How wireless charging works and what is the technology behind it


You might have heard about the launch of latest smartphones like Nokia Lumia 920 in the market. The latest smartphones use the wireless charging technology for charging the battery. This is a new avatar of old electrical theory that existed years ago. In this article, I shall discuss about the nature of wireless charging, how it works and its latest developments. Please read on.

What is Wireless charging


Wireless charging is called inductive charging as it uses the principle that electricity is induced from another electrical field or magnetic field of another object, if the electrical / magnetic fields are disturbed or cut. In this technology, a charging station is used for battery charging. Electricity is used for creating an electromagnetic field by using an induction coil in the charging station. There is also a secondary induction coil which transfers the electromagnetic field in to electrical energy for charging battery. This is the principle followed in most of the electrical transformers.

How Wireless charging works


Nowadays, your smartphone with Wireless charging mechanism comes with a charging pad or charging cover. Actually these charging pad or cover contains lots of smaller coils which will emit electromagnetic radiation when connected with electricity. The smaller coils are designed such that the alternate coils are charged with your alternate form of current viz., Alternate Current. These alternate charging of minute coils and corresponding emission of electromagnetic radiation poses different electromagnetic fields at different points of time.

Your smartphone also contains few minute but stationary coils and when your smartphone is placed on the charging pads or covers, the coil in your smartphone actually acts as if cutting the electromagnetic fields created at various points by your charging pad or cover. Thus cutting of electromagnetic field by the coils of your smartphone induces current or electricity. The smaller amount of electricity thus created is transmitted to the battery of your smartphone, keeping it live. These mini doses of electricity actually accumulates in the battery of your smartphone and therefore, the battery gets fully charged depending on the time interval at which these charging pads or covers are being used for charging.

Future uses of Wireless charging


There is electromagnetic radiation everywhere. If we have any power to see these electromagnetic radiations with our naked eyes, then we would be astonished to see the complex network of electromagnetic radiations around us. This Wireless charging mechanism is surely going to transform the way in which many of the portable electronic items work in our world. We can see the simplest form of electromagnetic radiation in the radio receivers, where the electromagnetic wave signals transmitted by a radio station and reflected by the ionosphere of the atmosphere, is received in a flawless manner. Therefore, this particular mechanism has started its journey by way of Wireless charging of your smartphone and sooner or later we may see many astonishing and astounding wonderful inventions of electronic items that harvests the powers of Wireless charging or Induction charging.

In the 18th century it was an imaginary thought that whether the wireless charging will be possible or not. But in 20th century this come true and the wireless charging works on the principle of Inductive - Electromagnetic Field.

There can be more than one device can be charge with the help of wireless charger. It eliminate the need of the wired charges and problem that many people are facing.

In wired charges Multi-pin the user use to insert the pin of specific device with specific model. Sometimes the pin is broken down and damage which result in no alternate solution for users. So with the help of the wireless charger , this need have been fulfill.
