When a battery pack is designed using multiple cells in series, it is essential to design the system such that the cell voltages are balanced in order to optimize performance and life cycles. Typically, cell balancing is accomplished by means of by-passing some of the cells during the charge or discharge cycles.
By enabling the battery pack to work within safe and efficient factors, battery balancing strategies are used to equalize the voltages and the SOC among the cells. Numerous parameters such as the application’s particular needs, budget restrictions, and required efficiency are responsible for selection of ideal balancing techniques.
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.
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.
Cell balancing is all about the dissipation or movement of energy between cells. The aim being to align them all with respect to state of charge. Aligning the state of charge of all of the cells in a pack will allow the pack to deliver the most energy and power.
A battery pack can be composed of any number of individual batteries organized in either series or parallel configuration with the aim of providing the necessary electrical power to the devices. It is empirical that the efficient functioning of a battery pack is dependent on how optimally the individual cells are balanced.
