IoT-Based Smart Battery Management System with Active Cell Balancing and Intelligent Thermal Protection for Lithium-Ion Battery Packs

This whole project was about building an ESP32-based Battery Management System—tracking voltage, keep-ing cells balanced, stopping overheating, and showing you what’s happening on a screen or online. Every cell gets monitored for trouble like poor voltage or rising heat, and the system reacts fast if things start getting dicey.   The tests prove that checking every battery channel helps spot issues early. Smart sensors and quick con-trols  work  together  to  keep  things  safe.   The ESP32? Honestly, it just works. It’s affordable, flexible, and solid when it comes to handling sensors, screens, and wireless connections. With IoT, you can check your battery status from anywhere and dig into logs if something goes wrong. If you need reliable bat-tery management, this is a great place to start.   This prototype already makes battery monitoring safer and smarter. But to really step things up, it needs better hardware, smarter sensors, and more testing in the real world. Upgrades like active balancing and automatic cutoffs are key if you want to boost lifespan, efficiency, and                                                                  reliability.   Bottom line: The system already works with EVs, solar arrays, backup power, or anything else that needs good battery care. With more improvements—AI, health tracking, cloud support, tougher hardware—it’s ready to become a truly top-notch, dependable Battery Man-agement System.
