Comparison and evaluation of the various battery cell balancing techniques based on performance enhancement. A two-stage charging approach based on the active balance circuit. Range extension benefits and increase in energy. The heat dissipation issue caused by the huge balancing current is also resolved.
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
One of the most important parameters of estimation the performance of battery cell balancing is the equalization time. Other parameters such as power efficiency and loss are related to the balancing speed.
To understand this algorithm’s working, the SOC of the battery pack is predetermined in the system. To balance all the cells in the battery pack, the system will learn the SOC of each cell in the battery pack, and it will compare them with the reference cell voltage to balance them.
When the SOCs of B 1 and B 2 stabilize at 34.5% and those of B 3 and B 4 at 64.5%, the control unit then activates switch S6 to transfer energy from the B 3 -B 4 group to the B 1 -B 2 group through L 3, balancing the entire battery pack. This process, as shown in Fig. 15 (a), is completed within 55 s, achieving an overall SOC of 43.5%.
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.
