Its working principle is mainly to use proton exchange membrane as electrolyte, and produce protons and electrons through the oxidation reaction of hydrogen at the anode. The protons pass through the electrolyte membrane to the cathode to react with oxygen, release electrons and generate water. These electrons flow in the external circuit to form current, thereby driving the electronic devices to work.

[0033] Fuel cell 16: Fuel reacts through a catalyst to generate protons and electrons, thereby forming an electric current in an external circuit to drive electronic devices to work.

[0034] Although a variety of control methods and algorithms have emerged in recent years to control the operating parameters of proton exchange membrane fuel cells, the performance and effect are not ideal.

At the same time, in the application process, the parameters are gradually corrected through machine self-learning and self-optimization, so that the results of the parameters in the mapping relationship table are the optimal parameters of the system.

[0038] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 2 1 is a hardware structure block diagram of a mobile terminal for determining a target power input parameter value according to an embodiment of the present application. Figure 2 As shown, the mobile terminal may include one or more ( Figure 2 Only one is shown in the figure) a processor 202 (the processor 202 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 204 for storing data, wherein the mobile terminal may also include a transmission device 206 and an input / output device 208 for communication functions. It can be understood by those skilled in the art that Figure 2 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 2 More or fewer components as shown, or with Figure 2 Different configurations are shown.

[0039] The memory 204 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for determining the target power input parameter value in the embodiment of the present invention. The processor 202 executes various functional applications and data processing by running the computer program stored in the memory 204, that is, to implement the above method. The memory 204 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 204 may further include a memory remotely arranged relative to the processor 202, and these remote memories may be connected to the mobile terminal via a network. Examples of the above network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0040] The transmission device 206 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 206 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 206 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0041] In this embodiment, a method for determining a target power input parameter value running on the mobile terminal is provided. Figure 3 is a flow chart of a method for adjusting a guide vane valve according to an embodiment of the present application, such as Figure 3 As shown, the process includes the following steps:

[0042] Step S302, obtaining the target power of the target power source;

[0043] The above-mentioned target power source can be any fuel cell, or a device that generates electrical energy after material exchange, such as a proton exchange membrane fuel cell; the above-mentioned target power can be the energy that needs to be provided by the target power source in actual applications, such as the power that needs to be provided by the target power source during the uphill process of a new energy electric vehicle, or the power that needs to be provided by the target power source when an air-cooled unit is running.

[0044] Step S304, determining a target parameter value set matching the target power in a preset mapping table, wherein the mapping table records a correspondence between the power of the target power source and a parameter value set, and the parameter value set includes at least one parameter value;

[0045] The above-mentioned preset mapping table can be a relationship table between a set of values ​​of parameters affecting the target power source and the power output corresponding to the target power source. The parameters affecting the target power source in the mapping table can be one or more. For example, the parameters affecting the output power of the proton exchange membrane fuel cell (PEMFC) include oxygen content, hydrogen content, membrane water content, temperature, and humidity. The preset relationship table of the fuel cell can be shown in Table 1 below:

[0046] Table 1

[0047] Oxygen content Hydrogen content Membrane water content temperature humidity power 20mol 30mol 50％ 40℃ 20％ 100kW 30mol 40mol 60％ 50℃ 30％ 150kW 40mol 50mol 70％ 60℃ 40％ 200kW

[0048] The above-mentioned target parameter set can be a set of parameter values ​​stored in a preset mapping table that matches the target power and has the highest fuel cell output efficiency; through the preset mapping table, the values ​​of the various parameters corresponding to the target power can be quickly found in the mapping table, so that the corresponding parameters are set according to the values ​​of the various parameters, so that the fuel cell can respond quickly and output the target power, thereby improving the reaction speed of the fuel cell, reducing the reaction time of the fuel cell, and avoiding the problem of resource waste caused by mismatched parameter settings.

[0049] Optionally, a target parameter value set matching the target power is determined in a preset mapping table, including: determining a target power range based on the target power, wherein the target power is the minimum value of the target power range, and a difference between the maximum value and the minimum value of the target power range is less than or equal to a preset threshold; determining M powers within the target power range in the mapping table, wherein M is an integer greater than or equal to 1; and determining the target parameter value set through M parameter value sets corresponding to the M powers in the mapping table.

[0050] The above-mentioned target power range can be a power range that matches the target power, the minimum value of the power range is the target power, and the maximum value is a power value whose difference with the target power is less than or equal to a preset threshold, wherein the preset threshold can be set according to actual conditions. For example, during the uphill process of the new energy electric vehicle, when the target power required to be provided by the target power supply is 150kW, the target power range can be 150kW-155kW; according to the target consolidation rate range, multiple powers within the target power range can be determined in the mapping table, such as 151kW, 152kW, and 154kW, and based on the multiple powers and the corresponding parameter value sets, a target parameter value set that can make the fuel cell output efficiency the highest is determined, thereby improving the overall performance of the fuel cell and achieving better energy utilization.

[0051] Step S306: setting the values ​​of the various input parameters of the target power source to the parameter values ​​in the target parameter value set.

[0052] Optionally, the executor of the above steps may be a background processor, or other devices with similar processing capabilities, or a machine that integrates at least an image acquisition device and a data processing device, wherein the image acquisition device may include a graphics acquisition module such as a camera, and the data processing device may include a computer, a mobile phone or other terminal, but is not limited thereto.

[0053] Through the above steps, by presetting the mapping relationship table between the battery output power and the values ​​of each influencing parameter in the system, the operating parameters of the fuel cell can be quickly controlled by looking up the mapping table, so that the output efficiency of the fuel cell is maximized, and the energy consumption of the fuel cell system is effectively reduced. The problem that the output efficiency of the fuel cell cannot be quickly controlled to be maximized in the related art is solved, and the overall efficiency and performance of the fuel cell system are improved.

[0054] As an optional implementation, the target parameter value set is determined by M parameter value sets corresponding to the M powers in the mapping table, including: obtaining the target parameter value in the M parameter value set to obtain M target parameter values, wherein the target parameter value is the parameter value with the highest priority in the parameter value set; obtaining M efficiency values ​​through the M powers and the M target parameter values; and determining the parameter value set corresponding to the largest efficiency value among the M efficiency values ​​as the target parameter value set.

[0055] The above-mentioned target parameter can be the parameter with the highest priority among all parameters, and the target parameter value is the value of the target parameter. For example, for proton exchange membrane fuel cells, hydrogen and oxygen are the main reaction substances of the fuel cell. Since the production cost of hydrogen is much higher than that of oxygen, the hydrogen content can be used as the target parameter of the proton exchange membrane fuel cell; the target parameter value corresponding to the power within the target power range in the preset table is obtained, and the operating efficiency of the fuel cell corresponding to each power can be obtained according to the target parameter value, that is, the amount of target parameter consumed for every 1kW of power generated, and the power value with the highest operating efficiency and its corresponding parameter value set are selected from the obtained operating efficiency, wherein the parameter value set includes the values ​​of all parameters corresponding to the power value with the highest operating efficiency.

[0056] Specifically, M efficiency values ​​are obtained through the M powers and the M target parameter values, including: performing the following operation on each of the M powers: determining the ratio of the current target parameter value to the power of the currently performing operation as the current efficiency value, wherein the M efficiency values ​​include the current efficiency value, the current target parameter value is the target parameter value in the current parameter value set, and the current parameter value set is a parameter value set corresponding to the power of the currently performing operation.

[0057] The power of the currently executed operation may be the output power of the fuel cell when the corresponding parameter value set is used as input; the current target parameter value may be the target parameter value in the corresponding parameter value set; for example, when the target parameter value is the hydrogen content, the hydrogen content is determined as the current target parameter value, and the ratio between the hydrogen content (i.e., the current target parameter value) and the currently output power (i.e., the power of the currently executed operation) is determined as the current efficiency value.

[0058] As an optional implementation, after setting the values ​​of each input parameter of the target power supply to the parameter values ​​in the target parameter value set, it includes: adjusting the values ​​of each input parameter of the target power supply in sequence based on the each parameter value in the target parameter value set, and obtaining the efficiency of the target power supply through the adjusted values ​​of the input parameters; when the efficiency value of the target power supply increases, recording the adjusted parameter value set and the corresponding power in the mapping table.

[0059] The above-mentioned input parameter can be any parameter in the mapping table. For example, the parameters affecting the output power of the proton exchange membrane fuel cell (PEMFC) include oxygen content, hydrogen content, membrane water content, temperature, and humidity. The input parameter can be any parameter among oxygen content, hydrogen content, membrane water content, temperature, and humidity. By adjusting the values ​​of each input parameter, the output power of the fuel cell can be obtained when each parameter takes different values, thereby comparing the operating efficiency of the fuel cell when each parameter takes different values, and finding the parameter value set with the highest operating efficiency to update the mapping table, obtain the most controllable parameters, realize self-optimization of the mapping table, further improve energy utilization and reduce energy consumption, and help to achieve efficient operation of the fuel cell system.

[0060] As an optional implementation, in the case where the value of the input parameter of the target power supply currently being adjusted is the value of the target parameter, the values ​​of each input parameter of the target power supply are adjusted in sequence based on each parameter value in the target parameter value set, including: adjusting the value of the target input parameter of the target power supply from the target parameter value in the target parameter set to a target adjustment parameter value; obtaining the efficiency of the target power supply through the value of the adjusted input parameter, including: determining other parameter values ​​in the target parameter set except the target parameter value and the target adjustment parameter value as a first adjustment parameter value set; obtaining the power of the target power supply when the values ​​of each input parameter of the target power supply are the parameter values ​​in the first adjustment parameter value set, to obtain a first adjustment power; and determining the ratio of the target adjustment parameter value to the first adjustment power as a first adjustment efficiency value.

[0061] The above target parameter value may be the value of the target parameter in the target parameter set, and the above target adjustment parameter value may be the value after the target parameter is adjusted. By adjusting the value of the target parameter, the output power of the fuel cell under different target parameter values ​​can be obtained; the above first adjustment parameter value set is a set of target adjustment parameters in the target parameter set, and only the value of the target parameter is adjusted as the target adjustment parameter. By only changing the value of the single variable of the target parameter, the output power of the fuel cell under different target parameter values ​​is obtained, and the operating efficiency of the fuel cell under different conditions is compared. For example, the target parameter is hydrogen content, the target parameter value in the target parameter set is 50mol, and the target parameter set is (oxygen 40mol, hydrogen 50mol, membrane water content 70%, temperature 60℃, humidity 40%). At this time, the output power of the fuel cell is 200kW, and when the target adjustment parameter value is 55mol, the first adjustment parameter value set is (oxygen 40mol, hydrogen 55mol, membrane water content 70%, temperature 60℃, humidity 40%), and the output power of the fuel cell is 250kW. The operating efficiency of the fuel cell under the two parameter conditions is determined respectively.

[0062] As an optional implementation, when the efficiency value of the target power supply increases, the adjusted parameter value and the corresponding power are recorded in the mapping table, including: when the values ​​of each input parameter of the target power supply are set to the parameter values ​​in the target parameter value set and the power of the target power supply is a first power, the ratio of the first power to the target parameter value in the target parameter value set is determined as a first efficiency value; when the first adjusted efficiency value is greater than the first efficiency value, the first adjusted power and the first adjustment parameter set are recorded in the mapping table.

[0063] The above-mentioned first efficiency value is the operating efficiency of the fuel cell under the target parameter set, and the above-mentioned first adjusted efficiency value is the operating efficiency of the fuel cell under the first adjusted parameter value set. The first efficiency value is compared with the first adjusted efficiency value. When the first adjusted efficiency value is greater than the first efficiency value, the first adjusted power and the first adjustment parameter set are recorded in the mapping table. Otherwise, the adjusted target parameter value is taken as the value in the target parameter set.

[0064] As an optional implementation, in the case that what is currently being adjusted is the value of the first input parameter among the input parameters of the target power supply, the first input parameter is a parameter other than the target input parameter, and the values ​​of each input parameter of the target power supply are adjusted in sequence based on each parameter value in the target parameter value set, and it also includes: adjusting the value of the first input parameter of the target power supply from the first parameter value in the target parameter set to a first adjustment parameter value; obtaining the efficiency of the target power supply through the value of the adjusted input parameter, including: determining the parameter values ​​in the target parameter set other than the first parameter value and the first adjustment parameter value as a second adjustment parameter value set; obtaining a second adjusted power, wherein the second adjusted power is the power of the target power supply when the values ​​of each input parameter are the second adjustment parameter value set; and determining the ratio of the target parameter value in the target parameter value set to the second adjustment power as a second adjustment efficiency value.

[0065] As an optional implementation, when the efficiency value of the target power supply increases, the adjusted parameter value and the corresponding power are recorded in the mapping table, including: when the values ​​of each input parameter of the target power supply are set to the parameter values ​​in the target parameter value set and the power of the target power supply is a first power, the ratio of the first power to the target parameter value in the target parameter value set is determined as a first efficiency value; when the second adjusted efficiency value is greater than the first efficiency value, the third power and the second adjusted parameter set are recorded in the mapping table.

[0066] The first input parameter is a parameter other than the target input parameter. For example, the parameters affecting the output power of the proton exchange membrane fuel cell (PEMFC) include oxygen content, hydrogen content, membrane water content, temperature, and humidity. When the target input parameter is hydrogen content, the first input parameter can be any one of oxygen content, hydrogen content, membrane water content, temperature, and humidity. The specific adjustment method of the first input parameter can refer to the above embodiment.
