中文摘要

恒流均衡能快速有效缓解电池组的不一致性。本文提出了一种基于LCC多谐振拓扑的组串到单体(String-to-Cell)电池均衡器,采用开环恒流控制。该方案通过共享均衡单元,实现能量从整个电池组向不平衡单体的高效转移。

English Abstract

Constant current equalization can effectively mitigate the inconsistency of battery strings in a fast manner. In this manuscript, a constant current string-to-cell battery equalizer with an open-loop current control is proposed. The equalization scheme is based on LCC multiresonant topology. It utilizes a common equalizer unit shared by each unbalanced cell to transfer energy from the entire strin...
