    In the future transport area, electric vehicles are considered as replacement of oil powered internal combustion engine driven vehicle to achieve environmentally-friendly transportation. Even though electric vehicle (EV) usage is currently increasing, a technology breakthrough would be required to overcome battery related drawbacks. To address battery related limitations, the concept of Wireless Power Transfer (WPT) enabled EV has been proposed. Wireless Power Transfer system transfer electric energy from power source to load without wired connection conveniently. WPT is achieved through the affordable inductive coupling between two coils termed as transmitter and receiver coil. In EV charging applications, transmitter coils are buried in the road and receiver coils are placed in the vehicle. Wireless Power Transfer has the potential to overcome the drawbacks of wired chargers and eliminate some hurdles towards vehicle electrification and sustainable mobility. Even though inductive coupling has been applied in some applications of WPT, it is still not efficient enough to transfer high power at the kilowatts level due to weak coupling between the transmitter and the receiver. Using optimally-specified resonant circuits along with inductive coupling can enhance the coupling and make the system more efficient for practical applications. This research aims to design and analyze the performance of a WPT circuit. The optimal specification of a resonant circuit is studied and discussed. Theoretical calculations are performed to find the component values in the circuit to reach. The WPT system is verified by performing simulation tests in the MATLAB/SIMULINK environment. From the sustainability perspective, performance is defined in terms of energy, environmental, and economic metrics, and policy drivers and issues of health and safety are also examined.
