Smart Charging System for Mobile Charges and Laptops Using RFID and Raspberry Pi

This project introduces a smart charging system for mobile devices and laptops that utilizes Radio Frequency Identification (RFID) technology and Raspberry Pi. The system addresses the challenges of inefficient charging practices and the inconvenience of managing multiple chargers and devices. By employing RFID for device identification and authentication, the system simplifies the charging process and ensures optimal charging for various devices. The Raspberry Pi acts as the central control unit, managing the charging process based on device information retrieved from RFID tags. Real-time feedback on battery status and estimated charging time is provided, while intelligent energy management into optimize power usage and minimize wastage. This system will limit the charging time to each user with 5 min and the LCD display showing the actual time left. This system will cut off the current automatically which is in fully charged. The simulation and experiment proved that mobile phone and laptop charging output voltage DC is within 5 VDC to 20 VDC, respectively. Moreover, output current estimated in the range 0.5–5 A. The significant output of this research is a streamlined and user-friendly charging experience, eliminating compatibility issues and promoting sustainable practices. Overall, this smart charging system offers a convenient and efficient solution for our increasingly device-dependent lifestyles. In conclusion, the smart charging system presented in this project utilizes RFID and Raspberry Pi to create an intelligent and efficient charging solution for mobile devices and laptops. By simplifying the charging process, optimizing charging parameters, the system offers a convenient and sustainable solution for our increasingly device-dependent lifestyles.
