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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and 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 application.

A terminal charging control method is applied to a mobile terminal and comprises the following steps: when the battery of the mobile terminal is being charged, determining the current input power and output power of the battery; calculating rated maximum power according to rated capacity and rated maximum voltage of the battery; determining a target control instruction according to the rated maximum power, the input power and the output power; and controlling the charging operation according to the target control instruction.

As shown in fig. 1, fig. 1 is a schematic flowchart of a terminal charging control method provided in an embodiment of the present application, where the terminal charging control method is applied to a mobile terminal, and a specific flow may be as follows:

s101, when a battery of the mobile terminal is charged, determining the current input power and output power of the battery.

For example, the step S101 may specifically include:

acquiring the current charging current, charging voltage, output current and output voltage of the battery;

calculating the product of the charging current and the charging voltage to obtain input power;

and calculating the product of the output current and the output voltage to obtain the output power.

In this embodiment, during the charging process of the battery, the charging current, the charging voltage, the output current and the output voltage are not fixed and may change in real time, the charging current and the charging voltage depend on the stability of the provided power supply, and the output current and the output voltage are determined by the turn-on condition of the terminal application, the aging condition of the hardware device, and the like. Assuming that the input power is P1, the output power is P2, the instantaneous charging current is I1, the instantaneous charging voltage is V1, the instantaneous output current is I2, and the instantaneous output voltage is V2, P1 ═ I1 × V1, and P2 ═ I2 × V2.

And S102, calculating rated maximum power according to the rated capacity and the rated maximum voltage of the battery.

In this embodiment, the rated capacity and the rated maximum voltage are generally specified by the battery manufacturer, and these pieces of information are stored in a designated location in the mobile terminal when the mobile terminal is shipped from the factory. Assuming that the rated capacity is Q and the rated maximum voltage is Vmax, the rated maximum power Pmax is V max Q/h 1/1000, for example, if V max is 4.35V and C is 3000mAh, Pmax is 4.35V (3000mAh)/1000 1/h, where (3000mAh)/1000 represents the conversion of the battery capacity m Ah into Ah, and when 1/h is taken as a unit hour, P max is 13.05 (w).

And S103, determining a target control instruction according to the rated maximum power, the input power and the output power.

For example, referring to fig. 2, the step S103 may specifically include:

s1031, calculating the sum of the input power and the output power to obtain actual power;

s1032, judging whether the rated maximum power is larger than the actual power, if so, executing the following step S1033, otherwise, executing the following step S1034;

s1033, acquiring a first preset instruction as a target control instruction, wherein the first preset instruction is used for indicating that the charging speed is increased;

s1034, a second preset instruction is obtained to serve as a target control instruction, and the second preset instruction is used for indicating the running of the control terminal application.

In this embodiment, the first preset instruction and the second preset instruction are manually set in advance. When Pmax is larger than P, the current charging condition is completely in the maximum bearing range of the battery, the charging speed of the battery can be improved, when Pmax is smaller than or equal to P, the current charging condition is beyond the maximum bearing range of the battery, the battery can be damaged, and at the moment, the output condition of the battery can be controlled.

And S104, controlling the charging operation according to the target control instruction.

For example, when the target control command is a first preset command, please refer to fig. 3, where the step S104 may specifically include:

S1041A, calculating rated maximum current according to the rated maximum power and a preset resistance value of the battery;

S1042A, determining a target current according to the rated maximum current;

and S1043A, increasing the input power of the charging operation according to the target current.

In this embodiment, the predetermined resistance value is usually set by a battery manufacturer. When the charging speed of the battery needs to be increased, the bearable maximum charging current can be calculated, and the battery is charged through the charging current. In the actual operation process, the preset resistance value is set as R0, and the rated maximum current is set as Imax, so that the formula Imax can be used²R0 is Pmax and Imax is calculated, the target current is typically slightly less than Imax. Then, the current charging current of the battery is adjusted to be consistent with the target current so as to achieve the purpose of increasing the input power.

For example, when the target control instruction is a second preset instruction, referring to fig. 4, the step S104 may specifically include:

S1041B, detecting the current background running application and the background staying time of the background running application;

S1042B, determining a target application from the background running application according to the background staying time;

and S1043B, closing the target application to reduce the output power of the charging operation.

In this embodiment, generally, the longer the background staying time of a certain running application is, the more the user is represented to use the application infrequently, and the weaker the importance of the user is, at this time, it may be preferable to close such an application, for example, a running application whose background staying time exceeds a certain time, or a plurality of running applications whose background staying time is longest, as target applications, to close.
