Modeling and simulation of wireless electric vehicle charging using solar and wind energy

Abstract

The fuel existing vehicles produce air, noise pollution and it produces many other effects. Due to these impacts, conventional fuel for vehicles is changing to battery. Hence there is increase in number of EV's recently. Charging station is one of basic need for them. In EV's there is a major disadvantage that it could not travel more than few hundred kilometres. So, in this paper we are aiming for modelling and simulation of wireless electric vehicle charging using solar and wind energy. The battery bank in charging station will be charged from solar and wind based on availability. The wireless charging of Electric vehicle is based on inductive power transfer between two mutually coupled coils, one is "primary"connected to rechargeable battery bank, charged by solar and wind energy. An inverter is connected on this primary coil side. And other "secondary coil"is connected to battery of electric vehicle through rectifier and voltage regulator. The advantages provided by the wireless charging are in terms of safety, comfort, as the driver can avoid the danger of using power cord and he needs to park vehicle without the need of plug-in operation to start charge battery of vehicle. PV and wind energy resources are renewable and available resource for future energy generation. The use of solar and wind energy is pollution free and eco-friendly in nature. By taking the dynamic charging needs of EV's, the design of charging circuit is formulated and validated in MATLAB Simulink.
