Charging method and charging device

Technical Field

Background

Along with the function of the mobile terminal is more and more abundant, the power consumption of the mobile terminal is more and more large, and therefore the cruising ability of the terminal is seriously affected. In order to solve the problem of large power consumption of the terminal, two technical schemes are mainly adopted at present: one is to perform power saving management on each application in the terminal, avoid unnecessary power consumption of the application and reduce power consumption; another is to increase the battery capacity so that more power can be stored.

At present, the battery capacity of the mobile terminal is higher and higher, and if the traditional charging mode is continuously adopted, the time for fully charging the battery is long. For this reason, a fast charging scheme (fast charging for short) is proposed in the prior art, and fast charging is to use a higher charging power for charging.

Although the charging speed of the quick charging is high, the terminal generates a large amount of heat because the charging power is high.

In the embodiment of the present invention, the target application is an application specified in advance by a manufacturer or a user, and is usually an application that causes serious terminal heating during running, and the user can increase or decrease the target application as needed.

In the embodiment of the present invention, the preventing of the terminal from generating heat does not mean that the terminal does not generate heat, but means that the temperature of the terminal reaches a level that is difficult to be tolerated by a user, so that the user may complain. That is, the heat generated from the terminal is prevented to the extent that complaints are generated from the user.

Example one

Referring to fig. 1, a charging method according to a first embodiment of the present invention is provided. In the embodiment of the present invention, the second charging policy may be understood as a normal charging manner in the prior art, such as fast charging, normal charging, and the like. The embodiment of the invention adds the first charging strategy on the basis of the prior art, the charging power corresponding to the first charging strategy is smaller than the charging power of the second charging power, and the charging speed and the use experience of a user are balanced by flexibly switching between the first charging strategy and the second charging strategy. The charging method comprises the following steps:

and S11, monitoring the running state of the target application program in the terminal in the charging process. Judging whether the target application program is in a running state, and when the target application program is in the running state, entering the step S12; when the target application is in the non-running state, the process proceeds to step S13.

Specifically, after the charging interface of the terminal is detected to be connected with the charger and enter a charging state, the running state of the target application program in the terminal starts to be monitored. The target application may include one or at least two of a call application, a game application, a video application, a navigation application, a camera application, and the like that cause severe heat generation of the terminal when running. Further, the user may designate any application as a target application as desired.

Alternatively, two states, a first state and a second state, may be set for the target application. Monitoring a state switching event of a target application program in a charging process; when the target application program is switched to a first state, determining that the target application program is in a running state; and when the target application program is switched to the second state, determining that the target application program is in the non-running state. The monitoring mode is low in energy consumption, and the running state of the target application program can be detected in real time.

One skilled in the art will appreciate that other ways of monitoring the operational status of the target application may be used. For example, real-time detection of whether a target application is currently running is performed, but this approach is energy intensive. For another example, it is detected regularly whether the target application is currently running, but this method has poor real-time performance, i.e. the running state of the target application cannot be detected in time.

And S12, executing a first charging strategy. In the embodiment of the invention, when the target application program is monitored to be in the running state, the normal charging mode is changed, and the first charging strategy is executed, so that the problem of serious heating of the terminal caused by the running of the target application program is solved.

Optionally, the following first charging strategy may be adopted: the charging power is directly limited to a first preset level so as to reduce the charging power and reduce the heat productivity. For example, assuming that the normal charging power is 20W, when the target application is in the running state, the charging power is limited to 15W

The corresponding first predetermined level may be the same or different for different target applications, i.e. the charging power may be reduced to the same level or to different levels when different target applications are running. According to experiments, corresponding power levels can be set for different target applications, a lower power level can be set for an application with a high heating value, and a higher power level can be set for the application with a high heating value.

Optionally, the following charging strategy may also be adopted: and detecting the temperature of the terminal, and reducing the charging power when the temperature of the terminal is greater than a first threshold value. This will be described in detail later.

Of course, those skilled in the art will understand that other charging strategies in the prior art may be adopted to alleviate the heating problem, which is not described herein.

And S13, executing a second charging strategy.

And when the target application program is in the non-running state, executing a second charging strategy.

Alternatively, when the second charging strategy is implemented, the charging power may be directly increased to a second predetermined level, and the charging speed may be ensured by full-speed charging.

Optionally, when the second charging strategy is executed, the temperature of the terminal is detected, and the charging power is gradually increased to a second predetermined level as the temperature of the terminal decreases. Thereby preventing a sudden temperature rise due to an instantaneous increase in charging power.

Of course, in embodiments of the present invention, the second predetermined level is higher than the first predetermined level.

In step S12, a first charging strategy as shown in fig. 2 may be performed, including the steps of:

and S121, detecting the temperature of the terminal. And judging whether the temperature of the terminal is greater than a first threshold value, and executing the step S122 when the temperature is greater than the first threshold value.

Specifically, when the target application program is monitored to be in the running state, the temperature of the designated part of the terminal is detected in real time or periodically by the temperature sensor. The designated portion is generally a portion which generates heat seriously or is sensitive to temperature of a user, and of course, any portion may be designated as required.

Alternatively, a temperature sensor may be provided at any one of a battery, a screen, a Central Processing Unit (CPU), a Power Management Unit (PMU), a Graphic Processing Unit (GPU) and the like of the terminal, and the temperature of the any one of the parts may be detected by the temperature sensor.

Alternatively, temperature sensors may be disposed at least at two of the battery, the screen, the central processing unit, the power management unit, the graphic processor, and the like of the terminal, and the temperatures of the at least two parts may be detected by the temperature sensors.

Further, different temperature detection sites may be designated for different target applications. For example, when a call application is running, the temperature of the screen is mainly detected because the screen is in contact with the face when the user makes a call and is therefore most sensitive to the temperature of the screen; meanwhile, the battery part of the rear cover of the terminal is held by hands, so that the temperature of the battery can be detected. As another example, when a game application or a video application is running, the temperature of the central processor and/or the graphics processor is mainly detected, because the game and the video need to consume a lot of resources of the central processor and the graphics processor, resulting in that these two devices generate a lot of heat.

It can be understood by those skilled in the art that, in addition to using the temperature sensor to detect the temperature of the terminal, other methods in the prior art can be used to detect the temperature of the terminal, and are not described herein.

In the charging process, when the temperature of the terminal exceeds a certain value, a user feels uncomfortable and affects user experience, and the temperature of the terminal can be reduced by reducing charging power. The first threshold value may be determined according to actual needs and experimental results, and for example, the first threshold value may be set to 40 ℃.

The first thresholds corresponding to different portions of the terminal may be the same or different. For locations where the user is more sensitive to temperature, the first threshold may be set lower, while for locations where the user is less sensitive to temperature, the first threshold may be set higher. For example, the screen is a part directly contacted by a human face and is sensitive to temperature, so that the first threshold corresponding to the screen can be set to be 37 ℃; the parts such as the battery central processing unit, the power management unit, the graphic processor and the like are parts indirectly contacted by human hands, and have stronger tolerance to temperature, so that the first threshold corresponding to the parts can be set to be 40 ℃.

And after the temperature of the terminal is detected, comparing the detected temperature with the first threshold value, judging whether the temperature is greater than the first threshold value, and if so, entering the next step S122.

And S122, reducing the charging power.

Specifically, when it is detected that the temperature of the terminal is greater than the first threshold, it is indicated that the temperature is too high, and in order to prevent the user experience from being affected by the too high temperature, the charging power is reduced to reduce the temperature of the terminal. Specifically, the reduction of the charging power can be achieved by reducing the charging current or the charging voltage.

When the temperatures of at least two parts of the terminal are detected, reducing the charging power as long as the temperature of any part is greater than a first threshold value; or, when the temperature of the preset number of parts of the terminal is greater than the first threshold, the charging power is reduced. The preset number can be set according to the requirement, such as one, two, three, etc., for example: when the temperature of one part of the terminal is greater than a first threshold value and the temperature of other parts of the terminal is not greater than the first threshold value, the charging power is not reduced; and when the temperature of two or more parts of the terminal is greater than a first threshold value, reducing the charging power.

In some embodiments, the process of the terminal reducing the charging power is: in a power reduction process, when the temperature of the terminal is detected to be greater than a first threshold value for the first time, reducing a charging power set value; and then, with the preset time as a period, detecting the temperature at regular time, and as long as the temperature is still greater than the first threshold, continuing to reduce the charging power until the temperature is less than or equal to the first threshold. In one power reduction process, that is, the whole process from the first time of reducing the charging power to the time of stopping reducing the charging power, one power reduction process may reduce the charging power only once, or may reduce the charging power at least twice.

A specific flow of reducing the charging power of the terminal is shown in fig. 3, and includes the following steps:

s101, detecting that the temperature of the terminal is larger than a first threshold value, and reducing a charging power set value.

In step S101, the charging power is first reduced in a power reduction process, and the value (amplitude) for reducing the charging power may be set according to actual needs, for example, the charging power may be set to be reduced by 2W. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S102, detecting the temperature of the terminal at regular time by taking preset time as a period. Judging whether the temperature of the terminal is still larger than a first threshold value; when the temperature of the terminal is still greater than the first threshold, executing step S103; when the temperature of the terminal is less than or equal to the first threshold, step S104 is performed.

Specifically, after the charging power is reduced, the temperature of the terminal is queried every certain time, and whether the temperature of the terminal changes or not is judged, wherein the temperature is still larger than the first threshold.

And S103, continuously reducing the set value of the charging power. Then, the process returns to step S102 to continue the inquiry about the temperature of the terminal.

And when the temperature of the terminal is still larger than the first threshold value, the charging power is continuously reduced. The value (magnitude) of the charging power reduction may be set according to actual needs, and for example, the charging power reduction 2W may be set. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S104, stopping reducing the charging power.

And when the temperature of the terminal is less than or equal to the first threshold, indicating that the terminal has reduced to a proper temperature, and ending the power reduction process without reducing the charging power.

Therefore, the temperature of the terminal can be just lower than the first threshold value by reducing the charging power gradually, and the situation that the charging power is reduced too much at one time is prevented so as to keep a faster charging speed.

In other embodiments, the process of the terminal reducing the charging power is as follows: in a power reduction process, when the temperature is detected to be greater than a first threshold value for the first time, reducing a charging power set value; and then, detecting the temperature at regular time by taking the preset time as a period, and continuing to reduce the charging power until the temperature is less than or equal to the first threshold or the charging power is less than or equal to the lower limit as long as the temperature is still greater than the first threshold and the current charging power is greater than the lower limit. The power reduction procedure is the same as the power reduction procedure, and is not described herein.

The specific process of reducing the charging power by the terminal is shown in fig. 4, and includes the following steps:

s201, detecting that the temperature of the terminal is larger than a first threshold value, and reducing a charging power set value.

In step S121, the charging power is first reduced in a power reduction process, and the value (amplitude) for reducing the charging power may be set according to actual needs, for example, the charging power may be set to be reduced by 2W. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S202, detecting the temperature of the terminal at regular time by taking preset time as a period. Judging whether the temperature of the terminal is still larger than a first threshold value or not, and simultaneously judging whether the current charging power is larger than a lower limit value or not; when the temperature of the terminal is still greater than the first threshold value and the current charging power is greater than the lower limit value, executing step S203; when the temperature of the terminal is less than or equal to the first threshold or the charging power is less than or equal to the lower limit value, step S204 is performed.

Specifically, after the charging power is reduced, the temperature of the terminal is queried every certain time, and whether the temperature of the terminal changes or not is judged, wherein the temperature is still larger than the first threshold. Meanwhile, in order to prevent the charging power from being too low to affect normal charging and ensure the charging speed, the present embodiment further sets a lower limit value for the charging power, compares the current charging power with the lower limit value, and determines whether the current charging power is greater than the lower limit value.

And S203, continuously reducing the set value of the charging power. Then, the process returns to step S202 to continuously inquire the temperature of the terminal.

And when the temperature of the terminal is still larger than the first threshold value and the current charging power is larger than the lower limit value, continuing to reduce the charging power. The value (magnitude) of the charging power reduction may be set according to actual needs, and for example, the charging power reduction 2W may be set. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S204, stopping reducing the charging power.

When the temperature of the terminal is less than or equal to the first threshold or the charging power is less than or equal to the lower limit, it indicates that the terminal has decreased to a suitable temperature or the charging power has reached the lower limit, the charging power is not decreased, and the power reduction process is ended.

Therefore, the charging speed is prevented from being influenced by too low charging power by setting the lower limit value of the charging power.

Alternatively, in one power reduction flow, when the charging power is reduced at least twice, the value of each reduction of the charging power is equal. For example, the charging power is reduced three times in one power reduction process, and the value of each reduction of the charging power is 2W.

Alternatively, in one power reduction procedure, when the charging power is reduced at least twice, values of the charging power reduced at least twice adjacent to each other are not equal. For example, in a power reduction process, the charging power is reduced three times, the value of the charging power is reduced for the first time and the second time, the value of the charging power is reduced for the second time and the third time, for example, the charging power is reduced for the first time by 2W, and the charging power is reduced for each of the second time and the third time by 1W.

In step S12, a first charging strategy as shown in fig. 5 may also be implemented, including the following steps:

And S122, reducing the charging power.

And S123, judging whether the temperature of the terminal is less than a second threshold value. When the temperature of the terminal is less than the second threshold, step S124 is performed.

The second threshold is set as the lower limit of the temperature to prevent the charging speed from being affected by the too low charging power, and the temperature of the terminal is kept between the first threshold and the second threshold, so that the temperature of the terminal is not too high to affect the user experience, and the charging speed is not reduced by the too low charging power, so that the charging speed and the user experience are both considered.

The second threshold values corresponding to different parts of the terminal may be the same or different, and generally, the second threshold value may be determined according to the first threshold value. For example, the first threshold value and the second threshold value may be set to 37 ℃ and 35 ℃, or 40 ℃ and 38 ℃, respectively, and so on.

And S124, improving the charging power.

Specifically, when it is detected that the temperature of the terminal is less than the second threshold, the charging power is increased in order to increase the charging speed. Specifically, the charging power can be increased by increasing the charging current or the charging voltage.

When the temperatures of at least two parts of the terminal are detected, the charging power is increased as long as the temperature of any part is less than a second threshold value; or when the temperature of the preset number of parts of the terminal is smaller than the second threshold value, the charging power is increased. The preset number can be set according to the requirement, such as one, two, three, etc., for example: when the temperature of one part of the terminal is less than a second threshold value and the temperatures of other parts of the terminal are not less than the second threshold value, the charging power is not increased; and when the temperature of two or more parts of the terminal is less than the second threshold value, the charging power is increased.

In some embodiments, the process of the terminal increasing the charging power is: in a power increasing process, when the temperature of the terminal is detected to be smaller than a second threshold value for the first time, increasing a set value of charging power; and then, with the preset time as a period, detecting the temperature at regular time, and as long as the temperature is still less than the second threshold, continuing to increase the charging power until the temperature is greater than or equal to the second threshold. In one power increasing process, that is, the whole process from the first time of increasing the charging power to the time of stopping increasing the charging power, one power increasing process may only increase the charging power once, and may also increase the charging power at least twice.

A specific flow of the terminal increasing the charging power is shown in fig. 6, and includes the following steps:

and S301, detecting that the temperature of the terminal is smaller than a second threshold value, and increasing the set value of the charging power.

In step S301, the charging power is increased for the first time in a power increasing process, and the value (amplitude) for increasing the charging power may be set according to actual needs, for example, the value for increasing the charging power may be set to 2W. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S302, detecting the temperature of the terminal at regular time by taking preset time as a period. Judging whether the temperature of the terminal is still smaller than a second threshold value; when the temperature of the terminal is still less than the second threshold, executing step S303; when the temperature of the terminal is greater than or equal to the second threshold, step S304 is performed.

Specifically, after the charging power is increased, the temperature of the terminal is queried every certain time, and whether the temperature of the terminal changes or not is judged, wherein the temperature is still smaller than the second threshold. And S303, continuously increasing the set value of the charging power. Then, the process returns to step S302 to continuously inquire the temperature of the terminal.

And when the temperature of the terminal is still less than the second threshold value, the charging power is continuously increased. The value (amplitude) for increasing the charging power may be set according to actual needs, and for example, the charging power 2W may be set. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S304, stopping increasing the charging power.

And when the temperature of the terminal is greater than or equal to the second threshold, indicating that the terminal has reached the appropriate temperature range, not increasing the charging power any more, and ending the power increasing process.

Therefore, the charging power is gradually improved, the temperature of the terminal can stably fall into a proper range, the temperature is prevented from greatly rising, and the charging stability is kept.

In other embodiments, the process of the terminal increasing the charging power is as follows: in a power increasing process, when the temperature is detected to be less than a second threshold value for the first time, increasing the set value of the charging power; and then, with the preset time as a period, detecting the temperature at regular time, and as long as the temperature is still less than the second threshold and the current charging power is less than the upper limit value, continuing to increase the charging power until the temperature is greater than or equal to the second threshold or the charging power is greater than or equal to the upper limit value. The power boosting procedure is the same as the power boosting procedure, and is not described herein.

A specific flow of increasing the charging power by the terminal is shown in fig. 7, and includes the following steps:

s401, when the temperature of the terminal is smaller than a second threshold value, the set value of the charging power is increased.

In step S401, the charging power is increased for the first time in a power increasing process, and the value (amplitude) for increasing the charging power may be set according to actual needs, for example, the value for increasing the charging power may be set to 2W. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

And S402, detecting the temperature of the terminal at regular time by taking preset time as a period. Judging whether the temperature of the terminal is still smaller than a second threshold value or not, and simultaneously judging whether the current charging power is smaller than an upper limit value or not; when the temperature of the terminal is still less than the second threshold and the current charging power is less than the upper limit value, executing step S403; when the temperature of the terminal is greater than or equal to the second threshold or the charging power is greater than or equal to the upper limit value, step S404 is performed.

Specifically, after the charging power is increased, the temperature of the terminal is queried every certain time, and whether the temperature of the terminal changes or not is judged, wherein the temperature is still smaller than the second threshold. Meanwhile, in order to prevent the charging power from being too high to affect the charger, the present embodiment also sets an upper limit value for the charging power, compares the current charging power with the upper limit value, and determines whether the current charging power is smaller than the upper limit value.

And S403, continuously increasing the set value of the charging power. Then, the process returns to step S402 to continuously inquire the temperature of the terminal.

And when the temperature of the terminal is still less than the second threshold value and the current charging power is less than the upper limit value, continuing to increase the charging power. The value (amplitude) of the boost charging power may be set according to actual needs, for example, the boost charging power of 2W may be set. Of course, the amount may be set to 1W, 1.5W, 2.5W, 3W, 4W, etc., without limitation.

S404, stopping reducing the charging power.

When the temperature of the terminal is greater than or equal to the second threshold or the charging power is greater than or equal to the upper limit, it indicates that the terminal has reached the appropriate temperature range or the charging power has reached the upper limit, the charging power is not increased, and the power increasing process is ended.

Therefore, the charging power upper limit value is set, so that the influence of overhigh charging power on the charger is prevented.

Alternatively, in one power increasing flow, when the charging power is increased at least twice, the value of each increase in the charging power is equal. For example, in one power increasing process, the charging power is increased three times, and each time the charging power is increased, the value is 2W.

Optionally, in one power increasing procedure, when the charging power is increased at least twice, values of the charging power increased at least two adjacent times are not equal. For example, in one power increasing process, the charging power is increased three times, the value of the charging power increased for the first time is different from that increased for the second time, and the value of the charging power increased for the second time is the same as that increased for the third time, for example, the charging power is increased for the first time by 2W, and the charging power is increased for each of the second time and the third time by 1W.

Therefore, in the charging method provided by the embodiment of the invention, the use state of the target application program with larger calorific value is monitored in the charging process, when the target application program is detected to be in the running state, the first charging strategy with lower charging power is immediately executed, so that the user experience is prevented from being influenced by serious heating of the terminal, and when the target application program is detected to be in the non-running state, the second charging strategy with higher charging power is executed, so that the charging speed is ensured. Therefore, the use experience of a user is improved in the quick charging process, the charging speed and the use experience of the user are both considered, the satisfaction degree of the user is improved, and the competitiveness of a product is improved.

Example two

Referring to fig. 8, a charging apparatus according to a second embodiment of the present invention is proposed, which includes a monitoring module 10 and a processing module 20, wherein:

the monitoring module 10: the method and the device are used for monitoring the running state of the target application program in the terminal in the charging process. And notifies the processing module of the monitoring result.

Specifically, when it is detected that the charging interface of the terminal is connected to the charger to enter the charging state, the monitoring module 10 starts to monitor the running state of the target application program in the terminal. The target application may include one or at least two of a call application, a game application, a video application, a navigation application, a camera application, and the like that cause severe heat generation of the terminal when running. Further, the user may designate any application as a target application as desired.

Alternatively, two states, a first state and a second state, may be set for the target application. In the charging process, the monitoring module 10 monitors a state switching event of a target application program; when the target application program is switched to a first state, determining that the target application program is in a running state; and when the target application program is switched to the second state, determining that the target application program is in the non-running state. The monitoring mode is low in energy consumption, and the running state of the target application program can be detected in real time.

One skilled in the art will appreciate that other ways of monitoring the operational status of the target application may be used. For example, the monitoring module 10 detects whether the target application is currently running in real time, but this approach is energy intensive. For another example, the monitoring module 10 detects whether the target application is currently running at regular time, but this method has poor real-time performance, i.e. the running state of the target application cannot be detected in time.

The processing module 20: the terminal is used for executing a first charging strategy when the target application program is in a running state so as to reduce the terminal heating; when the target application is in the non-running state, a second charging strategy is executed to guarantee the charging speed. And the charging power corresponding to the second charging strategy is greater than the charging power corresponding to the first charging strategy.

Specifically, when the monitoring module 10 monitors that the target application is in the running state, the processing module 20 executes a first charging strategy with lower charging power, so as to alleviate the problem of serious terminal heating caused by running of the target application. When the monitoring module 10 monitors that the target application is in the non-running state, the processing module 20 executes a second charging strategy with higher charging power, charges at full speed, and ensures the charging speed.

Alternatively, the processing module 20 may assume the following first charging strategy: the charging power is directly limited to a first preset level so as to reduce the charging power and reduce the heat productivity. For example, assuming that the normal charging power is 20W, when the target application is in the running state, the charging power is limited to 15W.

The corresponding first predetermined levels may be the same or different for different target applications, i.e. the processing module 20 may reduce the charging power to the same level or to different levels when different target applications are running. According to experiments, corresponding power levels can be set for different target applications, a lower power level can be set for an application with a high heating value, and a higher power level can be set for the application with a high heating value.

Optionally, the processing module 20 may also adopt the following first charging strategy: and detecting the temperature of the terminal, and reducing the charging power when the temperature of the terminal is greater than a first threshold value. At this time, the processing module includes a temperature detection unit 21 and a power reduction unit 22 as shown in fig. 9, in which:

temperature detection unit 21: for detecting the temperature of the terminal.

The specific temperature detection unit 21 may detect the temperature of the terminal-designated portion in real time or periodically (periodically) by a temperature sensor. The designated portion is generally a portion which generates heat seriously or is sensitive to temperature of a user, and of course, any portion may be designated as required.

Alternatively, a temperature sensor may be provided at any one of a battery, a screen, a central processing unit, a power management unit, a graphic processor, and the like of the terminal, and the temperature detection unit 21 may detect the temperature of any one of the foregoing parts by the temperature sensor.

Alternatively, temperature sensors may be disposed at least at two locations among the battery, the screen, the central processing unit, the power management unit, the graphic processor, and the like of the terminal, and the temperature detection unit 21 may detect the temperatures of the at least two locations through the temperature sensors.

The power reduction unit 22: when the temperature of the terminal is greater than a first threshold, the charging power is reduced.

The power reduction unit 22 compares the detected temperature with a first threshold, and reduces the charging power when the temperature is greater than the first threshold, specifically, the reduction of the charging power may be realized by reducing the charging current or the charging voltage.

When the temperatures of at least two parts of the terminal are detected, the power reduction unit 22 reduces the charging power as long as the temperature of any one part is greater than the first threshold; alternatively, the power reduction unit 22 reduces the charging power when the temperature of a predetermined number of portions of the terminal is greater than the first threshold. The preset number can be set according to the requirement, such as one, two, three, etc., for example: when the temperature of one part of the terminal is greater than the first threshold value and the temperatures of the other parts are not greater than the first threshold value, the power reduction unit 22 does not reduce the charging power; when the temperatures of two or more portions of the terminal are greater than the first threshold, the power reduction unit 22 reduces the charging power.

In some embodiments, the power reduction unit 22 reduces the charging power by: in a power reduction process, when the temperature of the terminal is detected to be greater than a first threshold value for the first time, reducing a charging power set value; the temperature of the terminal is detected regularly by the temperature detection unit 21 with the preset time as a period; when the temperature of the terminal is still larger than the first threshold value, the set value of the charging power is continuously reduced; and stopping reducing the charging power when the temperature of the terminal is less than or equal to the first threshold. Therefore, the temperature of the terminal can be just lower than the first threshold value by reducing the charging power gradually, and the situation that the charging power is reduced too much at one time is prevented so as to keep a faster charging speed.

In other embodiments, the power reduction unit 22 reduces the charging power by: in a power reduction process, when the temperature of the terminal is detected to be greater than a first threshold value for the first time, reducing a charging power set value; the temperature of the terminal is detected regularly by the temperature detection unit 21 with the preset time as a period; when the temperature of the terminal is still larger than the first threshold value and the charging power is larger than the lower limit value, the set value of the charging power is continuously reduced; and when the temperature of the terminal is less than or equal to the first threshold value or the charging power is less than or equal to the lower limit value, stopping reducing the charging power. Therefore, the charging speed is prevented from being influenced by too low charging power by setting the lower limit value of the charging power.

The foregoing power reduction process is the whole process from the first time of reducing the charging power to the time of stopping reducing the charging power.

Alternatively, in one power reduction flow, when the charging power is reduced at least twice, the value of each reduction of the charging power by the power reduction unit 22 is equal. For example, the charging power is reduced three times in one power reduction process, and the value of each reduction of the charging power is 2W.

Alternatively, in one power reduction process, when the power reduction unit 22 reduces the charging power at least twice, the values of the at least two adjacent times of reducing the charging power are not equal. For example, in a power reduction process, the charging power is reduced three times, the value of the charging power is reduced for the first time and the second time, the value of the charging power is reduced for the second time and the third time, for example, the charging power is reduced for the first time by 2W, and the charging power is reduced for each of the second time and the third time by 1W.

Further, the processing module 20 further includes a power increasing unit 23, where the power increasing unit 23 is configured to: and when the temperature is less than a second threshold value, the charging power is increased, wherein the first threshold value is greater than the second threshold value.

The second threshold value is used as a lower limit value of the temperature to prevent the charging speed from being influenced by the fact that the charging power is too low, and the temperature of the terminal is kept between the first threshold value and the second threshold value, so that the user experience is not influenced by the fact that the temperature of the terminal is too high, the charging speed is not reduced by the fact that the charging power is too low, and the charging speed and the user experience are both considered.

When the temperatures of at least two parts of the terminal are detected, the power increasing unit 23 increases the charging power as long as the temperature of any one part is less than the second threshold; alternatively, the power increasing unit 23 increases the charging power when the temperature of the predetermined number of portions of the terminal is less than the second threshold. The preset number can be set according to the requirement, such as one, two, three, etc., for example: when the temperature of one part of the terminal is less than a second threshold value and the temperatures of other parts of the terminal are not less than the second threshold value, the charging power is not increased; and when the temperature of two or more parts of the terminal is less than the second threshold value, the charging power is increased. Specifically, the power increasing unit 23 may increase the charging power by increasing the charging current or the charging voltage.

In some embodiments, the power increasing unit 23 increases the charging power by: in a power increasing process, when the temperature of the terminal is detected to be smaller than a second threshold value for the first time, increasing a set value of charging power; the temperature of the terminal is detected regularly by the temperature detection unit 21 with the preset time as a period; when the temperature of the terminal is still smaller than the second threshold value, the set value of the charging power is continuously increased; and when the temperature of the terminal is greater than or equal to the second threshold value, stopping increasing the charging power. Through improving the power of charging one by one for the temperature at terminal can be steady fall into suitable scope, prevents that the temperature from greatly falling, has kept the stability of charging.

In other embodiments, the power increasing unit 23 increases the charging power by: in a power increasing process, when the temperature of the terminal is detected to be smaller than a second threshold value for the first time, increasing a set value of charging power; the temperature of the terminal is detected regularly by the temperature detection unit 21 with the preset time as a period; when the temperature of the terminal is still smaller than the second threshold value and the charging power is smaller than the upper limit value, continuously increasing the set value of the charging power of the terminal; and when the temperature of the terminal is greater than or equal to the second threshold value or the charging power is greater than or equal to the upper limit value, stopping increasing the charging power. By setting the upper limit value of the charging power, the charger is prevented from being influenced by overhigh charging power.

The foregoing power increase procedure is the whole process from the first time of increasing the charging power to the time of stopping increasing the charging power.

Alternatively, in one power boosting procedure, when the charging power is boosted at least twice, the value of the charging power per boosting by the power boosting unit 23 is equal. For example, in one power increasing process, the charging power is increased three times, and each time the charging power is increased, the value is 2W.

Alternatively, in one power increasing procedure, when the power increasing unit 23 increases the charging power at least twice, the values of the increasing charging power at least two adjacent times are not equal. For example, in one power increasing process, the charging power is increased three times, the value of the charging power increased for the first time is different from that increased for the second time, and the value of the charging power increased for the second time is the same as that increased for the third time, for example, the charging power is increased for the first time by 2W, and the charging power is increased for each of the second time and the third time by 1W.

Optionally, when the processing module 20 executes the second charging strategy, the charging power may be directly increased to a second predetermined level, and the charging is performed at full speed, so as to ensure the charging speed; the temperature of the terminal may also be sensed and the charging power may be gradually increased to a second predetermined level as the temperature of the terminal decreases to prevent a sudden temperature increase caused by an instantaneous increase in the charging power.

According to the charging device provided by the embodiment of the invention, the use state of the target application program with larger calorific value is monitored in the charging process, when the target application program is detected to be in the running state, the first charging strategy with lower charging power is immediately executed, so that the user experience is prevented from being influenced by serious heating of the terminal, and when the target application program is detected to be in the non-running state, the second charging strategy with higher charging power is executed, so that the charging speed is ensured. Therefore, the use experience of a user is improved in the quick charging process, the charging speed and the use experience of the user are both considered, the satisfaction degree of the user is improved, and the competitiveness of a product is improved.
