A Battery Management System (BMS) is an electronic system that monitors and controls rechargeable battery packs by regulating voltage, current, temperature, charging, and discharging to ensure safe and reliable operation.
Expanded Explanation
A BMS functions as the control layer of a battery pack. It continuously monitors individual cells and the overall pack to ensure operation remains within defined safety limits. This includes preventing overcharging, overdischarging, excessive current draw, and overheating.
In multi-cell lithium battery packs, cells naturally drift out of balance over time. A BMS addresses this through cell balancing, helping maintain consistent performance and extend battery life. Many BMS designs also provide diagnostic data such as State of Charge (SoC), State of Health (SoH), and fault conditions.
Why it matters
Lithium batteries store high energy in compact form factors, making precise control essential for safety and longevity, especially in regulated environments.
