The invention discloses a cooling liquid filling method and system for a multi-stack fuel cell system and a vehicle, and relates to the technical field of fuel cell systems, and the multi-stack fuel cell system comprises an expansion water tank, a first valve, a second valve, at least one stack, a third valve, a fourth valve and a heater which are connected in sequence, a main water pump is arranged between the expansion water tank and the heater, and a closed loop is formed by connecting the components in sequence. According to the cooling liquid filling method for the multi-stack fuel cell system, a water supplementing valve, vacuumizing equipment, a second valve, an auxiliary water tank, a third valve, an auxiliary water pump and a fourth valve are controlled to be connected or communicated; the fuel cell system can automatically complete water adding and air exhausting operation, and cooling liquid filling is completed; compared with the prior art, the cooling liquid filling method for the multi-stack fuel cell system can realize automatic cooling liquid supplementing work, so that too little cooling liquid in a cooling loop of the fuel cell system is avoided, and the working intensity of daily manual maintenance is reduced.

    本发明公开了一种多电堆燃料电池系统冷却液加注方法及其系统、车辆,涉及燃料电池系统技术领域,一种多电堆燃料电池系统包括依次连接的膨胀水箱、第一阀、第二阀、至少一个电堆、第三阀、第四阀以及加热器,膨胀水箱与加热器之间设有主水泵并将上述依次连接部件组成闭环回路,一种多电堆燃料电池系统冷却液加注方法通过控制补水阀、抽真空设备、第二阀、副水箱、第三阀、辅助水泵、第四阀连接或接通关系,使得燃料电池系统自动完成加水排气操作,完成冷却液加注;本申请中的一种多电堆燃料电池系统冷却液加注方法与现有技术相比,能够实现自动冷却液补充工作,避免燃料电池系统的冷却回路中冷却液过少,降低日常人工维护工作强度。
