Description

Technical Field

[0001] The present invention relates to the field of new energy, and particularly to a fuel cell vehicle with an external hydrogen supply function. Background Art

[0002] Hydrogen energy is a secondary clean energy source, known as the "ultimate energy source in the 21st century", and is also a clean energy source that is being accelerated in development and utilization under the background of carbon peak and carbon neutrality. Hydrogen energy has been widely used in scenarios such as fuel cell vehicles, hydrogen drones, and hydrogen bicycles. With the increase in application scenarios, the inventory of hydrogen-consuming devices has also continued to grow, and situations of difficult hydrogen refueling or emergency hydrogen refueling often occur, such as temporary hydrogen refueling for household hydrogen bicycles and hydrogen drones, and emergency hydrogen refueling for hydrogen vehicles.

[0003] Heavy hydrogen fuel cell vehicles generally have relatively large power and relatively large hydrogen storage capacity, and can be used as a temporary hydrogen source for emergency supply. However, existing hydrogen fuel cell vehicles do not have an external hydrogen supply function and cannot meet the above scenario requirements. Therefore, there is an urgent need for a method or device that can solve the above problems. Summary of the Invention

[0004] The present invention is to solve the above-mentioned deficiencies of the existing technology, and proposes a fuel cell vehicle with a simple structure, ingenious design, reasonable layout, capable of supplying hydrogen to other hydrogen-consuming devices under special circumstances, and capable of externally supplying hydrogen at different pressure levels.

[0005] The technical solution of the present invention is: a fuel cell vehicle with an external hydrogen supply function, including a vehicle body 1, characterized in that: a hydrogen storage bottle group 2 is provided on the vehicle body 1, All hydrogen storage bottles in the hydrogen storage bottle group 2 are connected to a hydrogen main pipe 3. A main pipe pressure sensor 4 is provided on the hydrogen main pipe 3. The hydrogen main pipe 3 is simultaneously connected to a hydrogen refueling pipeline 5 and a hydrogen supply pipeline 6. The end of the hydrogen refueling pipeline 5 is provided with a hydrogen refueling port 7, and a hydrogen refueling port cover 8 is provided in cooperation with the hydrogen refueling port 7. The end of the hydrogen supply pipeline 6 is provided with a hydrogen supply port 9, and a hydrogen supply port cover 10 is provided in cooperation with the hydrogen supply port 9. A one-way valve 11 is provided on the hydrogen refueling pipeline 5. Under the action of the one-way valve 11, hydrogen can only move from the hydrogen refueling port 7 towards the hydrogen storage bottle group. A pressure reducing valve 12, a pressure regulating valve 13, a hydrogen supply pressure sensor 14, and a hydrogen supply valve 15 are provided on the hydrogen supply pipeline 6. The main pipe pressure sensor 4, the pressure regulating valve 13, and the hydrogen supply pressure sensor 14 are all electrically connected to the control system 16. At the same time, the hydrogen supply valve 15 is also electrically connected to the control system 16 through the interlock switch 17, and the interlock switch 17 is located at the hydrogen refueling port 7. When the hydrogen refueling port cover 8 is opened, the interlock switch 17 is in the off state. When the hydrogen refueling port cover 8 is fastened on the hydrogen refueling port 7, the interlock switch 17 is in the connected state.

[0006] The vehicle body 1 is also provided with a human-machine interface 18 and a hydrogen supply switch 19, and both the human-machine interface 18 and the hydrogen supply switch 19 are electrically connected to the control system 16.

[0007] Compared with the prior art, the present invention has the following advantages: This fuel cell vehicle with the function of supplying hydrogen externally has a simple structure, ingenious design, and reasonable layout. It aims at the problem that equipment such as fuel cell vehicles, hydrogen-powered bicycles, and hydrogen-powered drones that need to use hydrogen as a raw material cannot replenish hydrogen energy in time after the hydrogen energy is exhausted. Based on the existing fuel cell vehicle, it is improved to design a gas path system capable of supplying gas externally. It provides hydrogen for hydrogen-consuming equipment in emergency rescue scenarios through an independent hydrogen supply pipeline and a hydrogen supply port. Secondly, it fully considers safety issues and uses an interlock switch to realize the interlock between the hydrogen supply pipeline and the hydrogen refueling pipeline, which can prevent the simultaneous occurrence of the two working states of hydrogen refueling and hydrogen supply, and ensure safety to the greatest extent. It also has mechanisms such as a free pressure regulating valve, a pressure reducing valve, and a pressure sensor on the hydrogen supply pipeline, which can conveniently and quickly control and adjust the pressure of the externally supplied hydrogen, so as to adapt to different hydrogen supply pressure scenarios, with a wide range of applications. And the dual control mode of the hydrogen supply valve and the pressure regulating valve set in the gas path further improves the safety of the operation of this device.

[0008] In summary, it can be said that this fuel cell vehicle has multiple advantages, is particularly suitable for popularization and application in this field, and has a very broad market prospect. Brief Description of the Drawings

[0010] Figure 2 is a block diagram of the system composition of an embodiment of the present invention. Detailed Embodiments

[0011] The following will describe the specific embodiments of the present invention in conjunction with the drawings. As Figure 1 、 Figure 2Shown: A fuel cell vehicle with an external hydrogen supply function, including a vehicle body 1. A hydrogen storage bottle group 2 is provided on the vehicle body 1. The hydrogen storage bottle group 2 supplies hydrogen to the hydrogen fuel cell in the vehicle body 1. When the hydrogen fuel cell works, it generates electrical energy for the vehicle body 1 to use; All the hydrogen storage bottles in the hydrogen storage bottle group 2 are connected to a hydrogen main pipe 3. A main pipe pressure sensor 4 is provided on the hydrogen main pipe 3. The hydrogen main pipe 3 is simultaneously connected to a hydrogen refueling pipeline 5 and a hydrogen supply pipeline 6. The end of the hydrogen refueling pipeline 5 is provided with a hydrogen refueling port 7, and a hydrogen refueling cover 8 is provided to match the hydrogen refueling port 7. The end of the hydrogen supply pipeline 6 is provided with a hydrogen supply port 9, and a hydrogen supply cover 10 is provided to match the hydrogen supply port 9. A check valve 11 is provided on the hydrogen refueling pipeline 5. Under the action of the check valve 11, hydrogen can only move from the hydrogen refueling port 7 towards the hydrogen storage bottle group. A pressure reducing valve 12, a pressure regulating valve 13, a hydrogen supply pressure sensor 14 and a hydrogen supply valve 15 are provided on the hydrogen supply pipeline 6. The main pipe pressure sensor 4, the pressure regulating valve 13 and the hydrogen supply pressure sensor 14 are all electrically connected to a control system 16. At the same time, the hydrogen supply valve 15 is also electrically connected to the control system 16 through an interlock switch 17. The interlock switch 17 is located at the hydrogen refueling port 7. When the hydrogen refueling cover 8 is opened, the interlock switch 17 is in an off state. When the hydrogen refueling cover 8 is buckled on the hydrogen refueling port 7, the interlock switch 17 is in a connected state.

[0012] A human-machine interface 18 and a hydrogen supply switch 19 are also provided on the vehicle body 1. The human-machine interface 18 and the hydrogen supply switch 19 are both electrically connected to the control system 16.

[0013] The working process of the fuel cell vehicle with an external hydrogen supply function according to the embodiment of the present invention is as follows: When the vehicle body 1 operates normally, the hydrogen storage bottles in the hydrogen storage bottle group 4 supply hydrogen to the fuel cell in the vehicle. The fuel cell works to generate electrical energy and provide power for the vehicle body 1. When it is necessary to supply hydrogen to other hydrogen-consuming devices (such as other fuel cell vehicles, hydrogen-powered bicycles or hydrogen-powered drones, etc.), open the hydrogen supply cover 10, connect the hydrogen input pipeline of the hydrogen-consuming device to the hydrogen supply port 9, and then open the hydrogen supply switch 19. After the control system 16 detects that the hydrogen supply switch 19 is opened, it detects whether the vehicle is in a state where it can supply hydrogen externally (such as hydrogen pressure, whether the vehicle is running, etc.). If it is in a state where it can be refueled at this time, it will control the hydrogen supply valve 15 to open, and the hydrogen in the hydrogen storage bottle group 4 will be input into the hydrogen-consuming device through the pipeline, realizing the operation of supplying hydrogen externally (by this device); When the hydrogen filling port cover 8 is opened, the interlock switch 17 is in the off state. Conversely, when the hydrogen filling port cover 8 is closed, the interlock switch 17 is in the connected state. Only when the interlock switch 17 is in the connected state can the control system 16 control the working state of the hydrogen supply valve 15. Otherwise, the hydrogen supply valve 15 remains in the closed state. This design can effectively ensure safety. That is, when the interlock switch 17 is in the connected state and the control system 16 detects that the vehicle is in a state where it can supply hydrogen externally and issues a signal to open the hydrogen supply valve 15, the hydrogen supply valve 15 can be opened to realize the hydrogen supply operation for external hydrogen-using equipment. When the control system 16 detects that the vehicle is in a state where it cannot supply hydrogen externally (such as vehicle abnormalities, abnormal hydrogen pressure, etc.) or when the hydrogen filling port cover 8 is opened in preparation for hydrogen filling, the hydrogen supply valve 15 will close. During the working process, since a check valve 11 is provided on the hydrogen filling pipeline 5, hydrogen leakage from the hydrogen filling pipeline 5 can be prevented. During the external hydrogen supply process, the control system 16 can monitor the air pressures in the hydrogen main pipe 3 and the hydrogen supply pipeline 6 in real time through the main pipe pressure sensor 4 and the hydrogen supply pressure sensor 14, and at the same time, the output pressure of the hydrogen supply pipeline 6 can be adjusted by controlling the pressure regulating valve 13. Preferably, the user can set various parameters of the system by operating the equipment at the man-machine interface 13.
