中文摘要：

对1MW磷酸铁锂（LiFePO4）锂离子储能电池进行放电、充电均衡。均衡后，单体电池的电压差减小，电池组的直流侧电压差、荷电态（SOC）差均减小。放电、充电均衡后，单体电池的电压差分别为0．011V、0．013V；电池组的直流侧电压差为0．7V、1．2V；电池组的SOC差均为8％。

英文摘要：

Discharge and charge equalization were taken to the 1 MW lithium iron phosphate（LiFeP04） energy storage Li-ion battery. After equalization,cell voltage difference reduced,direct current （DC） voltage difference of battery assembly and the state of charge （SOC） difference were reduced. After discharge and charge equalization, cell voltage difference was 0. 011 V and 0.013 V, respectively; DC voltage difference of battery assembly was 0.7 V and 1.2 V,respectively; SOC differences were both 8%.
