In the domain of Battery Management Systems (BMS), there are two types of Cell Balancing techniques available. Let's get on them one by one. In an active cell balancer, energy transfers from a higher voltage to a lower voltage cell within the battery. In other words, the cell with higher SoC transfers energy to a lower SoC cell.
Battery Cell Balancing also means battery redistribution to improve the overall potential of the battery pack and emphasize each cell's longevity. Cell Balancing enhances the State of Charge (SOC) of your battery. An imbalance is created when every cell in the connected series of the battery pack depicts a different SOC.
By identifying and mitigating unsafe operating conditions, the BMS ensures the safe operation of the battery pack and the connected device. It prevents overcharging, over discharging, and thermal runaway. To maintain uniformity across individual cells, the BMS incorporates a cell balancing function.
This battery balancing method uses resistors in a balancing circuit that equalizes the voltage of each cell by the dissipation of energy from higher cell voltage and formulates the entire cell voltages equivalent to the lowest cell voltage. This technique can be classified as a fixed shunt resistor and switching shunt resistor method.
It consists of accurate control strategies, careful design, strong safety mechanisms, and complete diagnostics and maintenance methods. Flawless integration is a must as it ensures that the balancing methods work effectively within the BMS, optimizing the battery pack's performance, improving protection, and expanding its life.
