This paper presents a concept of the Wireless Charging System for Electric Vehicles. The majority of the EVs in the market are currently using a plug-in charging port, and there are two types of design, one of which is the hybrid model. Hybrid cars have the advantage of a longer driving range as compared to conventional cars because they have a secondary source of energy. However, there are still limitations for the EVs in the current market such as limited power charging stations and low efficiency. This project aims to rebuild a prototype electric vehicle circuit using Tamiya Car, improve the power efficiency, and reduce the power loss. This project also discusses the factors that affect the power efficiency and the types of transmitter and receiver in the market. Compared the different types of coil material, Copper and Litz coils are available in the market. Results show that increasing the number of turns in the coils and using shielding for the coils help to increase efficiency and reduce power loss.
