BMS is crucial to Battery Energy storage systems. Its main benefits are:

Ensure functional safety: Whether it is a large lithium-ion Battery Pack or a small battery pack, it may cause danger due to improper management. BMS can avoid battery management errors and ensure the personal safety of users of products using lithium-ion power systems.

Extend service life and improve reliability: Through battery pack protection management (electrical and thermal management), ensure that all batteries are used within the declared SOA requirements, protect the batteries from damage during intense use and rapid charge and discharge cycles, make the system stable, and provide many years of reliable service.

Optimize performance and driving range: Use the inter-cell balancing function in the battery pack capacity management to balance the SOC of adjacent batteries and achieve the best battery capacity. Without this function, the battery pack is prone to failure due to self-discharge, charge and discharge cycles, temperature effects and aging.

Enables diagnosis, data collection and external communication: All battery cells are continuously monitored, and the recorded data is used for diagnosis and calculation of battery SOC. This information is not only used in the balancing algorithm, but can also be transmitted to external devices to indicate available energy, estimated range or life, and feedback on the health of the battery pack.

Reduce costs and warranty risks: Although the introduction of BMS will increase costs, its protection and preventive maintenance in terms of functional safety, life reliability, performance endurance, diagnosis, etc. can reduce the overall cost including warranty costs.
