Description

Technical Field

[0001] This disclosure relates to the field of hydrogen storage technology, specifically to a control method, apparatus, storage medium, and electronic equipment for a hydrogen refueling station. Background Technology

[0002] Currently, the technology for on-board high-pressure hydrogen storage tanks is mature and highly safe. Hydrogen refueling time is comparable to that of gasoline and diesel vehicles, and it generally needs to be done at a hydrogen refueling station.

[0003] Normally, when refueling an on-board hydrogen storage system, hydrogen is drawn from the storage cylinders in order of low pressure to high pressure, and the cylinders are switched when the pressure of a particular cylinder falls below the pressure of the on-board hydrogen storage container. Simultaneously, the compressor replenishes hydrogen from the storage cylinders in order of high pressure to low pressure, and switches back to the storage cylinders when the pressure of a particular cylinder reaches its full load pressure. However, during this refueling and replenishment process, the pressure of the low-pressure storage cylinders may sometimes exceed that of the high-pressure storage cylinders, resulting in insufficient utilization of the high-pressure hydrogen and thus reducing the refueling capacity.

[0090] 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.

[0091] Before detailing the specific embodiments of this disclosure, its application scenarios will first be explained. This disclosure can be applied to hydrogen refueling control scenarios at hydrogen refueling stations. Currently, on-board high-pressure hydrogen storage tank technology is mature, highly safe, and hydrogen refueling time is comparable to that of gasoline and diesel vehicles, generally requiring refueling to be carried out at hydrogen refueling stations.

[0092] In related technologies, when refueling an on-board hydrogen storage system, hydrogen is typically drawn from the hydrogen storage cylinders in order of low pressure to high pressure, and the cylinders are switched when the pressure of a particular cylinder falls below the pressure of the on-board hydrogen storage container. Simultaneously, the compressor replenishes hydrogen from the storage cylinders in order of high pressure to low pressure, and switches back to the storage cylinders when the pressure of a particular cylinder reaches its full load pressure. However, during the above hydrogen refueling and replenishment process, the pressure of the low-pressure hydrogen storage cylinders sometimes exceeds that of the high-pressure cylinders, resulting in insufficient utilization of the high-pressure hydrogen and thus reducing the refueling capacity.

[0093] To overcome the technical problems existing in the above-mentioned related technologies, this disclosure provides a control method, device, storage medium, and electronic equipment for a hydrogen refueling station. Using the above technical solution, the control device acquires hydrogen storage pressure information from multiple hydrogen storage cylinder groups via pressure sensors. Based on this multiple hydrogen storage pressure information, a gas extraction pressure threshold, and a gas replenishment pressure threshold, the control device determines the target hydrogen storage cylinder group and controls the compressor to replenish hydrogen to that target hydrogen storage cylinder group. In this way, by setting corresponding hydrogen storage pressure thresholds, corresponding gas extraction pressure thresholds, and gas replenishment pressure thresholds for each hydrogen storage cylinder group, it is possible to maintain each level of hydrogen storage cylinder group within a specific pressure level during hydrogen refueling. This enables multi-level refueling according to real-time pressure levels, increases the utilization rate of the hydrogen storage cylinder groups, avoids the problem of low-pressure hydrogen storage cylinder groups having higher pressures than high-pressure hydrogen storage cylinder groups, prevents the underutilization of high-pressure hydrogen, and effectively improves the refueling capacity of the hydrogen refueling station.

[0094] The following example, using a hydrogen refueling station as an example, further illustrates the relevant technologies: A hydrogen refueling station may include a hydrogen storage system, multiple hydrogen storage cylinder groups, a hydrogen dispenser, a pressure sensor, and control devices, among other main equipment. The hydrogen storage cylinder groups are divided into three levels: low-pressure, medium-pressure, and high-pressure. The compressor displacement is 1500 Nm3 / h, the inlet pressure is 5-20 MPa, the outlet pressure is 45 MPa, the total hydrogen capacity of the hydrogen storage cylinder groups is 250 kg, the ratio of the three hydrogen storage capacities is 2:2:1, the hydrogen source pressure is 20 MPa, and the hydrogen storage capacity is 360 kg.

[0095] The present disclosure will now be described in conjunction with specific embodiments.

[0096] Figure 1 This is a flowchart illustrating a control method for a hydrogen refueling station according to an exemplary embodiment of this disclosure. The method is applied to a control device. The hydrogen refueling station includes a compressor, multiple hydrogen storage cylinder groups, a pressure sensor, and a control device. The hydrogen storage cylinder groups are connected to the control device via the pressure sensor, and the compressor is connected to the hydrogen storage cylinder groups. Figure 1 As shown, the method includes steps S101 to S103.

[0097] In step S101, the hydrogen storage pressure information of multiple hydrogen storage cylinder groups is obtained through pressure sensors.

[0098] The hydrogen storage pressure information is used to characterize the specific hydrogen pressure value inside the corresponding hydrogen storage cylinder group. The pressure sensor is installed inside each hydrogen storage cylinder group to obtain the hydrogen storage pressure information of the hydrogen storage cylinder group.

[0099] In some embodiments, the hydrogen refueling station includes a compressor. If the hydrogen pressure inside the hydrogen storage cylinder group is insufficient, the compressor can be connected to the hydrogen storage cylinder group, and then the control device can obtain hydrogen storage pressure information of multiple hydrogen storage cylinder groups from the pressure sensor.

[0100] In step S102, the control device determines the target hydrogen storage cylinder group based on the multiple hydrogen storage pressure information, the gas extraction pressure threshold, and the gas replenishment pressure threshold.

[0101] The gas intake pressure threshold is used to characterize the minimum pressure threshold at which the hydrogen storage cylinder group can add hydrogen to the on-board hydrogen storage system when the on-board hydrogen storage system is connected to the multiple hydrogen storage cylinder groups through the hydrogen refueling machine. The gas replenishment pressure threshold is used to characterize the maximum pressure threshold at which the hydrogen storage cylinder group can receive replenished hydrogen when the hydrogen pressure inside the hydrogen storage cylinder group is insufficient and it is connected to the compressor.

[0102] In this embodiment, after obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding gas extraction pressure threshold and gas replenishment pressure threshold for each hydrogen storage cylinder group can be obtained from the database. The database can pre-store multiple preset gas extraction pressure thresholds and preset gas replenishment pressure thresholds corresponding to preset hydrogen storage cylinder groups. After obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding hydrogen storage cylinder group is searched from the multiple preset hydrogen storage cylinder groups, and the corresponding gas extraction pressure threshold and gas replenishment pressure threshold for each hydrogen storage cylinder group are obtained. Then, the target hydrogen storage cylinder group can be determined based on the multiple hydrogen storage pressure information, gas extraction pressure thresholds, and gas replenishment pressure thresholds.

[0103] In step S103, the compressor is controlled to replenish hydrogen to the target hydrogen storage cylinder group.

[0104] Using the above technical solution, the control device acquires hydrogen storage pressure information from multiple hydrogen storage cylinder groups via pressure sensors. Based on this information, the gas extraction pressure threshold, and the gas replenishment pressure threshold, the control device determines the target hydrogen storage cylinder group and controls the compressor to replenish hydrogen to that target group. By setting corresponding hydrogen storage pressure thresholds, gas extraction pressure thresholds, and gas replenishment pressure thresholds for each hydrogen storage cylinder group, the system can maintain each group at a specific pressure level during refueling. This allows for multi-stage refueling based on real-time pressure levels, increasing the utilization rate of the hydrogen storage cylinder groups and preventing situations where low-pressure cylinders have higher pressures than high-pressure cylinders. This prevents the underutilization of high-pressure hydrogen and effectively improves the refueling capacity of the hydrogen refueling station.

[0105] In some embodiments, such as Figure 2 As shown, step S102 above includes the following steps.

[0106] In step S1021, if it is determined that all of the multiple hydrogen storage pressure information are less than or equal to the gas extraction pressure threshold, hydrogen is replenished to the first target hydrogen storage cylinder group.

[0107] Among them, the first target hydrogen storage cylinder group is the hydrogen storage cylinder group with the largest hydrogen storage pressure among the multiple hydrogen storage pressure information that are all less than or equal to the gas extraction pressure threshold.

[0108] In this step, after obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, it can be determined, based on the gas extraction pressure threshold, whether there are one or more hydrogen storage cylinder groups whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold. In one possible implementation, if it is determined that there is a hydrogen storage cylinder group whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, this hydrogen storage cylinder group can be designated as the first target hydrogen storage cylinder group, and then a compressor can be used to replenish hydrogen to the first target hydrogen storage cylinder group. In another possible implementation, if it is determined that there are multiple hydrogen storage cylinder groups whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, the multiple hydrogen storage cylinder groups with pressure information less than or equal to the gas extraction pressure threshold can be arranged in a preset order. For example, the hydrogen storage pressure information corresponding to the multiple hydrogen storage cylinder groups with pressure information less than or equal to the gas extraction pressure threshold can be arranged in ascending order; then, the hydrogen storage cylinder group with the highest hydrogen storage pressure information can be designated as the first target hydrogen storage cylinder group, and a compressor can be used to replenish hydrogen to the first target hydrogen storage cylinder group.

[0109] In step S1022, if it is determined that the hydrogen storage pressure information after replenishing the first target hydrogen storage cylinder group is greater than the gas extraction pressure threshold, the replenishment of hydrogen to the first target hydrogen storage cylinder group is stopped.

[0110] In this step, the compressor continuously replenishes hydrogen to the first target hydrogen storage cylinder group. During the continuous replenishment process, the hydrogen storage pressure information of the first target hydrogen storage cylinder group can be acquired periodically. If it is determined that the hydrogen storage pressure information of the first target hydrogen storage cylinder group after replenishment is greater than the gas extraction pressure threshold, the compressor can be controlled by the controller to stop replenishing hydrogen to the first target hydrogen storage cylinder group.

[0111] Considering that if the hydrogen storage pressure of one hydrogen storage cylinder group is determined to be less than or equal to the gas extraction pressure threshold, the hydrogen replenishment operation can be stopped after replenishing the first target hydrogen storage cylinder group; if the hydrogen storage pressure of multiple hydrogen storage cylinder groups is determined to be less than or equal to the gas extraction pressure threshold, after replenishing the first target hydrogen storage cylinder group, a new first target hydrogen storage cylinder group is selected from the multiple hydrogen storage cylinder groups (excluding the first target hydrogen storage cylinder group) for hydrogen replenishment, until the hydrogen storage pressure of all hydrogen storage cylinder groups is greater than the gas extraction pressure threshold.

[0112] In some embodiments, such as Figure 3 As shown, step S102 above includes the following steps.

[0113] In step S1023, if it is determined that the hydrogen storage pressure information is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, hydrogen is replenished to the second target hydrogen storage cylinder group.

[0114] Among them, the second target hydrogen storage cylinder group is the hydrogen storage cylinder group with the largest hydrogen storage pressure information that is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold.

[0115] In this step, after obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, it can be determined whether there is one or more hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, based on the gas extraction pressure threshold. In one possible implementation, if it is determined that the hydrogen storage pressure of a hydrogen storage cylinder group is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, this hydrogen storage cylinder group can be designated as the second target hydrogen storage cylinder group, and then a compressor can be used to replenish hydrogen to the second target hydrogen storage cylinder group. In another possible implementation, if it is determined that the hydrogen storage pressure of multiple hydrogen storage cylinder groups is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, the multiple hydrogen storage cylinder groups with pressures greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold can be arranged in a preset order. For example, the hydrogen storage pressure information corresponding to the multiple hydrogen storage cylinder groups can be arranged in ascending order; then the hydrogen storage cylinder group with the highest hydrogen storage pressure information can be designated as the second target hydrogen storage cylinder group, and a compressor can be used to replenish hydrogen to the second target hydrogen storage cylinder group.

[0116] In step S1024, if it is determined that the hydrogen storage pressure information after the second target hydrogen storage cylinder group is replenished with hydrogen is greater than the replenishment pressure threshold, the replenishment of hydrogen to the second target hydrogen storage cylinder group is stopped.

[0117] In this step, the compressor continuously replenishes hydrogen to the second target hydrogen storage cylinder group. During the continuous replenishment process, the hydrogen storage pressure information of the second target hydrogen storage cylinder group can be acquired periodically. If it is determined that the hydrogen storage pressure information of the second target hydrogen storage cylinder group after replenishment is greater than the replenishment pressure threshold, the compressor can be controlled by the controller to stop replenishing hydrogen to the second target hydrogen storage cylinder group.

[0118] Considering that if the hydrogen storage pressure of one hydrogen storage cylinder group is determined to be greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, the hydrogen replenishment operation can be stopped after replenishing the second target hydrogen storage cylinder group. If the hydrogen storage pressure of multiple hydrogen storage cylinder groups is determined to be greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, after replenishing the second target hydrogen storage cylinder group, a new second target hydrogen storage cylinder group (excluding the second target hydrogen storage cylinder group) is selected for hydrogen replenishment until the hydrogen storage pressure of all hydrogen storage cylinder groups is greater than the gas replenishment pressure threshold. Furthermore, if a hydrogen storage cylinder group is found to have a pressure below the gas extraction pressure limit, the replenishment is switched to that hydrogen storage cylinder group until the pressure of that hydrogen storage cylinder group is higher than its gas extraction pressure limit.

[0119] In some embodiments, such as Figure 4 As shown, step S102 above includes the following steps.

[0120] In step S1025, if it is determined that the hydrogen storage pressure information is greater than the gas replenishment pressure threshold, hydrogen is replenished to the third target hydrogen storage cylinder group.

[0121] Among them, the third target hydrogen storage cylinder group is the hydrogen storage cylinder group with the largest hydrogen storage pressure information that is greater than the gas replenishment pressure threshold.

[0122] In step S1026, if it is determined that the hydrogen storage pressure information of the third target hydrogen storage cylinder group is full after hydrogen replenishment, hydrogen replenishment to the third target hydrogen storage cylinder group is stopped.

[0123] In some embodiments, such as Figure 5 As shown, the hydrogen refueling station also includes an on-board hydrogen storage system and a hydrogen refueling machine; the on-board hydrogen storage system is connected to the multiple hydrogen storage cylinder groups through the hydrogen refueling machine; the method also includes steps S104 and S105.

[0124] In step S104, the hydrogen refueling machine is controlled to refuel the on-board hydrogen storage system using the first hydrogen storage cylinder group.

[0125] The first hydrogen storage cylinder group is the hydrogen storage cylinder group among the plurality of hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold.

[0126] In some embodiments, after obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding gas extraction pressure threshold for each hydrogen storage cylinder group can be obtained from a database. This database may pre-store multiple preset gas extraction pressure thresholds corresponding to preset hydrogen storage cylinder groups. After obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding hydrogen storage cylinder group is searched from the multiple preset hydrogen storage cylinder groups, and the corresponding gas extraction pressure threshold for each hydrogen storage cylinder group is obtained. Then, from the multiple hydrogen storage cylinder groups, the hydrogen storage cylinder group whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold is determined, and this hydrogen storage cylinder group is designated as the first hydrogen storage cylinder group. The hydrogen refueling machine is then controlled to use the first hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0127] In step S105, if it is determined that the hydrogen storage pressure of the first hydrogen storage cylinder group is less than the corresponding gas supply pressure threshold, the hydrogen refueling machine is controlled to use the second hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0128] The second hydrogen storage cylinder group is the hydrogen storage cylinder group among the plurality of hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold.

[0129] In some embodiments, during the process of controlling the hydrogen refueling machine to refuel the on-board hydrogen storage system using the first hydrogen storage cylinder group, the hydrogen storage pressure information of the first hydrogen storage cylinder group and the hydrogen storage information of the on-board hydrogen storage system can be periodically acquired through a pressure sensor, and the gas supply pressure threshold of the first hydrogen storage cylinder group can be acquired. In one possible implementation, if the hydrogen storage pressure information of the first hydrogen storage cylinder group is lower than the corresponding gas supply pressure threshold, it is determined that the on-board hydrogen storage system is still not fully loaded based on the hydrogen storage information of the on-board hydrogen storage system. In this case, the hydrogen refueling machine can be controlled to refuel the on-board hydrogen storage system using the second hydrogen storage cylinder group. In another possible implementation, if the hydrogen storage pressure information of the first hydrogen storage cylinder group is greater than or equal to the corresponding gas supply pressure threshold, it is determined that the on-board hydrogen storage system is fully loaded based on the hydrogen storage information of the on-board hydrogen storage system. In this case, the hydrogen refueling machine is controlled to stop using the first hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0130] Using the above technical solution, the control device acquires hydrogen storage pressure information of multiple hydrogen storage cylinder groups through pressure sensors; controls the hydrogen refueling machine to use the first hydrogen storage cylinder group to refuel the on-board hydrogen storage system, the first hydrogen storage cylinder group being the hydrogen storage cylinder group whose hydrogen storage pressure information is greater than or equal to the corresponding gas intake pressure threshold; if it is determined that the hydrogen storage pressure information of the first hydrogen storage cylinder group is less than the corresponding gas supply pressure threshold, the control device controls the hydrogen refueling machine to use the second hydrogen storage cylinder group to refuel the on-board hydrogen storage system, the second hydrogen storage cylinder group being the hydrogen storage cylinder group whose hydrogen storage pressure information is greater than or equal to the corresponding gas intake pressure threshold. By setting corresponding gas intake pressure thresholds and corresponding gas supply pressure thresholds for each hydrogen storage cylinder group, it is possible to maintain each level of hydrogen storage cylinder group within a specific pressure range during hydrogen refueling. This enables multi-stage refueling based on real-time pressure levels, increases the utilization rate of the hydrogen storage cylinder groups, avoids the problem of low-pressure hydrogen storage cylinder groups having higher pressures than high-pressure hydrogen storage cylinder groups, prevents high-pressure hydrogen from being underutilized, and effectively improves the refueling capacity of hydrogen refueling stations.

[0131] In some embodiments, such as Figure 6 As shown, step S104 above includes the following steps.

[0132] In step S1041, the hydrogen storage cylinder group whose hydrogen storage pressure information is greater than or equal to the gas extraction pressure threshold is selected as the first candidate hydrogen storage cylinder group.

[0133] For example, after obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding gas extraction pressure threshold for each hydrogen storage cylinder group can be obtained from the database. Then, from the multiple hydrogen storage cylinder groups, the hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold can be determined, and the hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold are selected as the first candidate hydrogen storage cylinder groups. The database can pre-store multiple preset gas extraction pressure thresholds corresponding to preset hydrogen storage cylinder groups. After obtaining the hydrogen storage pressure information of multiple hydrogen storage cylinder groups, the corresponding hydrogen storage cylinder group can be searched from the multiple preset hydrogen storage cylinder groups, and the gas extraction pressure threshold for each hydrogen storage cylinder group can be obtained.

[0134] In step S1042, the hydrogen storage pressure information corresponding to the first candidate hydrogen storage cylinder group is arranged in a preset order to obtain the first hydrogen storage pressure information with the smallest hydrogen storage pressure information.

[0135] For example, considering that there may be multiple first candidate hydrogen storage cylinder groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold, the hydrogen storage pressure information corresponding to the multiple first candidate hydrogen storage cylinder groups can be arranged in a preset order. For example, the hydrogen storage pressure information corresponding to the multiple first candidate hydrogen storage cylinder groups can be arranged in ascending order; then the one with the smallest hydrogen storage pressure information can be taken as the first hydrogen storage pressure information.

[0136] In step S1043, the hydrogen storage cylinder group corresponding to the first hydrogen storage pressure information is designated as the first hydrogen storage cylinder group.

[0137] In step S1044, the hydrogen refueling machine is controlled to refuel the on-board hydrogen storage system using the first hydrogen storage cylinder group.

[0138] By adopting the above technical solution, we can avoid the situation in the prior art where the high-pressure hydrogen storage cylinder group is preferentially used, which leads to the pressure of the low-pressure hydrogen storage cylinder group being higher than that of the high-pressure hydrogen storage cylinder group. This results in the high-pressure hydrogen not being fully utilized, thus reducing the hydrogen refueling capacity. Instead, we can preferentially use the low-pressure hydrogen storage cylinder group that meets the corresponding gas extraction pressure threshold, thereby increasing the utilization rate of the hydrogen storage cylinder group.

[0139] In some embodiments, such as Figure 7 As shown, step S104 above also includes the following steps.

[0140] In step S1045, the hydrogen storage information of the on-board hydrogen storage system is obtained.

[0141] For example, in the process of controlling the hydrogen refueling machine to refuel the on-board hydrogen storage system using the first hydrogen storage cylinder group, it is necessary to periodically obtain the current hydrogen storage pressure information of the first hydrogen storage cylinder group, the hydrogen storage information of the on-board hydrogen storage system, and obtain the gas supply pressure threshold of the first hydrogen storage cylinder group.

[0142] In step S1046, if it is determined that the hydrogen storage information is greater than or equal to a preset storage threshold, the hydrogen refueling machine is controlled to stop using the first hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0143] For example, after obtaining the hydrogen storage information of the on-board hydrogen storage system, a preset storage threshold of the on-board hydrogen storage system can be determined from a preset database. The preset storage threshold is used to describe the maximum hydrogen storage capacity of the on-board hydrogen storage system. If the hydrogen storage information is determined to be greater than or equal to the preset storage threshold, the hydrogen refueling machine is controlled to stop using the first hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0144] By adopting the above technical solution, hydrogen refueling of the on-board hydrogen storage system can be stopped immediately after the system is fully loaded.

[0145] In some embodiments, such as Figure 8 As shown, step S105 above also includes the following steps.

[0146] In step S1051, if it is determined that the hydrogen storage information is less than a preset storage threshold, the second hydrogen storage cylinder group is determined from the plurality of hydrogen storage cylinder groups based on the hydrogen storage pressure information.

[0147] Optionally, the hydrogen storage cylinder group whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold can be first regarded as the second candidate hydrogen storage cylinder group, and the first candidate hydrogen storage cylinder group is not included in the second candidate hydrogen storage cylinder group; then, by arranging the hydrogen storage pressure information corresponding to the second candidate hydrogen storage cylinder group according to a preset arrangement order, the second hydrogen storage pressure information with the smallest hydrogen storage pressure information can be obtained; secondly, the hydrogen storage cylinder group corresponding to the second hydrogen storage pressure information can be regarded as the second hydrogen storage cylinder group.

[0148] In step S1052, the hydrogen refueling machine is controlled to use the second hydrogen storage cylinder group to refuel the on-board hydrogen storage system.

[0149] By adopting the above technical solution, after the on-board hydrogen storage system is refueled with hydrogen using the first hydrogen storage cylinder group, if the on-board hydrogen storage system is not fully loaded, a suitable hydrogen storage cylinder group can be selected from the remaining hydrogen storage cylinder groups to continue refueling the on-board hydrogen storage system.

This allows for multi-stage refueling based on real-time pressure levels, increasing the utilization rate of the hydrogen storage cylinder groups and preventing situations where low-pressure cylinders have higher pressures than high-pressure cylinders. This prevents the underutilization of high-pressure hydrogen and effectively improves the refueling capacity of the hydrogen refueling station.
