The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
The present embodiment will be described from the perspective of a mobile terminal control power supply device, which may be specifically integrated in a terminal device, and 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 of a mobile terminal is as follows:
step 201, obtaining the current electric quantity of a battery of the mobile terminal, 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 its battery, and compares the current electric quantity of the battery with the preset electric quantity of the battery, so as to determine whether the current electric quantity of the battery is sufficient to supply power to the peripheral device of the USB interface.
The preset battery power is a preset basis of the mobile terminal for judging whether the current power of the battery is enough to supply power to the peripheral, the setting of the preset battery power is not limited, and the preset battery power can be flexibly set according to practical situations, for example, the preset battery power can be 20%, that is, the preset battery power can be 20% of the total power of the battery of the mobile terminal.
In some embodiments, after the peripheral is connected to the mobile terminal by using the USB interface, the mobile terminal may default to consume its battery power to charge the peripheral by using the USB interface, and the user may enter a function setting interface of the mobile terminal to manually set the mobile terminal to stop consuming its battery power to charge the peripheral by using the USB interface, or may set the mobile terminal to provide other functions for the peripheral by using the USB interface, for example, functions of sharing a network and/or sharing a file.
Step 202, if the current electric quantity of the battery is larger than the preset battery electric quantity, setting a first power supply current, and starting the battery to supply power to the outside by the first power supply current until the current electric quantity of the battery is not larger than the preset battery electric quantity.
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 more, and the mobile terminal is enough to supply power for the peripheral connected with the mobile terminal by using the USB interface, at the moment, a larger current is set as a first power supply current, the function of externally supplying power for the battery is started, and the first power supply current is used for supplying power for the peripheral until the current electric quantity of the battery is not larger than the preset electric quantity of the battery.
The first supply current is not limited in its magnitude, and may be flexibly set according to practical situations, for example, 1000mA.
The peripheral equipment is external equipment connected with the mobile terminal, and can be a mobile phone, an intelligent watch, an intelligent door lock 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, if the current electric quantity of the battery is greater than the preset battery electric quantity, continues to use the first power supply current to supply power for the peripheral connected with the mobile terminal by using the USB interface, and if the current electric quantity of the battery is not greater than the preset battery electric quantity, step 203 is executed.
The interval time of the mobile terminal for obtaining the current electric quantity of the battery at each time is not limited, can be flexibly set according to practical situations, and can be the same, for example, 60 seconds at each time.
In one embodiment, the interval time between each two times of obtaining the current electric quantity of the battery by the mobile terminal may be different from each other, that is, the mobile terminal may obtain the current electric quantity of the battery at any time. The interval time for obtaining the current electric quantity of the battery every two times can be changed regularly, for example, the interval time for obtaining the current electric quantity of the battery every two times of the mobile terminal can be in the form of an arithmetic progression, that is, the mobile terminal regularly obtains the current electric quantity of the battery according to the change rule of the interval time.
In one embodiment, if the current electric quantity of the battery of the mobile terminal is greater than the preset battery electric quantity, the current electric quantity of the battery of the mobile terminal is indicated to be more, and the battery is sufficient to supply power for the peripheral equipment connected with the mobile terminal by using the USB interface, the mobile terminal can close the charging function, stop charging the battery, and only start the battery to supply power to the peripheral equipment with the first power supply current.
In one embodiment, the current electric quantity of the battery of the mobile terminal is larger than the preset battery electric quantity, although the current electric quantity of the battery of the mobile terminal is more, the battery is enough to supply power for 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 uses larger current to charge the peripheral in a short time, so that the battery electric quantity of the mobile terminal is suddenly reduced, the mobile terminal is powered off or the battery is damaged, and the like, and the mobile terminal can start a charging function to charge the battery under the situation that the peripheral is powered by using the first power supply current.
And 203, if the current electric quantity of the battery is not greater than the preset battery electric quantity, stopping the battery to supply power to the external device by the first power supply current, charging the battery and starting the battery to supply power to the external device by the second power supply current after the second power supply current is set, until the current electric quantity of the battery is greater than the preset battery electric quantity.
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 smaller and insufficient to supply power to the peripheral connected with the mobile terminal by using the USB interface, at the moment, the battery stops supplying power to the peripheral by using the first power supply current, a smaller current is set as the second power supply current, the function of supplying power to the peripheral by using the smaller current and the charging function of the battery are started, and the second power supply current is used for supplying power to the peripheral and simultaneously charging the battery.
The second supply current is not limited in its magnitude, and may be flexibly set according to practical situations, for example, 200mA.
In some embodiments, the power of the battery supplying power to the peripheral device with the second power supply current is smaller than the power of the battery supplying power to the peripheral device with the first power supply current, and in order to prolong the time for which the mobile terminal battery supplies power to the peripheral device, the second power supply current is set to be smaller than the first power supply current.
In some embodiments, the mobile terminal sets the status identification value and the time identification value while charging the battery and starting the battery to power the peripheral at the second power supply current.
The state identification value is used for identifying the state of the mobile terminal when the mobile terminal supplies power to the peripheral, the setting of the state identification value is not limited, and the state identification value can be flexibly set according to practical situations, 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 through the second power supply current.
In one embodiment, when the current electric quantity of the battery of the mobile terminal is not greater than the electric quantity of the battery, the current electric quantity of the battery of the mobile terminal is indicated to be smaller, so that after the second power supply current is set, the mobile terminal sets the charging current to charge the battery, and starts the battery to supply power to the outside 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, the current electric quantity of the mobile terminal battery is indicated to be less, so that after the second power supply current is set, the mobile terminal sets the charging current to charge the battery, and starts the battery to supply power to the outside with the second power supply current.
In one embodiment, the mobile terminal uses the second power supply current to supply power to the peripheral, although the battery is charged by the charging current, if the charging current is smaller than the power supply current, or the mobile terminal uses a larger current to supply power to the peripheral at a certain moment, the electric quantity of the battery of the mobile terminal is suddenly reduced, so that the mobile terminal is in a closed state, the charging of the peripheral by the second power supply current is stopped, the battery is only charged by the charging current, when the electric quantity of the battery reaches a certain degree, the mobile terminal is changed from the closed state to the open 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 to the peripheral currently, the battery is stopped from supplying power to the peripheral at the second power supply current, a third power supply current is set, and the battery is started to supply power to the peripheral at 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 is calculated, the difference is compared with a preset time difference, and the third supply current is set according to the comparison result.
The preset time difference value comprises two parts, wherein the first part is the time taken by the mobile terminal to reduce the battery power to zero when the mobile terminal starts to supply power to the peripheral equipment by using the second power supply current, and the second part is the time taken by the mobile terminal to increase the battery power from zero to the battery power when the current state value is detected, so that 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 identification value also includes the time spent in the same two-part power change process described above. The difference between the current time and the time identification value is less than or equal to the preset time difference.
In one embodiment, if the difference between the current time and the time identification value is smaller than the preset time difference, the battery is indicated not to be empty when the battery is powered up last time, and 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 setting of the preset current value is not limited, and can be flexibly set according to practical situations, for example, 20mA.
In one embodiment, if the difference between the current time and the time identification value is equal to the preset time difference, it indicates that the battery is empty when the battery is last powered, and the second current difference obtained by subtracting the charging current from the second power supply current is set as the third power supply current.
The mobile terminal power supply control method described in the above embodiments will be described in further detail below.
Referring to fig. 3, fig. 3 is another 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 can be applied to a mobile terminal, as shown in fig. 3, and the flow of the mobile terminal power supply control method can be as follows:
step 301, confirming the connection of the peripheral.
For example, the mobile terminal confirms that the peripheral is connected by using a USB interface or the like, and the user does not manually turn off the function of the mobile terminal for powering the peripheral, and the mobile terminal defaults to power the peripheral.
Step 302, obtaining the current electric quantity of the battery, 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 for the peripheral power supply, and obtains the current power of the battery and compares the current power with the preset battery power.
Step 303, determining that the current electric quantity of the battery is larger than the preset electric quantity of the battery, setting a first power supply current, and starting the battery to supply power to the outside with the first power supply current.
For example, if the comparison result shows that the current electric quantity of the battery is greater than the preset battery electric quantity, the current electric quantity of the battery of the mobile terminal is more, and the battery is enough to supply power for the peripheral connected with the mobile terminal by using the USB interface, and at the moment, a larger current is set as the first power supply current, and the first power supply current is used for supplying power for the peripheral.
Step 304, judging whether the current electric quantity of the battery is larger than the preset electric quantity of the battery.
For example, if yes, the step 303 is executed back, and the mobile terminal continues to supply power to the external device with the first supply current. If not, go to step 305.
Step 305, stopping the battery to supply power to the external device 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 external device at the second power supply current.
Step 306, judging whether the current electric quantity of the battery is larger than the preset electric quantity of the battery.
For example, if yes, go back to step 303, if no, go to step 307.
Step 307, determining whether the mobile terminal is in a closed state.
For example, if so, 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 is changed from the off state to the on state, and step 308 is performed. If not, go back to execute step 305.
Step 308, when the mobile terminal changes from the off state to the on state, detecting the current state value, and comparing the current state value with the state identification value.
For example, the status identification value is set when the battery is charged and started to supply power to the peripheral device at the second supply current.
Step 309, if the current status value is equal to the status identifier value, stopping the battery to supply power to the peripheral device with the second power supply current.
Step 310, obtaining the current time, and calculating the difference between the current time and the time identification value.
For example, the time identification value is set when charging the battery and starting the battery to supply power to the external device at the second supply current.
Step 311, if the difference is smaller than the preset time difference, the first current difference obtained by subtracting the preset current value from the second power supply current is set as a third power supply current, and the peripheral is powered by the third power supply current.
Step 312, if the difference is equal to the preset time difference, the second current difference obtained by subtracting the charging current from the second supply current is set as a third supply current, and the peripheral is supplied with power by the third supply current.
According to the mobile terminal power supply control method provided by the embodiment of the invention, the preset battery power is determined and used as the judging basis for judging whether the current power of the battery of the mobile terminal is enough for peripheral power supply, if the current power of the battery is larger than the preset battery power, the current power of the battery of the mobile terminal is larger, the larger first power supply current is set, and the battery can be started to supply power by taking the first power supply current as the peripheral power under the condition that the charging function is not started to store power for the mobile terminal, until the current power of the battery is not larger than the preset battery power. If the current electric quantity of the battery is not more than the preset battery electric quantity, the current electric quantity of the battery of the mobile terminal is less and insufficient to supply power to the peripheral equipment, a charging function is required to be started to store power for the peripheral equipment, the battery is stopped to supply power to the outside through a first power supply current, and a smaller second power supply current is set until the current electric quantity of the battery is more than the preset battery electric quantity.
