[0033] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application and should not be construed as a limitation to the present application.

[0034] The hydrogenation control method, computer-readable storage medium, hydrogenation control device and hydrogenation device proposed by the embodiments of the present application will be described below with reference to the accompanying drawings.

[0035] In the related art, it is stipulated in the hydrogen refueling protocol that in the initial refueling stage, a pulse signal will be sent first, and the total volume of the downstream hydrogen storage system will be estimated according to the pressure drop of the downstream. Subsequently, the average pressure rise rate during the refueling process is obtained by looking up a table based on the volume of the hydrogen storage system, the pre-cooling temperature of the fuel, the ambient temperature, and the initial pressure of the hydrogen storage system, and the refueling parameters are set. Among them, the average pressure rise rate determines the speed of the entire energy replenishment process. In this technical solution, the total volume of the on-vehicle hydrogen storage system is estimated through the pulse signal and its pressure drop, and the average pressure rise rate determined by looking up the table according to the hydrogen refueling protocol is the parameter setting based on the preset single-bottle group system. However, in actual vehicles, due to layout space limitations, a multi-bottle group parallel structure is usually adopted. For example, passenger cars use 2-4 gas cylinders, and commercial vehicles use 4-8 gas cylinders. The heat dissipation conditions of the multi-bottle group are better than those of the single-bottle group, and it is not easy to trigger the over-temperature, over-pressure, and overcharge boundaries. Using the average pressure rise rate set under the single-bottle group conditions is redundant and is not conducive to improving the refueling speed. In addition, the types of hydrogen storage cylinders are diverse, and the average pressure rise rate in the hydrogen refueling protocol also limits the improvement of the refueling speed and the matching degree.

[0036] To solve the above at least one technical problem, the present application proposes a hydrogenation control method. This method first obtains the initial average pressure rise rate of hydrogenation of the hydrogen storage system, and obtains the type of hydrogen storage cylinders of the hydrogen storage system and / or the volume of each hydrogen storage cylinder, and matches the correction coefficient of the initial average pressure rise rate according to the type of hydrogen storage cylinders and / or the volume of each hydrogen storage cylinder. Then, the initial average pressure rise rate is corrected according to the correction coefficient, and the hydrogenation parameters are determined using the corrected initial average pressure rise rate for hydrogenation control. Thus, this method corrects the initial average pressure rise rate according to the type of hydrogen storage cylinders and / or the volume of each hydrogen storage cylinder, and makes it match the hydrogen storage parameters of the hydrogen storage system on the premise of ensuring hydrogenation safety, and the hydrogen storage system can be hydrogenated at a better hydrogenation speed.

[0037] The hydrogenation control method can be applied to a hydrogen dispenser in a hydrogen refueling station, and the hydrogen storage system can be the hydrogen storage system in a vehicle. Then, when the gun of the hydrogen dispenser is connected to the hydrogen refueling port of the vehicle, the control method is triggered to be executed to hydrogenate the hydrogen storage system of the vehicle. The hydrogenation control method of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Figure 1 It is a flowchart of the hydrogenation control method according to an embodiment of the present application.

[0039] As Figure 1 shown, the hydrogenation control method of the embodiment of the present application includes:

[0040] S1, obtain the initial average pressure rise rate of hydrogenation of the hydrogen storage system, as well as the type of hydrogen storage cylinder of the hydrogen storage system and / or the volume of each hydrogen storage cylinder;

[0041] S2, match the correction coefficient of the initial average pressure rise rate according to the type of hydrogen storage cylinder and / or the volume of each hydrogen storage cylinder;

[0042] S3, correct the initial average pressure rise rate according to the correction coefficient, and perform hydrogenation control based on the corrected initial average pressure rise rate.

[0043] Specifically, when the hydrogen storage system includes one hydrogen storage cylinder, the correction coefficient of the initial average pressure rise rate can be determined according to the type of hydrogen storage cylinder, so as to correct the initial average pressure rise rate based on the correction coefficient and apply it to the filling control to match a better filling speed. The type of hydrogen storage cylinder is divided according to the material selected for the internal structure, including type I hydrogen storage cylinder (all-metal gas cylinder), type II hydrogen storage cylinder (metal inner liner circumferentially wound gas cylinder), type III hydrogen storage cylinder (metal inner liner fully wound gas cylinder), and type IV hydrogen storage cylinder (plastic inner liner fully wound gas cylinder). As Figure 3 shown, the blue line is for type IV cylinder (plastic inner liner), and the yellow line is for type III cylinder (metal inner liner). When filling type IV cylinder and type III cylinder with the same average pressure rise rate, the maximum temperature and real-time temperature of type III cylinder are significantly lower than those of type IV cylinder. Therefore, type III cylinder can use a larger average pressure rise rate to improve the energy replenishment speed. In addition, only type III hydrogen storage cylinder and type IV hydrogen storage cylinder are currently used in the field of on-vehicle hydrogen storage. When hydrogenating the hydrogen storage system of a vehicle, only these two types of gas cylinders can be identified and judged.

[0044] When the hydrogen storage system includes multiple hydrogen storage cylinders, as Figure 2As shown, the correction coefficient of the initial average pressure rise rate can be determined only according to the type of hydrogen storage cylinder, or only according to the volume of each hydrogen storage cylinder, or the correction coefficient of the initial average pressure rise rate can be jointly matched according to the type of hydrogen storage cylinder and the volume of each hydrogen storage cylinder, and then the initial average pressure rise rate is corrected based on the correction coefficient and applied to the filling control. As Figure 4 As shown, the blue line is a single 120L gas cylinder single-cylinder group, and the yellow line is a multi-cylinder group of 2 60L gas cylinders. When filling with the same average pressure rise rate, the highest temperature and the real-time temperature of the multi-cylinder group are significantly lower than those of the single-cylinder group. Therefore, the multi-cylinder group can use a larger average pressure rise rate to improve the energy replenishment speed.

[0045] Before filling the hydrogen storage system in this embodiment, first obtain the initial average pressure rise rate of hydrogen addition to the hydrogen storage system. The initial average pressure rise rate can be obtained by looking up a table according to the total volume of the hydrogen storage system, the fuel precooling temperature, the ambient temperature, and the initial pressure of the hydrogen storage system. Among them, the total volume of the hydrogen storage system can be obtained by testing, or after obtaining the volume of each hydrogen storage cylinder, the volumes of each hydrogen storage cylinder can be added up, and there is no specific limitation.

[0046] At the same time, obtain the type of hydrogen storage cylinder of the hydrogen storage system and / or the volume of each hydrogen storage cylinder based on the target correction requirement. For example, it can be obtained based on the information interaction between the hydrogen refueling station and the vehicle, or obtained by detection.

[0047] In the case of correcting the initial average pressure rise rate using the type of hydrogen storage cylinder for hydrogen addition control, the corresponding correction coefficient of the initial average pressure rise rate is obtained by looking up a table according to the obtained type of hydrogen storage cylinder or calculated based on a preset function. In the case of correcting the initial average pressure rise rate using the volume of each hydrogen storage cylinder for hydrogen addition control, the corresponding correction coefficient k1 of the initial average pressure rise rate is obtained by looking up a table according to the obtained volume of each hydrogen storage cylinder or calculated based on a preset function. In the case of correcting the initial average pressure rise rate k2 using the type of hydrogen storage cylinder and the volume of each hydrogen storage cylinder for hydrogen addition control, the corresponding correction coefficient k3 of the initial average pressure rise rate can be obtained by looking up a table according to the obtained type of hydrogen storage cylinder and the volume of each hydrogen storage cylinder or calculated based on a preset function. It can be understood that the correction coefficient k3 can be directly determined based on the type of hydrogen storage cylinder and the volume of each hydrogen storage cylinder, or can be calculated from the correction coefficient k1 determined according to the type of hydrogen storage cylinder k3 and the correction coefficient k2 determined according to the volume of each hydrogen storage cylinder.

[0048] Then, calculate the product of the correction coefficient and the initial average pressure rise rate to obtain the corrected initial average pressure rise rate. Set the filling parameters according to the corrected initial average pressure rise rate for the filling control of the hydrogen storage system. For example, in an embodiment where the initial average pressure rise rate APRR is corrected based on the type of hydrogen storage cylinder, the corrected initial average pressure rise rate APRR' = APRR * k1; in an embodiment where the initial average pressure rise rate APRR is corrected based on the volume of each hydrogen storage cylinder, the corrected initial average pressure rise rate APRR' = APRR * k2; in an embodiment where the initial average pressure rise rate APRR is corrected based on the type of hydrogen storage cylinder and the volume of each hydrogen storage cylinder, the corrected initial average pressure rise rate APRR' = APRR * k1 * k2, thereby ensuring filling safety when the filling speed is already sufficient or the external conditions are relatively harsh.

[0049] This embodiment can correct the initial average pressure rise rate based on the type of hydrogen storage cylinder of the energy storage system and / or the volume of each hydrogen storage cylinder to determine the average pressure rise rate matching the energy storage system, and use a better filling speed for its filling control. It can adopt a faster hydrogen filling speed on the premise of ensuring hydrogen filling safety.

[0050] In an embodiment of the present application, the hydrogen filling control method further includes: when the initial average pressure rise rate does not meet the preset conditions, matching the correction coefficient of the initial average pressure rise rate according to the type of hydrogen storage cylinder and / or the volume of each hydrogen storage cylinder.

[0051] Specifically, the preset conditions can be set according to the actual situation. For example, determine the preset average pressure rise rate range, preset limit, etc. according to the vehicle type. Assume that the preset condition is that the initial average pressure rise rate is within the preset average pressure rise rate range. Then, when the initial average rise rate does not meet the preset conditions, for example, when the determined initial average pressure rise rate is less than the preset average pressure rise rate range, it is considered that the initial average pressure rise rate is low and the optimal filling speed cannot be achieved. At this time, the initial average pressure rise rate is adjusted and corrected upward based on the type of hydrogen storage cylinder and / or the volume of each hydrogen storage cylinder; when the initial average pressure rise rate is greater than the preset pressure rise rate range, it is considered that the initial average pressure rise rate is high, which may cause overheating and abnormal vehicle conditions. At this time, the initial average pressure rise rate is adjusted and corrected downward according to the type of hydrogen storage cylinder and / or the volume of each hydrogen storage cylinder. When the initial average rise rate meets the preset conditions, that is, when the initial average pressure rise rate is within the preset pressure rise rate range, it is considered that the initial average pressure rise rate is close to or equal to the optimal average pressure rise rate. At this time, the hydrogen filling control is directly performed with this initial average pressure rise rate to reduce the calculation process.

[0052] In an embodiment of the present application, obtaining the type of hydrogen storage cylinder of a hydrogen storage system includes: performing a pre-hydrogenation operation of a target volume on any one hydrogen storage cylinder in the hydrogen storage system, and obtaining the temperature drop of the corresponding hydrogen storage tank within a preset time after the pre-hydrogenation operation ends; determining the type of hydrogen storage cylinder according to the temperature drop and a first preset relationship, where the first preset relationship is used to represent the mapping relationship between the temperature drop and the type of hydrogen storage cylinder.

[0053] Specifically, the types of hydrogen storage cylinders in each hydrogen storage system are the same, and the type of one of the hydrogen storage cylinders can be evaluated. Since different materials have different thermal resistances, for example, a plastic bottle liner has a very large thermal resistance, and the temperature drop when hydrogen is filled in will be very slow; if it is an aluminum inner liner, the temperature drop will be very fast. Therefore, this embodiment determines the type of hydrogen storage cylinder based on the temperature drop.

[0054] Take Figure 2 the shown hydrogen storage system as an example. This hydrogen storage system includes hydrogen storage cylinder 1 and hydrogen storage cylinder 2. Each hydrogen storage cylinder is respectively provided with a cut-off valve connected to the system pipeline. When the cut-off valve is in the closed state, the connection between the corresponding hydrogen storage cylinder and the system pipeline is cut off, and when the cut-off valve is in the open state, the connection between the corresponding hydrogen storage cylinder and the system pipeline is conducted. First, control the cut-off valve of hydrogen storage cylinder 1 to open, close the cut-off valve of hydrogen storage cylinder 2, and the hydrogen filling machine fills a target volume of hydrogen into hydrogen storage cylinder 1 through the system pipeline, that is, performs a pre-hydrogenation operation on hydrogen storage cylinder 1. Then, monitor the temperature of hydrogen storage cylinder 1 and calculate the temperature drop of hydrogen storage cylinder 1 within a preset time. Assume that the first preset relationship is a mapping table of hydrogen storage cylinder type - temperature drop range, then the corresponding hydrogen storage cylinder type can be obtained by looking up the table according to the obtained temperature drop of hydrogen storage cylinder 1.

[0055] In an embodiment of the present application, obtaining the volume of each hydrogen storage cylinder of a hydrogen storage system includes: performing a pre-hydrogenation operation of a target volume on each hydrogen storage cylinder respectively, and obtaining the pressure drop of the corresponding hydrogen storage tank within a preset time after each pre-hydrogenation operation ends; determining the volume of each hydrogen storage cylinder according to the pressure drop and a second preset relationship, where the second preset relationship is used to represent the mapping relationship between the pressure drop and the volume.

[0056] Specifically, the volume of each hydrogen storage cylinder is related to the pressure drop within the preset time obtained by testing, and can be obtained according to an empirical formula or by looking up a table. The second preset relationship can be a mapping table or a calculation formula between the pressure drop and the volume, and there is no specific limitation.

[0057] Continue to take Figure 2For example, assume that the second preset relationship is a mapping table between pressure drop and volume. The hydrogen storage bottles 1 and 2 are respectively provided with stop valves connected to the system pipeline. When the stop valve is in the closed state, the connection between the corresponding hydrogen storage bottle and the system pipeline is cut off. When the stop valve is in the open state, the connection between the corresponding hydrogen storage bottle and the system pipeline is conducted. First, control the stop valve of hydrogen storage bottle 1 to open and the stop valve of hydrogen storage bottle 2 to close, and fill hydrogen with a large flow rate into hydrogen storage bottle 1 with a target volume, that is, perform pre-hydrogenation operation on hydrogen storage bottle 1, and monitor the pressure of hydrogen storage bottle 1 to obtain the pressure drop of hydrogen storage bottle 1 within a preset time after the hydrogenation ends. Then, obtain the volume of hydrogen storage bottle 1 by looking up the table according to the pressure drop of hydrogen storage bottle 1. Then, control the stop valve of hydrogen storage bottle 1 to close and the stop valve of hydrogen storage bottle 2 to open, and fill hydrogen with a large flow rate into hydrogen storage bottle 2 with a target volume, that is, perform pre-hydrogenation operation on hydrogen storage bottle 2, and monitor the pressure of hydrogen storage bottle 2 to obtain the pressure drop of hydrogen storage bottle 2 within a preset time after the hydrogenation ends. Then, obtain the volume of hydrogen storage bottle 2 by looking up the table according to the pressure drop of hydrogen storage bottle 2.

[0058] In the above embodiment, by controlling the opening / closing of the stop valve of each hydrogen storage bottle, the pre-filling operation of the specified hydrogen storage bottle is realized to obtain the type of hydrogen storage bottle and / or the volume of each hydrogen storage bottle, so as to correct the initial average pressure rise rate. Then, the formal hydrogenation operation of the hydrogen storage system is performed with the corrected initial average pressure rise rate. During the formal hydrogenation process, the stop valves of all gas cylinders need to be opened to ensure that all gas cylinders in the hydrogen storage system are filled.

[0059] Furthermore, in the case where there is a two-way communication function between the hydrogen refueling station and the vehicle, after individually confirming the volume and / or type of each hydrogen storage bottle, it can be compared with the volume and / or type of each hydrogen storage bottle obtained based on communication. If there is a large deviation between the two sets of data, for example, the deviation amount between the volumes of each hydrogen storage bottle is greater than the preset volume or the types of hydrogen storage bottles are different, then there may be a detection failure at the hydrogen refueling station, or the data parameters in the vehicle have not been updated in time. At this time, the filling process is paused and waiting for further confirmation.

[0060] In an embodiment of the present application, the hydrogen storage system further includes at least one temperature sensor, and the temperature sensors correspond to the hydrogen storage bottles one by one. The temperature sensor is used to obtain the temperature of the corresponding hydrogen storage bottle and generate a temperature signal. Before performing the pre-hydrogenation operation with a target volume on each hydrogen storage bottle respectively, the hydrogenation control method further includes: receiving the temperature signals generated by at least one temperature sensor; determining the number of hydrogen storage bottles in the hydrogen storage system according to the number of temperature signals; determining the number of pre-hydrogenation operations according to the number of hydrogen storage bottles, so as to perform the pre-hydrogenation operation with a target volume on each hydrogen storage bottle respectively based on the number of pre-hydrogenation operations.

[0061] Specifically, to ensure application security, a temperature sensor is provided in the bottle valve of each hydrogen storage bottle in the hydrogen storage system. Thus, in this embodiment, the number of hydrogen storage bottles is determined according to the existing structure of the hydrogen storage system.

[0062] The number of temperature signals refers to the number of sources of temperature signals. The number of temperature signals obtained is the number of hydrogen storage bottles in the hydrogen storage system. Furthermore, the execution of the pre-hydrogenation operation is controlled according to the number of hydrogen storage bottles to ensure the volume evaluation of each hydrogen storage bottle and avoid waste of the pre-hydrogenation operation. For Figure 2 example, the temperature sensor in the bottle valve of hydrogen storage bottle 1 feeds back temperature signal 1, and the temperature sensor in the bottle valve of hydrogen storage bottle 2 feeds back temperature signal 2. When temperature signals 1 and 2 from two different IDs are received, it is determined that the number of temperature signals in this hydrogen storage system is 2, and two pre-hydrogenation operations need to be performed to separately perform volume detection on hydrogen storage 1 and hydrogen storage bottle 2 based on the measured pre-hydrogenation operation.

[0063] In an embodiment of the present application, a correction coefficient for matching the initial average pressure rise rate according to the type of hydrogen storage bottle includes: determining a first correction coefficient according to the type of hydrogen storage bottle and a third preset relationship, and using the first correction coefficient as the correction coefficient for the initial average pressure rise rate, where the third preset relationship is used to represent the mapping relationship between the type of hydrogen storage bottle and the first correction coefficient.

[0064] Specifically, the third preset relationship can be obtained through experiments by obtaining the average pressure rise rate corresponding to the preset temperature upper limit value for the type of hydrogen storage bottle, fitting the proportional relationship between it and the initial average pressure rise rate to obtain the corresponding fitting function formula, or directly presenting it in the form of a table.

[0065] In the embodiment where only the type of hydrogen storage bottle is used to correct the initial average pressure rise rate, a first correction coefficient k1 is obtained according to the type of hydrogen storage bottle and the third preset relationship, and the corrected initial average pressure rise rate = initial average pressure rise rate * k1.

[0066] In an embodiment of the present application, a correction coefficient for matching the initial average pressure rise rate according to the volume of each hydrogen storage bottle includes: obtaining the maximum volume value among the volumes of each hydrogen storage bottle; determining a second correction coefficient according to the maximum volume value and a fourth preset relationship, and using the second correction coefficient as the correction coefficient for the initial average pressure rise rate, where the fourth preset relationship is used to represent the mapping relationship between the maximum volume value and the second correction coefficient.

[0067] Specifically, the fourth preset relationship can be obtained through experiments by obtaining the average pressure rise rate corresponding to the preset temperature upper limit value for the volume, fitting the proportional relationship between it and the initial average pressure rise rate to obtain the corresponding fitting function formula, or directly presenting it in the form of a table.
