Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In general, in a charging process, the electronic device needs to set a proper charging current to charge the battery, so that on one hand, damage or influence of an over-large charging current on the electronic device on use of the electronic device by a user is avoided, and on the other hand, influence of an over-small charging current on charging efficiency of the electronic device is avoided.
In practical applications, different types of power adapters can provide different charging currents, for example, a power adapter supporting a fast charging technology can provide a higher charging current, a power adapter not supporting the fast charging technology can provide a lower charging current, and meanwhile, the power adapters supporting different types of fast charging technologies can provide different charging currents, so that it is necessary for an electronic device to set the charging current according to the type of the power adapter into which the electronic device is plugged.
In addition, when setting the charging current, the electronic device needs to fully consider the charging scenario in which the electronic device is located. The charging scenario refers to a software usage status and a hardware usage status of the electronic device that may be affected by or influence the charging process. For example, the charging scene may include software usage states such as playing video, making a call, playing a game, and the like, and the charging scene may also include hardware usage states such as a charging interface temperature, a charging interface resistance, a battery temperature, and the like.
In practical application, due to joule heat generated by the charging current, the electronic device may generate heat during the charging process, when the electronic device is in some software use states, the heat generated by the electronic device due to software operation and the heat generated by charging are overlapped together, which may cause the temperature of the electronic device to exceed national or industrial standards, and because the heat generated by the electronic device due to software operation is different in different software use states, the electronic device generally needs to set the charging current according to the software use state thereof, so as to avoid the over-high temperature of the electronic device.
In addition, in order to ensure the safety compliance of the hardware of the electronic device, the electronic device needs to consider the hardware usage state when setting the charging current.
For example, when the temperature of the charging interface is high, if the charging current is high, the charging interface is likely to be damaged, and a "burning phenomenon" in a popular sense is likely to occur.
For example, when the resistance of the charging interface is small, it indicates that the charging interface is likely to contact with liquid and cause a short circuit, and in this case, if the charging current is large, the charging interface and the electronic device are likely to be damaged.
For example, when the battery temperature is high, if the charging current is large, the battery temperature may be further significantly increased, and the battery may be damaged.
In the related art, the electronic device may call an input current setting function (input _ current _ limit function) to set the charging current, where the input current setting function includes a plurality of first condition determination statements regarding types of power adapters, and through the plurality of first condition determination statements, the input current setting function may finally be located to the type of the power adapter into which the electronic device is inserted.
However, more conditional determination statements may cause a huge volume of the input current setting function, and particularly, the types of the current power adapters and the number of charging scenarios are larger, so that more conditional determination statements are required to locate the types of the power adapters inserted into the electronic device and the charging scenarios where the electronic device is located, which further increases the volume of the input current setting function. The huge volume of the input current setting function affects the execution efficiency of the input current setting function, wastes the computing resources of the electronic equipment, and increases the maintenance difficulty of the input current setting function.
In addition, the way of locating the type of the power adapter and the charging scenario through the condition judgment statement may result in poor expandability of the input current setting function, and in the future, if a new type of the power adapter or a new charging scenario occurs, a technician is required to write the input current setting function again.
In view of the above, embodiments of the present application provide a charging method, which can reduce the volume of an input current setting function, thereby improving the execution efficiency of the input current setting function, saving the computing resources of an electronic device, and reducing the maintenance difficulty of the input current setting function. Besides, the charging method can also increase the expandability of the input current setting function.
In the charging method provided in the embodiment of the present application, the electronic device may obtain a type of a target power adapter into which the electronic device is inserted, and determine a target function pointer pointing to a target current setting table corresponding to the type of the target power adapter, further, the electronic device may determine a target charging scenario in which the electronic device is located, and set a first charging current in the target current setting table according to the target charging scenario, and then, the electronic device may call an input current setting function to obtain the target function pointer through the input current setting function, locate the target current setting table according to the target function pointer, and obtain the first charging current in the target current setting table, and then, the electronic device may charge the battery according to the first charging current, because in the charging method provided in the embodiment of the present application, the input current setting function only needs to obtain the target function pointer, the technical process of positioning the target current setting table according to the target function pointer and acquiring the first charging current from the target current setting table is adopted, so that the input current setting function only needs to comprise a function statement for acquiring the target function pointer and a function statement for acquiring the first charging current from the target current setting table, and does not need to comprise a plurality of condition judgment statements, and therefore, the volume of the input current setting function can be greatly reduced, the execution efficiency of the input current setting function can be improved, the computing resource of electronic equipment is saved, and the maintenance difficulty of the input current setting function is reduced.
In addition, when a new power adapter type or a new charging scene occurs, technicians only need to add a new current setting table corresponding to the new power adapter type and a function pointer pointing to the new current setting table, and modify each current setting table based on the new charging scene, without rewriting an input current setting function, so that the expandability of the input current setting function can be improved.
The charging method provided by the embodiment of the application can be applied to electronic equipment, wherein the electronic equipment can be provided with a battery and a charging control chip, the battery can be a lithium battery, and the charging control chip can be used for controlling the electronic equipment to charge the battery. Optionally, the electronic device may be a notebook computer, a smart phone, a tablet computer, a wearable device, and the like.

As shown in fig. 1, the electronic device includes a processor, a memory, a network interface, a display screen, and an input device connected through a system bus. Wherein the processor of the electronic device is configured to provide computing and control capabilities. The memory of the electronic equipment comprises a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The computer program described above is executed by a processor to implement the charging method provided by the embodiments of the present application. The network interface of the electronic device is used for communicating with an external device through network connection.

Those skilled in the art will appreciate that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration of an electronic device and does not constitute a limitation on the electronic device to which the present solution applies, and that a particular electronic device may include more or less components than those shown, or combine certain components, or have a different arrangement of components.
Referring to fig. 2, a flowchart of a charging method provided in an embodiment of the present application is shown, where the charging method can be applied to the electronic device described above. As shown in fig. 2, the charging method may include the steps of:
step 201, when detecting that the target power adapter is electrically connected, the electronic device obtains the type of the target power adapter, and determines the target function pointer according to the type of the target power adapter.
The electronic device detects that it is electrically connected to the target power adapter, indicating that the electronic device is plugged into the target power adapter and can be charged by the target power adapter, in which case the electronic device may obtain the type of the target power adapter.
Optionally, the electronic device may identify the type of the target power adapter according to a charging protocol, for example, the electronic device may identify the DCP power adapter, the SDP power adapter, and the CDP power adapter according to a BC1.2 charging protocol, for example, the electronic device may identify the QC power adapter according to an HVDCP charging protocol, for example, the electronic device may identify the PD power adapter according to a PD charging protocol, for example, the electronic device may identify a corresponding fast charging power adapter according to a super VOOC charging protocol and a VOOC charging protocol.
After identifying the type of the target power adapter, the electronic device may determine an objective function pointer according to the type of the target power adapter, wherein the objective function pointer points to a target current setting table corresponding to the type of the target power adapter. It should be noted that in the embodiments of the present application, different power adapter types correspond to different current setting tables.
The target charging scene where the electronic device is located refers to a software use state and a hardware use state of the electronic device, wherein the software use state and the hardware use state are influenced by a charging process or influence the charging process, the software use state can include playing videos, making calls, playing games and the like, and the hardware use state can include charging interface temperature, charging interface resistance values, battery temperature and the like.
In general, the electronic device may determine whether itself is in a certain software use state by using a user state, and meanwhile, the electronic device may determine whether itself is in a certain hardware use state according to whether itself is configured with a monitoring program for the certain hardware use state.
After obtaining the target charging scenario in which the electronic device is located, the electronic device may set the first charging current in the target current setting table according to the target charging scenario.
It should be noted that the number of target charging scenarios where the electronic device is located may be multiple, and in an alternative embodiment of the present application, the electronic device may set the first charging current in the target current setting table according to the multiple target charging scenarios.
In an alternative embodiment of the present application, the input current setting function may include a first function statement that obtains a pointer to a target function and a second function statement that obtains the first charging current from a target current setting table.
Based on the first function statement, the input current setting function may implement obtaining a target function pointer, and based on the second function statement, the input current setting function may implement obtaining the first charging current in the target current setting table.
And step 204, the electronic equipment charges the battery according to the first charging current.
After obtaining the first charging current from the target current setting table, the input current setting function may write the first charging current into a preset current register, and the electronic device may read the first charging current from the current register and charge the battery according to the first charging current.
In the charging method provided by the embodiment of the application, the electronic device may obtain the type of the target power adapter into which the electronic device is inserted, determine the target function pointer pointing to the target current setting table corresponding to the type of the target power adapter, further, the electronic device may determine the target charging scenario in which the electronic device is located, set the first charging current in the target current setting table according to the target charging scenario, and then, the electronic device may call the input current setting function to obtain the target function pointer through the input current setting function, position the target current setting table according to the target function pointer, and obtain the first charging current in the target current setting table, and then, the electronic device may charge the battery according to the first charging current, because in the charging method provided by the embodiment of the application, the input current setting function only needs to obtain the target function pointer, the technical process of positioning the target current setting table according to the target function pointer and acquiring the first charging current from the target current setting table is adopted, so that the input current setting function only needs to comprise a function statement for acquiring the target function pointer and a function statement for acquiring the first charging current from the target current setting table, and does not need to comprise a plurality of condition judgment statements, and therefore, the volume of the input current setting function can be greatly reduced, the execution efficiency of the input current setting function can be improved, the computing resource of electronic equipment is saved, and the maintenance difficulty of the input current setting function is reduced.
In addition, when a new power adapter type or a new charging scene occurs, technicians only need to add a new current setting table corresponding to the new power adapter type and a function pointer pointing to the new current setting table, and modify each current setting table based on the new charging scene, without rewriting an input current setting function, so that the expandability of the input current setting function can be improved.
In the following, an alternative technical process for determining the target function pointer by the electronic device according to the type of the target power adapter will be briefly described in the embodiments of the present application, and please refer to fig. 3, where the technical process may include the following steps:
The function pointer table stores the type and state parameters of the power adapter and a plurality of groups of corresponding relations of the function pointers.
It should be noted that the function pointer table stores all types of power adapters that may be plugged into the electronic device.
In each set of corresponding relationships of the function pointer table, the state parameter is used to indicate whether the type of the power adapter corresponding to the state parameter is the type of the target power adapter currently inserted into the electronic device, optionally, the state parameter may include a first value and a second value, the first value is used to indicate that the type of the power adapter corresponding to the state parameter is not the type of the target power adapter currently inserted into the electronic device, the second value is used to indicate that the type of the power adapter corresponding to the state parameter is the type of the target power adapter currently inserted into the electronic device, optionally, the first value may be false, and the second value may be true.
In each group of corresponding relations of the function pointer table, the function pointer points to the current setting table corresponding to the type of the power adapter corresponding to the function pointer.
Please refer to table 1, which illustrates an exemplary function pointer table provided in an embodiment of the present application.
TABLE 1
| Type of power adapter | Status parameter | Function pointer |
| DCP power adapter | false | Func1 |
| …… | …… | |
| QC power adapter | false | Func9 |
As shown in table 1, the state parameter corresponding to the DCP power adapter is false, that is, the state parameter is a first value, which indicates that the type of the target power adapter currently inserted in the electronic device is not the DCP power adapter, and the function pointer Func1 points to the current setting table corresponding to the DCP power adapter.
In step 301, the electronic device may modify the state parameter corresponding to the type of the target power adapter in the function pointer table from a first value to a second value, for example, if the type of the target power adapter currently plugged in the electronic device is a DCP power adapter, the electronic device may modify the state parameter corresponding to the DCP power adapter in the function pointer table from false to true.
It should be noted that, because the electronic device can only be plugged into one target power adapter at a time, but cannot be plugged into a plurality of target power adapters at the same time, at most, only one state parameter of the second value exists in the function pointer table.
In view of the above considerations, in an alternative embodiment of the present application, before executing the technical process of step 301, the electronic device may detect whether the second value already exists in the function pointer table, if the second value already exists, the electronic device may modify the already existing second value into the first value, and execute the technical process of step 301 after the modification is completed, and if the second value does not already exist, the electronic device may directly execute the technical process of step 301. In this way, it is possible to avoid a malfunction of the function logic, which results in an inability to successfully set the first charging current in a subsequent step.
Optionally, in an embodiment of the application, if the electronic device detects that the electrical connection with the target power adapter is disconnected, it is indicated that the target power adapter is unplugged from the electronic device, or the electronic device cannot be charged through the target power adapter, at this time, the electronic device may modify all the second values in the function pointer table to the first values.
And step 302, the electronic equipment takes the function pointer corresponding to the second value in the function pointer table as a target function pointer.
In an alternative embodiment of the present application, the function pointer table may include a special entry, and the electronic device may write the target function pointer into the special entry after determining the target function pointer. Accordingly, the input current setting function may read the target function pointer directly from the special table entry.
As can be seen from the above description, if a new power adapter type occurs, a technician only needs to create a current setting table corresponding to the new power adapter type, create a corresponding relationship of the new power adapter type in the function pointer table, and write a function pointer of the newly created current setting table into the corresponding relationship, without rewriting the input current setting function, so that the expandability of the input current setting function can be improved.
In the following, an optional technical process of the electronic device setting the first charging current in the target current setting table according to the target charging scenario will be described in an embodiment of the present application, please refer to fig. 4, where the technical process may include the following steps:
As described above, the electronic device may be located in a plurality of target charging scenarios, and in step 401, for each target charging scenario, the electronic device may determine a standard charging current corresponding to the target charging scenario according to the type of the target power adapter. The standard charging current corresponding to a certain charging scene refers to the maximum charging current which can ensure the safety compliance of electronic equipment hardware and ensure that the temperature of the electronic equipment does not exceed the national or industrial standard in the charging scene.
Next, the present embodiment will briefly describe a technical process of determining, by an electronic device, a standard charging current corresponding to a certain target charging scenario according to a type of a target power adapter, where the technical process includes the following steps a1 and a 2.
Step a1, the electronic device obtains the scene parameters of the target charging scene.
The scene parameter refers to a parameter for characterizing a charging scene. For example, for the software use state, the scene parameter may be an identifier of the software, a version number of the software, a duration of the software use, and the like, and for the hardware use state, the scene parameter may be a value of the charging interface temperature, a resistance value of the charging interface resistor, a value of the battery temperature, and the like.
Step a2, the electronic device queries a standard charging current meter according to the scene parameters of the target charging scene and the type of the target power adapter, and obtains a standard charging current corresponding to the target charging scene.
The standard charging ammeter stores a plurality of groups of corresponding relations between the type of the power adapter, the scene parameters of the charging scene and the standard charging current.
Please refer to table 2, which shows an exemplary standard charging current meter provided in the embodiments of the present application.
TABLE 2
| Type of power adapter | Scene parameters of charging scene | Standard charging current |
| DCP power adapter | A | 1A |
| …… | …… | |
| QC power adapter | B | 2A |
As shown in table 2, if the type of the target power adapter is a DCP power adapter and the scene parameter of the target charging scenario is a, the electronic device may obtain the standard charging current 1A of the target charging scenario by looking up table 2.
The target current setting table stores a plurality of groups of corresponding relations of the charging scene, the state parameters and the charging current.
It should be noted that all charging scenarios that the electronic device may be in are stored in the target current setting table.
In each group of corresponding relations of the target current setting table, the state parameter is used for indicating whether the corresponding charging scene is the target charging scene in which the electronic device is currently located. Optionally, the state parameter may include a first value and a second value, where the first value is used to indicate that the charging scenario corresponding to the state parameter is not the target charging scenario in which the electronic device is currently located, and the second value is used to indicate that the charging scenario corresponding to the state parameter is the target charging scenario in which the electronic device is currently located, and optionally, the first value may be false, and the second value may be true.
In each set of corresponding relationships of the target current setting table, the charging current may be a maximum current or a minimum current default to a corresponding charging scenario, which is not specifically limited in the embodiment of the present application.
Please refer to table 3, which illustrates an exemplary target current setting table provided in the embodiments of the present application.
TABLE 3
| Charging scenario | Status parameter | Charging current |
| Charging interface temperature | false | 5A |
| …… | …… | |
| Playing video | false | 3A |
As shown in table 3, the state parameter corresponding to the charging interface temperature is false, that is, the state parameter is a first value, which indicates that the charging interface temperature is not the target charging scene where the electronic device is currently located, and the charging current 5A corresponding to the charging interface temperature is the default maximum current.
In step 402, the electronic device may modify the state parameter corresponding to each target charging scene in the target current setting table from a first value to a second value, for example, if the electronic device is in the charging scene of playing a video, the electronic device may modify the state parameter corresponding to the playing video in the target current setting table from false to true.
Meanwhile, the electronic device may modify the charging current corresponding to each target charging scene in the target current setting table by using the standard charging current corresponding to each target charging scene, for example, if the standard current corresponding to the target charging scene of playing the video is 2A, the electronic device may modify 3A in table 3 to 2A.
In step 403, the electronic device sets the minimum charging current in the charging currents corresponding to the second value in the target current setting table as the first charging current.
As shown in table 3, if the state parameter corresponding to the charging interface temperature and the state parameter corresponding to the playing video are both true, that is, both of them are the second values, the electronic device may use the minimum charging current of the charging current 5A corresponding to the charging interface temperature and the charging current 3A corresponding to the playing video in table 3 as the first charging current.
In an alternative embodiment of the present application, the target current setting table may include a special table entry, and the electronic device may write the first charging current into the special table entry after determining the first charging current. Accordingly, the input current setting function may read the first charging current directly from the dedicated entry.
Optionally, in an embodiment of the application, if the electronic device detects that the electrical connection with the target power adapter is disconnected, it is described that the target power adapter is pulled out from the electronic device, or the electronic device cannot be charged through the target power adapter, at this time, the electronic device may modify the charging current corresponding to each charging scenario in the target current setting table to a maximum current or a minimum current default to each charging scenario, and modify all second values in the target current setting table to the first value.
As can be seen from the above description, if a new charging scenario occurs, a technician only needs to create a corresponding relationship of the new charging scenario in each current setting table, and does not need to rewrite the input current setting function, so that the expandability of the input current setting function can be improved.
It is easily understood that, in order to adapt to a change of the target charging scenario, as shown in fig. 5, in an alternative embodiment of the present application, if the electronic device detects that the target charging scenario where the electronic device is located changes, the electronic device may perform the following technical processes:
step 501, the electronic device sets a second charging current in a target current setting table according to the changed target charging scene.
