needs 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.
A battery balancer is a device or circuit designed to equalize the charge levels across multiple cells in a battery pack. It is a critical component of a battery management system (BMS) that ensures the battery pack’s optimal performance, safety, and longevity. A typical battery balancer consists of several key components:
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?
Control logic: Microcontroller or dedicated IC to manage the balancing process. Communication interface: This is for integration with the overall battery management system. Protection circuits: To prevent overcharging, over-discharging, and thermal issues. Temperature sensors: These monitor cell and ambient temperatures.
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.
