储能电站电池标准与测试探讨

Study on standards and testing of battery in energy storage power station

大规模储能系统已经成为保证电力系统可靠供电的一个重要手段,储能电池是储能系统的核心技术。梳理了现有储能电池相关标准,归纳了储能电站电池电气性能测试项目,并对实际测试中存在的问题进行剖析,以电池充放电试验温度和单体一致性为例,说明了储能电池电气性能测试方法仍有待进一步的标准化。为锂离子储能电池电气性能测试标准提供参考。

Large-scale energy storage system has become an important method to ensure reliable power supply in power system,in which energy storage battery is the key technology.The existing standards of battery in energy storage system were listed,and battery electrical performance testing items were also introduced.Then the problems in actual battery testing process were also analyzed.Finally,results of battery temperature and cell consistency during battery charge and discharge testing process were set as an example,which showed that battery electrical performance testing method in energy storage systems needed further standardized,and provided a reference for the standard and testing of lithium ion battery in energy storage systems.
