Thank you sir, giving quick reply,but by plug in more power losses, and very harmful for high level charging.

But I have very much interested on wireless power transfer in ev battery charging

Sir I have small request, what are the research gaps and objectives in the topic and how to start my work, please help me sir

Dear Bhukya,

interoperability requirements kill the cat.

Standards demand, that a 3kW receiver can be powered from a 11kW sender and vice versa.

The nonsymmetric components, the wide range of battery voltages to cover and the standard's restrictions to a frequency band of 80-140kHz make higher power charging on inductive systems less attractive.

In public use, the enormous cost of installation contribute to high system cost.

In private use - why pay for a second system if your car has wired on-board chargers already?

And why tolerate higher system-cost while at the same time sacrificing efficiency?

There are no gaps in research - the topoc is well documented and my find it's use in some niches but not in larger scale for EVs.

Cheers - Martin
