After the replacement and refueling process is complete, the fault shielding is removed to restore the control system to normal. However, this fault shielding operation can affect some faults that would otherwise be detected during the replacement and refueling process, impacting hydrogen refueling reliability. Summary of the Invention

[0006] If it is detected that the high pressure of the hydrogen storage system is lower than the first preset pressure threshold and higher than the second preset pressure threshold, and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, then the fault type of the hydrogen storage system is the first fault;

[0007] If it is detected that the high pressure of the hydrogen storage system is lower than the second preset pressure threshold and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, the fault type of the hydrogen storage system is the second fault;

[0008] If the fault type is the first fault, directly alarm the first fault;

[0009] If the fault type is the second fault, no alarm is given when the hydrogenation replacement process of the hydrogen storage system is not completed; when the hydrogenation replacement process of the hydrogen storage system is completed, an alarm is given for the second fault.

[0010] In combination with the first aspect, an embodiment of the present invention provides a first possible implementation of the first aspect, wherein the method further includes:

[0011] If the preset condition is triggered, the counter will be counted;

[0012] When the count value of the counter is greater than a preset count threshold, the hydrogenation replacement process of the hydrogen storage system is completed.

[0013] In combination with the first aspect, an embodiment of the present invention provides a second possible implementation of the first aspect, wherein if a preset condition is triggered, the step of performing a counting operation on the counter includes:

[0014] If the high pressure of the hydrogen storage system increases in response to the hydrogen refueling request and the high pressure does not exceed the first preset pressure threshold, a preset condition is triggered and the count value of the counter is controlled to increase by one.

[0015] In combination with the first aspect, an embodiment of the present invention provides a third possible implementation scheme of the first aspect, wherein the high pressure is the gas pressure in the gas cylinder in the hydrogen storage system, and the medium pressure is the gas pressure in the outlet pipeline of the pressure reducing valve in the hydrogen storage system.

[0016] In combination with the first aspect, the embodiment of the present invention provides a fourth possible implementation of the first aspect, wherein the method further includes:

[0017] The number of times the hydrogen storage system is charged and discharged is recorded according to the count value of the counter.

[0018] In combination with the first aspect, an embodiment of the present invention provides a fifth possible implementation of the first aspect, wherein, before the step of determining the fault type of the hydrogen storage system based on a comparison result of the high pressure with the second preset pressure threshold if the intermediate pressure is lower than a third preset pressure threshold, the method further includes:

[0019] After the hydrogen storage system is loaded onto a vehicle and rolled off the production line, nitrogen is first filled into the gas cylinder of the hydrogen storage system for a preset number of times, and then the nitrogen in the gas cylinder is replaced with hydrogen to achieve a pure hydrogen environment inside the hydrogen storage system.

[0020] In combination with the first aspect, the embodiment of the present invention provides a sixth possible implementation of the first aspect, wherein the method further includes:

[0021] When it is detected that the high pressure of the hydrogen storage system exceeds a first preset pressure threshold and a fault exists in the hydrogen storage system, an alarm is directly issued for the fault existing in the hydrogen storage system.

[0022] In a second aspect, an embodiment provides an electronic device comprising a memory and a processor, wherein the memory stores a computer program that can be run on the processor, and when the processor executes the computer program, the steps of the method described in any of the aforementioned embodiments are implemented.

[0024] Embodiments of the present invention provide a post-offline hydrogenation control method and electronic device for a hydrogen storage system. Based on the comparison results of the high-pressure and medium-pressure detection values ​​during the hydrogenation and replacement process of the hydrogen storage system with their corresponding preset pressure thresholds, the fault type of the current abnormal pressure fault can be determined. A second fault type is a pressure change abnormality that occurs during the hydrogenation and replacement process. If a fault is determined based on the pressure change, a false alarm may occur. However, this second fault is merely a pressure change abnormality and does not affect hydrogenation safety. An alarm is only issued when the counter value reaches the preset count threshold, i.e., when this second fault occurs after the hydrogenation and replacement process is completed, to ensure alarm reliability. It should be noted that if the pressure change abnormality recurs after the hydrogenation and replacement process is completed, it is not caused by the hydrogenation and replacement, but is a fault that affects system safety and requires an alarm. The first fault is a fault in a hydrogen storage system component, which affects hydrogenation safety and needs to be directly reported regardless of whether the hydrogenation and replacement process is completed. This hydrogenation control strategy avoids false alarms while promptly reporting faults that affect hydrogenation reliability.

[0025] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Hydrogen energy technology is an important direction of technological development, involving a wide range of fields, such as hydrogen storage systems in automobiles (passenger cars, commercial vehicles, special vehicles), ships, bicycles and other fields.

[0034] The hydrogen storage system consists of hydrogen storage bottles, bottle valves, high-pressure pipelines, pressure reducing valves, medium-pressure pipelines, hydrogen system controllers (HMS), infrared controllers, etc.

[0035] During the replacement process, the gas to be replaced is injected into the hydrogen storage system through the hydrogen filling port, and then the gas in the hydrogen storage system is released, and then filled again. The internal gas environment of the hydrogen storage system is completed through multiple filling and releasing processes.

[0036] Currently, after the hydrogen storage system is loaded and rolled off the production line, the work of hydrogen storage system replacement and hydrogenation is to shield the related faults of low high pressure and low medium pressure; among them, high pressure is the gas pressure in the gas cylinder, and medium pressure is the pressure in the pipeline after the pressure reducing valve; that is, from the time the vehicle is rolled off the production line to the time of replacement and hydrogenation, the pressure in the pipeline after the pressure reducing valve (medium pressure) is atmospheric pressure, and the high-pressure gas in the gas cylinder needs to be exhausted during the replacement process. The high-pressure pressure sensor and medium-pressure sensor of the hydrogen storage system are used to measure and compare with the corresponding set thresholds. In this case, the high-pressure and medium-pressure pressures will be lower than the fault thresholds. In order to avoid such false alarms, the relevant faults are shielded so that the hydrogen system controller HMS does not alarm for medium-pressure faults and high-pressure faults.

[0037] However, the above-mentioned fault shielding operation will cause some faults that need to be alarmed during the replacement process to not be alarmed; for example, if the medium pressure is lower than 1MPa and the remaining hydrogen volume is not lower than the preset hydrogen volume threshold value empty, then the hydrogen system controller HMS should record the pressure and hydrogen volume values ​​and send an error fault, but because the fault shielding operation cannot correctly report the error fault, it will affect the reliability judgment of the hydrogen storage system.

[0038] Based on this, an embodiment of the present invention provides a hydrogen refueling control method and electronic equipment after a hydrogen storage system is offline, which can avoid false alarms while alarming necessary faults that affect system safety, thereby improving hydrogen refueling reliability.

[0039] To facilitate understanding of this embodiment, a method for controlling hydrogenation after a hydrogen storage system is offline disclosed in an embodiment of the present invention is first introduced in detail. This method can be applied to intelligent control devices such as fuel cell system controllers and hydrogen storage system controllers.

[0040] Figure 1 A flow chart of a hydrogenation control method after a hydrogen storage system is offline is provided for an embodiment of the present invention.

[0041] Reference Figure 1 , the method may include the following steps:

[0042] Step S102: Acquire the pressure detection value of the hydrogen storage system.

[0043] The pressure detection value includes high pressure and medium pressure.

[0044] Here, the pressure of the hydrogen storage system can be detected by sensing equipment, including detecting the high pressure and medium pressure respectively; the high pressure is the gas pressure in the gas cylinder in the hydrogen storage system, and the medium pressure is the gas pressure in the outlet pipeline of the pressure reducing valve in the hydrogen storage system.

[0045] In step S104 , if it is detected that the high pressure of the hydrogen storage system is lower than the first preset pressure threshold and higher than the second preset pressure threshold, and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, the fault type of the hydrogen storage system is the first fault.

[0046] It should be noted that if the high pressure of the hydrogen storage system is higher than the second preset pressure threshold, it can be considered that the remaining hydrogen amount of the hydrogen storage system is not lower than the preset hydrogen amount threshold, which is a first fault.

[0047] Among them, the remaining hydrogen amount of the hydrogen storage system can be determined by looking up the high-pressure pressure collected by the current high-pressure pressure sensor and the current temperature in the table to determine the hydrogen density value of the hydrogen storage system at this time, and then the remaining hydrogen amount of the hydrogen storage system can be determined based on the container volume corresponding to the hydrogen storage system and the hydrogen density value.

[0048] Step S106: If it is detected that the high pressure of the hydrogen storage system is lower than the second preset pressure threshold and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, the fault type of the hydrogen storage system is the second fault;

[0049] Among them, the fault type includes the second fault and the first fault. The second fault can be understood as a fault caused by the pressure change generated during the hydrogenation replacement process and the difference between the various pressures; the high pressure and medium pressure fluctuations in the hydrogenation replacement process will be lower than the fault threshold. During the replacement hydrogenation process, it is necessary to avoid false alarms caused by such pressures being lower than the threshold; the second fault is just an abnormal pressure change phenomenon, which belongs to the false alarm fault type caused by hydrogenation replacement. It does not affect the safety of hydrogenation replacement, and no alarm is required during the hydrogenation replacement process; it should be noted that if abnormal pressure changes occur after the hydrogenation replacement is completed, the abnormal pressure change at this time is not a result of the hydrogenation replacement. If it is caused by a hydrogen replacement, it is a fault that will affect the safety of the system and needs to be alarmed; in other words, this fault will alarm after the hydrogenation replacement process is completed; and the first fault can be understood as a fault caused by the components of the hydrogen storage system itself, which affects the hydrogenation reliability of the hydrogen storage system; for example, it refers to the hydrogen storage system hydrogen storage temperature (hydrogen temperature in the hydrogen bottle, bottle valve temperature), high pressure (hydrogen pressure in the hydrogen bottle, bottle valve pressure, high-pressure pipeline pressure), medium pressure (pressure from the pressure reducing valve to the fuel cell stack), hydrogen leakage, sensor (sensor abnormality) and other faults due to system component failure during normal system operation; such faults must be reported directly regardless of whether they are in the hydrogenation replacement process.

[0050] Step S108: If the fault type is the first fault, directly alarm the first fault.

[0051] Step S110: If the fault type is the second fault, no alarm is given when the hydrogenation replacement process of the hydrogen storage system is not completed; when the hydrogenation replacement process of the hydrogen storage system is completed, an alarm is given for the second fault.

[0052] When the count value of the counter is greater than a preset count threshold, the hydrogenation replacement process of the hydrogen storage system is completed. In some embodiments, if a preset condition is triggered, the counter is counted.

[0053] Exemplarily, if in response to a hydrogenation request, the high-pressure pressure of the hydrogen storage system increases, and the high-pressure pressure does not exceed a first preset pressure threshold, the preset condition is triggered, and the count value of the counter is controlled to increase by one; at this time, the number of times the hydrogen storage system is filled and discharged can be recorded according to the count value of the counter, and it can also be determined whether the hydrogenation process of the hydrogen storage system is completed; if the count value of the counter is greater than the preset count threshold, the hydrogenation replacement process of the hydrogen storage system is completed, otherwise, the hydrogenation replacement process is not completed.

[0054] As an optional embodiment, a method for determining an increasing trend in the high-pressure pressure of a hydrogen storage system includes: recording and storing the high-pressure pressure value corresponding to a preset time period currently collected by the hydrogen storage system, overwriting the high-pressure pressure value corresponding to the previous preset time period; and comparing the high-pressure pressure values ​​corresponding to the initial time point and the end time point of the currently collected preset time period to determine whether the high-pressure pressure of the hydrogen storage system is showing an increasing trend. For example, if the preset time period is 1 minute, the high-pressure pressure value of the hydrogen storage system collected for the current 1 minute is first overwritten with the high-pressure pressure value collected for the previous 1 minute, and then the high-pressure pressures corresponding to the 1st second and the 60th second of the current 1 minute are compared; if the high-pressure pressure corresponding to the 60th second is greater than the high-pressure pressure corresponding to the 1st second, then the high-pressure pressure of the hydrogen storage system is showing an increasing trend; and vice versa.

[0055] In a preferred embodiment of actual application, based on the comparison results of the detection values ​​of the high pressure and the medium pressure during the hydrogenation and replacement process of the hydrogen storage system and the corresponding preset pressure thresholds, it is possible to know what type of fault the current pressure abnormality fault belongs to; for the second fault type, it is a pressure change abnormality that will occur during the hydrogenation and replacement process, which will not affect the safety of hydrogenation, and an alarm is only required when the counter count value reaches the preset count threshold, that is, when this type of second fault still occurs after the hydrogenation and replacement process is completed; and for the first fault, it is a situation where there is a fault in the hydrogen storage system component, which will affect the safety of hydrogenation, and the fault must be reported directly regardless of whether the hydrogenation and replacement process is completed at this time; through the above-mentioned hydrogenation control strategy, the purpose of avoiding false alarms while reporting faults that affect the reliability of hydrogenation in a timely manner is achieved.

[0056] It should be noted that, before step S102, the method further includes:

[0057] Step 1.1): After the hydrogen storage system is loaded onto a vehicle and rolled off the production line, nitrogen is first filled into the gas cylinder of the hydrogen storage system for a preset number of times, and then the nitrogen in the gas cylinder is replaced with hydrogen to achieve a pure hydrogen environment inside the hydrogen storage system.

[0058] Because the hydrogen storage system will be loaded and unloaded after the hydrogen storage bottle is replaced and refilled with hydrogen, the air in the bottle will be replaced with nitrogen in the first few times, and then the nitrogen in the bottle will be replaced with hydrogen, so that the inside of the hydrogen storage system is a pure hydrogen environment.

[0059] In actual application, when it is detected that the high pressure of the hydrogen storage system exceeds the first preset pressure threshold and there is a fault in the hydrogen storage system, an alarm is directly issued for the fault in the hydrogen storage system.

[0060] If it is detected that the high pressure of the hydrogen storage system exceeds the first preset pressure threshold, the fault broadcast code is activated at this time. In this activated state, if there is a fault in the hydrogen storage system, an alarm will be directly issued without considering the fault type of the hydrogen storage system.

[0061] Among them, the first preset pressure threshold refers to a set high-pressure value. If the high-pressure value is exceeded, it is considered that the direct fault alarm function of the hydrogen storage system is activated; the second preset pressure threshold refers to a fault high-pressure pressure threshold lower than the normal high-pressure pressure. If it is lower than this fault high-pressure pressure threshold, a high-pressure low fault is reported; the third preset pressure threshold refers to a fault medium-pressure pressure threshold lower than the normal medium-pressure pressure. If it is lower than this value, a medium-pressure low fault is reported; the first preset pressure threshold is greater than the second preset pressure threshold;

[0062] The embodiment of the present invention adds a counter to the control logic of the hydrogen storage system. When performing the charging and discharging operation, each charging will respond to a hydrogenation request. The high-pressure pressure value will increase each time the charging is performed. At the same time, a technical judgment is made based on the response to the hydrogenation request and the degree of increase in the high-pressure pressure. If both are met, the counter counts once to avoid only responding without actually performing the hydrogenation operation. The counter reading can also intuitively record the number of charging and discharging times during the hydrogen replacement process. When the count value recorded by the counter reaches the preset number threshold, it is considered that the hydrogen replacement is completed.

[0063] Sometimes, during the replacement process, more gas will be added. For the sake of system safety and stability, the embodiment of the present invention sets a first preset pressure threshold for high pressure. If the high pressure of the hydrogen storage system is higher than the first preset pressure threshold, the fault alarm function will be activated regardless of whether the number of replacements has been reached. Thereafter, when any fault occurs in the hydrogen storage system again, an alarm will be issued.

[0064] Here, the failure of the hydrogen storage system can be understood as a situation where the comparison results of parameters such as temperature, high pressure, medium pressure, etc. detected by the corresponding sensors of the hydrogen storage system and their corresponding thresholds do not meet the requirements.

[0065] At the same time, when performing fault judgment on the medium pressure and high pressure, the counter number judgment will be performed synchronously. Only when the counter number is greater than the preset number threshold can it be reported normally to avoid false alarms during the replacement process. However, if the medium pressure is lower than the third preset pressure threshold and the remaining hydrogen amount is not lower than the preset hydrogen amount threshold (the high pressure of the hydrogen storage system is higher than the second preset pressure threshold), the fault can be reported directly without counter judgment.

[0066] Figure 2 Another hydrogenation control flow chart of a hydrogen storage system after it is offline is provided for an embodiment of the present invention.

[0067] like Figure 2As shown, the hydrogen storage system performs a self-test operation; when a hydrogenation request has been received, the output is 1 in response to the hydrogenation request; if the high pressure is not greater than the first preset pressure threshold, such as 10MPa, the output is 1; if the high pressure is in an increasing state, the output is 1; when the output of the above three situations is 1, the counter count is increased by 1; if the high pressure detected by the high pressure pressure sensor is lower than the second preset pressure threshold, and if the medium pressure detected by the medium pressure sensor is lower than the third preset pressure threshold, it is determined whether the counter count value at this time is greater than the preset count threshold, that is, the calibration threshold; if it is greater, the fault will be reported; otherwise, no error will be reported for such faults; or, when the medium pressure is lower than the third preset pressure threshold and the remaining hydrogen amount is not lower than the entry preset hydrogen amount threshold (the high pressure pressure of the hydrogen storage system is higher than the second preset pressure threshold), the value should be recorded and an error fault should be sent; wherein, the third preset pressure threshold can be selected as 1MPa, and the preset hydrogen amount threshold can be understood as the empty threshold. In addition, when the high pressure is greater than the first preset pressure threshold, if there is a fault in the hydrogen storage system, a fault error is directly reported without considering the type of fault.

[0068] The embodiment of the present invention adds a counter to the control logic of the hydrogen storage system. The counter can not only intuitively record the number of times of filling and discharging, but also avoid false alarms caused by pressure fluctuations during the hydrogen replacement process of the gas cylinder.

[0069] In some embodiments, as Figure 3 As shown, an embodiment of the present invention further provides a hydrogenation control device after the hydrogen storage system is offline, comprising:

[0070] An acquisition module is used to acquire a pressure detection value of the hydrogen storage system, wherein the pressure detection value includes a high pressure and a medium pressure;

[0071] The determination module determines that if it is detected that the high pressure of the hydrogen storage system is lower than the first preset pressure threshold and higher than the second preset pressure threshold, and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, then the fault type of the hydrogen storage system is a first fault; if it is detected that the high pressure of the hydrogen storage system is lower than the second preset pressure threshold and the medium pressure of the hydrogen storage system is lower than the third preset pressure threshold, then the fault type of the hydrogen storage system is a second fault.

[0072] a first control module, directly alarming the first fault if the fault type is the first fault;

[0073] The second control module, if the fault type is the second fault, does not alarm when the hydrogenation replacement process of the hydrogen storage system is not completed; when the hydrogenation replacement process of the hydrogen storage system is completed, it alarms for the second fault.

[0075] In some embodiments, the device is further specifically configured to trigger a preset condition and control the count value of the counter to increase by one if, in response to a hydrogen refueling request, the high pressure of the hydrogen storage system increases and the high pressure does not exceed a first preset pressure threshold.

[0076] In some embodiments, the high pressure is the gas pressure in the gas cylinder in the hydrogen storage system, and the medium pressure is the gas pressure in the outlet pipeline of the pressure reducing valve in the hydrogen storage system.

[0077] In some embodiments, the device is further specifically configured to record the number of times the hydrogen storage system is charged and discharged according to the count value of the counter.

[0078] In some embodiments, before the step of determining the fault type of the hydrogen storage system based on the pressure detection value of the hydrogen storage system, the device is also used to, after the hydrogen storage system is loaded and offline, first fill nitrogen into the gas cylinder of the hydrogen storage system for a preset number of times, and then replace the nitrogen in the gas cylinder with hydrogen to achieve a pure hydrogen environment inside the hydrogen storage system.

[0079] In some embodiments, the device is further specifically configured to directly alarm the hydrogen storage system for the fault when it is detected that the high pressure of the hydrogen storage system exceeds a first preset pressure threshold and the hydrogen storage system has a fault.
