[0046] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0047] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0048] Figure 1 FIG. 1 is a flow chart of a terminal charging control method according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0049] In step S101, if it is determined that the terminal is in a screen-on state while charging and the terminal is equipped with a protective case, the terminal is controlled to charge with a second current until the temperature at the first position of the terminal reaches a temperature threshold.

[0050] Among them, when the terminal is equipped with a protective case, the first position is in the area covered by the protective case, the second current is greater than the first current, the first current is the charging current of the terminal in the screen-off state, and the temperature threshold is greater than the temperature when the charging current starts to decrease when the terminal is charging in the screen-off state.

[0051] The terminal may be, for example, a mobile phone, a tablet computer, etc. The charging mode of the terminal may include a wired mode or a wireless mode.

[0052] In the related art, a safety limit temperature is usually set for safety considerations. When the temperature of the terminal during charging reaches the safety limit temperature, the charging current is controlled to decrease.

[0053] In this solution, the first position is one or more positions in the area covered by the protective shell when the terminal is equipped with a protective shell. For example, it can be one or more positions on the back of the terminal, or one or more positions on the side of the terminal, or one or more positions on the back and side of the terminal. Exemplarily, a negative temperature coefficient (NTC) sensor can be used to obtain the temperature of the first position. The temperature threshold is the maximum temperature allowed to be reached by the first position when the terminal is equipped with a protective shell and is in the screen-on state during charging with the second current.

[0054] The first current is the initial charging current when the terminal is charging in the screen-off state (for example, it can be 6A). When the terminal is in the screen-off state, it can be considered that the user is not currently using the terminal, the demand for charging speed is low, the initial charging current is small, and the terminal temperature limit value when the charging current starts to decrease is low. The terminal temperature limit value is that when the temperature of the terminal reaches the terminal temperature limit value, for safety reasons, the charging current is controlled to start decreasing to avoid the terminal temperature from being too high. The second current is a charging current that is larger than the first current.

[0055] Whether the terminal is in the screen-on state can be determined by detecting whether the operating current of the display screen reaches the operating current in the screen-on state. When the terminal is in the screen-on state, it is considered that the user is using the terminal. In the screen-on state, the terminal consumes a lot of power and has a high demand for charging speed. In addition, when equipped with a protective case, the heat dissipation capacity of the terminal is reduced, and the temperature rise at the first position is faster than charging in the screen-off state. When the terminal is in the screen-on state and is equipped with a protective case for charging, if the charging current is still limited according to the terminal temperature limit value in the screen-off state, the charging current will be limited very quickly, making the charging slower.

[0056] In addition, when using a terminal with a protective case, the user is not very aware of the terminal's temperature. When the terminal temperature is high, the user will feel only a slight fever. However, when the terminal has actually reached the terminal temperature limit and the charging current is limited, the user may not notice this and will only feel that the charging is slow, mistakenly believing that the terminal's performance is poor.

[0057] This solution sets a second current and temperature threshold under the premise of taking safety into consideration. Compared with the screen-off state, when the terminal is in the screen-on state and equipped with a protective case, the charging current of the terminal is larger, and the terminal temperature limit value for limiting the charging current is higher. This solution adopts different charging strategies for different scenarios in which the terminal is located. When the terminal equipped with a protective case is charging and running at the same time, a larger charging current and a higher terminal temperature limit value are adopted to avoid limiting the charging current too early. In this way, the charging strategy of the terminal is flexibly switched according to the charging scenario. On the one hand, it meets the user's demand for fast charging of the terminal when using the terminal. On the other hand, it avoids the user from not perceiving that the terminal has reached a high temperature due to the heat insulation effect of the protective case, and mistakenly believes that the charging has not slowed down, thereby improving the user experience.

[0058] In another embodiment, the method further includes: determining a temperature threshold based on an application currently running in the foreground of the terminal, wherein the power consumption of the application currently running in the foreground of the terminal is positively correlated with the temperature threshold.

[0059] When different applications are running in the foreground of a terminal, the terminal's power consumption and resulting heat generation may vary. There is a positive correlation between power consumption and the temperature threshold. The higher the power consumption of an application, the higher the temperature threshold at which the terminal can be charged using the second current. This compensates for the power consumed by high-power applications and ensures faster charging.

[0060] For example, the power consumption of the game application is greater than that of the chat application, and the temperature threshold corresponding to the game application is greater than the temperature threshold corresponding to the chat application. The temperature threshold can be determined based on the application currently running in the foreground of the terminal.

[0061] The temperature threshold determined based on the application running in the foreground of the terminal should be lower than the maximum temperature allowed by the first position for safety reasons and should have a margin.

[0062] The temperature threshold can also be related to the ambient temperature. All other conditions being equal, the higher the ambient temperature, the sooner the temperature threshold is reached, and the earlier the charging current is limited. Therefore, while not exceeding the maximum allowable temperature, the temperature threshold can increase as the ambient temperature increases. This relatively prolongs the duration of charging with the second current and speeds up charging at higher ambient temperatures. The temperature threshold can be determined based on the application currently running on the terminal and the ambient temperature. For example, a temperature sensor can be used to obtain the ambient temperature.

[0063] For example, the correspondence between the ambient temperature, the application currently running on the terminal, and the temperature threshold can be pre-calibrated. After the application currently running on the terminal and the ambient temperature are determined, the temperature threshold corresponding to the ambient temperature and the application currently running on the terminal is determined from the predetermined correspondence as the determined temperature threshold. Table 1 is a schematic table illustrating the correspondence between the ambient temperature, the application currently running on the terminal, and the temperature threshold.

[0064] Table 1

[0065] Ambient temperature (℃) The application running in the foreground of the terminal Temperature threshold (℃) 25 Short Video 40 27 Short Video 41 25 Browser 39 25 game 45 25 chat 40

[0066] As shown in Table 1, if the ambient temperature is 25°C and the application running in the foreground is a short video application, the temperature threshold is 40°C; if the ambient temperature is 27°C and the application running in the foreground is a short video application, the temperature threshold is 41°C; if the ambient temperature is 25°C and the application running in the foreground is a browser application, the temperature threshold is 39°C; if the ambient temperature is 25°C and the application running in the foreground is a game application, the temperature threshold is 45°C; and if the ambient temperature is 25°C and the application running in the foreground is a chat application, the temperature threshold is 40°C. Table 1 shows a positive correlation between ambient temperature and temperature threshold.

[0067] In this embodiment, the temperature threshold is determined in real time based on the application running in the foreground of the terminal, so that the temperature threshold is adapted to the power consumption of the application running in the foreground of the terminal. When the power consumption of the application running in the foreground of the terminal is large, the higher the terminal temperature allowed to be charged with the second current, thereby reducing the impact of the large power consumption of the currently running application on the charging speed.

[0068] In yet another embodiment, the above method further includes:

[0069] When it is not determined that the terminal is equipped with a protective case, controlling the charging current of the terminal to be a first current;

[0070] If it is determined that the terminal is in a screen-on state while charging and the terminal is equipped with a protective case, the second current is determined according to the current temperature at the first position and the temperature threshold.

[0071] When the terminal starts charging, it can start to determine whether a protective case is installed. Before determining whether a protective case is installed (i.e., it is unknown whether a protective case is installed), the terminal can be controlled to charge with the first current (e.g., 6A) during initial charging in the screen-off state.

[0072] The difference between the current temperature at the first location and the temperature threshold reflects the allowable temperature rise margin at the first location before reaching the safety limit when charging at the second current. The temperature rise of the terminal is related to the magnitude of the charging current. Therefore, if the terminal is in the screen-on state during charging and is equipped with a protective case, the second current can be determined based on the current temperature at the first location and the temperature threshold.

[0073] In this embodiment, the appropriate second current is determined according to the current temperature at the first position and the temperature threshold. The method is simple and has good reliability.

[0074] In yet another embodiment, determining the second current according to the current temperature at the first position and the temperature threshold includes:

[0075] determining a current increase value according to a difference between a temperature threshold and a current temperature at the first position;

[0076] The second current is determined according to the first current and the current increase value.

[0077] The current increase value is the value that needs to be increased to reach the second current based on the current charging current. A correspondence between the difference between the temperature threshold and the current temperature at the first location and the current increase value can be pre-calibrated. After determining the difference between the temperature threshold and the current temperature at the first location, the current increase value corresponding to the difference is found from the predetermined correspondence and used as the determined current increase value.

[0078] When the current charging current is the first charging current, the sum of the first current and the current increase value may be determined as the second current.

[0079] In this embodiment, the current increase value is first determined by using the difference between the temperature threshold and the current temperature at the first position, and then the second current is determined. The method is simple and has good reliability.

[0080] In yet another embodiment, determining the current increase value based on the difference between the temperature threshold and the current temperature at the first position includes: calculating the current increase value according to the following formula:

[0081]

[0082] Wherein, I represents the current increase value; C represents the difference between the temperature threshold and the current temperature at the first position; S represents the heat dissipation coefficient of the terminal; and R represents the charging impedance of the terminal.

[0083] The heat dissipation coefficient of the terminal reflects the heat dissipation capacity of the terminal itself. The heat dissipation coefficient of the terminal is related to the material, internal structure, etc. of the terminal. The heat dissipation coefficient of the terminal can be pre-calibrated by the designer.

[0084] Q=I×I×R (2)

[0085] Wherein, Q represents the heat increase value corresponding to the current increase value I.

[0086] There is also the following formula:

[0087]

[0088] The above formula (1) can be derived from the above formulas (2) and (3).

[0089] After determining the difference between the temperature threshold and the current temperature at the first position, the current increase value may be calculated according to the above formula (1).

[0090] In this embodiment, the current increase value can be quickly calculated according to a simple formula, the method is simple, and the data processing speed is fast.

[0091] In another embodiment, the method further includes: determining whether the terminal is equipped with a protective case based on the temperatures of the first position and the second position on the terminal during the charging process, wherein, if the terminal is equipped with a protective case, the second position is in an area not covered by the protective case.

[0092] The second position is one or more positions that are not in the coverage area of the protective case (such as the screen) when the terminal is equipped with a protective case. The temperature of the second position can be obtained by the NTC sensor. Since the second position is not in the coverage area of the protective case when the terminal is equipped with a protective case, the heat dissipation capacity of the second position before and after the terminal is equipped with the protective case changes little. Under the same ambient temperature and the same charging current, during the terminal charging process, the temperature change difference of the second position when the terminal is equipped with a protective case and when the terminal is not equipped with a protective case is small.

[0093] Since the first position is in the coverage area of the protective shell after the terminal is equipped with the protective shell, the heat dissipation capacity of the first position changes greatly before and after the terminal is equipped with the protective shell. Under the same ambient temperature and the same charging current, during the charging process of the terminal, the temperature change of the first position when the terminal is equipped with a protective shell and when it is not equipped with a protective shell is quite different.

[0094] In this embodiment, whether the terminal is equipped with a protective case can be reliably determined based on the temperatures of the first position and the second position on the terminal during the terminal charging process, and the method is simple.

[0095] In yet another embodiment, the determining whether the terminal is equipped with a protective case based on the temperatures of the first position and the second position on the terminal during the charging process includes:

[0096] determining, based on the temperatures of the first position and the second position at the first moment, and the temperatures of the first position and the second position at the second moment, a first temperature rise characteristic value at the first position and a second temperature rise characteristic value at the second position during a period from the first moment to the second moment, wherein the second moment is separated from the first moment by a predetermined time length;

[0097] Whether the terminal is equipped with a protective case is determined according to the first temperature rise characteristic value and the second temperature rise characteristic value.

[0098] The first moment can be the moment when the terminal starts charging, or a certain period of time after the terminal starts charging. The second moment is a moment during the charging process that is a predetermined time interval from the first moment. For example, the predetermined time interval is 3 minutes. The temperatures of the first and second locations are acquired when the terminal starts charging, and the temperatures of the first and second locations are acquired again 3 minutes later.

[0099] Between the first moment and the second moment, the temperatures at the first location and the second location increase. A first temperature rise characteristic value for the first location can be determined based on the temperatures at the first moment and the second moment. The first temperature rise characteristic value is a characteristic value that reflects the magnitude of the temperature increase at the first location during the terminal charging process. For example, the first temperature rise characteristic value can be determined as the average of the temperatures at the first moment and the second moment, or the first temperature rise characteristic value can be determined as the difference between the temperatures at the first moment and the second moment.

[0100] A second temperature rise characteristic value of the second location can be determined based on the temperature of the second location at the first moment and the second moment. The second temperature rise characteristic value is a characteristic value that can reflect the magnitude of the temperature increase at the second location during the terminal charging process. For example, the second temperature rise characteristic value can be determined as the average of the temperature of the second location at the first moment and the temperature at the second moment, or the second temperature rise characteristic value can be determined as the difference between the temperature of the second location at the first moment and the temperature at the second moment.

[0101] The difference between the first and second temperature rise characteristic values reflects the difference in the temperature increase at the first and second locations during the charging process of the terminal. This difference in temperature increase at the first and second locations during the charging process differs when the terminal is equipped with a protective case and when it is not. Whether the terminal is equipped with a protective case can be determined based on the first and second temperature rise characteristic values.

[0102] In the embodiment, determining the first temperature rise characteristic value and the second temperature rise characteristic value can accurately determine whether the terminal is equipped with a protective case, and the method is simple.

[0103] In yet another embodiment, the determining whether the terminal is equipped with a protective case based on the first temperature rise characteristic value and the second temperature rise characteristic value includes:

[0104] If the difference between the first temperature rise characteristic value and the second temperature rise characteristic value matches the first test data when the terminal is equipped with a protective case, it is determined that the terminal is equipped with a protective case;

[0105] If the difference between the first temperature rise characteristic value and the second temperature rise characteristic value matches the second test data when the terminal is not equipped with a protective case, it is determined that the terminal is not equipped with a protective case.

[0106] Generally, when the terminal is equipped with a protective case, the difference between the first temperature rise characteristic value and the second temperature rise characteristic value from the first moment to the second moment is large; when the terminal is not equipped with a protective case, the difference between the first temperature rise characteristic value and the second temperature rise characteristic value from the first moment to the second moment is small.

[0107] The difference between the first temperature rise characteristic value and the second temperature rise characteristic value during the period from the first moment to the second moment during the charging process when the terminal is equipped with a protective case can be tested in advance through experiments as the first test data, and the difference between the first temperature rise characteristic value and the second temperature rise characteristic value during the period from the first moment to the second moment during the charging process when the terminal is not equipped with a protective case can be tested as the second test data.

[0108] Matching with the first test data may include: an absolute value of a difference with the first test data is smaller than a predetermined threshold, or an absolute value of a difference with the first test data is smaller than an absolute value of a difference with the second test data.

[0109] Matching with the second test data may include: an absolute value of a difference with the second test data is smaller than a predetermined threshold, or an absolute value of a difference with the second test data is smaller than an absolute value of a difference with the first test data.

[0110] The difference between the first and second temperature rise characteristic values is also related to the starting temperature of the terminal charging. The higher the starting temperature, the greater the difference in temperature rise between the first and second locations from the first moment to the second moment, and the greater the difference between the first and second temperature rise characteristic values.

[0111] The temperature of the first and second positions can be detected when the terminal starts charging, and the battery temperature of the terminal at the first moment is the starting temperature of the terminal charging. The ambient temperature when the terminal starts charging can also be used as the starting temperature of the terminal charging.

[0112] For example, the correspondence between the battery temperature at the first moment and the first and second test data can be pre-calibrated through experiments. After obtaining the battery temperature at the first moment, the first and second test data corresponding to the obtained battery temperature at the first moment are found from this correspondence. Table 2 shows a schematic diagram of the correspondence between the battery temperature at the first moment and the first and second test data.

[0113] Table 2

[0114]

[0115]

[0116] As shown in Table 2, when the battery temperature at the first moment is the same, the first test data is greater than the second test data. The battery temperature at the first moment has a positive correlation with the first test data. The battery temperature at the first moment has a positive correlation with the second test data.

[0117] Referring to Table 2, if the battery temperature at the first moment is 20°C, the first test data is 2.4 and the second test data is 1.3. If the determined difference between the first temperature rise characteristic value and the second temperature rise characteristic value is 2.2, and the absolute value of the difference between 2.2 and 2.4 (0.2) is less than the absolute value of the difference between 2.2 and 1.3 (0.9), then the difference between the first temperature rise characteristic value and the second temperature rise characteristic value is determined to match the first test data (2.4) when the terminal is equipped with a protective case.

[0118] In this embodiment, whether the terminal is equipped with a protective case is determined based on the degree of matching between the difference between the first temperature rise characteristic value and the second temperature rise characteristic value and the test data of the terminal with and without the protective case obtained in advance. This can accurately and quickly determine whether the terminal is equipped with a protective case.

[0119] In yet another embodiment, the method further includes: if the temperature at the first location reaches a temperature threshold, controlling the terminal to charge with a first current.

[0120] When the terminal is equipped with a protective case and is in the screen-on state and is charged with the second current, when the temperature of the first position in the area covered by the protective case reaches the temperature threshold, it is considered that the temperature of the terminal is already high. If the terminal continues to be controlled to charge with the second current, it is easy to cause the terminal to overheat and there is a risk of damage. Therefore, the terminal is controlled to charge with the smaller first current.

[0121] In this embodiment, when the temperature at the first position reaches the temperature threshold, the terminal is controlled to be charged with the first current, thereby reducing the risk of terminal damage and increasing the service life of the terminal.

[0122] Figure 2 The figure is a flow chart of a terminal charging control method according to another exemplary embodiment. Figure 2 The steps in the embodiment are a combination of the steps in the above multiple embodiments, and specifically include the following steps.

[0123] 1. During the charging process of the terminal, a first temperature rise characteristic value of the first position and a second temperature rise characteristic value of the second position are determined during the period from the first moment to the second moment based on the temperatures of the first position and the second position at the first moment and the temperatures of the first position and the second position at the second moment.

[0124] 2. If the difference between the first temperature rise characteristic value and the second temperature rise characteristic value matches the first test data when the terminal is equipped with a protective case, it is determined that the terminal is equipped with a protective case.

[0125] 3. If the difference between the first temperature rise characteristic value and the second temperature rise characteristic value matches the second test data when the terminal is not equipped with a protective case, it is determined that the terminal is not equipped with a protective case.

[0126] 4. When it is not determined that the terminal is equipped with a protective case, controlling the charging current of the terminal to be a first current.

[0136] The first determining module is configured to determine a temperature threshold according to an application currently running in the foreground of the terminal, wherein the power consumption of the application currently running in the foreground of the terminal is positively correlated with the temperature threshold.

[0137] Optionally, the terminal control device 600 further includes a second control module and a second determination module.

[0138] The second control module is configured to control the charging current of the terminal to be the first current when it is not determined that the terminal is equipped with a protective case.

[0139] The second determination module is configured to determine the second current according to the current temperature at the first position and the temperature threshold if it is determined that the terminal is in a screen-on state while charging and the terminal is equipped with a protective case.

[0140] Optionally, the second determining module includes a first determining submodule and a second determining submodule.

[0145]

[0146] Wherein, I represents the current increase value; C represents the difference between the temperature threshold and the current temperature at the first position; S represents the heat dissipation coefficient of the terminal; and R represents the charging impedance of the terminal.

[0147] Optionally, the terminal control device 600 further includes a judgment module.

[0148] The judgment module is configured to judge whether the terminal is equipped with a protective case based on the temperatures of a first position and a second position on the terminal during the terminal charging process, wherein, when the terminal is equipped with a protective case, the second position is in an area not covered by the protective case.

[0149] Optionally, the judgment module includes a third determination submodule and a judgment submodule.

[0150] The third determination submodule is configured to determine a first temperature rise characteristic value of the first position and a second temperature rise characteristic value of the second position during a period from the first moment to the second moment based on the temperatures of the first position and the second position at the first moment, and the temperatures of the first position and the second position at the second moment, wherein the second moment is separated from the first moment by a predetermined time length.

[0157] Regarding the apparatus in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0158] Through the above technical solution, compared with the screen-off state, when the terminal is in the screen-on state and equipped with a protective case, the charging current of the terminal is larger, and the terminal temperature limit value that limits the charging current is higher. This solution adopts different charging strategies for different scenarios in which the terminal is located. When the terminal equipped with a protective case is charging and running at the same time, a larger charging current and a higher terminal temperature limit value are adopted to avoid limiting the charging current too early. In this way, the charging strategy of the terminal is flexibly switched according to the charging scenario. On the one hand, it meets the user's demand for fast charging of the terminal when using the terminal. On the other hand, it avoids the user's failure to perceive that the terminal has reached a high temperature due to the heat insulation effect of the protective case, and mistakenly believes that the charging has not slowed down, thereby improving the user experience.
