Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be appreciated that reference throughout this specification to "an embodiment of the present application" or "an embodiment of the foregoing" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrase "in an embodiment of the present application" or "in the foregoing embodiment" appearing in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the various embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application. The above-mentioned serial numbers of the embodiments of the present application are merely for description, and do not represent the advantages and disadvantages of the embodiments.

In the case where no specific description is given, the terminal executes any step in the embodiments of the present application, and the processor of the terminal may execute the step. It should also be noted that the embodiments of the present application do not limit the sequence in which the terminal executes the following steps. In addition, the data may be processed in the same way or in different ways in different embodiments. It should be further noted that any step in the embodiments of the present application may be executed by the terminal independently, that is, when the terminal executes any step in the following embodiments, the terminal may not depend on the execution of other steps.

In the related art, in order to solve the problems that the space occupied by the power supply module in the single power supply module is large and the position in the terminal is not easy to arrange, a scheme that the terminal is provided with double power supply modules is provided. The power supply module may be a battery. In the scheme of dual power supply module power supply, there are the following power supply modes:

the first method is that a first power supply module is adopted to supply power to all power utilization modules in the terminal, and when the electric quantity of the first power supply module is lower than the lowest electric quantity, a second power supply module is used to supply power to all power utilization modules in the terminal. In the power supply mode, when the first power supply module or the second power supply module supplies power to the power utilization module in the terminal, the output current is large, so that the terminal generates heat seriously.

And secondly, dividing all power utilization modules of the terminal into a first power utilization module and a second power utilization module, supplying power to the first power utilization module by using a first power supply module, supplying power to the second power utilization module by using a second power supply module, and controlling the other power supply module to supply power to the first power utilization module and the second power utilization module when the electric quantity of any power supply module is lower than the lowest value of the power supply modules. In this way, although the first power supply module and the second power supply module can respectively supply power to the first electrical module and the second electrical module, when the power amount of one power supply module is lower than the threshold value, the other power supply module still needs to supply power to the first electrical module and the second electrical module, which still causes a serious problem of heat generation of the other power supply module.

Based on the foregoing, an embodiment of the present application provides a control method applied to a terminal, as shown in fig. 1, the method includes the following steps:

step 101: under the condition that the first power supply module supplies power to the first electric module and the second power supply module supplies power to the second electric module, the first residual capacity of the first power supply module and the second residual capacity of the second power supply module are detected.

Alternatively, the terminal may be any terminal having a first power supply module and a second power supply module, such as a server, a mobile phone, a tablet computer, a notebook computer, a palm computer, a personal digital assistant, a portable media player, a smart speaker, a navigation device, a wearable device, a smart band, a pedometer, a digital TV, or a desktop computer. In the embodiment of the application, the terminal can be a mobile phone.

Optionally, the power usage of the first electrical module may be higher than the power usage of the second electrical module during the first duration. The first time duration may be a time duration from a target time to an acquisition time of acquiring the first remaining energy and/or the second remaining energy, a difference between the acquisition time and the target time may be a unit time duration, a set time duration, or another time duration, and a difference between the acquisition time and the target time may be greater than or equal to a period of acquiring the first remaining energy and/or the second remaining energy.

Alternatively, the first electrical module may be a module that needs to be powered continuously, and the second electrical module may be a module that powers the first electrical module when it is activated. Alternatively, the stability of the required amount of power of the first electrical module may be higher than the stability of the required amount of power of the second electrical module. The first and second power consuming modules may constitute all power consuming modules in the terminal.

In one embodiment, the first electrical module may be a core module in the terminal and the second electrical module may be a non-core module in the terminal. The core module is, for example, at least one of a Graphics Processing Unit (GPU), a Central Processing Unit (CPU), a memory, and a radio frequency module in the terminal, and the non-core module is, for example, at least one of a camera module, a screen module, and an audio module in the terminal. In another embodiment, the first and second power utilization modules may be set by a user, for example, the terminal may receive an operation of classifying the plurality of power utilization modules displayed on the display screen by the user, and determine the first and second power utilization modules based on the operation. It should be understood that the determination manner of the first electrical module and the second electrical module can also be determined by other manners, and the above-listed specific determination manners of the first electrical module and the second electrical module do not constitute specific limitations on the first electrical module or the second electrical module.

In this embodiment, the first remaining capacity may be a percentage of a remaining capacity of the first power supply module in a total capacity of the first power supply module, and the second remaining capacity may be a percentage of a remaining capacity of the second power supply module in a total capacity of the second power supply module. In other embodiments, the first remaining capacity is a current remaining capacity of the first power supply module, the second remaining capacity is a current remaining capacity of the second power supply module, and the unit of the current remaining capacity is mAH. The terminal may periodically or aperiodically acquire a first remaining capacity of the first power supply module and a second remaining capacity of the second power supply module. In addition, the terminal may adjust the period for acquiring the first remaining amount and the second remaining amount based on the load capability of the terminal and the current load.

Step 102: and acquiring a first value obtained by subtracting the first residual capacity from the second residual capacity.

Step 103: if the first value is larger than the first threshold value and the current power utilization priority of the first electric module is higher than the current power utilization priority of the second electric module, the first power supply module is switched to supply power to the second electric module, and the second power supply module is switched to supply power to the first electric module.

Wherein the first threshold is greater than zero.

The performance parameter of the first power supply module may be greater than the performance parameter of the second power supply module. The performance parameter may include at least one of a total capacity, a power supply stability, a charging speed, a discharging speed, and the like. In the embodiment of the present application, the first power supply module is a graphene battery, and the second power supply module is a lithium battery. In other embodiments, the first power supply module and the second power supply module may both be graphene batteries or lithium batteries.

The current power utilization priority may include at least one of a current power consumption rate, a current power stability, and a degree of importance of the current power utilization.

The first threshold is greater than zero, and the size of the first threshold can be determined according to actual conditions. In the embodiment of the present application, the first threshold is 15%. In another embodiment, the first threshold may be any value between 10% and 30% except 15%, for example, the first threshold may be 10%, 20%, 30%, or the like. In yet another embodiment, the first threshold may also be any value of 100mAH to 500mAH, for example the first threshold may be 100mAH, 300mAH or 500mAH. The selection of the first threshold may also be related to the total capacity of the first power supply module and/or the total capacity of the second power supply module. The embodiment of the present application does not limit the selection of the first threshold.

The first threshold may also be dynamically variable, i.e. the terminal may determine the first threshold based on the first remaining amount and/or the second remaining amount. For example, the higher the first remaining capacity and/or the second remaining capacity is, the larger the determined first threshold value is, whereas the lower the first remaining capacity and/or the second remaining capacity is, the smaller the determined first threshold value is.

The control method provided by the embodiment of the application is that when the first power supply module supplies power to the first electric module,

under the condition that the second power supply module supplies power to the second power utilization module, detecting first residual capacity of the first power supply module and second residual capacity of the second power supply module; obtaining a first value obtained by subtracting the first residual capacity from the second residual capacity; if the first value is larger than a first threshold value and the current power utilization priority of the first electric module is higher than the current power utilization priority of the second electric module, the first power supply module is switched to supply power to the second electric module, and the second power supply module is switched to supply power to the first electric module; wherein the first threshold is greater than zero. By adopting the technical scheme of the embodiment of the application, under the condition that the first value obtained by subtracting the first residual electric quantity from the second residual electric quantity is larger than the first threshold value and the current power utilization priority of the first electric module is higher, the second power supply module is switched to supply power to the first electric module with higher power consumption, and the power supply module with higher residual electric quantity is used for supplying power to the first electric module with higher current power utilization priority when the double power supply modules supply power, so that the stability of supplying power to the first electric module is improved.

Based on the foregoing embodiments, an embodiment of the present application provides a control method, as shown in fig. 2, the method includes the following steps:

step 201: under the condition that the first power supply module supplies power to the first power module and the second power supply module supplies power to the second power module, the terminal detects first residual capacity of the first power supply module and second residual capacity of the second power supply module.

In the implementation of the present application, the capacity of the first power supply module may be greater than the capacity of the second power supply module; and/or the power supply stability of the first power supply module may be greater than the power supply stability of the second power supply module; and/or the charging speed for charging the first power supply module in the third time period can be greater than the charging speed for charging the second power supply module. In other embodiments, the capacity of the first power supply module may be less than or equal to the capacity of the second power supply module; and/or the power supply stability of the first power supply module may be less than or equal to the power supply stability of the second power supply module; and/or the charging speed for charging the first power supply module in the third time period may be less than or equal to the charging speed for charging the second power supply module. The power supply stability of the power supply module may be determined based on attribute information of the power supply module, and the attribute information of the power supply module may include at least one of model information, manufacturer information, electrolyte information, usage time information, and battery wear rate information of the power supply module.

Step 202: the terminal obtains a first value obtained by subtracting the first residual capacity from the second residual capacity.

Step 203: if the first value is larger than the first threshold value and the current power utilization priority of the first electric module is higher than the current power utilization priority of the second electric module, the terminal enables the first power supply module to be switched to supply power to the second electric module and enables the second power supply module to be switched to supply power to the first electric module.

It should be understood that if the first value is less than or equal to the first threshold, or if the first value is greater than the first threshold and the current power utilization priority of the first electrical module is lower than or equal to the current power utilization priority of the second electrical module, the terminal will continue to control the first power supply module to supply power to the first electrical module and the second power supply module to supply power to the second electrical module.

Wherein, making the first power supply module switch to supply power to the second power utilization module may include: enabling the second power supply module to output a first current which is reduced along with the time to the second electric module, and enabling the first power supply module to output a second current which is increased along with the time to the second electric module; wherein the first current decreases from a third value to zero and the second current increases from zero to the third value; the first current and the second current have the same rate of change. The voltage output by the first power supply module to the second power utilization module is the same as the voltage output by the second power supply module to the second power utilization module, and the power output to the second power utilization module is constant.

Wherein, switching the first power supply module to supply power to the first electric module may include: enabling the first power supply module to output a third current which is reduced along with the time to the first electric module, and enabling the second power supply module to output a fourth current which is increased along with the time to the first electric module; wherein the third current decreases from a fourth value to zero and the fourth current increases from zero to the fourth value; the third current and the fourth current have the same rate of change. The voltage output by the first power supply module to the first electric module is the same as the voltage output by the second power supply module to the first electric module, and the power output to the first electric module is constant.

Step 204: the terminal detects a third remaining capacity of the first power supply module and a fourth remaining capacity of the second power supply module.

Step 205: and the terminal acquires a second value obtained by subtracting the fourth residual capacity from the third residual capacity.

Step 206: if the second value is larger than the second threshold value and the current power utilization priority of the first power module is higher than the current power utilization priority of the second power module, the terminal enables the first power supply module to be switched to supply power to the first power module and enables the second power supply module to be switched to supply power to the second power module.

The second threshold may be less than or equal to the first threshold and greater than or equal to the inverse of the first threshold. For example, when the first threshold is 15%, the second threshold may be any value between-15% and 15%, for example, the second threshold may be-15%, -5%, 0, 5%, or 15%, and the value of the second threshold is not limited in this embodiment of the application. It should be understood that, in the case that the second threshold value is closer to the first threshold value, the power consumption rate of the first electric module is greater than the power consumption rate of the second electric module, and the second electric module can rapidly drop to the second threshold value based on the power consumption rate, so that the first electric module supplies power to the first electric module again, and the first power supply module which supplies power stably can be controlled to supply power to the more important first electric module to the greatest extent; when the second threshold value is closer to the opposite number of the first threshold value, the time for the second photovoltaic module to fall to the second threshold value is longer, so that the problem of frequent switching of power supply caused by the fact that the time for the second photovoltaic module to fall to the first threshold value is shorter can be avoided.

Wherein, switching the first power supply module to supply power to the first electric module may include: enabling the second power supply module to output a fifth current which is reduced along with the time to the first electric module, and enabling the first power supply module to output a sixth current which is increased along with the time to the first electric module; wherein the fifth current decreases from a fifth value to zero and the sixth current increases from zero to the fifth value; the rate of change of the fifth current and the sixth current is the same.

Wherein, switching the second power supply module to supply power to the second power utilization module may include: enabling the first power supply module to output a seventh current which is reduced along with the time to the second electric module, and enabling the second power supply module to output an eighth current which is increased along with the time to the second electric module; wherein the seventh current decreases from a sixth value to zero and the eighth current increases from zero to a sixth value; the rate of change of the seventh current and the eighth current is the same.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a power supply circuit according to an embodiment of the present disclosure. When the value obtained by subtracting the second residual capacity from the first residual capacity is 12%, determining that the first value obtained by subtracting the first residual capacity from the second residual capacity is smaller than a first threshold value, and switching the first power supply module to supply power to the first electric module and switching the second power supply module to supply power to the second electric module.

Referring to fig. 4, fig. 4 is a schematic structural diagram of another power supply circuit according to an embodiment of the present disclosure. When the value obtained by subtracting the first residual capacity from the second residual capacity is 33%, determining that the first value obtained by subtracting the first residual capacity from the second residual capacity is larger than a first threshold value, switching the first power supply module to supply power to the second electrical module, and switching the second power supply module to supply power to the first electrical module.

It should be understood that fig. 3 and 4 are only schematic examples of the power supply circuit, and in a specific implementation process, a specific power supply condition may be determined according to the current remaining power of the first power supply module and the current remaining power of the second power supply module in practice.

In order to prolong the service life of the battery, a minimum electric quantity threshold value needs to be set for the battery, and when the current electric quantity of the battery is lower than the minimum electric quantity threshold value, a power transmission path is cut off so as to avoid that the battery continues to discharge and the service life of the battery is further reduced. Therefore, in the embodiment of the present application, in order to improve the service life of the power supply module of the terminal, after step 103 or step 206, the terminal may further perform the following step a:

step A: and if the first residual capacity is smaller than or equal to the third threshold and the second residual capacity is larger than the fourth threshold, the terminal controls the second power supply module to supply power to the first power utilization module and the second power utilization module.

The third threshold may be a minimum remaining capacity of the first power supply module, the fourth threshold may be a minimum remaining capacity of the second power supply module, and both the third threshold and the fourth threshold are greater than zero.

The third threshold may be greater than, equal to, or less than the fourth threshold. The user or the terminal may determine the third threshold value based on the attribute information of the first power supply module, and may determine the fourth threshold value based on the attribute information of the second power supply module.

Optionally, after step 103 or step 206, the terminal may perform the following step B:

and B, step B: if the first remaining capacity is greater than a third threshold value and the second remaining capacity is less than or equal to a fourth threshold value, the terminal controls the first power supply module to supply power to the first power module and the second power module.

Optionally, after step 103 or step 206, the terminal may perform the following step C:

and C: if the first remaining capacity is smaller than or equal to a third threshold and the second remaining capacity is smaller than or equal to a fourth threshold, the terminal stops supplying power to the first electrical module and stops supplying power to the second electrical module. Optionally, the terminal may also be automatically powered off.

Optionally, after step 103 or step 206, the terminal may further perform the following steps D1 to D3:

step D1: and if the first residual capacity and the second residual capacity are both smaller than the fifth threshold value, the terminal outputs indication information.

Wherein the fifth threshold is greater than the third threshold, and the fifth threshold is greater than the fourth threshold; the indication information is used for prompting a user to select to use the first power supply module or the second power supply module to supply power to the first power module.

The indication information can be displayed through a display screen of the terminal, or the indication information can be played in a voice playing mode. The embodiment of the present application does not limit the output mode of the indication information.

Step D2: if the first instruction obtained based on the indication information is received within the second time period, or if the instruction obtained based on the indication information is not received within the second time period, the terminal determines to use the first power supply module to supply power to the first power module, and uses the second power supply module to supply power to the second power module.

The first instruction carries information that the first power supply module supplies power to the first electric module.

For example, the second time period may be any value of 5 seconds to 10 seconds, for example, the second time period may be 5 seconds, 8 seconds, or 10 seconds. The embodiment of the application does not limit the specific value of the reserved time length.

And D3: if a second instruction obtained based on the indication information is received within a second time period, the terminal determines to use the second power supply module to supply power to the first power module based on the second instruction, and uses the first power supply module to supply power to the second power module.

In fig. 5, although

steps

301 and 302 are shown to be performed after step 103, the present embodiment does not limit the order between performing

steps

301 and 302 and performing steps of other embodiments, for example, steps 301 and 302 may be performed before step 101, or may be performed before step 201, or may be performed within steps 101 to 103 or steps 201 to 206.

The means for increasing the transmission power may be to increase the transmission current with the transmission voltage unchanged, to increase the transmission voltage with the transmission current unchanged, or to increase both the transmission current and the transmission voltage. The means for reducing the transmitted power may be to reduce the transmitted current with the transmitted voltage unchanged, to reduce the transmitted voltage with the transmitted current unchanged, or to reduce both the transmitted current and voltage.

In the actual operation of the terminal, the terminal may increase the transmission power or decrease the transmission power based on the charging environment of the terminal. For example, in one embodiment, the terminal may obtain the current time, and if the current time is day time, it indicates that the user wants to fully charge the power of the terminal as soon as possible, the power transmission power may be increased, and if the current time is night time, it indicates that the user does not have a requirement for rapidly fully charging the power, and the power transmission power may be decreased. In another embodiment, the terminal may obtain surrounding environment information, may provide power for transmission when it is determined that the user needs to frequently use the terminal based on the surrounding environment information, and may reduce the power for transmission when it is determined that the user does not need to frequently use the terminal based on the surrounding environment information. The terminal may also determine to increase the transmission power or decrease the transmission power in other manners, for example, the terminal may also determine to increase the transmission power or decrease the transmission power according to a loss condition of the power supply module or the power supply device is an adapter or a charger, and the like, which is not limited in this embodiment of the application.

In one embodiment, the charging parameters of the first charging module may be determined based on the current remaining capacity of the first charging module, and the charging parameters of the second charging module may be determined based on the current remaining capacity of the second charging module.

In the embodiment corresponding to fig. 5, the power supply to the first power supply module through the first charging module and the power supply to the second power supply module through the second charging module are performed simultaneously, that is, the terminal can control the power supply to the two power supply modules simultaneously. However, the embodiment of the application is not limited to this, and the terminal can also control to supply power to a power supply module independently at a moment, so that the terminal can be provided with one charging module, and the size of the terminal can be further reduced. For example, the charging mode of the terminal may be implemented in either of the following two modes.

The first method comprises the following steps: the terminal can control to charge the first power supply module first, and after the first power supply module is fully charged, for example, when the electric quantity of the first power supply module is 100%, the terminal controls to charge the second power supply module until the electric quantity of the second power supply module is also 100%, and the charging is completed.

And the second method comprises the following steps: the terminal can firstly charge the first power supply module if the terminal determines that the residual electric quantity of the first power supply module is smaller than the residual electric quantity of the second power supply module, when the current residual electric quantity of the first power supply module minus the current residual electric quantity of the second power supply module is larger than a first threshold value, the terminal switches to charge the second power supply module, and when the current residual electric quantity of the second power supply module minus the current residual electric quantity of the first power supply module is larger than the first threshold value, the terminal switches to charge the first power supply module until the electric quantities of the first power supply module and the second power supply module reach 100%, and the charging is completed.
