Why wireless charging is needed?

The use of combustion engines—primarily in vehicles—is expanding quickly along with population growth. Although a result, as fossil fuel resources are under strain and environmental degradation and global warming are getting worse, fossil fuel use is also growing daily. Using electric vehicles is a good way to solve this issue (EV). The use of wireless charging techniques can make it easier to charge these EVs. Utilizing an inductive-based wireless charging system (WCS) for EVs offers operator-free charging and is more practical, adaptable, dependable, and safe than conductive charging.
 
Two coils are required for the installation of the charging system, one of which is located inside the EV (secondary coil/receiver coil) and the other is installed in the parking garage (primary coil/transmitter coil). To lessen the additional stress on the EV, the side coil should be lightweight and compact in size.
