Wireless Charging - How It Works and How Beneficial It Is?

Wireless Charging - How It Works and How Beneficial It Is?


         Yeah!! Now, it is possible to charge your tele-communicating gizmos and even other electronic devices without cables. Wireless charging is now a days latest piece of technology and spreading in the world of electronics at a lightning speed.

        The new technology arrived in market which provides wireless charging or rather inductive charging in technical terms. To be more specific, the wireless charging basically works on the fundamentals of electro-magnetic field to transfer the type of energy between the two devices. There are two coils one in the pad of the charger and other in the electronic device which is required to be charged.

How It Works


Initially the induction device uses an induction coil which releases the electro-magnetic field.  The other induction coil is in the device which is to be charged. It receives the electromagnetic field and through the phenomenon of the inductive coupling, that electromagnetic field is converted into electric current and the device is charged then. This becomes very technical as far as the technology hidden behind this type of charging and the fundamentals of science is concerned.

Major Advantages


Wireless Charging is very safe. No wires means No fear of electric shock. Further, this technology is used in medical devices, which is highly advantageous over the wires which are needed to be penetrated through the skin in case of several treatments. No infection can occur as there are no wires. Metal wires gets corroded sometimes, charging wirelessly does not have any issue regarding the corrosion. In the matter of convenience also, this charging provide convenient options as the user need not to attach his device to a cord rather he just need to keep the device near an induction coil and the work is done.


Major Disadvantages


In this fast and furious world, this induction charging seems to be slow. As it is wireless, the electromagnetic field is not direction specific which provides slow charging. Further, in the case of efficiency, wireless charging is lagging behind. For the people who are strictly against the global warming, can’t use this kind of charging as it wastes lot of heat and provides less charging as it spreads open field. Some users find this type of charging inconvenient because one need to put the device near the charging device and cannot even move the device in necessity. As far as the dollars and pounds are concerned, you need some more of them to get the pleasure of this type of charging.

Applications


This type of charging, as it is safe, recently used in the field of mobile phones, medical science instruments, radios in early days, cars manufactured by different companies such as Toyota and in other large machines. In the recent field of mobile phones, there is a Qi Standard and several companies adopted this Qi Standard in their recent inventions. The phones like Samsung Galaxy S4, HTC Droid, Nokia Lumia 1020 and Lumia 820, Nexus 4 series launched by Google and several other devices comes with the Qi standard which supports all kinds of wireless charging.

Future Scope


In short and simple term, wireless charging is good and all I can say is, wireless charging is the future of the chargeable devices but it needs some more modifications in the technology to make it faster and even more efficient to run with the ongoing pace of this technoworld.
