摘要
为了实现锂离子电池储能系统的有效能量管控,首先对由大量锂离子电池组成的储能系统的组织结构设计进行了研究,提出了分组、分层次、自治的设计方法;然后针对设计的电池储能系统提出了一种基于电池荷电状态(SOC)的充电管理策略,以提高其充电效率,延长其使用寿命,保证其长期稳定运行。实验结果表明,该管理策略可以有效提高锂离子电池储能系统的充电效率。
In order to achieve the reasonable energy management for a lithium-ion battery energy storage system. First- ly, the organizational structure of the energy storage system composed by a large number of lithium-ion batteries is stud- ied. Then, a design method is proposed in this paper, which divides the batteries into groups and different levels, and what' s more, the batteries exercise autonomy themselves. After that, in view of this designed battery energy storage system, a charging management strategy based on the battery state of charge (SOC) is proposed to improve its charging efficiency, and extend its life and ensure its long-term stable operation as well. The experimental result shows that the management strategy can improve the charging efficiency of the lithium-ion battery energy storage system
