A review Wireless charging strategies for Electric Vehicle

Abstract: This paper introduces an updated method for battery charging via renewable energy grids, utilizing solar panels and wind turbines. A voltage regulator maintains a constant output voltage, while a Buck-Boost converter transforms LVDC to HVDC. A rectifier circuit rectifies harmonics produced at the wind turbine output. Stored power is available for various electrical components through a continuous output mechanism at the battery side. The project also presents wireless EV charging, focusing on resonant technology for efficient, cost-effective power transmission through resonance coupling. Solar and wind energy serve as the primary energy sources. Buck-Boost converters, voltage regulators, and C smoothing are employed for efficient operation. Transmitter coils coupled with batteries facilitate wireless power transfer. The abstract addresses challenges in EV charging within office environments, including manual cable connections, limited options, safety concerns, and the absence of dynamic charging capabilities. It proposes an innovative WPT system for office parking areas, integrating renewable energy resources and IoT technology. The system automatically initiates charging upon EV parking, with real-time monitoring through the Blynk application. IoT and RFID technologies provide dynamic updates on charging slot availability and implement strict security protocols. A case study demonstrates the system's efficacy in office settings, achieving a 95.9% IRR, lower NPC of USD 1.52 million, 56.7% power contribution by RERs, and significant reduction in annual carbon emissions to 173,956 kg CO2.
