Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
The terminal device may be implemented in various forms. For example, the terminal device described in the embodiments of the present application may include a mobile terminal such as a smart phone, a tablet computer, a notebook computer, a palmtop computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a Portable device, and a stationary terminal such as a Digital television, a desktop computer, and the like. It will be understood by those skilled in the art that embodiments according to the present application may be applied to both mobile type terminals and fixed type terminals, except for elements specifically used for mobile purposes, and the embodiments of the present application are not particularly limited.
Taking a mobile terminal as an example, along with the higher integration level of mobile terminals such as smart phones, the requirements of users on functions are stronger and stronger, and at this time, the requirements of users on batteries of the mobile terminals are higher and higher. Since the development of battery technology is relatively slow, the temperature rise during charging of a battery in a mobile terminal is very significant. In particular, if a high power charging is performed on a small-sized mobile terminal, without a perfect temperature control mechanism, poor user experience and even safety problems may be caused due to overheating of the mobile terminal.
In practice, there have been several charging temperature control schemes: the first scheme is an overheating protection scheme, namely, the charging is stopped after the temperature reaches a certain preset value; the second scheme is a scheme of limiting the charging current, that is, after the battery temperature is detected to exceed a specific threshold, the battery power is detected and a background running program is executed to determine whether to change another set of preset charging current. However, the current charging temperature control scheme still has some drawbacks, such as: for the first scheme, a preset value of general overheating protection is set to be higher, before the overheating protection is triggered, the temperature is high, even a user may feel scorching when touching the mobile terminal, and the user experience is seriously influenced; for the second scheme, another set of preset charging currents is changed as three conditions need to be satisfied simultaneously: when the temperature exceeds a specific threshold value, the electric quantity reaches a preset electric quantity value, and a specific program runs in a background; in this way, if only the temperature exceeds a certain threshold but other conditions are not met, the operation of adjusting the charging current is not performed at this time, which may cause the temperature of the mobile terminal to be too high to affect the user experience; or, the temperature exceeds a certain threshold, and the charging current is shifted down by one, but when the charging current is charged, the temperature still cannot be lowered below the expected value, the temperature of the mobile terminal is still too high to affect the user experience, and even a safety problem is caused when the temperature is too high.
The embodiment of the application provides a charging control method, which is applied to a charging control device, and the charging control device is integrated in a terminal device. Detecting the battery temperature of a battery in the terminal equipment; determining a temperature interval and a charging strategy corresponding to the temperature interval based on the detected battery temperature; adjusting the charging current of the battery according to the determined charging strategy, and charging the battery according to the adjusted charging current; when the charging time of the battery by the adjusted charging current meets a preset time threshold, continuously detecting the battery temperature of the battery to control the charging current of the battery; therefore, according to the detected battery temperature, the temperature interval and the corresponding charging strategy can be determined, so that the charging current of the battery can be adjusted, and as long as the detected battery temperature is in the temperature interval, the charging current of the battery can be continuously adjusted according to the corresponding charging strategy, so that the temperature rise of the battery can be effectively controlled, the safety problem caused by overhigh temperature rise can be avoided, and the use safety of the terminal equipment is ensured.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic flow chart of a charging control method provided in an embodiment of the present application is shown. As shown in fig. 1, the method may include:
s101: detecting the battery temperature of a battery in the terminal equipment;
it should be noted that the charging control method according to the embodiment of the present application is applied to a charging control apparatus, and the charging control apparatus may be integrated in a terminal device. In addition, a temperature detection component, such as a temperature sensor, a thermocouple or a thermistor, can also be arranged inside the terminal device; the battery temperature on the battery in the terminal equipment can be detected and obtained through the temperature detection component.
Taking a thermistor as an example, the thermistor may be built in the battery, and after the voltage value of the thermistor is obtained, the battery temperature of the battery may be obtained. Specifically, according to the characteristic that the resistance value of the thermistor is influenced by the temperature, when the temperature changes, the resistance value of the thermistor also changes correspondingly; after the voltage value of the thermistor is obtained, the resistance value of the thermistor can be calculated according to the voltage value, and therefore the battery temperature of the battery can be obtained according to the resistance value.
It should be noted that, before detecting the battery temperature of the battery in the terminal device, it may also be determined whether the terminal device is in a charging state; if the judgment result is yes, executing step S101; otherwise, if the judgment result is negative, the charging control flow is ended.
In this way, when the terminal device is in a charging state, the battery in the terminal device is charged by an external charging device (such as a wired charging device or a wireless charging device), and at this time, the battery temperature of the battery can be detected in order to avoid the temperature of the terminal device, particularly the battery temperature, being too high. Those skilled in the art can understand that, according to the law of energy conversion and conservation, the corresponding relationship between the charging current of the battery in the terminal device and the battery temperature can be obtained, specifically, the larger the charging current, the higher the battery temperature; therefore, the charging current can be adjusted to control the temperature of the battery.
S102: determining a temperature interval and a charging strategy corresponding to the temperature interval based on the detected battery temperature;
it should be noted that, after the battery temperature is detected, the detected battery temperature may be compared with a preset temperature threshold, so as to determine a temperature interval and a charging strategy corresponding to the temperature interval.
Here, the preset temperature threshold may include a first temperature threshold, a second temperature threshold, and a third temperature threshold, and the first temperature threshold is greater than the second temperature threshold, and the second temperature threshold is greater than the third temperature threshold. In the embodiment of the present application, the first temperature threshold, the second temperature threshold, and the third temperature threshold may be set according to actual situations, for example, the first temperature threshold may be 40 ℃, the second temperature threshold may be 39 ℃, and the third temperature threshold may be 37 ℃, but the embodiment of the present application is not particularly limited.
Correspondingly, the temperature intervals may include a first temperature interval, a second temperature interval, a third temperature interval, and the like; the first temperature interval may represent a temperature range greater than or equal to a first temperature threshold, the second temperature interval may represent a temperature range smaller than a second temperature threshold, and the third temperature interval may represent a temperature range smaller than the first temperature threshold and greater than or equal to the second temperature threshold, that is, the third temperature interval may represent a temperature range between the first temperature threshold and the second temperature threshold. Here, it is assumed that the first temperature threshold may be 40 ℃ and the second temperature threshold may be 39 ℃; correspondingly, the first temperature interval may be a temperature range greater than or equal to 40 ℃, the second temperature interval may be a temperature range less than 39 ℃, and the third temperature interval may be a temperature range between 39 ℃ and 40 ℃, but the embodiment of the present application is not particularly limited.
It should be further noted that the first temperature interval and the second temperature interval indicate temperature ranges that do not satisfy the requirement of the battery temperature, and when the detected battery temperature meets the first temperature interval or the second temperature interval, different charging strategies need to be adopted to adjust the charging current of the battery at this time, and then the battery is charged according to the adjusted charging current, so as to control the detected battery temperature to meet the third temperature interval.
In some embodiments, for S102, the determining a temperature interval and a charging strategy corresponding to the temperature interval based on the detected battery temperature may include:
if the detected battery temperature accords with a first temperature interval, determining a first charging strategy corresponding to the first temperature interval; the first charging strategy represents that the charging current of the battery is subjected to descending adjustment according to a first preset value;
if the detected battery temperature accords with a second temperature interval, determining a second charging strategy corresponding to the second temperature interval; and the second charging strategy represents that the charging current of the battery is subjected to rising adjustment according to a second preset value.
It should be noted that each temperature interval corresponds to a different charging strategy; for example, the first temperature interval corresponds to a first charging strategy, and the second temperature interval corresponds to a second charging strategy. Here, the first charging strategy indicates that the charging current of the battery is adjusted to be decreased according to a first preset value, and the second charging strategy indicates that the charging current of the battery is adjusted to be increased according to a second preset value; according to different charging strategies, the charging current of the battery can be adjusted differently, so that the battery temperature of the battery can be controlled.
It should be noted that the first preset value and the second preset value may be the same or different. Wherein the first preset value represents an adjustment value each time the charging current is decreased, and the second preset value represents an adjustment value each time the charging current is increased. Specifically, the charging current may be adjusted by adjusting the charging duty cycle, for example, decreasing the charging duty cycle according to a first preset value, which may be 5% Pmax; the charging current is increased by increasing the charging duty ratio according to a second preset value, which may be 1% × Pmax, where Pmax represents the maximum charging duty ratio allowed for the battery without considering the temperature factor. In addition, the charging current may be adjusted by directly decreasing or increasing the current value, for example, the charging current may be decreased according to a first preset value, where the first preset value may be 5% Ipeak; the charging current is increased according to a second preset value, which may be 1% Ipeak, where Ipeak represents the maximum charging current value allowed for the battery without considering temperature factors. That is to say, the adjustment manner of the charging current, the first preset value and the second preset value can be set according to actual situations, and the embodiment of the present application is not particularly limited.
Thus, assuming that the first temperature threshold may be 40 ℃ and the second temperature threshold may be 39 ℃, the first temperature interval is a temperature range greater than or equal to 40 ℃, the second temperature interval is a temperature range less than 39 ℃, and the third temperature interval is a temperature range between 39 ℃ and 40 ℃; thus, if the detected battery temperature is greater than or equal to 40 ℃, it can be determined that the battery temperature meets the first temperature interval, at this time, because the battery temperature is too high, the charging current needs to be reduced, that is, a first charging strategy is adopted, that is, the charging current of the battery is reduced and adjusted according to a first preset value, and then the battery is charged according to the adjusted charging current; however, if the detected battery temperature is less than 39 ℃, it may be determined that the battery temperature meets the second temperature interval, and at this time, since the battery temperature is relatively low, the charging current needs to be increased, that is, a second charging strategy is adopted, that is, the charging current of the battery is adjusted to be increased according to a second preset value, and then the battery is charged according to the charging current at the current time.
In addition, the third temperature interval may represent a temperature range satisfying a battery temperature demand, and if the detected battery temperature meets the third temperature interval, there is no need to adjust the charging current of the battery at this time. That is, if the detected battery temperature is in the third temperature interval, the charging current of the battery at the current time is maintained, and the battery is charged according to the charging current at the current time.
Specifically, if the detected battery temperature is greater than or equal to 39 ℃ and less than 40 ℃, it may be determined that the battery temperature meets the third temperature interval, which indicates that the battery temperature meets the battery temperature requirement, and at this time, the charging current of the battery at the current moment may be maintained without reducing the charging current or increasing the charging current, and then the battery is charged according to the charging current at the current moment.
S103: adjusting the charging current of the battery according to the determined charging strategy, and charging the battery according to the adjusted charging current;
it should be noted that, after the battery temperature is detected, the detected battery temperature may be compared with a preset temperature threshold, so as to determine a temperature interval and a charging strategy corresponding to the temperature interval; wherein, different temperature intervals correspond to different charging strategies; therefore, after the temperature interval is determined, the charging current of the battery can be adjusted according to the charging strategy corresponding to the temperature interval, and then the battery is charged according to the adjusted charging current.
Optionally, in some embodiments, when the detected temperature of the battery conforms to the first temperature interval, for S103, adjusting the charging current of the battery according to the determined charging strategy, and charging the battery according to the adjusted charging current, may include:
the charging current of the battery is subjected to descending adjustment according to a first preset value to obtain a first charging current;
and charging the battery according to the first charging current.
Optionally, in some embodiments, when the detected temperature of the battery conforms to the second temperature interval, for S103, adjusting the charging current of the battery according to the determined charging strategy, and charging the battery according to the adjusted charging current, may include:
the charging current of the battery is subjected to rising adjustment according to a second preset value to obtain a second charging current;
and charging the battery according to the second charging current.
It should be noted that, for the second temperature interval, the second temperature interval may be further divided into a first sub-temperature interval and a second sub-temperature interval by a third temperature threshold; the first sub-temperature interval may represent a temperature range between the second temperature threshold and the third temperature threshold, and the second sub-temperature interval may represent a temperature range smaller than the third temperature threshold. For example, assuming that the third temperature threshold may be 37 ℃, the first sub-temperature interval may be a temperature range between 37 ℃ and 39 ℃, and the second sub-temperature interval may be a temperature range less than 37 ℃.
It is understood that, for the second temperature interval, it may be further determined whether the detected battery temperature is greater than or equal to the third temperature threshold, that is, whether the detected battery temperature meets the first sub-temperature interval or the second sub-temperature interval, and then further determine how to adjust the charging current of the battery. Therefore, in some embodiments, when it is determined that the temperature interval is a second temperature interval, the performing a rising adjustment on the charging current of the battery according to a second preset value to obtain a second charging current may include:
determining whether the detected battery temperature is greater than or equal to a third temperature threshold; wherein the third temperature threshold is less than the second temperature threshold;
if the detected battery temperature is greater than or equal to the third temperature threshold, judging whether a preset parameter value is greater than or equal to a preset constant;
if the preset parameter value is larger than or equal to the preset constant or the detected battery temperature is smaller than the third temperature threshold value, setting the preset parameter value to be equal to 1, and performing rising adjustment on the charging current of the battery according to a second preset value to obtain a second charging current so as to charge the battery according to the second charging current.
Further, after determining whether the preset parameter value is greater than or equal to the preset constant, the method may further include:
and if the preset parameter value is smaller than the preset constant, adding 1 to the preset parameter value, and updating the preset parameter value by using the processed preset parameter value.
It should be noted that, for the second temperature interval, it may be further determined whether the detected battery temperature is greater than or equal to a third temperature threshold, so that the detected battery temperature is divided into a first sub-temperature interval and a second sub-temperature interval by the third temperature threshold; here, the first sub-temperature section may indicate a temperature range corresponding to a temperature greater than or equal to the third temperature threshold value, and the second sub-temperature section may indicate a temperature range corresponding to a temperature less than the third temperature threshold value. For example, assuming that the second temperature interval may be a temperature range of less than 39 ℃ and the third temperature threshold may be 37 ℃, the first sub-temperature interval may be a temperature range between 37 ℃ and 39 ℃ and the second sub-temperature interval may be a temperature range of less than 37 ℃.
It should be further noted that, if the detected battery temperature is greater than or equal to the third temperature threshold, the detected battery temperature conforms to the first sub-temperature interval; at this time, a preset parameter value can be set, and then whether the preset parameter value is larger than or equal to the preset constant or not is judged. In the charging process, the initial default value of the preset parameter value may be set to 0, and the preset constant may be set to 6, but the embodiment of the present application is not particularly limited.
That is, before the step S101 is performed for the first time, the method may further include: the preset parameter value is set equal to 0.
Thus, if the detected battery temperature is in accordance with the first sub-temperature interval, since the battery temperature is not too low, the charging current can be very slowly adjusted at this time, that is, it is first determined whether the preset parameter value is greater than or equal to the preset constant (for example, 6), if the preset parameter value is less than the preset constant, the preset parameter value is subjected to the processing of adding 1, and in the process, the charging current at the current moment is maintained to charge the battery; after a plurality of cycle detection periods (for example, 6 cycle periods) pass, that is, when the preset parameter value is equal to the preset constant, the charging current of the battery may be adjusted to rise according to a second preset value at this time to obtain a second charging current, and then the battery is charged according to the second charging current; and meanwhile, setting the preset parameter value to be 1, and judging whether the charging current is adjusted in the next round. However, when the detected battery temperature is within the second sub-temperature range, the charging current may be directly adjusted at this time due to the excessively low battery temperature, that is, the charging current of the battery is directly adjusted according to the second preset value to obtain the second charging current, and then the battery is charged according to the second charging current.
S104: and when the charging time of the adjusted charging current to the battery meets a preset time threshold, continuously detecting the battery temperature of the battery so as to continuously adjust the charging current of the battery.
It should be noted that, after the charging current is adjusted according to the determined charging strategy, an adjusted charging current, such as a first charging current or a second charging current, may be obtained; then charging the battery according to the adjusted charging current; at this time, the charging time of the adjusted charging current to the battery can be judged to meet a preset time threshold; when the charging time of the battery by the adjusted charging current satisfies the preset time threshold, S101 may be continuously performed, that is, the battery temperature of the battery is continuously detected to continuously adjust the charging current of the battery.
Optionally, in some embodiments, when the detected battery temperature meets a first temperature interval, for S104, when the charging time of the adjusted charging current for the battery meets a preset time threshold, continuing to detect the battery temperature of the battery to control the charging current of the battery may include:
and when the charging time of the first charging current to the battery meets a preset time threshold, continuously detecting the battery temperature of the battery, and continuously controlling the charging current of the battery according to the detected battery temperature.
Optionally, in some embodiments, when the detected battery temperature meets a second temperature interval, for S104, when the charging time of the adjusted charging current to the battery meets a preset time threshold, continuing to detect the battery temperature of the battery to control the charging current of the battery, including:
and when the charging time of the battery by the second charging current meets a preset time threshold, continuously detecting the battery temperature of the battery, and continuously controlling the charging current of the battery according to the detected battery temperature.
It should be noted that the preset time threshold may be set according to actual situations, for example, the preset time threshold may be set to 10 seconds (denoted by s), but the embodiment of the present application is not particularly limited.
It should be noted that, for the determination of the charging time, a counter may be used for timing. That is, when the battery is charged according to the adjusted charging current, the counter is synchronously started; when the timing of the counter meets a preset time threshold (for example, 10s), the battery temperature of the battery can be detected again at this time, and then the temperature interval and the charging strategy corresponding to the temperature interval are determined again according to the detected battery temperature; and adjusting the charging current of the battery again according to the determined charging strategy, and charging the battery according to the adjusted charging current.
In the embodiment of the present application, when the detected temperature of the battery meets the second temperature interval, the charging current of the battery may be increased according to a second preset value at this time, but the charging current after the final increase adjustment cannot be higher than the upper limit value of the charging current (which may be represented by Ipeak), and the charging current does not continue to increase after increasing to the upper limit value; here, the upper limit value is a maximum charging current allowed for the battery regardless of the temperature factor. In addition, when the detected battery temperature meets the first temperature interval, the charging current of the battery can be reduced and adjusted according to a first preset value, but the charging current after final reduction and adjustment cannot be lower than the lower limit value of the charging current, and the charging current does not continue to be reduced after the charging current is reduced to the lower limit value; here, the lower limit value may be set to 30% Ipeak, may also be set to 0 (i.e., the off-state of charge), and may also be set to a certain current value, but the embodiment of the present application is not particularly limited.
In addition, when the detected battery temperature meets the third temperature interval, the battery temperature at the moment is shown to meet the battery temperature requirement, and the charging current of the battery is not required to be adjusted, namely the charging current at the current moment is maintained to charge the battery; therefore, if the charging time of the battery by the charging current at the current moment meets the preset time threshold, the battery temperature of the battery can still be continuously detected, and the charging current of the battery is continuously controlled according to the detected battery temperature, so that the temperature rise of the battery can be effectively controlled by detecting the battery temperature of the battery and continuously adjusting the charging current of the battery according to the corresponding charging strategy, and the safety problem caused by over-high temperature rise is avoided.
The embodiment provides a charging control method, which comprises the steps of detecting the battery temperature of a battery in terminal equipment; determining a temperature interval and a charging strategy corresponding to the temperature interval based on the detected battery temperature; adjusting the charging current of the battery according to the determined charging strategy, and charging the battery according to the adjusted charging current; when the charging time of the battery by the adjusted charging current meets a preset time threshold, continuously detecting the battery temperature of the battery to control the charging current of the battery; therefore, according to the detected battery temperature, the temperature interval and the corresponding charging strategy can be determined, so that the charging current of the battery can be adjusted, and as long as the detected battery temperature is in the temperature interval, the charging current of the battery can be continuously adjusted according to the corresponding charging strategy, so that the temperature rise of the battery can be effectively controlled, the safety problem caused by overhigh temperature rise can be avoided, and the use safety of the terminal equipment is ensured.
Based on the same inventive concept of the foregoing embodiment, refer to fig. 2, which shows a detailed flowchart of a charging control method provided in an embodiment of the present application. As shown in fig. 2, the detailed process may include:
s201: setting n to 0;
note that n represents a preset parameter value. Before step S202 is performed for the first time, the preset parameter value may be set equal to 0. Thus, it can be determined whether the charging current of the battery needs to be adjusted by determining whether n is greater than or equal to 6.
S202: detecting the battery temperature T of the battery;
it should be noted that the first temperature threshold may be 40 ℃, the second temperature threshold may be 39 ℃, and the second temperature threshold may be 37 ℃; thus, T is more than or equal to 40 ℃ and represents a first temperature interval, T is less than 39 ℃ and represents a second temperature interval, and T is more than or equal to 39 ℃ and less than 40 ℃ and represents a third temperature interval. In this way, according to the detected battery temperature T, a temperature interval and a corresponding charging strategy can be determined so as to control the charging current of the battery.
S203: judging whether T is more than or equal to 40 ℃;
s204: if the determination result is yes, performing descending adjustment on the charging current of the battery according to a first preset value to obtain a first charging current, and then executing the step S212;
s205: if the judgment result is negative, judging whether T is more than or equal to 39 ℃;
s206: if yes, maintaining the charging current of the battery at the current moment, and then executing the step S212;
it should be noted that, after the battery temperature T is detected, if the detected battery temperature T is greater than or equal to 40 ℃, it may be determined that the battery temperature is in accordance with the first temperature interval, at this time, because the battery temperature is too high, the charging current needs to be reduced, that is, a first charging strategy is adopted, that is, at this time, step S204 needs to be executed, that is, the charging current of the battery is reduced and adjusted according to the first preset value, and then the battery is charged according to the adjusted charging current; if the detected battery temperature T is greater than or equal to 39 ℃, it may be determined that the battery temperature corresponds to a third temperature interval, and since the third temperature interval represents a temperature range satisfying the battery temperature requirement, the charging current of the battery does not need to be adjusted at this time, that is, step S206 needs to be performed, i.e., the charging current of the battery at the current time is maintained, and the battery is charged according to the charging current at the current time.
S207: if the judgment result is negative, judging whether T is more than or equal to 37 ℃;
s208: if the judgment result is yes, judging whether n is more than or equal to 6;
s209: if the determination result is no, executing n-n +1, and then executing step S212;
s210: the charging current of the battery is adjusted in a rising mode according to a second preset value to obtain a second charging current;
s211: setting n to 1;
it should be noted that, after step S207, if the determination result is no, that is, T <37 ℃, step S210 and step S211 are executed, and then step S212 is executed; after step S208, if the judgment result is yes, i.e. n ≧ 6, step S210 and step S211 are also executed, and then step S212 is executed.
It should be further noted that, after the battery temperature T is detected, if the detected battery temperature T is less than 39 ℃, it may be determined that the battery temperature meets the second temperature interval; whether the detected battery temperature T is greater than or equal to 37 ℃ can be further judged, namely the second temperature interval is divided into a first sub-temperature interval and a second sub-temperature interval; wherein T <39 ℃ is greater than or equal to 37 ℃ and represents a first sub-temperature interval, and T <37 ℃ represents a second sub-temperature interval, so that the adjustment of the charging current of the battery can be further determined.
That is, if the detected battery temperature meets the first sub-temperature interval (37 ℃ ≦ T <39 ℃), since the battery temperature is not too low, the charging current may be adjusted very slowly at this time, i.e., it is first necessary to perform step S208, i.e., determine whether n is greater than or equal to 6; if n is less than 6, adding 1 to n, and maintaining the charging current at the current moment to charge the battery in the process; after 6 cycle detection periods, that is, when n is equal to 6, steps S210 and S211 need to be executed at this time, that is, the charging current of the battery is adjusted to rise according to the second preset value to obtain a second charging current, then the battery is charged according to the second charging current, and meanwhile, the preset parameter value is set to 1, so as to determine whether to adjust the charging current in the next round. However, if the detected battery temperature is in accordance with the second sub-temperature interval (T <37 ℃), since the battery temperature is too low, the charging current may be directly adjusted at this time, that is, steps S210 and S211 are directly performed, the charging current of the battery is adjusted to increase according to the second preset value to obtain the second charging current, and then the battery is charged according to the second charging current, and meanwhile, the preset parameter value is set to 1, so as to determine whether to adjust the charging current in the next round.
S212: when the charging time of the battery satisfies the preset time threshold, the step S202 is continuously performed.
It should be noted that, after the charging current is adjusted according to the determined charging policy, the battery is continuously charged, and at this time, it is also necessary to determine whether the charging time of the battery meets a preset time threshold (for example, 10 seconds); in this way, when the charging time of the battery satisfies the preset time threshold, S202 may be continuously performed, that is, the battery temperature T is continuously detected for continuously adjusting the charging current of the battery to achieve the control of the battery temperature.
It should be further noted that, the temperature threshold (for example, the first temperature threshold, the second temperature threshold, or the third temperature threshold), the temperature interval (for example, the first temperature interval, the second temperature interval, or the third temperature interval), and the preset value (for example, the first preset value or the second preset value) for adjusting the battery charging current may be set according to actual situations, that is, no matter the temperature is 40 ℃, or 39 ℃, or 37 ℃, which is not specifically limited in the embodiments of the present application. That is to say, the charging control method according to the embodiment of the present application can be applied to different temperature zones or different charging current gear adjustments; in addition, part of the flow shown in fig. 2 (for example, steps S208 and S209) may be deleted or simplified, and the method is still applicable to the charging control method according to the embodiment of the present application.
In the embodiment of the application, compared with the terminal device only having the over-temperature protection function, the charging control method in the embodiment of the application can control the temperature of the battery or the temperature of the shell within a preset range, so that the user experience cannot be influenced due to the over-high temperature of the terminal device, and the terminal device can be continuously charged; in addition, as long as the battery temperature does not conform to the preset range, the charging control method of the embodiment of the application can continuously adjust the charging current according to the detected battery temperature so as to realize the control of the battery temperature.
The embodiment provides a charging control method, which elaborates the specific implementation of the foregoing embodiment, and it can be seen that, by the technical solution of the foregoing embodiment, the charging current of the battery can be adjusted, and as long as the detected battery temperature is within the temperature range, the charging current of the battery can be continuously adjusted according to the corresponding charging policy, so that the temperature rise of the battery can be effectively controlled, and the safety problem caused by the excessively high temperature rise can be avoided, thereby ensuring the use safety of the terminal device.
