When the temperature data, which is less than, limits T2 at this temperature, the battery charge controller judges corresponding temperature sensor
The operational module closed on currently generates heat relatively low.The higher work of generating heat that temperature sensor closes on may now be changed
Module has been stopped, and nearby environment temperature gradually reduces for this position.
When the temperature data (is less than or equal to temperature upper limit T1 between temperature upper limit T1 and lowest temperature T2
And be more than or equal to lowest temperature T2) between when, the battery charge controller judges that corresponding temperature sensor closes on
Operational module currently heating is normal.
S306, the charging current of each charging module is controlled according to the heat condition judged.
Specifically, the control charging current includes rise charging current, reduces charging current and maintain original to fill
Electric current.
As shown in fig.4, the first particular flow sheet for step S306 in Fig. 3.
S406, when currently heating is higher for the operational module that the temperature sensor closes on, control corresponding charge
Module reduces charging current, until the charging module is stopped.
In the present embodiment, the charging module can be controlled to reduce charging current according to the height of the temperature data
Degree.For example, when difference of the temperature data more than temperature upper limit T1 is 1 DEG C, control is corresponding to fill
The charging current of electric module reduces 25mA.Alternatively, it is also possible to control charging module reduction according to predetermined ratio
The degree of charging current.For example, when the temperature data is more than temperature upper limit T1, control to inductive charging mould
The charging current of block reduces by 50%.
S408, when currently heating is higher for the operational module that the temperature sensor closes on, control corresponding charge
Module is started working or rise charging current.
In the present embodiment, the charging module can be controlled to raise charging current according to the height of the temperature data
Degree.For example, when the difference that the temperature data is less than limit T2 at this temperature is 1 DEG C, control is corresponding to fill
The charging current rise 25mA of electric module.Alternatively, it is also possible to control the charging module to raise according to predetermined ratio
The degree of charging current.For example, when the temperature data is less than and limits T2 at this temperature, control to inductive charging mould
The charging current rise 50% of block.
S410, when the operational module that the temperature sensor closes on currently generates heat normal, control corresponding charge
Module maintains former charging current, that is, continues to charge to battery by original charging current.
It is appreciated that in other embodiments, the predetermined threshold value can also include multiple temperature upper limits and more
Individual lowest temperature, the battery charge controller is according under the temperature data and the plurality of temperature upper limit and multiple temperature
Limit judges the heat condition around corresponding temperature sensor.Now the heat condition can be sub-divided into multiple
Stage.Then the charging current of each charging module is controlled according to the heat condition in the plurality of stage.
For example, the predetermined threshold value can also include temperature upper limit T3, T4 and lowest temperature T5, T6, its
Middle T3 ＞ T4 ＞ T5 ＞ T6.When the temperature data is more than temperature upper limit T3, the battery charge controller is sentenced
Currently heating is very high for the operational module that disconnected corresponding temperature sensor closes on, directly charging module corresponding to control
It is stopped.
When the temperature data is between temperature upper limit T3 and T4, the battery charge controller judges corresponding

Maintain former charging current.
When the temperature data is between limit T5 and T6 at this temperature, the battery charge controller judges corresponding
The operational module that temperature sensor closes on currently generates heat than relatively low, the charging current of charging module corresponding to control
Rise 50%.
When the temperature data, which is less than, limits T6 at this temperature, the battery charge controller judges corresponding temperature sensor
Currently heating is very low for the operational module closed on, the charging current rise 100% of charging module corresponding to control.
The charge control method that the present embodiment proposes, can be according to the real-time temperature of each position in the terminal device
Degree situation dynamically controls the charging process of the terminal device, and corresponding charging module is reduced when temperature raises
Charging current raises the charging current of corresponding charging module when temperature reduces to reduce charging module heating
To recover to charge normal so that the terminal device is not in the too high situation of local temperature while charging.
As shown in fig.5, second of particular flow sheet for step S306 in Fig. 3.In the present embodiment,
Step S506-S510 and the step S406-S410 in Fig. 4 are similar, and difference is that the present embodiment also includes step
Rapid S512.
S506, when currently heating is higher for the operational module that the temperature sensor closes on, control corresponding charge
Module reduces charging current, until the charging module is stopped.
S508, when currently heating is higher for the operational module that the temperature sensor closes on, control corresponding charge
Module is started working or rise charging current.
S510, when the operational module that the temperature sensor closes on currently generates heat normal, control corresponding charge
Module maintains former charging current, that is, continues to charge to battery by original charging current.
S512, after part charging module (being referred to as target charging module) reduces or raises charging current, control
Make other charging modules to compensate the reduction or rise charging current so that the total bulk charging of the terminal device
Electric current maintains former specified state.
For example, working as has a target charging module that charging current is reduced into 50mA because the temperature of surrounding is higher
When, the charging module that the battery charge controller controls another environment temperature relatively low raises charging current
50mA；Or the charging module for controlling another environment temperature relatively low and not working currently is started working, charging
Electric current is 50mA；Or the charging module rise charging current that one group of environment temperature of control is relatively low, group charging
The elevated charging current summation of module is 50mA.
In the present embodiment, the battery charge controller can control another or one group of charging module to target
Charging module reduces or elevated charging current compensates.When one group of charging module of control is to the reduction or liter
, can be with the charging current of mean allocation compensation when high charging current compensates, can also be according in the group
Each charging module is pressed with conditions such as the temperature datas around the distance of target charging module or each charging module
According to the charging current of predetermined ratio distribution of compensation.
For example, when have a charging module A because the temperature of surrounding is higher and by charging current reduce 60mA when,
The battery charge controller controls the relatively low charging module rise charging current of one group of environment temperature.Assuming that the group is filled
Electric module includes two charging modules B and C, wherein, charging module B and charging module A distance compared with
Closely, and charging module C and charging module A it is distant.The battery charge controller controls charging module
Charging current is raised 20mA by B, and charging current is raised 40mA by control charging module C.Or, it is assumed that
Temperature around charging module B is higher than the temperature around charging module C, battery charge controller control control
Charging current is raised 20mA by charging module B, and charging current is raised 40mA by control charging module C.
It is appreciated that in other embodiments, the battery charge controller can also be according to setting and the present situation
Other rational concrete modes are taken to make the terminal device totality charging current maintain former specified state.
The charge control method that the present embodiment proposes, it can be mended by electric current mutual between multiple charging modules
Repay, keep the overall charging current of the terminal device to maintain former specified state, so as to avoid influenceing the terminal
The charging rate of equipment.
In one alternate embodiment, specific data can be combined, are said for the overall flow of this method
It is bright.Fig. 6 show in the alternative embodiment corresponding relation curve between temperature data and charging current.Its
Middle transverse axis represents charging current (unit：MA), vertical pivot represents temperature data (unit：℃).This method
Flow comprises the following steps：
When monitoring charging inlet connection above charger, start charging control function.It is assumed that the mould that each charges
The setting charging current of block is 1000mA, and three charging modules have been used in whole terminal device.It is now each
Charging module starts to be filled with the electric energy inputted on charger conversion output to set charging current 1000mA
Onto battery, each temperature sensor starts the temperature data around the corresponding charging module of monitoring in real time, concurrently
Give the battery charge controller.
Temperature T around the first charging module is monitored to more than the first temperature upper limit T4, but less than second
(T4 during temperature upper limit T3<T<T3), the charging current of first charging module is reduced by 50%, i.e., only carried
For 500mA charging current.Then if other two charging module environment temperatures are not above the first temperature
Upper limit T4, the 500mA charging currents at this moment reducing the first charging module, is evenly distributed to other two and fills
In electric module.So, the charging current of the first charging module is 500mA, and the second charging module and the 3rd fills
The charging current of electric module is 1250mA.
After Fixed Time Interval t, continue to monitor the temperature around each charging module.If the first charging
Temperature T around module continues to rise, and exceedes second temperature upper limit T3 (T>T3), now control should
First charging module is stopped.Then if other two charging module environment temperatures are still not above the
One temperature upper limit T4, then the 500mA charging currents that the first charging module reduces are redistributed to other two and filled
In electric module.I.e. now the charging current of the second charging module and the 3rd charging module is 1500mA.
Then proceed to monitor the temperature around each charging module every time interval t.So constantly monitor and right
Charging current is reallocated.Until the charging current on some charging module reaches its maximum that can be supported
After charging current, it is not further added by.Now the heat condition of whole terminal device is than more serious, so subtracting
Fall part charging current to reduce the risk of complete machine overheat.
If on the contrary, now monitor that the temperature T around the first charging module is less than the first lowest temperature T5,
But it is more than second temperature lower limit T6 (T6<T<T5), by increased charging is electric before on other two charging modules
The 50% of summation is flowed, is increased to again on the first charging module.That is the now charging current of the first charging module
For 500mA, the charging current of the second charging module and the 3rd charging module is 1250mA.
Then proceed to monitor the temperature around each charging module after Fixed Time Interval t.When monitoring first
(T when temperature T around charging module is less than second temperature lower limit T6<T6), by other two charging modules
Increased charging current all increases on first charging module again before upper.I.e. now three charging moulds
The charging current of block is 1000mA, returns to the state of original charge.
The overall flow of one alternative embodiment of this method is said in conjunction with concrete application scene below
It is bright.
User charges normal a terminal device (such as mobile phone), and the battery charge controller of the mobile phone, which starts, to be filled
Electric control function.Each charging module, which starts to change the electric energy inputted on charger with setting electric current, to be exported
It is filled on battery, each temperature sensor starts the temperature data around the corresponding charging module of monitoring in real time,
And it is sent to the battery charge controller.Now the temperature around each charging module of the mobile phone substantially all in
, can be with normal work below predetermined threshold value.
And certain a period of time user browses webpage using the wireless networking capabilities of the mobile phone, at this moment the mobile phone is penetrated

Heating, and drive module ambient temperature to gradually step up together.At this moment the temperature of the radiofrequency emitting module is closed on
This temperature data is sent to battery charge controller by degree sensor.Battery charge controller controls the radio-frequency transmissions mould
Charging module near block gradually reduces charging current, should until closing to reduce the heating of the charging module
Charging module.Temperature is experienced in the outside of so mobile phone, would not be because of the radiofrequency emitting module and the charging
Module works simultaneously and local temperature is too high.
Meanwhile battery charge controller will be far from the charging currents of other charging modules of the radiofrequency emitting module and fit
Work as rise, keep overall charging current not reduce, maintain former specified state so that the charging speed of the mobile phone
Spend unaffected.
After user stops using the mobile phone to browse webpage, the radiofrequency emitting module is stopped, surrounding environment
Temperature gradually reduces.Feedback of status that the temperature sensor of the radiofrequency emitting module reduces temperature is closed on to filling
Controller for electric consumption.The battery charge controller steps up the charging module near the radiofrequency emitting module immediately
Charging current is to normal charging condition.The charging of other charging modules of the radiofrequency emitting module is will be far from simultaneously
Current synchronization reduces, and still keeps overall charging current constant.
Therefore, the battery charge controller can dynamically control the charging of the mobile phone according to real time temperature situation
Journey so that the mobile phone is not in the too high situation of local temperature.At the same time it can also pass through multiple charging moulds
Mutual current compensation between block, the overall charging current of the mobile phone is kept to maintain former specified state, to keep away
Exempt to influence the charging rate of the mobile phone.
