Disclosure of Invention

The embodiment of the application provides a charging method and electronic equipment, which are used for solving the problem that a user charges the electronic equipment and heats the body of the electronic equipment when the user uses the electronic equipment.

In a first aspect, an embodiment of the present application provides a charging method, including: during charging of the electronic device, judging whether the user is using the electronic device; if the user is using the electronic equipment, judging whether the temperature of the electronic equipment is higher than a first threshold value, wherein the first threshold value is determined according to the human body temperature, and the first threshold value is lower than the human body temperature; if the temperature of the electronic device is above the first threshold, the charging current of the electronic device is reduced to a first target value.

According to the charging method provided by the embodiment of the application, when the electronic equipment is charged, if the fact that the user is using the electronic equipment is detected, and the temperature of the electronic equipment is higher than the first threshold value, the charging current can be reduced, the heat generated by the electronic equipment due to charging is reduced, and the temperature of the electronic equipment is reduced. Therefore, the user can not feel that the electronic equipment heats or scalds the hand, and the use experience of the user is improved.

In one implementation, the method further comprises: if the temperature of the electronic equipment is lower than or equal to a first threshold value, periodically acquiring the temperature and charging current of the electronic equipment at preset sampling intervals; after the temperature and the charging current of the electronic equipment are collected each time, judging whether the temperature of the electronic equipment is higher than a second threshold value, wherein the second threshold value is smaller than the first threshold value; if the temperature of the electronic device is above the second threshold, reducing the charging current of the electronic device according to a first strategy, the first strategy comprising reducing the charging current of the electronic device by a preset factor. Thus, when the electronic device is charged, if the electronic device is detected to be used by a user, and the temperature of the electronic device is lower than the first threshold value and higher than the second threshold value, the charging current can be gradually reduced along with the rise of the temperature, so that the rising trend of the temperature of the electronic device is slowed down until the temperature of the electronic device is no longer increased.

When the temperature of the electronic device falls below the third threshold value, which means that the temperature of the electronic device has been effectively controlled, the risk of heating of the electronic device has been eliminated, in which case the electronic device increases the charging current, which may increase the charging speed.

In one implementation, after increasing the charging current of the electronic device according to the second policy, further comprising: periodically collecting the temperature of the electronic equipment at preset sampling intervals; after the temperature of the electronic equipment is collected each time, judging whether the temperature of the electronic equipment is increased; if the temperature of the electronic device does not rise, increasing the charging current of the electronic device according to a second strategy. Therefore, after the charging current is limited to the first threshold value by the electronic equipment, if the temperature is reduced to be lower than the third threshold value, the charging current can be gradually increased on the premise of ensuring that the temperature is not increased, so that the charging speed is improved, and the use experience of a user is improved.

In one implementation, determining whether a user is using an electronic device includes: judging whether the electronic equipment has jitter in a first time period; if the electronic equipment is in shake, judging whether a display screen of the electronic equipment is in a bright screen state or not; if the display screen is in a bright screen state, judging whether the display screen is shielded; if the display screen is not shielded, judging whether the electronic equipment monitors the input event in a first time period; if an input event is monitored, it is determined that the user is using the electronic device.

The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The following describes exemplary steps of the charging method provided in the embodiment of the present application.

Fig. 3 is an exemplary flowchart of a charging method according to an embodiment of the present application.

As shown in fig. 3, the charging method may specifically include the following steps S101 to S103:

step S101, during charging of the electronic device, it is determined whether the user is using the electronic device.

The electronic device can be charged in a wired or wireless charging mode. If the electronic device adopts a wired charging mode, when a user inserts a data line connected with the power adapter into a USB interface of the electronic device, the charging management module detects that current input can be detected, and at the moment, the electronic device can determine that the electronic device enters a charging state. If the electronic equipment adopts a wireless charging mode, when a user places the electronic equipment on a wireless charger, a wireless charging coil of the electronic equipment can generate current under electromagnetic induction of the wireless charger, so that the charging management module can detect that current input exists, and at the moment, the electronic equipment can determine that the electronic equipment enters a charging state.

In the embodiment of the application, the electronic device may determine whether the user is using the electronic device based on one or more of sensor data, a bright screen or a dark screen state of the display screen, a Top active window activity in the operating system, an input event of the operating system, and the like.

In one implementation, the electronic device may determine, based on the data from the motion sensor, whether the electronic device has changed orientation within a first time period. If no change in orientation is produced, the electronic device may determine that the user is not using the electronic device. If a change in orientation occurs, the electronic device may further determine if the user is using the electronic device in conjunction with other information. The first duration may be a duration before the current time, for example, may be 1 minute, 2 minutes, 3 minutes, and so on; the data of the motion sensor may be, for example, data of a gyroscope, data of a geomagnetic sensor, data of an acceleration sensor, or the like; the orientation change may include, for example, a position change and/or an angle change, neither of which is limiting in the embodiments of the present application.

It will be appreciated that during use of the electronic device by a user, changes in orientation of the electronic device are typically due to hand movements of the user while holding the electronic device, such as shaking of the user's hand or changes in holding posture, which is typically a shake of the electronic device over a small range.

For example, the electronic device may determine whether the electronic device generates an angle change according to data of the gyro sensor or data of the geomagnetic sensor within the first time period. If no angle change is produced, the electronic device may determine that the user is not using the electronic device. If an angle change occurs, the electronic device may further determine if the user is using the electronic device in combination with other information.

For example, the electronic device may determine whether the electronic device generates a position change according to the data of the acceleration sensor in the first period. If no change in location is produced, the electronic device may determine that the user is not using the electronic device. If a change in location occurs, the electronic device may further determine if the user is using the electronic device in conjunction with other information.

In one implementation, the electronic device may determine whether the user is using the electronic device according to a bright or a dark state of the display screen. If the display screen is in an off state, the electronic device may determine that the user is not using the electronic device. If the display screen is in a bright screen state, the electronic device can further judge whether the user is using the electronic device or not in combination with other information.

In one implementation, an electronic device may determine whether an input event is monitored within a first time period. If an input event is monitored, the electronic device may determine that the user is using the electronic device. If no input event is monitored, the electronic device may further determine if the user is using the electronic device in conjunction with other information.

In one implementation, the electronic device may determine whether the user is using the electronic device based on whether it is playing video. If a video is being played, the electronic device may determine that the user is using the electronic device. If the video is not currently played, the electronic device may further determine whether the user is using the electronic device in conjunction with other information.

In one implementation, the electronic device may determine whether the display screen is occluded based on the data of the proximity sensor. If the display screen is occluded, the electronic device may determine that the user is not using the electronic device. If the display screen is not occluded, the electronic device can further determine if the user is using the electronic device in combination with other information.

Step S102, if the user is using the electronic device, it is determined whether the temperature of the electronic device is higher than a first threshold.

The electronic device can determine the temperature of the electronic device according to the data acquired by the temperature sensor.

It should be noted that, some electronic devices include a plurality of temperature sensors to monitor temperatures at different locations or different components. In this case, the electronic device may acquire data measured by the respective temperature sensors and use the highest temperature measured by the respective temperature sensors as the temperature of the electronic device. Alternatively, the electronic device may determine the temperature of the electronic device by measuring the temperature of a target temperature sensor, which may be, for example, a temperature sensor near a center of the electronic device, a temperature sensor near a rear cover of the electronic device, a temperature sensor near a battery of the electronic device, a temperature sensor near a processor of the electronic device, or the like, which is not limited in the embodiment of the present application.

Wherein the first threshold may be determined from the body temperature, preferably below and near the body temperature. In this way, when the temperature of the electronic device reaches the first threshold, the user does not feel warm or scalding when holding the electronic device. The value of the first threshold may be, for example, 30 degrees celsius (hereinafter abbreviated as "degrees") to 36 degrees, and preferably 35 degrees. The specific value of the first threshold is not specifically limited in the embodiment of the present application.

Step S103, if the temperature of the electronic device is higher than the first threshold, reducing the charging current of the electronic device to a first target value.

In a scenario where a user uses an electronic device while charging the electronic device, heat generated by the electronic device is mainly composed of two parts. The first part of heat is heat generated by a processor, a display screen and other devices in the use process of the electronic equipment. The second part of heat is generated by devices such as a battery, a charge management module and the like of the electronic equipment when charging current flows through the devices. Wherein the second portion of the amount of heat is related to the magnitude of the charging current; the larger the charging current is, the larger the generated heat is, and the temperature of the electronic equipment is more easily increased; the smaller the charging current, the less heat is generated, and the less likely the temperature of the electronic device is raised.

If the temperature of the electronic device is above a first threshold, such as above 35 degrees, it is indicated that the temperature of the electronic device has approached or exceeded the body temperature of the human body. At this time, if the temperature of the electronic device continues to rise, the user can feel that the body of the electronic device heats up and even burns hands, and the use experience of the user is affected. In this case, the electronic device reduces the charging current, and the heat generated by the charging can be reduced, reducing the temperature of the electronic device.

In one implementation, the first target value may be a preset value, which may be determined by a technician based on test results or experience, for example: 100mA (milliamp), 200mA, etc., which are not limiting in this embodiment of the present application. When the charging current of the electronic device is the first target value, the electronic device enters a state similar to trickle charging, so that the heat generated by charging is little, the electronic device can timely diffuse the heat into the environment by virtue of the heat dissipation capability of the electronic device, and the temperature of the electronic device can be gradually reduced.

In one implementation, the electronic device may also determine a first target value based on its own heat dissipation capability and real-time power consumption, for example: when the charging current of the electronic equipment is the first target value, the sum of the heat generated by charging the electronic equipment and the real-time power consumption is smaller than the heat dissipation capacity of the electronic equipment. Thus, the higher the real-time power consumption of the electronic device, the smaller the first target value; the lower the real-time power consumption of the electronic device, the greater the first target value. Therefore, the first target value can be flexibly adjusted under the condition of reducing the temperature of the electronic equipment.

According to the charging method provided by the embodiment of the application, when the electronic equipment is charged, if the fact that the user is using the electronic equipment is detected, and the temperature of the electronic equipment is close to the body temperature of a human body, for example, is higher than a first threshold, the charging current can be reduced, the heat generated by charging the electronic equipment is reduced, and the temperature of the electronic equipment is reduced. Therefore, the user can not feel that the electronic equipment heats or scalds the hand, and the use experience of the user is improved.

Fig. 4 is another exemplary flowchart of a charging method provided in an embodiment of the present application.

As shown in fig. 4, the method may further include the following steps after step S102:

step S104, if the temperature of the electronic device is lower than or equal to the first threshold value, periodically collecting the temperature and the charging current of the electronic device at preset sampling intervals.

In a specific implementation, the sampling interval may be a few seconds, for example: 10 seconds, 20 seconds, 30 seconds, 40 seconds, etc., and may be several minutes, for example: 1 minute, 2 minutes, 3 minutes, etc., which are not limited in the examples herein.

Taking a sampling interval of 30 seconds, a first threshold of 35 degrees as an example. If the temperature of the electronic device is lower than or equal to 35 ℃, the electronic device can sample the data measured by the temperature sensor once every 30 seconds to obtain the temperature of the electronic device at each sampling moment, and the temperature at each sampling moment is counted. In addition, the electronic device can sample the charging current once every 30 seconds to obtain the charging current of the electronic device at each sampling time, and count the charging current at each sampling time.

Step S105, after each acquisition of the temperature and the charging current of the electronic device, determining whether the temperature of the electronic device is higher than a second threshold.

Wherein the second threshold is less than the first threshold. The second threshold value may be, for example, in the range of 20 degrees to 30 degrees, preferably 25 degrees. The specific value of the second threshold is not specifically limited in the embodiment of the present application.

In this embodiment of the present application, the second threshold may be used as a risk value for heating of the electronic device. When the temperature of the electronic device is higher than the second threshold but smaller than the first threshold, the user does not feel heat generation of the electronic device. However, if the charging current of the electronic device is large, the temperature of the electronic device may continuously rise on the basis of the second threshold, and there is a risk of heat generation.

Step S106, if the temperature of the electronic device is higher than the second threshold, reducing the charging current of the electronic device according to the first strategy.

In order to avoid the temperature of the electronic equipment from continuously rising on the basis of the second threshold, the heating risk of the electronic equipment is eliminated, and when the temperature of the electronic equipment is higher than the second threshold, the electronic equipment reduces the charging current according to the first strategy so as to reduce the heat generated by charging. The first strategy may include a manner of reducing the charging current by the electronic device each time, including but not limited to reducing the charging current by a preset multiple, or reducing the charging current according to a preset current-temperature curve, etc. Wherein, the reducing the charging current by a preset multiple may include, for example: the embodiment of the present application is not limited to reducing the charging current by 50% (i.e., by half), reducing the charging current by 30%, reducing the charging current by 40%, reducing the charging current by 70%, etc.

Step S107, reducing the charging current of the electronic device according to the first strategy every time the temperature of the electronic device increases by a target degree.

If the temperature of the electronic device continues to rise, which means that the electronic device still does not eliminate the heat risk, then the charging current is reduced once more according to the first strategy every time the temperature of the electronic device rises by a target degree until the temperature of the electronic device does not rise any more. The target degree may be, for example, 0.5 degrees, 1 degree, 2 degrees, 3 degrees, or the like, which is not limited in the embodiment of the present application.

Step S108, if the temperature of the electronic device increases to the first threshold value, reducing the charging current of the electronic device to the first target value.

If the temperature of the electronic device rises to the first threshold value, it is indicated that the heating value of the electronic device is relatively large, so that the temperature of the electronic device cannot be controlled below the first threshold value in the manner of reducing the charging current in steps S106 and S107. In this case, the electronic apparatus may directly reduce the charging current to the first target value, thereby further reducing the heat generation amount of the electronic apparatus and gradually lowering the temperature of the electronic apparatus.

Step S108 is similar to step S103, so that the content of step S108 that is not specifically developed is implemented with reference to step S103, and will not be described here again.

The implementation process of steps S105 to S108 will be further described below by taking the example that the first threshold is 35 degrees, the second threshold is 25 degrees, the first target value is 100mA, the first strategy is to reduce the charging current by 50% each time, the target degree is 1 degree, the temperature of the electronic device acquired in step S104 is 31 degrees, and the charging current is 6A.

Since the temperature of the electronic device is higher than 25 degrees, the electronic device may first reduce the charging current from 6A by 50% to 3A; thereafter, if the temperature of the electronic device increases to 32 degrees, the electronic device may reduce the charging current by 50% to 1.5A; thereafter, if the temperature of the electronic device increases to 33 degrees, the electronic device may decrease the charging current by 50% to 750mA; thereafter, if the temperature of the electronic device increases to 34 degrees, the electronic device may reduce the charging current by 50% to 375mA; thereafter, if the temperature of the electronic device increases to 35 degrees, the electronic device may reduce the charging current to 100mA.

According to the method provided by the embodiment of the application, when the electronic equipment is charged, if the fact that the user is using the electronic equipment is detected, and the temperature of the electronic equipment is lower than the first threshold value and higher than the second threshold value, the charging current can be gradually reduced along with the increase of the temperature, so that the increasing trend of the temperature of the electronic equipment is slowed down until the temperature of the electronic equipment is not increased. Therefore, the user can not feel that the electronic equipment heats or scalds the hand, and the use experience of the user is improved.

Fig. 5 is a further exemplary flowchart of a charging method provided in an embodiment of the present application.

As shown in fig. 5, the method may further include the following steps after step S103 or step S108:

in step S109, it is determined whether the temperature of the electronic device is lower than a third threshold.

Wherein the third threshold is less than the first threshold. For example, when the first threshold is 35 degrees, the third threshold may be any value less than 35 degrees, such as 20 degrees, 25 degrees, 27 degrees, 29 degrees, 30 degrees, 31 degrees, 32 degrees, and the like, which is not limited in the embodiment of the present application.

In one implementation, the third threshold is preferably less than the first threshold and greater than the second threshold. For example, when the first threshold is 35 degrees and the second threshold is 25 degrees, the third threshold may be any value less than 35 degrees and greater than 25 degrees, such as: 26 degrees, 28 degrees, 30 degrees, etc., which are not limited in this embodiment.

It is understood that the electronic device after performing step S103 or S108, the charging current is limited to a small first target value, for example, 100mA, and the amount of heat generated by charging is small. In this case, the temperature of the electronic device drops rapidly as long as the device such as the processor of the electronic device does not generate much heat due to high load operation (e.g., the electronic device does not operate a large 3D game or does not operate performance test software). When the temperature of the electronic device falls below the third threshold, it is indicated that the temperature of the electronic device has been effectively controlled and the risk of heating of the electronic device has been eliminated.

Step S110, if the temperature of the electronic device is lower than the third threshold, increasing the charging current of the electronic device according to the second policy.

The second strategy may include a manner of increasing the charging current by the electronic device each time, including but not limited to increasing the charging current by a preset multiple, or increasing the charging current according to a preset current-temperature curve, etc. Wherein, increasing the charging current by a preset multiple may include, for example: the embodiment of the present application is not limited to this, and the charging current is increased by 100% (i.e., by one time), by 50% (i.e., by one half), by 200% (i.e., by two times), by 300% (i.e., by three times), and so on.

For example, when the third threshold is 30 degrees, the second strategy is to double the charging current, and the first target value is 100mA, if the temperature of the electronic device is lower than 30 degrees, the electronic device may double the charging current from 100mA to 200mA.

Step S111, periodically collecting the temperature of the electronic device at preset sampling intervals.

The sampling interval in step S111 may be the same as or different from the sampling interval in step S104.

Taking the sampling interval of 30 seconds as an example, the electronic device can sample the data of the temperature sensor once every 30 seconds to obtain the temperature of the electronic device at each sampling moment, and count the temperature at each sampling moment.

Step S112, after each time the temperature of the electronic device is collected, judging whether the temperature of the electronic device is increased.

In a specific implementation, the electronic device may compare the temperature obtained by sampling at the current time with the temperature obtained by sampling at the last sampling time. If the temperature sampled at the current time is higher than the temperature sampled at the last sampling time, the temperature of the electronic device is indicated to be increased. If the temperature sampled at the current time is lower than or equal to the temperature sampled at the last sampling time, the temperature of the electronic device is not increased.

Step S113, if the temperature of the electronic device does not rise, increasing the charging current of the electronic device according to the second strategy.

If the temperature of the electronic device is not increased, the current charging current does not cause the electronic device to generate heat, so the electronic device can increase the charging current according to the second strategy to increase the charging speed. Taking the second strategy as an example of doubling the charging current and taking the current charging current as 200mA, if the temperature of the electronic equipment is not increased, the electronic equipment can doubled the charging current from 200mA to 400mA; at the next sampling moment, if the temperature of the electronic equipment is still not increased, the electronic equipment can increase the charging current by one time from 400mA to 800mA; at the next sampling moment, if the temperature of the electronic equipment is not increased still, the electronic equipment can increase the charging current from 800mA to 1.2A by one time; and so on.

If the temperature of the electronic device increases, the electronic device does not continue to increase the current and monitors whether its temperature increases to a first threshold. If the temperature of the electronic device rises to the first threshold value, the charging current is reduced to the first target value, i.e., step S108 is performed.

According to the method provided by the embodiment of the application, after the charging current is limited to the first threshold value by the electronic equipment, if the temperature is reduced to be lower than the third threshold value, the charging current can be gradually increased on the premise of ensuring that the temperature is not increased, so that the charging speed is improved, and the user experience is improved.

Fig. 6 is a flowchart of step S101 of a charging method provided in an embodiment of the present application.

As shown in fig. 6, in one implementation, step S101 may specifically include the following steps S201-S209. When the electronic device runs the Android system, the following steps can be executed by a battery management application running in the Android system.

Step S201, motion sensor data in a first duration is acquired.

In particular implementations, the battery management application may invoke a registration listening register interface of the sensor manager to register sensors to be listened to with the sensor manager, including but not limited to one or more of a motion sensor, a proximity light sensor, a temperature sensor. After this, the battery management application may invoke the onSensorChanged interface of the sensor manager to obtain motion sensor data for a first duration. The first period may be, for example, 1 minute, 2 minutes, 3 minutes, or the like, which is not limited in the embodiment of the present application.

Step S202, monitoring input events in a first duration.

In a specific implementation, the battery management application may invoke a register input device listening for register input manager interface of the input manager to register for listening for input events with the input manager. After this, the input manager may report the input event to the battery management application if the input event is detected. Wherein the input event includes, but is not limited to: an event that a user performs a click input on a display screen of the electronic device, an event that a slide input is performed, an event that a user presses a physical key of the electronic device, and the like.

In step S203, proximity sensor data is acquired.

In a specific implementation, the battery management application may invoke the onSensorChanged interface of the sensor manager to obtain the proximity sensor data.

Step S204, monitoring the bright screen state or the extinguished screen state of the display screen.

In a specific implementation, the battery management application may determine the state of charge or the off state of the display by listening to a display state broadcast of the system. For example: if the broadcasting intent of the display SCREEN ON is monitored, the display SCREEN can be determined to be in a bright SCREEN state, and if the broadcasting intent of the display SCREEN OFF is monitored, the display SCREEN can be determined to be in a extinguished state.

The order of steps S201 to S204 is not limited in the embodiment of the present application. In some other implementations, steps S201 to S204 may be performed simultaneously or in other orders, which do not exceed the protection scope of the embodiments of the present application.

In step S205, it is determined whether the electronic device has jitter in the first period according to the motion sensor data.

If the electronic device has jitter, step S206 is performed.

If the electronic device does not have jitter, it is determined that the user is not using the electronic device.

For example, the battery management application may determine whether the electronic device has an angle change during the first period of time based on data from the gyro sensor or data from the geomagnetic sensor. If an angular change is produced, it may be determined that the electronic device is jittered. If no angle change occurs, it can be determined that the electronic device is free from shake, and the user is not using the electronic device.

For example, the battery management application may determine whether the electronic device has a position change within the first time period based on the data from the acceleration sensor. If a change in position occurs, it may be determined that the electronic device is jittered. If no change in position occurs, it may be determined that the electronic device is not subject to jitter and the user is not using the electronic device.

Step S206, judging whether the display screen of the electronic device is in a bright screen state.

If the display screen of the electronic device is in the bright screen state, step S207 is performed.

If the display screen of the electronic device is not in the bright screen state, determining that the user does not use the electronic device.

Step S207, judging whether the display screen is blocked or not according to the data of the proximity light sensor.

If the display screen is not occluded, step S208 is performed.

If the display screen is occluded, it is determined that the user is not using the electronic device.

In particular implementations, if the proximity light sensor detects that an object is present in front of the display screen and the distance of the object from the display screen is less than a preset distance threshold, the battery management application may determine that the display screen is occluded.

In step S208, it is determined whether the electronic device monitors the input event within the first period.

If no input event is monitored, step S209 is performed.

If an input event is monitored, it is determined that the user is using the electronic device.

Step S209, determines whether an application program interface of the electronic device for playing the video stream is called.

If the application program interface for playing the video stream is not called, determining that the user does not use the electronic device.

If an application program interface for playing the video stream is invoked, it is determined that the user is using the electronic device.

In particular implementations, the battery management application may call the isplay () method in the media player MediaPlayer to determine whether the electronic device is playing video. If the isplay () method returns a value true, it is stated that an application program interface for playing a video stream is called, and the electronic device is playing a video, so it can be determined that the user is using the electronic device. If the isplay () method returns a false value, it is indicated that the application program interface for playing the video stream is not called, the electronic device does not play the video, and thus it can be determined that the user does not use the electronic device.

The order of steps S205 to S209 is not limited in the embodiment of the present application. In some other implementations, steps S205 to S209 may be performed in other orders, which do not exceed the protection scope of the embodiments of the present application.

The method provided by the embodiment of the application can judge whether the user is using the electronic equipment or not only by using the interfaces and the methods of the common sensor device and the operating system, and does not need to use a front camera, a dot matrix projector, a floodlight sensing element and other specific devices, is easy to realize, and does not increase additional power consumption.

In some implementations, the electronic device may also determine whether the user is using the electronic device based on one or more front-facing cameras and/or one or more front-facing sensors. For example: and carrying out face recognition on the image shot by the front camera by utilizing a face recognition algorithm, and if the face can be recognized all the time in a period of time and the face is always oriented to the display screen, determining that the user is using the electronic equipment.

In addition, in a scenario where a user uses an electronic device while charging the electronic device, the electronic device learns the usage habits of the user using an artificial intelligence algorithm, for example: the electronic device may learn the user's time preference to charge the electronic device, learn the user's preference to use applications during the charging of the electronic device, learn the effects of the execution of the respective applications on the temperature change of the electronic device, and so on. In this way, the electronic device may optimize the charging method provided in the embodiment of the present application according to the learning result, for example, optimize one or more parameters of the first threshold, the second threshold, the third threshold, the first target value, the first duration, and the sampling interval.

In the embodiments provided in the present application, the schemes of the charging method provided in the present application are described from the perspective of the electronic device itself and the interaction between the electronic device and the user. It will be appreciated that the electronic device, in order to achieve the above-described functions, includes corresponding hardware structures and/or software modules that perform the respective functions. Those of skill in the art will readily appreciate that the elements and algorithm steps of the examples described in connection with the embodiments disclosed herein may be implemented as hardware or combinations of hardware and computer software. Whether a function is implemented as hardware or computer software driven hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

Fig. 7 is a schematic structural diagram of a charging device according to an embodiment of the present application.

In some embodiments, the electronic device may implement the corresponding functions by the hardware apparatus shown in fig. 7. As shown in fig. 7, the charging device may include: a memory 701 and a processor 702.

In one implementation, the processor 702 may include one or more processing units, such as: the processor 702 may include an application processor, a controller, a video codec, a digital signal processor, and/or a neural network processor, etc. Wherein the different processing units may be separate devices or may be integrated in one or more processors. The memory 701 is coupled to the processor 702 for storing various software programs and/or sets of instructions. In some embodiments, memory 701 may include volatile memory and/or non-volatile memory.

In one embodiment, the software program and/or sets of instructions in the memory 701, when executed by the processor 702, cause the electronic device to perform the method steps of: during charging of the electronic device, judging whether the user is using the electronic device; if the user is using the electronic equipment, judging whether the temperature of the electronic equipment is higher than a first threshold value, wherein the first threshold value is determined according to the human body temperature, and the first threshold value is lower than the human body temperature; if the temperature of the electronic device is above the first threshold, the charging current of the electronic device is reduced to a first target value. Thus, when the electronic equipment is charged, if the fact that the user is using the electronic equipment is detected, and the temperature of the electronic equipment is higher than the first threshold value, the charging current can be reduced, heat generated by charging of the electronic equipment is reduced, and the temperature of the electronic equipment is reduced. Therefore, the user can not feel that the electronic equipment heats or scalds the hand, and the use experience of the user is improved.

In one embodiment, the software programs and/or sets of instructions in the memory 701, when executed by the processor 702, further cause the electronic device to perform the method steps of: if the temperature of the electronic equipment is lower than or equal to a first threshold value, periodically acquiring the temperature and charging current of the electronic equipment at preset sampling intervals; after the temperature and the charging current of the electronic equipment are collected each time, judging whether the temperature of the electronic equipment is higher than a second threshold value, wherein the second threshold value is smaller than the first threshold value; if the temperature of the electronic device is above the second threshold, reducing the charging current of the electronic device according to a first strategy, the first strategy comprising reducing the charging current of the electronic device by a preset factor. Thus, when the electronic device is charged, if the electronic device is detected to be used by a user, and the temperature of the electronic device is lower than the first threshold value and higher than the second threshold value, the charging current can be gradually reduced along with the rise of the temperature, so that the rising trend of the temperature of the electronic device is slowed down until the temperature of the electronic device is no longer increased. Therefore, the user can not feel that the electronic equipment heats or scalds the hand, and the use experience of the user is improved.

In one embodiment, the software programs and/or sets of instructions in the memory 701, when executed by the processor 702, further cause the electronic device to perform the method steps of: when the temperature of the electronic equipment is increased by a target degree, reducing the charging current of the electronic equipment according to a first strategy; if the temperature of the electronic device increases to a first threshold value, the charging current of the electronic device is reduced to a first target value. In this way, if the heating value is large during charging of the electronic device, the charging current can be directly reduced to the first target value, so that the heating value of the electronic device is further reduced, and the temperature of the electronic device is gradually reduced.
