[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.
[0036] Referring to Figures 1 to 5 as shown, the hydrogen energy power system 10 of the present application includes an on-vehicle hydrogen storage system 100. The on-vehicle hydrogen storage system 100 includes: a hydrogen storage package 300, a direct exhaust pipeline 101, a distributed exhaust pipeline 102, a regulating valve 103, a hydrogen pump 104, a hydrogen storage cylinder 105, a check valve 106, an output pipeline 107, and a pressure gauge 108.
[0037] Among them, the hydrogen storage package 300 is used to store hydrogen; the direct exhaust pipeline 101 is used to guide the exhaust gas of the engine 200 directly out of the vehicle; the divided exhaust pipeline 102 is used to guide the exhaust gas of the engine 200 out of the vehicle after passing through the hydrogen storage package 300; the regulating valve 103 is used to adjust the intake air volume of the direct exhaust pipeline 101 and the divided exhaust pipeline 102 to guide the exhaust gas of the engine 200 to the direct exhaust pipeline 101 and the divided exhaust pipeline 102 according to a set ratio; among them, the direct exhaust pipeline 101 and the divided exhaust pipeline 102 are respectively connected to the regulating valve 103; the divided exhaust pipeline 102 passes through the hydrogen storage package 300 to form a heat exchange therewith.
[0038] The hydrogen release rate of the hydrogen storage package is affected by the ambient temperature of its location. By adopting such a solution, the heat generated by the exhaust gas can be used to heat the hydrogen storage package 300, so as to release hydrogen therefrom. When it is necessary to reduce the hydrogen release, the exhaust gas entering the divided exhaust pipeline 102 is reduced, so as to slow down the hydrogen release rate inside the hydrogen storage package 300.
[0039] In some embodiments of the present application, the divided exhaust pipeline 102 is connected to the direct exhaust pipeline 101 after passing through the hydrogen storage package 300. That is, the divided exhaust pipeline 102 finally converges into the direct exhaust pipeline 101, which can save the externally arranged pipelines.
[0040] As a specific solution of the present application, the hydrogen pump 104 is used to pump out the hydrogen in the hydrogen storage package 300; among them, the hydrogen pump 104 is connected to the hydrogen storage package 300. The hydrogen storage cylinder 105 is used to store the hydrogen pumped out by the hydrogen pump 104; among them, the hydrogen storage cylinder 105 is connected to the hydrogen pump 104. The one-way valve 106 is used to make the air flow unidirectionally from the hydrogen pump 104 to the hydrogen storage cylinder 105; among them, the one-way valve 106 is connected between the hydrogen pump 104 and the hydrogen storage cylinder 105. The output pipeline 107 is used to guide the hydrogen stored in the hydrogen storage cylinder 105 to the engine 200; among them, the output pipeline 107 is connected to the hydrogen storage cylinder 105. The pressure gauge 108 is used to measure the pressure of the hydrogen storage cylinder 105; among them, the pressure gauge 108 is connected between the hydrogen storage cylinder 105 and the output pipeline 107.
[0041] Refer to Figure 1 As shown, that is, starting from the air outlet of the hydrogen storage package 300, the hydrogen pump 104, the one-way valve 106, the hydrogen storage cylinder 105, the pressure gauge 108, and the output pipeline 107 are connected in sequence, and finally the output pipeline 107 is connected to the intake port of the engine 200.
[0042] Due to the adoption of the solution of using the hydrogen storage cylinder 105 in cooperation with the hydrogen storage package 300 to achieve hydrogen supply, the hydrogen storage cylinder 105 can be used to store the hydrogen generated by the hydrogen storage package 300, and the hydrogen storage capacity per unit volume of the hydrogen storage package 300 is significantly higher than that of a high-pressure hydrogen storage tank. Compared with the conventional solution of using a high-pressure tank for hydrogen storage, the space occupied by the vehicle-mounted hydrogen storage system 100 can be significantly reduced, the load of vehicles and other equipment can be reduced, and it is convenient to be integrated on vehicles and other equipment.
[0043] As an alternative, the gas storage cylinder 105 is a high-pressure gas cylinder, and its main function is to provide hydrogen gas with sufficient pressure. Of course, in order to prevent excessive pressure, a pressure gauge 108 is required to monitor the internal air pressure thereof. The one-way valve 106 prevents hydrogen gas from flowing back into the hydrogen storage package 300.
[0044] As an alternative, the regulating valve 103 can at least adopt a three-way solenoid valve. Refer to Figure 5 As shown, the three-way solenoid valve has an air inlet 103a directly or indirectly connected to the gas storage cylinder 105, a first exhaust port 103b directly or indirectly connected to the direct exhaust pipeline 101, and a second exhaust port 103c directly or indirectly connected to the branched exhaust pipeline 102. And between the air inlet 103a and the first exhaust port 103b, and between the air inlet 103a and the second exhaust port 103c, there is a movable valve core. The valve core can be driven by an electric telescopic rod or the like to move relative to the valve body of the three-way solenoid valve, so as to control the opening and closing degree of the passages between the air inlet 103a and the first exhaust port 103b, and between the air inlet 103a and the second exhaust port 103c by using the movable valve core. The driving method of the above valve core is only an exemplary illustration, and the present application does not limit the driving method of the valve core.
[0045] The three-way solenoid valve can also be a combination of multiple electric valves. For example, one electric valve is directly or indirectly connected between the gas storage cylinder 105 and the direct exhaust pipeline 101, and another electric valve is directly or indirectly connected between the gas storage cylinder 105 and the branched exhaust pipeline 102, so as to control the gas flow rates in the direct exhaust pipeline 101 and the branched exhaust pipeline 102 by controlling the opening and closing degrees of the respective electric valves.
[0046] By adopting the above solution, the regulation of the tail gas distribution can be realized by adjusting the opening and closing degree of the branch. The most extreme case is to completely close one of the direct exhaust pipeline 101 or the branched exhaust pipeline 102.
[0047] As an alternative, the hydrogen storage package 300 is a metal hydrogen storage package, and its specific structure refers to Figure 3 or Figure 4 as shown.
[0048] The hydrogen storage package 300 includes: a housing 301, a first heat exchange structure, a second heat exchange structure, a medium valve 306, a hydrogen valve 305, and a mounting structure 308.
[0049] Among them, the housing 301 is used to form an inner space for storing the hydrogen storage material 302; the first heat exchange structure is used to heat the hydrogen storage material 302 in the inner space; the second heat exchange structure is used to cool the hydrogen storage material 302 in the inner space; at least part of the first heat exchange structure and the second heat exchange structure is arranged in the inner space and extends in a way that passes through the area where the hydrogen storage material 302 is stored.
[0050] As an alternative, the hydrogen storage material includes, but is not limited to, magnesium-based metal hydrogen storage materials, titanium-based hydrogen storage materials, rare earth metal hydrogen storage materials, and sodium borohydride.
[0051] Specifically, the first heat exchange structure includes: an exhaust gas pipeline 303; wherein, the exhaust gas pipeline 303 is used to provide a passage for the exhaust gas to pass through the inner space of the shell; the inner space of the exhaust gas pipeline 303 is isolated from the inner space of the shell. The exhaust gas pipeline 303 is a part of the above-mentioned split exhaust pipeline 102.
[0052] Specifically, the first heat exchange structure includes: a heating element 307; wherein, the heating element 307 is used to convert electrical energy into heat energy; the heating element 307 is arranged in the inner space of the shell.
[0053] Specifically, the second heat exchange structure includes: a medium pipeline 304; wherein, the medium pipeline 304 is used to provide a passage for the cooling medium to pass through the inner space of the shell; the inner space of the medium pipeline 304 is isolated from the inner space of the shell.
[0054] Both the heating element 307 and the medium pipeline 304 can expand their heat transfer ranges in the form of an "S" shape or the like. Of course, other methods can also be used to arrange the heating element 307 and the medium pipeline 304.
[0055] Specifically, the medium valve 306 is used to control the on or off of the medium pipeline 304. Separate medium valves 306 can be provided at the inlet and outlet of the medium pipeline, and the medium valve can adopt an electrically controlled valve.
[0056] Specifically, the hydrogen valve 305 is used to control the on or off between the inner space of the shell and the outside. Its control is related to the on or off of the hydrogen pump 104.
[0057] Specifically, the mounting structure 308 is used to detachably mount the hydrogen storage package 300 to the vehicle 1. It can adopt a quick-release structure such as a slide rail or a buckle.
[0058] Referring again to Figure 1 As shown, the hydrogen energy power system 10 of the present application further includes an engine 200, and the engine 200 can use hydrogen as fuel. The hydrogen output from the output pipeline 107 is supplied to the engine 200, and the exhaust gas of the engine 200 is connected to the regulating valve 103 and then distributed to the direct exhaust pipeline 101 and the split exhaust pipeline 102.
[0059] As an alternative, the regulating valve 103 is connected between the exhaust gas discharge pipeline of the engine, the direct exhaust pipeline 101, and the split exhaust pipeline 102, that is, the regulating valve 103 controls the on or off and the flow rate of the engine exhaust gas flowing to the direct exhaust pipeline 101 and the split exhaust pipeline 102.
[0060] Referring to Figure 6As shown in the figure, the present application also provides a vehicle 1, which at least includes the above-mentioned hydrogen energy power system 10.
[0061] Referring to Figures 1 to 2 As shown in the figure, the control process and operation process of the present application are described in detail as follows:
[0062] Hydrogen is provided by the hydrogen storage package 300 and is pressurized by the hydrogen pump 104 and then input into the gas storage cylinder 105. A one-way valve 106 is used in the middle to prevent hydrogen from flowing back. The overall pressure of hydrogen in the gas storage cylinder 105 should be dynamically maintained within a certain range. For example, a pressure gauge 108 can be used to detect the air pressure in the gas storage cylinder 105, and the detected data is sent to the vehicle-mounted controller (Electronic Control Unit, hereinafter referred to as "ECU") in the form of an electrical signal. After receiving the electrical signal, the ECU determines whether the air pressure in the gas storage cylinder 105 is within a reasonable range. Generally, it should be between 5 and 20 MPa to ensure that the hydrogen storage capacity meets the requirements of cold start and there is enough pressure to inject into the cylinder block of the engine 200. Finally, the gas storage cylinder 105 is directly connected to the hydrogen injector to provide fuel for the engine 200.
[0063] If the air pressure in the gas storage cylinder 105 exceeds or is lower than the reasonable range, the ECU can control and adjust the valve 103 to adjust the gas flow rate in the branch pipeline 102, etc., to control the hydrogen release rate in the hydrogen storage package 300, and finally realize the control of the air pressure in the gas storage cylinder 105. Of course, the above solution should be understood as an exemplary description of the air pressure control method in the gas storage cylinder 105, rather than a limitation on the specific control solution of the air pressure in the gas storage cylinder 105.
[0064] The main control objects of the vehicle-mounted hydrogen storage system 100 provided by the present application are the opening and closing degree of the regulating valve 103, the temperature of the hydrogen storage package 300, and the pressure of the gas storage cylinder 105. When the pressure in the gas storage cylinder 105 is lower than the design pressure, the regulating valve 103 should increase the tail gas flow rate to the hydrogen storage package 300 to heat the hydrogen storage package 300, so as to increase the hydrogen supply and ensure the stability of the pressure in the gas storage cylinder 105. When the pressure in the gas storage cylinder 105 is too high, the regulating valve 103 should reduce the tail gas flow rate to the hydrogen storage package 300 to reduce the hydrogen supply. Since the temperature control delay of the hydrogen storage package 300 is relatively large and the hydrogen demand fluctuation of the engine 200 is also very large. By limiting the upper and lower limits of the pressure of the gas that can be stored in the gas storage cylinder 105 to meet the use requirements, a pressure gauge 108 is set to monitor the pressure of the gas in the gas storage cylinder 105, and a control model is established in the ECU to detect the air pressure in the gas storage cylinder 105 and control and adjust the regulating valve 103 in advance to change the flow rate of the tail gas flowing to the hydrogen storage package 300.
[0065] The hydrogen storage package 300 adopted in this application does not limit the selected metal hydrogen storage material 302, but the hydrogen release temperature should be such that after the hydrogen enters the engine to participate in the reaction to generate exhaust gas, the temperature of the engine exhaust gas is within a controllable temperature range (for example, not exceeding 500 °C).
[0066] The hydrogen pump 104 adopted in this application should be able to pressurize hydrogen to above 5 MPa, and specifically, for example, it can be achieved by selecting the type of the hydrogen pump 104.
[0067] The gas storage cylinder 105 adopted in the technical solution of this application should be able to withstand high-pressure hydrogen of 20 MPa and have a certain volume to ensure the need for cold start of the engine 200. The volume of the gas storage cylinder 105 can be selected according to actual needs, and this application does not make any restrictions.
[0068] The pressure gauge 108 adopted in the technical solution of this application should be able to measure the pressure of the gas storage cylinder 105 and transmit it to the vehicle ECU, and the pressure gauge 108 should be able to accurately measure the hydrogen pressure not lower than 20 MPa.
[0069] The entire hydrogen pipeline and corresponding components adopted in the technical solution of this application should all be strictly sealed and withstand the corresponding hydrogen pressure, and the specific sealing form is not restricted here.
[0070] The regulating valve 103 adopted in the technical solution of this application can adjust the amount of exhaust gas leading to the hydrogen storage package 300 in an electric control manner, and further adjust the hydrogen generation rate of the hydrogen storage package 300 by affecting the temperature inside the hydrogen storage package. Specifically, the regulating valve 103 can be electrically connected to the ECU so that the ECU can control the opening and closing degree of the regulating valve 103. Of course, other electric control methods can also be used to control the opening and closing of the regulating valve 103, and this application does not make any restrictions on this.
[0071] The ECU can also be configured to be able to calculate and look up parameters such as the fuel consumption of the engine 200, the temperature of the hydrogen storage package 300, the pressure of the gas in the gas storage cylinder 105, and the opening of the regulating valve 103. Specifically, corresponding types of sensors can be set on the engine 200, the hydrogen storage package 300, and the gas storage cylinder 105. These sensors send electrical signals containing information such as the corresponding fuel consumption, temperature value, and air pressure value to the ECU, and the regulating valve 103 is controlled through the program built in the ECU to comprehensively control the hydrogen supply amount.

[0074] Among the embodiments, implementation manners and related technical features of the present application, they can be combined and replaced with each other without conflict.
