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.
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.
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.
With passive and active cell balancing, each cell in the battery stack is monitored to maintain a healthy battery state of charge (SoC). This extends battery cycle life and provides an added layer of protection by preventing damage to a battery cell due to deep discharging over overcharging.
Active cell balancing is a more complex balancing technique that redistributes charge between battery cells during the charge and discharge cycles, thereby increasing system run time by increasing the total useable charge in the battery stack, decreasing charge time compared with passive balancing, and decreasing heat generated while balancing.
ncing is used. These methods are not only easy to implement but also provide good performa ce. These balancing circuits are integrated with non-ideal RC models of a lithium-ion battery.
