Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The first embodiment is as follows:
an embodiment of the present invention provides a charging method, which is applied to control charging of a battery disposed in an electronic device, and specifically, as shown in fig. 1, is a flowchart of steps of the method in the embodiment of the present invention, where the method may include the following steps:
step 101: and acquiring the light intensity of the environment where the electronic equipment is located.
Optionally, the electronic device may be an electronic terminal such as a smart phone, a tablet computer, an electronic reader, a smart watch, and a smart band, which is not limited herein.
Also optionally, the implementation subject of the charging method may be a setting function module of an application processor of the electronic device, that is, the charging method may be implemented by the application processor of the electronic device; the main body of the charging method may also be a specially configured controller, such as an MCU (Micro Control Unit), and this embodiment is not limited herein.
Preferably, the acquiring the light intensity of the environment where the electronic device is located may specifically include:
and acquiring the light intensity of the environment where the electronic equipment is located based on the photosensitive element configured by the electronic equipment.
The light sensor may be a light sensor, i.e., a photoelectric sensor, disposed in the electronic device, and the light sensor may convert the collected light signal into an electrical signal, so that a relevant processing module, such as an application processor or an MCU, obtains the light intensity of the environment where the electronic device is located according to the electrical signal.
Step 102: if the acquired light intensity is determined to be lower than or equal to a set light intensity threshold, stopping charging the battery when the electric quantity stored in the battery of the electronic equipment is determined to be higher than or equal to a preset electric quantity threshold; wherein the preset electric quantity threshold value is lower than the actual capacity value of the battery.
That is, when it is determined that the acquired light intensity is lower than or equal to the set light intensity threshold, it is determined that the current time at which the battery of the electronic device is being charged is night, and the charging of the battery of the electronic device is stopped before the amount of electricity stored in the battery reaches the actual capacity value of the battery, that is, the battery is fully charged.
It should be noted that step 102 may further include: if it is determined that the acquired light intensity is lower than or equal to the set light intensity threshold, if it is determined that the electric quantity stored in the battery of the electronic device is lower than the preset electric quantity threshold, the battery is continuously charged, which is not described herein again.
It should be noted that the intensity of light is proportional to the luminous flux in the environment where the electronic device is located; the set light intensity threshold may be flexibly set according to actual use conditions, and this embodiment is not limited herein.
It should be noted that the actual capacity value of the battery is an amount of electricity that can be actually discharged after the battery is fully charged under a certain discharge condition, and the actual capacity value of the battery decreases as the cycle life of the battery decreases, so that it is difficult to directly specify the actual capacity value of the battery for any battery being charged and to control the end of the charging process when the amount of electricity stored in the battery is lower than the actual capacity value. However, the battery charging process of the prior art electronic device generally includes a trickle phase, a constant current phase, and a constant voltage phase; in the trickle phase, the battery voltage is relatively low, and the battery is pre-charged by adopting small charging current; in the constant current stage, the charging current is basically kept unchanged, and the voltage of the battery is increased along with the progress of the charging process; when the voltage of the battery reaches a certain voltage threshold (for example, 4.4V), the voltage of the battery is basically kept unchanged, the charging current is reduced, and when the charging current is reduced to a charging cutoff current value (which can be preset), the battery is considered to store the electric quantity reaching the actual capacity value, namely, the battery reaches a full charge state, and the charging process is controlled to be ended.
Therefore, the determining that the amount of power stored in the battery is greater than or equal to the preset power threshold may specifically include:
determining that the voltage of the battery is higher than or equal to a first set voltage threshold, wherein the first set voltage threshold is lower than or equal to a rated voltage value of the battery.
The first set voltage threshold value is lower than or equal to the rated voltage value of the battery, and the first set voltage threshold value may be preset to be equal to the rated voltage value of the battery, for example, 4.4V; when the voltage of the battery is determined to be higher than or equal to 4.4V, namely the stored electric quantity of the battery is determined to be higher than or equal to a preset electric quantity threshold value, the battery is stopped to be charged; because the voltage threshold value of the battery charging process converted from the constant current stage to the constant voltage stage is usually close to the rated voltage value of the battery, under the condition, the constant voltage stage can not be carried out in the battery charging process, namely the battery charging process just enters or does not enter the constant voltage stage, the charging process is stopped, and the full charge of the battery can be avoided.
Optionally, the determining that the amount of power stored in the battery is greater than or equal to a preset power threshold may further include:
determining that the charging current of the battery is lower than or equal to a preset current threshold value, wherein the preset current threshold value is higher than a charging cutoff current value of the battery.
In the constant voltage stage of the battery charging process, the voltage of the battery is basically kept unchanged at the rated voltage, for example, 4.4V, and the charging current is reduced; setting the preset current threshold value to be equal to the sum of a charging cut-off current value and a smaller current value (which can be flexibly set according to actual use conditions), and when the charging current is reduced to the preset current threshold value, namely the battery is determined to store the electric quantity higher than or equal to the preset electric quantity threshold value, stopping charging the battery; in this case, the constant voltage phase of the battery charging process is not completed, and the charging process is stopped, thereby preventing the battery from being fully charged.
Further optionally, in order to make the determination on the stored electric quantity of the battery more accurate, and further make it possible to avoid full charge of the battery and ensure that a sufficient amount of electric quantity is stored in the battery, the determining that the stored electric quantity of the battery is higher than or equal to the preset electric quantity threshold may specifically include: determining that the voltage of the battery is higher than or equal to the first set voltage threshold, and determining that the charging current of the battery is lower than or equal to the preset current threshold.
It should be noted that the voltage value and the charging current value of the battery may be obtained based on a fuel gauge in a battery module configured in the electronic device, for example, the application processor may communicate with the battery module to obtain the voltage value and the charging current value of the battery collected by the fuel gauge; a special sampling circuit may be further provided to obtain the battery voltage value and the charging current value, and this embodiment is not limited in any way.
Optionally, before obtaining the light intensity of the environment where the electronic device is located in step 101, the method may further include:
determining that a voltage of the battery is greater than or equal to a second set voltage threshold; wherein the second set voltage threshold is lower than or equal to the first set voltage threshold.
That is, in the process of charging the battery, after determining that the amount of power stored in the battery is close to the actual capacity value of the battery, it can be determined whether the current time at which the battery of the electronic device is being charged is night.
Optionally, the method may further comprise: and if the acquired light intensity is determined to be higher than the set light intensity threshold, continuing to charge the battery until the stored electric quantity of the battery is higher than or equal to the actual capacity value of the battery. That is, when it is determined that the current time when the battery of the electronic device is being charged is daytime, the battery of the electronic device is conventionally charged according to the related art until the amount of electricity stored in the battery is higher than or equal to the actual capacity value of the battery.
Further optionally, after continuing to charge the battery until the amount of electricity stored by the battery is greater than or equal to the actual capacity value of the battery, the method may further comprise:
determining that the time length between the current time and the battery charging end time is higher than or equal to a set time threshold (which can be flexibly set according to actual use requirements, such as 30 minutes);
determining that the amount of power stored by the battery is higher than the preset power threshold;
and acquiring the light intensity of the environment where the electronic equipment is located, and discharging the battery if the acquired light intensity is lower than or equal to the set light intensity threshold.
That is, within a set time after the battery is fully charged, it can be determined again whether the battery is in a fully charged state; if the battery is still in the full charge state, judging whether the current time is at night; if so, discharging the battery to avoid the influence on the service life of the battery due to the fact that the battery of the electronic equipment is in a full charge state for a long time because no user uses the electronic equipment at night after the battery is fully charged.
In addition, the present embodiment does not limit the discharging manner of the battery at all, and for example, the flash of the electronic device may be controlled to be turned on, the display of the electronic device may be controlled to be turned on, and the vibration function of the electronic device may be controlled to be turned on.
The following describes the steps of the charging method provided in this embodiment in detail by taking a specific example as an example:
step A: starting to charge the battery;
and B: determining that the voltage of the battery is not less than a first voltage value (for example, 4.3V), acquiring the light intensity of the environment where the electronic device is located based on the light sensor, and executing step C if it is determined that the acquired light intensity is lower than or equal to a set light intensity threshold; if the acquired light intensity is determined to be higher than the set light intensity threshold, executing a step C';
and C: continuing to charge the battery, stopping charging the battery when the battery voltage is determined to be higher than or equal to the second voltage value (for example, 4.4V) and the charging current is determined to be lower than or equal to the first current value (for example, 0.04c), and jumping to the step G;
step C': continuously charging the battery until the electric quantity stored in the battery reaches the actual capacity value of the battery;
step D': determining that the time length between the current moment and the last charging end moment is not less than a set time threshold (for example, 20 minutes), and acquiring a voltage value of the battery; if the acquired voltage value is determined to be higher than or equal to the second voltage value, executing a step E'; if the acquired voltage value is lower than the second voltage value, jumping to the step G;
step E': acquiring the light intensity of the environment where the electronic equipment is located based on the light sensor, and executing the step F' if the acquired light intensity is determined to be lower than or equal to a set light intensity threshold value; if the acquired light intensity is determined to be higher than the set light intensity threshold value, jumping to the step G;
step F': turning on a flash lamp of the electronic equipment, turning off the flash lamp after keeping turning on for 2 minutes, and skipping to the step G;
step G: and ending the process.
The implementation effect of the charging method provided by this embodiment is shown in the battery cycle graph in fig. 2, where the abscissa is the cycle number, the ordinate is the capacity retention rate, the curve 201 is the cycle curve of the battery left for 8 hours in the non-full-charge state, and the curve 202 is the cycle curve of the battery left for 8 hours in the full-charge state. Assuming that the capacity retention rate rejection threshold of the battery is set to be 90% (when the capacity retention rate of the battery is lower than 90%, the service life of the battery is considered to be exhausted), as can be seen from fig. 2, when the battery is left for 8 hours in a fully charged state, the number of cycles, i.e., the cycle life, of the battery is only about 300 times; and the battery is placed for 8 hours in a non-full-charge state, the cycle number of the battery can be prolonged to about 700 times, and therefore, the service life of the battery of the electronic equipment can be effectively prolonged by the charging method provided by the embodiment.
In summary, the charging method provided in the embodiments of the present invention can be applied to control charging of a battery disposed in an electronic device, and can obtain the light intensity of the environment where the electronic device is located; if the acquired light intensity is determined to be lower than or equal to a set light intensity threshold, stopping charging the battery when the electric quantity stored in the battery is determined to be higher than or equal to a preset electric quantity threshold; wherein the preset electric quantity threshold value is lower than the actual capacity value of the battery. That is, it is possible to determine whether the current time when the battery of the electronic device is being charged is night by obtaining the light intensity of the environment where the electronic device is located; if the battery capacity value is less than the actual capacity value of the battery, the battery is not charged, so that the problem that the cycle life of the battery is shortened because the battery of the electronic equipment is in a full-charge state for a long time after being charged at night is avoided, and the service life of the battery is prolonged.
In addition, for the battery in the full charge state, when the electronic equipment is determined to be not used by people for a long time, the battery can be discharged, and the attenuation of the cycle life of the battery can be further reduced.
In addition, the embodiment of the invention also provides a computer-readable storage medium, and the computer-readable storage medium stores computer-executable instructions, and the computer-executable instructions are used for causing a computer to execute the charging method.
