Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
Before introducing the method, apparatus, and storage medium for charge control provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The method and the device are applied to the scene of terminal equipment charging, in the scene, the battery can be charged through two charging modes of a charge pump or a PMIC, and the charging modes can be switched according to the change of the voltage or the current of the battery. For example, when the voltage reaches a preset voltage threshold, the charging mode is switched. When the battery is charged through the charge pump, the battery can be charged with larger power, and the PMIC is generally not used for high-power charging because the PMIC has lower efficiency and serious heat generation, and cannot keep the charging speed when being used for high-power charging, thereby influencing the charging efficiency; however, when the battery is charged through the PMIC, the PMIC can monitor the change of the battery consumption current, so that the charging current input to the battery is adjusted according to the consumption current, that is, the PMIC can detect the current fed into the battery and feed back the current to the demand side, thereby ensuring the stability of the charging current fed into the battery. The charge pump does not have the feedback capacity, and when the battery is charged through the charge pump, if the battery needs to output current at the moment, the current input into the battery through the charge pump is partially consumed, so that the charging efficiency of the battery by the charge pump is reduced, the battery cannot be charged at a high current, and the stability of the current of the battery cannot be ensured.
In order to solve the above problems, the present disclosure provides a method, an apparatus, and a storage medium for charge control, in which a second preset charging mode is added to charge a battery in a process of charging the battery by using a first preset charging mode, and current compensation is performed in the charging process, so that a problem of low charging efficiency or heat generation in the charging process caused by charging only by using the first preset charging mode is solved, and it is ensured that the charging efficiency of the battery is not affected.
The present disclosure is described below with reference to specific examples.
Fig. 1 is a flowchart illustrating a method for controlling charging according to an exemplary embodiment, and referring to fig. 1, the method is used in a terminal device, which may be a mobile terminal such as a smart phone and a tablet computer, and the method includes the following steps:
in step S101, when it is determined that the battery is charged by using the first preset charging method, a charging current corresponding to the first preset charging method is determined.
The first predetermined charging mode may include charging the battery with a charge pump or charging the battery with a PMIC.
In step S102, a compensation current of a second preset charging mode corresponding to the charging current is obtained according to the target system consumption current.
The target system consumption current may include a current system consumption current, or may include an average system consumption current, which is an average value of a total system consumption current in a preset time period. If the first preset charging mode comprises charging the battery by adopting a charge pump, and the second preset charging mode comprises charging the battery by adopting a PMIC, the target system consumption current is the current system consumption current; if the first preset charging mode comprises charging the battery by adopting the PMIC, and the second preset charging mode comprises charging the battery by adopting the charge pump, the target system consumption current is the average system consumption current.
It should be noted that, if the first predetermined charging mode includes charging the battery by using the PMIC, it is considered that the system consumption current fluctuates greatly in the charging mode. Therefore, in order to more accurately obtain the target system consumption current, an average value of the total consumption current in the preset time period may be obtained, and the average system consumption current may be used as the target system consumption current.
In step S103, the battery is charged by the charging current in the first predetermined charging manner, and the battery is charged by the compensation current in the second predetermined charging manner.
Wherein, under the condition that the first preset charging mode comprises charging the battery by adopting a charge pump, the second preset charging mode comprises charging the battery by adopting a PMIC. And under the condition that the first preset charging mode comprises charging the battery by adopting the PMIC, the second preset charging mode comprises charging the battery by adopting a charge pump.
By adopting the method, the second preset charging mode is added to charge the battery in the process of charging the battery by adopting the first preset charging mode, and current compensation is carried out in the charging process, so that the problem of low charging efficiency or heating in the charging process caused by charging only through the first preset charging mode is solved, and the charging efficiency of the battery is not influenced.
In a possible implementation manner, the first preset charging manner includes charging the battery by using a charge pump, and the second preset charging manner includes charging the battery by using a PMIC, as shown in fig. 2, the method may include the following steps:
in step S201, the current temperature of the battery is acquired.
In step S202, a target temperature range to which the current temperature belongs is determined from a plurality of preset temperature ranges.
In step S203, the current value corresponding to the target temperature range is set as the charging current.
Wherein, different preset temperature ranges correspond to different current values.
In step S204, the current system consumption current is acquired.
In step S205, a maximum compensation current of the PMIC is determined according to the current system consumption current, a first preset charging efficiency of the charge pump charging, and a second preset charging efficiency of the PMIC charging.
Wherein the maximum compensation current represents a maximum compensation current that the PMIC can provide.
In this step, the maximum compensation current of the PMIC may be obtained by the following maximum compensation current calculation formula:
wherein, I max Is the maximum compensation current, I, of the PMIC 1 For the corresponding charging current, η, of the charge pump at the present temperature 1 Is the first predetermined charging efficiency, η, of the charge pump 2 The second predetermined charging efficiency is the PMIC.
In step S206, the minimum value between the maximum compensation current and the current system consumption current is used as the compensation current.
Considering that the PMIC itself generates heat seriously if the current compensated by the PMIC is too large, the compensation current is the minimum value of the maximum compensation current and the current system consumption current. In order to guarantee that the PMIC can not take place the serious problem of self generating heat and the charge efficiency of battery can not receive the influence, simultaneously, this PMIC can compensate the electric current of battery consumption according to this compensating current, guarantees battery charging current's stability.
In step S207, the battery is charged by the charging current in the first predetermined charging manner, and the battery is charged by the compensating current in the second predetermined charging manner.
In addition, when the first preset charging mode includes charging the battery by using a charge pump, and the second preset charging mode includes charging the battery by using a PMIC to perform compensation charging on the battery, the first supply current may be obtained by calculating a sum of the compensation current and the charging current, and the first supply current is used as a total current required by the battery, that is, the output power requirement transmitted to the charging device for charging the battery, that is, the output power requirement may be the first supply current.
Wherein the first supply current is used for representing a total supply current required by the battery under the condition that the charge pump charges the battery through the charging current and the PMIC charges the battery through the compensation current.
By adopting the method, the second preset charging mode is added to charge the battery in the process of charging the battery by adopting the first preset charging mode, and current compensation is carried out in the charging process, so that the problem of low charging efficiency or heating in the charging process caused by charging only through the first preset charging mode is solved, and the charging efficiency of the battery is not influenced.
In another possible implementation manner, the first preset charging manner includes charging the battery by using the PMIC, and the second preset charging manner includes charging the battery by using the charge pump, as shown in fig. 3, the method may include the following steps:
in step S301, the current charge demand current and the average system consumption current of the battery are acquired.
The average system consumption current is an average value of the total system consumption current in a preset time period.
In step S302, the charging current corresponding to the first preset charging manner is determined according to a current charging demand current of the battery, a first preset charging efficiency of the charge pump, a second preset charging efficiency of the PMIC charging, and the average system consumption current through a second preset current calculation strategy.
The second preset current calculation strategy may include the following first charging current calculation formula, and the charging current corresponding to the first preset charging mode is obtained through the formula:
wherein, I 1 Is a charging current, η, of PMIC (first predetermined charging mode) 1 Is the first predetermined charging efficiency, η, of the charge pump 2 For a second predetermined charging efficiency, I, of the PMIC sys For averaging the system consumption current, I bat The current is required for the current charging of the battery.
In step S303, the compensation current of the second preset charging mode corresponding to the charging current is determined according to the current charging demand current of the battery, the first preset charging efficiency of the charge pump, the second preset charging efficiency of the PMIC charging, and the average system consumption current through a first preset current calculation strategy.
The first preset current calculation strategy may include the following first compensation current calculation formula, and the compensation current corresponding to the second preset charging mode is obtained through the formula:
wherein, I 2 Compensation current, η, for a charge pump (second predetermined charging mode) 1 Is the first predetermined charging efficiency, η, of the charge pump 2 For a second predetermined charging efficiency, I, of the PMIC sys For averaging the system consumption current, I bat The current is required for the current charging of the battery.
In step S304, the battery is charged by the charging current in the first predetermined charging manner, and the battery is charged by the compensation current in the second predetermined charging manner.
In addition, it should be noted that, when the first preset charging mode includes charging the battery by using the PMIC, and the second preset charging mode includes charging the battery by using the charge pump to perform compensation charging on the battery, the total charging demand current of the battery changes, so that the sum of the average system consumption current and the charging demand current can be calculated to obtain a second supply current, and the second supply current is used as the total current required by the battery. That is, the output power supply capability requirement, i.e., the second power supply current, which can be sent to the charging device for charging the battery at this time.
Wherein the second supply current is used to represent a total supply current required by the battery when the PMIC charges the battery through the charging current and the charge pump charges the battery through the compensation current.
Wherein the second supply current may be obtained by the following second supply current calculation formula:
I 0 ＝I sys +I bat
wherein, I 0 For a second supply current, I sys For averaging the system consumption current, I bat The current is currently required for charging the battery.
Accordingly, the charging current corresponding to the first preset charging mode can be further obtained through the following second charging current calculation formula:
wherein, I 1 Is a charging current, η, of PMIC (first predetermined charging mode) 1 Is the first predetermined charging efficiency, η, of the charge pump 2 For a second predetermined charging efficiency, I, of the PMIC 0 A second supply current.
Correspondingly, the compensation current corresponding to the second preset charging mode can be obtained through the following second compensation current calculation formula:
wherein, I 2 Compensation current, η, for a charge pump (second predetermined charging mode) 1 Is the first predetermined charging efficiency, η, of the charge pump 2 For a second predetermined charging efficiency, I, of the PMIC 0 A second supply current.
By adopting the method, the second preset charging mode is added to charge the battery in the process of charging the battery by adopting the first preset charging mode, and current compensation is carried out in the charging process, so that the problem of low charging efficiency or heating in the charging process caused by charging only through the first preset charging mode is solved, and the charging efficiency of the battery is not influenced.
Fig. 4 is a schematic flowchart of another charging control method provided in an embodiment of the present disclosure, where the first preset charging manner includes charging the battery by using a charge pump, and the second preset charging manner includes charging the battery by using a PMIC as an example, and as shown in fig. 4, the method may include the following steps:
in step S401, the current temperature of the battery is obtained, and the charging current corresponding to the charge pump is obtained according to the current temperature of the battery.
In this step, a target temperature range to which the current temperature belongs may be determined from a plurality of preset temperature ranges; and taking the current value corresponding to the target temperature range as the charging current.
In step S402, a current system consumption current is obtained, and a compensation current of the PMIC corresponding to the charging current is obtained according to the current system consumption current.
In one possible embodiment, the compensation current may be identical to the current system consumption current, that is, the current value of the compensation current is equal to the current value of the current system consumption current.
In order to reduce the heating problem during charging of the PMIC, the maximum compensation current of the PMIC can be determined, and then the final compensation current of the PMIC is determined by comparing the maximum compensation current with the current system consumption current.
In step S403, a maximum compensation current of the PMIC is obtained through a maximum compensation current calculation formula according to the charging current.
Wherein, the maximum compensation current calculation formula is as follows:
wherein, I max Is the maximum compensation current, I, of the PMIC 1 Charging current, eta, corresponding to the current temperature of the charge pump 1 Is the first predetermined charging efficiency, η, of the charge pump 2 The second predetermined charging efficiency is the PMIC.
In step S404, it is determined whether the compensation current is greater than or equal to the maximum compensation current.
If the compensation current is greater than or equal to the maximum compensation current, step S405 is performed;
if the compensation current is smaller than the maximum compensation current, step S406 is performed.
In step S405, the maximum compensation current is used as the compensation current.
In step S406, the battery is charged with the charging current by the charge pump, and the battery is charged with the compensation current by the PMIC.
By adopting the method, the second preset charging mode is added to charge the battery in the process of charging the battery by adopting the first preset charging mode, and current compensation is carried out in the charging process, so that the problem of low charging efficiency or heating in the charging process caused by charging only through the first preset charging mode is solved, and the charging efficiency of the battery is not influenced.

Wherein, the first charging current calculation formula is as follows:
wherein, I 1 Is a charging current, η, of PMIC (first predetermined charging mode) 1 Is a first predetermined charging efficiency, η, of the charge pump 2 For a second predetermined charging efficiency, I, of the PMIC sys For averaging the system consumption current, I bat The current is currently required for charging the battery.
