[0002] Hydrogen refueling stations are important facilities that provide hydrogen refueling services for hydrogen fuel cell vehicles. Based on refueling time, they are divided into fast refueling and slow refueling. The former is based on the pressure difference between the hydrogen storage tank of the hydrogen refueling station and the hydrogen storage cylinder of the hydrogen fuel cell vehicle. The hydrogen storage tank of the hydrogen refueling station is filled with hydrogen using a hydrogen compressor, while the latter is filled with hydrogen fuel cell vehicles using a hydrogen compressor.
[0003] Currently, hydrogen refueling stations typically use fixed costs to calculate their hydrogen costs. However, electricity prices vary at different times, resulting in varying costs for the hydrogen compressor to refuel the station's storage tanks.

[0057] Figure 1 A flowchart illustrating a method for determining the hydrogen cost of a hydrogen refueling station according to an embodiment of this application is shown. See [link / reference]. Figure 1 This paper provides a method for determining the hydrogen cost of a hydrogen refueling station, which includes at least S1 to S4, detailed below:
[0058] In step S1, the pressure range from zero to maximum pressure of the hydrogen storage tank is divided into multiple unit pressure intervals. The maximum pressure of the hydrogen storage tank can be the maximum operating pressure of the hydrogen storage tank. For example, if the design pressure of the hydrogen storage tank is 49.5 MPa and the maximum operating pressure is 45 MPa, then the maximum pressure of the hydrogen storage tank is 45 MPa. The pressure range from zero to maximum pressure is divided into multiple unit pressure intervals, that is, the pressure range of 0-45 MPa is divided into multiple unit pressure intervals. If it is divided into 45 unit pressure intervals, then the first unit pressure interval is 0-1 MPa and the last unit pressure interval is 44-45 MPa.
[0059] In step S2, at the first time interval, the first hydrogen mass and the first hydrogen cost corresponding to the unit pressure range are determined.
[0060] In step S3, the fixed cost of hydrogen, the parameters of the hydrogen compressor within the target time period, and the time difference are obtained. The target time period is the time period from the first time to the second time, and the time difference is the difference between the second time and the first time, wherein the second time is after the first time.
[0061] In step S4, the second hydrogen cost corresponding to the unit pressure range at the second time is determined based on the first hydrogen mass, the first hydrogen cost, the hydrogen compressor parameters, the time difference, and the fixed hydrogen cost.
[0062] In some embodiments, the hydrogen compressor parameters include compressor power, compressor capacity, and compressor electricity cost. The compressor electricity cost is the electricity fee payable by the hydrogen refueling station when operating the compressor. Determining the second hydrogen cost corresponding to the unit pressure range at the second time based on the first hydrogen mass, the first hydrogen cost, the hydrogen compressor parameters, the time difference, and the hydrogen fixed cost includes: determining the first target cost corresponding to the unit pressure range at the first time based on the product of the first hydrogen mass and the first hydrogen cost; determining the second hydrogen mass corresponding to the unit pressure range at the second time based on the compressor capacity, the time difference, and the first hydrogen mass; determining the second target cost corresponding to the unit pressure range at the second time based on the compressor capacity, the time difference, the compressor power, the compressor electricity cost, the first target cost, and the hydrogen fixed cost; and determining the second hydrogen cost based on the quotient of the second target cost and the second hydrogen mass. When the first time is the original time and the second time is the current time, the first target cost can be understood as the original cost of the unit pressure range, and the second target cost can be understood as the current cost of the unit pressure range.
[0063] In some embodiments, determining the second hydrogen mass corresponding to the unit pressure range at the second time based on the compressor capacity, the time difference, and the first hydrogen mass includes: determining the third hydrogen mass based on the product of the compressor capacity and the time difference; and determining the second hydrogen mass based on the sum of the first hydrogen mass and the third hydrogen mass.
[0064] In some implementations, determining the second target cost corresponding to the unit pressure range at the second time based on the compressor capacity, the time difference, the compressor power, the compressor electricity cost, the first target cost, and the hydrogen fixed cost includes: determining a third target cost based on the product of the hydrogen fixed cost and the third hydrogen mass; determining a fourth target cost based on the product of the compressor electricity cost, the compressor power, and the time difference; and determining the second target cost based on the sum of the third target cost, the fourth target cost, and the first target cost. Electricity costs may vary at different times, resulting in different compressor electricity costs within different time periods. For example, daytime electricity costs may be higher than nighttime compressor electricity costs. Based on the current compressor electricity cost, a second hydrogen cost is determined, and this second hydrogen cost replaces the first hydrogen cost as the current hydrogen cost, updating the hydrogen cost and improving the accuracy of hydrogen cost calculation.
[0065] In some implementations, determining the fourth target cost based on the product of the compressor electricity cost, the compressor power, and the time difference includes: determining a weighting coefficient corresponding to the unit pressure range; and determining the fourth target cost based on the product of the compressor electricity cost, the compressor power, the time difference, and the weighting coefficient. The product of the compressor electricity cost, the compressor power, and the time difference can be understood as the target electricity cost within a target time period, and the fourth target cost can be understood as a weighted calculation of the target electricity cost according to the weighting coefficient, thereby including the added value corresponding to the unit pressure range in the hydrogen cost.
[0066] In some implementations, the larger the pressure value of the unit pressure range, the larger the weighting coefficient. The larger the pressure value of the unit pressure range, the higher its added value, and therefore the larger its weighting coefficient.
[0067] In some implementations, with the goal of maximizing the profitability of hydrogen refueling stations, the weighting coefficients are adjusted based on the actual operation of the hydrogen refueling stations, financial data, and customer flow.
[0068] In some implementations, the formula for calculating the second hydrogen cost corresponding to the unit pressure range is as follows: Among them, cf i Let cs be the cost of the second hydrogen gas in the i-th unit pressure range. i M represents the first hydrogen cost for the i-th unit pressure range. i Let J be the mass of hydrogen gas in the first unit pressure range, J be the compressor power, t be the time difference, and ce be the mass of hydrogen gas in the first unit pressure range. t For the compressor electricity cost, Co i J is the weighting coefficient for the i-th unit pressure range, ch is the fixed cost of hydrogen, and K is the compressor capacity. If the hydrogen compressor is not running, then J and K are zero, and cf... i =cs i .
[0069] In some implementations, in cf i and CS i The unit is yuan / kg, M i The unit for is kg, the unit for J is kW, the unit for t is s, and the unit for ce is s. t When the unit of is yuan / kWh, the unit of ch is yuan, and the unit of K is Nm3 / h, the calculation formula for the second hydrogen cost corresponding to the unit pressure range is as follows: Among them, 0.0002778 and 0.000024786 are coefficients generated during unit conversion.
[0070] In some embodiments, determining the first hydrogen mass and first hydrogen cost corresponding to the unit pressure range at the first time includes: at the first time, acquiring the current temperature of the hydrogen storage tank, the current volume of the hydrogen storage tank, and the first hydrogen cost; determining a first lower pressure limit value for the unit pressure range and a second lower pressure limit value for the next unit pressure range, wherein the next unit pressure range is greater than the unit pressure range; determining the first density based on the current temperature and the first lower pressure limit value; determining the second density based on the current temperature and the second lower pressure limit value; determining a density difference based on the difference between the second density and the first density; and determining the first hydrogen mass based on the product of the density difference and the current volume.
[0071] In some implementations, the first hydrogen cost is determined according to the method for determining the hydrogen cost of a hydrogen refueling station, for example, based on the hydrogen cost at a third time prior to the first time.
[0072] In some embodiments, the formula for determining the mass of the first hydrogen gas is as follows: M i =(d(Tf,P i+1 )-d(Tf,P i ))*V, where d(Tf,P i+1 ) represents the second density of the i-th unit pressure interval, characterized by Tf and P i+1 The function for calculating the second density, d(Tf,P) i Let be the first density of the i-th unit pressure range, characterized by Tf and P. i The function for calculating the first density, where V is the current volume, Tf is the current temperature, and P... i+1 P is the lower limit of the pressure in the (i+1)th unit pressure interval. i This represents the lower limit of pressure for the i-th unit pressure range.
[0073] In some implementations, when the hydrogen refueling station has multiple storage tanks, the formula for determining the mass of the first hydrogen gas is as follows: Among them, M ij Let represent the first hydrogen mass corresponding to the i-th unit pressure range of the j-th hydrogen storage tank, and n represent the number of hydrogen storage tanks.
[0074] In some implementations, during the process of filling the hydrogen storage tank from zero to full, the initial hydrogen mass and initial hydrogen cost are both set to 0, i.e., M. i and CS iThe initial pressure is 0. During the refueling process, the pressure in the hydrogen storage tank gradually increases over time. The hydrogen mass and cost corresponding to the first unit pressure interval increase first. After the pressure in the hydrogen storage tank exceeds the upper limit of the first unit pressure interval, the hydrogen mass and cost corresponding to the second unit pressure interval begin to increase. The pressure in the hydrogen storage tank reaches the pressure corresponding to when it is full. To determine the second hydrogen cost corresponding to the first unit pressure interval, the process is as follows: First, the time when the hydrogen storage tank starts refueling from zero is taken as the first time interval (second 0), and the first second is taken as the second time interval. This determines the second hydrogen cost corresponding to the first unit pressure interval at the first second after the first time interval. Second, the first second is taken as the first time interval, and the second second is taken as the second time interval. This again determines the second hydrogen cost corresponding to the first unit pressure interval at the second second. Finally, through iterative calculations, this process continues until the pressure in the hydrogen storage tank reaches the pressure corresponding to when it is full.
[0075] It should be noted that after the gas pressure in the hydrogen storage tank exceeds the upper limit of the first unit pressure range, the cost of the second hydrogen gas corresponding to the first unit pressure range remains unchanged, and so on, and so on for the Nth unit pressure range, where N is the number of unit pressure ranges.
[0076] In some implementations, the second hydrogen cost is determined in 1-second cycles. For example, the first time is the 1st second, the second time is the 2nd second, the second hydrogen cost in the 2nd second is determined based on the first hydrogen cost in the 1st second, and then the second hydrogen cost in the 3rd second is determined based on the first hydrogen cost in the 2nd second, and so on. The first hydrogen cost in the 2nd second is the second hydrogen cost in the 2nd second.
[0077] In some implementations, the compressor capacity is 500 N / m. 3 The hydrogen refueling station is equipped with a hydrogen storage tank group consisting of 12 identical hydrogen storage tanks that operate in a single, simultaneous manner. The tanks have a design pressure of 49.5 MPa, a maximum operating pressure of 45 MPa, and a volume of 1 m³. 3 Before the hydrogen compressor adds hydrogen to the storage tank, the pressure in the storage tank is 34 MPa. After adding hydrogen, the pressure in the storage tank is between 41 and 42 MPa. The adding time is 1 hour. According to the method for determining the hydrogen cost of a hydrogen refueling station, Table 1 is obtained. In Table 1, 1 represents the unit pressure range of 0-1 MPa, and 45 represents the unit pressure range of 44-45 MPa. Referring to Table 1, the first hydrogen cost and the second hydrogen cost are the same for the unit pressure range of 1 to 34. The first hydrogen cost and the second hydrogen cost are different for the unit pressure range of 35 to 42 because the pressure change of the storage tank is from 34 MPa to 41 MPa.
[0078] Table 1
[0079]
[0080]
[0081] In some implementations, the selling price corresponding to a unit pressure range is determined based on the sum of the second hydrogen cost, a preset profit, and preset taxes. Different selling prices can be used for different unit pressure ranges; the higher the pressure within the unit pressure range, the higher the selling price. When users need rapid refueling, hydrogen from a higher pressure unit pressure range is required, and its selling price is higher. Therefore, to accommodate different users' refueling time requirements, hydrogen refueling stations can provide multiple refueling modes based on the selling price within the unit pressure range, corresponding to different refueling times and fees. The rule is that the shorter the refueling time, the higher the refueling fee.
[0082] In this application, for a unit pressure range, the second hydrogen cost for the second time is determined based on the first hydrogen cost at the first time, the time difference, and the hydrogen compressor parameters within the target time period. This updates the hydrogen cost for the unit pressure range, i.e., the hydrogen cost at the current time is determined based on the hydrogen cost at the previous time, thus achieving accurate calculation of the hydrogen cost for the hydrogen refueling station.
[0083] According to a second aspect of this application, a method for determining the hydrogen cost of a hydrogen refueling station is provided, comprising: obtaining a pressure threshold and a fixed value; when the upper limit of the unit pressure range is less than or equal to the pressure threshold, the hydrogen cost corresponding to the unit pressure range is a fixed value; when the upper limit of the unit pressure range is greater than the pressure threshold, determining the hydrogen cost corresponding to the unit pressure range according to the method described in any embodiment of the first aspect above.

[0086] The first determining unit 102 determines the first hydrogen mass and the first hydrogen cost corresponding to the unit pressure range at the first time.
[0087] The acquisition unit 103 acquires the fixed cost of hydrogen, the parameters of the hydrogen compressor within a target time period, and the time difference, wherein the target time period is the time period from the first time to the second time, the time difference is the difference between the second time and the first time, and the second time is after the first time.
