Embodiment one
With reference to Fig. 1, the charging method of first embodiment of the invention is proposed.In the embodiment of the present invention, the second charging strategy can
To be interpreted as of the prior art charging normal mode, as filled soon, commonly charging etc..The embodiment of the present invention is at the base of prior art
Setting up the first charging strategy on plinth, the first corresponding charge power of charging strategy is less than the charge power of the second charge power,
By switching flexibly between the first charging strategy and the second charging strategy, carry out the experience of equilibrium charging speed and user.
Described charging method comprises the following steps：
In S11, charging process, the running status of destination application in monitoring terminal.Whether judge destination application
It is in running status, when destination application is in running status, enter step S12；Do not transport when destination application is in
During row state, enter step S13.
Concrete, after detecting that the charging inlet of terminal and charger are connected entrance charged state, then start monitoring eventually
The running status of destination application in end.Described destination application can include talk application program, game application,
Video application, navigation application program, camera application program etc. cause terminal to be generated heat in serious application program when running
One or at least two.Further, any application program can be appointed as destination application by user as required.
It is alternatively possible to set two states, the respectively first state and the second state for destination application.Charged
Cheng Zhong, the state handover event of monitoring objective application program；When destination application is switched to the first state, determine that target should
It is in running status by program；When destination application is switched to the second state, determine that destination application is in off-duty
State.This monitoring mode, consumes energy low, and can detect the running status of destination application in real time.
For example：When destination application is talk application program, the definition state of answering is the first state, hangs up shape
State is the second state, can implant callback interface in talk application program, is cut by callback interface monitoring receiving/hang-up state
The generation changed, when monitor answer state when, determine that talk application program brings into operation, be in running status；When monitoring extension
During disconnected state, determine that talk application EP (end of program) runs, be in off-duty state.When destination application is game application journey
When sequence, video application, navigation application program or camera application program, definition starting state is the first state, exits state
It is the second state, can implant back in game application, video application, navigation application program and camera application program
Adjust interface, started/exit the generation of state switching by callback interface monitoring, when monitoring starting state, determine aforementioned answering
Bring into operation by program, be in running status；When monitor exit state when, determine that aforementioned applications EP (end of program) runs, be in
Off-duty state.
It will be understood by those skilled in the art that can in the way of using other operation shape of monitoring objective application program
State.For example, whether detection destination application is currently currently running in real time, but this mode consumes energy higher.And for example, timing
Whether detection destination application is currently currently running, but this mode real-time is poor, target i.e. can not be detected timely
The running status of application program.
S12, perform the first charging strategy.It in the embodiment of the present invention, is in running status when monitoring destination application
When, then change normal charging modes, perform the first charging strategy, tight to alleviate the terminal brought when destination application runs
The problem retransmitting heat.
It is alternatively possible to take following first charging strategy：Directly restriction charge power is to the first predeterminated level, to reduce
Charge power, reduces caloric value.For example, it is assumed that normal charge power is 20W, when destination application is in running status
After, then limit charge power to 15W
For different destination applications, its corresponding first predeterminated level can be the same or different, i.e. when not
When same destination application runs, charge power can be reduced to identical level or different levels.Can be according to reality
Test, set corresponding power level for different destination applications, for the high application program of caloric value, then set relatively low
Power level, on the contrary then set higher power level.
Alternatively, may also take on following charging strategy：The temperature of detection terminal, when the temperature of terminal is more than first threshold
When, just reduce charge power.This mode will be described in detail in a later process.
Certainly, it will be understood by those skilled in the art that other charging strategy of the prior art can also be used to alleviate
Heating problem, is not repeated herein.
S13, perform the second charging strategy.
When destination application is in off-duty state, then perform the second charging strategy.
Alternatively, when performing the second charging strategy, can directly improve charge power and charge to the second predeterminated level, full speed,
Ensure charging rate.
Alternatively, when performing the second charging strategy, the temperature of detection terminal, as the temperature of terminal reduces, gradually step up
Charge power is to the second predeterminated level.Thus prevent instantaneous raising charge power from causing temperature to rise sharply.
Certainly, in the embodiment of the present invention, the second predeterminated level is higher than the first predeterminated level.
In step S12, the first charging strategy as shown in Figure 2 can be performed, comprise the following steps：
S121, the temperature of detection terminal.Judge whether the temperature of terminal is more than first threshold, when temperature is more than first threshold
When, step S122.
Concrete, when monitor destination application be in running status after, then by temperature sensor in real time or timing
(periodically) temperature of detection terminal appointed part.Temperature is compared described appointed part by be typically to generate heat more serious or user
Sensitive position, it is of course also possible to specify any part as required.
It is alternatively possible to the battery of terminal, screen, central processing unit (Central Processing Unit, CPU),
PMU (Power Management Unit, PMU), graphic process unit (Graphic Processing Unit,
Etc. GPU) any one position in position arranges temperature sensor, detects any one position aforementioned by temperature sensor
Temperature.
Alternatively it is also possible in portions such as the battery of terminal, screen, central processing unit, PMU, graphic process unit
At least two position in Wei arranges temperature sensor, is detected the temperature at aforementioned at least two position by temperature sensor.
It is possible to further specify different temperature detection positions for different destination applications.For example, when call should
When running by program, predominantly detect the temperature of screen, because screen contact face, the therefore temperature to screen when user makes a phone call
Most sensitive；Meanwhile, staff grips terminal bonnet area of cell, therefore can also detect the temperature of battery.And for example, when game application
When program or video application run, predominantly detect the temperature of central processing unit and/or graphic process unit, because playing and regarding
Frequency needs to consume the ample resources of central processing unit and graphic process unit, causes the two device heating amount big.
It will be understood by those skilled in the art that in addition to using temperature sensor and detecting the temperature of terminal, can also adopt
Detect the temperature of terminal with alternate manner of the prior art, be not repeated herein.
In charging process, when the temperature of terminal exceedes certain value, user may feel that uncomfortable, affects user's body
Test, the temperature of terminal can be reduced by reducing charge power, make to this end, the embodiment of the present invention pre-sets first threshold
Higher limit for temperature.First threshold can determine with experimental result according to actual needs, for example, it is possible to set first threshold
It is 40 DEG C.
The corresponding first threshold in the different position of terminal can be the same or different.More sensitive to temperature for user
Position, first threshold can arrange lower, and user is not very sensitive position to temperature, and first threshold can be arranged
Obtain higher.For example, screen is the position that face directly contacts, more sensitive to temperature, therefore can be corresponding with setting screen
First threshold is 37 DEG C；And the positions such as battery center processor, PMU, graphic process unit, it is staff mediate contact
Position, higher to the tolerance level of temperature, therefore can set the corresponding first threshold in these positions as 40 DEG C.
After the temperature of terminal being detected, compare the size of the temperature detecting and first threshold, it is judged that whether temperature is big
In first threshold, when more than threshold value, enter next step S122.
S122, reduction charge power.
Concrete, when temperature terminal being detected is more than first threshold, illustrate that temperature is too high, in order to prevent temperature too high
And affect Consumer's Experience, then reduce charge power, to reduce the temperature of terminal.Concrete, can by reduce charging current or
Person's charging voltage realizes the reduction of charge power.
When have detected the temperature at terminal at least two position, as long as then the temperature at arbitrary position is more than first threshold, then
Reduce charge power；Or, when the temperature at the position of terminal predetermined number is more than first threshold, just reduce charge power.In advance
If quantity can set as required, as being set as one, two, three etc., such as：When the temperature at one position of terminal is more than
First threshold, and when the temperature at other positions is not more than first threshold, then do not reduce charge power；When two positions of terminal or
When the temperature at plural position is more than first threshold, then reduce charge power.
In certain embodiments, the process that terminal reduces charge power is：Reduce in flow process at a power, examine when first
When measuring the temperature of terminal more than first threshold, reduce charge power setting value；Then, with Preset Time as cycle, timing inspection
Testing temperature, as long as temperature is still above first threshold, then continues to reduce charge power, until temperature is less than or equal to first threshold
Till.Wherein, power reduces flow process, reduces charge power i.e. first to the whole process stopping reduction charge power, and one
Individual power reduces flow process may only reduce a charge power, it is also possible to reduce charge power at least twice.
Terminal reduces the idiographic flow of charge power as it is shown on figure 3, comprise the following steps：
S101, detect terminal temperature be more than first threshold, reduce charge power setting value.
This step S101 is to reduce charge power first in a power reduction flow process, reduces the value (amplitude) of charge power
Can set according to actual needs, reduce charge power 2W for example, it is possible to set.It is of course also possible to be set as 1W, 1.5W,
2.5W, 3W, 4W etc., do not limit at this.
S102, with Preset Time as cycle, timing detect terminal temperature.Judge the temperature of terminal whether still above
One threshold value；When the temperature of terminal is still above first threshold, step S103；When the temperature of terminal is less than or equal to first
During threshold value, step S104.
Concrete, after reducing charge power, then inquire the temperature of a terminal at regular intervals, it is judged that terminal
Whether temperature changes, if still above first threshold.
S103, continuation reduce charge power setting value.It is then back to step S102, continue the temperature of inquiry terminal.
When the temperature of terminal is still above first threshold, then continue to reduce charge power.Reduce the value (width of charge power
Degree) can set according to actual needs, reduce charge power 2W for example, it is possible to set.It is of course also possible to be set as 1W, 1.5W,
2.5W, 3W, 4W etc., do not limit at this.
S104, stopping reduce charge power.
When the temperature of terminal is less than or equal to first threshold, then illustrate that terminal has already decreased to suitable temperature, then no longer
Reduce charge power, terminate this power and reduce flow process.
Thus by gradually reducing charge power so that the temperature of terminal can be immediately lower than first threshold, prevents once
Property to reduce charge power too many, to keep very fast charging rate.
In further embodiments, the process that terminal reduces charge power is：Reduce in flow process at a power, when first

Degree, as long as temperature is more than lower limit still above first threshold and current charge power, then continues to reduce charge power, directly
It is less than or equal to first threshold or charge power to temperature less than or equal to lower limit.Here power reduce flow process with
It is identical that aforementioned power reduces flow process, is not repeated herein.
Terminal reduces the idiographic flow of charge power as shown in Figure 4, comprises the following steps：
S201, detect terminal temperature be more than first threshold, reduce charge power setting value.
This step S121 is to reduce charge power first in a power reduction flow process, reduces the value (amplitude) of charge power
Can set according to actual needs, reduce charge power 2W for example, it is possible to set.It is of course also possible to be set as 1W, 1.5W,
2.5W, 3W, 4W etc., do not limit at this.

The value of low charge power is unequal.For example, power reduces and reduces three charge powers in flow process, for the first time with the
The value that secondary reduces charge power differs, and the value that second time reduces charge power with third time is identical, fills as reduced for the first time
Electrical power 2W, second time and third time reduce charge power 1W every time.
Preferably, reduce in flow process at a power, when at least reducing charge power twice, be gradually reduced fall every time
The value of low charge power.For example, a power reduction flow process reduces three charge powers, reduce charge power for the first time
2W, second time reduces charge power 1.5W, and third time reduces charge power 1W.And for example, a power reduction flow process reduces
Four charge powers, reduce charge power 2W for the first time and for the second time every time, and third time reduces charge power 1.5W, for the third time fall
Low charge power 1W.So that regulation process is more steady, prevent accommodative excess from making charge power drop too low, and then
Affect charging rate.

The corresponding Second Threshold in the different position of terminal can be the same or different, and usual Second Threshold can be according to
One threshold value determines.It for example, it is possible to set first threshold and Second Threshold respectively as 37 DEG C and 35 DEG C, or it is 40 DEG C and 38
DEG C, etc..
S124, raising charge power.
Concrete, when temperature terminal being detected is less than Second Threshold, in order to improve charging rate, then improve charging work(
Rate.Concrete, the raising of charge power can be realized by increasing charging current or charging voltage.

S402, with Preset Time as cycle, timing detect terminal temperature.Judge the temperature of terminal whether still less than
Two threshold values, judge whether current charge power is less than higher limit simultaneously；When the temperature of terminal still less than Second Threshold and is worked as
When front charge power is less than higher limit, step S403；When the temperature of terminal is more than or equal to Second Threshold or charging
When power is more than or equal to higher limit, step S404.
Concrete, after improve charge power, then inquire the temperature of a terminal at regular intervals, it is judged that terminal

Electrical power.The value (amplitude) improving charge power can set according to actual needs, improves charge power for example, it is possible to set
2W.It is of course also possible to be set as 1W, 1.5W, 2.5W, 3W, 4W etc., do not limit at this.
S404, stopping reduce charge power.
When the temperature of terminal is more than or equal to Second Threshold or charge power more than or equal to higher limit, then explanation is eventually
End has reached suitable temperature ranges or charge power has reached higher limit, then no longer improve charge power, terminate this work(
Rate improves flow process.
Thus by setting charge power higher limit, it is therefore prevented that charge power is too high and affects charger.
Alternatively, improve in flow process at a power, when at least improve charge power twice, improve charging work(every time
The value of rate is all equal.For example, a power raising flow process improves three charge powers, improve charge power every time
Value is all 2W.
Alternatively, improve in flow process at power, when at least improve charge power twice, at least adjacent carry twice
The value of high charge power is unequal.For example, power improves and improves three charge powers in flow process, for the first time with the

In first threshold).
Thus, the charging method of the embodiment of the present invention, by the bigger intended application of monitoring caloric value in charging process
The use state of program, when detecting that destination application is in running status, start immediately to perform charge power relatively low the
One charging strategy, affects the experience of user to prevent terminal from seriously generating heat, when detecting that destination application is in not
During running status, then perform the second higher charging strategy of charge power, to ensure charging rate.It is achieved thereby that quickly filling
Electric process improves the experience of user, has taken into account charging rate and user's experience, improve user satisfaction, improve
The competitiveness of product.
Embodiment two
With reference to Fig. 8, proposing the charging device of second embodiment of the invention, described device includes monitoring modular 10 and processes mould
Block 20, wherein：
Monitoring modular 10：For in charging process, the running status of destination application in monitoring terminal.And will monitoring
Result notifies processing module.
Concrete, after detecting that the charging inlet of terminal and charger are connected entrance charged state, monitoring modular 10 is then
Start the running status of destination application in monitoring terminal.Described destination application can include talk application program, trip
Play application program, video application, navigation application program, camera application program etc. cause terminal heating serious answering when running
By the one in program or at least two.Further, user can as required, and any application program is appointed as target should
Use program.
It is alternatively possible to set two states, the respectively first state and the second state for destination application.Charged
Cheng Zhong, the state handover event of monitoring modular 10 monitoring objective application program；When destination application is switched to the first state,
Determine that destination application is in running status；When destination application is switched to the second state, determine destination application
It is in off-duty state.This monitoring mode, consumes energy low, and can detect the running status of destination application in real time.
For example：When destination application is talk application program, the definition state of answering is the first state, hangs up shape
State is the second state, can implant callback interface in talk application program, monitoring modular 10 by callback interface monitoring answer/
Hang up state switching generation, when monitor answer state when, determine that talk application program brings into operation, be in running status；
When monitor hang up state when, determine that talk application EP (end of program) runs, be in off-duty state.When destination application is trip
When play application program, video application, navigation application program or camera application program, definition starting state is the first state,
The state of exiting is the second state, can be in game application, video application, navigation application program and camera application program
Middle implantation callback interface, monitoring modular 10 starts/exits the generation of state switching by callback interface monitoring, when monitoring startup
During state, determine that aforementioned applications program brings into operation, be in running status；When monitor exit state when, determine aforementioned applications
EP (end of program) runs, and is in off-duty state.
It will be understood by those skilled in the art that can in the way of using other operation shape of monitoring objective application program
State.For example, monitoring modular 10 detects whether destination application is currently currently running in real time, but this mode consumes energy higher.
And for example, whether the detection destination application of monitoring modular 10 timing is currently currently running, but this mode real-time is poor, i.e.
The running status of destination application can not be detected timely.
Processing module 20：For when destination application is in running status, perform the first charging strategy, to reduce end
End heating；When destination application is in off-duty state, perform the second charging strategy to ensure charging rate.Wherein,
The two corresponding charge powers of charging strategy are more than the first corresponding charge power of charging strategy.
Concrete, when monitoring modular 10 monitor destination application be in running status when, processing module 20 then performs
The first relatively low charging strategy of charge power, to alleviate the problem that the terminal brought when destination application runs seriously is generated heat.
When monitoring modular 10 monitor destination application be in off-duty state when, it is higher that processing module 20 then performs charge power
Second charging strategy, at full speed charging, it is ensured that charging rate.
Alternatively, processing module 20 can take following first charging strategy：Directly limit charge power to make a reservation for first
Level, to reduce charge power, reduces caloric value.For example, it is assumed that normal charge power is 20W, at destination application
After running status, then limit charge power to 15W.
For different destination applications, its corresponding first predeterminated level can be the same or different, i.e. when not
When same destination application runs, charge power can be reduced to identical level or different levels by processing module 20.
Corresponding power level can be set according to experiment for different destination applications, for the high application program of caloric value, then
Set relatively low power level, otherwise then set higher power level.
Alternatively, processing module 20 may also take on following first charging strategy：The temperature of detection terminal, when the temperature of terminal
When degree is more than first threshold, just reduce charge power.Now, processing module is as it is shown in figure 9, include temperature detecting unit 21 and work(
Rate reduces unit 22, wherein：
Temperature detecting unit 21：For detecting the temperature of terminal.
Concrete temperature detecting unit 21 can real-time by temperature sensor or timing (periodically) detection terminal refer to
Determine the temperature at position.Described appointed part be typically to generate heat more serious or user to temperature than more sensitive position, certainly, it is possible to
To specify any part as required.
It is alternatively possible at positions such as the battery of terminal, screen, central processing unit, PMU, graphic process unit
In any one position temperature sensor is set, temperature detecting unit 21 detects any one portion aforementioned by temperature sensor
The temperature of position.
Alternatively it is also possible in portions such as the battery of terminal, screen, central processing unit, PMU, graphic process unit
At least two position in Wei arranges temperature sensor, and temperature detecting unit 21 detects aforementioned at least two by temperature sensor
The temperature at position.
It is possible to further specify different temperature detection positions for different destination applications.For example, when call should
When running by program, predominantly detect the temperature of screen, because screen contact face, the therefore temperature to screen when user makes a phone call
Most sensitive；Meanwhile, staff grips terminal bonnet area of cell, therefore can also detect the temperature of battery.And for example, when game application
When program or video application run, predominantly detect the temperature of central processing unit and/or graphic process unit, because playing and regarding
Frequency needs to consume the ample resources of central processing unit and graphic process unit, causes the two device heating amount big.
It will be understood by those skilled in the art that in addition to using temperature sensor and detecting the temperature of terminal, can also adopt
Detect the temperature of terminal with alternate manner of the prior art, be not repeated herein.
Power reduces unit 22：When the temperature of terminal is more than first threshold, reduce charge power.
In charging process, when the temperature of terminal exceedes certain value, user may feel that uncomfortable, affects user's body
Test, the temperature of terminal can be reduced by reducing charge power, make to this end, the embodiment of the present invention pre-sets first threshold
Higher limit for temperature.First threshold can determine with experimental result according to actual needs, for example, it is possible to set first threshold
It is 40 DEG C.
The corresponding first threshold in the different position of terminal can be the same or different.More sensitive to temperature for user
Position, first threshold can arrange lower, and user is not very sensitive position to temperature, and first threshold can be arranged
Obtain higher.For example, screen is the position that face directly contacts, more sensitive to temperature, therefore can be corresponding with setting screen
First threshold is 37 DEG C；And the positions such as battery center processor, PMU, graphic process unit, it is staff mediate contact
Position, higher to the tolerance level of temperature, therefore can set the corresponding first threshold in these positions as 40 DEG C.
Power reduces the size that unit 22 compares the temperature detecting and first threshold, when temperature is more than first threshold,
Then reduce charge power, specifically can realize the reduction of charge power by reducing charging current or charging voltage.
When have detected the temperature at terminal at least two position, as long as then the temperature at arbitrary position is more than first threshold, work(
Rate reduces unit 22 and then reduces charge power；Or, when the temperature at the position of terminal predetermined number is more than first threshold, power
Reduce unit 22 and just reduce charge power.Predetermined number can set as required, as being set as one, two, three etc., and example
As：When the temperature at one position of terminal is more than first threshold, and when the temperature at other positions is not more than first threshold, power reduces
Unit 22 does not then reduce charge power；When the temperature at two positions of terminal or plural position is more than first threshold,
Power reduces unit 22 and then reduces charge power.
In certain embodiments, power reduces unit 22 and reduces charge power in the following manner：Reduce at a power
In flow process, when detecting that the temperature of terminal is more than first threshold first, reduce charge power setting value；With Preset Time as week
Phase, detected the temperature of terminal by temperature detecting unit 21 timing；When the temperature of terminal is still above first threshold, continue fall
Low charge power setting value；When the temperature of terminal is less than or equal to first threshold, stop reducing charge power.Thus by by
Secondary reduction charge power so that the temperature of terminal can be immediately lower than first threshold, prevents disposably reducing charge power too many,
To keep very fast charging rate.
In further embodiments, power reduces unit 22 and reduces charge power in the following manner：Drop at a power
In low flow process, when detecting that the temperature of terminal is more than first threshold first, reduce charge power setting value；It with Preset Time is
In the cycle, detected the temperature of terminal by temperature detecting unit 21 timing；When the temperature of terminal is still above first threshold, and charging
When power is more than lower limit, continue to reduce charge power setting value；When the temperature of terminal is less than or equal to first threshold, or fill
When electrical power is less than or equal to lower limit, stop reducing charge power.Thus by setting charge power lower limit, it is therefore prevented that fill
Electrical power is too low and affects charging rate.
A foregoing power reduces flow process, reduces charge power i.e. first and reduces the whole of charge power to stopping
Process.
Alternatively, reducing in flow process at a power, when at least reducing charge power twice, power reduces unit 22
The value reducing charge power every time is all equal.For example, a power reduction flow process reduces three charge powers, every time
The value reducing charge power is all 2W.
Alternatively, reduce in flow process at a power, when power reduction unit 22 at least reduces charge power twice,
At least adjacent value reducing charge power twice is unequal.For example, a power reduction flow process reduces three chargings
Power, the value reducing charge power for the first time with second time differs, and the value that second time reduces charge power with third time is identical,
As reduced charge power 2W for the first time, second time and third time reduce charge power 1W every time.
Preferably, reducing in flow process at a power, when at least reducing charge power twice, power reduces unit 22
It is gradually reduced the value reducing charge power every time.For example, a power reduction flow process reduces three charge powers, for the first time
Reducing charge power 2W, second time reduces charge power 1.5W, and third time reduces charge power 1W.And for example, a power reduces
Reducing four charge powers in flow process, reducing charge power 2W for the first time and for the second time every time, third time reduces charge power
1.5W, third time reduces charge power 1W.So that regulation process is more steady, prevent accommodative excess from making the work(that charges
Rate drops too low, and then affects charging rate.
Further, processing module 20 also includes that a power improves unit 23, and this power improves unit 23 and is used for：Work as temperature
During less than Second Threshold, improving charge power, wherein first threshold is more than Second Threshold.
Second Threshold, as the lower limit of temperature, affects charging rate to prevent charge power from dropping too low, by inciting somebody to action
The temperature of terminal is maintained between first threshold and Second Threshold, both can guarantee that terminal temperature not Yin Taigao affects user's body
Test, can guarantee that again charge power does not reduces charging rate because of too low so that both charging rate and Consumer's Experience are taken into account.
The corresponding Second Threshold in the different position of terminal can be the same or different, and usual Second Threshold can be according to
One threshold value determines.It for example, it is possible to set first threshold and Second Threshold respectively as 37 DEG C and 35 DEG C, or it is 40 DEG C and 38
DEG C, etc..
When have detected the temperature at terminal at least two position, as long as then the temperature at arbitrary position is less than Second Threshold, work(
Rate improves unit 23 and then improves charge power；Or, when the temperature at the position of terminal predetermined number is less than Second Threshold, power
Improve unit 23 and just improve charge power.Predetermined number can set as required, as being set as one, two, three etc., and example
As：When the temperature at one position of terminal is less than Second Threshold, and when the temperature at other positions is not less than Second Threshold, then do not improve
Charge power；When the temperature at two positions of terminal or plural position is less than Second Threshold, then improve charge power.
Concrete, power improves unit 23 can realize the raising of charge power by increasing charging current or charging voltage.
In certain embodiments, power improves unit 23 and improves charge power in the following manner：Improve at a power
In flow process, when detecting that the temperature of terminal is less than Second Threshold first, improve charge power setting value；With Preset Time as week
Phase, detected the temperature of terminal by temperature detecting unit 21 timing；When the temperature of terminal is still less than Second Threshold, continue to carry
High charge set value of the power；When the temperature of terminal is more than or equal to Second Threshold, stop improving charge power.By gradually carrying
High charge power so that the temperature of terminal can fall into OK range smoothly, prevents temperature from rising and fall sharply and quickly, maintains charging
Stability.
In further embodiments, power improves unit 23 and improves charge power in the following manner：Carry at a power
In high flow process, when detecting that the temperature of terminal is less than Second Threshold first, improve charge power setting value；It with Preset Time is
In the cycle, detected the temperature of terminal by temperature detecting unit 21 timing；When the temperature of terminal is still less than Second Threshold, and charging
When power is less than higher limit, continue to improve the charge power setting value of terminal；When the temperature of terminal is more than or equal to Second Threshold,
Or when charge power is more than or equal to higher limit, stop improving charge power.By setting charge power higher limit, it is therefore prevented that
Charge power is too high and affects charger.
A foregoing power improves flow process, improves charge power i.e. first and improves the whole of charge power to stopping
Process.
Alternatively, improving in flow process at a power, when at least improve charge power twice, power improves unit 23
The value improving charge power every time is all equal.For example, a power raising flow process improves three charge powers, every time
The value improving charge power is all 2W.
Alternatively, improve in flow process at a power, when power raising unit 23 at least improves charge power twice,
At least adjacent value improving charge power twice is unequal.For example, a power raising flow process improves three chargings
Power, the value improving charge power for the first time with second time differs, and the value that second time improves charge power with third time is identical,
As improved charge power 2W for the first time, second time and third time improve charge power 1W every time.
Preferably, improving in flow process at a power, when at least improve charge power twice, power improves unit 23
It is gradually reduced the value improving charge power every time.For example, a power raising flow process improves three charge powers, for the first time
Improving charge power 2W, second time improves charge power 1.5W, and third time improves charge power 1W.And for example, a power improves
Improve four charge powers in flow process, improving charge power 2W for the first time and for the second time every time, third time improves charge power
1.5W, third time improves charge power 1W.So that regulation process is more steady, prevent accommodative excess from temperature is fallen
OK range outer (being higher than first threshold).
Alternatively, when processing module 20 performs the second charging strategy, charge power can directly be improved to the second predetermined water
Flat, charging at full speed, it is ensured that charging rate；Also can detect the temperature of terminal, as the temperature of terminal reduces, gradually step up charging
Power is to the second predeterminated level, to prevent instantaneous raising charge power from causing temperature to rise sharply.
The charging device of the embodiment of the present invention, by monitoring the bigger destination application of caloric value in charging process
