Description

Technical Field

[0001] This invention relates to the field of fuel cell vehicles, and more particularly to a hydrogen SOC management method for fuel cell vehicles, a computer-readable storage medium, a hydrogen SOC management device for fuel cell vehicles, and a fuel cell vehicle. Background Technology

[0002] Currently, fuel cell vehicles are recognized worldwide as zero-emission and environmentally friendly vehicles. The on-board hydrogen storage system is similar to the fuel tank of a traditional car, including components such as hydrogen storage cylinders, cylinder valves, pressure reducing valves, and hydrogen system controllers, and undertakes functions such as hydrogen storage (including hydrogen SOC management), refueling, and supply.

[0003] However, the problem with this technology is that, during the shutdown process of a fuel cell vehicle, due to the design of the vehicle's software strategy, the hydrogen storage system may have closed the cylinder valve, but the fuel cell system may still be using hydrogen. This means that the hydrogen in the internal pipelines of the hydrogen storage system continues to be consumed, resulting in the actual pressure in the high-pressure pipelines being lower than the hydrogen cylinder pressure. Consequently, when the fuel cell vehicle is restarted, the hydrogen SOC display will show a jump, making it difficult for users to understand the actual hydrogen storage capacity of the hydrogen storage system and causing confusion for users managing their fuel cell vehicles. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to propose a hydrogen SOC management method for fuel cell vehicles. This method can acquire the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and control the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode. This ensures that the hydrogen SOC does not experience a significant jump upon the next start-up of the fuel cell vehicle, facilitating user management of the fuel cell vehicle's hydrogen reserves without altering the original structure of the fuel cell vehicle, effectively avoiding increased vehicle manufacturing costs.

[0005] A second objective of this invention is to provide a computer-readable storage medium.

[0006] The third objective of this invention is to provide a hydrogen SOC management device for fuel cell vehicles.

[0007] The fourth objective of this invention is to provide a fuel cell vehicle.

[0008] To achieve the above objectives, a first aspect of the present invention provides a hydrogen SOC management method for a fuel cell vehicle, wherein the fuel cell vehicle includes a hydrogen storage system, and the method includes the following steps: acquiring the high-pressure of the hydrogen storage system and the average temperature of the hydrogen storage cylinders in the hydrogen storage system, and acquiring the real-time hydrogen SOC of the hydrogen storage system based on the high-pressure and the average temperature; when the fuel cell vehicle exits the electric combustion mode, acquiring the current hydrogen SOC of the hydrogen storage system and closing the cylinder valves of each hydrogen storage cylinder; controlling the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode.

[0009] According to the hydrogen SOC management method for fuel cell vehicles implemented in this invention, the high-pressure of the hydrogen storage system and the average temperature of each hydrogen storage cylinder in the system are obtained. The real-time hydrogen SOC of the hydrogen storage system is obtained based on the high-pressure and average temperature. Then, when the fuel cell vehicle exits the electric combustion mode, the current hydrogen SOC of the hydrogen storage system is obtained, and the valves of each hydrogen storage cylinder are closed. Furthermore, the on-board equipment is controlled to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. Therefore, by obtaining the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and controlling the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode, the hydrogen SOC will not experience a significant jump upon the next start-up of the fuel cell vehicle. This facilitates user management of the hydrogen storage capacity of the fuel cell vehicle without altering its original structure, effectively avoiding increased vehicle manufacturing costs.

[0010] In addition, the hydrogen SOC management method for fuel cell vehicles according to the above embodiments of the present invention may further include the following additional technical features:

The method further includes: obtaining the high-pressure of the hydrogen storage system through the high-pressure sensor, and obtaining the average temperature of each hydrogen storage cylinder in the hydrogen storage system through the temperature sensor.

[0012] According to one embodiment of the present invention, before obtaining the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and the average temperature, the method further includes: controlling the valve of each hydrogen storage cylinder to open and close at least once; and obtaining the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and the average temperature.

[0013] According to one embodiment of the present invention, obtaining the current hydrogen SOC of the hydrogen storage system includes: obtaining the real-time hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode; and determining the real-time hydrogen SOC of the hydrogen storage system as the current hydrogen SOC of the hydrogen storage system.

[0014] According to one embodiment of the present invention, after the fuel cell vehicle re-enters the electric combustion mode, the method further includes: controlling the valve of each hydrogen storage cylinder to open and close at least once; obtaining the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and the average temperature; and controlling the on-board equipment to display the real-time hydrogen SOC of the hydrogen storage system.

[0015] According to one embodiment of the present invention, the on-board device obtains the real-time hydrogen SOC and the current hydrogen SOC of the hydrogen storage system through the vehicle CAN bus.

[0016] According to one embodiment of the present invention, the vehicle-mounted device includes a vehicle-mounted instrument panel and a vehicle-mounted terminal.

[0017] To achieve the above objectives, a computer-readable storage medium is provided in a second aspect embodiment of the present invention, on which a hydrogen SOC management program for a fuel cell vehicle is stored, wherein the hydrogen SOC management program for the fuel cell vehicle is executed by a processor to implement the above-described hydrogen SOC management method for a fuel cell vehicle.

[0018] According to embodiments of the present invention, a computer-readable storage medium, through a processor executing a hydrogen SOC management program for a fuel cell vehicle stored thereon, can obtain the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode, and control the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode. This ensures that the hydrogen SOC does not experience a significant jump when the fuel cell vehicle starts up again, facilitating user management of the hydrogen storage capacity of the fuel cell vehicle without altering its original structure, effectively avoiding increased vehicle manufacturing costs.

[0019] To achieve the above objectives, a third aspect of the present invention provides a hydrogen SOC management device for a fuel cell vehicle, the fuel cell vehicle including a hydrogen storage system, the device comprising: an acquisition module for acquiring the high pressure of the hydrogen storage system and the average temperature of the hydrogen storage cylinders in the hydrogen storage system, and acquiring the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and the average temperature; a control module for acquiring the current hydrogen SOC of the hydrogen storage system and closing the cylinder valves of each hydrogen storage cylinder when the fuel cell vehicle exits the electric combustion mode; and a display module for controlling the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode.

[0020] According to an embodiment of the present invention, the hydrogen SOC management device for a fuel cell vehicle acquires the high-pressure of the hydrogen storage system and the average temperature of each hydrogen storage cylinder in the system via an acquisition module. Based on the high-pressure and average temperature, it acquires the real-time hydrogen SOC of the hydrogen storage system. Then, when the fuel cell vehicle exits the electric combustion mode, the control module acquires the current hydrogen SOC of the hydrogen storage system and closes the valves of each hydrogen storage cylinder. The display module controls the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. Therefore, by acquiring the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and controlling the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode, the hydrogen SOC will not experience a significant jump upon the next start-up of the fuel cell vehicle. This facilitates user management of the hydrogen storage capacity of the fuel cell vehicle without altering its original structure, effectively avoiding increased vehicle manufacturing costs.

[0021] To achieve the above objectives, the fourth aspect of the present invention provides a fuel cell vehicle including a hydrogen SOC management device for the fuel cell vehicle.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following description, with reference to the accompanying drawings, describes a hydrogen SOC management method, a computer storage medium, a hydrogen SOC management device, and a fuel cell vehicle according to embodiments of the present invention.

[0032] Before introducing the hydrogen SOC management method and device for fuel cell vehicles according to embodiments of the present invention, the specific structure of the fuel cell vehicle according to embodiments of the present invention will be described accordingly.

[0033] Specifically, such as Figure 1 As shown, the fuel cell vehicle 1000 includes a hydrogen storage system 100 and a fuel cell system 200. The hydrogen storage system 100 typically consists of several gas cylinders / cylinder valves connected in parallel, and can supply hydrogen to the fuel cell system 200 by adjusting the pipeline pressure through a pressure reducing valve.

[0034] Figure 2 This is a schematic flowchart of a hydrogen SOC management method for a fuel cell vehicle according to an embodiment of the present invention.

[0035] like Figure 2As shown, the hydrogen SOC management method for fuel cell vehicles includes the following steps:

[0036] S101, obtain the high pressure of the hydrogen storage system and the average temperature of the hydrogen storage cylinder in the hydrogen storage system, and obtain the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and average temperature.

[0037] Specifically, in some embodiments of the present invention, the high pressure P of the hydrogen storage system and the average temperature T of each hydrogen storage cylinder in the hydrogen storage system can be obtained in real time. 平均 In order to facilitate the calculation based on the high pressure P and the average temperature T 平均 Obtain the real-time state of charge (SOC) of hydrogen in the hydrogen storage system.

[0038] Alternatively, the real-time state of hydrogen (SOC) of the hydrogen storage system can be obtained using the following formula:

[0039] Hydrogen SOC = ρ(P, T) 平均 ) / ρ (nominal pressure, standard temperature);

[0040] It should be noted that the nominal pressure can be set according to the hydrogen storage requirements and vehicle space. For example, the nominal pressure can be 35 MPa or 70 MPa. The standard temperature can be set accordingly to the nominal pressure of 35 MPa or 70 MPa. For example, the standard temperature can be 15℃.

[0041] Where P is the high pressure of the hydrogen storage system, and T is the high pressure of the hydrogen storage system. 平均 T represents the average temperature of the hydrogen storage cylinder. 平均 = (T1+T2+…+Tn) / n, where Tn is the temperature of the nth hydrogen storage cylinder and n is the number of hydrogen storage cylinders.

[0042] S102: When the fuel cell vehicle exits the electric combustion mode, it obtains the current hydrogen SOC of the hydrogen storage system and closes the valve of each hydrogen storage cylinder.

[0043] Specifically, in some embodiments of the present invention, when a fuel cell vehicle exits the electric combustion mode, the hydrogen storage system controller can close the cylinder valve set for each hydrogen storage cylinder according to the electric combustion command, and obtain the current hydrogen SOC of the hydrogen storage system before controlling the cylinder valve to close, and latch it.

[0044] S103 controls the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode.

[0045] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can also control the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. The current hydrogen SOC is the current hydrogen SOC of the hydrogen storage system acquired and locked by the hydrogen storage system controller before the control cylinder valve is closed.

[0046] It should be understood that, in the above embodiments of the present invention, the hydrogen storage system controller can obtain the high-pressure of the hydrogen storage system and the average temperature of the hydrogen storage cylinders in the hydrogen storage system, and obtain the real-time hydrogen SOC of the hydrogen storage system based on the high-pressure and average temperature. Therefore, when the fuel cell vehicle exits the electric combustion mode, the controller can obtain the current hydrogen SOC of the hydrogen storage system, close the valves of each hydrogen storage cylinder, and control the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. Thus, by obtaining the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and controlling the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode, the hydrogen SOC will not show a significant jump when the fuel cell vehicle starts again, facilitating user management of the hydrogen storage capacity of the fuel cell vehicle without altering its original structure, effectively avoiding increased vehicle manufacturing costs.

[0047] Furthermore, the fuel cell vehicle includes a high-pressure sensor disposed between the hydrogen storage system and the fuel cell system, and a temperature sensor disposed on the valve of each hydrogen storage cylinder. The method further includes: obtaining the high-pressure of the hydrogen storage system through the high-pressure sensor, and obtaining the average temperature of each hydrogen storage cylinder in the hydrogen storage system through the temperature sensor.

[0048] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can obtain the high-pressure P of the hydrogen storage system through a high-pressure sensor installed between the hydrogen storage system and the fuel cell system, and can obtain the average temperature T of the hydrogen storage cylinder through a temperature sensor installed on the cylinder valve of each hydrogen storage cylinder. 平均 .

[0049] Furthermore, before obtaining the real-time hydrogen SOC of the hydrogen storage system based on high pressure and average temperature, such as Figure 3 As shown, the method also includes:

[0050] S201, control the opening and closing of the valve of each hydrogen storage cylinder at least once.

[0051] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can control the valve of each hydrogen storage cylinder to open and close at least once, thereby restoring the high pressure of the hydrogen storage system to be consistent with the pressure inside the hydrogen storage cylinder.

[0052] S202, obtains the real-time hydrogen SOC of the hydrogen storage system based on high pressure and average temperature.

[0053] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can obtain the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and average temperature after controlling the opening and closing of the valve of each hydrogen storage cylinder at least once, thereby ensuring the accuracy of the hydrogen SOC.

[0054] It should be understood that, in the above embodiments of the present invention, the hydrogen storage system controller can control the valve of each hydrogen storage cylinder to open and close at least once, and then, based on the restored high pressure P and average temperature T... 平均 By obtaining the real-time hydrogen SOC of the hydrogen storage system, the hydrogen SOC of the fuel cell vehicle will not fluctuate significantly when it is started again, so that users can manage the hydrogen storage of the fuel cell vehicle.

[0055] Furthermore, obtaining the current hydrogen SOC of the hydrogen storage system includes: obtaining the real-time hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode, and determining the real-time hydrogen SOC of the hydrogen storage system as the current hydrogen SOC of the hydrogen storage system.

[0056] Specifically, in some embodiments of the present invention, when a fuel cell vehicle exits the electric combustion mode, the fuel cell vehicle can send an electric combustion command to the entire vehicle via the CAN bus. At this time, the hydrogen storage system controller can close the cylinder valve according to the electric combustion command, and before the cylinder valve is closed, record and latch the real-time hydrogen SOC, and then determine the latched real-time hydrogen SOC of the hydrogen storage system as the current hydrogen SOC of the hydrogen storage system, and output it in real time.

[0057] Furthermore, after the fuel cell vehicle re-enters electric mode, such as Figure 4 As shown, the method also includes:

[0058] S301, control the opening and closing of the valve of each hydrogen storage cylinder at least once;

[0059] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can control the valve of each hydrogen storage cylinder to open and close at least once, thereby restoring the high pressure of the hydrogen storage system to be consistent with the pressure inside the hydrogen storage cylinder.

[0060] S302, obtains the real-time hydrogen SOC of the hydrogen storage system based on high pressure and average temperature;

[0061] Specifically, in some embodiments of the present invention, the hydrogen storage system controller can obtain the real-time hydrogen SOC of the hydrogen storage system based on the high pressure and average temperature after controlling the opening and closing of the valve of each hydrogen storage cylinder at least once, thereby ensuring the accuracy of the hydrogen SOC.

[0062] S303 controls the onboard equipment to display the real-time hydrogen SOC of the hydrogen storage system.

[0063] Specifically, in some embodiments of the present invention, after the fuel cell vehicle re-enters the electric combustion mode, and the hydrogen storage system controller obtains the real-time hydrogen SOC of the hydrogen storage system based on the high pressure after controlling the opening and closing of the hydrogen storage cylinder valve at least once and the average temperature of the hydrogen storage cylinder, the hydrogen storage system can also send the real-time hydrogen SOC to the vehicle CAN bus so as to control the on-board equipment to display the real-time hydrogen SOC of the hydrogen storage system.

[0064] It should be understood that, in the above embodiments of the present invention, after the fuel cell vehicle re-enters the electric combustion mode, the hydrogen storage system controller can control the valve of each hydrogen storage cylinder to open and close at least once, and then adjust the pressure P and average temperature T after correction and recovery. 平均 The system acquires the real-time hydrogen SOC of the hydrogen storage system and controls the on-board equipment to display the real-time hydrogen SOC of the hydrogen storage system. This corrects the hydrogen SOC after the fuel cell vehicle re-enters the electric mode, ensuring that the hydrogen level does not fluctuate significantly when the fuel cell vehicle starts up again. It also accurately displays the real-time hydrogen SOC of the hydrogen storage system, making it easier for users to manage the hydrogen storage capacity of the fuel cell vehicle.

[0065] Furthermore, the on-board equipment obtains the real-time hydrogen SOC and the current hydrogen SOC of the hydrogen storage system through the vehicle's CAN bus.

[0066] Specifically, in some embodiments of the present invention, after the hydrogen storage system controller obtains the real-time hydrogen SOC and the current hydrogen SOC of the hydrogen storage system, it can also send the real-time hydrogen SOC and the current hydrogen SOC of the hydrogen storage system to the vehicle CAN bus. Then, the on-board equipment can obtain the real-time hydrogen SOC and the current hydrogen SOC of the hydrogen storage system through the vehicle CAN bus and display them.

[0067] Furthermore, in-vehicle equipment includes in-vehicle instruments and in-vehicle terminals.

[0068] Specifically, in some embodiments of the present invention, the real-time hydrogen SOC and the current SOC of the hydrogen storage system can be displayed through vehicle instruments and vehicle terminals, thereby making it easier for users to intuitively understand the hydrogen storage capacity of the hydrogen storage system.

[0069] The following is in conjunction with the appendix Figure 5 The specific process steps of the hydrogen SOC management method for fuel cell vehicles are described below with reference to specific embodiments of the present invention, such as... Figure 5 As shown, after the fuel cell vehicle is started, the following steps are performed:

[0070] S1 controls the valve of each hydrogen storage cylinder to open and close at least once, based on the high pressure P and average temperature T. 平均 The real-time state of hydrogen (SOC) of the hydrogen storage system is obtained to control the on-board equipment to display the real-time SOC of the hydrogen storage system.

[0071] S2, when the fuel cell vehicle exits the fuel cell electric mode, the hydrogen storage system controller closes the cylinder valve according to the fuel cell electric command, and before the cylinder valve closes, it records and latches the current hydrogen SOC before the cylinder valve closes, and controls the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system.

[0072] S3, the fuel cell vehicle re-enters the electric power mode and returns to step S1.

[0073] In summary, the hydrogen SOC management method for fuel cell vehicles according to the present invention obtains the high-pressure of the hydrogen storage system and the average temperature of each hydrogen storage cylinder in the system, and obtains the real-time hydrogen SOC of the hydrogen storage system based on the high-pressure and average temperature. Then, when the fuel cell vehicle exits the electric combustion mode, the current hydrogen SOC of the hydrogen storage system is obtained, the cylinder valves of each hydrogen storage cylinder are closed, and the on-board equipment is controlled to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. Therefore, by obtaining the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and controlling the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode, the hydrogen SOC of the fuel cell vehicle will not experience a significant jump upon the next start-up, facilitating user management of the fuel cell vehicle's hydrogen storage capacity without altering the original structure of the fuel cell vehicle, effectively avoiding increased vehicle manufacturing costs.

[0074] Based on the hydrogen SOC management method for fuel cell vehicles described in the foregoing embodiments of the present invention, the present invention also proposes a computer-readable storage medium storing a corresponding hydrogen SOC management program for fuel cell vehicles. When the processor executes the hydrogen SOC management program for fuel cell vehicles, the hydrogen SOC management method for fuel cell vehicles described in the foregoing embodiments of the present invention can be implemented.

[0075] It should be noted that other specific embodiments of the computer-readable storage medium of the present invention can be found in the specific embodiments of the hydrogen SOC management method for fuel cell vehicles described above. To reduce redundancy, they will not be repeated here.

[0076] In summary, the computer-readable storage medium according to embodiments of the present invention, which stores a hydrogen SOC management program for a fuel cell vehicle thereon, eliminates potential fluctuations in instrument hydrogen SOC during fuel cell vehicle startup by latching the hydrogen SOC when the fuel cell vehicle is stopped and correcting the hydrogen SOC when the fuel cell vehicle is started, without changing the hardware structure. This improves the stability of fuel cell vehicle startup and enhances the user's driving experience.

[0080] The control module 20 is used to obtain the current hydrogen SOC of the hydrogen storage system and close the cylinder valve of each hydrogen storage cylinder when the fuel cell vehicle exits the electric combustion mode.

[0081] The display module 30 is used to control the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode.

[0082] It should be noted that other specific embodiments of the hydrogen SOC management device for fuel cell vehicles in this embodiment of the invention can be found in the specific embodiments of the hydrogen SOC management method for fuel cell vehicles described above. To reduce redundancy, they will not be repeated here.

[0083] In summary, the hydrogen SOC management device for a fuel cell vehicle according to embodiments of the present invention acquires the high-pressure of the hydrogen storage system and the average temperature of each hydrogen storage cylinder in the hydrogen storage system through an acquisition module, and obtains the real-time hydrogen SOC of the hydrogen storage system based on the high-pressure and average temperature. Then, when the fuel cell vehicle exits the electric combustion mode, the control module acquires the current hydrogen SOC of the hydrogen storage system, closes the cylinder valves of each hydrogen storage cylinder, and controls the on-board equipment to continuously display the current hydrogen SOC of the hydrogen storage system until the fuel cell vehicle re-enters the electric combustion mode. Therefore, by acquiring the current hydrogen SOC of the hydrogen storage system when the fuel cell vehicle exits the electric combustion mode and controlling the on-board equipment to continuously display the current hydrogen SOC until the fuel cell vehicle re-enters the electric combustion mode, the hydrogen SOC of the fuel cell vehicle will not experience a significant jump upon the next start-up, facilitating user management of the hydrogen storage capacity of the fuel cell vehicle without altering its original structure, effectively avoiding increased vehicle manufacturing costs.
