Smart Solar and Grid Assisted Dynamic Wireless Power Transfer System For Electric Vehicles with Automatic Billing and Power monitoring

Abstract

The increasing adoption of Electric Vehicles (EVs) has created a need for efficient, convenient, and intelligent charging infrastructure. Conventional plug-in charging requires the vehicle to remain stationary and physically connected to a charging point. This project proposes a Smart Solar and Grid Assisted Dynamic Wireless Power Transfer System for Electric Vehicles with Automatic Billing and Power Monitoring to overcome these limitations. The proposed system uses wireless power transfer (WPT) technology to transfer electrical energy from a transmitter coil installed below or along the roadway to a receiver coil installed underneath the electric vehicle. The system can receive energy from both solar photovoltaic (PV) panels and the electrical grid. Solar energy is given priority when sufficient power is available, while grid power is used as a backup or supplementary source. During vehicle movement over the charging section, wireless charging can be activated automatically using vehicle detection and control circuitry. Sensors measure parameters such as voltage, current, power, energy consumption, and charging duration. A microcontroller or IoT controller sends the measured data to a monitoring platform. An automatic billing module calculates the charging cost based on the amount of electrical energy transferred to the vehicle. The system can therefore provide contactless charging, renewable-energy utilization, real-time power monitoring, energy measurement, and automatic billing in a single platform. The proposed system can be useful for smart highways, EV charging lanes, parking areas, bus stops, commercial charging stations, and future intelligent transportation infrastructure.
