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.
Traditionally, lead acid batteries have been able to "self-balance" using a combination of appropriate absorption charge setpoints with periodic equalization maintenance charging. This characteristic of lead acid batteries is enabled by a secondary electrolysis (hydrogen producing) reaction within the electrolyte of the batteries.
Battery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection. Quality Li-ion cells have uniform capacity and low self-discharge when new. Adding cell balancing is beneficial especially as the pack ages and the performance of each cell decreases at its own pace.
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.
There are two main methods for battery cell charge balancing: passive and active balancing. The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries. These types of batteries can be brought into light overcharge conditions without permanent cell damage.
This characteristic of lead acid batteries is enabled by a secondary electrolysis (hydrogen producing) reaction within the electrolyte of the batteries. The produced hydrogen gas either vents (for flooded batteries) or is recombined into the electrolyte (for OPzV Gel and AGM batteries), expelling energy.
