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.
Battery cell balancing brings an out-of-balance battery pack back into balance and actively works to keep it balanced. Cell balancing allows for all the energy in a battery pack to be used and reduces the wear and degradation on the battery pack, maximizing battery lifespan. How long does it take to balance cells?
The BMS compares the voltage differences between cells to a predefined threshold voltage, if the voltage difference exceeds the predetermined threshold, it initiates cell balancing, cells with lower voltage within the battery pack are charged using energy from cells with higher voltage (Diao et al., 2018).
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.
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.
A typical battery balancer consists of several key components: Cell voltage monitoring: Precision voltage measurement circuits for each cell. Balancing circuit: Either passive (resistors) or active (DC-DC converters, switched capacitors) components for charge redistribution.
