Description

Technical Field

[0001] This disclosure relates to the field of new energy, and more specifically, to a method, apparatus, storage medium, and electronic device for hydrogen refueling control. Background Technology

[0002] With the widespread application of new energy sources, hydrogen, as a clean energy source, has also been widely used. However, existing methods of hydrogen refueling via hydrogen dispensers suffer from pressure drop due to resistance in valves and other piping components. This necessitates maintaining a certain pressure difference between the gas source and the dispenser outlet to achieve a constant pressurization rate, which reduces the utilization rate of the hydrogen from the gas source.

[0003] In addition, in existing hydrogen refueling control methods, in order to maintain a constant pressure increase rate, when the pressure difference between the gas source and the outlet of the hydrogen dispenser is large at the beginning, the flow cross-sectional area of ​​the pressure regulating valve is small, the fluid pressure drop is large, and the throttling effect is large, which leads to a more significant rise in hydrogen temperature at the outlet of the hydrogen dispenser, thus hindering rapid hydrogen refueling.

[0004] Furthermore, during the hydrogen refueling process, since there is a one-to-one correspondence between the target pressure and the pressurization rate, once the pressurization rate deviates from the fluctuation range, it is impossible to give a new target pressure for refueling, and refueling can only be stopped, reducing refueling efficiency.

[0005] In summary, existing hydrogenation control methods have significant flaws in both control methods and structure, resulting in low efficiency in both hydrogen utilization and hydrogenation. Summary of the Invention

The preset condition indicates that the real-time flow rate in the hydrogenation pipeline is less than or equal to the target flow rate corresponding to the hydrogenation pipeline by a first preset multiple. If the real-time flow rate of the hydrogenation pipeline meets the preset condition corresponding to the hydrogenation pipeline, the hydrogenation pipeline is determined to be the target hydrogenation pipeline.

[0024] Optionally, before determining whether the real-time flow rate of one or more of the hydrogenation pipelines meets the preset conditions, the pipeline determination module is further configured to stop hydrogenation of the target object to be hydrogenated if the real-time flow rate is greater than or equal to the target flow rate of the second preset multiple, wherein the second preset multiple is greater than the first preset multiple.

[0028] Fourthly, this disclosure provides an electronic device, comprising: a memory storing a computer program thereon; and a processor for executing the computer program in the memory to implement the steps of the above method.

[0029] The above technical solution involves acquiring the target flow rate, real-time flow rate, real-time outlet pressure, and preset hydrogen refueling pressure. Based on the real-time outlet pressure, a target gas source is determined from one or more gas sources with different pressures. Based on the target flow rate and the real-time flow rate, a target hydrogen refueling pipeline is determined from one or more hydrogen refueling pipelines with different resistances. Hydrogen is then refueled to the target object using the target gas source and the target hydrogen refueling pipeline. Hydrogen refueling is stopped when the real-time outlet pressure is greater than or equal to the preset hydrogen refueling pressure. By judging the real-time flow rate of the hydrogen refueling pipeline and selecting hydrogen refueling pipelines with different resistances, the utilization efficiency of the hydrogen source is improved, the impact of the throttling effect is reduced, and the temperature rise during refueling is lowered, thereby increasing the refueling rate and shortening the refueling time. Simultaneously, by using the real-time flow rate, real-time enthalpy value, and initial hydrogen refueling parameters of the hydrogen refueling pipeline, the preset hydrogen refueling pressure of the target object is obtained in real time, and the hydrogen refueling completion state is dynamically adjusted, improving the flexibility of the refueling process control and the hydrogen fill level of the target object.

[0030] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0031] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings:

[0032] Figure 1 This is a flowchart illustrating a hydrogenation control method according to an exemplary embodiment;

[0033] Figure 2 This is a block diagram of a hydrogenation control device according to an exemplary embodiment;

[0034] Figure 3 This is an electronic device illustrated according to an exemplary embodiment. Detailed Implementation

[0035] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0036] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0037] First, the application scenario of this disclosure is explained. This disclosure is applied to the scenario of hydrogen refueling control. In existing hydrogen refueling control methods, a certain pressure difference must be maintained between the gas source and the outlet of the hydrogen dispenser to achieve stable hydrogen refueling. Moreover, the method of adjusting the pressure difference is to control the flow cross-sectional area of ​​the fluid through the valve body by controlling the pressure difference through a pressure regulating valve. Because a constant pressure increase rate needs to be maintained during the initial hydrogen refueling process, the fluid pressure drop across the pressure regulating valve is large, resulting in a large throttling effect and a significant temperature rise of the hydrogen at the outlet of the hydrogen dispenser, leading to relatively low hydrogen utilization efficiency and hydrogen refueling efficiency. In addition, in existing hydrogen refueling control methods, there is a one-to-one correspondence between the pressure of the target object to be hydrogenated and the pressure increase rate. When the pressure increase rate deviates from the fluctuation range, refueling needs to be stopped, resulting in a low filling degree of the target object.

[0038] To address the aforementioned problems, this disclosure provides a method, apparatus, storage medium, and electronic device for hydrogen refueling control. The method includes: acquiring a target flow rate, real-time flow rate, real-time outlet gas pressure, and a preset hydrogen refueling pressure; determining a target gas source from one or more gas sources with different pressures based on the real-time outlet gas pressure; determining a target hydrogen refueling pipeline from one or more hydrogen refueling pipelines with different resistances based on the target flow rate and the real-time flow rate; refueling the target object with hydrogen through the target gas source and the target hydrogen refueling pipeline; and stopping hydrogen refueling of the target object when the real-time outlet gas pressure is greater than or equal to the preset hydrogen refueling pressure. Thus, by determining the magnitude of the real-time flow rate of the hydrogen refueling pipeline and selecting hydrogen refueling pipelines with different resistances, it is beneficial to improve the utilization efficiency of the hydrogen source, reduce the impact of throttling effects, lower the refueling temperature rise, thereby increasing the refueling rate and shortening the refueling time. Meanwhile, by using the real-time flow rate, real-time enthalpy value, and initial hydrogenation parameters of the hydrogenation pipeline, the preset hydrogenation pressure of the target object can be obtained in real time, and the hydrogenation completion status can be dynamically adjusted to improve the flexibility of the refueling process control and the hydrogen filling degree of the target object.

[0039] The present disclosure will now be described in conjunction with specific embodiments.

[0040] Figure 1 This application illustrates a method for controlling hydrogenation according to an exemplary embodiment, such as... Figure 1 As shown, the method includes:

[0041] S101. Obtain the target flow rate, real-time flow rate, real-time outlet pressure, and preset hydrogen filling pressure for hydrogen addition.

[0042] The real-time flow rate and real-time outlet gas pressure can be obtained through relevant measuring devices preset in the hydrogen dispenser, such as flow meters and pressure gauges. The target flow rate is a different flow limit value corresponding to different initial hydrogen dispensing parameter conditions under the hydrogen dispensing control method of this application, which ensures that the target object does not exceed the temperature, pressure, or charge limits. It is used to characterize the flow judgment threshold in the hydrogen dispensing pipeline of the hydrogen dispenser. Therefore, the target flow rate can be the target average flow rate in the hydrogen dispensing pipeline, or it can be the target maximum flow rate or target minimum flow rate allowed by the hydrogen dispensing pipeline. Here, the target average flow rate is used as an example for explanation. The target average flow rate for hydrogen dispensing can be obtained as follows:

[0043] First, the initial hydrogenation parameters of the target object are obtained. In this step, the initial hydrogenation parameters of the target object to be hydrogenated can be obtained by the hydrogenation pulse preset by the hydrogenation machine. The initial hydrogenation parameters include the volume of the target object, the initial pressure, and the ambient temperature.

[0044] Secondly, the first average flow rate is determined based on the initial hydrogenation parameters and the preset hydrogenation time;

[0045] Next, based on the initial hydrogenation parameters, the preset hydrogenation time, and the preset deviation, the second average flow rate and the third average flow rate are determined. In this step, since the volume measurement is allowed to have a deviation of ±15%, the theoretically allowed maximum average hydrogenation flow rate, namely the second average flow rate and the third average flow rate, is obtained based on the measurement deviation boundary volume.

[0046] Finally, the target average flow rate is determined based on the first average flow rate, the second average flow rate, and the third average flow rate. In this step, since the higher the flow rate during hydrogenation, the higher the temperature of the hydrogen, and hydrogen energy has a high degree of danger, hydrogen in a confined environment can explode when the temperature is close to the ignition point. Therefore, the minimum value among the first average flow rate, the second average flow rate, and the third average flow rate is determined as the target average flow rate to ensure sufficient safety.

[0047] Furthermore, the target flow rate can be determined based on the initial hydrogenation parameters. For example, the target flow rate can be determined based on a preset parameter flow rate correspondence. For instance, the initial hydrogenation parameters of the target object can be sent to a server via a communication device, so that the server can determine the target flow rate based on the preset parameter flow rate correspondence and receive the target flow rate sent by the server via the communication device.

[0048] It should be noted that users can select one or more of the target average flow rate, the target maximum flow rate, or the target minimum flow rate as the flow rate judgment threshold in the hydrogen refueling pipeline, based on their needs or actual conditions.

[0049] S102. Based on the real-time outlet air pressure, determine the target air source from one or more air sources with different air pressures.

[0050] For example, to determine the target gas source from one or more gas sources with different pressures, the first step is to obtain the pressure of one or more of these gas sources; different gas sources correspond to different pressures. Then, the pressures of one or more of these gas sources are compared sequentially with the real-time outlet pressure according to a preset gas source order; this preset gas source order can be arranging one or more gas sources in ascending order of their pressure. Finally, if a first gas source pressure is greater than the real-time outlet pressure, that first gas source is determined as the target gas source; this can be done by comparing the pressures of one or more of these gas sources sequentially with the real-time outlet pressure according to the preset gas source order, in ascending order. Since the outlet of the hydrogen dispenser is connected to the target object to be hydrogenated, the real-time outlet pressure is the same as the pressure of the target object to be hydrogenated.

[0051] In this way, selecting a suitable gas source based on the target object to be hydrogenated is beneficial to improving the utilization rate of the hydrogen source.

[0052] In addition, before determining the target gas source, different methods need to be prioritized because the initial hydrogenation parameters of the target object to be hydrogenated are different.

[0053] For example, based on the initial hydrogenation parameters of the target object, it is determined whether pre-cooling is required; if pre-cooling is required, the pre-cooling temperature is determined based on the initial hydrogenation parameters and pre-cooling is performed.

[0054] For example, if the initial ambient temperature of the target object is high, in order to prevent the temperature from rising above the safe temperature threshold of hydrogen during the hydrogenation process, which could lead to a dangerous accident, the target object is pre-cooled to reduce its temperature to below the standard temperature threshold for hydrogenation.

[0055] This can avoid potential dangerous accidents and further improve the safety of hydrogenation.

[0056] S103. Based on the target flow rate and the real-time flow rate, determine the target hydrogen refueling pipeline from one or more hydrogen refueling pipelines with different resistances.

[0057] Different hydrogen refueling pipelines correspond to different fluid resistances. These pipelines can utilize a combination of static components with specific resistance characteristics, including orifice plates, valves, and filters. The selection of the size and specifications of these static components is based on two criteria: First, when hydrogen refueling is conducted through any hydrogen refueling pipeline containing a static component, the maximum instantaneous flow rate of that pipeline must not exceed the maximum permissible flow rate threshold under full gas supply conditions. Second, when hydrogen refueling is conducted through any hydrogen refueling pipeline containing a static component, the maximum hydrogen refueling time must not exceed the maximum permissible refueling time under full gas supply conditions. This maximum permissible refueling time can be set according to requirements. These two limitations can be achieved using a single component or by combining multiple components in series or parallel; this disclosure does not impose any restrictions on this.

[0058] In this way, during the process of adding hydrogen to the target object through the target hydrogenation pipeline, the resistance of the target hydrogenation pipeline remains unchanged. As the gas pressure of the target object increases, the hydrogen flow rate first increases and then decreases. The hydrogen at the outlet of the hydrogen dispenser heats up significantly at the beginning, and then the temperature rise gradually decreases as the flow rate decreases. This prolongs the heat dissipation time of the hydrogen at the outlet, which is beneficial to the control of hydrogen temperature rise and reduces the impact of the throttling effect.

[0059] In one possible implementation, based on the resistance, the real-time flow rate of one or more hydrogen refueling pipelines can be sequentially determined according to a preset resistance order to see if they meet preset conditions. If the real-time flow rate of a hydrogen refueling pipeline meets the preset conditions corresponding to that pipeline, the hydrogen refueling pipeline is identified as the target hydrogen refueling pipeline. Here, the preset conditions indicate that the real-time flow rate in the hydrogen refueling pipeline is greater than or equal to a target flow rate that is a first preset multiple of the flow rate of the hydrogen refueling pipeline.

[0060] For example, one or more hydrogen refueling pipelines are arranged in a preset order of decreasing resistance according to the magnitude of the resistance, and the hydrogen refueling pipeline with the highest resistance among the one or more hydrogen refueling pipelines is designated as the first hydrogen refueling pipeline. The target gas source is connected to the target object to be hydrogenated through the first hydrogen refueling pipeline so that the target gas source can refuel the target object with hydrogen.

[0061] The first real-time flow rate during the hydrogenation process within a preset time period is obtained. If the first real-time flow rate is greater than or equal to the target flow rate corresponding to the first preset multiple of the first hydrogenation pipeline, it is determined that the first hydrogenation pipeline meets the preset conditions, and hydrogenation continues to be applied to the target object through the first hydrogenation pipeline. If the first real-time flow rate is less than the target flow rate corresponding to the first preset multiple of the first hydrogenation pipeline, it is determined that the first hydrogenation pipeline does not meet the preset conditions.

[0062] Then, based on the preset resistance order, one or more second hydrogenation pipelines are determined, that is, hydrogenation pipelines whose fluid resistance is second only to the first hydrogenation pipeline. The target gas source is connected to the target object to be hydrogenated through the second hydrogenation pipeline so that the target gas source can hydrogenate the target object. If the second real-time flow rate in the second hydrogenation pipeline is greater than or equal to the second preset flow rate threshold corresponding to the second hydrogenation pipeline, it is determined that the second hydrogenation pipeline meets the preset conditions, and hydrogenation of the target object continues through the second hydrogenation pipeline. If the second real-time flow rate is less than the second preset flow rate threshold, it is determined that the second hydrogenation pipeline does not meet the preset conditions.

[0063] Additionally, it should be noted that before determining whether the real-time flow rate of one or more of the hydrogen refueling pipelines meets the preset conditions, it is necessary to first determine whether the real-time flow rate of the hydrogen refueling pipeline is greater than the target flow rate of the second preset multiple. If the real-time flow rate of the hydrogen refueling pipeline is greater than or equal to the target flow rate of the second preset multiple, hydrogen refueling of the target object to be hydrogenated shall be stopped, wherein the second preset multiple is greater than the first preset multiple.

[0064] For example, when the target gas source is connected to the target object to be hydrogenated through the first hydrogenation pipeline, if the first real-time flow rate is greater than or equal to twice the target flow rate, the first real-time flow rate is too high, which may cause the hydrogen temperature at the outlet of the hydrogen dispenser to be too high, thereby causing a dangerous accident. Therefore, hydrogenation to the target object is stopped.

[0065] In this way, by coupling one or more hydrogen refueling pipelines with the target gas source, the pressure difference between the gas source and the real-time outlet gas pressure of the hydrogen refueling machine is effectively utilized, increasing the utilization rate of hydrogen from the gas source, reducing the impact of the throttling effect, resulting in a smaller temperature rise of the target object and saving pre-cooling energy consumption.

[0066] In addition, based on the above-mentioned determination of the target hydrogen refueling pipeline, and by analogy, according to the preset resistance sequence, if the real-time flow rate of the last hydrogen refueling pipeline in one or more hydrogen refueling pipelines does not meet the preset conditions corresponding to the hydrogen refueling pipeline, according to the preset gas source sequence, the next gas source of the first gas source is determined as the new first gas source, and the new first gas source is determined as the target gas source.

[0067] For example, the gas pressure of the target object will continuously rise during the hydrogenation process. If the last hydrogenation pipeline in one or more hydrogenation pipelines does not meet the preset conditions, it indicates that the gas pressure of the target gas source is insufficient to hydrogenate the target object. Therefore, according to the preset gas source sequence, the next gas source is determined as the new target gas source, and the new target gas source is connected to the target object through the first hydrogenation pipeline, so that the new target gas source can hydrogenate the target object sequentially through the hydrogenation pipeline according to the preset resistance sequence.

[0068] In this way, by coupling one or more hydrogen refueling pipelines with one or more gas sources, the pressure difference between the gas source and the target object is effectively utilized, increasing the utilization rate of hydrogen from the gas source, while reducing the impact of the throttling effect, thereby resulting in a smaller temperature rise of hydrogen in the target object and saving pre-cooling energy consumption.

[0069] S104. Hydrogen is added to the target object through the target gas source and the target hydrogenation pipeline.

[0070] S105. If the real-time outlet gas pressure is greater than or equal to the preset hydrogenation gas pressure, stop adding hydrogen to the target object to be hydrogenated.

[0071] In this step, it is important to note that a preset hydrogen filling pressure needs to be obtained. This preset hydrogen filling pressure represents the maximum hydrogen filling pressure for the target object. Hydrogen filling is stopped when the real-time outlet pressure is greater than or equal to the preset hydrogen filling pressure. This preset hydrogen filling pressure can be adjusted and set in real-time during the filling process based on parameters such as real-time flow rate, real-time pressure, and hydrogen temperature. For example, the outlet temperature of the hydrogen dispenser is obtained in real-time via a hydrogen filling pulse. Based on the real-time outlet pressure and outlet temperature, the real-time enthalpy is determined. Then, the average enthalpy is determined based on the real-time enthalpy, the real-time flow rate, and the preset hydrogen filling time, as shown below: Among them, h ave Here, represents the average enthalpy, t represents the preset hydrogenation time, h represents the real-time enthalpy, and F represents the real-time flow rate. The actual average flow rate is then determined based on this real-time flow rate and the preset hydrogenation time, as shown below. in, The average flow rate is represented by , and F represents the real-time flow rate. Finally, the preset hydrogenation pressure is determined based on the average enthalpy, the average flow rate, and the initial hydrogenation parameters.

[0072] The above scheme involves acquiring the target flow rate, real-time flow rate, and real-time outlet pressure of hydrogen refueling; determining the target gas source from one or more gas sources with different pressures based on the real-time outlet pressure; determining the target hydrogen refueling pipeline from one or more hydrogen refueling pipelines with different resistances based on the target flow rate and the real-time flow rate; and then refueling the target object using the target gas source and the target hydrogen refueling pipeline. By determining the real-time flow rate of the hydrogen refueling pipeline and selecting hydrogen refueling pipelines with different resistances, the utilization efficiency of the hydrogen source is improved, the impact of the throttling effect is reduced, and the temperature rise during refueling is lowered, thereby increasing the refueling rate and shortening the refueling time. Simultaneously, by using the real-time flow rate, real-time enthalpy value of the hydrogen refueling pipeline, and the initial hydrogen refueling parameters of the target object, the preset hydrogen refueling pressure of the target object can be obtained in real time, and the hydrogen refueling completion state can be dynamically adjusted, improving the flexibility of the refueling process control and the hydrogen fill level of the target object.

Based on the real-time outlet gas pressure, a target gas source is determined from one or more gas sources with different pressures. Based on the target flow rate and the real-time flow rate, a target hydrogen refueling pipeline is determined from one or more hydrogen refueling pipelines with different resistances. Hydrogen is then refueled to the target object using the target gas source and the target hydrogen refueling pipeline. Hydrogen refueling is stopped when the real-time outlet gas pressure is greater than or equal to the preset hydrogen refueling pressure. By determining the real-time flow rate of the hydrogen refueling pipeline and selecting hydrogen refueling pipelines with different resistances, the utilization efficiency of the hydrogen source is improved, the impact of the throttling effect is reduced, and the temperature rise during refueling is lowered, thereby increasing the refueling rate and shortening the refueling time. Simultaneously, by using the real-time flow rate, real-time enthalpy value of the hydrogen refueling pipeline, and the initial hydrogen refueling parameters of the target object, the preset hydrogen refueling pressure of the target object can be obtained in real time, and the hydrogen refueling completion state can be dynamically adjusted, improving the flexibility of the refueling process control and the hydrogen fill level of the target object.
