The invention relates to a vehicle-mounted multi-liquid hydrogen bottle parallel output supply system which comprises at least two liquid hydrogen bottles horizontally arranged in parallel; the liquid hydrogen vaporization pressurization mechanism is suitable for vaporizing the liquid hydrogen at the second outlet of the corresponding liquid hydrogen bottle, balancing the hydrogen formed after vaporization through a pressurization gas inlet and then conveying the hydrogen into the liquid hydrogen bottle so as to increase the air pressure in the liquid hydrogen bottle and provide power for conveying of the liquid hydrogen; the liquid hydrogen conveying mechanism comprises a liquid outlet pressure balancing assembly which is used for interconnecting the first outlets of the liquid hydrogen bottles and is suitable for balancing the pressure of the liquid hydrogen discharged from the first outlets at the bottoms of the multiple liquid hydrogen bottles, and the liquid outlet pressure balancing assembly is used for balancing the pressure of the liquid hydrogen discharged from the first outlets at the bottoms of the multiple liquid hydrogen bottles; the device has the advantages that the liquid levels of the liquid hydrogen bottles are kept the same under the conditions that the liquid level heights of the liquid hydrogen bottles are different in road conditions, the shapes of the liquid hydrogen bottles have machining deviation and the like, the liquid levels are lowered in a balanced mode at the moment, and the situation that one liquid hydrogen bottle consumes light first and the other liquid hydrogen bottle has much liquid hydrogen and entrained gas is reduced.
本发明涉及一种车载多液氢瓶并联输出供应系统,包括:至少两个液氢瓶,至少两个液氢瓶卧式并联设置;液氢汽化增压机构,适于对对应的液氢瓶第二出口处的液氢进行汽化并且将气化后形成的氢气通过增压气入口平衡好后输送到液氢瓶内以增大液氢瓶内部的气压,为液氢的输送提供动力;液氢输送机构,所述液氢输送机构包括:出液压力平衡组件,将每个液氢瓶的第一出口互联,适于平衡多个液氢瓶底部第一出口排出的液氢的压力,本发明具有使得每个液氢瓶的液位高度在不同路况、液氢瓶形状存在加工偏差等情况下保持液氢瓶液位具有相同的高度,此时液位下降平衡,减少了出现一个液氢瓶先耗光另一个液氢瓶还存在较多液氢和夹气情况的效果。
