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.
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, .
A layered battery equalization method is proposed, which reduces the calculation difficulty of the equalization current by layered equalization of the batteries in the group and calculates the equalization current in real-time according to the state of the batteries in the group.
The entire battery pack is divided into several modules to improve the equalization speed . This equalizer introduces intra- and inter-module equalization. In intra-module equalization, all the cells in a module are equalized as in a conventional equalizer. This equalizer allows module-to-module equalization.
Good performance of the proposed equalization strategy is verified by various experiments. The inconsistency in large-scale series-connected lithium battery pack significantly impacts the usable capacity of the battery pack and raises the likelihood of safety risks. In this paper, an equalizer based on Buck–Boost converter is utilized.
