Based on the above analysis, this paper proposes an active equalization method for series-parallel battery pack based on an inductor. The main contributions are described below. The energy storage device responsible for energy transfer requires only one inductor and the topology is simple and low cost.
7. Conclusion An active equalization method for series-parallel battery pack based on an inductor is proposed, which has the features of simple structure and low cost, and can realize the equalization between any cell in the series-parallel battery pack.
Studies on the equalization of parallel battery pack have also been conducted , , . The literatures , achieve parallel equalization by adding a DC/DC converter for each parallel module, which is not conducive to the size and cost reduction of the equalization system .
Due to the low voltage and capacity of the cells, they must be connected in series and parallel to form a battery pack to meet the application requirements. After forming a battery pack, the inevitable inconsistency between the cells will have a serious impact on its energy utilization and cycle life, and even bring safety hazards , .
The m series battery pack in parallel are named P 1, P 2 …, P m. The n cells and 2 n + 2 MOSFETs in each series battery pack are named B x1, B x2, …, B xn and S x0, S x1, …, S x(2n+1), where x is the serial number of the parallel battery pack (x = 1, 2, …, m). The inductor is named L. Fig. 1.
The topology in has a flexible equalization path, which can transfer energy to the adjacent sides of the cells or battery modules to reduce the equalization time, but it is complex in terms of control due to the different working modes.

Known as series-parallel, it mixes batteries in series and then these sets in parallel. What factors should be considered when choosing between series, parallel, or series-parallel battery configurations? The choice depends on what power is needed. Series works for high voltage needs, parallel for longer power. Series-parallel balances power ...

The results show that the proposed method contribution-based PCA accurately detects the fault in the battery pack and reconstruction-based parallel PCA-KPCA estimate the fault waveform of the faulty battery, which helps to investigate the fault causes. Besides, some types of faults will not cause abnormalities in all parameters of the battery. For example, a …

Abstract: To better evaluate the configuration of battery packs in electric vehicles (EV) in the early design phase, this paper proposes a mathematic model for the simulation of battery packs based on the elementwise calculations of matrices. This model is compatible with the different battery models and has a fast simulation speed.
This combined setup is necessary because relying solely on one method may not meet the power requirements. By combining series and parallel connections, battery packs can be customized to deliver the desired voltage and capacity. For simplicity, battery packs are labeled with abbreviations : "S" for series and "P" for parallel. For example, if a battery pack …
