Battery balancing maximizes the useful capacity of the pack by guaranteeing that all cells in the pack have the same SOC. This implies that you can maximize the use of your battery pack whether you're driving an electric car or using a renewable energy storage system to power your home.
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.
This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1. Comparison of various cell balancing techniques based on criteria such as cost-effectiveness, scalability, and performance enhancement
A BMS (act as the interface between the battery and EV) plays an important role in improving battery performance and ensuring safe and reliable vehicle operation by adding an external balancing circuit to fully utilize the capacity of each cell in the battery pack. The overview of BMS is shown in Fig. 2. Fig. 2. Overview of BMS.
The battery module is protected from overcharging and overdischarging by the BMS. The charge level is maintained between the maximum and minimum permissible levels to prevent unforeseen occurrences (explosions). Therefore, a BMS is a crucial technology for guaranteeing the security of both the battery and user.
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.
