The invention belongs to the technical field of flow batteries, and particularly relates to a nitrogen purging method for a flow battery. The method comprises the following steps: step 1, providing a vanadium battery system and a nitrogen purging mobile vehicle, and step 2, detachably connecting a vanadium battery module needing nitrogen purging with the nitrogen purging mobile vehicle to realize nitrogen purging. The invention discloses a flow battery nitrogen purging mobile vehicle, and when a flow battery is used in a large-scale energy storage power station and nitrogen purging needs to be carried out on an electrolyte tank, the nitrogen purging mobile vehicle can be adopted to carry out purging through a reserved nitrogen pipeline. Therefore, a plurality of vanadium battery energy storage systems can share one set of nitrogen purging mobile vehicle and only purge at a specific time period. The complexity of the system is greatly simplified, the occupied area is reduced, and the cost is saved.

    本发明属于液流电池技术领域,具体涉及一种液流电池氮气吹扫方法。所述方法包括如下步骤:步骤1、提供钒电池系统和氮气吹扫移动车,步骤2、将需要进行氮气吹扫的钒电池模组与氮气吹扫移动车可拆卸连接,实现氮气吹扫。本申请公开一种液流电池氮气吹扫移动车,当在大规模储能电站中使用液流电池,需要对电解液罐进行氮气吹扫时,可以采用本申请的氮气吹扫移动车,通过预留的氮气管路进行吹扫。因此可以多个钒电池储能系统共用一套氮气吹扫移动车,只在特定时段吹扫。这大大简化系统复杂程度,减小了占地面积,节约了成本。
