How does the induction charging in Nokia Lumia

For years, speaking batteries are charging by induction, transferring energy from one device to a charger without using cables. It is a technology that is increasingly mature and has challenged the manufacturers of these devices smartphones to include this type of technology.
The equipment that we saw coming up with this innovation were the Nokia Lumia 920 and Nokia Lumia 820. These devices actually innovated to make available to users with a wireless charging where you just need a recharge base. Nokia showed that it is simple and explains the technology involved.


All we need is to put one of these Nokias a wireless charging plate Nokia or a Nokia Wireless Fatboy pad or a dock .
But there is more equipment presented recently at the keynote , along with the Lumia and Windows Phone 8, one such example is the JBL PowerUp .

But ultimately what is wireless charging?

It's a rather simplistic, but that should be explained so that increasingly, is a native function and not an extra. As always had, there is the traditional method, in which a wire leads to the electricity mains device, for the purpose of charging.
This wireless technology carries electricity from one point to another without resorting to the wire, energy is conducted through the air. Basically, compared to smartphones, which means is that our phone will be loaded without having to connect it to a wire or a plug.

Inductive Energy

While all this sounds very simple, especially for us non-specialists, the truth behind much technology is involved. The diagram below shows the basic principles of inductive power transmission.

A transmitter coil is positioned at the bottom (L1) and receiving coil (L2) is situated at the top and these coils are incorporated into different electrical devices. L1 would be a Nokia devices for loading, a wireless card loading and L2 would be the Nokia Lumia 920, for example.
An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiving coil. This voltage is then used to load the device using this magnetic field.
Nokia has adopted the standard Qi (pronounced chi ) in their wireless charging. Qi was created by the Wireless Power Consortium and is used by over 100 different companies around the world, and is the only interface adopted globally. Moreover, because it is used globally, we users have the ability to charge devices at different locations, even around the world. Using this technology would be a method that will use all brands.
For this whole Nokia already has partnerships with some establishments "type" as a coffee service or mass, which will allow users of the future Nokia Lumia 920 and Nokia Lumia 820 can use a simple table, available on those sites to load their smartphones. These are just some examples of what we may see more assiduously among us, business partners that allow this shipment using this technology.
Soon we will have multiple devices that abandon the traditional load from smartphones to electric shavers, everything will soon be charging by induction.
Nokia wants to be a leader in offering this technology and now provides a cushion Fatboy, a dock and a wireless charging plate, wanting to do this type of loading pattern.

Then will appear the combined, where a speaker, as shown JBL, a desk, a project or any other device input or output can be used for charging and for other purposes together, the equipment may be employed but loading.


This is, in our view, the function that makes the difference. We can imagine our car in an area destined to "land" the smartphone and he is being charged while operating to transmit a call by bluetooth using the sound of the vehicle.
Having this technology at home, where we always put our phone when we got home, without having to seek the charger. Have in our workplaces that place where the phone is kept, but the charge.
All this is possible now, Nokia has brought to reality by the user of the future. Now besides asking the key Wireless, will ask where is the table where you can charge your smartphone. [Via Nokia Conversations ]
