Demonstrates improved voltage balancing in lithium-ion battery packs, suggesting enhanced performance and safety.
This paper presents the design and implementation of an advanced active charge equalizer for lithium-ion battery packs aimed at improving voltage balancing, safety, and overall energy utilization. In multi-cell battery systems, variations in cell characteristics lead to unequal voltage distribution, resulting in reduced capacity, overcharging risks, and decreased battery lifespan. To address these challenges, an intelligent battery management system (BMS) based on the ESP32 microcontroller is proposed. The system continuously monitors individual cell voltages using sensor modules and employs relay-controlled selective charging to prevent overcharging and ensure balanced operation across all cells. A real-time web-based dashboard is integrated for remote monitoring and control via WiFi. The proposed approach achieves effective voltage equalization with minimal deviation between cells, thereby enhancing battery performance and extending operational life. Additionally, the system offers a low-cost, scalable, and efficient solution suitable for electric vehicles, renewable energy storage, and portable electronic applications. Experimental results demonstrate improved balancing accuracy and reliable system performance under varying conditions.
