Description

Charging control method and electronic equipment

Technical Field

The present application relates to the field of terminal devices, and in particular, to a charging control method and an electronic device.

Background

Currently, charging integrated circuits (integrated circuit, ICs) typically operate at a fixed frequency while an electronic device is being charged. However, during charging, a constant charging frequency may cause a decrease in charging efficiency due to a change in the charging scene.

Disclosure of Invention

The application provides a charging control method and electronic equipment. In the method, the electronic device can dynamically adjust the charging frequency according to scene changes.

In a first aspect, the present application provides a charge control method. The method comprises the following steps: and in the process of charging the electronic equipment, acquiring equipment parameters of the electronic equipment, wherein the equipment parameters are used for indicating the charging state of the charging chip. Based on the first database information, a first frequency corresponding to a maximum efficiency value that matches the device parameter is determined. Based on the second database information, it is detected whether the first frequency matches a vibration frequency of at least one module being invoked by the electronic device. If the first frequency is not matched with the vibration frequency of at least one module, the frequency of the charging chip is updated to the first frequency. Therefore, the application can obtain the frequency corresponding to the maximum efficiency value based on the change of the equipment parameters under different scenes by presetting the corresponding relation among the efficiency value, the equipment parameters and the working frequency. And the application compares the selected frequency with the vibration frequency of at least one module being called, so that the working frequency of the charging IC avoids the vibration frequency of the module being called, thereby avoiding causing resonance of other modules. Therefore, the inter-module interference is effectively reduced while the charging efficiency is ensured.

Exemplary device parameters include: at least one of current, voltage, temperature (i.e., the temperature of the charging IC).

By way of example, the vibration frequency of a module may be understood to be that if the vibration frequency of other modules coincides with the vibration frequency of the module, the module may be caused to resonate.

The vibration frequency of the module may be a constant value or a range, and the application is not limited.

For example, detecting whether the first frequency matches the vibration frequency of the module may be detecting whether the first frequency falls within the vibration frequency range of the module, or detecting whether the first frequency coincides with the vibration frequency range of the module.

In one possible implementation, the method further includes: if the first frequency is matched with the vibration frequency of the at least one module and the current frequency of the charging chip is not matched with the vibration frequency of the at least one module, determining that the frequency of the charging chip is kept at the current frequency. In this way, the application can preferentially reduce the module resonance problem caused by charging, that is, when the operating frequency corresponding to the selected maximum efficiency point possibly causes the module resonance, the current frequency which does not cause the module resonance can be selected.

In one possible implementation, the method further includes: if the first frequency is matched with the vibration frequency of at least one module, and the current frequency of the charging chip is matched with the vibration frequency of at least one module, searching a second frequency which is not the first frequency and corresponds to the maximum efficiency value matched with the equipment parameter from the first database information. Based on the second database information, it is detected whether the second frequency matches a vibration frequency of at least one module being invoked by the electronic device. And if the second frequency is not matched with the vibration frequency of at least one module, updating the frequency of the charging chip to the second frequency. Thus, if the selected optimal frequency (i.e., the frequency corresponding to the maximum efficiency point) and the current frequency may both cause module resonance, the electronic device may select the frequency corresponding to the suboptimal efficiency, and select the frequency as the frequency of the charging IC if it is detected that the frequency does not cause inter-module resonance. Thus avoiding the problem of module resonance caused by charging while ensuring the charging efficiency as much as possible.

In one possible implementation, if the first frequency does not match the vibration frequency of the at least one module, updating the frequency of the charging chip to the first frequency further includes: obtaining an efficiency difference value between the maximum efficiency value and a current efficiency value corresponding to the current frequency of the charging chip; if the efficiency difference is greater than or equal to a preset value and the first frequency is not matched with the vibration frequency of at least one module, updating the frequency of the charging chip to the first frequency; if the efficiency difference is smaller than the preset value and the current frequency is not matched with the vibration frequency of at least one module, the frequency of the charging chip is kept at the current frequency. In this way, the electronic device may obtain efficiency benefits between the new frequency and the current frequency based on the efficiency difference between the current frequency and the selected frequency. And determines whether a new frequency needs to be switched based on efficiency benefits. Wherein if efficiency benefits are low, the new frequency may not be switched, but the current frequency may be maintained.

In one possible implementation, detecting whether the first frequency matches a vibration frequency of at least one module being invoked by the electronic device based on the second database information includes: acquiring at least one application running on the electronic device; at least one module invoked by the at least one application is determined based on the third database information. Thus, the electronic equipment can acquire the modules called by the application, so that the vibration frequency corresponding to each module can be accurately acquired. And then when the charging frequency of the charging IC is selected, the vibration frequency of the calling module can be avoided, so that module resonance caused by charging is avoided.

In a second aspect, the present application provides an electronic device comprising: one or more processors, memory; and one or more computer programs, wherein the one or more computer programs are stored on the memory, which when executed by the one or more processors, cause the electronic device to perform the steps of: acquiring equipment parameters of the electronic equipment in the process of charging the electronic equipment, wherein the equipment parameters are used for indicating the charging state of a charging chip; determining a first frequency corresponding to a maximum efficiency value matched with the equipment parameter based on the first database information; detecting whether the first frequency matches a vibration frequency of at least one module being invoked by the electronic device based on the second database information; if the first frequency is not matched with the vibration frequency of at least one module, the frequency of the charging chip is updated to the first frequency.

In one possible implementation, the computer program, when executed by one or more processors, causes the electronic device to perform the steps of: if the first frequency is matched with the vibration frequency of the at least one module and the current frequency of the charging chip is not matched with the vibration frequency of the at least one module, determining that the frequency of the charging chip is kept at the current frequency.

In one possible implementation, the computer program, when executed by one or more processors, causes the electronic device to perform the steps of: if the first frequency is matched with the vibration frequency of at least one module, and the current frequency of the charging chip is matched with the vibration frequency of at least one module, searching a second frequency which is not the first frequency and corresponds to the maximum efficiency value matched with the equipment parameter from the first database information; detecting whether the second frequency matches a vibration frequency of at least one module being invoked by the electronic device based on the second database information; and if the second frequency is not matched with the vibration frequency of at least one module, updating the frequency of the charging chip to the second frequency.

In one possible implementation, the computer program, when executed by one or more processors, causes the electronic device to perform the steps of: obtaining an efficiency difference value between the maximum efficiency value and a current efficiency value corresponding to the current frequency of the charging chip; if the efficiency difference is greater than or equal to a preset value and the first frequency is not matched with the vibration frequency of at least one module, updating the frequency of the charging chip to the first frequency; if the efficiency difference is smaller than the preset value and the current frequency is not matched with the vibration frequency of at least one module, the frequency of the charging chip is kept at the current frequency.

The following is a brief description of the background art that may be involved:

1) Charging disturbance

Fig. 4 is a schematic diagram illustrating the cause of the charging interference, and referring to fig. 4 specifically, through laser vibration measurement analysis, when the terminal device is charged (the configuration frequency XHz (hz)), the piezoelectric effect of the alternating voltage will cause the capacitance vibration of the charging IC, that is, drive the printed circuit board (Printed Circuit Board, PCB) to vibrate at the corresponding frequency. Wherein, the mechanical vibration of the PCB is concentrated around 2XHz times the frequency of the charging IC. The vibration frequency coincides with the high-frequency resonance point of the gyroscope device, so that the internal resonance of the gyroscope is caused, and the problem of large single-side noise is further caused. Since the frequency of the gyroscope cannot be changed and is distributed in a certain range, resonance is inevitably present.

2) Influence of frequency and loss

Illustratively, the conduction loss, the driving loss, the switching loss and the capacitance loss are different at different frequencies of different currents in the charging process. Table 1 shows the loss effects at different frequencies as exemplified:

TABLE 1

As shown in table 1, the higher the frequency of the charging IC, the lower the conduction loss, the higher the driving loss, the higher the switching loss, and the lower the capacitance loss. The lower the frequency of the charging IC, the higher the conduction loss, the lower the drive loss, the lower the switching loss, and the higher the capacitance loss.

Switching lossThe calculation formula of (2) is shown as formula (1):

（1）

the factor of 0.5 is because the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) turn-on curve is considered to be approximately linear, which translates into an area power of 0.5.Vin is the input voltage and Io is the output current. tr and tf are rising time and falling time of the MOS transistor, and refer to the time when the drain-source voltage drops from 90% to 10% and the drain-source voltage rises from 10% to 90%, respectively.Is the switching frequency.

Drive lossThe calculation formula of (may also be referred to as gate drive loss) is shown as formula (2):

（2）

wherein n represents the number of MOS transistors (when the MOS transistors are identical in type selection),representing the switching frequency. />Is the input voltage. Qg is the gate power.The gate drive loss mainly occurs on the power control chip, not on the MOS transistor, but the size of the gate drive loss is related to the parameters of the MOS transistor.

Conduction lossThe calculation formula of (may also be referred to as gate drive loss) is shown as formula (3):

（3）

wherein, thereinFor load current +.>On-resistance of switching tube with unit width, +.>For the total width of the switching tube,is a constant related to the topology structure and is used for measuring the contribution of the on-resistance of the switching tube to the loss in one charge-discharge period. / >Represents the total number of the switching tubes, T represents the charge-discharge period, < ->Representing the charging period>Represents the discharge period>Switch tube representing conduction in charging periodCount (n)/(l)>Representing the number of switching tubes that are turned on during the discharge period.

The application provides a charging control method, which can be used for determining the optimal frequency after carrying out frequency selection, switching and decoupling on a charging IC after detecting information such as user scene, temperature, current, voltage and the like in real time based on a real user scene, so that the charging efficiency is improved, and meanwhile, the interference on other devices in electronic equipment is avoided as much as possible.

Fig. 5 is a flow chart illustrating an exemplary charge control method, please refer to fig. 5, which specifically includes, but is not limited to, the following steps:

s501, establishing a database matrix.

Illustratively, in the embodiment of the present application, the database matrix (may also be referred to as database information or correspondence information, etc., which is not limited by the present application) includes a first database matrix and a second database matrix. The first database matrix is used to indicate the correspondence among the frequency (i.e. the frequency of the charging IC, which may also be understood as the operating frequency of the charging IC, and will not be repeated below), the load current, the efficiency, the voltage and the temperature. It should be noted that, in the embodiment of the present application, only the above-mentioned several corresponding relations are taken as examples for explanation, and in practical application, an operator may set more or less parameters and corresponding relations according to scene requirements, so the present application is not limited.

The second database matrix is used for indicating the vibration frequency corresponding to each module or device of the electronic equipment. And may be understood as frequencies that may cause the module or device to resonate.

For example, for a first database, an operator may obtain corresponding efficiency and temperature values based on different frequencies, different currents and voltages.

For example, table 2 is an exemplary first database matrix, please refer to table 2:

TABLE 2

As shown in table 2, for example, using a frequency of 310khz, an operator charges an electronic device, controls the frequency of a charging IC to 310khz, and adjusts the current intensity. For example, the operator adjusts the amperage to 2A, and the operator obtains the temperature, efficiency, and voltage of the electronic device under test (i.e., frequency 310khz, current 2A). The specific acquisition mode can be acquisition through a tool, the acquisition mode can be according to actual requirements, and the application is not limited.

For example, an operator may obtain multiple test results in the same scenario, and write the average value into the first database matrix. An operator can sequentially adjust the current intensity of different gears under the gear with the frequency of 310khz so as to obtain corresponding parameter values such as temperature, voltage, efficiency and the like.

The operator may adjust the frequency of the charging IC, and sequentially obtain the efficiency, voltage, temperature, and other parameter values at different current levels according to the above manner. Specific results are shown with reference to Table 2 and will not be described here.

It should be noted that the frequency shift and the current shift shown in table 2 are only illustrative examples, and may be set according to actual requirements, and the present application is not limited thereto.

For example, for the second database matrix, the operator may obtain the vibration frequency of the relevant device of the electronic apparatus according to the device specification and the historical experience value, so as to obtain the second database matrix.

For example, table 3 is an exemplary second database matrix, please refer to table 3

TABLE 3 Table 3

/>

It should be noted that, in the embodiment of the present application, the modules that may be affected by charging, such as a radio frequency, a screen, a sensor, etc., are all schematically illustrated, and may include, for example, a vibration frequency corresponding to the audio module, which is not limited by the present application.

It should be further noted that the frequencies in table 2 are only illustrative examples, and the present application is not limited thereto. In some examples, the frequencies corresponding to the modules may also be a certain frequency range, for example, each frequency range ±5 in table 2, which is not limited by the present application.

In one possible implementation, the database matrix may further comprise a third database matrix. The third database matrix is used to indicate the modules invoked by the different applications. For example, the modules corresponding to the video application include, but are not limited to: screens (including TP, display screen, fingerprint, power supply, etc.), and the like, the present application is not limited.

In the embodiment of the application, the database matrix can be stored in the electronic equipment before delivery. Optionally, the operator may update the database matrix and push the database matrix to each electronic device through the cloud. The updating mode of the database matrix can be set according to actual requirements, and the application is not limited.

S502, acquiring equipment parameters during charging.

For example, as shown in fig. 6, during the charging process, the electronic device (specifically, may be a charging management module, which will not be described again below) detects that charging is occurring (i.e., detects an input current), and may periodically acquire a device parameter. Optionally, the period duration may be set according to actual requirements, which is not limited by the present application, for example, in the embodiment of the present application, the period duration is 5s, that is, the electronic device obtains the device parameter every 5 s. Alternatively, the present flow may be ended after the charging is ended.

In an embodiment of the present application, the device parameters include, but are not limited to: at least one of current, voltage, temperature (i.e., the temperature of the charging IC). For example, during charging of the mobile phone, the user opens the video application using the mobile phone and views the video through the video application. In the use process of a user, the electronic equipment can periodically acquire the current value, the voltage value and the temperature value of the electronic equipment. Alternatively, the parameter values obtained in each period may be the same or different, and the present application is not limited thereto. The manner in which the charging management module obtains the parameters of each device can be set according to actual requirements, and the application is not limited.

S503, determining the optimal frequency corresponding to the highest efficiency based on the database matrix and the equipment parameters.

For example, as shown in fig. 6, after the electronic device obtains the device parameter, the highest efficiency value corresponding to the device parameter may be determined based on the first database matrix in the database matrices.

For example, the electronic device obtains a current value of 2A. The electronic device obtains the efficiency value corresponding to the current 2A by querying a first database matrix (for example, as shown in table 2), which includes but is not limited to: a1%, B1%, C1%, D1%, E1%, F1%, G1%, H1%. The maximum value in the efficiency values, which is the maximum efficiency value corresponding to the current device parameter, is obtained by the electronic device, for example, A1%.

Still referring to fig. 6, the electronic device determines a corresponding optimal frequency based on the maximum efficiency value. For example, still taking the electronic device obtaining the maximum efficiency value of A1% as an example, the electronic device may determine the current 2A, and the frequency corresponding to the efficiency value of A1% is the optimal frequency, for example, 310khz is f1.

S504, judging whether to switch or not based on the efficiency difference value between the optimal frequency and the previous frequency.

For example, as shown in fig. 7, after the electronic device determines the optimal frequency, the electronic device may obtain an efficiency difference between the optimal frequency and the current frequency (i.e. the current frequency of the charging IC, which may also be understood as the target frequency determined by performing the process S502-S506 last time). The efficiency difference is the difference between the frequency and the maximum efficiency value corresponding to the device parameter (i.e. the maximum efficiency value determined in S503).

For example, the maximum efficiency value corresponding to the current 2A obtained this time is A1%, and the maximum efficiency value obtained last time is C1%. The electronic device may obtain a difference between the efficiency value of the last time and the efficiency value obtained this time.

S505, determining the target frequency based on the database matrix.

Illustratively, the charge management module may obtain the currently invoked application (this step may also be performed in S502, which is not limited by the present application).

The electronic device determines the relevant module invoked by the application based on the third database matrix. For example, the charge management module obtains that the current electronic device is running a video application, and may determine that relevant modules used by the video application include, but are not limited to, relevant modules of a screen (e.g., TP, etc.).

In one possible implementation, the charge management module may also send a request to the currently invoked application to request the application to feed back the module it invoked. The application is not limited.

As shown in fig. 8, after the charge management module obtains the modules invoked by the application, the vibration frequency corresponding to each module being invoked may be determined based on the second database matrix.

Referring to fig. 8, the charging management module may compare the current frequency and the optimal frequency determined in S504 with the vibration frequencies of the modules being invoked respectively to achieve decoupling of the frequencies, i.e. the selected target frequency may avoid the vibration frequencies of the modules being invoked to avoid causing resonance of other modules.

In one possible implementation, if the difference in efficiency between the optimal frequency and the current frequency is greater than or equal to a preset threshold (for example, 2%, which may be set according to actual requirements, the present application is not limited), it may be determined that the optimal frequency may be switched. In one example, if the current frequency matches the vibration frequency of the at least one module being invoked (i.e., the current frequency may cause resonance of the at least one module being invoked), and the optimal frequency does not match the vibration frequency of the at least one module being invoked (i.e., the optimal frequency does not cause resonance of the module being invoked), then the target frequency may be determined to be the optimal frequency. In another example, the target frequency is determined to be an optimal frequency if the current frequency does not match the vibration frequency of the at least one module being invoked (i.e., the current frequency does not cause resonance of the at least one module being invoked), and the optimal frequency does not match the vibration frequency of the at least one module being invoked (i.e., the optimal frequency does not cause resonance of the module being invoked). In yet another example, the target frequency is determined to be the current frequency if the current frequency does not match the vibration frequency of the at least one module being invoked (i.e., the current frequency does not cause resonance of the at least one module being invoked), and the optimal frequency matches the vibration frequency of the at least one module being invoked (i.e., the optimal frequency may cause resonance of the module being invoked). In yet another example, if the current frequency matches the vibration frequency of the at least one module being invoked (i.e., the current frequency may cause resonance of the at least one module being invoked), and the optimal frequency matches the vibration frequency of the at least one module being invoked (i.e., the optimal frequency may cause resonance of the module being invoked), the electronic device re-executes S503-S504, and upon executing S503, the electronic device may select a maximum of the other efficiency values in addition to the maximum efficiency value to continue executing S504 and S505. If the re-selected optimal frequency still does not meet the condition, the frequency corresponding to the smaller efficiency value can be selected continuously.

In another possible implementation, if the difference in efficiency between the optimal frequency and the current frequency is less than the preset threshold, it may be determined that no switching to the optimal frequency is required, i.e. S505 is not performed, i.e. in this example, the efficiency is the optimal choice condition, which may cause resonance interference.

In yet another possible implementation, if the efficiency difference between the optimal frequency and the current frequency is less than a preset threshold. The electronic device further executes S505. In one example, the target frequency is determined to be the current frequency if neither the optimal frequency nor the current frequency matches the resonant frequency of the at least one module being invoked. In another example, the target frequency is determined to be the current frequency if the optimal frequency matches none of the resonant frequencies of the at least one module being invoked and the current frequency does not match none of the resonant frequencies of the at least one module being invoked. In yet another example, the target frequency is determined to be the current frequency if none of the optimal frequencies match the resonant frequency of the at least one module being invoked and the current frequency matches the resonant frequency of the at least one module being invoked. In yet another example, if the current frequency matches the vibration frequency of the at least one module being invoked (i.e., the current frequency may cause resonance of the at least one module being invoked), and the optimal frequency matches the vibration frequency of the at least one module being invoked (i.e., the optimal frequency may cause resonance of the module being invoked), the electronic device re-executes S503-S504, and upon executing S503, the electronic device may select a maximum of the other efficiency values in addition to the maximum efficiency value to continue executing S504 and S505. If the re-selected optimal frequency still does not meet the condition, the frequency corresponding to the smaller efficiency value can be selected continuously.

In one possible implementation, the electronic device may not perform S504, i.e., the electronic device may perform S505 after determining the optimal frequency.

In another possible implementation, the electronic device may not perform S505, i.e. not consider interference issues, but rather prioritize maximum efficiency.

In yet another possible implementation, the electronic device may execute S505 first and then execute S504, which is not limited by the present application. That is, the electronic device may first detect whether the current frequency and the optimal frequency cause resonance of other modules. If neither the optimal frequency nor the current frequency causes resonance, S504 is performed again to determine whether or not switching to the optimal frequency is possible. If the optimal frequency does not cause resonance and the current frequency does cause resonance, the switching to the optimal frequency may be directly performed without S504. If the optimal frequency and the current frequency both cause resonance, other frequencies that do not cause resonance are selected as the optimal frequencies, and S504 is performed. If the optimal frequency would cause resonance and the current frequency would not, S504 may not be performed, i.e. the current frequency is still maintained. Alternatively, if the optimal frequency causes resonance but the current frequency does not, the optimal frequency may be reselected (i.e., the efficiency of selection is slightly lower than that of the current frequency, as described above), and S504 is performed.

S506, updating the frequency of the charging IC to the target frequency.

For example, after the electronic device determines the target frequency, the frequency of the charging IC may be updated to the target frequency. For example, the charge management module may write a target frequency to a register of the charging IC to indicate a register update frequency.

The flow in fig. 5 is described in detail below in connection with some application scenarios.

Scene one:

in this scenario, taking an example of switching the electronic device from standby to light-load, for example, the electronic device is charged in a standby state, and during charging, the user switches the electronic device from the standby state to an unlocked state, and after unlocking, browses a web page using the electronic device. In the embodiment of the application, the light load state may refer to a lower load state (including data transmission, memory occupation, battery use, etc.) of the electronic device, and the heavy load state may refer to a higher load state of the electronic device.

Specifically, in the standby state, if the electronic device detects that the electronic device is being charged, S502 to S504 are started to be executed, so as to obtain the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device detects that it is currently in standby mode, which normally does not invoke the modules involved in the second database matrix. Therefore, when executing S505, the electronic apparatus may determine that the optimal frequency is the target frequency in the case where it is determined that the frequency can be switched. It should be noted that, during charging in the standby state, since the current, voltage and/or temperature of the charging IC may change, the optimal frequency obtained when the electronic device executes the flow of fig. 5 every cycle may be the same or different, which is not limited by the present application. For example, at the initial time, the electronic device sets the frequency of the charging IC to a default frequency (may be set according to actual requirements, and the present application is not limited). At the first periodic trigger time, the electronic device executes the flow of fig. 5, and obtains the optimal frequency (denoted as the second frequency). The optimal frequency may be different from the default frequency. The electronic device may determine the target frequency based on the flow chart in fig. 5, for example, the target frequency is the optimal frequency (i.e., the second frequency), and the electronic device switches the current frequency of the charging IC (i.e., the default frequency) to the second frequency. At the third period trigger time, the electronic device continues to execute the flow in fig. 5, and may determine that the target frequency is the third frequency. Wherein the third frequency may be different from the second frequency due to an increase in the temperature of the charging IC caused by the charging. Accordingly, the electronic device determines the target frequency based on the flow in fig. 5. For example, the target frequency is the third frequency, the electronic device switches the current frequency (i.e., the second frequency) of the charging IC to the third frequency.

For example, in the present scenario, after the electronic device starts the browser application and displays the web page in response to the received user operation during the charging process, it is assumed that the nth detection period is reached. And at the period triggering moment, the electronic equipment starts to execute S502-S504 so as to acquire the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device acquires that the browser application is currently running, and determines, based on the third database matrix (or information fed back by the browser application), a module called by the browser application (i.e., a running module) includes, but is not limited to: a screen and a sensor. The electronic device may select a corresponding target frequency based on the vibration frequencies of the screen and the sensor when performing S505. It is assumed that the current frequency matches the vibration frequency of the screen, while the optimal frequency does not match the vibration frequency of both the screen and the sensor. The electronic device may determine the optimal frequency as the target frequency and switch the frequency of the charging IC to the target frequency, i.e., the optimal frequency. Therefore, under a light-load scene, the charging IC is maintained at the maximum charging efficiency, the influence on a module called by a user is avoided, and the influence (such as clamping and the like) of charging on the application is reduced.

Scene II:

in this scenario, taking the example of the electronic device switching from a light load to a standby scenario, a user uses the electronic device to browse the interface of the video application to view video, for example. Subsequently, the electronic device switches to a standby state in response to the received user operation. I.e. charging continues in standby state.

Specifically, in the process of browsing the video by the user, the electronic device detects that the electronic device is being charged, and S502 to S504 are executed to obtain the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device detects that the currently running application is a video application, and determines, based on the third database matrix, modules invoked by the video application (i.e., running modules) include, but are not limited to: audio, screen and sensor, etc. The electronic device may select a corresponding target frequency based on the vibration frequencies of the screen and the sensor when performing S505. It is assumed that the current frequency matches the vibration frequency of the screen, while the optimal frequency does not match the vibration frequency of both the screen and the sensor. The electronic device may determine the optimal frequency as the target frequency and switch the frequency of the charging IC to the target frequency, i.e., the optimal frequency.

Next, the electronic device switches to a standby mode in response to a received user operation (e.g., a user clicking on a switch key). That is, the electronic device is charged in the standby mode. And when the electronic equipment detects that the electronic equipment is being charged, starting to execute S502-S504 to acquire the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device detects that it is currently in standby mode, which normally does not invoke the modules involved in the second database matrix. Therefore, when executing S505, the electronic apparatus may determine that the optimal frequency is the target frequency in the case where it is determined that the frequency can be switched. In this way, according to different modules called in different scenes, the electronic device can decouple the frequency of the charging IC based on the vibration frequency of the modules in different scenes, so as to avoid resonance of other modules caused by the frequency of the charging IC. Therefore, the requirements of different scenes are met by dynamically adjusting the frequency of the charging IC. Namely, in different scenes, the maximization of the charging efficiency is achieved, and meanwhile, the interference to other modules is avoided.

Scene III:

in this scenario, taking the example of the electronic device switching from a light load to a heavy load scenario, a user uses the electronic device to browse the interface of the video application to view video, for example. Subsequently, during the charging of the electronic device, the user plays a game using the electronic device.

The electronic device then runs the gaming application in response to the received user operation. And when the electronic equipment detects that the electronic equipment is being charged, starting to execute S502-S504 to acquire the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device obtains that the game application is currently running, and determines, based on the third database matrix, modules invoked by the game application (i.e., modules that are running) include, but are not limited to: a screen and a sensor. The electronic device may select a corresponding target frequency based on the vibration frequencies of the screen and the sensor when performing S505. The electronic equipment runs the browser application and the game application, and the screen and the sensor are called, but in the running process, the electronic equipment is in a heavy-load state due to the fact that the game application runs, and accordingly the temperature of the charging IC is higher than that of the charging IC when the video application is browsed. Thus, the optimal frequencies selected by the electronic devices may not be the same. For other descriptions, reference is made to the above, and no further description is given here.

Scene four:

in this scenario, taking the electronic device switching from a heavy load to a light load scenario as an example, a user plays a game using the electronic device during charging of the electronic device. The user then uses the electronic device to browse the interface of the video application to view the video.

The electronic device runs the gaming application in response to the received user operation. And when the electronic equipment detects that the electronic equipment is being charged, starting to execute S502-S504 to acquire the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device obtains that the game application is currently running, and determines, based on the third database matrix, modules invoked by the game application (i.e., modules that are running) include, but are not limited to: a screen and a sensor. The electronic device may select a corresponding target frequency based on the vibration frequencies of the screen and the sensor when performing S505.

In the process of browsing videos by a user, the electronic equipment detects that the electronic equipment is being charged, and S502-S504 are executed to acquire the optimal frequency and the current frequency. The specific flow may be referred to above, and will not be described herein. In the current scenario, the electronic device detects that the currently running application is a video application, and determines, based on the third database matrix, modules invoked by the video application (i.e., running modules) include, but are not limited to: audio, screen and sensor, etc. The electronic device may select a corresponding target frequency based on the vibration frequencies of the screen and the sensor when performing S505. It is assumed that the current frequency matches the vibration frequency of the screen, while the optimal frequency does not match the vibration frequency of both the screen and the sensor. The electronic device may determine the optimal frequency as the target frequency and switch the frequency of the charging IC to the target frequency, i.e., the optimal frequency. Also, the temperature of the charging IC may decrease due to the electronic device switching from heavy load to light load. Therefore, the optimal frequency selected by the electronic device at light load may not be the same as the optimal frequency selected at heavy load. That is, the frequency selection of the charging IC will vary with scene changes.
