摘要

通过串并联方式组成的兆瓦级储能电站在长期运行过程中，将出现电池单体不一致性的问题。由于电压、温度变化特性可直观反映储能电站电池单体间的不一致性，因此利用储能电池极差电压、累计极差电压、电压标准差、极差温度、累计极差温度等指标来分析储能电站电池单体一致性的统计特性。通过长时间尺度电池单体一致性的统计特性分析，结合储能电池现场运行状况，可及时发现可能存在异常的电池单体，为储能电站健康状态评估提供数据支撑，降低储能电站系统性运行风险。

Abstract

In the long-term operation of MW-level energy storage power stations composed of series and parallel connections

the inconsistency of battery cells will occur. Because the variation characteristics of voltage and temperature can directly reflect the inconsistency between battery cells in energy storage power station

the statistical characteristics of battery cell consistency in energy storage power station were analyzed by using extreme difference voltage

accumulated extreme difference voltage

voltage standard deviation

extreme difference temperature

accumulated extreme difference temperature of energy storage battery. By analyzing the statistical characteristics of the consistency of battery cells on a long-term scale

combined with the on-site operating status of energy storage battery

abnormal battery cells can be found in time

which can provide data support for the health assessment of energy storage power station

and reduce the systematic operation risk of energy storage power station.
