that will have to be allocated for these projects ?

    I am taken aback by this development. Kitchen counter! Thats a place where you expected wireless charging the least. But more I think of this, the more sense it makes.

    When i account on wireless charging one of the challenge i see apart from lower efficiency is its increased resistive heating.

  13. chirshadblog
    January 15, 2015

    @samicksha: Yes there are some pitfalls but I'm not sure whether we can eliminate the heat totally. We should try to mitigate the heat as much as possible

    Very important concern. I was also talking about the efficiency of the wireless charging. If it is wasting more energy than it is transferring, then what is the point of using wireless charging.

    Also if there is a signinficant radiation from the wireless charging point, the health concerns are also to be considered properly.

    Steve, Agreed by your point. The wireless power transfer had been exercised years back also. So, it is not the new thing, but modifying it and making it suitable for the commercial and consumer application is the big challange. And that too wihtout adversely affecting efficiency and human health.

     

    I like the idea of charging mat which is very sensible use for charging vehicles when they are idle in the parking. The adverse effects can be of a less concern in that application.

     

    And ofcourse thanks for the pointer, I will look in more detail for the megnetic resonance to increase the distance.

    Resistive Heating aka Joule Heating. Oh yes, thats an undesired byproduct. But is that more pronounced in wireless than wired? Or am I missing something here?

    Daej, it's all a part of business and they need to attract more customers with attractive offerings. They will find some mechanism for implementing it; but my concern is how they can get ROI for such new offerings.

    Dassa, you are talking about which application; wifi or wireless charging mode.

    “Well IMO, I feel it's a very risky thing to do. You do need to take risks but in a very mitigated way”

    Dassan, in all business risks are there, but some way they will manage it on trial run basis.

    Vishal, radiation and health hazards are important than wasting energy at this point of time. Better efficiency can attain later on by implementing new methods or technology. But its atmost important to protect from, all sorts of radiation and health hazards.

    You are right. And specially when most wifes are working in the kitchen for hours(perticular case of blog), it is very important to have safe instrument when it is being used very frequently in day to day life.

    Vishal, yes, sometimes disaster from electric shock is unpredictable. So security first and then convenience.

    Any new impimentation will have a initial cost involve into it. As a business, it should look into more long term stratergy. 

    If concept is good and make sense, organization could invest on it with an initial cost and could gradually catch up with profits.

    Not always. A business always has to see what the market wants before finalizing whether a project that “makes sense” should be brought out into the open or not.

    Building kitchen friendly things is another step towards a smarter future. Another kind of unforeseen danger lies in the kitchen, the case of exploding gas cylinders. In the south east Asian countries gas is supplied to the homes using cylinders, however there have been reports of them bursting and killing people in their range. How to solve this problem?

    @yalanand: I agree this is a common problem but it isn't very difficult to solve it. All you need is a network of multiple sensors installed within the kitchen that are able to detect smoke and a series of sprinklers which get automated and spray water. You may go one step ahead and link this system to an alarm system which also alerts the local fire authorities about it.

    I wonder if wireless charging is really a useful feature in the kitchen or is it something that comes about as a luxury with no real use. Given the fact that most kitchen appliances have to be used a particular spot, I don't see how wireless charging will aid here.

    Well wireless charging does away with cable management and makes the kitchen appear cleaner.

    Yes, that has happended in my country. But that is due to different reasons, mostly due to heating issue. Lack of awareness of how to safely operate the cylinder is the reason behind this. People are incresingly being aware of it now and that type of incidents have reduced happening now.

     

    If the wireless power transfer scattered energy heats the cylinder, due to its RF heating mechanism, then it would surely be a disaster applience in the kitchen.
