What Does a BMS (Battery Management System) Actually Protect?
Over-voltage, under-voltage, over-current, temperature protection and cell balancing explained.
A Battery Management System (BMS) monitors and controls a lithium-ion battery pack to ensure safe operation, optimal performance, and long cycle life.
Key protections:
- Over-Voltage Protection (overcharge)
- Under-Voltage Protection (overdischarge)
- Over-Current / Short-Circuit Protection
- Over-Temperature Protection
- Cell Balancing
For LiFePO₄ packs, a quality BMS is essential to realize the chemistry's long cycle-life potential.
