Having a reliable Battery Management System (BMS) is essential for ensuring the safety, efficiency, and longevity of lithium-ion batteries used in various applications such as electric vehicles and renewable energy systems. A robust BMS monitors battery health, optimizes performance, and prevents hazardous situations like overheating or overcharging.
What Are the Key Functions of a Battery Management System (BMS)?
A BMS performs several critical functions that are vital for maintaining battery health and safety:
- Monitoring: Continuously tracks voltage, temperature, and current to ensure safe operation.
- Protection: Prevents overcharging, deep discharging, and short circuits.
- Balancing: Ensures all cells within the battery pack are charged evenly to optimize performance.
