[0021] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0023] Figure 1 The structure diagram of a vehicle-mounted hydrogen storage system is shown. 11. Hydrogen storage bottle; 12. Bottle valve; 13. High-pressure pressure sensor; 14. Hydrogen filling port; 15. Hydrogen concentration detection sensor; 16. Pressure reducing valve; 17. Medium-pressure pressure sensor; 18. Fuel cell FC; 19. Vehicle controller; 20. Hydrogen storage controller (HMS, hydrogen management system); The specific principle will not be repeated here.

[0024] To ensure the safety of the hydrogen storage system, the high-pressure pressure sensor will issue an alarm when it detects abnormal pressure. In actual application, during operations such as loading and unloading, debugging, and hydrogen replacement, the high-pressure pressure sensor will detect that the pressure is too low, and the hydrogen storage controller 20 will control and issue an invalid fault alarm. In order to avoid the failure of the hydrogen storage system to debug and cause the whole vehicle to be unable to be high-voltage, it is necessary to cut off the low-voltage wiring harness connector. However, the connector of the hydrogen storage controller 20 is arranged under the cab or inside the hydrogen storage system, and the plugging and unplugging operation is extremely inconvenient, labor-consuming and time-consuming. At the same time, multiple plugging and unplugging of the low-voltage wiring harness connector will cause deformation and ablation of the pins, resulting in poor contact of the line and increasing the quality risk of the whole vehicle.

[0025] Based on the above, see Figure 2 , which shows a flow chart of the implementation of the control method of the vehicle-mounted hydrogen storage system provided by an embodiment of the present invention, which is applied to a hydrogen fuel cell vehicle, which is equipped with a hydrogen storage system. Figure 1 The execution body of the control method of the vehicle-mounted hydrogen storage system may be the hydrogen storage controller 20, or may be other controllers of the vehicle that can control the hydrogen storage system, and no specific limitation is made here.

[0026] The above method is described in detail as follows:

[0027] S101: Acquire the activation status of the hydrogen storage system;

[0028] S102: If the activation state of the hydrogen storage system is inactive, detecting the pressure value of the hydrogen storage system, and updating the activation state of the hydrogen storage system according to the pressure value of the hydrogen storage system;

[0029] S103: If the activation state of the hydrogen storage system is activated, the actual operating parameters of the hydrogen storage system are obtained, and an alarm is issued according to the actual operating parameters of the hydrogen storage system.

[0030] In the embodiment of the present invention, the activation state of the hydrogen storage system is set, and only when the activation state of the hydrogen storage system is activated, an alarm is issued according to the actual operating parameters. Before the vehicle is offline for testing and debugging or before hydrogen replacement, the activation state of the hydrogen storage system can be set to inactivated. Even if the hydrogen storage tank is not inflated, the fault alarm will not be triggered, which can effectively avoid invalid fault alarms during the debugging process, improve the information processing efficiency of the whole vehicle, greatly reduce the difficulty of operation, and improve the work efficiency. At the same time, there is no need to manually cut off the low-voltage line of the hydrogen storage controller 20, which will not damage the connector and reduce the quality risk of the whole vehicle.

[0031] Exemplarily, the activation status of the hydrogen storage system can be written by software. For example, writing "not activated" before the vehicle is offline for debugging; or writing "not activated" before the hydrogen replacement operation. The situations where the "not activated" status is written include but are not limited to the above two. According to actual application requirements, the "not activated" status can be written when the hydrogen storage system alarm is not required to avoid invalid fault alarms in the hydrogen storage system.

[0032] It should be noted that the pressure value of the hydrogen storage system can be obtained by Figure 1 It is detected by the high pressure sensor in.

[0033] In a possible implementation manner, steps S101 to S103 are repeatedly performed.

[0034] The status of the hydrogen storage system needs to be monitored in real time during vehicle use. Therefore, S101 to S103 is a repetitive process, and real-time monitoring continuously updates the activation status of the hydrogen storage system so as to timely understand the status of the hydrogen storage system and issue an alarm.

[0035] In a possible implementation, before S102, the method may further include:

[0036] S104: Detecting the pressure value of the hydrogen storage system;

[0037] S105: If the pressure value of the hydrogen storage system is greater than a preset pressure value, the pressure value is stored in a preset storage area.

[0038] In the embodiment of the present invention, the pressure value of the hydrogen storage system is recorded to update the activation state of the hydrogen storage system.

[0039] Specifically, a pressure value not greater than a preset pressure value may also be stored in a preset storage area at the same time to obtain complete pressure data of the hydrogen storage system.

[0040] In a possible implementation, S102 may include:

[0041] S1021: If the pressure value of the hydrogen storage system is not less than the preset pressure value, updating the activation state of the hydrogen storage system to activated;

[0042] S1022: If the pressure value of the hydrogen storage system is less than the preset pressure value, the activation state of the hydrogen storage system is updated according to the pressure value stored in the preset storage area.

[0043] When it is detected that the pressure value of the hydrogen storage system reaches the preset pressure value, it means that the hydrogen storage tank has been debugged and filled, or the hydrogen storage tank has been replaced, and the alarm can be normally activated at this time, then the activation state of the hydrogen storage system is updated to activated, and the alarm is activated. If the pressure value of the hydrogen storage system does not reach the preset pressure value, it may be that the hydrogen storage tank has not been filled or has been filled but the pressure is insufficient, then it can be determined whether to activate the alarm based on the previously stored pressure value.

[0044] In a possible implementation, updating the activation state of the hydrogen storage system according to the pressure value stored in the preset storage area may include:

[0045] 1. If there is data greater than the preset pressure value in the preset storage area, the activation state of the hydrogen storage system is updated to activated;

[0046] 2. If there is no data greater than the preset pressure value in the preset storage area, the activation status of the hydrogen storage system will not be updated.

[0047] If the activation status of the hydrogen storage system is not written correctly, or the activation status is lost after the device is replaced, it is detected that the pressure value of the hydrogen storage system is less than the preset pressure value. It may be that the hydrogen storage tank is not inflated, or it has been inflated but the pressure is low, and the state of the hydrogen storage system cannot be accurately determined. Since the pressure value of the hydrogen storage system is stored in S104 to S105, it is possible to determine whether the hydrogen storage tank has been inflated based on the data stored in the preset storage area. When the pressure value of the hydrogen storage system is less than the preset pressure value, but there is data greater than the preset pressure value in the preset storage area, it means that the hydrogen storage tank has been inflated and the alarm should be activated. When the pressure value of the hydrogen storage system is not less than the preset pressure value, and there is data greater than the preset pressure value in the preset storage area, it means that the hydrogen storage tank is not inflated and the alarm should not be activated. The above can accurately judge the state of the hydrogen storage system and accurately activate the alarm.

[0048] In a possible implementation manner, the preset pressure value may be 10 MPa.

[0049] The preset pressure value can be set according to actual application requirements and is not limited here.

[0050] In a possible implementation, the above method may further include:

[0051] S106: Sending the activation status of the hydrogen storage system to the vehicle controller;

[0052] S107: The vehicle controller is used to control the display screen of the vehicle to display the hydrogen storage system alarm "not activated" when the activation state of the hydrogen storage system is "not activated"; and to control the display screen of the vehicle to not display the hydrogen storage system alarm when the activation state of the hydrogen storage system is "activated".

[0053] In the embodiment of the present invention, the activation status can be sent to the vehicle controller. When the activation status is inactivated, the vehicle controller controls the vehicle display screen to display that the hydrogen storage system is inactivated, for example, displaying words such as "hydrogen storage system inactivated" or "hydrogen storage alarm inactivated", so that users or debugging personnel can intuitively understand the activation status of the current hydrogen storage system, and facilitate debugging and other operations. When the activation status is activated, the activation status is not displayed on the vehicle display screen.

[0054] Specifically, when the activation state is activated, it may be displayed on the vehicle display screen that the hydrogen storage system is activated.

[0055] In a possible implementation, the actual operating parameters of the hydrogen storage system may include: a pressure value of the hydrogen storage system, a temperature value of the hydrogen storage system, and a hydrogen concentration of the hydrogen storage system;

[0056] S103 may include:

[0057] S1031: Issue an alarm based on the pressure value, temperature value and hydrogen concentration of the hydrogen storage system.

[0058] When the activation state is activated, a normal alarm is started. For example, an alarm is issued when the temperature value of the hydrogen storage system is too high or too low, an alarm is issued when the hydrogen concentration of the hydrogen storage system is too high, or an alarm is issued when the pressure value of the hydrogen storage system is too high or too low.

[0059] It should be noted that the actual operating parameters of the hydrogen storage system include but are not limited to the above, and an alarm can be issued according to the actual operating parameters based on actual application requirements.

[0060] In a possible implementation, the above method may further include:

[0061] When it is detected that the vehicle is powered on, the hydrogen storage system performs a self-check; steps S101 to S103 are executed only if the self-check is normal, otherwise the whole vehicle alarm is activated.

[0062] Specifically, the self-test of the hydrogen storage system includes, but is not limited to, self-test of the opening state of the solenoid valve, self-test of the hydrogen concentration, self-test of the temperature, and self-test of the pressure.

[0063] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0069] The second judgment module 33 is used to obtain actual operating parameters of the hydrogen storage system if the activation state of the hydrogen storage system is activated, and issue an alarm according to the actual operating parameters of the hydrogen storage system.

[0070] In a possible implementation manner, the above device may further include:

[0071] Pressure monitoring module, used to detect the pressure value of the hydrogen storage system;

[0072] The pressure storage module is used to store the pressure value in a preset storage area if the pressure value of the hydrogen storage system is greater than a preset pressure value.

[0076] In a possible implementation, the activation status updating unit may be specifically used for:

[0077] 1. If there is data greater than the preset pressure value in the preset storage area, the activation state of the hydrogen storage system is updated to activated;

[0078] 2. If there is no data greater than the preset pressure value in the preset storage area, the activation status of the hydrogen storage system will not be updated.
