锂电池组串联均衡系统研究

Research on the Equilibrium Management of Lithium Batteries Connected in Series

锂电池组串联使用的安全性问题是其在船舶上是否能应用的关键技术之一,锂电池组的不一致性会使电池组中串联充放电时个别电池提前损坏,寿命大大缩短,严重时会出现爆炸等安全问题。本文提出了一种无损的能量转移式电池组均衡方案,并从实验上进行了验证,证明了该方案的可行性和先进性。

The critical technology of applying lithium battery to ship is focused on the safety of batteries connected in series. The imbalance of batteries in series will result in the damage of some batteries of the pile in advance, shortening the battery＇s life sharply, and even bring safety problem such as battery explosion. This paper proposes a lossless energy transfer equalization method, and experimentally verified, and proved the feasibility and advantage of the method.
