How Much Cell Balancing Current Do You Need for Optimal Battery
The role of the BMS balancing current is to equalize the State of Charge (SoC) of individual cells within a battery pack. By achieving this balance, all cells reach the same SoC during the charging and discharging cycles. As a result, the battery''s charge capacity is optimized, allowing it to deliver maximum power, constrained only by the

How to balancing a battery?
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.
How does battery balancing work?
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.
What happens after balancing a battery?
After balancing, the capacity of a battery is limited at both ends by the cell with the lowest capacity (or, in extreme cases, by the cell with the highest internal resistance) A balanced battery is one in which, at some State Of Charge, all the cells are exactly at the same SOC. This can be done at any SOC level.
Can a control circuit drain balance current near end of charge?
More balance current will occur near end of discharge and end of charge than in the middle of the cycles due to the flatness of the voltage curve in the middle. Also it may not be desirable to drain balance current near end of discharge, thus a controlling circuit can be used to only drain balance current near end of charge on a charging cycle.
What's the difference between balancing and redistributing a battery?
That's done by a different technique: Redistribution . Redistribution allows use of all the energy in the battery; it requires significantly higher currents than balancing. The point of balancing is to maximize the charge that the battery can deliver, limited only by the cell with the lowest capacity.
What happens if battery balancing is not accurate?
For example a slight increase in charging voltage from 4.2V to 4.25V will degrade the battery faster by 30%. So if cell balancing is not accurate even slight overcharging will reduce the battery life time. As the batteries in a pack get older few cells might be weaker than its neighboring cells.
