This project introduces a novel wireless charging solution that combines prepaid payment functionality with intelligent parking management to address key challenges in EV charging accessibility.
The proposed system offers contactless charging through electromagnetic induction while implementing a prepaid payment model via RFID authentication. Through a specialized mobile application that provides account management tools and real-time monitoring capabilities, users can easily manage their charging sessions. This design stands out for its multimode power sourcing architecture, which gives renewable energy priority. In order to maximize sustainability and ensure continuous operation, the system intelligently alternates between solar powers, battery reserves, and traditional grid electricity based on current availability. This method greatly lessens reliance on electricity produced during the day from fossil fuels.
By using automated vehicle positioning, the integrated parking management component maximizes the use of the infrastructure. The system uses horizontal movement mechanisms to reposition charged vehicles to non-charging spaces when fully charged vehicles occupy active charging stations while new vehicles arrive. This frees up premium charging positions for energy-demanding vehicles. Throughput capacity is significantly increased during periods of peak usage thanks to this dynamic resource allocation.
User interaction occurs through an intuitive interface combining RFID authentication with numeric input for session duration selection. The system automatically calculates charges based on selected duration and deducts the amount from prepaid accounts, similar to telecommunications payment models. Status updates and charging progress are displayed locally via LCD screens and remotely through the companion mobile application.
Comprehensive safety features include automatic charging termination to prevent battery damage, overload protection circuits to manage electrical anomalies, and secure authentication protocols to prevent unauthorized access. The system’s modular design allows for scalable deployment across various parking environments, from public facilities to residential complexes.
This integrated approach to EV charging infrastructure represents a significant advancement in supporting sustainable transportation adoption by eliminating physical connection requirements while optimizing resource allocation through intelligent management systems and a scalable approach to modern transportation management.
