Example one
Referring to fig. 1, a charging method of a smart device according to a first embodiment of the present invention is proposed, the method including the steps of:
and S11, charging by adopting a first charging strategy.
In the embodiment of the present invention, the first 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 is also added with a second charging strategy, wherein the charging power of the first charging strategy is larger than that of the second charging strategy.
and S12, judging whether the system time of the intelligent device is in the preset charging time. If the charging time is determined to be the predetermined charging time, the process goes to step S13; and if the charging time is not within the preset charging time, no operation is executed, and the first charging strategy is continuously adopted for charging.
specifically, after the intelligent device is connected with the charger and starts charging, the intelligent device acquires the system time in real time or in a timed manner, and then compares the acquired time with the preset charging time to judge whether the acquired time falls into the preset charging time. When the charging time falls into the preset charging time, judging that the charging time is currently in the preset charging time; and when the charging time does not fall within the preset charging time, judging that the charging time is not in the preset charging time currently.
the intelligent device can detect the time information of the intelligent device and can also obtain the time information through a network.
The preset charging time can be preset in the intelligent device when the intelligent device leaves a factory, can be set by a user on the intelligent device in a self-defined mode, and can be set automatically by the intelligent device.
Optionally, the smart device provides a setting interface, receives a start-stop time input by a user on the setting interface, and then sets a time period defined by the start-stop time as the predetermined charging time. For example, the intelligent device adds a preset charging time setting option in a setting menu, a user enters a setting interface after clicking the preset charging time setting option, the setting interface displays the starting time and the ending time, the user inputs the starting time of 22:00 and the ending time of 06:00 on the setting interface, and the intelligent device sets the time of 22:00-06:00 as the preset charging time after clicking the setting interface or quitting the setting interface.
Alternatively, the smart device counts usage habit information of the user using the smart device, for example, the usage habit information of the user in a period of one week, half month, one month, and the like may be counted continuously, and then the predetermined charging time may be set according to the usage habit information. The usage habit information generally includes information that the user does not use the smart device for a certain continuous period of the day, and the smart device may extract the continuous period of the day during which the user does not use the smart device from the usage habit information, and set the continuous period as the predetermined charging time. In one embodiment, the intelligent device counts the probability distribution of continuous time periods when the user does not use the intelligent device in one day according to the use habit information, and extracts the continuous time period with the maximum probability value to set the continuous time period as the preset charging time; in another embodiment, the smart device extracts a common continuous period of time during which the user does not use the smart device for a statistical period of time to set as the predetermined charging time.
The intelligent device can continuously or regularly count the use habits of the user and update the preset charging time according to the counting result.
And S13, charging by adopting a second charging strategy.
If the current charging time is preset, the intelligent device enables the sleep charging function, executes a second charging strategy, and properly reduces the charging speed to protect the battery.
Optionally, if the current time is in the predetermined charging time, the smart device directly reduces the charging power to the first predetermined level. For example, the charging power is directly reduced to 60% -90% of the charging power of the first charging strategy, but may be set to other values as needed. In the embodiment of the invention, when the intelligent device reduces the charging power, the reduction of the charging power can be realized by reducing the charging current or the charging voltage.
further, after the charging power is reduced to a first preset level, the intelligent device also detects the electric quantity of the battery; when the electric quantity is within a preset range, reducing the charging power to a second preset level; wherein the first predetermined level is higher than the second predetermined level.
specifically, the range of the electric quantity of the battery can be preset, the intelligent device detects the electric quantity of the battery, and whether the electric quantity of the battery is within the preset range is judged. When the electric quantity of the battery is not in the preset range, keeping the charging power at a first preset level; when the charge amount of the battery is within the preset range, the charging power is further reduced to a second preset level. For example, the first predetermined level may be set to 60% -90% of the charging power of the first charging strategy, and the second predetermined level may be set to 10% -20% of the charging power of the first charging strategy, although other values may be set as needed.
generally, when the battery capacity of the smart device is low (e.g., < 20%) and high (e.g., > 80%), the battery aging is accelerated by charging with a large current, so that the preset range can be set to be less than 20% and/or greater than 80%, that is, when the current battery capacity is less than 20% and/or greater than 80%, the smart device further reduces the charging power; when the current electric quantity of the battery is between 20% and 80%, the intelligent device does not reduce the charging power any more. The range setting of the battery capacity is related to the battery technology, and the specific range can be set according to the recommendation of a battery manufacturer. Further, when a plurality of ranges are set, the charging power levels corresponding to the different ranges may be the same or different.
as shown in fig. 2, a graph is shown of charging current as a function of battery charge of the smart device. Wherein, curve 1 represents the charging process of the traditional quick charging mode, the current of the constant current stage is 1.5C, and the current gradually attenuates when the charging process is close to full charging until the end; curve 2 represents the charging process of the charging method of the smart device according to the embodiment of the present invention at the predetermined charging time, which reduces the maximum charging current to within 0.5C; the charging current is further controlled at low charge (< 20%) or high charge (> 80%), e.g. down to within 0.2C, and gradually decays towards full charge until completion.
Optionally, if the current time is within the predetermined charging time, the smart device first determines whether a preset condition is met, and reduces the charging power when the preset condition is met. The conditions may be set by battery level, smart device temperature, etc.
In one embodiment, a temperature threshold is preset, the temperature of the motherboard, the battery, the screen, the central processing unit, the graphics processing unit, the power management unit and other parts of the smart device is detected, preferably, the temperature of the battery is detected, and the detected temperature is compared with the threshold. When the temperature is less than or equal to the threshold value, the first charging strategy is kept, and the current charging power is not changed; the charging power is only reduced when the temperature is greater than the threshold.
generally, when the battery is charged at a battery temperature within a range of 10 to 40 ℃, the deterioration of the battery is small, and therefore, the threshold value may be set to 40 ℃. Of course, the range corresponding to different batteries may be different, so the threshold value may be set according to the recommendation of the battery manufacturer.
when the temperature is greater than the threshold, the charging power may be reduced to a predetermined level (which may be the same as or different from the aforementioned first predetermined level or second predetermined level) at one time, such as to 80%, 90%, etc. of the charging power of the first charging strategy, and the specific percentage may be set as required; the charging power setting value may also be gradually decreased until the temperature is less than or equal to the threshold value, so as to prevent the charging speed from being excessively decreased by decreasing the charging power too much at one time, for example, each time the charging power is decreased by 2W, then the temperature is detected again after a preset time interval, and when the temperature is still greater than the threshold value, the charging power is decreased again by 2W until the temperature is less than or equal to the threshold value.
In another embodiment, the range of the electric quantity of the battery is preset, and the intelligent device detects the electric quantity of the battery and judges whether the electric quantity of the battery is within the preset range. When the electric quantity of the battery is not in the preset range, keeping the first charging strategy and not changing the current charging power; when the charge level of the battery is within a predetermined range, the charging power is reduced to a predetermined level (which may be the same as or different from the first predetermined level or the second predetermined level). For example, the predetermined level may be set to 60% -90% of the charging power of the first charging strategy, may also be set to 10% -20% of the charging power of the first charging strategy, and may of course be set to other values as needed. Further, when a plurality of ranges are set, the charging power levels corresponding to the different ranges may be the same or different.
further, after the second charging strategy is executed, the current charging strategy is displayed on a User Interface (UI), such as a prompt to the user that the charging has been optimized, the charging speed has been reduced, the battery is in a protected state, and the like.
Furthermore, after the second charging strategy is executed, when the current charging time is detected to be no longer in the preset charging time, the charging by adopting the first charging strategy is resumed, and the charging power is increased to the first charging strategy level.
according to the charging method of the intelligent device, the sleep charging function is added to the intelligent device, when the charging time is preset, the second charging strategy is executed in consideration of the fact that the user does not need the charging speed at the moment, the charging speed is reduced, the aging of the battery is slowed down, the safety of the battery is improved, the requirement of the user on the charging speed and the protection of the battery are considered, the charging flexibility is improved, and the user experience is improved.
Example two
Referring to fig. 3, a charging method of a smart device according to a second embodiment of the present invention is proposed, the method including the steps of:
and S21, charging by adopting a first charging strategy.
and S22, judging whether the sleep charging mode is started or not. When the sleep charging mode is turned on, step S23 is performed; and when the sleep charging mode is not started, no operation is executed, and the first charging strategy is continuously adopted for charging.
in this embodiment, a sleep charging mode is added, and a user can turn on or off the sleep charging mode to realize the switch of the sleep charging function. When the sleep charging mode is started, the sleep charging function of the intelligent equipment is started, and the intelligent equipment enters the sleep charging mode within preset charging time; when the sleep charging mode is closed, the sleep charging function of the intelligent device is closed, and the intelligent device adopts a first charging strategy for charging. The user can start the sleep charging mode before charging starts, and can also start the sleep charging mode in real time in the charging process.
optionally, the intelligent device adds a sleep charging mode option in the setting menu, the user can check or cancel the sleep charging mode to realize the start or the stop of the sleep charging mode, and the intelligent device updates the setting information according to the operation of the user. After charging is started or when updating of the setting information is detected in the charging process, the setting information is read, and whether the sleep charging mode is started or not is judged according to the setting information.
Optionally, when the smart device receives a preset operation instruction, the sleep charging mode is turned on or off. Such as an operation of pressing a specific key, an operation of touching a screen, a volley gesture action, a voice command, and the like.
And S23, judging whether the system time of the intelligent device is in the preset charging time. If the charging time is determined to be the predetermined charging time, the process goes to step S23; and if the charging time is not within the preset charging time, no operation is executed, and the first charging strategy is continuously adopted for charging.
This step S23 is the same as step S12 in the first embodiment, and is not repeated here.
And S24, charging by adopting a second charging strategy.
And if the current charging time is preset, entering a sleep charging mode, executing a second charging strategy, and properly reducing the charging speed to protect the battery. This step S24 is the same as step S13 in the first embodiment, and is not repeated here.
further, after executing the second charging strategy, the current charging strategy is displayed on the user interface, for example, the user is prompted to enter a sleep charging mode, the charging is optimized, the charging speed is reduced, the battery is in a protection state, and the like.
Further, after the second charging strategy is executed, when it is detected that the current charging time is no longer within the preset charging time, the charging by using the first charging strategy is resumed, and the charging power is increased to the first charging strategy level.
Further, when the sleep charging mode is turned off, the charging with the first charging strategy is resumed, and the charging power is raised to the first charging strategy level.
In specific implementation, the User Interface (UI), the system layer and the driver layer of the smart device can be improved, wherein:
a user interface: the system is used for providing a sleep charging mode switch and a preset charging time setting, and a user can select whether a sleep charging function is enabled or not through the sleep charging mode switch on a user interface and configure the preset charging time (such as 22:00-06: 00). Generally, the user of the predetermined charging time has low requirements on the charging speed, so that the charging current can be reduced.
A system layer: the interface is used for providing an operation interface between the user interface and the driving layer, and can complete data transmission of control commands, parameters, states and the like; monitoring system time, sending a charging state switching command to the driving layer when entering/exiting the preset charging time, and informing a user interface to change the currently displayed mode (mainly informing the user of the current charging mode to avoid misunderstanding of the user.)
A driving layer: the system layer is used for receiving control instructions and control parameters transmitted by the system layer, determining the current charging strategy, driving the power supply management module to enter different charging modes, and returning the current working state to the system layer.
the specific process is as follows:
1) If the sleep charging mode is started, judging whether the current time is in the preset charging time or not after the charging is started; if the charging time is preset, entering a sleep charging mode, executing a second charging strategy, and if the charging current is determined to be the most reasonable currently according to the current electric quantity, the temperature and other factors, reducing the charging power according to the determination; if not, maintaining the first charging strategy;
2) if the sleep charging mode is not started, maintaining the first charging strategy;
3) if the sleep charging function is closed in the charging process, the sleep charging mode is exited, and the charging is resumed by adopting the first charging strategy;
4) And if the sleep charging function is enabled in the charging process, executing the step 1).
according to the charging method of the intelligent equipment, the sleep charging mode is added for the user to start or close, so that the user can start or close the sleep charging function at any time according to actual needs, the humanization degree of the intelligent equipment is improved, and the user experience is further improved.

in one embodiment, the determining module 10 obtains the system time in real time or at regular time after the smart device is connected to the charger to start charging. The determining module 10 may detect time information of the local device, or may obtain the time information through a network.
in another embodiment, after the charging is started or during the charging process, the determining module 10 first determines whether the sleep charging mode is turned on; when the sleep charging mode 10 is started, acquiring time information and judging whether the system time of the intelligent device is in a preset charging time; when the sleep charging mode is not turned on, no operation is performed.
Optionally, the intelligent device adds a sleep charging mode option in the setting menu, the user can check or cancel the sleep charging mode to realize the start or the stop of the sleep charging mode, and the intelligent device updates the setting information according to the operation of the user. After the charging is started or when the update of the setting information is detected in the charging process, the judging module 10 reads the setting information and judges whether the sleep charging mode is started or not according to the setting information.
optionally, when a preset operation instruction is received, the determining module 10 turns on or off the sleep charging mode. Such as an operation of pressing a specific key, an operation of touching a screen, a volley gesture action, a voice command, and the like.

When the preset charging time is included, judging that the system time is in the preset charging time; when the predetermined charging time does not fall, it is determined that the system time is not at the predetermined charging time.
In this embodiment, the predetermined charging time is preset in the smart device when the smart device leaves a factory.
the processing module 20: the charging system is used for charging by adopting a first charging strategy, and when the charging system is judged to be in a preset charging time, charging is carried out by adopting a second charging strategy; and the charging power of the first charging strategy is greater than that of the second charging strategy.
Specifically, the processing module 20 obtains the determination result, and when the determination result is that the current charging time is in the predetermined charging time, the sleep charging function is enabled, the second charging strategy is executed, and the charging speed is appropriately reduced to protect the battery; and when the judgment result is that the current charging time is not within the preset charging time, no operation is executed, and the first charging strategy is continuously adopted for charging. In the embodiment of the present invention, when the processing module 20 reduces the charging power, the charging power can be reduced by reducing the charging current or the charging voltage.
Alternatively, if the current time is within the predetermined charging time, the processing module 20 directly reduces the charging power to the first predetermined level. For example, the charging power is directly reduced to 80%, 90%, etc. of the charging power of the first charging strategy, and the specific percentage may be set as needed.
Further, after the charging power is reduced to the first predetermined level, the processing module 20 further detects the electric quantity of the battery; when the electric quantity is within a preset range, reducing the charging power to a second preset level; wherein the first predetermined level is higher than the second predetermined level.
Specifically, the range of the battery power may be preset, and the processing module 20 detects the battery power and determines whether the battery power is within the preset range. When the electric quantity of the battery is not in the preset range, keeping the charging power at a first preset level; when the charge amount of the battery is within the preset range, the charging power is further reduced to a second preset level. For example, the first predetermined level may be set to 60% -90% of the charging power of the first charging strategy, and the second predetermined level may be set to 10% -20% of the charging power of the first charging strategy, although other values may be set as needed.
Generally, when the battery capacity of the smart device is low (e.g., < 20%) and high (e.g., > 80%), the battery aging is accelerated by charging with a large current, so that the preset range can be set to be less than 20% and/or greater than 80%, that is, when the current battery capacity is less than 20% and/or greater than 80%, the processing module 20 further reduces the charging power; when the current battery capacity is between 20% and 80%, the processing module 20 does not decrease the charging power. The range setting of the battery capacity is related to the battery technology, and the specific range can be set according to the recommendation of a battery manufacturer. Further, when a plurality of ranges are set, the charging power levels corresponding to the different ranges may be the same or different.
As shown in fig. 2, a graph is shown of charging current as a function of battery charge of the smart device. Wherein, curve 1 represents the charging process of the traditional quick charging mode, the current of the constant current stage is 1.5C, and the current gradually attenuates when the charging process is close to full charging until the end; curve 2 represents the charging process of the smart device of the embodiment of the present invention at a predetermined charging time, which reduces the maximum charging current to within 0.5C; the charging current is further controlled at low charge (< 20%) or high charge (> 80%), e.g. down to within 0.2C, and gradually decays towards full charge until completion.
Alternatively, if the current time is within the predetermined charging time, the processing module 20 first determines whether a preset condition is met, and then decreases the charging power when the preset condition is met. The conditions may be set by battery level, smart device temperature, etc.
In one embodiment, a temperature threshold is preset in the smart device, and the processing module 20 detects the temperature of the motherboard, the battery, the screen, the cpu, the graphic processor, the power management unit, and the like of the smart device, preferably detects a problem of the battery, and compares the detected temperature with the threshold. When the temperature is less than or equal to the threshold value, the first charging strategy is kept, and the current charging power is not changed; the charging power is only reduced when the temperature is greater than the threshold.
Generally, when the battery is charged at a battery temperature within a range of 10 to 40 ℃, the deterioration of the battery is small, and therefore, the threshold value may be set to 40 ℃. Of course, the ranges corresponding to different batteries may vary, and therefore, the threshold may be set according to the recommendations of the battery manufacturer.
When the processing module 20 reduces the charging power, the charging power may be reduced to a predetermined level (which may be the same as or different from the aforementioned first predetermined level or second predetermined level) at one time, for example, 80% or 90% of the charging power when the charging power is reduced to the first charging strategy, and the specific percentage may be set as required; the charging power setting value may also be gradually decreased until the temperature is less than or equal to the threshold value, so as to prevent the charging speed from being excessively decreased by decreasing the charging power too much at one time, for example, each time the charging power is decreased by 2W, then the temperature is detected again after a preset time interval, and when the temperature is still greater than the threshold value, the charging power is decreased again by 2W until the temperature is less than or equal to the threshold value.
In another embodiment, the range of the battery power is preset in the smart device, and the processing module 20 detects the battery power and determines whether the battery power is within the preset range; when the electric quantity of the battery is not in the preset range, keeping the first charging strategy and not changing the current charging power; when the charge amount of the battery is within a preset range, the charging power is reduced to a predetermined level (which may be the same as or different from the aforementioned first predetermined level or second predetermined level). For example, the predetermined level may be set to 60% -90% of the charging power of the first charging strategy, may also be set to 10% -20% of the charging power of the first charging strategy, and may of course be set to other values as needed. Further, when a plurality of ranges are set, the charging power levels corresponding to the different ranges may be the same or different.
Further, after executing the second charging strategy, the processing module 20 displays the current charging strategy on a User Interface (UI) through a display screen of the smart device, such as prompting a user that the charging is optimized, the charging speed is reduced, the battery is in a protection state, and the like.
Further, after the second charging strategy is executed, when it is detected that the current charging time is no longer within the predetermined charging time, the processing module 20 resumes the charging with the first charging strategy, and raises the charging power to the first charging strategy level.
according to the intelligent device provided by the embodiment of the invention, by adding the sleep charging function to the intelligent device, when the charging time is preset, and considering that the user does not need the charging speed at the moment, the second charging strategy is executed, the charging speed is reduced, the aging of the battery is slowed down, the safety of the battery is improved, the requirement of the user on the charging speed and the protection of the battery are considered, the charging flexibility is improved, and the user experience is improved.
meanwhile, the sleep charging mode is added for the user to start or close, so that the user can start or close the sleep charging function at any time according to actual needs, the humanization degree of the intelligent device is improved, and the user experience is further improved.
Example four
referring to fig. 5, a smart device according to a fourth embodiment of the present invention is proposed, which is different from the third embodiment in that a setting module 30 is added to the third embodiment, and the setting module 30 is used for setting a predetermined charging time. The predetermined charging time of the present embodiment may be set by a user or automatically set by the smart device.
Alternatively, the setting module 30 provides a setting interface, receives the start and stop time input by the user at the setting interface, and then sets the time period defined by the start and stop time as the predetermined charging time. For example, the setting module 30 adds a preset charging time setting option in the setting menu, the user enters the setting interface after clicking the preset charging time setting option, the setting interface displays the start time and the end time, the user inputs the start time of 22:00 and the end time of 06:00 on the setting interface, and the setting module sets the time of 22:00-06:00 as the preset charging time after clicking the setting interface or quitting the setting interface.
Alternatively, the setting module 30 may count the usage habit information of the user using the smart device, for example, the usage habit information of the user in a period of one week, half month, one month, and the like may be counted continuously, and then the predetermined charging time may be set according to the usage habit information. The usage habit information generally includes information that the user does not use the smart device for a certain continuous period of the day, and the setting module 30 may extract the continuous period of the day during which the user does not use the smart device from the usage habit information, and set the continuous period as the predetermined charging time. In an embodiment, the setting module 30 counts probability distribution of continuous time periods when the user does not use the smart device in one day according to the usage habit information, extracts the continuous time period with the maximum probability value, and sets the continuous time period as the predetermined charging time; in another embodiment, the setup module 30 extracts a common continuous period of time during which the user does not use the smart device for a statistical period of time as the predetermined charging time.
The setting module 30 may continuously or periodically count the usage habits of the user, and update the predetermined charging time according to the statistical result.
Therefore, the preset charging time is set through the setting module 30, so that the preset charging time is set to be more in line with the living habits of the user, and the user experience is further improved.
