Modeling and Development of Wireless Power Transmission System for Electric Vehicles

Abstract

The main objective of this paper is to develop a sustainable Wireless power transmission (WPT) model. WPT is the technique of transferring electric energy from a power source to a load without any contact between them. This process can be done through different methods using different topologies, which include Series Series (SS), Series Parallel (SP), Parallel Series (PS), and Parallel Parallel (PP). One of the most widely used methods in WPT is inductive power transfer. The main advantages of WPT – it allows charging for multiple devices, has high charging speeds, low cost, less maintenance, and higher efficiency than wired charging. Despite significant advancements in charging solutions, the system still has various issues, such as coil position, the number of receiving coils, the distance between transmitter and receiver coils, high initial cost, and impacts on its sustainability. This paper discusses the simulation model of the WPT model using SS topology in the JMAG software and analyzes the effect of the position of coils and distance between transmitter and receiver coils on the output. This simulation model can further be used to build a prototype for charging EV batteries.
