Detailed Description

The embodiment of the application provides a charging control method and device and a mobile terminal.

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Example one

As shown in fig. 1, an execution main body of the method may be a mobile terminal, where the mobile terminal may be a device such as a personal computer, or a mobile terminal device such as a mobile phone and a tablet computer, and the terminal device may be a terminal device used by a user. The method can be applied to the control and other processes of safe charging of the mobile terminal. The method may specifically comprise the steps of:

in step S102, when it is detected that the charging current of the mobile terminal reaches a predetermined current threshold, a current time point is acquired.

The mobile terminal may be a mobile phone, a tablet computer, or the like. The predetermined current threshold may be a preset threshold of the charging current, and the predetermined current threshold may be a charging current capable of making the heat generated by the mobile terminal in a unit time exceed a predetermined heat threshold, and in practical applications, the predetermined current threshold is related to a rated charging current in a fast charging mode of the mobile terminal, and may be specifically set according to practical situations, for example, a rated charging current in a fast charging mode of a commonly used mobile terminal, and specifically, such as 2A (2 amperes), 4.5A, or 5A, and the like.

In implementation, with the continuous development of terminal technology, mobile terminals are more and more popular, the functions of the mobile terminals are more and more increased, and the display screens are also larger and larger, so that the power consumption of the mobile terminals is larger and larger, and therefore, the battery capacity adopted by the mobile terminals is gradually increased by mobile terminal manufacturers. Due to the increase of battery capacity, many mobile terminal manufacturers adopt a fast charging technology of the battery, which fast charges the battery of the mobile terminal by increasing a charging current, without increasing a charging time or increasing a charging speed, wherein a specific charging voltage and current may be 9V/2A, 5V/4.5A, etc.

In order to improve the charging speed and improve the user experience, the charging current adopted by the rapid charging technology is increasingly large, the heating phenomenon generated by the mobile terminal during charging is more and more obvious due to the increase of the charging current, the generated heat is also increasingly large, and especially when the user charges and uses the mobile terminal, the heating caused by rapid charging is very serious, and the user experience is influenced. The battery of the mobile terminal can be fully charged in about 2 hours through quick charging, the electric quantity of a mobile phone is sufficient when many users go out for the next day, the mobile terminal is connected with the charger for charging in the sleeping process at night, and the mobile terminal can be continuously charged overnight under most conditions. If the mobile terminal is placed in a quilt or under a pillow, heat generated in the process of rapid charging is not easy to dissipate from the quilt or under the pillow, so that potential safety hazards may be brought to users, and for this reason, the embodiment of the present application provides a control method for safe charging, which can specifically refer to the following contents:

in order to eliminate potential safety hazards brought to users by charging of the mobile terminal as much as possible, the mobile terminal may preset a limiting current (i.e., a predetermined current threshold) of the mobile terminal during charging in one or more time periods, where one or more time periods may be set by the user or set according to actual conditions, such as a night time period, specifically, the night time period is set to be 23:00 to 6: 00. As shown in fig. 2, a charging port is usually provided in the mobile terminal, and in order to distinguish whether to charge the mobile terminal or perform data interaction with the mobile terminal, after a user connects a data line, the charging port usually detects the purpose of connecting the data line this time (i.e. charging the mobile terminal or performing data interaction with the mobile terminal), if the data line is connected this time for performing data interaction with the mobile terminal, the mobile terminal may be set to a data interaction mode, and if the data line is connected this time for charging the mobile terminal, the mobile terminal may further detect whether to perform normal charging or fast charging, wherein different chargers may have different charging modes, or a plurality of different charging modes may be provided on one charger, different charging modes can be embodied in the magnitude of the charging current, for example, the charging current for normal charging can be 0.5A to 1.5A, etc., and the charging current for fast charging can be 2A or more than 2A, etc. In the night, in order to ensure the charging safety of the mobile terminal, if it is detected that the mobile terminal is charged by a conventional charging method, the mobile terminal may be continuously charged by this method without performing subsequent processing, and if it is detected that the charging current of the mobile terminal is large and exceeds a predetermined current threshold (for example, charging by a fast charging method (the charging current is 2A or more than 2A, etc.), the information related to the current time may be acquired. And controlling the charging current of the mobile terminal through the related information of the current time and the set night time period.

In step S104, if the current time point is within a predetermined time period, the use state of the mobile terminal is acquired.

The preset time period can be set by a user according to actual conditions, or can be preset by a developer of the mobile terminal, and the preset time period can be one or multiple, for example, the preset time period is 23: 00-6: 00, or the preset time period includes 23: 00-6: 00, 12: 00-14: 00 and the like. The usage state of the mobile terminal may be used to characterize whether the mobile terminal is currently in a used state. The use state of the mobile terminal may be embodied in various ways, for example, when the display screen of the mobile terminal is in the continuous lighting state for a period of time longer than a predetermined period of time (e.g., 5 minutes or 10 minutes), it may be determined that the mobile terminal is being used by the user, or when the mobile terminal is in the screen locking state, it may be determined that the mobile terminal is not being used by the user, etc.

In implementation, after the mobile terminal obtains the current time point, the current time point may be compared with a preset time period (i.e., a preset time period), if the current time point is not within the preset time period, it indicates that the current time point has no charging limitation on the mobile terminal, at this time, the mobile terminal may charge the mobile terminal using a preset current threshold or a charging current exceeding the preset current threshold, if the current time point is within the preset time period, it indicates that the current time point has a limitation on the charging current of the mobile terminal, at this time, considering that if the current user is using the mobile terminal, a potential safety hazard existing in the charging process of the mobile terminal may be discovered by the user at any time, so as to make a corresponding adjustment policy, in this case, the charging safety problem of the mobile terminal may not need to be considered, based on this, when the mobile terminal determines that the current time point is within the preset time period, the use state of the mobile terminal can be acquired.

In step S106, if the usage state of the mobile terminal is the unused state, the charging current of the mobile terminal is reduced, and the mobile terminal continues to be charged.

In an implementation, if the usage state of the mobile terminal is determined to be the unused state in the above manner, in order to ensure the charging safety of the mobile terminal, and avoid the mobile terminal from generating a large amount of heat when charging with a high charging current, the charging current of the mobile terminal may be reduced to be below the predetermined current threshold, or a charging current with relatively less heat generated during charging, such as 1A or 0.5A, may be preset, and the mobile terminal may be continuously charged with the adjusted charging current.

It should be noted that, in order to ensure the charging safety of the mobile terminal, after the charging current is adjusted in the above manner, the temperature of the mobile terminal may be continuously monitored, and when the temperature of the mobile terminal exceeds a preset temperature threshold, the charging current of the mobile terminal may be continuously reduced, and the mobile terminal may be continuously charged. Therefore, the temperature of the mobile terminal is monitored, the charging current of the mobile terminal is adjusted timely, and the charging safety of the mobile terminal is guaranteed.

The embodiment of the application provides a charging control method, which includes acquiring a current time point when a charging current of a mobile terminal is detected to reach a predetermined current threshold, wherein the predetermined current threshold is related to a rated charging current of the mobile terminal in a fast charging mode, acquiring a use state of the mobile terminal if the current time point is in a predetermined time period, reducing the charging current of the mobile terminal and continuing to charge the mobile terminal if the use state of the mobile terminal is in an unused state, so that the mobile terminal actively reduces the charging current of the mobile terminal when the mobile terminal detects that the mobile terminal is currently charged in the fast charging mode, the current time point is in the predetermined time period, and the use state of the mobile terminal is in the unused state, so that the mobile terminal is kept in a safe charging state and avoids more heat generated by the mobile terminal, thereby guaranteeing the safety of the user and the mobile terminal in charging.

Example two

As shown in fig. 3, an execution main body of the method may be a mobile terminal, where the mobile terminal may be a device such as a personal computer, or a mobile terminal device such as a mobile phone and a tablet computer, and the terminal device may be a terminal device used by a user. The method can be applied to the control and other processes of safe charging of the mobile terminal. The method may specifically comprise the steps of:

in step S302, when it is detected that the charging current of the mobile terminal reaches a predetermined current threshold, the current time point is obtained, wherein the predetermined current threshold is related to a rated charging current of the mobile terminal in a fast charging mode.

The predetermined current threshold may be a rated charging current corresponding to a fast charging condition, such as 2A, 5A, and the like.

The content of the step S302 is the same as the content of the step S102 in the first embodiment, and the specific processing procedure of the step S302 may refer to the related content in the step S102, which is not described herein again.

In step S304, if the current time point is within a predetermined time period, the use state of the mobile terminal is acquired.

The content of the step S304 is the same as the content of the step S104 in the first embodiment, and the specific processing procedure of the step S304 may refer to the related content in the step S104, which is not described herein again.

In step S306, if the usage status of the mobile terminal is an unused status, the remaining power of the mobile terminal is acquired.

The unused state may include a screen lock state or a power-off state.

In implementation, when the usage state of the mobile terminal is determined to be the unused state, if the remaining power of the mobile terminal is large, it may be considered that the standby state of the mobile terminal is not affected, or it may be dealt with the user using the mobile terminal at any time thereafter, if the remaining power of the mobile terminal is small, at this time, if the user needs to use the mobile terminal, the power consumption speed of the mobile terminal in the process of using the mobile terminal is faster than that of the standby state, if the charging current is small at this time, the mobile terminal will be slowly charged, and the user experience is poor, for this reason, if the mobile terminal detects that the mobile terminal is currently in the screen locking state or the power off state, it may be determined that the current usage state is the unused state, at this time, the mobile terminal may detect the remaining power of the battery, and thereby obtaining the remaining power of the mobile terminal, wherein the representation manner of the remaining power may, such as 20% or 10% of the total charge of the mobile terminal battery.

In addition, in order to ensure that the user does not use the mobile terminal in a short time, the processing of detecting the remaining power and reducing the charging current may be performed after a certain period of time when the usage state of the mobile terminal is changed to the non-usage state, and specifically may include the following: and if the using state of the mobile terminal is the unused state and the duration of the unused state exceeds a first preset duration threshold, reducing the charging current of the mobile terminal and continuously charging the mobile terminal.

The first predetermined time threshold may be set according to actual conditions, specifically, 15 minutes or 20 minutes, for example. The unused state can be represented by a dormant state, a screen locking state or a power-off state of the mobile terminal. The process of reducing the charging current of the mobile terminal and continuing to charge the mobile terminal may refer to the related content of step S308 described below or the related content of step S106 in the first embodiment.

In step S308, if the remaining power is greater than the set power threshold, the charging current of the mobile terminal is decreased, and the mobile terminal is continuously charged.

The electric quantity threshold value can be set according to actual conditions, and specifically can be 20% or 10% of the total electric quantity of the mobile terminal battery. The electric quantity threshold value can be adjusted by a user according to actual conditions, and can also be preset by a mobile terminal manufacturer.

In implementation, if the remaining power of the mobile terminal is obtained in the above manner, the remaining power may be compared with the set power threshold, and if the obtained remaining power is less than the set power threshold, no processing may be performed, that is, the mobile terminal may continue to use the charging current that reaches or exceeds the predetermined current threshold to charge the mobile terminal until the remaining power of the mobile terminal reaches the set power threshold. If the remaining power of the mobile terminal is greater than the set power threshold, it indicates that the current remaining power of the mobile terminal is relatively sufficient, and at this time, in order to ensure the charging safety of the mobile terminal, avoid the mobile terminal from generating a large amount of heat when charging with a higher charging current, the charging current of the mobile terminal may be reduced to below the predetermined current threshold, or a charging current with relatively less heat generated in the charging process, such as 1A or 0.5A, may be preset, and the mobile terminal is continuously charged through the adjusted charging current.

The process of reducing the charging current of the mobile terminal and continuing to charge the mobile terminal in step S308 may include various implementation manners, and the following provides an optional processing manner, which may specifically include the following steps: and adjusting the charging current of the mobile terminal to a set first charging current, and continuously charging the mobile terminal through the first charging current, wherein the first charging current is smaller than a preset current threshold value.

The first charging current may be smaller than a predetermined current threshold, the first charging current may be adjusted at any time by a user according to an actual situation, and may also be preset by a manufacturer of the mobile terminal, for example, the first charging current is 0.5A or 0.8A.

In an implementation, after the mobile terminal determines that the mobile terminal needs to reduce the charging current one by one through the above conditions, if it is determined that the mobile terminal needs to reduce the charging current, the mobile terminal may adjust the current charging current to a first charging current, for example, the predetermined charging current is 2A, and the first charging current is 0.5A, when it is detected that the charging current of the mobile terminal reaches 2A, it may be determined whether the current time point is within a predetermined time period, if so, it may be determined whether the usage state of the mobile terminal is an unused state, if so, it may be further determined whether the remaining power of the mobile terminal is greater than a set power threshold, and if so, it may reduce the charging current of the mobile terminal from 2A to 0.5A (at this time, it may be referred to as a night safe charging mode, etc.), and continue to charge the mobile terminal through the charging current of 0.5A. If any one of the above judgment conditions is not satisfied, the mobile terminal may be continuously charged with a charging current of 2A or more than 2A.

In addition, in order to ensure the safety of the mobile terminal during the charging process to the maximum extent, when the mobile terminal is charged with a large charging current or an adjusted charging current, the temperature of the battery in the mobile terminal may be detected in real time, and the charging current of the mobile terminal may be further adjusted based on the temperature of the battery, which may be specifically referred to in step S310 and step S314 below.

In step S310, the temperature of the battery in the mobile terminal is detected.

In an implementation, after the charging current of the mobile terminal is reduced in the above manner, a temperature sensor in the mobile terminal may be activated, and the temperature of the battery in the mobile terminal may be periodically (for example, periodically for 10 minutes or 5 minutes) detected by the temperature sensor.

In step S312, if the temperature of the battery exceeds a predetermined first temperature threshold, the charging current of the mobile terminal is decreased by a first predetermined current value, and the mobile terminal is continuously charged.

The first temperature threshold may be set according to an actual situation, specifically, for example, 50 degrees celsius or 70 degrees celsius. The first predetermined current value may be set according to actual conditions, such as 0.05A or 0.07A.

In implementation, after the mobile terminal obtains the temperature of the battery in the mobile terminal in the above manner, the obtained temperature may be compared with a predetermined second temperature threshold, if the temperature of the battery exceeds a predetermined first temperature threshold, indicating that the mobile terminal generates more heat, in order to secure the charging of the mobile terminal, the charging current of the present mobile terminal may be reduced by a first predetermined current value, for example, the charging current of the present mobile terminal is the first charging current (e.g. 0.5A), the mobile terminal may decrease the charging current by a first predetermined current value on the basis of the first charging current, the first charging current may be, for example, 0.5A, the first predetermined current value may be 0.05A, the mobile terminal may adjust the charging current from 0.5A to 0.45A (i.e., 0.5A-0.05A) and then may continue to charge the mobile terminal with 0.45A as the charging current. Meanwhile, the mobile terminal can also continuously detect the temperature of the battery in the mobile terminal, when the detected temperature exceeds the preset first temperature threshold value again, the charging current of the mobile terminal is reduced by the first preset current value again, namely the charging current of the mobile terminal is changed to 0.4A, and the like, so that the safety of the mobile terminal in the charging process is ensured.

In addition, in order to enhance the user experience, a second temperature threshold may be further set in the mobile terminal, and the charging current of the mobile terminal may be further controlled by the second temperature threshold, which may be specifically referred to in step S314 and step S316 below.

In step S314, if the temperature of the battery is lower than a predetermined second temperature threshold, the charging current of the mobile terminal is increased by a second predetermined current value, and the mobile terminal continues to be charged until the charging current of the mobile terminal reaches the first charging current.

The second temperature threshold may be a temperature at which the heat generated by the mobile terminal during the charging process is small, specifically, 10 degrees celsius or 15 degrees celsius, and the first temperature threshold is greater than or equal to the second temperature threshold. The second predetermined current value may be set according to actual conditions, specifically, 0.05A or 0.07A, and the second predetermined current value may be the same as the first predetermined current value or may be different from the first predetermined current value.

In implementation, if the temperature of the battery is detected to be lower than the predetermined second temperature threshold in the above-mentioned processing of step S308 or S312, the charging current of the mobile terminal is increased by a second predetermined current value, and the mobile terminal is continuously charged, for example, the current charging current is 0.5A, the second predetermined current value may be 0.05A, and when the temperature of the battery is detected to be lower than the predetermined second temperature threshold, the charging current may be adjusted from 0.5A to 0.55A. Meanwhile, the mobile terminal can also continuously detect the temperature of the battery in the mobile terminal, when the detected temperature is still lower than the preset first temperature threshold value, the charging current of the mobile terminal is increased by a second preset current value again, namely the charging current of the mobile terminal is changed to 0.6A, and the like, so that the mobile terminal is charged as quickly as possible within the range allowed by the temperature of the battery.

If the temperature of the battery is detected to be lower than the second temperature threshold, the charging current of the mobile terminal is increased by a second predetermined current value, and the mobile terminal is continuously charged until the charging current of the mobile terminal reaches the first charging current, for example, the first charging current is 0.5A, the current charging current is 0.3A, the second predetermined current value may be 0.05A, and when the temperature of the battery is detected to be lower than the second temperature threshold, the charging current may be adjusted from 0.3A to 0.35A. Meanwhile, the mobile terminal can also continue to detect the temperature of the battery in the mobile terminal, when the detected temperature is still lower than the predetermined first temperature threshold value after a predetermined period, the charging current of the mobile terminal is increased again by a second predetermined current value, that is, the charging current of the mobile terminal is changed to 0.4A, and so on until the charging current is adjusted to 0.5A, so that the charging safety of the mobile terminal is ensured.

It should be noted that, if the temperature of the battery exceeds the first temperature threshold after the charging current is increased by the second predetermined current value, the process of step S312 may be executed, otherwise, the process of step S314 is continuously executed.

When the mobile terminal is charged through the above-mentioned process, if the usage status of the mobile terminal changes, that is, the usage status of the mobile terminal changes from the unused status to the used status, it can be determined whether the user needs to use the mobile terminal for a short time or for a long time, and then the charging current of the mobile terminal is controlled, which may be specifically referred to the following steps S316 and S318.

In step S316, when it is detected that the usage state of the mobile terminal is changed from the unused state to the used state, a timer is started.

In implementation, for example, when the mobile terminal is charged by a low charging current, if it is detected that a display screen of the mobile terminal is lit or an application program in the mobile terminal is running, it may be determined that the mobile terminal is currently in a used state, at which time the mobile terminal may take the current time point as a starting time point of the used state and start timing, wherein the mobile terminal may also record the starting time point of the used state.

In step S318, when the duration of the used state reaches the second predetermined duration threshold, the charging current of the mobile terminal is increased, and the mobile terminal is continuously charged.

The second predetermined time threshold may be set according to actual conditions, specifically, 5 minutes or 8 minutes, for example.

In an implementation, when the usage state of the mobile terminal is converted from the non-usage state to the usage state, and the duration of the usage state reaches a second predetermined time threshold (for example, the display screen of the mobile terminal is lit for 5 minutes, etc.), it may be determined that the user uses the mobile terminal, and at this time, the charging safety of the mobile terminal may be perceived by the user, so the mobile terminal may increase the charging current and continue to charge the mobile terminal, for example, the mobile terminal resumes charging the mobile terminal with the predetermined current threshold or the charging current exceeding the predetermined current threshold, or starts a fast charging mode to charge the mobile terminal, etc. When the duration of the used state from the starting time point of the above-mentioned starting timing does not reach the second predetermined time threshold (for example, the user picks up the mobile terminal to check the time or sends a short message, etc.), the mobile terminal may continue to be charged with a lower charging current.

It should be noted that the processing procedures of step S316 and step S318 may be executed after step S312 or step S314, or may be executed after step S308, which is not limited in this embodiment of the application.
