Homogeneous coil design for wireless charging electric vehicles

Abstract

Electric vehicles are slowly becoming the first option for consumers. As time passes, the challenges limiting the chances of its existence are being reduced by the efforts of the researchers; they have the idea of having a green world and aim to achieve it by eliminating any source of pollution that found a green replacement. However, how well the performance of electric vehicles is not enough to make an industrial change. While there are challenges yet to be solved additionally, the main problem is the time to fully charge the battery in static and dynamic charging. However, time is rapidly being enhanced for static charging due to the fast charging cable improvements. Still, for dynamic charging, it is all about the efficiency of the connection during the power transmission. In this project, a homogenous coil has been designed, and the main focus is the radius of the coil. The design is tested under different conditions, and the optimal case is when the radius of the transmission coil is bigger than the radius of the receiver coil. The design has recorded an efficiency of up to 95%. Lastly, an enhanced method has been produced to wirelessly charge the electric vehicle with the help of homogeneous pads.
