ABSTRAC
This study aims to design and implement an analog-based Battery Management System (BMS) utilizing a TL431 comparator and a BD140 transistor to provide overcharge protection for a 3S lithium-ion battery configuration. The proposed system is integrated with a 10-Watt photovoltaic (PV) solar panel as the energy source and is equipped with a monitoring subsystem consisting of an INA219 current and voltage sensor and a 20×4 LCD, controlled by an Arduino Uno microcontroller. The BMS design emphasizes the detection of the maximum voltage threshold of each battery cell and the disconnection of the charging path when the cell voltage exceeds the upper safety limit of 4.2 V. Experimental results indicate that the protection circuit is activated when the voltage of each cell reaches approximately ±4.3 V. Although this activation voltage slightly exceeds the nominal safe limit of lithium-ion cells (4.2 V), the system is able to effectively terminate the charging process and prevent excessive current from flowing into the battery. Overall, the proposed BMS demonstrates reliable overcharge protection performance, and all system components operate in an integrated and stable manner in accordance with the design specifications.
