FIG. 1 is a flow chart illustrating a charging method according to an exemplary embodiment; the charging method can be applied to electronic devices (e.g., smart phones, tablet computers), as shown in fig. 1, the charging method includes the following steps 101-103:
in step 101, when a battery of an electronic device is charged with a first charging power, whether a display screen of the electronic device is lighted is detected, and when the display screen is lighted, step 102 is executed, and when the display screen is not lighted, the battery of the electronic device is continuously charged with the first charging power.
In an embodiment, the first charging power may be a charging power when the charger charges a battery of the electronic device in a normal state. In an embodiment, when the display screen of the electronic device is lighted, a lighting event may be generated by a system of the electronic device, and the system of the electronic device notifies the battery management chip of the electronic device of the lighting event, so that the battery management chip may know that the display screen is lighted.
In step 102, when the display screen is illuminated, a duration of the display screen from a point in time of the illuminated display screen is determined.

In step 103, when the duration exceeds a first preset threshold, the charging power of the battery is adjusted from a first charging power to a second charging power, and the second charging power is lower than the first charging power.
In an embodiment, the first preset threshold may be determined according to a charging power of the electronic device during normal charging, for example, the charging power of the electronic device is large, the first preset threshold may be set smaller, the charging power of the electronic device is small, and the first preset threshold may be set larger. In an embodiment, the setting manner of the second charging power may be determined according to the remaining capacity of the battery and the power consumption of the battery during charging.
In this embodiment, when the display screen of the electronic device is lit and the duration of the display screen from the lit time point exceeds the first preset threshold, the charging power of the battery is adjusted from the first charging power to the second charging power, and since the second charging power is lower than the first charging power, the input energy of the electronic device in the screen-lit state can be limited, and the limitation of the heating process of the electronic device by controlling the input energy of the electronic device in the charging process is realized, so that the performance degradation caused by the triggering of a temperature control mechanism by a system of the electronic device is avoided, and it is ensured that a user can normally use the electronic device in the charging state.

obtaining the consumed power of the battery in unit time through the average value of the output current and the average value of the output voltage in unit time;

when the screen-off event occurs in the preset time length of the display screen, the battery is controlled to be charged with the first charging power.
Please refer to the following embodiments for details of how to charge the electronic device.
Therefore, the method provided by the embodiment of the disclosure can limit the input energy of the electronic device in the bright screen state, and limit the heating process of the electronic device by controlling the input energy of the electronic device in the charging state, thereby avoiding performance degradation caused by triggering a temperature control mechanism by a system of the electronic device, and ensuring that a user can normally use the electronic device in the charging state.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
FIG. 2A is a flowchart of a charging method according to an exemplary embodiment and FIG. 2B is a flowchart of step 203 according to an exemplary embodiment; in this embodiment, by using the above method provided by the embodiment of the present disclosure, an example of how to determine the second charging power is described, as shown in fig. 2A, the method includes the following steps:
in step 201, the output current and output voltage of the battery while charging are determined by the battery management chip of the electronic device.
In step 202, the power consumed by the battery while charging is determined from the output current and the output voltage.
In one embodiment, because the electronic device is uncertain when running the application program, the energy consumption of the battery of the electronic device is also uncertain, and the battery management chip can calculate the average value of the output current and the average value of the output voltage of the battery during charging in a unit time (for example, in seconds), obtain the consumed power of the battery during the unit time through the average value of the output current and the average value of the output voltage in the unit time, and further accumulate the consumed power of the battery during the unit time from the time point of charging start (the time point corresponds to one unit time, for example, 1 second) to each time point during charging, obtain the consumed power of the battery during charging, thereby ensuring the accuracy of the consumed power.
In step 203, a second charging power is determined according to the current remaining capacity and the consumed power of the battery.
In an embodiment, the remaining power may be divided according to the interval range, if the remaining power is higher, the second charging power may be set to a lower value, otherwise, if the remaining power is lower, the second charging power may be set to a higher value, for example, the remaining power is 90%, the electronic device is still charged by the charger, since 90% of the power may maintain the electronic device being used by the user for a longer time, for example, the user may use the electronic device for 5 hours, at this time, in order to reduce the heat consumption of the electronic device due to the charging power, the adjustment of the second charging power to a lower value, for example, the adjustment of the second charging power to 30% of the first charging power may be reduced; for another example, the remaining power of the electronic device is 15%, the electronic device is still charged by the charger, since 15% of the power is not enough to maintain the electronic device to be used by the user for a long time, for example, the user may use the electronic device for 30 minutes, at this time, in order to reduce the heat consumption of the electronic device due to the charging power and ensure that the user can use the electronic device normally, the second charging power may be adjusted to a larger value, for example, 80% of the first charging power.
As shown in fig. 2B, for an example of how to determine the second charging power according to the current remaining capacity and the consumed power of the battery, step 203 may include:
in step 211, a range corresponding to the current remaining capacity of the battery is determined.
In one embodiment, the range may be determined according to a test that the electronic device is charging and running the application, for example, the range is divided into [0, 10% ], [ 10%, 20% ], [ 20%, 40% ], [ 40%, 60% ], [ 60%, 80% ], [ 80%, 100% ], and if the current remaining capacity of the battery is 85%, the range corresponding to 85% is [ 80%, 100% ].
In step 212, a second charging power is determined according to the preset coefficient and the consumed power corresponding to the interval range.
In an embodiment, for example, when the range corresponding to the remaining capacity is [ 60%, 80% ] or [ 80%, 100% ], if the preset coefficient corresponding to the range is [ 20%, 40% ] or [ 40%, 60% ], if the range corresponding to the remaining capacity is [ 20%, 40% ] or [ 40%, 60% ], the second charging power may be set to 0.8 times the first charging power, if the preset coefficient corresponding to the range is 0.8, and if the range corresponding to the remaining capacity is [0, 10% ] or [ 10%, 20% ], if the preset coefficient corresponding to the range is 1.2, the second charging power may be set to 1.2 times the first charging power. It will be understood by those skilled in the art that the interval range and the preset coefficient illustrated in the present embodiment are only an exemplary illustration, and should not form a limitation to the present disclosure.
In this embodiment, the second charging power is determined according to the current remaining power and the consumed power of the battery, when the remaining power of the battery is higher, the battery can be charged with lower charging power, and when the remaining power of the battery is lower, the battery can be charged with higher charging power, so that the heat consumption of the electronic device due to the charging power can be reduced, and the user can be ensured to normally use the electronic device; in addition, the second charging power is determined according to the preset coefficient and the consumed power corresponding to the interval range, differential charging can be carried out according to the interval range where the residual electric quantity is located when the battery is charged, and flexibility of controlling the charging power is improved.
FIG. 3 is a flow chart illustrating a charging method according to an exemplary embodiment two; in this embodiment, an example of how to adjust the charging power in the process that the display screen is in the bright screen state is described by using the above method provided in the embodiment of the present disclosure, as shown in fig. 3, the method includes the following steps:

The description of step 301 may refer to the description of the embodiment shown in fig. 1, and will not be described in detail here.
In step 302, when the display screen is turned on, in the process that the display screen is in the on-screen state, it is monitored whether a screen-off event occurs in the preset time duration on the display screen, when the screen-off event occurs in the preset time duration on the display screen, step 303 is executed, and when the screen-off event does not occur in the preset time duration on the display screen, the battery is charged through the method flow of the embodiment shown in fig. 2A, which is not described in detail in this embodiment.
In an embodiment, when the display screen of the electronic device is turned off, a screen turn-off event may be generated by a system of the electronic device, and the system of the electronic device notifies the battery management chip of the electronic device of the screen turn-off event, so that the battery management chip may know that the display screen is turned off.
In step 303, when a screen-off event occurs within a preset time period, the battery is controlled to be charged with a first charging power.
In this embodiment, when the screen-off event occurs within the preset duration, the battery is controlled to be charged with the first charging power, so that it can be ensured that the charger can charge the battery of the electronic device with the maximum charging power after the user does not use the electronic device, and the limitation of the charging power of the battery by distinguishing the screen-on state and the screen-off state of the display screen is realized, which can limit the heating of the electronic device, and can also avoid the performance degradation caused by the fact that a system of the electronic device triggers a temperature control mechanism when the temperature is higher.
