Passive balancing is one of the most straightforward battery balancing methods used in lithium battery packs. It operates by dissipating excess energy from overcharged cells as heat through resistors. This process ensures that all cells within the battery pack achieve a uniform voltage level, preventing overcharging and undercharging issues.
Balancing the charge on a battery pack connected in series and parallel is crucial due to manufacturing discrepancies and distinct performance of each cell in a standard battery pack. In this paper, a switched-resistor passive balancing-based method is proposed for balancing cells in a battery management system (BMS).
Bleeding Resistor: Passive Battery Balancing is commonly deployed as the bleeding resistor. A resistor is linked in parallel with each cell in this technique, and the cells having greater voltage selectively involves the resistor with the help of a control system.
The presented research actually proposes a novel passive cell balancing system for lithium-ion battery packs. It is the process of ramping down the SOC of the cells to the lowest SOC of the cell, which is present in the group or pack. In simple words, consider a family having 5 members, such as parents and children’s.
