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
