[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 3 A power system 100 of a vehicle according to an embodiment of the present invention is described.

[0030] like Figure 1 and Figure 2 As shown, the power system 100 according to the embodiment of the present utility model includes: a hydrogen storage container 10 and a power battery 12 .

[0031] The hydrogen storage container 10 is used to store hydrogen and is arranged along the width direction of the vehicle (i.e. Figure 1The hydrogen storage container 10 is located on one side of the mounting frame 80 of the vehicle, and the power battery 12 is located on the other side of the mounting frame 80, and both the hydrogen storage container 10 and the power battery 12 are connected to the mounting frame 80.

[0032] The hydrogen storage container 10 can store compressed hydrogen for use in the vehicle, and the hydrogen storage container 10 can store compressed hydrogen for use in the vehicle. Figure 1 The hydrogen storage container 10 and the power battery 12 are respectively arranged on both sides of the mounting frame 80.

[0033] The hydrogen storage container 10 is used to store hydrogen. In some embodiments of the present application, the hydrogen storage container 10 is a high-pressure gas cylinder wound with carbon fiber, and the gas cylinder is a single-mouth bottle. Figure 1 The hydrogen storage container 10 and the power battery 12 are arranged on both sides of the mounting frame 80. That is to say, the hydrogen storage container 10, the mounting frame 80 and the power battery 12 are arranged along the width direction of the vehicle (i.e. Figure 1 The Y direction as shown) are arranged in sequence.

[0034] The hydrogen storage container 10 is connected to the mounting frame 80, and the connection method between the hydrogen storage container 10 and the mounting frame 80 may be, but not limited to, welding, bolt connection, etc. As some embodiments of the present application, the hydrogen storage container 10 is connected to the mounting frame 80 through a first connection bracket. The power battery 12 is connected to the mounting frame 80, and the connection method between the power battery 12 and the mounting frame 80 may be, but not limited to, welding, bolt connection, etc. As some embodiments of the present application, the power battery 12 is connected to the mounting frame 80 through a second connection bracket.

[0035] As some embodiments of the present application, the number of hydrogen storage containers 10 is one. It is understandable that if the number of hydrogen storage containers 10 is two, the two hydrogen storage containers 10 need to be arranged on both sides of the frame. This arrangement occupies most of the space of the chassis of the vehicle, resulting in that the fuel cell 70 can only be placed in the middle of the frame in the vehicle arrangement link, and can only be selected from a limited number of schemes based on the boundaries of the fuel cell, which seriously limits the selection of the fuel cell 70. Moreover, this arrangement causes the distribution unit 11 to be arranged at the rear of the frame, thereby requiring a longer high-voltage wire harness to be connected to the power battery 12, the drive motor 13, and the fuel cell 70, which not only seriously increases the difficulty of the overall arrangement of the vehicle, but also brings about problems such as insufficient utilization of the chassis space and difficulty in arranging other systems. By adopting a single hydrogen storage container 10 with a large volume, the space of the chassis of the vehicle can be saved, so that the fuel cell 70 can have a variety of selectable forms, and the distribution unit 11 can be arranged in a more reasonable position, which is conducive to reducing the length of the high-voltage wire harness, thereby reducing the difficulty of the overall arrangement of the vehicle and increasing the space utilization rate of the chassis space.

[0036] Moreover, by arranging the hydrogen storage container 10 and the power battery 12 on both sides of the mounting frame 80, the arrangement positions of the hydrogen storage container 10, the power battery 12 and the mounting frame 80 can be reasonable, thereby improving space utilization.

[0037] Therefore, by arranging the hydrogen storage container 10 and the power battery 12 on both sides of the mounting frame 80, compared with the prior art, the layout positions of the hydrogen storage container 10 and the power battery 12 can be made reasonable, the selection options of the power battery 12 can be increased, and the difficulty of selecting the power battery 12 can be reduced. Moreover, by arranging the hydrogen storage container 10 and the power battery 12 on both sides of the mounting frame 80, space can be saved, space utilization can be improved, and it is beneficial to reduce the difficulty of arranging other components, reduce the difficulty of arranging the power system 100, and facilitate the compact design of the vehicle.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the power system 100 of the vehicle further includes: a power distribution unit 11, which is located inside the mounting frame 80 and connected to the mounting frame 80, and is arranged along the width direction of the vehicle (i.e. Figure 1 In the Y direction shown in the figure), the orthographic projections of the hydrogen storage container 10, the power battery 12, and the power distribution unit 11 have overlapping areas.

[0039] The power distribution unit 11 is disposed inside the mounting frame 80, and the power distribution unit 11 is connected to the mounting frame 80. The connection method between the power distribution unit 11 and the mounting frame 80 may be, but is not limited to, welding, bolt connection, etc. As some embodiments of the present application, the power distribution unit 11 is connected to the mounting frame 80 via a third connecting bracket.

[0040] Along the width direction of the vehicle (i.e. Figure 1 The orthographic projections of the hydrogen storage container 10, the power battery 12, and the power distribution unit 11 have an overlapping area. Specifically, a plane is set, which is parallel to the width direction of the vehicle (i.e. Figure 1 In other words, the normal of the plane is perpendicular to the width direction of the vehicle (i.e. Figure 1 The hydrogen storage container 10, the power battery 12, and the power distribution unit 11 have overlapping areas in their orthographic projections on the plane.

[0041] As some embodiments of the present application, along the width direction of the vehicle (ie Figure 1 The hydrogen storage container 10 is arranged on the left side of the mounting frame 80, the power battery 12 is arranged on the right side of the mounting frame 80, and the distribution unit 11 is arranged on the inner side of the mounting frame 80 so that the distribution unit 11 is located between the mounting frame 80 and the power battery 12.

[0042] As some embodiments of the present application, the power distribution unit 11 can be used to distribute power to various electrical devices and the power battery 12.

[0043] The power distribution unit 11 is arranged inside the mounting frame 80 and connected to the mounting frame 80, and the hydrogen storage container 10, the power battery 12, and the power distribution unit 11 are arranged along the width direction of the vehicle (i.e. Figure 1 The orthographic projection in the Y direction (as shown) has an overlapping area, which can make the arrangement positions of the components in the power system 100 reasonable and reduce the difficulty of arranging the power system 100.

[0044] In some embodiments of the present invention, Figure 2 As shown, the vehicle power system 100 also includes a fuel cell 70, which is arranged along the length direction of the vehicle (i.e. Figure 1 The fuel cell 70 is arranged on one side of the power distribution unit 11, and the length direction of the vehicle (i.e. Figure 1 The X direction shown) and the width direction of the vehicle (i.e. Figure 1 The X direction shown is perpendicular to the

[0045] The vehicle power system 100 further includes a fuel cell 70, which is arranged along the length direction of the vehicle (i.e. Figure 1 The fuel cell 70 can be arranged on any side of the power distribution unit 11 (X direction as shown).

[0046] As some embodiments of the present application, along the length direction of the vehicle (i.e. Figure 1 The fuel cell 70 is disposed on a side of the power distribution unit 11 close to the front of the vehicle.

[0047] As some embodiments of the present application, along the length direction of the vehicle (i.e. Figure 1 The fuel cell 70 is disposed on a side of the power distribution unit 11 close to the rear of the vehicle.

[0048] Such an arrangement can make the fuel cell 70 arranged at a reasonable position, thereby reducing the difficulty of arranging the power system 100 .

[0049] In some embodiments of the present invention, Figure 2 As shown, the vehicle power system 100 also includes: a drive motor 13, along the length direction of the vehicle (ie Figure 1 The driving motor 13 is arranged on the other side of the power distribution unit 11.

[0050] The vehicle power system 100 further includes a drive motor 13, which is arranged along the length direction of the vehicle (i.e. Figure 1 The fuel cell 70 is disposed on one side of the power distribution unit 11, and the drive motor 13 is disposed on the other side of the power distribution unit 11.

[0051] As some embodiments of the present application, along the length direction of the vehicle (i.e. Figure 1 The driving motor 13 is arranged on the side of the power distribution unit 11 close to the front of the vehicle, and the fuel cell 70 is arranged on the side of the power distribution unit 11 close to the rear of the vehicle.

[0052] As some embodiments of the present application, Figure 2 As shown, along the length direction of the vehicle (i.e. Figure 1 The driving motor 13 is arranged on the side of the power distribution unit 11 close to the rear of the vehicle, and the fuel cell 70 is arranged on the side of the power distribution unit 11 close to the front of the vehicle.

[0053] By arranging the fuel cell 70 and the drive motor 13 on both sides of the power distribution unit 11 respectively, the arrangement positions of the components in the power system 100 can be reasonable, and the layout difficulty of the power system 100 can be reduced.

[0054] In some embodiments of the utility model, the power system 100 of the vehicle also includes: a combination valve 20, the hydrogen storage container 10 is connected to the combination valve 20, and the combination valve 20 is suitable for being connected to the hydrogenation device 60 and the fuel cell 70; the combination valve 20 includes: a first solenoid valve, a second solenoid valve and a pressure reducing valve, the second solenoid valve and the pressure reducing valve are connected in series, the first solenoid valve is used to control the on-off of the hydrogen storage container 10 and the hydrogenation device 60, and the second solenoid valve is used to control the on-off of the hydrogen storage container 10 and the fuel cell 70.

[0055] The hydrogen storage container 10 may store compressed hydrogen for use in the vehicle. The combination valve 20 is connected to the hydrogen storage container 10, and the combination valve 20 can be connected to the hydrogenation device 60 and the fuel cell 70. The combination valve 20 can control the on-off of the hydrogen storage container 10 and the hydrogenation device 60, and the combination valve 20 can control the on-off of the hydrogen storage container 10 and the fuel cell 70.

[0056] When it is necessary to add hydrogen to the hydrogen storage container 10, the combined valve 20 is controlled to operate so that the hydrogen storage container 10 is connected to the hydrogenation device 60, and the hydrogenation device 60 can replenish hydrogen to the hydrogen storage container 10 through the combined valve 20. When it is necessary to provide hydrogen to the fuel cell 70, the combined valve 20 is controlled to operate so that the hydrogen storage container 10 is connected to the fuel cell 70, and the hydrogen storage container 10 can provide hydrogen to the fuel cell 70 through the combined valve 20.

[0057] The combination valve 20 may include a first solenoid valve, a second solenoid valve and a pressure reducing valve, wherein the first solenoid valve may be connected between the hydrogen storage container 10 and the hydrogenation device 60, and the first solenoid valve is used to control the on-off of the hydrogen storage container 10 and the hydrogenation device 60. The second solenoid valve and the pressure reducing valve are arranged in series, and the second solenoid valve and the pressure reducing valve may be connected between the hydrogen storage container 10 and the fuel cell 70, and the second solenoid valve is used to control the on-off of the hydrogen storage container 10 and the fuel cell 70, and the pressure reducing valve is used to reduce the pressure of the hydrogen flowing out of the hydrogen storage container 10, so that the pressure value of the hydrogen flowing into the fuel cell 70 is maintained within a preset range.

[0058] As some embodiments of the present application, the pressure reducing valve may be arranged upstream of the second solenoid valve, that is, the hydrogen flowing out of the hydrogen storage container 10 first flows through the pressure reducing valve and then flows through the second solenoid valve. As some embodiments of the present application, the second solenoid valve may be arranged upstream of the pressure reducing valve, that is, the hydrogen flowing out of the hydrogen storage container 10 first flows through the second solenoid valve and then flows through the pressure reducing valve.

[0059] As some embodiments of the present application, Figure 3 As shown, the power system 100 may further include a filter 50. The filter 50 may be disposed upstream of the combination valve 20, and the filter 50 may be disposed in series with the first solenoid valve. When hydrogen needs to be added to the hydrogen storage container 10, the hydrogen output by the hydrogenation device 60 will first pass through the filter 50, and then enter the hydrogen storage container 10 through the first solenoid valve of the combination valve 20, so that the hydrogen filled in the hydrogen storage container 10 can be filtered so that the hydrogen in the hydrogen storage container 10 meets the use standard of the fuel cell 70.

[0060] It can be understood that by integrating the first solenoid valve, the second solenoid valve and the pressure reducing valve into the combination valve 20, the difficulty of assembling the power system 100 can be reduced. Moreover, by integrating the first solenoid valve, the second solenoid valve and the pressure reducing valve together, the combination valve 20 can be integrated with the control function of the power system 100, and the combination valve 20 can be directly controlled by the vehicle controller or the fuel cell system controller of the vehicle, thereby omitting a separate power system controller and simplifying the architecture of the power system 100.

[0061] As some embodiments of the present application, the number of hydrogen storage containers 10 is one. It can be understood that the number of combination valves 20 and the number of hydrogen storage containers 10 can be in a one-to-one correspondence. By setting the number of hydrogen storage containers 10 to one, the number of combination valves 20 can be reduced, which is beneficial to reduce the weight and cost of the power system 100.

[0062] By setting the combination valve 20, the first solenoid valve, the second solenoid valve and the pressure reducing valve can be integrated together, so as to reduce the number of single valve structures of the power system 100 and reduce the difficulty of assembling the power system 100. Moreover, by integrating the first solenoid valve, the second solenoid valve and the pressure reducing valve, it is helpful to simplify the architecture of the power system 100 and reduce the production cost of the power system 100.

[0063] In some embodiments of the present invention, Figure 3 As shown, the combination valve 20 further includes: a relief valve. The relief valve is arranged in series with the second solenoid valve.

[0064] Among them, the second solenoid valve and the pressure reducing valve can be connected between the hydrogen storage container 10 and the fuel cell 70. The second solenoid valve is used to control the on-off of the hydrogen storage container 10 and the fuel cell 70. The overflow valve is arranged in series with the second solenoid valve. It should be noted that the overflow valve is used to limit the flow. When a traffic accident occurs to the vehicle and causes a pipeline rupture, the overflow valve can automatically disconnect the hydrogen storage container 10 and the fuel cell 70 to prevent a large amount of hydrogen leakage, thereby improving the reliability of the power system 100 and helping to reduce the probability of safety accidents due to a large amount of hydrogen leakage.

[0065] Furthermore, by integrating the overflow valve into the combination valve 20 , the architecture of the power system 100 can be further simplified.

[0066] As some embodiments of the present application, the overflow valve can be arranged upstream of the second solenoid valve, that is, the hydrogen flowing out of the hydrogen storage container 10 first flows through the overflow valve and then flows through the second solenoid valve. As some embodiments of the present application, the second solenoid valve can be arranged upstream of the overflow valve, that is, the hydrogen flowing out of the hydrogen storage container 10 first flows through the second solenoid valve and then flows through the overflow valve.

[0067] As some embodiments of the present application, the relief valve may be disposed upstream of the pressure reducing valve, or the relief valve may be disposed downstream of the pressure reducing valve.

[0068] In some embodiments of the present invention, Figure 3 As shown, the combination valve 20 further includes: a first pressure relief valve. The first pressure relief valve is connected between the hydrogen storage container 10 and the first exhaust pipe 30 , and the first exhaust pipe 30 is communicated with the first exhaust port 31 .

[0069] Among them, a first pressure relief valve may be connected between the hydrogen storage container 10 and the first exhaust pipe 30. As some embodiments of the present application, the first pressure relief valve may be constructed as a PRD valve. The first pressure relief valve may be composed of a fusible alloy. When an accident such as a fire or collision causes the hydrogen pressure and hydrogen temperature in the hydrogen storage container 10 to exceed the set value, the fusible alloy is disconnected to automatically open the first pressure relief valve. The hydrogen in the hydrogen storage container 10 may pass through the first pressure relief valve and the first exhaust pipe 30 in sequence and be discharged from the first exhaust port 31. That is to say, by providing the first pressure relief valve, exhaust and pressure relief can be performed quickly and automatically in the event of an accident, thereby facilitating the use safety of the power system 100. In addition, by integrating the first pressure relief valve into the combination valve 20, it is beneficial to further simplify the architecture of the power system 100.

[0070] As some embodiments of the present application, a flame arrester may be provided at the first exhaust port 31 , and by providing the flame arrester, the occurrence of a backfire accident may be prevented.

[0071] In some embodiments of the present invention, Figure 3 As shown, the combination valve 20 has a first flow path, a second flow path and a third flow path connected in parallel, the second solenoid valve and the pressure reducing valve are arranged in the first flow path, the first solenoid valve is arranged in the second flow path, and the first pressure relief valve is arranged in the third flow path.

[0072] It is understandable that the combination valve 20 has three parallel flow paths at the same time. Various valves are respectively provided on the three flow paths to play different roles. Among them, the second solenoid valve and the pressure reducing valve are arranged in the first flow path, and the first flow path is used to connect the hydrogen storage container 10 and the fuel cell 70. The first solenoid valve is arranged in the second flow path, and the second flow path is used to connect the hydrogen storage container 10 and the hydrogenation device 60. The first pressure relief valve is arranged in the third flow path, and the third flow path is used to connect the hydrogen storage container 10 and the first exhaust port 31.

[0073] Such an arrangement can make the structure of the combination valve 20 reasonable, and can connect the hydrogen storage container 10 with the fuel cell 70, the hydrogenation device 60, and the first exhaust port 31 respectively, so as to control the on-off of the hydrogen storage container 10 and the fuel cell 70, the on-off of the hydrogen storage container 10 and the hydrogenation device 60, and the on-off of the hydrogen storage container 10 and the first exhaust port 31 respectively, and can avoid mutual interference between the fuel cell 70, the hydrogenation device 60, and the first exhaust port 31.

[0074] In some embodiments of the present utility model, the combination valve 20 further includes: a temperature sensor and a pressure sensor. The temperature sensor is used to detect the temperature of hydrogen, and the pressure sensor is used to detect the pressure of hydrogen.

[0075] It is understandable that the combination valve 20 may further include a temperature sensor and a pressure sensor. When hydrogen passes through the combination valve 20, the temperature sensor can detect the temperature of the hydrogen passing through the combination valve 20, and the pressure sensor can detect the pressure of the hydrogen passing through the combination valve 20. As some embodiments of the present application, when the hydrogenation device 60 replenishes hydrogen to the hydrogen storage container 10, the temperature sensor and the pressure sensor may be used to detect the temperature and pressure of the hydrogen from the hydrogenation device 60, respectively, and when the hydrogen storage container 10 provides hydrogen to the fuel cell 70, the temperature sensor and the pressure sensor may be used to detect the temperature and pressure of the hydrogen from the hydrogen storage container 10, respectively.

[0076] As some embodiments of the present application, the data detected by the temperature sensor and the pressure sensor can be fed back to the vehicle controller or the fuel cell system controller of the vehicle, so as to promptly remind the user when the hydrogen temperature and hydrogen pressure are abnormal, thereby helping to improve the safety of the use of the power system 100. In addition, by integrating the temperature sensor and the pressure sensor into the combination valve 20, it is helpful to further simplify the architecture of the power system 100, which is conducive to further reducing the production cost of the power system 100, and the difficulty of assembling the power system 100 can be further reduced.

[0077] In some embodiments of the present invention, the combination valve 20 further includes a one-way valve. The one-way valve is connected to the first solenoid valve and is located upstream of the first solenoid valve. The one-way valve is one-way from the first solenoid valve to the hydrogen storage container 10 .

[0078] Specifically, when hydrogen needs to be added to the hydrogen storage container 10, since the one-way valve is one-way connected from the first solenoid valve to the hydrogen storage container 10, the hydrogen output by the hydrogenation device 60 will first pass through the one-way valve and then pass through the first solenoid valve. By setting the one-way valve, the hydrogenation device 60 can not only allow hydrogen to be introduced into the hydrogen storage container 10, but also prevent the hydrogen in the hydrogen storage container 10 from leaking out, thereby helping to improve the reliability of the power system 100. In addition, by integrating the one-way valve into the combination valve 20, it is helpful to further simplify the architecture of the power system 100.

[0079] In some embodiments of the present invention, Figure 3 As shown, the power system 100 further includes: a second pressure relief valve 40 . The second pressure relief valve 40 is connected between the hydrogen storage container 10 and a second exhaust pipe 41 , and the second exhaust pipe 41 is in communication with a second exhaust port 42 .

[0080] Among them, a second pressure relief valve 40 can be connected between the hydrogen storage container 10 and the second exhaust pipe 41. As some embodiments of the present application, the second pressure relief valve 40 can be constructed as a PRD valve. The second pressure relief valve 40 can be composed of a fusible alloy. When an accident such as a fire or a collision causes the hydrogen pressure and the hydrogen temperature in the hydrogen storage container 10 to exceed the set value, the fusible alloy is disconnected to allow the second pressure relief valve 40 to open automatically. The hydrogen in the hydrogen storage container 10 can pass through the second pressure relief valve 40 and the second exhaust pipe 41 in sequence and be discharged from the second exhaust port 42. That is to say, by providing the second pressure relief valve 40, exhaust and pressure relief can be performed quickly and automatically in the event of an accident, which is beneficial to improving the safety of the power system 100.

[0081] As some embodiments of the present application, a flame arrester may be provided at the second exhaust port 42. By providing the flame arrester, the occurrence of a flashback accident may be prevented. Figure 3 As shown, the hydrogen storage container 10 can be constructed as a hydrogen storage bottle. The hydrogen storage container 10 can have two opposite ends, one of which is the bottle mouth of the hydrogen storage container 10.
