摘要

提出了一种新的基于变换器的有源平衡拓扑结构。该均衡器拓扑由单个非隔离DC/DC转换器和通过控制开关的单元间功率路由组成，这些开关作为功率多路复用器工作。介绍了均衡器的设计和控制策略。通过仿真对其性能进行了评价。均衡器平衡五个单体电池的不平衡电池组，补偿初始SOC偏差并从那时起保持电池组平衡。分析了4种电池参数对SOC发散的影响。

Active Battery Balancing Via a Switched DC/DC Converter: Description and Performance Analysis

This paper presents a new converter-based active balancing topology. This equalizer topology consists of a single non-isolated DC/DC converter and cell-to-cell power routing via controlled switches, which are operated as power multiplexers. The design and control strategy of the equalizer are explained. Its performance is assessed in simulation. The equalizer balances an imbalanced battery pack of five monobloc batteries, compensating the initial SOC deviations and keeping the pack balanced from then on. The influence of four battery parameters in SOC divergence is analyzed.
