The Voltage Balancing Circuit is a key element in Li-ion battery management, addressing the need to balance individual cell voltages to enhance overall battery pack performance. Its primary goal is to equalize the voltage across all cells, preventing overcharging or over-discharging of specific cells that could lead to premature battery failure.
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.
The BMS should incorporate a cell balancing circuitry that redistributes charge between cells as needed to maintain balance. This can be achieved using techniques such as active or passive cell balancing. Temperature is another critical parameter to monitor in a battery pack.
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 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.
