IoT-Based Smart Battery Charging and Swapping Station for Electric Two-Wheelers

This paper has presented an IoT-based battery charging and swapping station that unites battery monitoring, cloud synchronization, a web application with live availability and reservation, and RFID and PIN-based secured access around a single ESP32 controller. A hardware prototype and the web application have been built, and system integration and testing are under way. No performance figures are claimed here; the planned tests will measure swap time, accuracy of the voltage, current and charge-state readings, reservation and unlocking reliability, and charging behaviour under BMS protection, and these results will be reported when testing is complete. Further work could extend the station to more slots, add battery-health estimation and demand forecasting, and align the battery identification with the interoperability and tracking provisions of the national framework [5].
