A Battery Management System (BMS) is essential for lithium batteries, ensuring their safety, efficiency, and longevity. It manages the power flow in and out of the battery, balances the cells, and monitors internal temperatures to prevent issues like overcharging and overheating2. Additionally, a BMS performs critical functions such as controlling charging and discharging processes, and protecting the battery from damage3. When selecting a BMS, consider factors like maximum current rating and the number of series cell groups5. [pdf]
