[0033] In order to solve the problem of heating of terminal equipment during charging, one solution provided by the existing related technology is to use different charging voltages and currents at different stages according to a pre-set charging curve, such as Figure 1 As shown, Figure 1 A schematic diagram of a charging method provided by the prior art. Figure 1 In the scheme shown, a temperature control threshold is set during the entire charging process. When the temperature rises to near the threshold, the current is limited to reduce the temperature rise.

[0034] but, Figure 1 The scheme shown does not take environmental factors into consideration and charges according to the established charging strategy: the temperature rises rapidly during the high-current charging stage, which poses a safety hazard in a closed flammable environment, and the temperature control and current limiting will be frequently triggered, affecting the charging speed. The above scheme also does not take into account the charging habits of users. Each user has different charging habits and needs. Some users use fragmented time to perform multiple short charges. In this case, the demand of such users is to charge as much power as possible in a short period of time. Some users use their rest time at night to keep the charger plugged in for a long time. In this case, the demand of such users is charging safety and extending battery life.

[0035] Based on the above problems, an embodiment of the present application provides a charging method for a terminal device, which is used in a scenario where the user is charging. The terminal device can sense the surrounding environment through its own sensors, learn the user's usage habits through machine learning, and intelligently set charging parameters so that the terminal device can be intelligently charged in a way that provides the best user experience. This allows the charging strategy to be customized based on the environmental information of the terminal device's current environment and the user's charging habits, thereby ensuring the charging effect and preventing the user from feeling obvious heat during the charging process, thereby improving the user's experience.

[0091] For ease of understanding, the following embodiments of the present application will use a terminal device with the Figure 2 shown structure as an example, and in combination with the accompanying drawings and application scenarios, specifically elaborate on the charging method of the terminal device provided in the embodiments of the present application.

[0092] Figure 3 The flowchart of the charging method of the terminal device provided in an embodiment of the present application is as Figure 3 shown. The charging method of the above terminal device may include:

[0093] Step 301, the terminal device 100 obtains the environmental information of the environment where the terminal device 100 is currently located, and obtains the charging habits of the user using the terminal device 100. Among them, the above environmental information may include the temperature of the terminal device 100 itself and the heat dissipation conditions of the environment where the terminal device 100 is currently located.

[0094] Among them, the above environmental information may include the temperature of the terminal device 100 itself, the motion state information of the terminal device 100, the environmental image of the environment where the terminal device 100 is currently located, and the information on whether there are objects approaching near the terminal device 100.

[0095] Specifically, when implemented, refer to Figure 4 , Figure 4Schematic diagram of the implementation of the charging method for the terminal device provided by an embodiment of the present application. The processor 110 in the terminal device 100 can collect the temperature of the terminal device 100 itself through the temperature sensor 180J, collect the motion state information of the terminal device 100 through the acceleration sensor 180E, collect the environmental image of the current environment where the terminal device 100 is located through the camera 193, and collect the environmental change information of the environment where the terminal device 100 is located through the proximity light sensor 180G, such as information on whether there is an object approaching near the terminal device 100; in addition, the processor 110 can also obtain the charging habits of the user through machine learning.

[0096] Step 302, when the temperature of the terminal device 100 itself is less than or equal to a predetermined temperature threshold, and the heat dissipation condition of the current environment where the terminal device 100 is located meets the predetermined heat dissipation condition, determine the charging strategy according to the charging habits of the user.

[0097] Among them, the above-mentioned predetermined temperature threshold can be set by itself according to system performance and / or implementation requirements, etc. in specific implementation. This embodiment does not limit the size of the above-mentioned predetermined temperature threshold. For example, the above-mentioned predetermined temperature threshold can be 50 degrees.

[0098] The above-mentioned predetermined heat dissipation condition can also be set by itself in specific implementation. For example, when the terminal device 100 is placed on a sofa or a bed, it can be determined that the heat dissipation condition is poor and does not meet the predetermined heat dissipation condition; while when the terminal device 100 is placed on a table, it can be determined that the heat dissipation condition is good and meets the predetermined heat dissipation condition.

[0099] Specifically, referring to Figure 4 , after the processor 110 obtains the environmental information of the current environment where the terminal device 100 is located and obtains the charging habits of the user using the terminal device 100, it can formulate a charging strategy for the terminal device 100 according to the above environmental information and charging habits.

[0100] In this embodiment, in this embodiment, the temperature sensor 180J measures the temperature of the terminal device 100 itself, and then transmits the measured temperature of the terminal device 100 itself to the processor 110, and the processor 110 determines whether the temperature of the terminal device 100 itself is greater than the predetermined temperature threshold.

[0101] When the temperature of the terminal device 100 itself is less than or equal to the predetermined temperature threshold, and the heat dissipation condition around the terminal device 100 is good and meets the predetermined heat dissipation condition, the processor 110 formulates a charging strategy according to the charging habits of the user.

[0102] Step 303, charge the terminal device 100 according to the above charging strategy.

[0103] Specifically, after the processor 110 formulates the charging strategy, it can transmit the above charging strategy to the charging management module 140, and the charging management module 140 charges the battery 142 according to the above charging strategy.

[0104] In the charging method of the above terminal device, after the terminal device 100 obtains the environmental information of the environment where the terminal device 100 is currently located and the charging habits of the user using the terminal device 100, when the temperature of the terminal device 100 itself is less than or equal to a predetermined temperature threshold and the heat dissipation condition of the environment where the terminal device 100 is currently located meets the predetermined heat dissipation condition, a charging strategy is determined according to the charging habits of the user. Then, according to the above charging strategy, the terminal device 100 is charged, so that a charging strategy can be customized according to the environmental information of the environment where the terminal device is currently located and the charging habits of the user, which can not only ensure the charging effect, but also prevent the user from feeling obvious heat during the charging process, thereby improving the user experience.

[0105] Figure 5 The flowchart of the charging method of the terminal device provided by another embodiment of the present application is as Figure 5 shown. In the embodiment Figure 3 shown, step 302 may be:

[0106] Step 501, when the temperature of the terminal device 100 itself is less than or equal to a predetermined temperature threshold and the heat dissipation condition of the environment where the terminal device 100 is currently located meets the predetermined heat dissipation condition, if the charging habit of the above user is that in the current time period, the charging times of the terminal device 100 are less than the first predetermined number of times and the charging duration of the terminal device 100 is greater than or equal to the first predetermined duration, then determine the charging strategy as a long-time safe charging strategy; or, if the charging habit of the above user is that in the current time period, the charging times of the terminal device 100 are greater than or equal to the second predetermined number of times and the charging duration of the terminal device 100 is less than the second predetermined duration, then when no human body is detected within a predetermined distance range, determine the above charging strategy as a short-time fast charging strategy; and / or, after a human body is detected within the above predetermined distance range, end the charging process of the terminal device 100.

[0107] Among them, the above predetermined distance range includes a range where the distance from the terminal device 100 is less than or equal to a predetermined distance; the size of the above predetermined distance can be set by itself according to system performance and / or implementation requirements, etc. in specific implementation. This embodiment does not limit the size of the above predetermined distance. For example, the above predetermined distance can be 30 centimeters.

[0108] The above first predetermined number of times is less than or equal to the second predetermined number of times, and the first predetermined duration is greater than or equal to the second predetermined duration. Similarly, the magnitudes of the first predetermined number of times, the second predetermined number of times, the first predetermined duration, and the second predetermined duration can be set by themselves in specific implementations, and this embodiment does not limit this.

[0109] In specific implementation, the distance sensor 180F can detect whether there is a human body within a predetermined distance range. Then, the processor 110 can, according to the information detected by the distance sensor 180F, know whether a user is approaching the terminal device 100.

[0110] In this embodiment, when the temperature of the terminal device 100 itself is less than or equal to a predetermined temperature threshold, and the heat dissipation conditions around the terminal device 100 are good and meet the predetermined heat dissipation conditions, if the user is accustomed to charging for a long time during the current time period, the processor 110 determines the charging strategy as a long-time safe charging strategy. The long-time safe charging strategy can make full use of the complete charging duration and be fully charged before the user ends charging, which can avoid repeated charging stops and restarts.

[0111] If the user is accustomed to charging multiple times for short durations using fragmented time during the current time period, when the distance sensor 180F does not detect a human body within the predetermined distance range, the processor 110 determines the above charging strategy as a short-time fast charging strategy. The short-time fast charging strategy can make full use of the fast charging ability and charge with the maximum charging current. In this state, the temperature rise may exceed the limited temperature threshold in a short time, which is a charging speed optimization strategy. When charging using the short-time fast charging strategy, if the distance sensor 180F detects a human body within the above predetermined distance range, the processor 110 notifies the charging management module 140 to end the charging process of the battery 142, so that the short-time charging ends in advance and the temperature of the terminal device 100 itself is reduced.

[0112] In addition, when the user is accustomed to charging multiple times for short durations using fragmented time, if the distance sensor 180F detects a human body within the predetermined distance range, the charging process of the terminal device 100 can be directly ended.

[0113] Figure 6 For the flowchart of the charging method of the terminal device provided in another embodiment of the present application, as Figure 6 shown, in the embodiment shown in the present application Figure 3 after step 301, it may further include:

[0114] Step 601, when the temperature of the terminal device 100 itself is greater than the predetermined temperature threshold, determine the above charging strategy as a current-limiting charging strategy.

[0115] In this way, step 303 can be:

[0116] Step 602: Enter the thermal current limiting state according to the above current limiting charging strategy to reduce the charging current of the terminal device 100.

[0117] In this embodiment, the temperature sensor 180J measures the temperature of the terminal device 100 itself, and then transmits the measured temperature of the terminal device 100 itself to the processor 110. The processor 110 determines whether the temperature of the terminal device 100 itself is greater than a predetermined temperature threshold. When the temperature of the terminal device 100 itself is greater than the predetermined temperature threshold, the processor 110 determines the charging strategy as the current limiting charging strategy and transmits the current limiting charging strategy to the charging management module 140. At this time, the charging management module 140 immediately executes the above current limiting charging strategy, enters the thermal current limiting state, and reduces the charging current of the battery 142, so that the temperature of the terminal device 100 can be quickly reduced. Moreover, in this charging state, the processor 110 monitors the temperature sensor 180J regularly or periodically. After the temperature of the terminal device 100 itself drops to less than or equal to the predetermined temperature threshold, the processor 110 can notify the charging management module 140 to increase the charging current.

[0118] Figure 7 The flowchart of the charging method of the terminal device provided for another embodiment of the present application is as Figure 7 shown. In the embodiment shown in the present application Figure 3 after step 301, it may further include:

[0119] Step 701: When the temperature of the terminal device 100 itself is less than or equal to the predetermined temperature threshold and the heat dissipation condition of the environment where the terminal device 100 is currently located does not meet the predetermined heat dissipation condition, determine the charging strategy as the temperature-priority safe charging strategy.

[0120] In this embodiment, when the temperature of the terminal device 100 itself is less than or equal to the predetermined temperature threshold and the heat dissipation condition around the terminal device 100 is poor and does not meet the predetermined heat dissipation condition, the processor 110 can determine to use the temperature-priority safe charging strategy. When using the temperature-priority safe charging strategy, the charging management module 140 can charge the battery 142 with a smaller charging current to control the rising speed of the temperature. Moreover, in this charging state, the processor 110 monitors the temperature sensor 180J regularly or periodically. After the temperature of the terminal device 100 itself rises to greater than the predetermined temperature threshold, the processor 110 can notify the charging management module 140 to charge using the current limiting charging strategy.

[0121] The present application Figures 3 to 7The method provided by the illustrated embodiment can customize the optimal charging strategy according to the environmental information of the current environment of the terminal device 100 and the user's charging habits, which not only ensures the charging effect but also makes the user feel no obvious heat during the charging process, improving the user experience.

[0122] Figure 8 Schematic diagram of the charging method of the terminal device provided by another embodiment of the present application. As Figure 8 shown, after determining the charging strategy according to the method provided by the embodiment of the present application Figures 3 to 7 shown, if the charging strategy is a temperature-priority safe charging strategy, after the charging management module 140 charges the battery 142 according to the temperature-priority safe charging strategy, the processor 110 can obtain the environmental information of the current environment where the terminal device 100 is located. If the temperature of the terminal device 100 itself is less than or equal to the predetermined temperature threshold and the heat dissipation condition of the current environment where the terminal device 100 is located meets the predetermined heat dissipation condition, this indicates that the terminal device 100 has been moved to an environment with good heat dissipation. At this time, the processor 110 can switch the charging strategy to a long-time safe charging strategy or a short-time fast charging strategy according to the user's charging habits, as Figure 8 shown by arrow 81 in

[0123] In addition, after determining the charging strategy according to the method provided by the embodiment of the present application Figures 3 to 7 shown, if the charging strategy is a long-time safe charging strategy or a short-time fast charging strategy, after the charging management module 140 charges the battery 142 according to the long-time safe charging strategy or the short-time fast charging strategy, the processor 110 can obtain the environmental information of the current environment where the terminal device 100 is located; if the temperature of the terminal device 100 itself is less than or equal to the predetermined temperature threshold and the heat dissipation condition of the current environment where the terminal device 100 is located does not meet the predetermined heat dissipation condition, for example, during the charging process, the terminal device 100 falls into an area with poor heat dissipation (such as a sofa gap), then the processor 110 can determine to switch the charging strategy to a temperature-priority safe charging strategy, as Figure 8 shown by arrow 82 in

[0124] After the battery 142 is fully charged using the long-time safe charging strategy or the short-time fast charging strategy, the charging management module 140 can end the charging; or, when charging using the short-time fast charging strategy, if the proximity sensor 180F detects that a user is approaching the terminal device 100, then the processor 110 can notify the charging management module 140 to end the charging, as Figure 8 shown by arrow 83 in

[0125] In addition, if the user's charging habit changes, the processor 110 can switch the charging strategy from the long-term safe charging strategy to the short-term fast charging strategy, or switch the charging strategy from the short-term fast charging strategy to the long-term safe charging strategy according to the user's charging habit, as Figure 8 shown by arrow 84 in

[0126] Furthermore, it should be noted that during the charging process, if the temperature of the terminal device 100 itself rises abnormally and is greater than a predetermined temperature threshold, the processor 110 determines to switch the charging strategy to a current-limiting charging strategy. After the temperature of the terminal device 100 itself drops to less than or equal to the predetermined temperature threshold, the original charging strategy used is restored. As Figure 8 shown, if the temperature of the terminal device 100 rises abnormally and is greater than a predetermined temperature threshold during the process of the charging management module 140 charging the battery 142 using the temperature-priority safe charging strategy, the processor 110 determines to switch the charging strategy to a current-limiting charging strategy to quickly reduce the temperature of the terminal device 100. After the temperature of the terminal device 100 itself drops to less than or equal to the predetermined temperature threshold, the temperature-priority safe charging strategy is restored, as Figure 8 shown by arrow 85 in

[0127] Similarly, if the temperature of the terminal device 100 rises abnormally and is greater than a predetermined temperature threshold during the process of the charging management module 140 charging the battery 142 using the long-term safe charging strategy, the processor 110 determines to switch the charging strategy to a current-limiting charging strategy to quickly reduce the temperature of the terminal device 100. After the temperature of the terminal device 100 itself drops to less than or equal to the predetermined temperature threshold, the long-term safe charging strategy is restored, as Figure 8 shown by arrow 86 in

[0128] If the temperature of the terminal device 100 rises abnormally and is greater than a predetermined temperature threshold during the process of the charging management module 140 charging the battery 142 using the short-term fast charging strategy, the processor 110 determines to switch the charging strategy to a current-limiting charging strategy to quickly reduce the temperature of the terminal device 100. After the temperature of the terminal device 100 itself drops to less than or equal to the predetermined temperature threshold, the short-term fast charging strategy is restored, as Figure 8 shown by arrow 87 in

[0129] This embodiment can charge the battery 142 using different charging strategies according to changes in the environment and human factors.
