WIRELESS CHARGING

WIRELESS CHARGING

Wireless charging is the methodology of transmission an electrical current from a power source to a receiving device without the use of a physical connection.
Wireless charging uses an electromagnetic field to transfer energy between two objects through coils. The receiving device can be smartphones, industrial forklift industries and other electronics devices.

 Induction chargers use an induction coil to create an alternating electromagnetic field from within a charging base station, then induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery.
The technology comes to help easy charge with any charger for a device that has a capability of acquire wireless connection.

Similar with the charging of motor vehicle is maintained wireless technology by advanced parking assist with the EV which changes the efficiency of charging as per the parking location. An EV can always be charged at maximum efficiency
By eliminating the use of a physical connector or cable, wireless charging provides a number of advantages including, efficiency, cost and safety.

How it works

The main voltage is converted into high frequency alternating current. This alternating current (AC) is sent to the transmitter coil by the transmitter circuit and induces a time varying magnetic field in the transmitter coil.

Alternating current flowing within the transmitter coil induces a magnetic field which extends to the receiver coil (when within a specified distance). The magnetic field generates current within the receiver coil of the device.  

Current flowing within the receiver coil is converted into direct current (DC) by the receiver circuit, which can then be used to charge the battery.

WIRELESS CHARGING IN CAR SYSTEM

Wireless technology are widely used in car charging system where by magnetic flux is generated vertically from the ground when electricity passes through the Ground Transmission Unit’s primary coil, which is installed on the surface of the parking place.

An electrical pressure is generated by overlapping with the secondary coil in the Vehicle Receiver Unit in the vehicle, and electricity is supplied from the first coil to the second one electromagnetic induction.

 This system become most reliable for the utilize of the sunlight and convert into electrical device and hence lead to connected with charging system of car, magnetic flux will generate more electricity when the wheel rotate and create an induction.

The designed engine of car is maintained that there is more production of the electricity that allows the car to travel with a huge charge.

      The mechanism of electricity transmission occurs in four ways

        Electricity is applied to the cool on the ground

        A magnetic field occurs from coil on the ground

        The magnetic field passes through the coil on the wheel

        An electric current occurs on the coil of wheel

Merits of wireless charging

There is no radiation transfer of energy which will require a lot of designed materials 

There is no energy is lost hence utilization will be used 
There is no corrosion of the plate during recycled of energy also in the skin doesn’t corrode 

Durability in such a way doesn’t produce tear and wear

Demerits of wireless charging

Its more expensive due to the electronics device used are manufactured 
Lower efficiency the performance of charging is poor 
Waste heat during charging it can lose heat energy
