Wireless Charging Explained: What is Wireless Charging?

Hey guys! Today I will explain to you about wireless charging technology. I have covered almost all the important terminology related to wireless charging.


What is Wireless Charging?

Wireless charging (also known as Inductive charging) is the type of charging a battery which uses an electromagnetic field to transfer energy between two objects using electromagnetic induction, the production of electricity across a magnetic field. 

It is usually done with a charging station. Energy is distributed through an associate inductive coupling to associate device, which may then use that energy to charge batteries or run the device. 

It is the technology that permits smartphone wireless charging, such as the Qi wireless charging standard.

Induction chargers use an associate coil to make associate alternating magnetic attraction field from among a charging base, and a second induction coil in the portable device takes power from the electromagnetic field and converts it into current to charge the battery. 

The two induction coils in proximity mix to create an associate electrical device. 

Greater distances between sender and receiver coils will be achieved once the inductive charging system uses resonant inductive coupling.

Wireless Charging is predicated on the Inductive Charging technology. For wireless charging to occur, 2 parts should be present:

1.Transmitter — This is often conjointly referred to as a sanding pad or charging mat.

2. Receiver — Could be a case attached or built within the device to be charged.

The process of charging is achieved through the transfer of energy/power produced by passing an electrical current through two coils to create an electromagnetic field.

The created electromagnetic field comes in contact with the magnetic plate on the receiver generates an electrical current which is then converted to direct current (DC) and in turn charges the receiving device’s battery through inductive coupling.

Many flagship smartphones being free over the years by high original instrumentation makers (OEMs) have the wireless technology constitutional, 
however, older devices may need a special case or adapter to be attached to them to charge wirelessly through inductive charging.

Advantages & Disadvantages of Wireless Charging:-

Advantages of Wireless Charging:

Protected connections – No corrosion once the physical science area unit encircled, away from water or oxygen in the atmosphere. 

Less risk of electrical faults like short because of insulation failure, especially where connections are made or broken frequently.

Low infection risk – For embedded medical devices, the transmission of power via a force field passing through the skin avoids the infection risks related to wires penetrating the skin.

sturdiness – while not the requirement to perpetually plug and disconnect the device, there is significantly less wear and tear on the socket of the device and the attached cable.

Disadvantages of Wireless Charging:

Slower charging – because of the lower potency, devices take 15 per cent longer to charge when supplied power is the same amount.

costlier – Inductive charging additionally needs to drive physical science and coils in each device and charger, increasing the complexity and cost of manufacturing.

Inconvenience – once a mobile device is connected to a cable, it can be moved around (albeit in a limited range) and operated while charging. 

In most implementations of inductive charging, the mobile device should be left on a pad to charge, and therefore cannot be rapt around or simply operated whereas charging. 

With some standards, charging will be maintained at a distance, however solely with nothing gift in between the transmitter and receiver.

Thank you!
