This article has conducted a thorough review of battery cell balancing methods which is essential for EV operation to improve the battery lifespan, increasing driving range and manage safety issues. A brief review on classification based on energy handling methods and control variables is also discussed.
The BMS compares the voltage differences between cells to a predefined threshold voltage, if the voltage difference exceeds the predetermined threshold, it initiates cell balancing, cells with lower voltage within the battery pack are charged using energy from cells with higher voltage (Diao et al., 2018).
Due to manufacturing irregularity and different operating conditions, each serially connected cell in the battery pack may get unequal voltage or state of charge (SoC). Without proper cell balancing, serious safety risks such as over-charging and deep discharging in cells may occur.
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.
