锂电池储能舱运行状态信息采集系统研究

Research on information acquisition system of lithium battery energy storage cabin

锂电池储能舱是储能系统的核心部件,内部存放大量电池,一旦发生严重事故极易造成整个锂电池储能舱的烧毁,如无法获取事发时刻系统和电池堆的运行数据,将给事故分析带来困难。本文对锂电池储能舱可能发生的故障及异常情况进行了全面的研究和分析,提出了一种锂电池储能舱运行状态信息采集系统方案,该方案能实时记录运行时的状态信息,并在储能舱发生异常状况时快速启动录波,保存数据为储能系统事故分析提供技术支撑。

Lithium battery energy storage cabin is the core component of the energy storage system,which stores a large number of batteries.Once a serious accident occurs,it is easy to burn the whole battery cabin.If the operation data of the system and battery stack at the time of the accident cannot be obtained,it will bring difficulties to the accident analysis.In this paper,the possible faults and abnormal conditions of lithium battery energy storage cabin are comprehensively studied and analyzed,and a scheme of lithium battery energy storage cabin operation status information acquisition system is proposed.The scheme can record the operation status information in real time,and quickly start the recording when the abnormal conditions occur in the energy storage cabin,save the data,so as to provide technical support for the accident analysis of energy storage system.
