The method can be implemented by a computer program, which can be integrated into an application or run as an independent tool application. The method can also be implemented by a single-chip microcomputer or run on a hydrogen fuel cell control system based on a von Neumann system. Specifically, the method can include the following steps:

[0028] Step 101: Obtain gas flow data, battery environment data, and power generation data of a hydrogen fuel cell.

[0029] Among them, the gas flow data refers to the flow information of hydrogen and oxygen entering the hydrogen fuel cell. In the embodiment of the present application, it can be understood as the numerical values ​​of the hydrogen flow and oxygen flow obtained by measuring the flow meter, and the calculated hydrogen and oxygen consumption data, which are used to determine the gas utilization rate and gas flow ratio of the hydrogen fuel cell.

[0030] Battery environment data refers to parameters that reflect the internal operating environment of a hydrogen fuel cell. In the embodiment of the present application, it can be understood as the temperature and pressure of the battery reaction zone measured by a temperature sensor and a pressure sensor, which are used to compensate for the power generation efficiency of the battery.

In the embodiment of the present application, it can be understood as the battery output current and output voltage obtained by measuring the current and voltage tester, which are used to calculate the output power and power generation efficiency of the hydrogen fuel cell.

[0032] Specifically, the gas flow data, battery environment data and power generation data of the hydrogen fuel cell are obtained in order to provide the basic parameters required for the subsequent generation of the power generation energy efficiency curve. Among them, the gas flow data reflects the flow information of the input hydrogen and oxygen, and is the basis for determining the gas utilization rate and the gas flow ratio; the temperature and pressure in the battery environment data will affect the electrochemical reaction of the battery and need to be used to compensate for the power generation efficiency; the power generation data reflects the real-time power generation of the battery and can calculate the power generation efficiency. By setting a gas flow meter to measure the hydrogen flow and oxygen flow entering the hydrogen fuel cell, and detecting the total gas flow entering the battery at the same time; setting a temperature and pressure sensor to monitor the temperature and pressure of the battery reaction zone in real time; setting a current and voltage tester to measure the output current and voltage of the battery. The purpose of obtaining gas flow data, battery environment data and power generation data is to comprehensively reflect the battery operation status, consider a variety of factors that affect the power generation effect, and through the comprehensive analysis of these data, guide the precise control of the battery to achieve efficient power generation.

[0033] Step 102: Determine the power generation efficiency of the hydrogen fuel cell based on the power generation data, and determine the gas flow ratio of the hydrogen fuel cell based on the oxygen flow and hydrogen flow in the gas flow data.

[0034] Among them, power generation efficiency refers to the efficiency of a hydrogen fuel cell in converting input chemical energy into electrical energy. In the embodiment of the present application, it can be understood as the ratio of the output power of the battery to the chemical energy of the consumed hydrogen, which is used to evaluate the power generation performance of the battery.

[0035] Oxygen flow rate and hydrogen flow rate refer to the volume flow rate of oxygen and hydrogen entering the hydrogen fuel cell. In the embodiment of the present application, it can be understood as the flow values ​​of oxygen and hydrogen obtained by measuring the flow meters set in the hydrogen and oxygen input pipelines, which are used to calculate the utilization rate of hydrogen and oxygen, and then determine the gas flow ratio of the hydrogen fuel cell.

[0036] The gas flow ratio refers to the ratio of the hydrogen flow to the oxygen flow in a hydrogen fuel cell. In the embodiment of the present application, it can be understood as the ratio of the hydrogen consumption to the oxygen consumption calculated based on the utilization rates of hydrogen and oxygen, and is used to indicate the gas usage ratio status of the battery.

[0037] Specifically, the power generation efficiency of the hydrogen fuel cell is determined based on the power generation data, and the gas flow ratio of the hydrogen fuel cell is determined based on the gas flow data, in order to obtain two key parameters required in the power generation energy efficiency curve.

[0038] After receiving the output voltage and output current in the power generation data, the output power is calculated, and the power generation efficiency per unit of hydrogen consumption is determined in combination with the hydrogen consumption and the calibrated conversion efficiency, which is used as one of the parameters for the subsequent generation of the power generation energy efficiency curve. After receiving the hydrogen flow and oxygen flow in the gas flow data, the gas flow ratio calculation module calculates the utilization rate of each gas, and then calculates the consumption of hydrogen and oxygen, and then obtains the ratio of the actual consumption of hydrogen to oxygen, that is, the gas flow ratio, as the second parameter for the subsequent generation of the power generation energy efficiency curve. The power generation efficiency and gas flow ratio are determined to fully reflect the power generation performance and gas usage status of the battery. Combined with the subsequent environmental compensation parameters, a power generation energy efficiency curve that more accurately reflects the actual operation law of the battery can be generated, providing a basis for optimizing battery control.

[0039] Based on the above embodiment, as an optional embodiment, in step 102: determining the power generation efficiency of the hydrogen fuel cell according to the power generation data, this step may also include the following steps:

[0040] Step 201: Determine the output power of the hydrogen fuel cell based on the output voltage and output current in the power generation data.

[0041] Among them, the output voltage and output current refer to the voltage and current parameters at the output end of the hydrogen fuel cell after power generation. In the embodiment of the present application, it can be understood as the battery output voltage value and output current value obtained by measuring the current and voltage tester set at the output end of the battery, which are used to calculate the output power of the hydrogen fuel cell.

[0042] Output power refers to the power generated by a hydrogen fuel cell during the power generation process. In the embodiment of the present application, it can be understood as the instantaneous output power value of the hydrogen fuel cell calculated based on the output voltage and output current in the power generation data, which is used to calculate the power generation efficiency of the hydrogen fuel cell.

[0043] Specifically, the output power of the hydrogen fuel cell is determined based on the output voltage and output current in the power generation data in order to calculate the output power parameters required for power generation efficiency. The output voltage and output current of the hydrogen fuel cell are measured and collected in real time through the current and voltage tester. The output voltage reflects the operating voltage of the battery, and the output current reflects the output current provided by the battery. After receiving the output voltage and output current, the output power value of the hydrogen fuel cell is calculated and determined according to the output power formula, that is, the product of the output voltage and the output current. After obtaining the output power, the power generation efficiency calculation module can calculate the output power generated by the unit hydrogen consumption, that is, the power generation efficiency, which reflects the power generation capacity of the battery.

[0044] Step 202: Obtain the calibrated conversion efficiency of the hydrogen fuel cell; determine the calorific value of the hydrogen fuel cell based on the hydrogen consumption in the gas flow data and the calibrated conversion efficiency.

[0045] Among them, the calibrated conversion efficiency refers to the efficiency of converting the input chemical energy of a hydrogen fuel cell into electrical energy under standard test conditions, which is determined through a prior calibration test. In the embodiment of the present application, it can be understood as a reference efficiency value that reflects the effect of converting the battery input energy into electrical energy.

[0046] Hydrogen consumption refers to the amount of hydrogen actually consumed by a hydrogen fuel cell during the power generation process. In the embodiment of the present application, it can be understood as the molar amount of hydrogen participating in the battery reaction per unit time calculated based on the hydrogen flow data and utilization rate, which is used to calculate the input chemical energy of the hydrogen fuel cell.

[0047] Calorific value refers to the chemical energy that can be released after each mole of hydrogen in a hydrogen fuel cell is completely reacted. In the embodiment of the present application, it can be understood as the amount of chemical energy generated per unit mole of hydrogen calculated based on the calibrated conversion efficiency, which is used to calculate the input chemical energy of the hydrogen fuel cell.

[0048] Specifically, obtaining the calibrated conversion efficiency of the hydrogen fuel cell and determining the calorific value of the hydrogen fuel cell based on the hydrogen consumption and the calibrated conversion efficiency are to calculate the input chemical energy parameters required for power generation efficiency. The conversion efficiency data of the hydrogen fuel cell calibrated under standard test conditions is obtained. The conversion efficiency reflects the effect of converting input energy into electrical energy. Then, based on the hydrogen consumption in the known gas flow data and the pre-stored calibrated conversion efficiency, the chemical energy released by the complete reaction of a unit mole of hydrogen, that is, the calorific value of hydrogen, can be determined. After obtaining the calorific value, the input chemical energy can be calculated based on the hydrogen consumption, combined with the output power, to calculate the power generation efficiency and evaluate the actual power generation performance of the battery. Obtaining the calibrated conversion efficiency and determining the calorific value are the basis for calculating the power generation efficiency. Accurately obtaining the input chemical energy and comparing the output electrical energy can objectively evaluate the actual power generation effect of the hydrogen fuel cell.

[0049] Step 203: Divide the output power by the calorific value to obtain the power generation efficiency of the hydrogen fuel cell.

[0050] Specifically, the power generation efficiency of the hydrogen fuel cell is obtained by dividing the output power by the calorific value in order to calculate the important parameter of power generation efficiency based on the output electrical energy and input chemical energy. After obtaining the output power and calorific value, the ratio of the two is taken, that is, the output power is divided by the calorific value, and the output power generated by the hydrogen fuel cell consuming unit hydrogen can be obtained, which reflects the effect of the battery's input chemical energy converted into output electrical energy, that is, the power generation efficiency. The power generation efficiency directly reflects the power generation performance of the battery. The larger the value, the better the power generation effect. Accurately obtaining the power generation efficiency can evaluate the actual power generation level of the battery. Combined with parameters such as the gas flow ratio, a power generation energy efficiency curve is generated to provide a basis for subsequent control optimization. By calculating the power generation efficiency, the power generation capacity and gas utilization effect of the battery can be comprehensively considered, and the actual operating conditions of the battery can be more accurately evaluated.

[0051] Based on the above embodiment, as an optional embodiment, in step 102: determining the gas flow ratio of the hydrogen fuel cell according to the oxygen flow rate and the hydrogen flow rate in the gas flow data, this step may also include the following steps:

[0052] Step 204: Obtain a first utilization rate of a cathode plate and a second utilization rate of an anode plate in a hydrogen fuel cell.

[0053] Among them, the first utilization rate of the battery cathode plate refers to the percentage of hydrogen entering the cathode plate in the hydrogen fuel cell that actually participates in the reaction. In the embodiment of the present application, it can be understood as the data on the cathode plate hydrogen utilization effect obtained through calibration testing, which is used to calculate the actual consumption of hydrogen.

[0054] The second utilization rate of the battery anode plate refers to the percentage of oxygen entering the anode plate in the hydrogen fuel cell that actually participates in the reaction. In the embodiment of the present application, it can be understood as the data on the oxygen utilization effect of the anode plate obtained through calibration testing, which is used to calculate the actual consumption of oxygen.

[0055] Specifically, obtaining the first utilization rate of the battery cathode plate and the second utilization rate of the battery anode plate in the hydrogen fuel cell is to calculate the utilization rates of hydrogen and oxygen, and then determine the parameter of the gas flow ratio. The first utilization rate of the cathode plate and the second utilization rate of the anode plate measured during the battery calibration test are obtained from the storage unit. Among them, the first and second utilization rates respectively reflect the actual reaction utilization rates of hydrogen and oxygen in the battery. After obtaining these two utilization rates, they can be multiplied with the subsequently measured hydrogen and oxygen flow rates to calculate the hydrogen and oxygen consumption of each reaction in the battery, and further the hydrogen and oxygen consumption ratio, that is, the gas flow ratio, can be obtained to reflect the battery gas usage status.

[0056] Step 205: Determine a target hydrogen flow rate of the hydrogen fuel cell based on the first utilization rate and the hydrogen flow rate, and determine a target oxygen flow rate of the hydrogen fuel cell based on the second utilization rate and the oxygen flow rate.

[0057] Among them, the target hydrogen flow rate refers to the amount of hydrogen actually consumed by the cathode plate of the hydrogen fuel cell. In the embodiment of the present application, it can be understood as the molar amount of hydrogen actually participating in the reaction in the cathode plate calculated based on the first utilization rate and the measured hydrogen flow rate, which is used to calculate the hydrogen-oxygen flow ratio.

[0058] The target oxygen flow rate refers to the amount of oxygen actually consumed by the anode plate of the hydrogen fuel cell. In the embodiment of the present application, it can be understood as the molar amount of oxygen actually participating in the reaction in the anode plate calculated based on the second utilization rate and the measured oxygen flow rate, which is used to calculate the hydrogen-oxygen flow rate ratio.

[0059] Specifically, the target hydrogen flow rate is determined based on the first utilization rate and the hydrogen flow rate, and the target oxygen flow rate is determined based on the second utilization rate and the oxygen flow rate, in order to calculate the actual consumption of hydrogen and oxygen, and then determine the parameter of the gas flow ratio. According to the known first utilization rate of the cathode plate hydrogen and the measured inlet hydrogen flow rate, the actual amount of hydrogen consumed inside the cathode plate, that is, the target hydrogen flow rate, can be calculated by multiplying the two. Similarly, according to the known second utilization rate of the anode plate oxygen and the measured inlet oxygen flow rate, the actual amount of oxygen consumed inside the anode plate, that is, the target oxygen flow rate, can be calculated by multiplying the two. After obtaining the target hydrogen flow rate and the target oxygen flow rate, the ratio of the two is calculated to determine the hydrogen and oxygen flow ratio, evaluate the gas utilization effect inside the battery, and by calculating the target hydrogen and oxygen flow rates, the actual gas consumption of the battery can be fully reflected.

[0060] Step 206: The ratio of the target hydrogen flow rate to the target oxygen flow rate is used as the gas flow rate ratio of the hydrogen fuel cell.

[0061] Specifically, the ratio of the target hydrogen flow rate to the target oxygen flow rate is used as the gas flow ratio of the hydrogen fuel cell in order to evaluate the use effect of the gas inside the battery by comparing the target hydrogen and oxygen flow rates. After calculating the target hydrogen flow rate and the target oxygen flow rate, the ratio of the two is taken, that is, the target hydrogen flow rate is divided by the target oxygen flow rate, to obtain the consumption ratio of the hydrogen and oxygen gases inside the hydrogen fuel cell. This ratio reflects the use status of the hydrogen and oxygen gases in the battery. The closer the value is to 1, the better the utilization effect of the hydrogen and oxygen gases. Accurately calculating the gas flow ratio can evaluate the reaction of the hydrogen and oxygen gases inside the battery. Compared with the original flow data of the gas flowing through the battery, the gas utilization effect can be judged, which improves the data basis for the subsequent control of the hydrogen fuel cell.

[0062] Step 103: Based on the reaction temperature and reaction pressure in the battery environment data, environmental compensation is performed on the power generation efficiency to obtain the target power generation efficiency of the hydrogen fuel cell.

[0063] Among them, the reaction temperature and reaction pressure refer to the operating temperature and operating pressure inside the hydrogen fuel cell respectively, which can be understood as the temperature and pressure parameters in the battery reaction process in the embodiment of the present application, and are used to perform environmental compensation for power generation efficiency.

[0064] Environmental compensation refers to eliminating the influence of reaction temperature and reaction pressure on the calculation of power generation efficiency. In the embodiment of the present application, it can be understood as correcting the power generation efficiency through temperature compensation and pressure compensation to obtain the power generation efficiency under standard conditions.

[0065] The target power generation efficiency refers to the power generation efficiency of the hydrogen fuel cell under standard temperature and pressure conditions. In the embodiment of the present application, it can be understood as the power generation efficiency after eliminating the influence of temperature and pressure through environmental compensation, which is used to evaluate and analyze the power generation performance of the hydrogen fuel cell.

[0066] Specifically, environmental compensation is performed on the power generation efficiency based on the reaction temperature and reaction pressure to obtain the target power generation efficiency in order to eliminate the influence of temperature and pressure changes on the calculation of power generation efficiency and obtain the power generation efficiency under standard conditions. The reaction temperature and reaction pressure data are obtained during the operation of the hydrogen fuel cell. Then, the calculated power generation efficiency is corrected according to the preset temperature compensation model and pressure compensation model. This is because changes in temperature and pressure will affect the electrochemical reaction inside the battery, resulting in a certain deviation in the power generation efficiency. Environmental compensation can eliminate the influence of temperature and pressure changes and obtain the power generation efficiency under standard conditions, that is, the target power generation efficiency. The target power generation efficiency is an important parameter for evaluating the power generation performance of the battery. Accurate environmental compensation is very important for obtaining the power generation efficiency under standard conditions, and provides a basis for subsequent battery health status assessment and optimization control.

[0067] Based on the above embodiment, as an optional embodiment, in step 103: based on the reaction temperature and reaction pressure in the battery environment data, the power generation efficiency is environmentally compensated to obtain the target power generation efficiency of the hydrogen fuel cell. This step may also include the following steps:

[0068] Step 301: subtract the preset standard temperature from the reaction temperature to obtain a temperature difference, and divide the reaction pressure by the preset standard pressure to obtain a pressure ratio.

[0069] Among them, the preset standard temperature refers to the standard temperature condition for measuring the power generation efficiency of hydrogen fuel cells. In the embodiment of the present application, it can be understood as the temperature reference value set in the environmental compensation process, which is used to compare with the actual reaction temperature and calculate the temperature difference.

[0070] The preset standard pressure refers to the standard pressure condition for measuring the power generation efficiency of a hydrogen fuel cell. In the embodiment of the present application, it can be understood as a pressure reference value set during the environmental compensation process, which is used to compare with the actual reaction pressure and calculate the pressure ratio.

[0071] Specifically, the reaction temperature is subtracted from the preset standard temperature to obtain the temperature difference, and the reaction pressure is divided by the preset standard pressure to obtain the pressure ratio, in order to obtain the deviation data of the temperature and pressure from the standard state, which serves as the basis for the subsequent environmental compensation model. The reaction temperature and reaction pressure during the operation of the hydrogen fuel cell are measured. Then, the measured reaction temperature value is subtracted from the preset standard temperature value to calculate the temperature difference between the two. At the same time, the measured reaction pressure value is divided by the preset standard pressure value to calculate the pressure ratio between the two. After obtaining the temperature difference and pressure ratio, the power generation efficiency can be temperature compensated and pressure compensated according to the mapping relationship between these two parameters and the power generation efficiency.

[0072] Step 302: In the environmental compensation factor library, match the temperature compensation factor corresponding to the temperature difference and the pressure compensation factor corresponding to the pressure ratio.

[0073] Among them, the environmental compensation factor library refers to a database that stores corresponding compensation factors under different temperature and pressure conditions. In the embodiment of the present application, it can be understood as a table that stores temperature compensation factors corresponding to various temperature differences and pressure compensation factors corresponding to pressure ratios, which is used to obtain compensation factors that match the actual temperature and pressure deviations.

[0074] The temperature compensation factor refers to a correction coefficient used to compensate for power generation efficiency under different temperature conditions. In the embodiment of the present application, it can be understood as a value that matches the measured temperature difference and is used to correct the power generation efficiency.

[0075] The pressure compensation factor refers to a correction coefficient used to compensate for power generation efficiency under different pressure conditions. In the embodiment of the present application, it can be understood as a value that matches the measured pressure ratio and is used to correct the power generation efficiency.

[0076] Specifically, in the environmental compensation factor library, the temperature compensation factor corresponding to the temperature difference and the pressure compensation factor corresponding to the pressure ratio are matched in order to find the corresponding compensation coefficient according to the calculated temperature and pressure deviation value, which is used for the subsequent accurate environmental compensation of the power generation efficiency. The temperature difference and pressure ratio are calculated. Then, the temperature compensation factor that matches the temperature difference value and the pressure compensation factor that matches the pressure ratio are searched in the preset environmental compensation factor library. The environmental compensation factor library has obtained the compensation factors under different temperature and pressure conditions through a large number of experiments. Obtaining the compensation factor according to the actual temperature and pressure deviation matching is a key step in building an accurate compensation model. By obtaining the temperature and pressure compensation factors that are consistent with the actual situation, an accurate environmental compensation model can be established, which can effectively eliminate the influence of temperature and pressure changes on the calculation of power generation efficiency and obtain the target power generation efficiency under standard conditions.

[0077] Step 303: Multiply the temperature compensation factor and the pressure compensation factor to obtain an environmental compensation coefficient for the hydrogen fuel cell.

[0078] Among them, the environmental compensation coefficient refers to the power generation efficiency correction coefficient that comprehensively considers the influence of temperature and pressure. In the embodiment of the present application, it can be understood as the compensation value obtained by multiplying the temperature compensation factor and the pressure compensation factor, which is used to construct a complete environmental compensation model to correct the power generation efficiency.

[0079] Specifically, the temperature compensation factor is multiplied by the pressure compensation factor to obtain the environmental compensation coefficient, which is to comprehensively consider the influence of temperature and pressure factors and accurately calculate the target power generation efficiency. The temperature compensation factor and pressure compensation factor that match the calculated temperature difference and pressure ratio are obtained from the environmental compensation factor library. Then the numerical multiplication is performed to obtain the environmental compensation coefficient that reflects the comprehensive influence of temperature and pressure. The reason for this is that both temperature and pressure changes will affect the power generation efficiency. Both factors must be considered to accurately eliminate the influence of environmental changes on the power generation efficiency. By calculating the environmental compensation coefficient, the temperature and pressure factors can be comprehensively considered to accurately obtain the target power generation efficiency under standard conditions.

[0080] Step 304: Multiply the power generation efficiency by the environmental compensation coefficient to obtain the target power generation efficiency of the hydrogen fuel cell.

[0081] Specifically, the power generation efficiency is multiplied by the environmental compensation coefficient to obtain the target power generation efficiency in order to use the environmental compensation coefficient to eliminate the influence of temperature and pressure changes and accurately calculate the power generation efficiency of the hydrogen fuel cell under standard conditions. The uncompensated power generation efficiency is calculated and then numerically multiplied by the obtained environmental compensation coefficient, that is, the multiplication of the power generation efficiency and the compensation coefficient. The result of the operation is the target power generation efficiency after eliminating the environmental impact. This is because the environmental compensation coefficient comprehensively considers the influence of temperature and pressure factors. Multiplying it with the power generation efficiency can eliminate the influence of environmental changes and accurately obtain the power generation efficiency of the hydrogen fuel cell under standard conditions, that is, the target power generation efficiency.

[0082] Step 104: Generate a power generation efficiency curve of the hydrogen fuel cell by combining the target power generation efficiency and the gas flow ratio.

[0083] Among them, the power generation energy efficiency curve refers to a curve chart that reflects the relationship between the target power generation efficiency and the gas flow ratio of the hydrogen fuel cell under different load conditions. In the embodiment of the present application, it can be understood as a curve drawn according to the target power generation efficiency obtained by measuring different gas flow ratios, which is used to evaluate the power generation performance of the battery under various load conditions.

[0084] Specifically, the power generation efficiency curve is generated by combining the target power generation efficiency and the gas flow ratio to comprehensively evaluate the actual power generation performance of hydrogen fuel cells under different load conditions. According to the measured gas flow ratio, the power generation efficiency under different load conditions is calculated. Then it is multiplied by the environmental compensation coefficient obtained previously to eliminate the environmental impact and obtain the target power generation efficiency under each load condition. Next, with the gas flow ratio as the horizontal axis and the target power generation efficiency as the vertical axis, a relationship curve is drawn to form a power generation efficiency curve. This is done to examine the power generation effect of hydrogen fuel cells under a full range of load conditions. The power generation efficiency curve can intuitively reflect the health status of the battery.

[0085] Based on the above embodiment, as an optional embodiment, in step 104: combining the target power generation efficiency and the gas flow ratio to generate a power generation energy efficiency curve of the hydrogen fuel cell, this step may also include the following steps:

[0086] Step 401: According to the timestamps of the target power generation efficiency and the gas flow ratio, the target power generation efficiency and the gas flow ratio are divided into target power generation efficiencies and gas flow ratios corresponding to a plurality of different time points.

[0087] Among them, the timestamp refers to the time point information corresponding to the acquisition of parameter data. In the embodiment of the present application, it can be understood as the time mark when the target power generation efficiency and gas flow ratio data are acquired, which is used to divide the data into different time periods according to the time sequence.

[0088] The time point refers to the specific time when the parameter data is obtained. In the embodiment of the present application, it can be understood as the time mark corresponding to the acquisition of the target power generation efficiency and gas flow ratio data. It is used to represent data sets in different time periods and evaluate the dynamic response performance of the battery in different time periods.

[0089] Specifically, according to the data timestamps of the target power generation efficiency and gas flow ratio, they are divided into multiple data sets at different time points in order to obtain the power generation parameters of the battery under various load conditions in different time periods and establish a data foundation for subsequent time responsiveness analysis. The target power generation efficiency and gas flow ratio data and their timestamps are read, and then the data is divided into multiple data sets in chronological order according to the timestamp information. Each data set contains the target power generation efficiency and gas flow ratio scanned in a time period. This is done because it is necessary to collect the real-time power generation parameters of the battery under various loads in different time periods for analyzing the instantaneous response performance of the battery.

[0090] Step 402: With the target power generation efficiency as the ordinate and the gas flow rate ratio as the abscissa, the target power generation efficiency and the gas flow rate ratio corresponding to each time point are fitted to obtain a power generation energy efficiency curve of the hydrogen fuel cell.

[0091] Specifically, with the target power generation efficiency as the ordinate and the gas flow ratio as the abscissa, the data at each time point are fitted to obtain the power generation energy efficiency curve, in order to draw the power generation performance curve of the battery under various load conditions in different time periods and evaluate the time response characteristics of the battery. Take the target power generation efficiency and gas flow ratio data in the same time period, with the gas flow ratio as the abscissa and the target power generation efficiency as the ordinate, and use the curve fitting method to obtain the power generation energy efficiency curve of the time period. Repeat the above process to obtain the power generation energy efficiency curves for multiple time periods. This is done to analyze the parameter changes and response characteristics of the battery power generation performance in different time periods. Multiple sets of power generation energy efficiency curves can evaluate the dynamic response performance of the battery under instantaneous load changes, and obtain power generation energy efficiency curves for different time periods. It is possible to observe the changes in battery performance over time and analyze the time response characteristics of the battery.

[0092] Step 105: When the current power generation efficiency of the hydrogen fuel cell is less than the power generation efficiency threshold, determine the target parameter control point in the power generation energy efficiency curve, and adjust the hydrogen fuel cell based on the flow ratio corresponding to the target parameter control point.

[0093] Among them, the power generation efficiency threshold refers to the standard value for judging whether the power generation efficiency of the hydrogen fuel cell is too low. In the embodiment of the present application, it can be understood as a pre-set lower limit of the power generation efficiency, which is used to judge whether the current power generation efficiency of the battery is lower than the normal operating range, so as to decide whether parameter adjustment optimization is needed.

[0094] The target parameter control point refers to a reference point on the power generation energy efficiency curve that has an optimization effect. In the embodiment of the present application, it can be understood as a corresponding point of the gas flow ratio with relatively high power generation efficiency, which is used to guide the adjustment of battery parameters to improve the power generation efficiency.

[0095] Specifically, when the current power generation efficiency of the hydrogen fuel cell is lower than the preset power generation efficiency threshold, the target parameter control point on the power generation energy efficiency curve is determined, and the hydrogen fuel cell is adjusted according to the gas flow ratio corresponding to the control point, so as to improve the power generation efficiency through parameter optimization when the efficiency is reduced. The current power generation efficiency is detected and compared with the set efficiency threshold. If the actual efficiency is found to be low, a target parameter control point is selected in the power generation energy efficiency curve, and the gas flow ratio of this point corresponds to a higher power generation efficiency. Then, the supply of hydrogen and air is adjusted according to the gas flow ratio of the control point to optimize the battery operating parameters. This is done so that when the efficiency decreases, the battery can be restored to a better state by adjusting the parameters to avoid continuous deterioration of efficiency. By selecting a suitable control point and adjusting the flow ratio, the battery operating conditions can be optimized in time to ensure its stable and lasting power generation effect.

[0096] Based on the above embodiment, as an optional embodiment, in step 105: when the current power generation efficiency of the hydrogen fuel cell is less than the power generation efficiency threshold, determining the target parameter control point in the power generation energy efficiency curve, this step may also include the following steps:

[0097] Step 501: Obtain the current power generation efficiency of the hydrogen fuel cell; if the current power generation efficiency of the hydrogen fuel cell is less than the power generation efficiency threshold, traverse a plurality of parameter points corresponding to power generation efficiencies greater than the power generation efficiency threshold in the power generation energy efficiency curve.

[0098] Specifically, the current power generation efficiency of the hydrogen fuel cell is obtained and compared with the preset power generation efficiency threshold. If the current efficiency is lower than the threshold, multiple parameter points corresponding to power generation efficiencies higher than the threshold are traversed on the power generation energy efficiency curve. This is to quickly locate multiple candidate control points that can improve efficiency when the battery efficiency decreases. The current power generation efficiency is detected to check whether it is lower than the set efficiency threshold. If so, multiple parameter points with power generation efficiency higher than the threshold are found on the power generation energy efficiency curve to obtain the gas flow ratio data corresponding to these points. This is done to quickly determine multiple optional control points when the efficiency decreases. The parameter settings of these control points can improve the efficiency and provide a candidate set for the subsequent selection of the optimal control point. Traversing to find multiple feasible control points can narrow the selection range and provide a basis for selecting the optimal parameter settings, quickly optimize the battery parameters, and improve power generation efficiency.

[0099] Step 502: Among the parameter points, select the parameter points whose curve curvature is greater than the curvature threshold as the target parameter control points.

[0100] Among them, the curvature of the curve refers to the degree of curvature of the curve near a certain point. In the embodiment of the present application, it can be understood as the curvature value of the power generation energy efficiency curve at the parameter point, which is used to determine the degree of curvature of the curve near this point and the rate of change of power generation efficiency.

[0101] The curvature threshold refers to the standard value for judging the curvature of a curve. In the embodiment of the present application, it can be understood as a pre-set lower limit of the curvature value, which is used to screen points with curvature greater than the threshold as target parameter control points with large changes in power generation efficiency.

[0102] Specifically, among the multiple parameter points obtained by traversal, the points whose curvature of the power generation energy efficiency curve is greater than the preset curvature threshold are screened out as the target parameter control points, so as to select points with larger changes in power generation efficiency as control points to improve the power generation efficiency more quickly. The curvature value of each candidate parameter point on the power generation energy efficiency curve is calculated, and then it is checked whether the curvature exceeds the preset curvature threshold. If it exceeds the threshold, the point is selected as the final control point. This is done because the larger the curvature, the more drastic the change in power generation efficiency near the point. Selecting points with large curvature as control points and adjusting parameters can improve power generation efficiency more quickly. By selecting suitable control points by the size of the curvature, parameters can be quickly optimized when the efficiency drops, thereby improving the power generation effect of hydrogen fuel cells.

[0103] Based on the above embodiment, as an optional embodiment, in step 105: adjusting the hydrogen fuel cell based on the flow ratio corresponding to the target parameter control point, this step may also include the following steps:

[0104] Step 503: Obtain the current gas flow ratio of the hydrogen fuel cell; based on the flow ratio corresponding to the target parameter control point, adjust the oxygen flow and hydrogen flow of the hydrogen fuel cell until the difference between the current gas flow ratio of the hydrogen fuel cell and the flow ratio corresponding to the target parameter control point is less than a preset error value.

[0105] Specifically, the current gas flow ratio of the hydrogen fuel cell is obtained, and the flow rates of oxygen and hydrogen are adjusted according to the flow ratio corresponding to the selected target parameter control point until the difference between the current flow ratio and the control point flow ratio is less than the preset error value. This is to accurately adjust the battery parameters to the optimal state and maximize the power generation efficiency. The current gas flow ratio is detected and then the difference between the ratio and the target control point flow ratio is calculated. If the difference is greater than the preset allowable error range, the oxygen and hydrogen flow rates are continued to be adjusted so that the current flow ratio approaches the flow ratio of the control point until the difference between the two is less than the error value. This is done to adjust the battery parameters with high precision so that it reaches the optimal power generation state. The closer the control flow ratio is to the optimal flow ratio, the more obvious the improvement in power generation efficiency. By continuously adjusting to approach the optimal flow ratio, the battery power generation efficiency can be maximized and precise parameter optimization control can be achieved.
