When cells have uneven voltages, it can lead to overcharging, undercharging, and reduced battery life. Equalizers prevent these imbalances by transferring charge from high voltage cells to low voltage cells, maintaining an optimal voltage level throughout the pack. There are two primary types of lithium battery equalizers: active and passive.
Battery pack size and configuration: Larger packs with more cells require more powerful equalizers. – Voltage difference between cells: Equalizers with higher voltage handling capabilities are needed for packs with significant voltage imbalances.
The goal of equalization is to increase the battery pack’s consistency as well as the battery pack’s real capacity. The higher the equalization efficiency, the shorter the battery equalization time. The balancing goal can be formulated as: where represents the SOC of the ith battery, the battery pack has 2 n batteries in total, .
Although this kind of equalization strategies has simple system structure and high reliability, its several shortcomings, including poor equalization efficiency, long equalization time and high heat generation (Wang et al., 2022), still motivate researchers to explore more ideal equalization strategy for battery pack continuously.
At present, the common lithium-ion battery equalization methods can be divided into two categories: passive equalization and active equalization. Passive equalization is the earliest and most widely used method.
