电网侧锂电池储能均衡方式分析

摘要

在电网侧大规模储能应用中, 锂离子电池储能系统配置容量高, 单体电池间的不一致性将严重影响储能电站的运行效果.大规模储能对均衡管理技术提出了更高要求.对近三年锂离子电池的均衡方式进行分析, 提出大规模储能系统均衡控制方法的发展方向.%In the large-scale energy storage application on the grid side, the lithium-ion battery energy storage system has a high configuration capacity, and the inconsistency between the single cells will affect the operation effect of the energy storage power station seriously.Large-scale energy storage puts higher demands on equalization technology.At present, there is few equalization technology for energy storage systems.This paper aims to analyze the equilibrium technology of lithium ion batteries in the past three years and proposed the development direction of equilibrium control methods of large-scale energy storage systems.
