Battery Management Systems (BMS) play a crucial role in ensuring the safe and efficient operation of batteries, and one of their key functions is cell balancing. In a battery pack, individual cells may have slight differences in their capacity, internal resistance, and state of charge (SoC) due to manufacturing tolerances or differences in usage patterns. These differences can lead to uneven charging and discharging, which over time can cause some cells to be overcharged or over - discharged, reducing the overall performance and lifespan of the battery pack.
The balancing function of BMS is designed to address these cell - to - cell variations. There are two main types of cell balancing methods: passive and active. Passive balancing typically uses resistors to dissipate the excess energy of the higher - voltage cells. When a cell reaches a certain voltage threshold during charging, a resistor is connected across the cell to bleed off the excess charge, bringing its voltage down to match that of the other cells. However, this method has limitations as it wastes energy in the form of heat, which is not ideal for energy - efficient systems.
Active balancing, on the other hand, is a more advanced and efficient approach. It transfers energy from cells with higher SoC to those with lower SoC. This can be achieved through various techniques, such as using inductors, capacitors, or DC - DC converters. For example, some active BMS systems use flyback converters to transfer energy between cells. When a cell has a higher voltage than the average of the battery pack, the converter transfers energy from this cell to a lower - voltage cell. Active balancing can operate during both charging and discharging processes, not being restricted by the battery's charging, discharging, static, or dormant states. Once the cell voltage value and voltage difference reach the set condition, the power transfer will be turned on intelligently until the voltage is balanced.
The benefits of effective cell balancing are numerous. It can extend the overall lifespan of the battery pack by ensuring that all cells age at a more uniform rate. For example, if one cell in a battery pack is consistently overcharged due to imbalances, it will degrade much faster than the other cells. By equalizing the charge levels, the wear and tear on all cells are more evenly distributed. Additionally, cell balancing can improve the performance of the battery pack. A balanced battery pack can deliver more consistent power output, reducing the likelihood of voltage drops during high - current discharges. It also allows for better utilization of the overall capacity of the battery pack, as cells are not limited by the lowest - capacity cell in the pack.
