ii. Improving the safety and dependability of a BMS is critical for applications that rely on battery technology, such as EVs. Several main tactics can be used to achieve safety and reliability of BMS. Implementing redundancy and fault-tolerant designs ensures that the BMS can continue to function in the case of component failure.
The findings of the research show that lowering the number of battery submodules reduces balancing current and improves balancing efficiency. The duty ratio adjustment in power switches controls the balancing current or energy transferred within a single switching cycle.
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.
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.
