Functions of BMS in Lithium - Battery Systems

1. Safety Protection
   • Overcharge and Over - discharge Prevention: BMS constantly monitors the voltage of lithium - ion cells. When the voltage reaches a pre - set upper limit during charging, the BMS cuts off the charging current, preventing overcharge. Similarly, during discharging, when the voltage drops to a critical lower level, it stops the discharge process to avoid over - discharge. For example, in an electric vehicle, if the battery is overcharged, it can cause the lithium - ion cells to degrade rapidly, and in some cases, lead to a dangerous situation. The BMS ensures that the battery remains within a safe voltage range, protecting both the battery and the user.
   • Overcurrent and Short - Circuit Protection: By monitoring the current flow in the battery circuit, the BMS can detect abnormal current surges. In the event of an overcurrent or short - circuit, it quickly disconnects the circuit, safeguarding the battery from damage. This is crucial in applications where the battery may be subject to sudden electrical faults, such as in industrial equipment powered by lithium - ion batteries.
   • Temperature Monitoring and Control: Lithium batteries perform best within a specific temperature range (usually around 25 - 40°C). The BMS uses temperature sensors to monitor the battery's temperature. If the temperature rises too high, it may activate cooling mechanisms like fans or liquid - cooling systems. Conversely, in cold environments, it can initiate heating elements to bring the battery to an optimal temperature. For instance, in outdoor energy storage systems, which are exposed to various weather conditions, the BMS's temperature management function ensures the battery's stable operation throughout the year.
2. Cell Balancing
   In a lithium - battery pack consisting of multiple cells connected in series or parallel, there are inevitable differences in the capacity and voltage of individual cells due to manufacturing tolerances and usage patterns. Over time, these differences can lead to some cells being overcharged or over - discharged while others are not fully utilized. The BMS addresses this issue through cell - balancing techniques. It can either bleed off the excess charge from the higher - voltage cells or supply additional charge to the lower - voltage cells, ensuring that all cells in the pack have a similar state of charge (SOC). This not only improves the overall capacity utilization of the battery pack but also extends its lifespan. For example, in a large - scale energy storage installation with hundreds of lithium - ion cells, cell balancing by the BMS is essential to maintain the system's efficiency and reliability.
3. State Estimation
   • State of Charge (SOC) Estimation: The BMS calculates the SOC of the lithium battery, which represents the remaining charge in the battery as a percentage. This information is crucial for users to know how much energy is left in the battery, especially in applications like electric vehicles where range anxiety is a concern. By using advanced algorithms that take into account factors such as current, voltage, and temperature, the BMS can provide an accurate estimate of the SOC.
   • State of Health (SOH) Estimation: SOH indicates the overall health and performance degradation of the battery over time. The BMS monitors various parameters related to the battery's performance, such as internal resistance and capacity fade, and uses these data to estimate the SOH. This helps in predicting the battery's remaining useful life and planning for maintenance or replacement in advance.
