There are some real-world case studies or practical applications of EV manufacturers (BMW i3, Hyundai KONA 2019 and Eco car) implementing advanced battery cell balancing techniques are presented in Table 8.
Battery cell balancing fundamentals Battery cell balancing is an important process in BMS, playing a pivotal role in various applications such as EVs, renewable energy storage, and portable electronics. Its primary objective is to ensure that all individual cells within a battery pack maintain the equal SoC or voltage.
After performing cell balancing, each cell's SoC reaches 60 % (average SoC) which signifies that all cells have reached to same level or balanced. Therefore, SoC balancing is crucial in EV battery pack to increase the usable capacity. Fig. 3. Charge among five cells connected in series before and after SoC balancing.
This is essential because manufacturing discrepancies and variations in cell usage can lead to difference in cell voltage and SoC levels. Without proper balancing, some cells may get overcharged, while others remain undercharged, resulting in inefficiencies and potential damage to the battery pack.
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).
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.
