Abstract
Description
Technical Field
[0001] This application relates to the field of batteries, specifically to a method and apparatus for switching parameters in a solid oxide battery, an electronic device, and a computer-readable storage medium. Background Technology
[0002] In existing applications of solid oxide fuel cells (SOFCs), the single-step switching strategy has become the mainstream operation and regulation method due to its simple control logic and strong hardware adaptability, and is widely used in various scenarios such as distributed power generation and portable power. However, this strategy is significantly contradictory to the operating characteristics of SOFCs themselves, leading to many unavoidable problems in actual operation. These problems not only affect the operational stability of the battery system but also accelerate battery degradation and limit its dynamic response performance, severely hindering the industrialization and long-term promotion of SOFC technology.
[0003] One of the core contradictions stems from the severe mismatch between the chemical reaction rate of SOFCs and the response speed of the gas supply system. The electrochemical reactions inside SOFCs are millisecond-level instantaneous processes. The catalytic reaction of fuel and oxidant on the electrode surface and the migration of ions in the electrolyte all require a continuous and stable supply of substances to ensure the efficient advancement of the reaction. However, in actual gas supply systems, there is an unavoidable time delay from the issuance of flow commands and valve adjustment to the transfer of fuel / oxidant through pipelines to the electrode reaction zone.
[0004] When a single-step switching strategy is adopted, the gas supply system will make a one-time, leapfrog parameter adjustment according to the load demand. The superposition of this instantaneous adjustment and the gas supply delay can easily lead to a disconnect between fuel supply and reaction demand, causing fuel shortage problems. Summary of the Invention
[0005] In view of this, it is necessary to provide a method and apparatus for switching parameters of a solid oxide battery, an electronic device and a computer-readable storage medium, so as to achieve the technical effect of reducing the possibility of fuel depletion during parameter switching of a solid oxide battery.
[0006] To address the aforementioned technical problems, in a first aspect, this application provides a method for switching parameters in a solid oxide battery, comprising: The initial power and target power of the solid oxide battery are obtained, and the auxiliary power is determined based on the initial power and the target power. The auxiliary power is greater than the target power and greater than the initial power. The auxiliary power is the solid oxide battery power with the shortest target power increase time. The target power increase time is the time required for the power of the solid oxide battery to increase from the initial power to the target power. The input parameters of the solid oxide battery are switched from initial input parameters to auxiliary input parameters, wherein the initial input parameters are the input parameters corresponding to the initial power, and the auxiliary input parameters are the input parameters corresponding to the auxiliary power; When the actual power of the solid oxide battery reaches the target power, the input parameters of the solid oxide battery are switched from the auxiliary input parameters to the target input parameters, where the target input parameters are the input parameters corresponding to the target power.
[0007] In one possible embodiment, determining the auxiliary power based on the initial power and the target power includes: Obtain a sample curve set, which includes multiple power-time curves, each power-time curve corresponding to a unique endpoint power; Obtain the target power increase duration corresponding to each of the power-time curves, and take the power-time curve with the smallest target power increase duration as the target power-time curve; The endpoint power corresponding to the target power-time curve is obtained as the auxiliary power.
[0008] In one possible embodiment, the step of the solid oxide battery reaching the target power includes: The actual power of the solid oxide battery is detected in real time, and the power difference between the actual power and the target power is calculated. Determine whether the power difference is less than a set power difference threshold; If the power difference is less than the set power difference threshold, it is determined that the actual power of the solid oxide battery has reached the target power.
[0009] In one possible embodiment, before switching the input parameters of the solid oxide battery from the initial input parameters to the auxiliary input parameters, the method further includes: Multiple parameter switching tests were conducted on the solid oxide battery to obtain multiple test parameter pairs, which included corresponding parameter switching times and hydrogen mole fractions. The target switching time is determined based on the hydrogen mole fraction. The step of switching the input parameters of the solid oxide battery from initial input parameters to auxiliary input parameters includes: At the target switching time, the input parameters of the solid oxide battery are switched from the initial input parameters to auxiliary input parameters.
[0010] In one possible embodiment, determining the target switching time based on the hydrogen mole fraction includes: The parameter switching time at which the hydrogen mole fraction is zero is determined as the target switching time.
[0011] In one possible embodiment, the parameter switching time at which the hydrogen mole fraction is determined to be zero is taken as the target switching time, including: The minimum value among the parameter switching times where the hydrogen mole fraction is zero is determined as the target switching time.
[0012] In one possible embodiment, the input parameters include at least fuel utilization rate, excess air ratio, bypass valve opening degree, and current.
[0013] Secondly, this application provides a solid oxide battery parameter switching device, comprising: An auxiliary power determination module is used to obtain the initial power and target power of the solid oxide battery, and determine the auxiliary power based on the initial power and the target power. The auxiliary power is greater than the target power and greater than the initial power. The auxiliary power is the solid oxide battery power with the shortest target power increase time. The target power increase time is the time required for the power of the solid oxide battery to increase from the initial power to the target power. A parameter switching module is used to switch the input parameters of the solid oxide battery from initial input parameters to auxiliary input parameters, wherein the initial input parameters are the input parameters corresponding to the initial power, and the auxiliary input parameters are the input parameters corresponding to the auxiliary power; The power monitoring module is used to monitor the actual power of the solid oxide battery. The parameter switching module is also used to switch the input parameters of the solid oxide battery from the auxiliary input parameters to the target input parameters when the actual power of the solid oxide battery reaches the target power.

[0014] Thirdly, this application also provides an electronic device, including a memory and a processor, wherein, The memory is used to store programs; The processor, coupled to the memory, is used to execute the program stored in the memory to implement the steps in the solid oxide battery parameter switching method described in any of the above implementations.
[0015] Fourthly, this application also provides a computer-readable storage medium for storing a computer-readable program or instructions, which, when executed by a processor, can implement the steps in the solid oxide battery parameter switching method described in any of the above implementations.
[0016] The beneficial effects of this application are: Compared with related technologies, the solid oxide battery parameter switching method, apparatus, electronic device, and computer-readable storage medium provided in this application, because the auxiliary power is greater than the target power, the fuel flow rate in the auxiliary input parameter is greater than the fuel flow rate corresponding to the target input parameter. The higher fuel flow rate can build a sufficient fuel supply environment in advance, eliminate the impact of response delay in fuel transmission and diffusion, and achieve the technical effect of reducing the possibility of fuel shortage during solid oxide battery parameter switching. At the same time, the auxiliary power is set to the power with the shortest target power increase time, which can increase the power of the solid oxide battery to the target power more quickly while ensuring sufficient fuel. When the actual power reaches the target power, the battery reaction demand has stabilized at the level corresponding to the target power. The fuel flow rate in the target input parameter can accurately match the reaction demand at this time, and the input parameter is switched from the auxiliary input parameter to the target input parameter, which avoids the waste caused by continuously supplying too much fuel and maintains reaction stability.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

Therefore, a technical feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] This application provides a method and apparatus for switching parameters of a solid oxide battery, an electronic device, and a computer-readable storage medium, which are described below.
[0024] Please refer to Figure 1 The solid oxide battery parameter switching method provided in this application includes: Step S101: Obtain the initial power and target power of the solid oxide battery, and determine the auxiliary power based on the initial power and target power. The auxiliary power is greater than the target power, which is greater than the initial power.
[0025] In this step, the initial power is the power of the solid oxide battery before parameter switching, and the target power is the final power that the solid oxide battery needs to switch to.
[0026] For further details, please refer to Figure 2 Determining the auxiliary power based on the initial power and the target power specifically includes the following steps: Step S201: Obtain a sample curve set, which includes multiple power-time curves, each power-time curve corresponding to a unique endpoint power.
[0027] In this step, the power-time curve is a curve showing the change of power of a solid oxide battery over time, constructed from experimental data obtained by conducting parameter switching experiments on the solid oxide battery in advance.
[0028] Specifically, the power-time curve of the solid oxide battery corresponds one-to-one with the endpoint power during the experiment. The endpoint power is the final power during the parameter switching experiment. That is, each experimental process involves switching the initial power of the solid oxide battery to the endpoint power, monitoring the real-time power during the switching process, and finally constructing a power-time curve based on the real-time power and its sampling time. Each power-time curve corresponds to a unique endpoint power. For example, for endpoint powers A1, A2...A5, during the experiment, the initial power of the solid oxide battery is switched to the endpoint power A1, resulting in the power-time curve B1 for this process. Power-time curve B1 corresponds to the unique endpoint power A1. During the experiment, the initial power of the solid oxide battery is also switched to the endpoint power A2, resulting in the power-time curve B2 for this process. Power-time curve B2 corresponds to the unique endpoint power A2... and so on. During the experiment, the initial power of the solid oxide battery is switched to the endpoint power A5, resulting in the power-time curve B5 for this process. Power-time curve B5 corresponds to the unique endpoint power A5.
[0029] Step S202: Obtain the target power increase duration corresponding to each power-time curve, and take the power-time curve with the smallest target power increase duration as the target power-time curve.
[0030] The target power boost time is the time required for the solid oxide battery's power to increase from the initial power to the target power. Based on this, in this step, the initial power and target power are substituted into each power-time curve to obtain the initial time corresponding to the initial power and the target time corresponding to the target power in the power-time curve. The time interval between the initial time and the target time is the target power boost time corresponding to that power-time curve. Each power-time curve corresponds to one target power boost time.
[0031] The target power-time curve is defined as the power-time curve with the minimum target power increase duration. Specifically, this involves comparing the target power increase durations corresponding to all power-time curves in the sample curve set to obtain the minimum target power increase duration. The target power-time curve corresponds to this minimum target power increase duration.
[0032] Step S203: Obtain the endpoint power corresponding to the target power-time curve as the auxiliary power.
[0033] Step S102: Switch the input parameters of the solid oxide battery from the initial input parameters to the auxiliary input parameters.
[0034] In this step, the initial input parameters are the input parameters corresponding to the initial power, and the auxiliary input parameters are the input parameters corresponding to the auxiliary power.
[0035] The input parameters include at least fuel utilization rate, excess air ratio, bypass valve opening degree, and current.
[0036] Step S103: When the actual power of the solid oxide battery reaches the target power, switch the input parameters of the solid oxide battery from auxiliary input parameters to target input parameters.
[0037] The target input parameters are the input parameters corresponding to the target power.
[0038] Please refer to Figure 3 In this step, determining whether the actual power of the solid oxide battery reaches the target power specifically includes: Step S301: Real-time detection of the actual power of the solid oxide battery, and calculation of the power difference between the actual power and the target power.
[0039] In this step, multiple sampling times are set based on a set time step. The actual power of the solid oxide battery is measured at each sampling time. After each measurement of the actual power, the power difference between the actual power and the target power is calculated.
[0040] Step S302: Determine whether the power difference is less than the set power difference threshold. If yes, proceed to step S303; otherwise, proceed to step S301.
[0041] In this step, the power difference threshold is set as a pre-defined power difference judgment standard. Its core function is to serve as a benchmark for judging power changes. This threshold needs to be set in combination with battery type, operating conditions and experimental requirements.
[0042] Step S303: Determine whether the actual power of the solid oxide battery reaches the target power.
[0043] Compared with related technologies, the solid oxide battery parameter switching method provided in this application, because the auxiliary power is greater than the target power, has a higher fuel flow rate in the auxiliary input parameters than the fuel flow rate corresponding to the target input parameters. This higher fuel flow rate allows for the early establishment of a sufficient fuel supply environment, eliminating the impact of response delays in fuel transport and diffusion, and reducing the possibility of fuel shortage during solid oxide battery parameter switching. Simultaneously, setting the auxiliary power to the power with the shortest target power increase time allows for faster power increase of the solid oxide battery to the target power while ensuring sufficient fuel. When the actual power reaches the target power, the battery reaction demand has stabilized at the level corresponding to the target power. The fuel flow rate in the target input parameters can then accurately match the reaction demand, switching the input parameters from auxiliary input parameters to target input parameters. This avoids waste caused by continuously supplying excessively high fuel levels while maintaining reaction stability.
[0044] Please refer to Figure 4 The solid oxide battery parameter switching method provided in this application includes: Step S401: Obtain the initial power and target power of the solid oxide battery, and determine the auxiliary power based on the initial power and target power. The auxiliary power is greater than the target power, which is greater than the initial power.
[0045] Step S402: Determine the target switching time.
[0046] In this step, the switching time is the initial time determined by the power switching requirement, and the time point at which the switching occurs. For example, if the initial time for power switching is determined to be 9:00, and the parameter switching is scheduled to begin at 9:02, then the corresponding switching time is 2 seconds.
[0047] In this step, the optimal switching time is obtained by conducting parameter switching experiments on the solid oxide battery beforehand, and this is taken as the target switching time. Please refer to [link / reference needed]. Figure 5 Determining the target switching time specifically includes the following steps: Step S501: Perform multiple parameter switching tests on the solid oxide battery to obtain multiple test parameter pairs, including the corresponding parameter switching time and hydrogen mole fraction.
[0048] In this step, the current switching time tc and the time interval dt are set. Parameter switching experiments are conducted based on the switching times tc, tc+dt, tc+2×dt...tc+N×dt. During each parameter switching experiment, the hydrogen mole fraction of the solid oxide battery is monitored, and the parameter switching time and hydrogen mole fraction are matched one-to-one to form experimental parameter pairs.
[0049] Step S502: Determine the target switching time based on the hydrogen mole fraction.
[0050] In this step, the parameter switching time where the hydrogen mole fraction is zero is determined as the target switching time. That is, multiple experimental parameter pairs with a hydrogen mole fraction of zero are obtained, and the parameter switching times of these pairs are used as the target switching time.
[0051] Furthermore, if there are multiple experimental parameter pairs with a hydrogen mole fraction of zero, obtain the switching time of all parameters in these experimental parameter pairs with a hydrogen mole fraction of zero, and take the minimum parameter switching time as the target switching time.
[0052] Step S403: At the target switching time, switch the input parameters of the solid oxide battery from the initial input parameters to the auxiliary input parameters.
[0053] Step S404: When the actual power of the solid oxide battery reaches the target power, switch the input parameters of the solid oxide battery from auxiliary input parameters to target input parameters.
[0054] It is understood that steps S401, S403, and S404 in this embodiment are largely the same as steps S101 to S103 in the previous embodiment. For details, please refer to the specific description in the previous embodiment, which will not be repeated here.
[0055] Compared with related technologies, the solid oxide battery parameter switching method provided in this application retains all the technical effects of the aforementioned embodiments, and also determines the target switching time by the hydrogen mole fraction. At the target switching time, the input parameters of the solid oxide battery are switched from the initial input parameters to the auxiliary input parameters, which can further reduce the possibility of fuel depletion during solid oxide battery parameter switching.
