Technical Field

The embodiment of the application relates to the technical field of electronic equipment, in particular to a charging method and device and electronic equipment.

Background

The user can charge the electronic equipment while using the electronic equipment so as to avoid the influence on normal use caused by low or exhausted electric quantity of the electronic equipment. The electronic device generates corresponding power consumption when running an application used by a user, and the power consumption can cause temperature rise of the electronic device. Meanwhile, the charging circuit of the electronic equipment also generates charging heat, so that the temperature rise of the electronic equipment is increased, and the battery temperature of the electronic equipment is easily caused to be too high. Excessive battery temperature can affect the charge and discharge performance of an electronic device, for example, by disrupting chemical equilibrium within the battery, resulting in battery capacity degradation, even explosions, and the like.

In order to avoid the situation that the battery temperature of the electronic equipment is too high when the electronic equipment is used while being charged, the electronic equipment detects the current battery temperature in real time, so that when the battery temperature reaches a threshold value, the charging current is reduced, the charging heat generated by a charging circuit is reduced, and the battery temperature of the electronic equipment is reduced. However, when the electronic device detects that the charging current needs to be reduced, the battery temperature of the electronic device is already high, and the charging current is reduced at this time, so that the cooling speed of the electronic device is also slow, and therefore, the manner of adjusting the charging current according to the current battery temperature of the electronic device cannot effectively control the battery temperature of the electronic device.

The user charges the electronic equipment while using the electronic equipment so as to avoid the influence on normal use caused by low or exhausted electric quantity of the electronic equipment. At this time, the electronic device is in a use scenario of running the application while charging, and when running the application, the electronic device generates corresponding power consumption, and this part of power consumption may cause temperature rise of the electronic device. Meanwhile, the charging circuit of the electronic equipment also generates charging heat, so that the temperature rise of the electronic equipment is increased, and the battery temperature of the electronic equipment is easily caused to be too high. In order to avoid the situation that the battery temperature of the electronic equipment is too high when the electronic equipment is used while being charged, the electronic equipment detects the current battery temperature in real time, so that when the battery temperature reaches a battery temperature threshold value, the charging current is reduced, the charging heat generated by a charging circuit is reduced, and the battery temperature of the electronic equipment is reduced. Taking the electronic equipment as a mobile phone for example, the battery temperature threshold of the mobile phone is set to 45 ℃, if the mobile phone detects that the battery temperature is greater than or equal to 45 ℃, the mobile phone reduces charging current, such as reducing charging power, reducing adapter current, reducing cable current, reducing impedance current and the like, and after the charging current is reduced, the charging heat of the mobile phone is also reduced. However, when the mobile phone detects that the charging current needs to be reduced, the battery temperature of the mobile phone is already high, which can affect the performance of the mobile phone. In addition, even if the charging current is reduced, the temperature of the mobile phone needs to be reduced for a certain period of time, and the battery temperature of the mobile phone is still high in the period of time, so that the performance of the mobile phone can be continuously influenced.

Taking the electronic equipment as a mobile phone as an example, in some use scenarios, a user makes a call while charging the mobile phone, a background of the mobile phone runs a shopping application, and a display screen of the mobile phone is in a bright screen state. In the above scenario, the mobile phone runs the call application and the shopping application at the same time, and the 5G module and the screen module are both in the power supply mode. The application in the running state and the module in the power supply mode can generate power consumption for the mobile phone, so that the mobile phone is heated.

In order to solve the above-mentioned problems, the embodiment of the present application provides a charging method. When the electronic equipment is charged and the application is operated, the charging current can be reduced in advance according to the historical power consumption of the operated application, and/or the operation power consumption and the charging heating of the electronic equipment can be reduced by limiting the mode of the operated application and the module, so that the battery temperature of the electronic equipment is effectively controlled.

Fig. 2 is a flowchart of a charging method 200 provided in an embodiment of the present application, as shown in fig. 2, the method 200 includes the following steps S201-S203:

in step S201, the electronic device determines a first application when charging. The first application is a foreground-running application.

In the embodiment of the present application, the application being used by the user is a foreground running application, i.e. a first application. The first application is N, wherein N is more than or equal to 1, and N is an integer. The electronic device determines a first application by detecting an application run by the foreground. For example: if the electronic equipment detects that the application running in the foreground is a call application, the call application is a first application. Another example is: if the electronic device detects that the applications running in the foreground are a music application and a news application, the music application and the news application are first applications.

In step S202, the electronic device determines a power consumption model corresponding to the first application.

The electronic device may pre-establish the power consumption model based on historical operating data of the first application. Wherein the historical operating data of the first application includes at least one of: the method comprises the steps of operating frequency of a first application, increasing the overall power consumption of the electronic device by the first application during operation, depending on each hardware module by the first application, associating the first application with other applications, and generating the power consumption module during operation of the first application.

The association degree of the first application and other applications is used for representing the association relation between the first application and other applications. In the embodiment of the present application, the association relationship between applications refers to a call relationship between applications. For example: if the normal operation of the application A needs to call the data of the application B, the application A and the application B have an association relation.

The degree of dependence of the first application on each hardware module is used for representing the dependence relationship between the first application and the hardware module. In the embodiment of the application, the dependency relationship between the application and the module refers to that the running of the application needs to depend on the work of the module. For example: when the game application is running, the screen needs to be in a bright screen state to display the game picture through the screen, that is, the running of the game application needs to depend on the operation of the screen module, that is, the game application and the screen module have a dependency relationship.

Therefore, the running of the application with the association relation of the first application and the power supply state of the module with the association relation of the first application are guaranteed, and the requirements for keeping the normal running of the first application are met.

The power consumption model may be a neural network model, an array, a linked list, a class, etc.

Taking electronic equipment as a mobile phone and a power consumption model as a neural network model as an example for explanation: and in the process of using the first application in the non-charging state, the mobile phone records the operation data of the first application, and carries out iterative learning through a neural network according to the operation data recorded each time so as to obtain a power consumption model. The mobile phone inputs the name of the first application in the power consumption model, so that the power consumption of the first application to be generated in a specified time period can be predicted, the application with the association relation with the first application is determined, and the module with the dependence relation with the first application is determined.

Taking electronic equipment as a mobile phone and a power consumption model as an array as an example for explanation: and in the process of using the first application in the non-charging state, the mobile phone records the running data of the first application, and establishes an array according to the name and the running data of the first application, such as 'the name of the first application-the running data'. And the electronic equipment updates the array according to the operation data recorded each time to obtain a power consumption model. The mobile phone can determine a corresponding array according to the name of the first application, and further determine operation data corresponding to the first application according to the determined array.

The power consumption model may include one or more models, that is, a module that predicts power consumption to be generated by the first application within a specified period of time through one model, determines an application having an association relationship with the first application, and determines a dependency relationship with the first application. The power consumption to be generated by the first application in a specified time period can be predicted through a plurality of models, the application with the association relation with the first application is determined, and the module with the dependency relation with the first application is determined.

In step S203, the electronic device adjusts the charging power and/or its own power consumption according to the power consumption model.

When the electronic equipment is charged, the power consumption to be generated by the first application in the appointed time period can be predicted directly according to the established power consumption model, the application with the association relation with the first application is determined, and the hardware module with the association relation with the first application is used for improving the efficiency of acquiring the power consumption data corresponding to the first application. The electronic device may determine the charging power to be used according to the predicted power consumption, and determine the manner of adjusting the power consumption of the electronic device according to the application having the association relationship with the first application and the hardware module having the dependency relationship with the first application. Therefore, the electronic equipment can be charged in a mode of pre-using the determined charging power and/or adjusting the power consumption before the battery temperature reaches the temperature threshold value, so that the battery temperature is prevented from reaching the temperature threshold value, and damage to the battery is avoided.

The method 200 is described in connection with the following examples:

the following is a first embodiment of the present application.

A first embodiment of the present application provides a charging method. In a first embodiment, an electronic device adjusts charging power according to a power consumption model. Fig. 3 is a flowchart of a charging method 300 provided in the first embodiment of the present application. As shown in fig. 3, the method 300 includes the following steps S301-S303:

in step S301, the electronic device determines a first application when charging.

In the embodiment of the application, the electronic device adopts default charging power during charging, and the charging power is not adjusted along with the rise of the battery temperature, or is reduced after the battery temperature reaches the temperature threshold. The electronic device may start a first charging mode according to the following implementation manner, where the electronic device dynamically adjusts the charging power in the first charging mode:

in one implementation, the electronic device initiates a first charging mode in response to a control instruction entered by a user.

In another implementation, the electronic device automatically turns on the first charging mode when detecting that the current battery temperature is greater than or equal to the first temperature threshold. Wherein the first temperature threshold is smaller than the temperature threshold in the second charging mode, i.e. when the battery temperature of the electronic device reaches the first temperature threshold, no influence is exerted on the battery performance.

In the embodiment of the present application, the power consumption generated by the first application during the running process may be referred to as effective power consumption. In any state of the electronic device (including a charged state and a non-charged state), effective power consumption is unavoidable, that is, a temperature rise caused by the effective power consumption to the electronic device is unavoidable. When the electronic equipment is charged, the effective power consumption and the overall temperature rise generated by charging and heating can be reduced by reducing the charging and heat generation, so that the battery temperature of the electronic equipment is effectively controlled.

Step S302, the electronic device predicts and obtains first power consumption corresponding to the first application according to the power consumption model. The first power consumption is power consumption to be generated by the first application within a specified period of time.

The electronic device may obtain the first power consumption corresponding to the first application based on a pre-established power consumption model (e.g., a neural network model, an array, a linked list, a class, etc.).

Taking electronic equipment as a mobile phone, a power consumption model as a neural network model, and a first application as a call application as an example for explanation: the mobile phone inputs the name of the call application into the neural network model, and predicts the first power consumption to be generated by the call application, such as 800mW.

Taking electronic equipment as a mobile phone, a power consumption model as an array, and a first application as a call application as an example for explanation: the mobile phone determines a corresponding array of 'call-800 mW' according to the name of the call application, and further predicts and obtains the power consumption to be generated by the call application, namely 800mW.

In step S303, the electronic device reduces the charging power according to the first power consumption.

The electronic equipment can reduce the charging power in advance according to the first power consumption before the battery temperature of the electronic equipment reaches the temperature threshold so as to reduce the charging heat generation, thereby effectively controlling the first power consumption and the reduced charging power to generate the whole heat to the electronic equipment, further effectively controlling the battery temperature of the electronic equipment and avoiding the battery temperature from reaching the temperature threshold. Wherein, the higher the value of the first power consumption, the smaller the value of the reduced charging power.

The charging method provided in the first embodiment of the present application is further described below with reference to an example.

Taking the electronic device as a mobile phone and the first application as a call application as an example, the steps of the charging method 200 performed by the electronic device are exemplarily described. The example includes steps corresponding to steps S301-S303, respectively, in the method 300 shown in fig. 3.

When the mobile phone is charged, the user uses the call application to make a call. The mobile phone detects that the application operated by the foreground is a call application. The mobile phone predicts the first power consumption corresponding to the call application through a pre-established power consumption model (array). Taking the example that an array of 'call-800 mW' is pre-stored in the mobile phone, the mobile phone acquires the array of 'call-800 mW' according to the name of the call application, and further determines that the first power consumption corresponding to the call application is 800mW. The mobile phone reduces the charging power in advance according to the first power consumption '800 mW' corresponding to the call application. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 2 ℃ according to the first power consumption of 800mW, and reduces the charging power by reducing the charging power, and reduces the current charging power of 20W to 10W in advance so as to reduce the increase of the battery temperature. Therefore, the actual power consumption generated by the mobile phone running call application and the overall heat generated by the mobile phone when the mobile phone is charged by using the charging power of 10W are relatively low, and the temperature rise of the battery can be effectively controlled, so that the battery temperature of the mobile phone can be effectively controlled.

The charging method provided in the first embodiment of the present application is further described below with reference to another example.

Taking the electronic device as a mobile phone, the first application as a music application and a news application as examples, the steps of the charging method 300 performed by the electronic device are exemplarily described. The example includes steps corresponding to steps S301-S303, respectively, in the method 300 shown in fig. 3.

When the mobile phone is charged, the user plays music by using the music application and browses news by using the news application. The mobile phone detects that the applications operated by the foreground are music applications and news applications. The mobile phone predicts the first power consumption corresponding to the music application and the news application through a pre-established power consumption model (neural network model). In one implementation, the name "music" of the music application and the name "news" of the news application are input in the neural network model by the mobile phone, so as to respectively predict the first power consumption corresponding to the music application, such as 75mW, and the first power consumption corresponding to the news application, such as 150mW, and the mobile phone calculates the sum (or the weighted value) of the first power consumption corresponding to the music application and the first power consumption corresponding to the news application as the first power consumption for final use. In another implementation manner, the mobile phone inputs the name "music" of the music application and the name "news" of the news application in the neural network model, and can directly predict and obtain the corresponding comprehensive power consumption (the comprehensive power consumption can be corresponding to the sum of the first power consumption of the music application and the first power consumption of the news application or a weighted value), and the comprehensive power consumption is the first power consumption of the final use. Taking the final first power consumption as the sum of the first power consumption of the music application and the first power consumption of the news application as an example, the final first power consumption is 225mW. The mobile phone reduces the charging power in advance according to the first power consumption corresponding to the music application and the first power consumption corresponding to the news application, namely the first power consumption for final use is 225mW. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 0.5 ℃ according to the first power consumption 225mW, and reduces the charging power by reducing the charging power, and reduces the current charging power 20W to 5W so as to reduce the increase of the battery temperature. Therefore, the actual power consumption generated by running the music application and the news application on the mobile phone and the overall heat generated by the mobile phone by the charging heat generated by charging the mobile phone with the charging power of 5W are relatively low, and the temperature rise of the battery can be effectively controlled, so that the battery temperature of the mobile phone is effectively controlled.

Fig. 4 is a schematic diagram of a change of battery temperature of an analog mobile phone in different usage scenarios and charging modes according to an embodiment of the present application. In fig. 4 (1), the battery temperature is changed with time when the mobile phone is charged in an idle state, the charging power of the mobile phone is 20W, and the battery temperature is maintained at 33-34 ℃ basically after the battery is warmed up. In fig. 4, (2) is a schematic diagram of the battery temperature changing with time after the mobile phone is charged under the CPU load state and the first charging mode is started, the charging power of the mobile phone is reduced to 5W, and the battery temperature is maintained at 41-44 ℃ substantially without reaching 45 ℃ after the battery is warmed up. In fig. 4 (3), the mobile phone is charged in the CPU load state, and the first charging mode is not started, and the battery temperature changes with time, where the CPU load state of the mobile phone is the same as the CPU load state of the mobile phone shown in fig. 4 (2), the charging power of the mobile phone is still 20W, and the battery temperature exceeds 45 ℃ after the battery is warmed up. As can be seen from comparison of (1) - (3) in fig. 4, after the mobile phone starts the first charging mode, charging and heating can be effectively reduced, so that temperature rise of the battery is effectively controlled, the battery temperature is controlled below a temperature threshold value of 45 ℃, and damage to the battery is avoided.

In the embodiment of the application, when the electronic device is running while charging, the power consumption to be generated by the currently running application can be predicted, and the charging power is reduced in advance according to the power consumption before the battery temperature of the electronic device reaches the temperature threshold value, so as to reduce the charging heat generation, thereby effectively controlling the overall heat generated by the power consumption generated by running the application and the charging heat generated by charging on the electronic device, further effectively controlling the battery temperature of the electronic device, and avoiding the battery temperature from reaching the temperature threshold value.

The following is a second embodiment of the present application.

A second embodiment of the present application provides a charging method. In a second embodiment, the electronic device adjusts the charging power according to a power consumption model. Fig. 5 is a flowchart of a charging method 500 provided in a second embodiment of the present application. As shown in fig. 5, the method 500 includes steps S501-S503, where step S502 is similar to step S302, and is not repeated here. The following description is made of step S501 and step S503:

in step S501, the electronic device acquires a first application while charging. The electronic device also obtains a second power consumption. The second power consumption is a current power consumption of the first application.

In the embodiment of the application, the electronic device may calculate the power consumption corresponding to the first application by obtaining the current power consumption of the SoC, that is, the second power consumption, where the second power consumption is the actual power consumption generated by the first application in the current use process.

In step S503, the electronic device decreases the charging power according to the weighted value of the first power consumption and the second power consumption.

In this embodiment of the present application, the electronic device may configure weight values for the first power consumption and the second power consumption in advance, where the first power consumption (P1) and the second power consumption (P2) satisfy the following formulas:

P＝k1·P1+k2·P2

wherein P represents a weighted value of the first power consumption and the second power consumption, k1 represents a weighted value corresponding to the first power consumption, k2 represents a weighted value corresponding to the second power consumption, and k1+k2=1.

Therefore, the electronic equipment determines the charging power to be used by combining the first power consumption (the power consumption to be generated by the first application in the current use process) and the second power consumption (the actual power consumption of the first application to date in the current use process), and the obtained charging power is determined to integrate the historical performance and the current actual performance of the first application, so that the reliability is higher, and the battery temperature can be controlled accurately.

The charging method provided in the second embodiment of the present application is further described below with reference to an example.

Taking the electronic device as a mobile phone and the first application as a call application as an example, the steps of the charging method 500 performed by the electronic device are exemplarily described. The example includes steps corresponding to steps S501-S503, respectively, in the method 500 shown in fig. 5.

When the mobile phone is charged, the user uses the call application to make a call. The mobile phone detects that the application operated by the foreground is a call application. The mobile phone obtains the second power consumption generated so far in the use process of the call application, for example, the second power consumption is 400mW. The mobile phone acquires first power consumption corresponding to the call application through a pre-established power consumption model (array). Taking the example that an array of 'call-800 mW' is pre-stored in the mobile phone, the mobile phone acquires the array of 'call-800 mW' according to the name of the call application, and further determines that the first power consumption corresponding to the call application is 800mW. The mobile phone calculates a weighted value according to the first power consumption '800 mW' and the second power consumption '400 mW' corresponding to the call application. Taking the example that the weight value of the first power consumption is 0.6 and the weight value of the second power consumption is 0.4, the weight value of the first power consumption and the second power consumption is 640mW, and the mobile phone reduces the charging power in advance according to 640 mW. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 1.5 ℃ according to the weighted value 640mW of the first power consumption and the second power consumption, and reduces the charging power by reducing the charging power, and reduces the current charging power by 20W to 15W so as to reduce the increase of the battery temperature.

In the embodiment of the application, the electronic device determines the charging power to be used by combining the first power consumption and the second power consumption, and the determined charging power integrates the historical power consumption and the current actual power consumption of the first application, so that the reliability is higher, and the battery temperature can be controlled accurately.

The following is a third embodiment of the present application.

A third embodiment of the present application provides a charging method. The electronic device adjusts its own power consumption according to the power consumption model. Fig. 6 is a flowchart of a charging method 600 provided in a third embodiment of the present application. As shown in fig. 6, the method 600 includes the following steps S601-S603:

in step S601, the electronic device determines a first application, a second application, and a first module when charging. The second application refers to an application running in the background, and the first module refers to a module that currently generates power consumption.

In the embodiment of the application, the electronic device defaults to not adjust its power consumption along with the battery temperature when charging. The electronic device may turn on the first charging mode in reference to step S201, which is not described herein. In the first charging mode, the electronic device dynamically adjusts its own power consumption.

In the embodiment of the application, the application that is started in the electronic device but is not used by the user is the application running in the background, namely, the second application. The second application is M, wherein M is more than or equal to 0, and M is an integer. The module which is communicated with the battery is a module in a power supply state, namely a first module. And the electronic equipment acquires the second application by detecting the application running in the background. For example: if the electronic device detects that the application running in the background is a video application, the second application is a video application. The electronic equipment acquires the first module through detecting the communication state of the module and the battery. For example: the electronic equipment detects that the communication state of the screen module and the battery is on, and the screen module is a first module.

In step S602, the electronic device determines at least one third application and at least one second module according to the power consumption model. The third application refers to an application which has no association relation with the first application in the second application, and the second module refers to a module which has no dependency relation with the first application in the first module.

The electronic device may obtain an application (i.e., a fourth application) having an association relationship with the first application and a module (i.e., a third module) having a dependency relationship with the first application based on a pre-established power consumption model (e.g., a neural network model, an array, a linked list, a class, etc.). And the electronic equipment eliminates the fourth application from the second application to obtain a third application, namely, an application which has no association relation with the first application in the application running in the background. And the electronic equipment eliminates the third module from the first module to obtain a second module, namely a module which has no dependency relationship with the first application in the modules in the power supply mode.

In step S603, the electronic device closes the third application and/or limits the power supply to the second module.

Because the first application and the third application have no association relationship, the first application and the second module have no dependence relationship, and therefore, the third application is exited and/or the power supply to the second module is limited, and the normal operation of the first application is not influenced.

In one implementation, the electronic device only closes the third application, yet maintains normal power to the second module.

In one implementation, the electronic device limits power to the second module, such as reducing power current to the second module, or disconnects power to the second module without shutting down the third application.

In one implementation, the electronic device shuts down the third application and limits power to the second module, such as reducing power supply current to the second module or disconnecting power to the second module.

In some embodiments, if the electronic device closes the third application, the electronic device preferentially closes a fifth application, where the fifth application is i applications (1. Ltoreq.i.ltoreq.P, and i is an integer) that have a history of power consumption from high to low among the P third applications and are top-ranked. Therefore, the electronic equipment does not need to close all the third applications at one time so as to reserve part of the third applications for direct use by a user, and the operation steps of opening the part of the third applications by the user are simplified. Further, if the electronic device monitors that the temperature of the battery is rising faster or the temperature is higher, all third applications are shut down.

In some embodiments, if the electronic device limits the power supply of the second module, the electronic device preferentially limits the fourth module, wherein the fourth module is j modules (1. Ltoreq.j. Ltoreq.q, and j is an integer) of the Q second modules that have a history of power consumption from high to low. Therefore, the electronic equipment does not need to limit the power supply of all the second modules at one time so as to keep the normal power supply of part of the second modules, thereby ensuring the normal operation of the part of the second modules and enabling the user to normally experience the functions realized by the part of the second modules. Further, if the electronic device monitors that the temperature of the battery is rising faster or the temperature is higher, the power supply of all the second modules is restricted.

The charging method provided in the third embodiment of the present application is further described below with reference to an example.

Taking the electronic device as a mobile phone and the first application as a call application as an example, the steps of the charging method 600 performed by the electronic device are exemplarily described. The example includes steps corresponding to steps S601-S603 in the method 600 shown in fig. 6, respectively.

When the mobile phone is charged, the user uses the call application to make a call. The mobile phone detects that a first application running in the foreground is a call application, a second application running in the background is a music application, and a first module in a power supply mode is a 5G module, a screen module, a GPU module and a Wi-Fi module. The mobile phone determines that a third application which has no association relation with the call application in the second application is a music application through a pre-established power consumption model (neural network model), and a second module which has no dependency relation with the call application in the first module is a screen module, a GPU module and a Wi-Fi module. The mobile phone exits the music application, and limits the power supply to the screen module, the GPU module and the Wi-Fi module, for example, the Wi-Fi module is adjusted to be in a dormant mode, so that the power supply current to the screen module is reduced, the brightness of the screen is reduced, and the power supply to the GPU module is disconnected.

The charging method provided in the third embodiment of the present application is further described below with reference to another example.

The user plays a game using the game application while the handset is charged. The mobile phone detects that a first application running in the foreground is a game application, a second application running in the background is a video application, and a first module in a power supply mode is a 5G module, a screen module, a GPU module and a Wi-Fi module. The mobile phone determines that a third application which has no association relation with the game application in the second application is a video application through a pre-established power consumption model (neural network model), and a second module which has no dependency relation with the game application in the first module is a 5G module. The handset exits the video application and limits power to the 5G module, such as disconnecting power to the 5G module.

The charging method provided in the third embodiment of the present application is further described below with reference to still another example.

The user uses the social application chat while the phone is charging. The mobile phone detects that a first application running in the foreground is a social application, a second application running in the background is a gallery application and a video application, and a first module in a power supply mode is a 5G module, a screen module and a Bluetooth module. The mobile phone determines that a third application which has no association relation with the social application in the second application is a video application through a pre-established power consumption model (neural network model), and a second module which has no dependency relation with the social application in the first module is a Bluetooth module. The handset exits the video application and limits power to the bluetooth module, such as disconnecting power to the bluetooth module.

In the embodiment of the application, when the electronic device runs the application while charging, the application which has no association relationship with the first application can be closed, and/or the power supply to the module which has no association relationship with the first application is limited, so that the application and the module can be prevented from generating power consumption to the electronic device, the battery temperature of the electronic device can be effectively controlled, and the battery temperature can be prevented from reaching the temperature threshold.

The following is a fourth embodiment of the present application.

A fourth embodiment of the present application provides a charging method. In this embodiment, the electronic device adjusts the charging power and its own power consumption according to the power consumption model. Fig. 7 is a flowchart of a charging method 700 provided in a fourth embodiment of the present application. As shown in fig. 7, the method 700 includes the following steps S701-S703:

The electronic device may turn on the first charging mode in reference to step S301, which is not described herein. In the first charging mode, the electronic device dynamically adjusts the charging power and its own power consumption.

The example includes steps corresponding to steps S701-S703, respectively, in the method 700 shown in fig. 7.

When the mobile phone is charged, the user uses the call application to make a call. The mobile phone detects that a first application running in the foreground is a call application, a second application running in the background is a music application, and a first module in a power supply mode is a 5G module, a screen module, a GPU module and a Wi-Fi module. The mobile phone obtains a first power consumption of 800mW corresponding to a call application through a pre-established power consumption model (a neural network model), determines a third application which has no association relation with the call application in the second application as a music application, and a second module which has no dependence relation with the call application in the first module as a screen module, a GPU module and a Wi-Fi module. The mobile phone exits the music application, and limits the power supply to the screen module, the GPU module and the Wi-Fi module, for example, the Wi-Fi module is adjusted to be in a dormant mode, so that the power supply current to the screen module is reduced, the brightness of the screen is reduced, and the power supply to the GPU module is disconnected. And pre-reducing the charging power according to the first power consumption '800 mW' corresponding to the call application. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 2 ℃ according to the first power consumption of 800mW, and the mobile phone reduces the charging power by reducing the charging power, so that the current charging power of 20W is reduced to 10W in advance.

The charging method provided in the fourth embodiment of the present application is further described below with reference to another example.

The mobile phone detects that a first application running in the foreground is a game application, a second application running in the background is a video application, and a first module in a power supply mode is a 5G module, a screen module, a GPU module and a Wi-Fi module. The mobile phone acquires first power consumption of 1200mW corresponding to the game application through a pre-established power consumption model (neural network model), determines a third application which has no association relation with the game application in the second application as a video application, and determines a second module which has no dependence relation with the game application in the first module as a 5G module. The handset exits the video application and limits power to the 5G module, such as disconnecting power to the 5G module. And pre-reducing the charging power according to the first power consumption '1200 mW' corresponding to the game application. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 3 ℃ according to the first power consumption of 1200mW, and the mobile phone reduces the charging power by reducing the charging power, so that the current charging power of 20W is reduced to 5W in advance.

The charging method provided in the fifth embodiment of the present application is further described below with reference to an example.

Taking the electronic device as a mobile phone and the first application as a call application as an example, the steps of the charging method 800 performed by the electronic device are exemplarily described. The example includes steps corresponding to steps S801-S803, respectively, in the method 800 shown in fig. 8.

When the mobile phone is charged, the user uses the call application to make a call. The mobile phone detects that a first application running in the foreground is a call application, a second application running in the background is a music application, and a first module in a power supply mode is a 5G module, a screen module, a GPU module and a Wi-Fi module. And, the mobile phone obtains the second power consumption generated so far in the use process of the call application, for example, the second power consumption is 400mW. The mobile phone acquires first power consumption corresponding to the call application through a pre-established power consumption model (array). Taking the example that an array of 'call-800 mW' is pre-stored in the mobile phone, the mobile phone acquires the array of 'call-800 mW' according to the name of the call application, and further determines that the first power consumption corresponding to the call application is 800mW. And determining that a third application which has no association relation with the call application in the second application is a music application through a pre-established power consumption model, and a second module which has no dependency relation with the call application in the first module is a screen module, a GPU module and a Wi-Fi module. The mobile phone exits the music application, and limits the power supply to the screen module, the GPU module and the Wi-Fi module, for example, the Wi-Fi module is adjusted to be in a dormant mode, so that the power supply current to the screen module is reduced, the brightness of the screen is reduced, and the power supply to the GPU module is disconnected. And the mobile phone calculates a weighted value according to the first power consumption '800 mW' and the second power consumption '400 mW' corresponding to the call application. Taking the example that the weight value of the first power consumption is 0.6 and the weight value of the second power consumption is 0.4, the weight value of the first power consumption and the second power consumption is 640mW, and the mobile phone reduces the charging power in advance according to 640 mW. For example: the mobile phone predicts that the battery temperature of the mobile phone will be increased by 1.5 ℃ according to the weighted value of the first power consumption and the second power consumption of 640mW, and reduces the charging power by reducing the charging power, so that the current charging power is reduced to 15W by 20W.

In the embodiment of the application, the electronic equipment can effectively avoid the extra power consumption of the battery generated by irrelevant applications and modules and reduce the charging heat generation by limiting the applications and modules which are not related to the call application and reducing the charging power, thereby effectively controlling the temperature rise of the battery and further effectively controlling the battery temperature of the electronic equipment. Meanwhile, when the electronic equipment adjusts the charging power, the charging power to be used is determined by combining the first power consumption and the second power consumption, and the obtained charging power is determined to be integrated with the historical power consumption and the current actual power consumption of the first application, so that the reliability is higher, and the battery temperature can be controlled accurately.
