Technical Field

[0001] The present disclosure relates to the technical field of hydrogen storage, and in particular to a control method, device, storage medium and electronic equipment for a hydrogen refueling station. Background Art

[0002] At present, the technology of on-board hydrogen high-pressure gas storage tanks has matured and is highly safe. The hydrogen fuel refueling time is comparable to that of gasoline and diesel vehicles, and generally needs to be carried out at a hydrogen refueling station.

[0003] In general, when filling the on-board hydrogen storage system with hydrogen, the hydrogen storage bottle groups are usually taken out in order from low pressure to high pressure, and the hydrogen storage bottle groups are switched when the hydrogen pressure of a certain bottle group is lower than the pressure of the on-board hydrogen storage container; at the same time, the compressor replenishes the hydrogen storage bottle groups in order from high pressure to low pressure, and the hydrogen storage bottle groups are switched when the hydrogen pressure of a certain hydrogen storage bottle group reaches the full load pressure. However, during the above-mentioned hydrogenation and gas replenishment operations, the pressure of the low-pressure hydrogen storage bottle group is sometimes higher than that of the high-pressure hydrogen storage bottle group, so that the high-pressure hydrogen cannot be fully utilized, thereby reducing the hydrogenation capacity.

[0090] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0091] Before introducing the specific implementation methods of the present disclosure in detail, the application scenarios of the present disclosure are first described. The present disclosure can be applied to the hydrogenation control scenario of a hydrogenation station. At present, the technology of on-board hydrogen high-pressure gas storage tanks is mature and safe. The hydrogen fuel filling time is comparable to that of gasoline and diesel vehicles, and generally needs to be carried out in a hydrogenation station.

[0092] In the related art, when hydrogen is refilled into the on-board hydrogen storage system, gas is usually taken from the hydrogen storage bottle group in the order from low pressure to high pressure, and the hydrogen storage bottle group is switched when the hydrogen pressure of a certain bottle group is lower than the pressure of the on-board hydrogen storage container; at the same time, the compressor replenishes gas from the hydrogen storage bottle group in the order from high pressure to low pressure, and the hydrogen storage bottle group is switched when the hydrogen pressure of a certain hydrogen storage bottle group reaches the full load pressure. However, during the above-mentioned hydrogenation and gas replenishment operations, the pressure of the low-pressure hydrogen storage bottle group is sometimes higher than that of the high-pressure hydrogen storage bottle group, so that the high-pressure hydrogen cannot be fully utilized, thereby reducing the hydrogenation capacity.

[0093] In order to overcome the technical problems existing in the above-mentioned related technologies, the present disclosure provides a control method, device, storage medium and electronic equipment for a hydrogen refueling station. By adopting the above-mentioned technical scheme, the control device obtains the hydrogen storage pressure information of multiple hydrogen storage bottle groups through a pressure sensor; the control device determines the target hydrogen storage bottle group according to the multiple hydrogen storage pressure information, the gas extraction pressure threshold, and the gas replenishment pressure threshold; and controls the compressor to replenish hydrogen to the target hydrogen storage bottle group. In this way, by setting the corresponding hydrogen storage pressure threshold, the corresponding gas extraction pressure threshold, and the gas replenishment pressure threshold for each hydrogen storage bottle group, it is possible to keep each level of hydrogen storage bottle group in a specific pressure level during the hydrogen refueling process, and realize multi-level refueling according to the real-time pressure level, which can increase the utilization rate of the hydrogen storage bottle group, avoid the problem that the pressure of the low-pressure hydrogen storage bottle group is higher than the pressure of the high-pressure hydrogen storage bottle group, and prevent the high-pressure hydrogen from not being fully utilized, thereby effectively improving the refueling capacity of the hydrogen refueling station.

[0094] Taking hydrogen refueling stations as an example, the current relevant technologies are further illustrated: hydrogen refueling stations can include main equipment such as hydrogen storage systems, multiple hydrogen storage bottle groups, hydrogen refueling machines, pressure sensors, and control devices. Among them, the hydrogen storage bottle groups are divided into three-stage bottle groups of low pressure, medium pressure and high pressure. The compressor displacement is 1500Nm3 / h, the inlet pressure is 5-20MPa, the outlet pressure is 45MPa, the total hydrogen capacity of the hydrogen storage bottle group is 250kg, the ratio of the three groups of hydrogen storage capacity is 2:2:1, the hydrogen source pressure is 20MPa, and the hydrogen storage capacity is 360kg.

[0095] The present disclosure is described below in conjunction with specific embodiments.

[0096] Figure 1 is a flow chart of a control method of a hydrogen refueling station provided by an exemplary embodiment of the present disclosure, the method is applied to a control device, the hydrogen refueling station includes a compressor, a plurality of hydrogen storage bottle groups, a pressure sensor, and a control device; the hydrogen storage bottle group is connected to the control device through the pressure sensor, and the compressor is connected to the hydrogen storage bottle group; Figure 1 As shown, the method includes steps S101 to S103.

[0097] In step S101, hydrogen storage pressure information of a plurality of hydrogen storage bottle groups is obtained through a pressure sensor.

[0098] Among them, the hydrogen storage pressure information is used to characterize the specific hydrogen pressure value inside the corresponding hydrogen storage bottle group, and the pressure sensor is arranged inside each hydrogen storage bottle group to obtain the hydrogen storage pressure information of the hydrogen storage bottle group.

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

[0100] In step S102, the control device determines a target hydrogen storage bottle group according to the multiple hydrogen storage pressure information, the gas extraction pressure threshold, and the gas replenishment pressure threshold.

[0101] Among them, the gas extraction pressure threshold is used to characterize the minimum pressure threshold for the hydrogen storage bottle group to add hydrogen to the on-board hydrogen storage system when the on-board hydrogen storage system is connected to the multiple hydrogen storage bottle groups through the hydrogen filling machine, and the gas replenishment pressure threshold is used to characterize the maximum pressure threshold for the hydrogen storage bottle group to be connected to the compressor and able to receive supplementary hydrogen when the hydrogen pressure inside the hydrogen storage bottle group is insufficient.

[0102] In this embodiment, after obtaining the hydrogen storage pressure information of multiple hydrogen storage bottle groups, the gas extraction pressure threshold and the gas replenishment pressure threshold corresponding to each hydrogen storage bottle group can be obtained from the database, wherein the database can pre-store preset gas extraction pressure thresholds and preset gas replenishment pressure thresholds corresponding to multiple preset hydrogen storage bottle groups, and then after obtaining the hydrogen storage pressure information of multiple hydrogen storage bottle groups, the corresponding hydrogen storage bottle group is searched from the multiple preset hydrogen storage bottle groups, and the gas extraction pressure threshold and the gas replenishment pressure threshold corresponding to each hydrogen storage bottle group are obtained; then the target hydrogen storage bottle 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 refill the target hydrogen storage bottle group with hydrogen.

[0104] By adopting the above technical solution, the control device obtains the hydrogen storage pressure information of multiple hydrogen storage bottle groups through the pressure sensor; the control device determines the target hydrogen storage bottle group according to the multiple hydrogen storage pressure information, the gas extraction pressure threshold, and the gas replenishment pressure threshold; and controls the compressor to replenish hydrogen to the target hydrogen storage bottle group. In this way, by setting the corresponding hydrogen storage pressure threshold, the corresponding gas extraction pressure threshold, and the gas replenishment pressure threshold for each hydrogen storage bottle group, it is possible to keep each level of hydrogen storage bottle group in a specific pressure level during the hydrogen refueling process, and to achieve multi-level refueling according to the real-time pressure level, which can increase the utilization rate of the hydrogen storage bottle group, avoid the problem that the pressure of the low-pressure hydrogen storage bottle group is higher than the pressure of the high-pressure hydrogen storage bottle group, and prevent the high-pressure hydrogen from not being fully utilized, thereby effectively improving the refueling capacity of the hydrogen refueling station.

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

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

[0107] Among them, the first target hydrogen storage bottle group is the largest hydrogen storage bottle group 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 bottle groups, it can be determined according to the gas extraction pressure threshold whether there is one or more hydrogen storage bottle groups in the hydrogen storage pressure information of the multiple hydrogen storage bottle groups whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold. In one possible implementation, when it is determined that there is a hydrogen storage bottle group whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, the hydrogen storage bottle group can be used as the first target hydrogen storage bottle group, and then the first target hydrogen storage bottle group can be replenished with hydrogen by a compressor; in another possible implementation, when it is determined that there are multiple hydrogen storage bottle groups whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, multiple hydrogen storage bottle groups less than or equal to the gas extraction pressure threshold can be arranged in a preset arrangement order, for example, the hydrogen storage pressure information corresponding to multiple hydrogen storage bottle groups less than or equal to the gas extraction pressure threshold can be arranged in order from small to large; then the hydrogen storage bottle group with the largest hydrogen storage pressure information can be used as the first target hydrogen storage bottle group, and the first target hydrogen storage bottle group can be replenished with hydrogen by a compressor.

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

[0110] In this step, the first target hydrogen storage bottle group is continuously replenished with hydrogen through the compressor. During the continuous hydrogen replenishment, the hydrogen storage pressure information of the first target hydrogen storage bottle group can be periodically obtained. When it is determined that the hydrogen storage pressure information of the first target hydrogen storage bottle group after hydrogen 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 bottle group.

[0111] Consider that, when it is determined that there is a hydrogen storage bottle group whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, the hydrogen replenishing action can be stopped after the first target hydrogen storage bottle group is replenished with hydrogen; if it is determined that there are multiple hydrogen storage bottle groups whose hydrogen storage pressure information is less than or equal to the gas extraction pressure threshold, after the first target hydrogen storage bottle group is replenished with hydrogen, a new first target hydrogen storage bottle group is determined from the multiple hydrogen storage bottle groups (except the first target hydrogen storage bottle group) for hydrogen replenishment until the hydrogen storage pressure information of all hydrogen storage bottle groups is greater than the gas extraction pressure threshold.

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

[0113] In step S1023, when 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, the second target hydrogen storage bottle group is replenished with hydrogen.

[0114] Among them, the second target hydrogen storage bottle group is the hydrogen storage bottle 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 bottle groups, it can be determined based on the gas extraction pressure threshold whether the hydrogen storage pressure information of one or more hydrogen storage bottle groups in the hydrogen storage pressure information of the multiple hydrogen storage bottle groups is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold. In one possible implementation, when it is determined that there is a hydrogen storage bottle group whose hydrogen storage pressure information is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, the hydrogen storage bottle group can be used as the second target hydrogen storage bottle group, and then a compressor can be used to replenish hydrogen to the second target hydrogen storage bottle group; in another possible implementation, when it is determined that there are multiple hydrogen storage bottle 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, multiple hydrogen storage bottle groups greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold can be arranged in a preset arrangement order, for example, the hydrogen storage pressure information corresponding to the multiple hydrogen storage bottle groups can be arranged in order from small to large; then the hydrogen storage bottle group with the largest hydrogen storage pressure information can be used as the second target hydrogen storage bottle group, and a compressor can be used to replenish hydrogen to the second target hydrogen storage bottle group.

[0116] In step S1024, when it is determined that the hydrogen storage pressure information of the second target hydrogen storage bottle group after hydrogen replenishment is greater than the hydrogen replenishment pressure threshold, hydrogen replenishment of the second target hydrogen storage bottle group is stopped.

[0117] In this step, the second target hydrogen storage bottle group is continuously replenished with hydrogen through the compressor. During the continuous hydrogen replenishment, the hydrogen storage pressure information of the second target hydrogen storage bottle group can be periodically obtained. When it is determined that the hydrogen storage pressure information of the second target hydrogen storage bottle group after hydrogen replenishment is greater than the gas replenishment pressure threshold, the compressor can be controlled by the controller to stop replenishing hydrogen to the second target hydrogen storage bottle group.

[0118] Considering that, when it is determined that there is a hydrogen storage bottle group whose hydrogen storage pressure information is greater than the gas extraction pressure threshold and less than or equal to the gas replenishment pressure threshold, the hydrogen replenishment action can be stopped after the second target hydrogen storage bottle group is replenished with hydrogen; if it is determined that there are multiple hydrogen storage bottle 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, after the second target hydrogen storage bottle group is replenished with hydrogen, a new second target hydrogen storage bottle group is determined from multiple hydrogen storage bottle groups (except the second target hydrogen storage bottle group) for hydrogen replenishment until the hydrogen storage pressure information of all hydrogen storage bottle groups is greater than the gas replenishment pressure threshold. And, if a hydrogen storage bottle group below the gas extraction pressure limit appears, switch to a hydrogen storage bottle group below the gas extraction pressure limit for gas replenishment until the pressure of the hydrogen storage bottle group is higher than the gas extraction pressure limit of the hydrogen storage bottle group.

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

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

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

[0122] In step S1026, when it is determined that the hydrogen storage pressure information of the third target hydrogen storage bottle group after hydrogen replenishment is fully loaded, hydrogen replenishment of the third target hydrogen storage bottle group is stopped.

[0123] In some embodiments, Figure 5 As shown, the hydrogen refueling station also includes a vehicle-mounted hydrogen storage system and a hydrogen refueling machine; the vehicle-mounted hydrogen storage system is connected to the multiple hydrogen storage bottle groups through the hydrogen refueling machine; the method also includes step S104 and step S105.

[0124] In step S104, the hydrogen filling machine is controlled to use the first hydrogen storage bottle group to fill the vehicle-mounted hydrogen storage system with hydrogen.

[0125] Among them, the first hydrogen storage bottle group is a hydrogen storage bottle group among the multiple hydrogen storage bottle 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 bottle groups, the gas extraction pressure threshold corresponding to each hydrogen storage bottle group can be obtained from the database, wherein the database can pre-store preset gas extraction pressure thresholds corresponding to multiple preset hydrogen storage bottle groups, and then after obtaining the hydrogen storage pressure information of multiple hydrogen storage bottle groups, the corresponding hydrogen storage bottle group is searched from the multiple preset hydrogen storage bottle groups, and the gas extraction pressure threshold corresponding to each hydrogen storage bottle group is obtained; then, from the multiple hydrogen storage bottle groups, the hydrogen storage bottle 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 bottle group whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold can be used as the first hydrogen storage bottle group, and the hydrogen filling machine is controlled to use the first hydrogen storage bottle group to hydrogenate the on-board hydrogen storage system.

[0127] In step S105, when it is determined that the hydrogen storage pressure information of the first hydrogen storage bottle group is less than the corresponding gas supply pressure threshold, the hydrogen filling machine is controlled to use the second hydrogen storage bottle group to fill the vehicle-mounted hydrogen storage system with hydrogen.

[0128] Among them, the second hydrogen storage bottle group is a hydrogen storage bottle group among the multiple hydrogen storage bottle groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold.

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

[0130] By adopting the above technical scheme, the control device obtains the hydrogen storage pressure information of multiple hydrogen storage bottle groups through the pressure sensor; controls the hydrogen filling machine to use the first hydrogen storage bottle group to hydrogenate the on-board hydrogen storage system, and the first hydrogen storage bottle group is the hydrogen storage bottle group among the multiple hydrogen storage bottle groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold; when it is determined that the hydrogen storage pressure information of the first hydrogen storage bottle group is less than the corresponding gas supply pressure threshold, controls the hydrogen filling machine to use the second hydrogen storage bottle group to hydrogenate the on-board hydrogen storage system, and the second hydrogen storage bottle group is the hydrogen storage bottle group among the multiple hydrogen storage bottle groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold. In this way, by setting the corresponding gas extraction pressure threshold and the corresponding gas supply pressure threshold for each hydrogen storage bottle group, the hydrogen storage bottle groups at each level can be kept within a specific pressure level during the hydrogen refueling process, and multi-stage refueling can be achieved according to the real-time pressure level. The utilization rate of the hydrogen storage bottle group can be increased, and the problem of the pressure of the low-pressure hydrogen storage bottle group being higher than the pressure of the high-pressure hydrogen storage bottle group can be avoided, preventing the high-pressure hydrogen from not being fully utilized, thereby effectively improving the refueling capacity of the hydrogen refueling station.

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

[0132] In step S1041, the hydrogen storage bottle 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 bottle group.

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

[0134] In step S1042, the hydrogen storage pressure information corresponding to the first candidate hydrogen storage bottle group is arranged according to a preset arrangement order to obtain the first hydrogen storage pressure information with the minimum hydrogen storage pressure information.

[0135] For example, considering that there may be multiple first candidate hydrogen storage bottle groups whose hydrogen storage pressure information is greater than or equal to the corresponding gas extraction pressure threshold, in this case, the hydrogen storage pressure information corresponding to the multiple first candidate hydrogen storage bottle groups can be arranged in a preset order. For example, the hydrogen storage pressure information corresponding to the multiple first candidate hydrogen storage bottle groups can be arranged in order from small to large; then the hydrogen storage pressure information with the smallest hydrogen storage pressure information can be used as the first hydrogen storage pressure information.

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

[0137] In step S1044, the hydrogen filling machine is controlled to use the first hydrogen storage bottle group to fill the vehicle-mounted hydrogen storage system with hydrogen.

[0138] By adopting the above technical scheme, it is possible to avoid the situation in the prior art where high-pressure hydrogen storage bottle groups are given priority, resulting in the pressure of the low-pressure hydrogen storage bottle groups being higher than the pressure of the high-pressure hydrogen storage bottle groups, so that the high-pressure hydrogen cannot be fully utilized, thereby reducing the hydrogen refueling capacity. Instead, low-pressure hydrogen storage bottle groups among the hydrogen storage bottle groups that meet the corresponding gas extraction pressure threshold are given priority, thereby increasing the utilization rate of the hydrogen storage bottle groups.

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

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

[0141] For example, in the process of controlling the hydrogen filling machine to use the first hydrogen storage bottle group to fill the on-board hydrogen storage system with hydrogen, it is necessary to periodically obtain the current hydrogen storage pressure information of the first hydrogen storage bottle group and the hydrogen storage information of the on-board hydrogen storage system, and obtain the gas supply pressure threshold of the first hydrogen storage bottle group.

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

[0143] For example, after obtaining the hydrogen storage information of the vehicle-mounted hydrogen storage system, a preset storage threshold of the vehicle-mounted hydrogen storage system can be determined from a preset database, and the preset storage threshold is used to describe the maximum threshold of the hydrogen that can be stored in the vehicle-mounted hydrogen storage system, and when it is determined that the hydrogen storage information is greater than or equal to the preset storage threshold, the hydrogen filling machine is controlled to stop using the first hydrogen storage bottle group to fill the vehicle-mounted hydrogen storage system with hydrogen.

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

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

[0146] In step S1051, when it is determined that the hydrogen storage information is less than a preset storage threshold, the second hydrogen storage bottle group is determined from the plurality of hydrogen storage bottle groups according to the hydrogen storage pressure information.

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

[0148] In step S1052, the hydrogen filling machine is controlled to use the second hydrogen storage bottle group to fill the vehicle-mounted hydrogen storage system with hydrogen.

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