101. a target cell temperature of the fuel cell is acquired.
In the embodiment of the present application, the electronic device may include at least one fuel cell. The electronic device can monitor the battery temperature of the fuel battery in real time, and specifically, the electronic device can include a temperature sensor for detecting the temperature of the fuel battery, so that the target battery temperature of the fuel battery can be obtained.

In one possible example, the step 102 of determining the target operating parameter of the fuel cell according to the target cell temperature may be implemented as follows:
and determining a target working parameter corresponding to the target battery temperature according to a preset mapping relation between the battery temperature and the working parameter of the fuel battery.
Specifically, the electronic device may pre-store a mapping relationship between a preset battery temperature and a working parameter of the fuel cell, and then determine a target working parameter corresponding to the target battery temperature according to the mapping relationship, so that the working parameter suitable for the battery temperature may be obtained, which is beneficial to improving the working efficiency of the fuel cell.
In one possible example, the step 102 of determining the target operating parameter of the fuel cell according to the target cell temperature may include the steps of:
21. acquiring a target working mode of the fuel cell;
22. acquiring a target mapping relation corresponding to the target working mode, wherein the target mapping relation is a mapping relation between the battery temperature and working parameters of the fuel battery;
23. and determining the target working parameters corresponding to the target battery temperature according to the target mapping relation.
Wherein, the target working mode may be at least one of the following: a charging mode (e.g., a fast charging mode, a normal charging mode, etc.), a discharging mode, etc., which are not limited herein. The electronic device may pre-store a mapping relationship between the battery temperature and the operating parameter of the fuel cell in different operating modes, and in a specific implementation, the electronic device may obtain a target operating mode of the fuel cell, and further obtain a target mapping relationship corresponding to the target operating mode, where the target mapping relationship is also a mapping relationship between the battery temperature and the operating parameter of the fuel cell, and further determine the target operating parameter corresponding to the target battery temperature according to the target mapping relationship.
103. And controlling the fuel cell to work at the target working parameter.
The electronic device may include a Power Manager Service (PMS), and the electronic device may control the fuel cell to operate at the target operating parameter through the PMS. When the electronic equipment comprises a plurality of fuel cells, the mapping relation between foreground application and the number of the fuel cells can be stored in the electronic equipment in advance, and then the number of the target fuel cells corresponding to the foreground application can be determined, and the fuel cells corresponding to the number of the target fuel cells are controlled to work according to the target working parameters. In the concrete implementation, the influence on the battery temperature of the electronic equipment is different during charging and discharging, and the output power of the fuel battery is controlled by detecting the battery temperature of the fuel battery of the electronic equipment in real time, so that the battery temperature of the electronic equipment is adjusted, and the speed of chemical reaction of fuel in the fuel battery is controlled correspondingly according to the requirement.
In a possible example, between the step 102 and the step 103, the following steps may be further included:
a1, acquiring a target foreground application of the electronic equipment;
a2, determining the working parameter range of the fuel cell corresponding to the target foreground application;
a3, when the target working parameter is in the working parameter range, executing the step of controlling the fuel cell to work at the target working parameter.
The power consumption conditions of different applications that need to be provided are different, and therefore, for different applications, in the specific implementation that the fuel cell corresponding to the application is preset for each application, the electronic device may obtain the target foreground application, and may further determine the working parameter range of the fuel cell corresponding to the target foreground application, and when the target working parameter is within the target parameter range, step 103 may be executed.
Further, in one possible example, the following steps may also be included:
b1, when the target working parameter is not in the working parameter range, determining a target deviation value between the target working parameter and the working parameter range;
b2, determining a target adjustment factor corresponding to the target deviation value;
b3, adjusting the target working parameters according to the target adjustment factors;
and B4, controlling the fuel cell to work according to the adjusted target working parameter.
When the target operating parameter is not within the target operating parameter, the electronic device may determine a target deviation value between the target operating parameter and the operating parameter range, and specifically, a difference value between any value in the operating parameter range and the target operating parameter may be used as the target deviation value between the target operating parameter and the operating parameter range, for example, the any value may be a mean value, or a minimum value of the operating parameter range. The mapping relation between the deviation value and the adjusting factor can be stored in the electronic device in advance, and then a target adjusting factor corresponding to the target deviation value can be determined according to the mapping relation, a target working parameter is adjusted according to the target adjusting factor, namely the adjusted target working parameter is the target working parameter, or the adjusted target working parameter is the target working parameter plus the target adjusting factor, and finally, the fuel cell can be controlled to work according to the adjusted target working parameter.
In one possible example, when the fuel cell is in the charging mode, after the step 103, the following steps may be further included:
c1, acquiring the current battery temperature of the fuel battery;
c2, when the current battery temperature is higher than a first preset temperature, acquiring a target environment temperature;
c3, determining a target difference between the current battery temperature and the target ambient temperature;
c4, determining a target adjusting coefficient for adjusting the target working parameter according to the target difference;
c5, adjusting the target working parameters according to the target adjusting coefficient;
c6, controlling the fuel cell to work according to the adjusted target working parameter.
In the embodiment of the present application, the preset temperature may be set by a user or default by a system, when the fuel cell is in a charging mode, the current cell temperature of the fuel cell may be obtained, when the current cell temperature is higher than a first preset temperature, the target ambient temperature may be obtained, a target difference between the current cell temperature and the target ambient temperature is determined, and then a target adjustment coefficient for adjusting the target operating parameter is determined according to the target difference, specifically, a mapping relationship between the difference and the adjustment coefficient may be preset, and then a target adjustment coefficient corresponding to the target difference may be determined according to the mapping relationship, the target operating parameter is adjusted according to the target adjustment coefficient, and the fuel cell is controlled to operate according to the adjusted target operating parameter, so that, in the operating process of the fuel cell, it is considered that the battery temperature is too high and may be caused by the external ambient temperature, therefore, the operating parameters of the fuel cell can be adjusted based on the ambient temperature, and the operating performance of the fuel cell can be improved.
For example, when the electronic device is in the charging mode, the ambient temperature and the battery temperature may be collected, and the charging output power of the fuel cell may be dynamically adjusted according to the ambient temperature and the battery temperature, and if the battery temperature is higher, the output power of the fuel cell may be reduced, and if the temperature is lower, the output power of the fuel cell may be increased. Thus, the output power of the fuel cell is dynamically adjusted, and the utilization rate of the fuel cell can be improved.
In a possible example, between the step 102 and the step 103, the following steps may be further included:
d1, acquiring the residual capacity of the electronic equipment;
d2, when the residual electric quantity is lower than a preset electric quantity, acquiring M applications running in a background, wherein M is an integer larger than 1;
d3, selecting N applications belonging to a preset application list from the M applications, where N is a positive integer less than or equal to M, closing the N applications, and executing the step 103.
The preset electric quantity can be set by a user or defaulted by a system, and the preset application list can comprise at least one application. In specific implementation, the electronic device may obtain a remaining power of the electronic device, and when the remaining power is lower than a preset power, M applications running in a background may be obtained, where M is an integer greater than 1, N applications belonging to a preset application list are selected from the M applications, where N is a positive integer less than or equal to M, the N applications are closed, and step 103 is executed again, so that a system running environment may be optimized, power consumption of the device may be reduced, and user experience may be improved.
In a possible example, when the target battery temperature is lower than a second preset temperature and the target operating parameter exceeds a preset operating parameter, between the step 102 and the step 103, the following steps may be further included:
e1, acquiring a target fingerprint image;
e2, matching the target fingerprint image with a preset fingerprint template;
e3, when the matching between the target fingerprint image and the preset fingerprint template is successful, executing step 103.
The second preset temperature and the preset working parameters can be set by a user or defaulted by a system, and a preset fingerprint template can be stored in the electronic equipment in advance. The electronic device may execute step 103 when the target fingerprint image is successfully matched with the preset fingerprint template, otherwise, when the target fingerprint image is unsuccessfully matched with the preset fingerprint template, the electronic device may prompt the user that the fingerprint unlocking is unsuccessfully performed, or prompt the user to perform fingerprint input again. In the specific implementation, the performance of the fuel cell is not ideal under the low-temperature condition, so that if the fuel cell needs to be regulated forcibly, the fuel cell may be damaged to a certain extent, and in the emergency condition, a user can forcibly make the fuel cell work through fingerprint verification.
In one possible example, the step E2 of matching the target fingerprint image with the preset fingerprint template may include the following steps:
e21, carrying out image segmentation on the target fingerprint image to obtain a target fingerprint area image;
e22, analyzing the distribution of the characteristic points of the target fingerprint area image;
e23, performing circular image interception on the target fingerprint area image according to M different circle centers to obtain M circular fingerprint area images, wherein M is an integer greater than 3;
e24, selecting a target circular fingerprint area image from the M circular fingerprint area images, wherein the number of the characteristic points contained in the target circular fingerprint area image is larger than that of other circular fingerprint area images in the M circular fingerprint area images;
e25, dividing the target circular fingerprint area image to obtain N circular rings, wherein the widths of the N circular rings are the same;
e26, starting from the circular ring with the smallest radius in the N circular rings, sequentially matching the N circular rings with the preset fingerprint template for feature points, and accumulating the matching values of the matched circular rings;
e27, when the accumulated matching value is larger than the target fingerprint identification threshold value, immediately stopping the characteristic point matching, and outputting a prompt message of successful fingerprint identification.
Wherein, the electronic device can perform image segmentation on a target fingerprint image to obtain a target fingerprint area image, further analyze the feature point distribution of the target fingerprint area image, perform circular image interception on the target fingerprint area image according to M different circle centers to obtain M circular fingerprint area images, M is an integer greater than 3, select the target circular fingerprint area image from the M circular fingerprint area images, the number of the feature points contained in the target circular fingerprint area image is greater than that of other circular fingerprint area images in the M circular fingerprint area images, divide the target circular fingerprint area image to obtain N circular rings, the ring widths of the N circular rings are the same, perform feature point matching on the N circular rings with a preset fingerprint template in sequence from the circular ring with the smallest radius among the N circular rings, and accumulate the matching values of the matched circular rings, thus, in the fingerprint identification process, the feature points of different positions or different fingerprints can be used for matching, namely, the whole fingerprint image is sampled, and the sampling can cover the whole fingerprint area, so that corresponding representative features can be found from each area for matching, when the accumulated matching value is greater than the target fingerprint identification threshold value, the feature point matching is immediately stopped, and the prompt message of the fingerprint identification success is output, therefore, the fingerprint identification can be quickly and accurately identified.
