How the wireless charging works

  • Wireless charging also is known as inductive charging or codeless charging.
  • They use an Electromagnetic field to transfer energy between two objects through electromagnetic induction.
  • This is usually done with charging station energy is sent through an inductive coupling to an electrical device which converts that energy to charge the battery or run the device.

Induction charges use an induction coil to create an alternating electromagnetic field within a charging base and a second induction coil in the portable device takes power from the electromagnetic field and convert it back into electric current to charge the battery. However, the two induction coils in proximity combine to form an Electrical Transformer. Greater distances between sender and receiver coils can be achieved in the wireless charging systems using resonant inductive coupling.

Recent improvements

Today’s resonant system includes using immovable transmission coil that is mounted on an elevating platform. They are getting close and the use of other materials for the receiver coil made of silver-plated copper or sometimes aluminium to minimize with and decrease resistance due to the skin effect.

How it is going to change the future

However, we should not be in the dilemma that only mobile phones are wirelessly charged but, the engineers have planned to widespread this idea in all possible fields. for mobile phones, there are some major areas where users require their phones to be charged: at home, at their work desk, at restaurants and while travelling. By pinpointing prime charging environments, companies will now be able to streamline wireless charging technology and allow a more user-friendly experience. As electric cars are at a peak so, the automobile companies are planning to set up the wireless charging stations for cars. These will be situated in all possible public parking areas like a mall, city centres, clubs, etc.

  • The burden of carrying mobile charger is over, no meshup with wires.
  • easy to charge electric cars without plug-in plug-out.

The coming years will also see the expansion of the charging ambit to include a variety of other devices, thereby making the technology more accessible and easier to integrate into everyday life. This integration will be supported by the evolution of wireless charging products from being mere accessories to lifestyle products in themselves, thus creating a defined space for the technology.

The limitations which we are facing in wireless charging now

  • The major problem is the efficiency of such type of charging.

Though, a single Android or iPhone consumes only 1-2kw of electricity per year. But as there is an uncountable number of phones or tablets are being used by people so, the amount of electricity consumed by it also becomes significantly high. Again the electric cars are also increasing the demand of electricity at a very high pace.

But the wireless chargers are only about 60% efficient in comparison to wired chargers. In these conditions, it will increase the demand for electricity to a high extent. Thus, companies are not launching wireless charges everywhere but there is still working to improve its efficiency.
