[0038] In the above scheme, temperature information of charging modules corresponding to multiple charging areas of the mobile terminal is obtained. These multiple charging areas are divided according to the heat dissipation distribution information and the distribution information of charging modules in the mobile terminal. Then, based on the temperature information of the charging modules in the first charging area, the area temperature of the first charging area is determined. The first charging area can be any of the multiple charging areas. If the area temperature is greater than or equal to a first temperature threshold, the temperature information of the charging modules in the first charging area is adjusted so that the temperature is lower than the first temperature threshold. In this way, by dividing the mobile terminal into multiple charging areas for temperature monitoring, the local heat generation of the mobile terminal is reflected based on the area temperature of the charging area. When the area temperature is greater than or equal to the first temperature threshold, the heat generation of the corresponding area's charging module is reduced to lower the temperature of that area. This achieves temperature sensing and local charging temperature control of local locations of the mobile terminal, avoiding heat concentration and ensuring charging speed while reducing area temperature.

[0047] Figure 7 This is a block diagram illustrating an apparatus according to an exemplary embodiment. Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0049] Figure 1 This is a flowchart illustrating a mobile terminal charging control method according to an exemplary embodiment, such as... Figure 1 As shown, the mobile terminal charging control method is used in the terminal and includes the following steps.

[0050] In step S13, the temperature information of the charging modules corresponding to multiple charging areas of the mobile terminal is obtained. The multiple charging areas are divided according to the heat dissipation area distribution information of the mobile terminal and the distribution information of the charging modules of the mobile terminal.

[0051] In step S14, the temperature of the first charging region is determined based on the temperature information of the charging module in the first charging region. The first charging region can be any region among multiple charging regions.

[0052] In step S15, if the temperature of the area is greater than or equal to the first temperature threshold, the temperature information of the charging module in the first charging area is adjusted so that the temperature information is less than the first temperature threshold.

[0053] For example, in step S13, in some usage scenarios, the CPU, WIFI, and other functional modules inside the mobile terminal need to work continuously, which can cause the temperature of the corresponding areas to rise. Furthermore, in specific application scenarios, such as when the mobile terminal is running games, engaging in frequent website browsing, or playing videos for extended periods, the corresponding functional modules will rapidly heat up, which is then conducted to the mobile terminal's casing, causing the device to overheat. Therefore, special heat dissipation elements (such as graphite heat dissipation films, VC heat spreaders, etc.) are typically placed in the corresponding areas of the functional modules of the mobile terminal to cover them, ensuring that the functional modules can quickly dissipate heat and avoid abnormal localized overheating during operation. For example, to ensure heat dissipation effectiveness, the coverage area of ​​the heat dissipation elements is usually set to be greater than or equal to the area of ​​a single functional module. Each functional module's corresponding area is equipped with a corresponding heat dissipation element, and to ensure that the heat dissipation elements do not affect each other, the heat dissipation elements are not connected to each other. Optionally, for smaller functional modules, a heat dissipation area can be formed with adjacent functional modules, and a corresponding heat dissipation element can be set to dissipate heat between them. However, in this case, the area of ​​the heat dissipation element cannot exceed a preset value. Furthermore, to avoid heat conduction between functional modules, which could lead to insufficient or even no heat dissipation, the number of functional modules covered by the heat dissipation element is usually no more than three. For example, in practical applications, the CPU and Wi-Fi functional modules of a mobile phone need to cooperate with each other. Typically, the CPU and Wi-Fi functional modules are placed close together in the functional circuit. In this case, a larger heat dissipation element can be set to cover both functional modules for joint heat dissipation, ensuring good heat dissipation performance.

[0054] Understandably, to prevent interference between the charging circuit and the corresponding functional circuits of the functional modules, they are located on different layers within the mobile terminal. Typically, the internal circuitry of a mobile terminal uses a dual-layer motherboard. The charging circuit can be located on the second motherboard, closer to the outer casing, while the functional circuits are located on the first motherboard, closer to the display screen. Isolation components are used to separate the two control circuits to prevent signal interference. The main heat-generating unit in the mobile terminal's charging circuit is the charging IC module. The charging IC has charging management functions, converting different electrical energy input to the mobile terminal (usually expressed as current, voltage, and power) into the rated electrical energy (rated current, rated voltage, and rated power) allowed by the mobile terminal battery through an energy regulation loop. Different charging ICs have different functions, thus meeting different user charging needs.

[0055] The mobile terminal disclosed herein includes multiple charging circuits, each containing one or more charging modules, which may be charging ICs. The charging ICs in different charging circuits operate independently, charging the same battery without interference. Furthermore, each charging IC is positioned at a different location within the charging circuit to prevent localized temperature anomalies caused by concentrated charging IC placement. For example, to prevent the combined heat from the charging ICs and functional modules from overheating the mobile terminal and affecting user experience, the charging ICs and functional modules are typically positioned correspondingly, acting together at a specific location on the mobile terminal's casing. When the temperature at this location reaches a first temperature threshold, the input current of the charging IC can be reduced, and if necessary, the corresponding high-heat charging IC can be shut down, allowing the local temperature of the mobile terminal to return to normal. Therefore, based on the areas defined by the aforementioned heat dissipation elements, corresponding charging circuits can be arranged at the locations corresponding to each heat dissipation element, enabling the same heat dissipation element to simultaneously cool both the charging circuits and functional circuits, ensuring efficient heat dissipation. Understandably, at this point, each functional module has a corresponding charging IC, and the area covered by each charging IC represents a charging area. The coverage area of ​​each charging area can be consistent with the area of ​​the heat dissipation component. Therefore, the multiple heat dissipation areas are the corresponding multiple charging areas.

[0056] Optionally, refer to Figure 2 , Figure 2 A flowchart of a charging area division method provided in an exemplary embodiment of this disclosure, prior to step S13, the method further includes:

[0057] In step S11, the heat dissipation areas corresponding to multiple charging modules are obtained based on the heat dissipation area distribution information.

[0058] In step S12, the charging area is divided according to the heat dissipation area corresponding to the multiple charging modules to obtain multiple charging areas. Among them, the charging modules corresponding to the same heat dissipation area are assigned to the same charging area.

[0059] Understandably, the charging module can be a charging IC. Due to limitations imposed by various hardware modules within the mobile terminal's internal circuitry (e.g., battery module, camera module, earpiece module), the placement of each charging IC is typically fixed. Therefore, the charging area is usually divided based on the distribution of the charging modules and heat dissipation areas. For example, by comparing the area corresponding to multiple charging ICs with the distribution of heat dissipation areas, the heat dissipation area corresponding to each charging IC is determined. Typically, the coverage area of ​​a heat dissipation area is larger than the coverage area of ​​a single charging IC. Therefore, it's easy for different charging ICs to be covered by the same heat dissipation area. In this case, the charging ICs in the same heat dissipation area are grouped into the same charging area.

[0060] Optionally, the area ratio of each charging IC in each heat dissipation area can be determined based on the distribution of multiple charging ICs and multiple heat dissipation areas. For example, the following ratios correspond to the area ratios shown in the table:

[0061] CPU heatsink area WIFI heat dissipation area Heat dissipation area of ​​computing module Charging IC1 40% 10% 0 Charging IC2 35% 20% 10% Charging IC3 0 20% 40% Charging IC4 0 50% 20% ... ... ... ...

[0062] For example, taking the above percentage correspondence table as an example, if the percentage threshold is determined to be 30%, then the percentages of charging IC1 and charging IC2 in the CPU heat dissipation area both reach the threshold. Therefore, charging IC1, charging IC2 and the CPU heat dissipation area are divided into the same charging area. The percentage of charging IC3 in the computing module heat dissipation area is 40%, and no other charging IC in the computing module heat dissipation area reaches the threshold. Therefore, charging IC3 and the computing module heat dissipation area are divided into the same charging area.

[0063] It is understandable that the multiple charging areas obtained by dividing the charging circuit of the mobile terminal according to the above steps include the charging IC and functional modules. The charging IC and functional modules are the main heat-generating units of the mobile terminal. Therefore, the charging area at this time can be understood as the main heat-generating area of ​​the mobile terminal. The internal circuit of the mobile terminal generates heat through heat conduction, causing the corresponding position of the outer shell to continuously heat up. By setting a temperature sensing device in the charging IC, the temperature information of the charging IC can be obtained.

[0064] For example, in step S14, after the various hardware components of the mobile terminal are fixed, under the same charging conditions, the temperature transmitted to the mobile terminal casing by the internal charging IC and heat dissipation components is the same. The casing temperature information detected by the temperature sensor is the temperature information obtained by the combined action of the internal circuitry and heat dissipation components of the mobile terminal on the mobile terminal casing. By setting a temperature sensor at the casing position corresponding to the first charging area in the mobile terminal, the area temperature corresponding to each charging area under different charging environments can be obtained. For example, different charging environment can be simulated experimentally. By detecting the casing temperature at the corresponding position, the mapping relationship between the temperature information of multiple charging modules and the area temperature corresponding to multiple charging areas under different environments can be obtained. Based on the above mapping relationship, the area temperature of the first charging area corresponding to the temperature information of the charging module in the first charging area can be obtained. For example, an NTC (Negative Temperature Coefficient) can be set inside the charging IC. By measuring the resistance of the NTC and applying the correspondence between the resistance coefficient and temperature, the temperature information of the charging IC can be determined. Combining the temperature information of the charging IC and the casing temperature information, the area temperature of the corresponding charging area can be determined.

[0065] Optionally, step S14 above may further include:

[0066] S143, Based on the fitting parameters, obtain the area temperature of the first charging area corresponding to the temperature information of the charging module in the first charging area.

[0067] It is understandable that the shell temperature of a mobile terminal during charging is affected by the internal configuration, distribution of internal circuits, and distribution of heat dissipation areas. Therefore, when the configuration of the mobile terminal is fixed, the temperature information of the internal charging IC and the temperature information of the external area satisfy a certain parameter relationship. By detecting the temperature information of the charging IC and the corresponding area temperature under the same conditions, the correspondence between the internal charging IC temperature and the external area temperature can be obtained. Based on the correspondence, the fitting parameters between the charging IC temperature and the area temperature can be determined according to the data processing method.

[0068] Once the fitting parameters of the mobile terminal are determined, the temperature of the external charging area can be obtained based on the temperature information of the charging IC inside the mobile terminal.

[0069] Optionally, refer to Figure 3 , Figure 3 A flowchart of a method for determining a region temperature provided as an exemplary embodiment of this disclosure, in a first embodiment, prior to the aforementioned step S143, the control method may further include:

[0070] In step S141, multiple shell temperature information and multiple charging module temperature information of the first charging area within a preset time period are obtained. The charging module temperature information is obtained by reading the temperature sensor in the charging module.

[0071] In step S142, the temperature information of multiple charging modules and multiple shell temperatures are fitted to obtain fitting parameters.

[0072] It is understandable that mobile terminals require the use of delicate components for circuit control, thus demanding high temperature sensitivity. Temperature changes within a 1°C range can significantly impact the operational status of some components. Furthermore, elevated internal temperatures in mobile terminals can easily cause internal components to malfunction or even be damaged. Therefore, this disclosure requires precise temperature measurement and calculation to characterize the actual temperature of the internal area of ​​the mobile terminal, thereby controlling the corresponding charging IC temperature. For example, in step S141, to ensure more accurate regional temperatures, the aforementioned temperature sensor is used to repeatedly collect and calculate the casing temperature information within a preset time period, obtaining multiple casing temperature data. Simultaneously, the NTC data inside the charging IC is read, and by referring to the correspondence between resistance and temperature, multiple charging module temperature parameters within the preset time period are obtained.

[0073] In step S142, data fitting is performed on the multiple shell temperature information and multiple charging module temperature information obtained in the above steps. Data fitting is a method of representing data by substituting it into a numerical expression using mathematical methods. The data fitting yields a continuous function curve to represent the known multiple shell temperature information and multiple charging module temperature information. For example, a least-squares squared surface fitting function can be applied to calculate the function values ​​corresponding to the shell temperature information and the charging module temperature information. By reading the function values, the fitting parameters can be obtained. For example, the fitting parameters can be obtained based on the multiple charging module temperature information and multiple shell temperature information using a first formula, which is:

[0074]

[0075] Among them, A n Tshell represents the fitting parameters, where n is the number of temperature acquisitions within a preset time period. n T represents a column matrix consisting of n shell temperature data points obtained from n temperature acquisitions and the corresponding n time points. ntcn This represents the coordinate information formed by the charging module temperature information and the corresponding time point during the nth temperature acquisition by the temperature sensor. For example, to make the obtained fitting parameters more accurate, the preset time is usually set to 40 minutes, and data is acquired once every 30 seconds, collecting the shell temperature and the temperature of the NTC inside the charging IC 80 times, resulting in 80 Tshell shell temperature data points and 80 Tntc charging module temperature data points. These temperature values ​​are then substituted into the above formula to obtain the corresponding fitting parameters.

[0076] Optionally, the region temperature can be obtained using a second formula based on the fitted parameters and temperature information from multiple charging modules. This second formula is:

[0077]

[0078] Among them, Tfit n This represents the area temperature calculated after n temperature acquisitions.

[0079] Understandably, the fitting parameters determined through the above steps, along with the temperature information of the NTC inside the charging IC, can be substituted into the second formula above to calculate and determine the temperature of the area corresponding to the charging region. To enable the mobile terminal to respond quickly to temperature changes, the aforementioned Tshell shell temperature information and T... ntc The charging module temperature information is the highest temperature information at the corresponding time. The area temperature determined based on the above temperature information is used to characterize the highest temperature of the corresponding charging area.

[0080] In step S15, after determining the temperature of the charging area through the above steps, when the area temperature reaches the first temperature threshold, it is necessary to control the temperature of the heating units located within the charging area to decrease. Typically, the internal heating units are the charging IC and functional modules. The heating of the functional modules is mainly due to frequent external user operations, such as playing games, watching videos, and browsing the web. Since user behavior is uncontrollable for mobile terminals, to reduce the internal temperature, the heat output of the charging IC is usually adjusted. For example, the first temperature threshold can be set to 38℃. When the area temperature is greater than or equal to 38℃, the current of the corresponding area's charging IC is adjusted to reduce the area temperature. It is understood that the above-mentioned area temperature detection and charging IC heat output adjustment are performed simultaneously for each charging area. When the area temperature is greater than or equal to the preset temperature value, the heat output of the corresponding area's charging IC is adjusted.

[0081] Optionally, step S15 above may further include:

[0082] In step S151, if the area temperature is greater than or equal to the first temperature threshold, the charging current of the charging module is reduced so as to lower the temperature information of the charging module.

[0083] In step S152, when the temperature information of the charging module reaches the fourth temperature threshold, the mobile terminal is charged based on the corresponding charging current.

[0084] It is understandable that when the temperature of a mobile terminal's area is greater than or equal to a first temperature threshold, it indicates that the temperature of the mobile terminal in that area has reached a dangerous temperature. Maintaining this dangerous temperature can easily harm the operation of the mobile terminal, so temperature reduction measures need to be taken. In this embodiment, the temperature of the area is reduced by decreasing the charging current corresponding to the charging module of the mobile terminal, thereby avoiding abnormal operation of the mobile terminal due to excessive temperature. It is understandable that after the charging current of the charging module corresponding to the charging area decreases, the area temperature will also decrease accordingly. The charging efficiency of the charging module will also decrease as the charging current decreases. Therefore, while ensuring that the area temperature does not have an abnormal impact on the operation of the mobile terminal, it is necessary to ensure the charging efficiency of the charging module. For example, a fourth temperature threshold is set. When the charging current of the charging module decreases and the temperature of the corresponding charging area drops to the fourth temperature threshold, the charging current at this time is maintained to charge the mobile terminal.

[0085] This disclosure, through the above-described embodiments, obtains temperature information of charging modules corresponding to multiple charging areas of a mobile terminal. These multiple charging areas are divided based on the heat dissipation area distribution information and the distribution information of the charging modules of the mobile terminal. Then, based on the temperature information of the charging modules in a first charging area, the area temperature of the first charging area is determined. The first charging area can be any of the multiple charging areas. When the area temperature is greater than or equal to a first temperature threshold, the temperature information of the charging modules in the first charging area is adjusted so that the temperature is less than the first temperature threshold. In this way, by dividing the mobile terminal into multiple charging areas for temperature monitoring, the area temperature of the charging area reflects the local heat generation of the mobile terminal. When the area temperature is greater than or equal to the first temperature threshold, the heat generation of the corresponding area's charging module is reduced to lower the temperature of that area. This achieves temperature sensing and local charging temperature control of local locations of the mobile terminal, avoiding heat concentration and ensuring charging speed while reducing area temperature.

[0086] Optionally, refer to Figure 4 , Figure 4 A flowchart of a mobile terminal charging module scheduling method provided as an exemplary embodiment of this disclosure is included. In the first embodiment described above, the charging control method further includes:

[0087] In step S16, when the temperatures of multiple regions are all greater than or equal to the second temperature threshold, the first target charging region corresponding to the minimum region temperature is obtained.

[0088] In step S17, the first target charging module corresponding to the first target charging area is controlled to charge the mobile terminal.

[0089] For example, when the temperature of the charging area reaches the second temperature threshold, the charging current of the corresponding charging IC decreases. In practical applications, if the user operates too frequently during the charging process, the corresponding functional modules will work frequently, causing the temperature of each charging area to rise to the second temperature threshold. In order to ensure charging safety and charging speed, the charging circuit of the charging IC corresponding to the charging area with the lowest temperature is selected to charge the battery of the mobile terminal, while the charging circuits corresponding to other charging ICs are turned off. For example, the second temperature threshold is set to 40℃. When the temperature of each charging area reaches 40℃, the temperature of each charging area is compared, and the charging circuit corresponding to the charging IC with the lowest temperature is selected for charging.

[0090] Optionally, refer to Figure 5 , Figure 5 A flowchart of another mobile terminal charging module scheduling method provided for an exemplary embodiment of the present disclosure. In the first embodiment described above, the charging control method may further include:

[0091] In step S18, when the temperature of multiple regions is greater than or equal to the third temperature threshold, the second target charging region with the highest charging efficiency is obtained.

[0092] In step S19, the second target charging module corresponding to the second target charging area is controlled to charge the mobile terminal.

[0093] For example, a third temperature threshold is set to 42℃. When the charging temperature of each region is greater than or equal to 42℃, the charging efficiency of each charging IC in that region is obtained. The charging IC with the highest charging efficiency is selected, other charging ICs are turned off, and the charging circuit corresponding to the charging IC with the highest charging efficiency is used to charge the mobile terminal at the fastest possible charging speed, allowing the mobile terminal to quickly reach full charge and exit the charging mode to avoid the temperature effects caused by continuous charging. It is understandable that the charging efficiency of a charging IC is related to its internal adjustment loop. Specifically, the charging efficiency can be determined based on the ratio of input power to output power. For example, a correspondence between charging ICs and their charging efficiencies can be established. By reading the correspondence table, the target charging IC with the highest charging efficiency can be identified.

Figure 6 The mobile terminal charging control device 120 includes: a detection module 121, a determination module 122, and a charging control module 123.
