摘要:

对磷酸铁锂电芯、电池模组和电池簇充放电数据进行研究,提出了磷酸铁锂预制舱储能系统荷电状态(SOC)安全区域,即为充放电过程中电池最大压差变化缓慢区。经分析,SOC安全区域与电芯电压变化缓慢区基本重合,为预制舱式储能系统安全运行提供了依据。

关键词: 电芯, 储能系统, 最大电压差, 荷电状态

Abstract:

The data of charge and discharge of lithium iron phosphate cell,module and battery cluster are discussed and analyzed.The safe region of state of charge (SOC) for the energy storage system of lithium iron phosphate prefabricated cabin is the slow region of the maximum voltage difference during charging and discharging,and it coincides with the slow region of the voltage change of a battery.It provides the basis for the safety operation of the prefabricated cabin energy storage system.

Key words: battery cluster, energy storage system, maximum voltage difference, SOC
