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.
Passive balancing is perhaps the simplest form of cell balancing with a resistor that is switched on and off across the cell. In the example shown with the 3 cells the balancing resistor would be switched on for the centre cell. Discharging this cell and losing the energy to heat in the balance resistor (typically 30Ω to 40Ω).
Consequently, the authors review the passive and active cell balancing method based on voltage and SoC as a balancing criterion to determine which technique can be used to reduce the inconsistencies among cells in the battery pack to enhance the usable capacity thus driving range of the EVs.
It provides a fairly low cost method for balancing the cells, but it wastes energy in the process due to the discharge resistor. Passive balancing can also correct for long-term mismatch in self discharge current from cell to cell. Analog Devices has a family of multicell battery monitors that include passive cell balancing.
For the configuration of the battery balancing, it is classified as the passive balancing method (PBM) and the active balancing method. The PBM usually dissipates the energy through the paralleling resistors. In contrast, the active balancing method utilizes one part of the battery string to charge another.
An advanced method of managing an equal SOC across the battery pack’s cell is known as active battery balancing. Instead of dissipating the excess energy, the active balancing redistributes it, resulting in an increased efficiency and performance at the expense of elevated complexity and cost.
