[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] In the related art, in order to control the temperature of the entire electronic device when it is charging, the charging current is usually gradually reduced when the temperature of the entire electronic device rises to reduce the charging power. At this time, there will be not only serious heating but also slow charging speed. In addition, when the electronic device is in the same application scenario for a long time, after reducing the temperature of the entire device by reducing the charging current, the temperature of the entire device will gradually tend to a stable value, and the charging current will also stabilize at a reduced charging current value and will no longer change. At this time, the charging power of the electronic device is stabilized at a lower power value, and the charging power will no longer increase, so the charging speed will not increase either. The problem of slow charging speed still exists, affecting the user's charging experience.

[0047] In an exemplary embodiment of the present disclosure, in order to overcome the problem of serious heating and slow charging speed of electronic devices in related technologies, a charging method is provided, including: when the surface temperature of the electronic device is less than a first charging temperature threshold, charging with multiple different first charging parameters at different times; when the surface temperature of the electronic device is greater than the first charging temperature threshold and less than a second charging temperature threshold, charging with multiple different second charging parameters at different times; wherein the second charging temperature threshold is greater than the first charging temperature threshold, the first charging parameter is greater than a first set value, the second charging parameter is less than a second set value, and the second set value is less than the first set value. The charging method oscillates and cycles charging between a larger charging parameter and a smaller charging parameter, and can improve the charging speed while controlling the surface temperature of the electronic device below the highest surface temperature acceptable to the user, thereby improving the user's charging experience.

[0048] In an exemplary embodiment of the present disclosure, a charging method is provided. Figure 1 is a flow chart of a charging method according to an exemplary embodiment. Figure 1 As shown, the following steps are included:

[0049] Step S101, when the surface temperature of the electronic device is less than a first charging temperature threshold, charging is performed at different times using a plurality of different first charging parameters;

[0050] Step S102, when the surface temperature of the electronic device is greater than a first charging temperature threshold, charging is performed at different times using a plurality of different second charging parameters;

[0051] The first charging parameter is greater than a first set value, the second charging parameter is less than a second set value, and the second set value is less than the first set value.

[0052] The method in the exemplary embodiment of the present disclosure is applied to electronic devices, including smart phones, tablet computers, smart wearable devices, smart home devices and other electronic devices. The charging method in the embodiment of the present disclosure can be used as the default charging method of the electronic device, or as an optional charging method of the electronic device. In the charging-related settings, options related to the charging method in this embodiment are set, and the user is prompted to turn on the charging method to optimize the heating phenomenon during charging. When the user turns on the charging method through the relevant options, the charging method in this embodiment is used for charging.

[0053] The surface temperature of the electronic device is the shell temperature of the electronic device. A thermistor can be set on the main board of the electronic device to obtain the resistance change of the thermistor during charging. The temperature change around the thermistor, that is, the change of the surface temperature of the electronic device, can be obtained by using a fitting algorithm.

[0054] The first charging temperature threshold represents the degree before the highest surface temperature that the user can accept when the electronic device is charging under the current ambient temperature. In one example, when the electronic device is charging in the screen-off standby state, in an indoor environment of 25°C, the surface temperature of the electronic device that the user can accept is 39°C or below; in an outdoor summer environment of 35°C, the surface temperature of the electronic device that the user can accept is 42°C or below. Then, when the electronic device is charging in the screen-off standby state, the first charging temperature threshold in an indoor environment of 25°C is the degree before 39°C, that is, 38°C, and the first charging temperature threshold in an outdoor summer environment of 35°C is the degree before 42°C, 41°C.

[0055] In some possible implementations, when the charging scenarios of the electronic device are different, the first charging temperature threshold may be different or the same, and may be determined according to actual needs. For example, when the first charging temperature threshold corresponding to a charging scenario with higher power consumption is lower than the first charging temperature threshold corresponding to a charging scenario with lower power consumption, the first charging temperature threshold when charging in a gaming scenario or a video playback scenario is lower than the first charging temperature threshold when charging in the screen-off standby state.

[0056] The charging parameter may be a charging voltage, a charging current, or a charging power. In this embodiment, the charging parameter takes the charging current as an example. The charging parameter includes a first charging parameter and a second charging parameter. The first charging parameter and the second charging parameter have different values. When the surface temperature is low, charging is performed with a higher charging current to increase the charging speed. When the surface temperature is high, charging is performed with a lower charging current to avoid an increase in the surface temperature. Therefore, the first charging parameter is greater than the second charging parameter.

[0057] When the ambient temperature is the ambient temperature corresponding to the first charging temperature threshold, when the surface temperature of the electronic device is less than the first charging temperature threshold, charging is performed at different times with multiple different first charging parameters, and the corresponding first charging parameter can be determined according to the change in the surface temperature of the electronic device. When the surface temperature rises, the first charging parameter decreases. Since the surface temperature of the electronic device is relatively low, in order to ensure the charging speed, it is charged with a larger charging current, so the first charging parameter is greater than the first set value. Among them, the first set value is an empirical value, and in order to make the surface temperature of the electronic device continue to rise, it can be determined according to the maximum charging current that the electronic device can withstand. For example, the first set value is greater than 50% of the maximum charging current. When the maximum charging current that the electronic device can withstand is 12A, the first set value can be 6.5A. If the first charging parameter is greater than the first set value, the surface temperature will continue to rise.

[0058] Since the first charging parameter is relatively large, the surface temperature of the electronic device will gradually increase when charging with the first charging parameter. When the surface temperature of the electronic device increases to be greater than the first charging temperature threshold, it is charged with the second charging parameter.

[0059] When the surface temperature of the electronic device is greater than the first charging temperature threshold, it is charged with multiple different second charging parameters at different times. The corresponding second charging parameter can be determined according to the change of the surface temperature of the electronic device. When the surface temperature increases, the second charging parameter decreases. Since the surface temperature of the electronic device is relatively high, in order to further increase the surface temperature and quickly reduce the surface temperature at the same time, charging is performed with a smaller charging current, so the second charging parameter is less than the second set value. Among them, the second set value is an empirical value, which is a value that reduces the surface temperature of the electronic device. It can be determined according to the maximum charging current that the electronic device can withstand. For example, the first set value is less than 50% of the maximum charging current. When the maximum charging current that the electronic device can withstand is 12A, the second set value can be 5.5A. The second charging parameter is less than the second set value, which will cause the surface temperature to drop. In order to ensure that the above effect can be achieved, the second set value is less than the first set value.

[0060] Since the second charging parameter is smaller, the surface temperature of the electronic device can be reduced when charging with the second charging parameter. When the surface temperature of the electronic device is reduced to less than the first charging temperature threshold, it is charged again with the first charging parameter.

[0061] In an exemplary embodiment of the present disclosure, when the surface temperature of the electronic device is lower than a first charging temperature threshold, charging is performed with a larger charging parameter to ensure the charging speed. When the surface temperature of the electronic device is higher than the first charging temperature threshold, charging is performed with a smaller charging parameter to quickly reduce the surface temperature of the electronic device so that the charging parameter can be adjusted to the first charging parameter again, and charging is performed with a larger charging parameter again to ensure the charging speed. Thus, oscillating cyclic charging between a larger charging parameter and a smaller charging parameter can increase the charging speed while controlling the surface temperature of the electronic device below the maximum surface temperature acceptable to the user, thereby improving the user's charging experience.

[0062] In some possible implementations, the electronic device includes a plurality of charging gears, each charging gear includes a trigger temperature interval, a reset temperature interval, and a charging parameter corresponding to the trigger temperature interval, as the temperature of the trigger temperature interval and the reset temperature interval increases, the charging parameter decreases, the charging parameter includes a first charging parameter and a second charging parameter, and the charging method further includes:

[0063] When the trigger temperature interval is less than the first charging temperature threshold, the charging parameter corresponding to the trigger temperature interval is the first charging parameter;

[0064] When the trigger temperature interval is greater than the first charging temperature threshold, the charging parameter corresponding to the trigger temperature interval is the second charging parameter.

[0065] The trigger temperature interval and the reset temperature interval can be a temperature value, and when the surface temperature reaches the temperature value, the corresponding operation is performed; or it can be a temperature range, and when the surface temperature is within the temperature range, the corresponding operation is performed. The trigger temperature interval means that when the surface temperature of the electronic device reaches the trigger temperature interval, it is charged with the charging parameters corresponding to the interval; the reset temperature interval means that when the surface temperature of the electronic device reaches the reset temperature interval, it is reset to the charging position when the trigger temperature interval is the reset temperature interval, and charged with the charging parameters corresponding to the reset charging position.

[0066] In one example, when the trigger temperature interval is a temperature value and the charging parameter is a charging current, the maximum surface temperature acceptable to the user is 39°C, the first charging temperature threshold is 38°C, the first setting value is 6A, and the second setting value is 5.5A. Table 1 is a corresponding relationship table of charging gears, trigger temperatures, reset temperatures, and charging currents according to an exemplary embodiment. As shown in Table 1, as the temperature of the trigger temperature interval and the reset temperature interval increases, the charging current decreases. The charging currents corresponding to charging gears 1, 2, and 3 are the first charging parameters, and the charging currents corresponding to the remaining charging gears are the second charging parameters. When charging in this way, the charging current oscillates between 6.6A and 5A. On the premise that the surface temperature of the electronic device is controlled below the maximum surface temperature of 39°C acceptable to the user, it can also be charged with a larger charging current of 6.6A, thereby improving the charging speed.

[0069] In some possible implementations, when charging is performed at different times with a plurality of different charging parameters, it includes:

[0070] When the surface temperature rises, the target trigger temperature interval to which the surface temperature belongs is determined, the gear corresponding to the target trigger temperature interval is determined as the target charging gear, and charging is performed with the charging parameters of the target charging gear;

[0071] When the surface temperature drops, when the surface temperature is in the return temperature interval corresponding to the target trigger temperature interval, charging is performed with the charging parameters of the previous charging gear of the target charging gear, wherein the charging parameters of the previous charging gear of the target charging gear are greater than the charging parameters of the target charging gear.

[0072] When the surface temperature of the electronic device gradually rises, the charging parameters are determined by the trigger temperature interval, the target trigger temperature interval to which the surface temperature belongs is determined, the gear corresponding to the target trigger temperature interval is determined as the target charging gear, and charging is performed with the charging parameters of the target charging gear. For example, as shown in Table 1, when the surface temperature rises to 38.5°C, the target charging gear is gear 4, and charging is performed with the charging parameter 5A. When the surface temperature of the electronic device gradually decreases, the charging parameters are determined by the reset temperature interval. When charging is performed with the charging parameters corresponding to the target trigger temperature interval, whether the surface temperature rises or decreases depends on the hardware situation of the electronic device, which is different for different models. If the surface temperature continues to rise, the trigger temperature interval to which it belongs is continued to be determined; if the surface temperature decreases, when the surface temperature drops to the reset temperature interval corresponding to the target trigger temperature interval, charging is performed with the charging parameters of the previous charging gear of the target charging gear. For example, as shown in Table 1, when the electronic device is charged with a charging parameter of 5A, it is determined that the surface temperature at this time will drop. Then, when it drops to the return temperature range, it is charged with the charging parameters of the previous charging gear of the target charging gear, that is, it is charged with a charging current of 6.6A corresponding to gear 3.

[0073] Under different surface temperature changes, charging parameters are determined according to the trigger temperature range and the return temperature range respectively, which can make the charging method more adaptable and suitable for more models.

[0074] In some possible implementations, when the trigger temperature interval is greater than the first charging temperature and less than the second charging temperature, the difference between the trigger temperature intervals of two adjacent charging gears is less than a difference threshold, wherein the first charging temperature is less than the first charging temperature threshold, and the second charging temperature is greater than the first charging temperature threshold.

[0075] The first charging temperature and the second charging temperature are the charging temperatures before and after the first charging temperature threshold, and the difference threshold is a smaller value, such as 0.8°C or 1°C. When the difference between the triggering temperature intervals of two adjacent charging gears before and after the first charging temperature threshold is very small, the surface temperature can change rapidly when the charging parameters change. When the charging gears are switched cyclically, the charging time for charging with larger charging parameters will be longer, thereby achieving the technical effect of improving the charging speed. For example, as shown in Table 1, the difference between the triggering temperature intervals of two adjacent charging gears before and after the first charging temperature threshold of 38°C is only 0.7°C. When the charging current is 5A, the surface temperature can be quickly reduced to 37.8°C, so that charging can continue at 6.6A, thereby achieving the effect of improving the charging speed.

[0076] In some possible implementations, the charging scenarios of the electronic device are different, and the charging parameters in the same charging gear are different.

[0077] The charging scenario of an electronic device refers to the power consumption state of the electronic device when charging. When the electronic device is in a charging scenario with higher power consumption, such as a gaming scenario or a video playback scenario, in order to avoid the power consumption itself causing the electronic device to heat up more seriously, the charging parameters of the same charging gear are reduced compared to the electronic device being in a charging scenario with lower power consumption, such as a screen-off standby scenario.

[0078] In an exemplary embodiment of the present disclosure, a charging method is provided. Figure 2 is a flow chart of a charging method according to an exemplary embodiment. Figure 2 As shown, the following steps are included:

[0079] Step S201, when the surface temperature of the electronic device is less than a first charging temperature threshold, charging is performed at different times using a plurality of different first charging parameters;

[0080] Step S202, when the surface temperature of the electronic device is greater than the first charging temperature threshold and less than the second charging temperature threshold, charging is performed at different times using a plurality of different second charging parameters;

[0081] Step S203, when the surface temperature of the electronic device is greater than the second charging temperature threshold, charging is performed at different times using a plurality of different third charging parameters;

[0082] Among them, the second charging temperature threshold is greater than the first charging temperature threshold, the first charging parameter is greater than the first set value, the second charging parameter is less than the second set value and greater than the third set value, the third charging parameter is less than the third set value, the second set value is less than the first set value, and the third set value is less than the second set value.

[0083] The charging temperature threshold includes a first charging temperature threshold and a second charging temperature threshold. The charging temperature threshold indicates the maximum surface temperature that a user can accept when the electronic device is charging. Under different ambient temperatures, the maximum surface temperature that a user can accept when charging is also different. When the charging ambient temperature is low, the maximum surface temperature that a user can accept will also be relatively low. At this time, the charging temperature threshold is the first charging temperature threshold, and the value is relatively low; when the charging ambient temperature is high, the maximum surface temperature that a user can accept will also be relatively high. At this time, the charging temperature threshold is the second charging temperature threshold, and the value is relatively high. Therefore, the first charging temperature threshold and the second charging temperature threshold are determined according to the ambient temperature of the location where the electronic device is charging, and the first charging temperature threshold is less than the second charging temperature threshold.

[0084] The charging parameters also include a third charging parameter, which has a different value from the first charging parameter and the second charging parameter. When the surface temperature is low, charging is performed with a higher charging current to increase the charging speed; when the surface temperature is high, charging is performed with a lower charging current to avoid an increase in the surface temperature. Therefore, the third charging parameter is smaller than the second charging parameter.

[0085] When the ambient temperature is the ambient temperature corresponding to the first charging temperature threshold, the specific charging method is referred to the above embodiment, which will not be repeated here; when the ambient temperature rises to the ambient temperature corresponding to the second charging temperature threshold, when the surface temperature of the electronic device is greater than the first charging temperature threshold and less than the second charging temperature threshold, the specific charging method is referred to the above embodiment. Since the surface temperature of the electronic device is relatively low, in order to ensure the charging speed, it is charged with a larger charging current, so the second charging parameter is less than the second set value and greater than the third set value. Since the second charging parameter is relatively large, when charging with the second charging parameter, the surface temperature of the electronic device will gradually increase. When the surface temperature of the electronic device increases to greater than the second charging temperature threshold, it is charged with the third charging parameter.

[0086] When the surface temperature of the electronic device is greater than the second charging temperature threshold, the device is charged at different times with multiple different third charging parameters, and the corresponding third charging parameter can be determined according to the change in the surface temperature of the electronic device. When the surface temperature increases, the third charging parameter decreases. Since the surface temperature of the electronic device is relatively high, in order to further increase the surface temperature and quickly reduce the surface temperature at the same time, the device is charged with a smaller charging current, so the third charging parameter is less than the third set value. Since the third charging parameter is relatively small, the surface temperature of the electronic device can be reduced when the device is charged with the third charging parameter. When the surface temperature of the electronic device is reduced to less than the second charging temperature threshold, the device is charged again with the second charging parameter.

[0087] The third setting value is an empirical value and can be determined according to the second charging parameter. For example, the second setting value is 5.5A. When the second charging parameter is 5A, the third setting value is less than the second charging parameter, and the third setting value can be 4.5A. When the ambient temperature is high, for a better cooling effect, the third charging parameter can be less than 70% of the third setting value, for example, the third charging parameter is 2.6A. In order to ensure that the above effect can be achieved, the third setting value is less than the second setting value.

[0088] In an exemplary embodiment of the present disclosure, when the ambient temperature is low, charging is oscillated and cycled between a larger charging parameter and a smaller charging parameter, which can improve the charging speed while controlling the surface temperature of the electronic device at or below a first charging temperature threshold. When the ambient temperature rises, charging is oscillated and cycled between a smaller charging parameter and an even smaller charging parameter, which can improve the charging speed while controlling the surface temperature of the electronic device at or below a second charging temperature threshold. The charging strategy is adjusted according to the ambient temperature to meet charging needs at different ambient temperatures and improve the user's charging experience.

[0089] In some possible implementations, the electronic device includes a plurality of charging gears, each charging gear includes a trigger temperature interval, a reset temperature interval, and a charging parameter corresponding to the trigger temperature interval, as the temperature of the trigger temperature interval and the reset temperature interval increases, the charging parameter decreases, the charging parameter includes a first charging parameter, a second charging parameter, and a third charging parameter, and the charging method further includes:

[0090] When the trigger temperature interval is less than the first charging temperature threshold, the charging parameter corresponding to the trigger temperature interval is the first charging parameter;

[0091] When the trigger temperature interval is greater than the first charging temperature threshold and less than the second charging temperature threshold, the charging parameter corresponding to the trigger temperature interval is the second charging parameter;

[0092] When the trigger temperature interval is greater than the second charging temperature threshold, the charging parameter corresponding to the trigger temperature interval is the third charging parameter.

[0093] In one example, the first charging temperature threshold is 38°C, and the second charging temperature threshold is 41°C. As shown in Table 1 in the above embodiment, the charging currents corresponding to charging gears 1, 2, and 3 are the first charging parameters, the charging currents corresponding to charging gears 4 are the second charging parameters, and the charging currents corresponding to charging gears 5, 6, and 7 are the third charging parameters.

[0094] In an exemplary embodiment of the present disclosure, at an ambient temperature of 25°C, the maximum surface temperature acceptable to the user is 39°C, and the first charging temperature threshold is 38°C; at an ambient temperature of 35°C, the maximum surface temperature acceptable to the user is 42°C, and the second charging temperature threshold is 41°C. Table 1 above is the correspondence between the charging gear, trigger temperature, reset temperature and charging current determined according to the charging method of the present disclosure, and the electronic device 1 is charged with the screen off according to Table 1. Table 2 is the correspondence between the charging gear, trigger temperature, reset temperature and charging current determined according to the charging method for controlling the temperature of the whole machine in the related art, and the electronic device 2 is charged with the screen off according to Table 2. Among them, the electronic device 1 and the electronic device 2 have the same charging starting power and belong to the same model of electronic devices.

Figure 3A It can be seen that the charging current gradually decreases as the surface temperature increases. At the 38.5°C position, the charging current drops to 6A, and the highest surface temperature at this position is 38.5°C. When the charging capacity reaches 100% of the full capacity, the required charging time is 40 minutes.

[0098] Figure 3B 2 is a schematic diagram of the charging process of an electronic device 1 at an ambient temperature of 25°C according to an exemplary embodiment. The left vertical axis is the charging current, the right vertical axis is the surface temperature of the electronic device, the horizontal axis is the charging time, the upper curve is the curve of the surface temperature change, and the lower curve is the curve of the charging current change. Figure 3B It can be seen that the charging time of electronic devices is between 800s and 1700s. Since the charging current difference between the 37.8℃ and 38.5℃ gears is large, the charging current and surface temperature show an oscillation phenomenon. When the charging current is 6.6A, the surface temperature will rise and enter the 38.5℃ gear. When the charging current drops to 5A, the surface temperature will begin to drop due to the decrease in charging current until it returns to around 37.8℃ and returns to the charging current of 6.6A. The charging cycle is repeated over and over again, and the final surface temperature is as high as 38.5℃. At this time, since the charging time will be longer when charging with a charging current of 6.6A, when the charging capacity reaches 100% of the full capacity, the required charging time becomes shorter, and the required charging time is 38min, which is 38min. Figure 3A The solution in the related art shortens the time by 2 minutes.

[0099] Figure 4A 35°C ambient temperature, the charging process of the electronic device 2 is shown in accordance with an exemplary embodiment. The left vertical axis is the charging current, the right vertical axis is the surface temperature of the electronic device, the horizontal axis is the charging time, the upper curve is the surface temperature curve, and the lower curve is the charging current curve. Figure 4A It can be seen that as the surface temperature gradually increases, the charging current gradually decreases. Most of the time, the charging current is 4.4A (within the time period of 1000s to 3000s), and the highest surface temperature is 41.7°C. When the charging capacity reaches 100% of the full capacity, the required charging time is 58 minutes.

[0100] Figure 4B 1 is a schematic diagram of the charging process of an electronic device 1 at an ambient temperature of 35°C according to an exemplary embodiment. The left vertical axis is the charging current, the right vertical axis is the surface temperature of the electronic device, the horizontal axis is the charging time, the upper curve is the curve of the surface temperature change, and the lower curve is the curve of the charging current change. Figure 4B It can be seen that during the period of 1000s to 3000s, the charging current oscillated between 5A and 2.6A. After the surface temperature exceeded 41.5°C, the charging current was switched to 2.6A, the surface temperature dropped, and the charging current quickly returned to 5A. The charging cycle was repeated, and the final surface temperature reached a maximum of 41.3°C, which was lower than Figure 4A The highest temperature reached by the surface temperature in the related art. At this time, since the charging time for charging with a 5A charging current is longer, when the charging capacity reaches 100% of the full capacity, the required charging time becomes shorter, and the required charging time is 55 minutes, which is shorter than Figure 4A The solution in the related art shortens the time by 3 minutes.

[0101] It can be seen that compared with the charging method in the related art, the charging method in the embodiment of the present disclosure can improve the charging speed and shorten the charging time without increasing the maximum temperature reached by the surface temperature of the electronic device, or even while lowering the maximum temperature reached by the surface temperature of the electronic device.
