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 embodiment of the invention provides a mobile terminal power supply control method and device, terminal equipment and a storage medium. The device can be integrated in a mobile terminal, and the mobile terminal can be a mobile phone, a tablet computer, a notebook computer, an intelligent watch and other equipment.
For example, as shown in fig. 1, a mobile terminal presets a preset battery capacity for determining whether the current capacity of a battery is sufficient to supply power to a peripheral device, when the peripheral device to be charged, such as a tablet computer, is connected to the mobile terminal through a USB interface, the current capacity of the battery is obtained, the current capacity of the battery is compared with the preset battery capacity, if the current capacity of the battery is greater than the preset battery capacity, it is indicated that the current capacity of the battery is large, a first power supply current is set, a function of supplying power to the peripheral device through the battery is started, and the peripheral device connected to the USB interface is supplied with power through the first power supply current until the current capacity of the battery is not greater than the preset battery capacity. If the current electric quantity of the battery is less than the preset battery electric quantity, the current electric quantity of the battery is less, the charging function needs to be started to supplement the electric quantity for the battery of the mobile terminal while the external device supplies power, a second power supply current is set, the function of supplying power to the external device and the charging function are started by the battery, the second power supply current is used for supplying power to the external device connected with the USB interface, the second power supply current is smaller than the first power supply current until the current electric quantity of the battery is larger than the preset battery electric quantity, so that the smaller power supply current is set to supply power to the external device while the battery supplies power, and the charging time of the mobile terminal is prolonged.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
The embodiment will be described in terms of a mobile terminal controlling a power supply device, which may be specifically integrated in a terminal device, where the terminal device may include a notebook computer, a tablet computer, a smart phone, a smart watch, and the like.
As shown in fig. 2, a specific flow of a method for controlling power supply by a mobile terminal is as follows:
step 201, obtaining the current electric quantity of the mobile terminal battery, and comparing the current electric quantity of the battery with the preset electric quantity of the battery.
For example, after the USB interface of the mobile terminal is connected to the external device, the mobile terminal obtains the current electric quantity of the battery of the mobile terminal, and compares the current electric quantity of the battery with the preset electric quantity of the battery, thereby determining whether the current electric quantity of the battery is enough to supply power to the external device connected to the USB interface.
The preset battery electric quantity is a basis for judging whether the current electric quantity of the battery is enough to supply power to the peripheral equipment or not, the preset battery electric quantity is not limited, and can be flexibly set according to actual conditions, for example, the preset battery electric quantity can be 20%, namely the preset battery electric quantity can be 20% of the total electric quantity of the battery of the mobile terminal.
In some embodiments, after the peripheral device is connected to the mobile terminal through the USB interface, the mobile terminal may default to use the USB interface to consume its own battery power to charge the peripheral device, the user may enter a setting function interface of the mobile terminal, and manually set the mobile terminal to stop using the USB interface to consume its own battery power to charge the peripheral device, or set the mobile terminal to use the USB interface to provide other functions, such as functions of sharing a network and/or sharing files, for the peripheral device.
For example, the mobile terminal compares the current electric quantity of the battery with the preset electric quantity of the battery, if the comparison result shows that the current electric quantity of the battery is larger than the preset electric quantity of the battery, the current electric quantity of the battery of the mobile terminal is larger, the current electric quantity is enough to supply power to a peripheral connected with the mobile terminal through a USB interface, a larger current is set as a first power supply current at the moment, the function of supplying power to the peripheral through the battery is started, and the first power supply current is used for supplying power to the peripheral until the current electric quantity of the battery is not larger than the preset electric quantity of the battery.
The setting of the magnitude of the first supply current is not limited, and can be flexibly set according to actual conditions, for example, 1000 mA.
The peripheral equipment is external equipment connected with the mobile terminal, and can be mobile phones, and/or intelligent watches, and/or intelligent door locks and other equipment.
In some embodiments, if the current electric quantity of the battery is greater than the preset battery electric quantity, the mobile terminal periodically obtains the current electric quantity of the battery, compares the current electric quantity of the battery with the preset battery electric quantity, determines the current electric quantity of the battery and the preset battery electric quantity, continues to use the first power supply current to supply power to an external device connected with the mobile terminal through the USB interface if the current electric quantity of the battery is greater than the preset battery electric quantity, and executes step 203 if the current electric quantity of the battery is not greater than the preset battery electric quantity.
The interval time for the mobile terminal to acquire the current electric quantity of the battery each time is not limited, and can be flexibly set according to actual conditions, and the interval time for the mobile terminal to acquire the current electric quantity of the battery each time can be the same, for example, the interval time for each time is 60 seconds.
In one embodiment, the interval between the two times of acquiring the current power of the battery by the mobile terminal may be different from each other, that is, the mobile terminal may acquire the current power of the battery at any time. The interval time for acquiring the current electric quantity of the battery every two times can be regularly changed, for example, the interval time for acquiring the current electric quantity of the battery every two times by the mobile terminal can be in the form of an arithmetic progression, that is, the mobile terminal acquires the current electric quantity of the battery regularly according to the change rule of the interval time.
In one embodiment, if the current electric quantity of the mobile terminal battery is greater than the preset battery electric quantity, it indicates that the current electric quantity of the mobile terminal battery is large enough to supply power to the peripheral connected with the mobile terminal through the USB interface, and the mobile terminal may turn off the charging function, stop charging the battery, and only start the battery to supply power to the peripheral with the first supply current.
In one embodiment, the current electric quantity of the mobile terminal battery is greater than the preset battery electric quantity, although the current electric quantity of the mobile terminal battery is more and enough to supply power to the peripheral connected with the mobile terminal by using the USB interface, in order to avoid the situation that the electric quantity required by the peripheral connected with the mobile terminal is larger, the mobile terminal charges the peripheral by using a larger current in a short time, so that the battery electric quantity of the mobile terminal is sharply reduced, and the situations that the mobile terminal is shut down or the battery is damaged are caused, the mobile terminal can start a charging function, and the battery is charged under the situation that the peripheral is supplied with power by using the first supply current.
For example, the mobile terminal compares the current electric quantity of the battery with the preset electric quantity of the battery, if the comparison result shows that the current electric quantity of the battery is not larger than the preset electric quantity of the battery, the current electric quantity of the battery of the mobile terminal is less and is not enough for supplying power to an external device connected with the mobile terminal by using the USB interface, at the moment, the battery is stopped to supply power to the external device by using the first supply current, a smaller current is set as a second supply current, the function of supplying power to the external device by using the battery and the charging function are started, the external device is supplied with power by using the second supply current, and the battery is charged at the.
The setting of the magnitude of the second supply current is not limited, and can be flexibly set according to actual conditions, for example, 200 mA.
In some embodiments, the power of the battery for supplying power to the peripheral at the second power supply current is less than the power of the battery for supplying power to the peripheral at the first power supply current, and the second power supply current is set to be less than the first power supply current in order to prolong the time for which the battery of the mobile terminal supplies power to the peripheral.
In some embodiments, the mobile terminal sets the state identification value and the time identification value when the battery is charged and the battery is started to supply power to the peripheral at the second supply current.
The state identification value is used for identifying the state of the mobile terminal when the mobile terminal supplies power for the peripheral, the setting of the state identification value is not limited, and the state identification value can be flexibly set according to actual conditions, for example, the state identification value can be 1.
The time identification value is used for identifying the specific time when the mobile terminal supplies power to the external device by the second power supply current.
In one embodiment, when the current electric quantity of the mobile terminal battery is not greater than the battery electric quantity, it indicates that the current electric quantity of the mobile terminal battery is less, so that after the mobile terminal sets the second power supply current, the mobile terminal sets the charging current to charge the battery, and starts the battery to supply power to the external device with the second power supply current.
In some embodiments, when the current electric quantity of the mobile terminal battery is not greater than the electric quantity of the battery, it indicates that the current electric quantity of the mobile terminal battery is less, so that after the mobile terminal sets the second supply current, the mobile terminal sets the charging current to charge the battery, and starts the battery to supply power to the peripheral device with the second supply current.
In one embodiment, the mobile terminal supplies power to the peripheral device at a second supply current, and while charging the battery with the charging current, if the charging current is less than the supply current, or the mobile terminal supplies power to the peripheral equipment at a certain moment by using a larger current, so that the electric quantity of the battery of the mobile terminal is sharply reduced, thereby causing the mobile terminal to be in a closed state, stopping charging the peripheral equipment by the second power supply current, charging the battery only by the charging current, when the battery power reaches a certain level, the mobile terminal is changed from the off state to the on state, the current state value is detected, the current state value is compared with the state identification value, if the current state value is equal to the state identification value, the mobile terminal is indicated to be in a state of supplying power for the peripheral equipment at present, at the moment, the battery is stopped to supply power to the peripheral equipment by using the second power supply current, a third power supply current is set, and the battery is started to supply power to the peripheral equipment by using the third power supply current.
In some embodiments, when the third supply current is set, the current time may be obtained, a difference between the current time and the time identification value may be calculated, the difference may be compared with a preset time difference, and the third supply current may be set according to the comparison result.
The preset time difference value comprises two parts, the first part is the time spent on reducing the battery power to zero when the mobile terminal starts to supply power to the peripheral with the second power supply current, and the second part is the time spent on increasing the battery power of the mobile terminal from zero to detecting the battery power of the current state value, so the preset time difference value can be set according to the time sum of the two parts.
Similarly, the difference between the current time and the time stamp value also includes the time taken for the same two-part power change process described above. The difference value between the current time and the time identification value is less than or equal to the preset time difference value.
In one embodiment, if the difference between the current time and the time identification value is smaller than the preset time difference, indicating that the battery has not emptied in the last power supply, the first current difference obtained by subtracting the preset current value from the second power supply current is set as the third power supply current. The supply current is reduced, thereby allowing the battery to drain.
The preset current value is not limited, and can be flexibly set according to actual conditions, for example, 20 mA.
In one embodiment, if the difference between the current time and the time identification value is equal to the preset time difference, indicating that the battery is empty when the battery is supplied last time, a second current difference obtained by subtracting the charging current from the second supply current is set as the third supply current.
The power supply control method of the mobile terminal according to the above embodiments will be described in further detail below.
Referring to fig. 3, fig. 3 is another schematic flow chart of a power supply control method of a mobile terminal according to an embodiment of the present application. The mobile terminal power supply control method may be applied to a mobile terminal, as shown in fig. 3, the flow of the mobile terminal power supply control method may be as follows:
For example, the mobile terminal confirms that the peripheral device is connected by using a USB interface or the like, and the user does not manually turn off the mobile terminal to supply power to the peripheral device, and the mobile terminal supplies power to the peripheral device by default.
Step 302, obtaining the current electric quantity of the battery of the mobile terminal, and comparing the current electric quantity of the battery with the preset electric quantity of the battery.
For example, the mobile terminal presets a preset battery power for judging whether the current power of the battery is enough to supply power to the peripheral, and obtains the current power of the battery to compare with the preset battery power.
For example, if the comparison result indicates that the current electric quantity of the battery is greater than the preset battery electric quantity, it indicates that the current electric quantity of the battery of the mobile terminal is large enough to supply power to the peripheral connected with the mobile terminal by using the USB interface, and at this time, a large current is set as a first supply current to supply power to the peripheral by using the first supply current.
And step 304, judging whether the current electric quantity of the battery is larger than the preset battery electric quantity.
For example, if yes, the process returns to step 303, and the mobile terminal continues to supply power to the peripheral device with the first power supply current. If not, go to step 305.
And 305, stopping supplying power to the peripheral equipment by the battery at the first power supply current, and after setting the second power supply current, charging the battery and starting the battery to supply power to the peripheral equipment at the second power supply current.
For example, if yes, the process returns to step 303, and if no, step 307 is executed.
And 307, judging whether the mobile terminal is in a closed state.
For example, if yes, the power supply to the peripheral device with the second power supply current is stopped, and the battery is charged with the charging current until the mobile terminal changes from the off state to the on state, and step 308 is executed. If not, the process returns to step 305.
And 308, when the mobile terminal is changed from the closed state to the open state, detecting the current state value, and comparing the current state value with the state identification value.
For example, the state identification value is set when the battery is charged and started to supply power to the peripheral at the second supply current.
And 309, if the current state value is equal to the state identification value, stopping supplying power to the peripheral equipment by the battery with a second power supply current.
For example, the time identification value is set when the battery is charged and started to supply power to the peripheral at the second supply current.
And 311, if the difference is smaller than the preset time difference, setting a first current difference obtained by subtracting the preset current value from the second power supply current as a third power supply current, and supplying power to the external equipment by using the third power supply current.
And step 312, if the difference is equal to the preset time difference, setting a second current difference obtained by subtracting the charging current from the second supply current as a third supply current, and supplying power to the external equipment by using the third supply current.
The mobile terminal power supply control method provided by the embodiment of the invention is used for determining the preset battery electric quantity as a judgment basis for judging whether the current electric quantity of the mobile terminal battery is enough to supply power to the peripheral equipment, if the current electric quantity of the battery is larger than the preset battery electric quantity, the current electric quantity of the mobile terminal battery is more, a larger first power supply current is set, and the battery can be started to supply power to the peripheral equipment by using the first power supply current under the condition that the charging function is not started to store power for the battery, until the current electric quantity of the battery is not larger than the preset battery electric quantity. If the current electric quantity of the battery is not larger than the preset battery electric quantity, the current electric quantity of the battery of the mobile terminal is less, the current electric quantity is insufficient to supply power for the peripheral equipment, the charging function needs to be started to store the electric power for the mobile terminal, the battery is stopped to supply power to the peripheral equipment by using the first supply current, and a smaller second supply current is set until the current electric quantity of the battery is larger than the preset battery electric quantity. The embodiment of the invention can prolong the power supply time of the external equipment under the condition that the battery of the mobile terminal has less electric quantity, avoid the condition that the mobile terminal utilizes large current for power supply in a short time to damage energy storage components such as a battery and the like, and prolong the service life of the energy storage components of the mobile terminal.
