AI Technical Summary

Problems solved by technology

Intense pre-cooling gas can cause problems with freezing of connected grease nipples
Moreover, the temperature of the hydrogen in the vehicle's on-board gas storage tank cannot be controlled
The temperature of the hydrogen needs to be low enough to allow the gas storage tank to achieve the desired filling rate, but when the gas storage tank is only partially empty, the temperature of the hydrogen is still low
When the hydrogen temperature rises after filling, the pressure in the gas storage tank will increase, which will cause the gas to flow out of the on-board storage tank through the safety valve, thereby losing valuable gas

Embodiment Construction

[0044] In the drawings, the same components or components with similar functions are denoted by the same reference numerals.

[0045] In the present description and claims, the term "container" includes all types of storage containers that hold hydrogen gas or fluid in liquid form at a pressure different from the ambient pressure.

[0046] figure 1 It is a schematic diagram of a container 1, such as a hydrogen fuel storage tank or a hydrogen cylinder installed in a vehicle. The container 1 has a first port 2 for gas to pass through and a second port 3 for liquid to pass through, wherein the second port 3 is connected to the The first port 2 is separated from which, in the embodiment shown, the second port 3 is separated by a large or remote distance.

[0047] like figure 1 As shown, when the container 1 is placed in the working position, the second port 3 terminates in the container 1 , preferably below the end of the first port 2 located in the container 1 . The two ports ...

Abstract

The invention discloses a method and a filling device for filling hydrogen gas into a container (1) having a first port (2) for the passage of hydrogen gas and a second port (3) for the passage of liquid, wherein the The second port (3) is separated from the first port (2). In the first stage, by applying pressure to the hydraulic fluid, the hydraulic fluid flows into the container (1) through the second port (3), so that the hydraulic fluid in the container (1) generates a hydrostatic pressure with a predetermined value. In the second stage, the hydrogen gas flows through the first port (2) by controlling the pressure difference relative to the existing pressure in the vessel (1) to control the expansion of the hydrogen gas, thereby controlling the temperature in the vessel (1) In this container (1), to fill hydrogen to this container (1). Thus, the hydraulic fluid is removed from the container (1 ) via the second port (3).

Description

technical field [0001] The present invention relates to a method of filling hydrogen into a container, such as a vehicle fuel storage tank, having a first port for passage of gas and a second port for passage of liquid, wherein the second port is connected to the The first port is separated, in particular the second port is separated from the first port by a large or remote distance. Background technique [0002] US patent specification US-B1-6,439,278 discloses a compressed natural gas filling system comprising rows of connected elongated cylinders for delivering compressed natural gas to a filling station. Each cylinder has separate ports at one end for CNG and hydraulic fluid that does not mix easily with CNG. A hydraulic fluid port comprises a tube within a cylinder that leads from one end to a point adjacent the other end of the cylinder. In use, hydraulic fluid is introduced into the cylinder through the hydraulic fluid port under pressure, forcing the compressed nat...
