The accelerated growth of electric vehicles (EVs) has led to an increased demand for effective, dependable and user- friendly charging infrastructure for EVs. In the Indian scenario, the projections are that income of the EV fleet is expected to grow from around 5.6 regional renewable electrical vehicle in 2025 to nearly 28 sq.v parallel in 2030 thus leading to a substantive improvement in public pay charge deficit. As a result motorists may start facing extended waiting times, a congested charging point, and a wastage of energy at the conventional charging points. This research reports the design and implementation of the wireless charging prototype that realizes the direct power transfer from the electrical grid to electric cars through inductive wireless power transfer (WPT). The system uses the electromagnetic induction process which allows the contactless transmission of power from a transmitter coil that is part of the ground assembly to a receiver coil carried on the underbody of the vehicle. The technology behind the prototype utilizes Internet of Things (IoT) technology via ESP32 microcontroller and ESP8266 Wi-Fi module which sends real-time charging data such as battery level, input voltage, current flow, charging time, etc., to a mobile app. In addition, the system includes a buck - boost converter to stabilize the voltage to comply with the specifications of the vehicle batteries. Experimental results show that the average power transfer efficiency is 68o to 80o percent depending on the alignment of the coils and air gap between the coils. The mobile application is used to remote control of charge operations, i.e., start and end charge cycles, and notify at completion, hence increasing user convenience. This research illustrates the possibility of contactless EV charging and highlights that it could help reduce pressure on the infrastructure and enhance interaction between the grid and the car. The findings support the move to intelligent systems for charging to be combined with renewable energy resources and multivariate technologies for self-driving vehicles.
