As a student at the MSc in « Applied Automation Systems » that is coordinated by the Department of Production Engineering and Management of the “International University of Greece” i had to write my MSc study . My study’s theme was « Design & Implementation of Wireless Electric Vehicle (EV) Charging System Using Solar Energy » . At this study was designed and implemented a wireless charging system for electric vehicle that Is powered also from solar energy , using solar panel . For the implementation of the application, a coil without a core, 140 turns, 18 cm in diameter and a conductor cross-section of 0.75 mm² was chosen. In the power supply circuit the pulse generation was chosen to be done with a 555 IC Timer [26] and bd 139[27] transistor. The battery chosen was a 12 V battery and for the charging by Solar energy a solar panel with dimensions 255*190*18 mm 5W Power was chosen together with the necessary charge controller. For the secondary coil circuit it was chosen to make a rectification with SB 260 [29] schottky diodes and for voltage stabilization an lm7805[28] voltage stabilizer was chosen. An 18650 lion 3.6 V 2900 mAh battery with its charger was chosen for the battery of the electric vehicle. The design was initially carried out at the laboratory level with several measurements and many tests and the factors influencing the operation of the specific application were identified and highlighted. The measurements taken were visualized and analyzed below and the appropriate choice of materials and the method used to implement the application was chosen. Then a model was implemented for the detailed presentation of the specific application and the issuance of the final conclusions. The final conclusions drawn from the preparation of the diploma thesis were that this application had some critical parameters that affected the final result such as the distance and the way of implementation of the application and the advantages presented by the application in terms of flexibility in placement and performance that offers . The efficiency of the system reached 51% and decreased as the distance between the coils increased. Finally, with some modifications, the degree of performance could be increased, something that did not contribute and was not the main objective of the work.
