Modelling & Fabrication of Wireless EV Battery Charging System Using PV Array

Abstract

This paper presents a wireless solar charging system to identify a PV array's maximum power point (MPP) that can charge electric vehicles (EVs). The system includes solar, WPT coil, ESP32, Arduino microcontroller, and lithium-ion battery. The WPT coil initiates a magnetic field to transfer power to the battery, thus minimizing the establishment of physical contacts and outlets. The software technologies used here include the Integrated Development Environment or IDE in the form of Arduino IDE for programming and Proteus Software for simulating the systems. This wireless charging method provides the comparable benefit of flexibility; it has the potential for routine EV charging regardless of the climate. The study does not emphasize coming up with a new wireless charging model much but more on modifying an existing one. As such, it is not very concerned with the technologies used in capturing solar energy or charging batteries. The primary goal is to share the efficiency of practical charging strategies for EVs by integrating wireless power transfer into the charging system, eliminating the need for charging cords. This approach is promising for future developments in sustainable personal transportation, possibly enhancing the practical and convenience aspects of the indicated means of EV charging.
