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.
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.
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.
needs two key things to balance a battery pack correctly: balancing circuitry and balancing algorithms. While a few methods exist to implement balancing circuitry, they all rely on balancing algorithms to know which cells to balance and when. So far, we have been assuming that the BMS knows the SoC and the amount of energy in each series cell.
A deep knowledge of both the chosen balancing approach and the overall system structure of the BMS is needed for combining battery balancing techniques into a BMS. It consists of accurate control strategies, careful design, strong safety mechanisms, and complete diagnostics and maintenance methods.
