Enhancing Capabilities of Wireless Transmission for Electric Vehicle

Era of electric vehicles has begun, now it is time to focus on enhancing the present technologies and to improve efficiency of current system being used. The paper introduced wireless power transmission technique using resonance inductive coupling method for charging electric vehicles, also using same for charging vehicle in dynamic condition. We have also mentioned factors affecting efficiency of wireless power transmission and ways to overcome such problems. As the system is helpful to transmit power wirelessly it will help the user to charge EV (electric vehicle) in easiest way without use of wires, also to improve charging efficiency with reduced charging time and losses. Better charging efficiency and simplifying process of charging is the main objective behind this project. The Changes in resonant frequency due to change in values of circuit components are studied with the help of some calculations and increased frequency has a direct relation with power transfer between the coils and indirect relation with efficiency of the magnetic resonance coupling wireless power transmission system can be concluded.
