AI Customer Serviceneeds two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.
Number of cells: The balancing system becomes more complex with the number of cells in the battery pack. Balancing method: Choose active and passive balancing techniques based on the application requirements. Balancing current: Determine the appropriate balancing current to achieve efficient equalization without compromising safety.
Simultaneous cell balancing can also be accomplished for multiple cells at once by means of comparator-based circuit solutions which facilitate the decision of bypass or energy transfer considering the entire battery pack. Anton Beck, “Why proper cell balancing is necessary in battery packs”, Battery Power.
A: To implement cell balancing in your battery system, follow these steps: Assess your battery needs and determine the most suitable cell balancing technique for your application. Consult with battery specialists or engineers for guidance on implementing cell balancing in your system.
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
After performing cell balancing, each cell's SoC reaches 60 % (average SoC) which signifies that all cells have reached to same level or balanced. Therefore, SoC balancing is crucial in EV battery pack to increase the usable capacity. Fig. 3. Charge among five cells connected in series before and after SoC balancing.
