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.
In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only a subset of the embodiments of the present disclosure, and not all embodiments. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the drawings.
The charging control method provided by the embodiment of the disclosure can be applied to a charging scene of a terminal.
With the technical breakthrough of key links in the field of charging in recent years, the charging power of the terminal is in a rapid and violent situation. However, with the rapid increase of the charging power, the traditional charging scheme and the regulation and control design thereof are increasingly difficult to seek a proper balance pivot in the game of the charging rate and the charging temperature rise, so that the two are in a situation of dual opposition and difficult balance, the charging efficiency is seriously braked, and the use experience of a user is influenced. How to more effectively inhibit the charging temperature rise is one of important factors to be considered in the design link of the current terminal charging scheme.
In the related technology, the temperature of each part of the terminal can be collected, and the temperature fitting is carried out according to the collected temperature to obtain the whole temperature of the terminal. Furthermore, the charging current of the terminal can be subjected to current-limiting control through the temperature of the whole machine. However, in the related art, the charging current of the terminal is subjected to current-limiting control through the temperature of the whole machine, so that better temperature control cannot be realized under the condition of higher temperature rise of a local area of the terminal, and the problem of poorer temperature control effect exists.
In view of this, the present disclosure provides a charging control method, which may determine fitting temperatures of each of a plurality of different areas of a terminal to obtain a plurality of fitting temperatures, and determine a target fitting temperature according to the obtained plurality of fitting temperatures. Further, a current limiting threshold for charging the terminal can be determined through the target fitting temperature, and the charging current of the terminal is controlled by the current limiting threshold. Due to the mode of determining the target fitting temperature in the plurality of fitting temperatures, the comparison and reference are equivalently carried out on the temperature rise conditions of a plurality of different areas of the terminal. Therefore, the current limiting threshold is obtained through the target fitting temperature in the fitting temperatures, so that the current limiting threshold can be adjusted accurately, and the temperature control effect is excellent under the condition of high temperature rise of the local area of the terminal.
Fig. 1 is a flowchart illustrating a charging control method according to an exemplary embodiment, which is used in a terminal as shown in fig. 1, and includes the following steps S11 to S13.
In step S11, the fitting temperatures of the respective regions in the plurality of different regions of the terminal are determined, and a plurality of fitting temperatures are obtained.
In the embodiment of the present disclosure, the plurality of different areas of the terminal may be understood as areas preset for a hardware layout of the terminal. For the resulting plurality of fitting temperatures, each fitting temperature corresponds to one of a plurality of different regions. In other words, the fitting temperature for each region is obtained by temperature fitting the components included in that region. It follows that for a number of different zones, a number of fitting temperatures matching the number of zones can be obtained.
For example, the plurality of different areas of the terminal may include a main board area and a sub board area. Of course, the main board area and the sub board area may be further divided. For example, the main board area may be divided into a main board cold area and a main board hot area according to the usage of the components included in the main board area, and the sub board area may be divided into a sub board cold area and a sub board hot area according to the usage of the components included in the sub board area. The main board cold area is an area where the unusual components in the main board area belong, the main board hot area is an area where the unusual components in the main board area belong, the auxiliary board cold area is an area where the unusual components in the auxiliary board area belong, and the auxiliary board hot area is an area where the usual components in the auxiliary board area belong. For example, for a motherboard area provided with an image capture component, a Central Processing Unit (CPU) and a Graphics Processing Unit (GPU), since the CPU and the GPU are usually common components of a terminal and the image capture component is usually an unusual component of the terminal, the area where the camera is located may be divided into a motherboard cold area and the area where the CPU and the GPU are located may be divided into a motherboard hot area. Based on this, the components included in the mainboard cold area are the CPU and the GPU, and the components included in the mainboard hot area are the image acquisition assembly. In addition, the division manner of the sub-board area is similar to that of the main board area, and is not described herein again. Of course, the terminal may also be divided into regions by other methods, and the methods and the number of the divided regions of the terminal are not specifically limited in this disclosure.
In step S12, a target fitting temperature is determined among the plurality of fitting temperatures.
For example, the target fitting temperature may be obtained by one or more fitting temperatures of the plurality of fitting temperatures that are relatively higher in temperature.
In step S13, a current limit threshold for charging the terminal is determined based on the target fitting temperature, and the charging current of the terminal is controlled at the current limit threshold.
The current-limiting threshold may be understood as an upper threshold of a charging current of the terminal during charging of the terminal, that is, a maximum value of the charging current that can be currently set. For example, the current limiting control of the charging current of the terminal with the current limiting threshold may be to control the terminal to be charged with the charging current less than or equal to the current limiting threshold.
According to the charging control method provided by the embodiment of the disclosure, temperature fitting can be performed on a plurality of different areas of the terminal, the target fitting temperature is determined according to a plurality of fitting temperatures obtained through fitting, the current limiting threshold value for performing current limiting control on the terminal is determined according to the target fitting temperature, and the charging current of the terminal is subjected to current limiting control according to the current limiting threshold value. The determined target fitting temperature is determined through the fitting temperature corresponding to each area in the plurality of different areas of the terminal, so that the method is equivalent to taking the actual temperature rise conditions of the plurality of different areas of the terminal as reference, and the local temperature rise conditions of the terminal are finely judged according to the actual temperature rise conditions. The method can improve the setting precision of the current limiting threshold value, and further improve the temperature control effect of the terminal in the charging process.
In addition, it can be understood that the charging control method provided by the embodiment of the present disclosure may be implemented in any time node in the terminal charging process, in a manner of determining the current limit threshold and performing charging control through the current limit threshold. For example, the current limit threshold adjustment and the current control may be performed synchronously in the case where it is monitored that the terminal enters the charging state. For another example, the current limiting threshold adjustment and the current control may be performed when it is monitored that the terminal is charged for a specified time period. Based on this, can satisfy the different user demand that aim at terminal charging scene.
In the embodiment of the present disclosure, each region includes a component, which may include a component disposed in the region, or may include a component that is not disposed in the region but has an influence on a temperature rise of the region. For example, a CPU provided in the main board region may be a component included in the main board region, a battery which is not provided in the main board region but has an influence on a temperature rise in the main board region may be a component included in the main board region, or both of them may be components included in the main board region. The temperature fitting is carried out on the plurality of different areas of the terminal by the components obtained in the mode, so that the fitting temperature of each area can be more fit with the actual temperature of each area, and the calculation accuracy of the fitting temperature is improved.
Illustratively, the area includes components such as a CPU, GPU, backlight assembly, image capture assembly, battery, Integrated Circuit (IC), and/or Universal Serial Bus (USB). The present disclosure does not specifically limit the types and numbers of components included in the regions.
For example, for a motherboard area including a CPU, GPU and battery, and for a USB and battery subplate area, the T may be passedmain=(WcpuTcpu+WbattTbatt)·CmainDetermine the fitting temperature of the main board area (example with T)mainRepresents) and by T), andsub=(WusbTusb+W′battTbatt)·Csubdetermine the fitting temperature of the subplate area (example with T)subRepresentation). Wherein, WcpuRepresents the weight corresponding to the CPU in the motherboard region, WbattRepresenting the corresponding weight of the battery in the motherboard area, WusbRepresents the weight, W ', corresponding to USB in the slave board area'battRepresenting the corresponding weight, T, of the cells in the sub-panel regioncpuIndicating the temperature, T, of the CPUbattIndicating the temperature, T, of the batteryusbIndicating the temperature of the USB. Furthermore, CmainFitting temperature compensation coefficient, C, representing the main board areasubThe fitted temperature compensation coefficient for the sub-panel area is shown.
For example, the target fitting temperature may be determined from the plurality of fitting temperatures in the following manner. For convenience of description, the fitting temperature with the highest temperature among the plurality of fitting temperatures is referred to as a first fitting temperature, and the fitting temperature having a temperature difference from the first fitting temperature smaller than a preset temperature difference is referred to as a second fitting temperature.
FIG. 2 is a flowchart illustrating a method for determining a target fitting temperature among a plurality of fitting temperatures, as shown in FIG. 2, including the following steps, according to an exemplary embodiment.
In step S21, a first fitting temperature having the highest temperature among the plurality of fitting temperatures is determined.
It is to be understood, among others, that the first fitting temperature determined may be one or more.
In step S22, it is determined whether there is a second fitting temperature among the plurality of fitting temperatures having a temperature difference from the first fitting temperature that is smaller than a preset temperature difference.
In step S23a, if the second fitting temperature exists, the first fitting temperature and the second fitting temperature are fitted to obtain a target fitting temperature.
In the embodiment of the present disclosure, the temperature difference from the first fitting temperature is smaller than the second fitting temperature of the preset temperature difference, which may be one or more.
For example, fitting the first fitting temperature and the second fitting temperature may be understood as fitting each of the first fitting temperature and the second fitting temperature. For example, if there is a first fitting temperature TaAnd is present with TaA second fitting temperature T with a temperature difference smaller than the preset temperature differenceb1And Tb2Then can be to Ta、Tb1And Tb2And fitting to obtain the target fitting temperature.
The same or different fitting weights can be set for the first fitting temperature and the second fitting temperature used for fitting calculation according to actual use requirements. In one embodiment, when it is determined that the second fitting temperature exists, the same fitting weight may be set for each of the first fitting temperatures and the second fitting temperatures, and the first fitting temperature and the second fitting temperature may be fitted with the same weight. For example, if the target fitting temperature includes a fitting temperature corresponding to the main board region and a fitting temperature corresponding to the sub board region, and it is determined that the fitting temperature of the main board region is the first fitting temperature and the fitting temperature corresponding to the sub board region is the second fitting temperature, fitting weights of 1/2 may be set for the fitting temperature corresponding to the main board region and the fitting temperature corresponding to the sub board region, respectively, so as to perform fitting, thereby obtaining the target fitting temperature. Of course, the fitting process described above may also be understood as calculating a temperature average of a plurality of fitting temperatures, such as calculating a temperature average of a first fitting temperature and a second fitting temperature. In addition, the weights of the fitting temperatures in the first fitting temperature and the second fitting temperature can be set to be different according to actual use requirements, and the weight setting mode of fitting through the first fitting temperature and the second fitting temperature is not particularly limited in the present disclosure.
In step S23b, if the second fitting temperature is not present, the first fitting temperature is set as the target fitting temperature.
According to the charging control method provided by the embodiment of the disclosure, the first fitting temperature with the highest temperature can be determined, the second fitting temperature is screened through the preset temperature difference value, and the target fitting temperature is determined. The target fitting temperature obtained by the method can represent the current temperature rise condition of one or more areas with higher temperature rise. Further, a current limit threshold for current limit control of the terminal may be determined by the determined target fitting temperature.
As an example, the terminal includes a main board area and a sub board area, and a process of performing current limiting control on the terminal is described below.
Fig. 3 is a flowchart illustrating a current limiting control of a terminal with respect to a main board area and a sub board area of the terminal according to an exemplary embodiment.
For example, as shown in fig. 3, temperature fitting may be performed on components included in the terminal main board region to obtain a main board fitting temperature, and temperature fitting may be performed on components included in the terminal sub board region to obtain a sub board fitting temperature. Furthermore, the temperature value of the fitting temperature of the main board can be compared with that of the auxiliary board, and the target fitting temperature can be determined through a preset temperature difference value. For example, the target fitting temperature may be determined by a temperature difference between the main board fitting temperature and the sub board fitting temperature. For example, if the fitting temperature of the main board is higher than the fitting temperature of the auxiliary board, and the temperature difference between the fitting temperature of the main board and the fitting temperature of the auxiliary board is greater than the preset temperature difference, the fitting temperature of the main board may be determined as the target fitting temperature. For another example, if the sub-board fitting temperature is higher than the main board fitting temperature, and the temperature difference between the sub-board fitting temperature and the main board fitting temperature is greater than the preset temperature difference, the sub-board fitting temperature may be determined as the target fitting temperature. For another example, if the temperature difference between the fitting temperature of the main board and the fitting temperature of the auxiliary board is less than or equal to the preset temperature difference, the fitting temperature of the main board and the fitting temperature of the auxiliary board may be fitted to obtain the target fitting temperature. Further, a current limiting threshold value can be determined through the target fitting temperature, and the charging current of the terminal is subjected to current limiting control through the current limiting threshold value.
Generally, the charging scene of the terminal may include, for example, a screen-off charging scene, a photo charging scene, an internet charging scene, a game charging scene, and/or a video playing charging scene. Because the service conditions of all the components of the terminal are usually different for different charging scenes, the temperature rise conditions of the same component for different charging scenes are usually different.
For example, the corresponding relationship between the charging scene and the weight may be stored in advance, and when the current charging scene of the terminal is determined, the weight matching the current charging scene is obtained through the corresponding relationship between the charging scene and the weight, and then the fitting temperature of each of the plurality of different regions is determined through the weight matching the current charging scene. Further, one or more target fitting temperatures may be determined among the plurality of fitting temperatures for determining the current limit threshold. For convenience of description, the weight matched with the current charging scenario is referred to as a first weight, and the temperature rise parameter obtained by the target fitting temperature and the target reference temperature matched with the target fitting temperature is referred to as a first temperature rise parameter.
Fig. 4 is a flowchart illustrating a method for determining a current limit threshold for charging a terminal based on a target fitting temperature according to an exemplary embodiment, as shown in fig. 4, including the following steps S31 to S34.
In step S31, a first weight matching the current charging scenario is determined based on the correspondence between the charging scenario and the weight, and a plurality of fitting temperatures are obtained by determining a fitting temperature for each of a plurality of different regions of the terminal with the first weight.
In the embodiment of the present disclosure, the correspondence between the charging scenario and the weight may be created and stored in advance. For example, for a plurality of different charging scenarios of the terminal, a corresponding weight may be preset for each charging scenario, and a corresponding relationship between the charging scenario and the weight may be created. For example, if the plurality of different areas of the terminal include a main board area and a sub board area, the main board area includes a CPU, a GPU and an image capture component, and the sub board area includes a battery and a USB. The weight W may be set for the CPU for charging scenario AA1Setting the weight W for the GPUA2Setting a weight W for the image acquisition componentA3Setting a weight W for the batteryA4Setting the weight W for USBA5. Based on this, a charging scenario A and a weight W may be createdA1Weight WA2Weight WA3Weight WA4And a weight WA5Corresponding relation between the charging scene and the charging scene W when the current charging scene of the terminal is determined to be the charging sceneAImmediate invocation of weight WA1To a weight WA5. Here, it can be understood that the sum of the assigned weights for the components of each region is 1. For example, for a motherboard area, WA1+WA2+WA31. For another example, for the sub-panel area, WA4+WA51. It can be understood that, for different charging scenarios, the weights corresponding to the components included in the main board area are different, and the weights corresponding to the components included in the sub board area are also different. For example, in the above manner, for a plurality of different charging scenarios, the corresponding relationship between the charging scenario and the weight is respectively created and stored, so that the terminal can call the corresponding weight according to the charging scenario in the charging process.
Go toIn the step of charging control of the terminal, the corresponding relation between the charging scene and the weight can be called according to the actual use requirement. For example, if the plurality of different areas of the terminal include a main board area and a secondary board area, the main board area includes a CPU, a GPU and an image capture component, the secondary board area includes a battery and a USB, and the current charging scene of the terminal is charging scene a, a first weight matching the current charging scene may be determined according to a pre-stored correspondence between the charging scene and the weight (for example, if the current charging scene is charging scene a, the first weight includes weight WA1Weight WA2Weight WA3Weight WA4And a weight WA. Wherein the weight WA1Is the weight of the CPU, weight WA2Is the weight of the GPU, weight WA3Is the weight of the image acquisition component, weight WA4Is the weight of the battery, the weight WA5Weight of USB). Based on this, can pass Tmain=(WA1Tcpu+WA2Tgpu+WA3Tcam)·CmainBy determining the fitting temperature (exemplified by T) of the main board areamainIs represented by the formula) in which TcpuIndicating the temperature, T, of the CPUgpuRepresenting the temperature, T, of the GPUcamRepresenting the temperature of the image-capturing component, CmainThe fitted temperature compensation coefficient for the main board area is represented.

In this case, fitting temperatures corresponding to respective areas in the plurality of different areas may be obtained (for example, in the case where the terminal includes the main board area and the sub board area, the plurality of different fitting temperatures include the fitting temperature T of the main board areamainAnd fitting temperature T of the sub-plate regionsub)。
In step S32, a target fitting temperature is determined among the plurality of fitting temperatures.
In the embodiments of the present disclosure, the implementation of determining the target fitting temperature by using a plurality of fitting temperatures has been described in the above embodiments, and reference may be made to any of the above embodiments for relevant contents.
In step S33, a target reference temperature matching the target fitting temperature is determined based on the correspondence between the target fitting temperature and the reference temperature, and a first temperature rise parameter of the target fitting temperature is determined from the target fitting temperature and the target reference temperature.
Wherein the reference temperature is used to determine a degree of temperature rise of the terminal. For example, a corresponding relationship between the target fitting temperature and the reference temperature may be preset and stored, and the target reference temperature matching the target fitting temperature is searched for according to the corresponding relationship, so as to obtain the current heating degree corresponding to the region matching the target fitting temperature. And the corresponding relation between the target fitting temperature and the reference temperature is a one-to-one matching corresponding relation. In other words, one target fitting temperature corresponds to one reference temperature.
In the embodiment of the disclosure, the first temperature-rise parameter may be obtained by dividing the target fitting temperature by the target reference temperature according to a ratio between the target fitting temperature and the target reference temperature.
In step S34, a current limiting threshold of the terminal is adjusted according to the first temperature-rise parameter, so as to obtain a current limiting threshold for charging the terminal.
For example, the current limit threshold adjustment of the maximum current limit threshold of the terminal may be implemented by determining a product value between the first temperature-rise parameter and the maximum current limit threshold, and using the obtained product value as the current limit threshold for charging the terminal.
By the charging control method provided by the embodiment of the disclosure, under the condition that the current charging scene is determined, the fitting temperature of each area in a plurality of different areas is calculated through the first weight matched with the current charging scene, and then the target fitting temperature is determined through the plurality of fitting temperatures. The target fitting temperature obtained by the method is fit with the actual temperature rise condition of the current charging scene of the terminal, and the method has high precision. Based on the method, the current limiting threshold value for charging the terminal is determined by matching the target fitting temperature of the current charging scene, so that the precision of the current limiting threshold value can be ensured, and the temperature control effect of the terminal is improved.
In another embodiment, the fitting temperature calculation may be performed on each of the plurality of different regions by using a preset default calculation weight, so as to determine a plurality of fitting temperatures, and determine the target fitting temperature by using the plurality of fitting temperatures. Further, in a case that a current charging scenario of the terminal is determined, a current scenario correction parameter matching the current charging scenario may be determined according to a corresponding relationship between the charging scenario and the scenario correction parameter (for example, the current scenario correction parameter matching the current charging scenario represents a temperature difference between a target fitting temperature calculated by a default weight and a target fitting temperature calculated by a first weight, where the first weight is a weight matching the current charging scenario). Furthermore, the temperature of the obtained target fitting temperature can be corrected through the current scene correction parameters, and then the current limiting threshold value is determined according to the corrected target fitting temperature.
For example, the correspondence between the charging scenario and the scenario modification parameter may be predetermined as follows, so that the terminal may invoke the correspondence in the subsequent charging process. For convenience of description, the preset default calculation weight is referred to as a second weight, the fitting temperature of each of a plurality of different regions of the terminal determined based on the weight matching the charging scene is referred to as a fifth fitting temperature, the fitting temperature obtained by fitting the plurality of fifth fitting temperatures is referred to as a third fitting temperature, the fitting temperature of each of the plurality of different regions of the terminal determined based on the second weight is referred to as a sixth fitting temperature, and the fitting temperature obtained by fitting the plurality of sixth fitting temperatures is referred to as a fourth fitting temperature.
Fig. 5 is a flowchart illustrating a method of creating a correspondence between charging scenes and scene correction parameters according to an exemplary embodiment, as shown in fig. 5, including the following steps S41 to S43.
In step S41, a third fitting temperature and a fourth fitting temperature corresponding to the charging scenario are determined.
For example, the determined charging scenario may include a screen-off charging scenario, a photo charging scenario, a web charging scenario, a game charging scenario, and/or a video playback charging scenario, for example.
In the embodiment of the disclosure, the fifth fitting temperature is a fitting temperature of each of a plurality of different regions of the terminal determined based on the weight of the matched charging scene, the sixth fitting temperature is a fitting temperature of each of a plurality of different regions of the terminal determined based on the second weight, the third fitting temperature is obtained by fitting a plurality of fifth fitting temperatures, and the fourth fitting temperature is obtained by fitting a plurality of sixth fitting temperatures. The manner of determining the fifth fitting temperature or the sixth fitting temperature is the same as the manner of determining the fitting temperatures of multiple different areas of the terminal in the above embodiments, and reference may be made to any of the above embodiments for relevant contents. In addition, the manner of fitting the fifth fitting temperature to obtain the third fitting temperature, or the manner of fitting the sixth fitting temperature to obtain the fourth fitting temperature is the same as the manner of determining the target fitting temperature among the plurality of fitting temperatures in the above embodiment, and reference may be made to any of the above embodiments for related contents.
For example, taking the fitting of the fifth fitting temperatures to obtain the third fitting temperature as an example, the fitting temperature with the highest temperature may be determined among the plurality of fifth fitting temperatures, and the other fitting temperatures except for the fitting temperature with the highest temperature among the fifth fitting temperatures may be screened through the preset temperature difference. And if the temperature difference value between the fitting temperature with the highest temperature and other fitting temperatures with the preset temperature difference value is smaller than the other fitting temperatures, fitting the other fitting temperatures and the fitting temperature with the highest temperature to obtain a third fitting temperature. In addition, it can be understood that if there is no other fitting temperature having a temperature difference value with the fitting temperature having the highest temperature that is smaller than the preset temperature difference value, the fitting temperature having the highest temperature may be directly used as the third fitting temperature.
In the embodiment of the present disclosure, the second weight may be preset. Illustratively, if the plurality of different areas of the terminal include a main board area and a sub board area, andthe main board area comprises a CPU, a GPU and an image acquisition assembly, and the auxiliary board area comprises a battery and a USB. Can be realized by setting weight W for CPUB1Setting the weight W for the GPUB2Setting a weight W for the image acquisition componentB3Setting a weight W for the batteryB4And setting the weight W for the USBB5In the method of (1), a second weight is set for each component of the terminal. Further, the temperatures of the CPU, the GPU, the image acquisition assembly, the battery and the USB can be determined respectively, and the temperature can be passed through T with a second weightmain=(WB1Tcpu+WB2Tgpu+WB3Tcam)·CmainBy determining the fitting temperature (exemplified by T) of the main board areamainIs represented by the formula) in which TcpuIndicating the temperature, T, of the CPUgpuRepresenting the temperature, T, of the GPUcamIndicating the temperature of the image-capturing component, CmainThe fitted temperature compensation coefficient for the main board area is represented.

Based on this, a fitting temperature calculated with the second weight (exemplary, including the fitting temperature T of the main board region) can be obtainedmainAnd fitting temperature T of the sub-plate regionsub) Subsequently, a fourth fitting temperature may be determined by calculating the fitting temperature of each region by the second weight. For example, a preset weight of any charging scene may be used as the second weight, and for example, a weight corresponding to a screen-off charging scene may be used as the second weight. Of course, the second weight may be set separately, and the setting manner of the second weight is not particularly limited in this disclosure.
In step S42, scene correction parameters are determined according to the third fitting temperature and the fourth fitting temperature.
For example, a ratio between the third fitting temperature and the fourth fitting temperature may be used as a temperature difference between the third fitting temperature and the fourth fitting temperature, and then the scene correction parameter is determined according to the temperature difference, that is, the scene correction parameter is determined according to the third fitting temperature and the fourth fitting temperature. For example, for a third fitting temperature (e.g., represented by T1) and a fourth fitting temperature (e.g., represented by T2), the ratio between the third fitting temperature and the fourth fitting temperature, i.e., the temperature difference between the third fitting temperature and the fourth fitting temperature (e.g., represented by T1/T2), may be represented by T1/T2.
For example, the ratio between the third fitting temperature and the fourth fitting temperature obtained by the above embodiments may be used as a scene correction parameter, and a correspondence relationship between the charging scene and the scene correction parameter may be created.
In step S43, a correspondence relationship between the charging scene and the scene correction parameter is created.
The charging control method provided in the embodiment of the present disclosure performs the above steps S41 to S43 for a plurality of different charging scenarios, so as to obtain a plurality of sets of correspondence relationships between the charging scenarios and the scenario correction parameters (for example, the correspondence relationship between the current charging scenario and the current scenario correction parameters may be understood as one set of correspondence relationship among the plurality of sets of correspondence relationships). Further, under the condition that the current charging scene of the terminal is determined, the corresponding relation between the charging scene and the scene correction parameter can be called, so that the current scene correction parameter matched with the current charging scene is determined, and the current limiting threshold value for controlling the charging current of the terminal under the current charging scene is determined.
Further, in the case where the correspondence between the charging scenario and the scenario correction parameter is obtained in the above manner, the current limit threshold for controlling the charging current of the terminal may be determined in the following manner.
Fig. 6 is a flowchart illustrating another method for determining a current limit threshold for charging a terminal based on a target fitting temperature according to an exemplary embodiment, as shown in fig. 6, including the following steps S51 to S54.
In step S51, the fitting temperature of each of the plurality of different regions of the terminal is determined with a preset second weight, a plurality of fitting temperatures are obtained, and a target fitting temperature is determined among the plurality of fitting temperatures.
In the embodiment of the present disclosure, the setting manner of the second weight and the implementation manner of determining the fitting temperature of each of the plurality of different areas of the terminal through the second weight are described in the above embodiments, and are not described herein again.
In step S52, a current scene correction parameter corresponding to the current charging scene is determined based on the correspondence between the charging scene and the scene correction parameter, and the target fitting temperature is subjected to temperature correction based on the current scene correction parameter, so as to obtain a corrected target fitting temperature.
For example, the corresponding relationship between the current scene and the current scene correction parameter may be determined in the pre-stored corresponding relationship between the plurality of sets of charging scenes and the scene correction parameter, and the current scene correction parameter corresponding to the current charging scene may be obtained through the corresponding relationship between the current scene and the current scene correction parameter.
In the embodiment of the disclosure, the corrected target fitting temperature can be obtained through a product value between the target fitting temperature and the current scene correction parameter, so that the temperature correction of the target fitting temperature is realized.
In step S53, a target reference temperature matching the target fitting temperature is determined based on the correspondence between the target fitting temperature and the reference temperature, and a second temperature rise parameter of the corrected target fitting temperature is determined from the corrected target fitting temperature and the target reference temperature.
For example, a corresponding relationship between the target fitting temperature and the reference temperature may be preset and stored, and the target reference temperature matching the target fitting temperature is searched for according to the corresponding relationship, so as to obtain the current heating degree corresponding to the region matching the target fitting temperature. And the corresponding relation between the target fitting temperature and the reference temperature is a one-to-one matching corresponding relation. In other words, one target fitting temperature corresponds to one reference temperature.
In the embodiment of the disclosure, the second temperature rise parameter can be obtained by a product value between the corrected target fitting temperature and the target reference temperature.
In step S54, the maximum current limiting threshold of the terminal is adjusted by the second temperature rise parameter, so as to obtain a current limiting threshold for charging the terminal.
For example, the current-limiting threshold for charging the terminal may be obtained by a product value between the second temperature rise parameter and the maximum current-limiting threshold of the terminal, so as to implement current-limiting threshold adjustment on the maximum current-limiting threshold of the terminal.
In the embodiment of the disclosure, the target fitting temperature may be calculated by using the preset second weight, and then the calculated target fitting temperature may be subjected to temperature correction by matching the scene correction parameter of the current charging scene. In the process, the target fitting temperature is determined through the preset second weight, and the terminal does not need to wait for determining the current charging scene, so that the time consumption of the whole process can be reduced, and the adjusting efficiency of the current limiting threshold is improved.
In the embodiment of the present disclosure, the correspondence between the target fitting temperature and the reference temperature may be predetermined as follows. For example, a reference temperature for adjusting the current limit threshold may be preset (for example, if the target fitting temperature of the terminal is less than or equal to the reference temperature, the terminal controls the charging current through the maximum current limit threshold, and if the target fitting temperature of the terminal is greater than the reference temperature, the terminal starts to adjust the current limit threshold, and the adjusted current limit threshold is less than the maximum current limit threshold). In addition, target fitting temperatures corresponding to various conditions in the various temperature rise conditions in a one-to-one manner can be respectively determined according to the various different temperature rise conditions of the terminal, so that a plurality of different target fitting temperatures can be obtained. For each target fitting temperature in the plurality of different target fitting temperatures, a temperature difference between the target fitting temperature and the reference temperature may be determined, respectively, to obtain a plurality of different temperature differences. Further, a reference temperature matched thereto may be set for each of a plurality of different temperature difference values, respectively (for example, one reference temperature matched thereto may be set for one temperature difference value). Based on this, for each target fitting temperature, there is one reference temperature, and through a plurality of sets of correspondence relationships between the target fitting temperatures and the reference temperatures (one set of correspondence relationships corresponds to one target fitting temperature and the first reference temperature), the correspondence relationship between the target fitting temperatures and the reference temperatures can be obtained.
The setting mode of the reference temperature is matched with the actual use requirement aiming at the reference temperature. For example, in the embodiment of the present disclosure, the temperature rise parameter is obtained by using a ratio between the target fitting temperature and the target reference temperature, and the current limiting threshold for charging the terminal is obtained by using a product value between the temperature rise parameter and the maximum current limiting threshold. Therefore, the reference temperature needs to have a larger variation range than the target fitting temperature, so that in case the target fitting temperature increases, the ratio between the target fitting temperature and the target reference temperature can be reduced to match the larger target fitting temperature with the smaller current limit threshold. Or in the case of a decrease in the target fitting temperature, the ratio between the target fitting temperature and the target reference temperature may be increased so that a smaller target fitting temperature matches a larger current limit threshold. Also, it may be understood that, in order that the terminal may control the charging current through the maximum current limiting threshold in a case where a temperature difference between the target fitting temperature and the reference temperature is 0, the temperature between the target fitting temperature and the target reference temperature may be set to be the same for the target fitting temperature less than or equal to the reference temperature. Based on this, when the target fitting temperature is less than or equal to the reference temperature, the temperature rise parameter (the ratio between the target fitting temperature and the target reference temperature, or the ratio between the corrected target fitting temperature and the target reference temperature) is 1, and the product value between the temperature rise parameter and the maximum current limiting threshold is still the maximum current limiting threshold, so that the terminal can control the charging current through the maximum current limiting threshold.
In the above embodiment, since the reference Temperature is set based on the Temperature difference between the target fitting Temperature and the reference Temperature, and the determination process of the target reference Temperature may be implemented by using a preset Model (for example, the corresponding relationship between the target fitting Temperature and the reference Temperature is introduced into the preset Model, so that the Model may output the corresponding target reference Temperature when the target fitting Temperature of the input Model is obtained), the reference Temperature may also be referred to as a Model Temperature Gradient (MTG). In addition, since the Scene correction parameter is obtained by a ratio between the first target fitting temperature and the second target fitting temperature, the Scene correction parameter can also be understood as a Scene Proportion Threshold (SPT) for characterizing that the Scene correction parameter is the ratio between the first target fitting temperature and the second target fitting temperature.
For example, the correspondence between a plurality of sets of charging scenes matching a plurality of different charging scenes and scene correction parameters may be stored in advance, and the correspondence between the target fitting temperature and the reference temperature may be stored in advance. On the basis, the fitting temperature of each of a plurality of different areas of the terminal can be determined through the preset second weight, so that a plurality of fitting temperatures are obtained, and the target fitting temperature (shown as T' in an example) is determined in the plurality of fitting temperatures. In this case, the current charging scenario may be determined to obtain the scenario modification parameters (example denoted as SPT) matching the current charging scenario. Furthermore, temperature correction of the target fitting temperature can be realized in a T' SPT mode, and the corrected target fitting temperature is obtained. Further, a target reference temperature (for example, MTG) corresponding to the target fitting temperature can be obtained through a pre-stored correspondence between the target fitting temperature and the reference temperature, and then
