The increasing adoption of electric vehicles (EVs) necessitates the development of sustainable, efficient, and intelligent charging infrastructures. This paper proposes an advanced solar-based wireless EV charging system integrated with Internet of Things (IoT) technologies for real-time monitoring and control. The system utilizes photovoltaic panels as the primary energy source, which charge a storage battery through an efficient power conditioning unit. The stored energy is supplied to an inductive power transfer (IPT) transmitter coil embedded within the roadway infrastructure. When an EV equipped with a receiver coil passes over the transmitter, energy is wirelessly transferred through electromagnetic induction and rectified to charge the vehicle battery. An ESP32 microcontroller serves as the central control unit, acquiring real-time data from voltage and current sensors placed at both the solar input and load sides. The system is further enhanced with IoT integration using the Blynk application and ThingSpeak cloud platform, enabling remote monitoring, data logging, and performance analysis. A 16×2 LCD provides local visualization of system parameters, while a relay module ensures intelligent power management and protection. Additionally, an IR sensor facilitates vehicle detection for efficient energy transfer activation. The proposed system eliminates dependency on conventional grid-based charging, supports dynamic (in-motion) charging, and enhances energy utilization through renewable sources. The integration of IoT platforms ensures scalability, user accessibility, and predictive maintenance capabilities. This work demonstrates a viable approach toward smart, autonomous, and sustainable EV charging infrastructure for next-generation transportation systems.
