In step 201, in charging process, the current temperature in acquisition terminal earphone component detected by temperature sensor Degree.

In the present embodiment, terminal includes charging inlet and the headset assembly being disposed adjacent with the charging inlet.

Wherein, the charging inlet of terminal can be USB (Universal Serial Bus, USB) Type-C The interface of the types such as interface, Micro USB interfaces or Lighting interfaces.The charging inlet can by USB data line with fill Electrical equipment is connected, and charger provides the terminal with electric energy, charged with to terminal by USB data line.Charged to terminal During, as shown in Figure 2 B, charging current is by charger for the flow direction of charging current between the charging inlet and charger of terminal The voltage bus pin (VBUS) of interface flows to the voltage bus pin of terminal charge interface.Terminal also includes charging circuit, should Charging circuit is connected with charging inlet and battery, for the electric energy of acquisition to be supplied into battery, to realize the charging to battery. Charging current is flowed to the grounding pin of charger interface by the grounding pin (GND) of terminal so that the battery of charger and terminal Between form charge circuit.And in charging process, if the charging inlet of terminal has foreign conducting matter, or terminal is in Moist environment, it is likely that terminal short circuit at charging inlet can be made, now, a part of charging current is directly connect by terminal charge The voltage bus pin of mouth flows to the grounding pin of terminal charge interface.It should be noted that the charging inlet of terminal can set Put in the bottom of terminal, top or lateral edges, the present embodiment is not construed as limiting to this.

Wherein, temperature sensor, earphone interface (being referred to as receiver J-Horner) are provided with headset assembly and are used for Earphone interface is coordinated to realize the electronic component of audio signal input/output function, such as modulus conversion chip, digital-to-analogue conversion core Piece and audio signal amplifier etc..Wherein, the distance between the temperature sensor and charging inlet are in the effective of temperature sensor In temperature detection range, that is to say that the charging inlet of terminal is located in the effective temperature detection range of temperature sensor so that should The temperature of temperature sensor detection can represent the temperature of charging inlet.It should be noted that in headset assembly, TEMP Device can be arranged on the position adjacent with the outside of earphone interface, it is also possible to be arranged on earphone interface, with test earphone interface Temperature.The headset assembly is desirably integrated into charging circuit, and now, earphone interface can be integrated with charging inlet, It is that the charging inlet both can be used for connecting charger, it is also possible to the ear speaker device for connecting outside.

A kind of plan view from above of the terminal provided referring to Fig. 2 C, is only located in terminal bottom in figure with charging inlet Portion, the temperature sensor of headset assembly are arranged on the position adjacent with charging inlet upper right side to exemplify.It should be noted that The present embodiment is integrally not construed as limiting to headset assembly with the relative position of charging inlet, such as, headset assembly integrally may be located at The left side or right side of charging inlet, certainly, when the earphone interface of headset assembly is integrated with the charging inlet, the charging The position of mouth is just arranged on headset assembly inside etc..

In the present embodiment, when terminal is detected is converted to charged state by non-charged state, the TEMP is started Device carries out temperature detection, and the temperature that the temperature sensor can be in real time to charging inlet is detected.Terminal can periodically from this Temperature sensor obtains the temperature of the charging inlet, such as, terminal can be obtaining a temperature for charging inlet each second.Terminal The temperature of charging inlet that can be to obtaining each time is recorded, such as, in a charging process, terminal will be obtained each time The temperature of the charging inlet for taking is corresponding with the corresponding acquisition time to be stored.Wherein, a charging process can be examined for terminal Measure and charged state is entered by non-charged state, to the process for being again introduced into non-charged state.It should be noted that ought once fill At the end of electric process, that is to say, when detecting the terminal and being converted to non-charged state by charged state, in order to reduce terminal consumption Can, terminal can also control the temperature sensor to stop carrying out temperature detection.

It should be noted that can also start the temperature sensor when the headset assembly of terminal is in running order, to survey The temperature of earphone interface is measured, the performance of headset assembly is calibrated with the temperature according to the measurement, so that under various circumstances Ensure the voice frequency listening effect of stabilization.If terminal by non-charged state when charged state is converted to, the headphone set is detected The temperature sensor of part has been started up, then without performing the step of starting the temperature sensor again.In addition, in order to avoid headphone set Heat production is impacted to the temperature detection of charging inlet in part itself course of work, in charging process, if terminal is detected During audio broadcast state or talking state under headset mode, user can be pointed out to exit audio playing function, such as moved back Go out audio player, with the security of intensified charging process.

In step 202., detect whether the Current Temperatures meet predetermined current adjusting condition.

In the present embodiment, when the Current Temperatures meet predetermined current adjusting condition, terminal there may be potential safety hazard, Such as terminal temperature is too high to damage terminal component, or even causes and catch fire.Can be by following two kinds of sides in implementation process Formula detects whether the Current Temperatures of charging inlet meet predetermined current adjusting condition:

First way, whether the Current Temperatures are detected higher than preset temperature threshold value, if the Current Temperatures are higher than default Temperature threshold, it is determined that the Current Temperatures meet predetermined current adjusting condition.

Wherein, preset temperature threshold value is more than or equal to the maximum for charging normal temperature range, and this charges normal temperature Scope can be obtained by the way that different terminals are carried out with the experimental data statistics of charging measurement, and certain terminal can also be according to actual need The preset temperature threshold value is modified, the present embodiment is not construed as limiting to this.When the temperature of charging inlet is higher than the default temperature During degree threshold value, illustrate the temperature of charging inlet beyond charging normal temperature range, it is understood that there may be potential safety hazard.

Whether the second way, the temperature rate-of-rise of detection charging inlet are more than scheduled rate, if should be more than default Speed, it is determined that the temperature of the charging inlet meets predetermined current adjusting condition.

Wherein, the determination mode of the temperature rate-of-rise of charging inlet can be:Obtain the historical temperature of charging inlet, root According to the Current Temperatures and the historical temperature of the charging inlet, the temperature rate-of-rise of the charging inlet is determined.Such as, terminal can From the corresponding relation of the temperature for obtaining time and charging inlet of storage, to obtain the going through for the previous period of current time History temperature, determines the acquisition time interval of difference, historical temperature and the Current Temperatures of historical temperature and Current Temperatures, by the difference With the ratio of the time interval as charging inlet temperature rate-of-rise.Wherein, scheduled rate can be by different terminals The experimental data statistics for carrying out charging measurement is obtained, and certain terminal can also be repaiied to the scheduled rate according to actual needs Change, the present embodiment is not construed as limiting to this.When the temperature rate-of-rise of charging inlet is more than scheduled rate, the charging inlet is illustrated Temperature continuously steeply rise, it is likely that there is potential safety hazard.

In the second way, terminal it could also be because that some outside causes cause the temperature of charging inlet temporarily Rapidly rise, soon fall after rise to normal temperature range afterwards, may not there is potential safety hazard in the case of this kind.Therefore, it is Improve and detect whether the temperature of charging inlet meets the accuracy of predetermined current adjusting condition in the step 202, terminal may be used also When being more than scheduled rate with the temperature rate-of-rise that charging inlet is determined in continuous n times, then determine that the temperature of charge port meets pre- If electric current adjusting condition.Wherein N is the integer more than 1.

In step 203, if the Current Temperatures meet predetermined current adjusting condition, according to the current temperature of the charging inlet Degree, determines the target charge current value of the terminal.

Wherein, present charging current value of the target charge current value less than terminal.Because target charge current value is less than Present charging current value, the quantity of heat production of charging inlet can be reduced by reducing charging current, so reduce the temperature of terminal with Ensure safe charging.

Wherein, charge controlling chip can be included in the charging circuit of terminal, the charge controlling chip can monitor charging The size of electric current, terminal can obtain present charging current value in real time by the charge controlling chip.

Wherein, according to the Current Temperatures, determine that the process of the target charge current value of terminal can be with:

Terminal determines the temperature adjustment grade belonging to the Current Temperatures of charging inlet according to the Current Temperatures of charging inlet, Target charge current value is determined according to the temperature adjustment grade.

Wherein, whether the two ways of predetermined current adjusting condition, the root are met for detection Current Temperatures in step 202 According to the Current Temperatures, determine that the temperature adjustment grade belonging to the Current Temperatures is also corresponded to as follows with two ways:

First way in first way, this kind of mode correspondence above-mentioned steps 202, terminal can be with this kind of mode Multiple temperature adjustment grades are preset, different temperature adjustment grades can correspond to different temperature ranges, when the current temperature When degree falls into certain temperature range, the corresponding temperature adjustment grade of the temperature range is the temperature belonging to the temperature of the charging inlet Degree regulation grade.Wherein, the temperature indicated by temperature range is higher, and the corresponding temperature adjustment grade higher of the temperature range, It is that Current Temperatures are higher, the temperature adjustment grade higher belonging to it.

The second way in the second way, this kind of mode correspondence above-mentioned steps 202, different temperature adjustment grades pair Different speed ranges are answered, in the temperature that charging inlet is determined according to the historical temperature of the Current Temperatures and charging inlet Rise after speed, the speed range belonging to the temperature rate-of-rise is determined, by the speed range pair belonging to the temperature rate-of-rise The temperature adjustment grade answered, is defined as the temperature adjustment grade belonging to Current Temperatures.Wherein, the speed indicated by speed range is got over Height, the temperature adjustment grade higher indicated by the speed range, that is to say, Current Temperatures are higher, temperature adjustment belonging to it etc. Level is higher.

Wherein, according to temperature adjustment grade, determine that target charge current value can be using following two implementation methods come real It is existing:

In one embodiment, a temperature adjustment grade can correspond to a charging current value, temperature adjustment grade Higher, its corresponding charging current value is smaller.Terminal can directly according to the corresponding relation, by the temperature adjustment grade with determination Corresponding charging current value is defined as target charge current value.

Wherein, in order to reduce the temperature of terminal as early as possible, less target can be set when present charging current value is larger Charging current value.For example, the battery normal charging current of 1000mAh (MAH) is 400mA (milliampere) to the maximum, it is assumed that currently fill Correspondence target charge current value 1 when electric current value is 450mA, correspondence target charge current when present charging current value is 470mA Value 2, then target charge current value 1 is less than target charge current value 2.

In another embodiment, a temperature adjustment grade can correspond to an electric current regulated value.Because temperature is adjusted Section grade higher, illustrates that the Current Temperatures of charging inlet are higher, therefore, in order to more quickly lower the temperature to charge port, can be with Charging current is farthest reduced, therefore, in this kind of implementation method, temperature adjustment grade higher, and its corresponding electric current is adjusted Section value is bigger.Terminal is obtained corresponding with the temperature adjustment grade after the temperature adjustment grade belonging to the Current Temperatures is determined Electric current regulated value, the difference of present charging current value and the electric current regulated value is defined as target charge current value.Certainly, mesh Mark charging current value can also be the ratio of present charging current value and the electric current regulated value, in the case of this kind, electric current regulation Value is the numerical value more than or equal to 1, additionally, target charge current value can also be adjusted by present charging current value and first electric current Section value is obtained by other algorithm computings, and the present embodiment is not construed as limiting to this.

It should be noted that when terminal has very serious potential safety hazard, such as when charging inlet is short-circuited, now In order to ensure the safety that charges, it is ensured that terminal is not damaged by, terminal can also forbid charging, and that is to say and for charging current to be reduced to zero. Therefore, it is above-mentioned according to the Current Temperatures, determine the target charge current value of the terminal process can also comprise the following steps a or Step b:

Step a:Whether the Current Temperatures are detected higher than maximum temperature threshold value, if the Current Temperatures are higher than maximum temperature threshold Value, it is determined that the size of the target charge current is zero, forbids terminal to continue to charge.

It should be noted that the maximum temperature threshold value is higher than the preset temperature threshold value mentioned in step 202, when this is current When temperature is higher than maximum temperature threshold value, illustrate that the charging inlet may have occurred short circuit.When in step 202 pass through first way After detecting whether the Current Temperatures meet predetermined current adjusting condition, step a can be performed.

Step b:Obtain in the temperature of the charging inlet determined by the historical temperature of the Current Temperatures and the charging inlet Rise speed;If the temperature rate-of-rise is more than flank speed threshold value, it is determined that the size of the target charge current is zero, is forbidden Terminal continues to charge.

It should be noted that the flank speed threshold value is more than the scheduled rate in the second way of above-mentioned steps 202, when filling When the temperature rate-of-rise of electrical interface is more than the flank speed threshold value, illustrate that the charging inlet may have occurred short circuit.Work as step In 202 after the second way detects whether the Current Temperatures meet predetermined current adjusting condition, step b can be performed.

In step 204, the charging current of the terminal is adjusted to the target charge current by the present charging current value Value.

Terminal can send electric current regulating command to charging equipment, and the electric current regulating command includes the target charge current Value, the target charge current is set to by charger by charging current.

Above-mentioned steps 203 to 204 are when the Current Temperatures of charging inlet meet predetermined current adjusting condition, by terminal Charging current is adjusted to the process of target charge current, so as to avoid charging inlet temperature it is too high when, to terminal cause damage.

The method that the present embodiment is provided, in charging process, comes by using the temperature sensor in terminal earphone component The temperature of charging inlet, and the temperature based on charge port interface are detected, when charging current is excessive, charging current is turned down, protected The safety of charging process has been demonstrate,proved, and terminal saves cost without setting temperature sensor specifically designed for charging inlet.
