Certainly, in actual applications, the test point of the temperature of detection battery of mobile terminal can be arranged on Near battery module, improve the degree of accuracy of detection.
Preferably, step 110 includes:
Sub-step 112, by preset temperature detection resistance, detects the temperature of battery of mobile terminal in real time.
It is appreciated that in embodiments of the present invention, can be by arranging temperature detection the most in the terminal Resistance, detects the temperature of battery of mobile terminal in real time by the resistance of detection temperature detection resistance.
In actual applications, temperature detection resistance can be NTC (Negative Temperature CoeffiCient, negative temperature coefficient) critesistor.Fuselage outer side at mobile terminal arranges the inspection of this temperature Measuring resistance, arranges temperature detecting module the most in the terminal, and this temperature detecting module is with temperature detection Resistance constitutes a temperature sensing circuit, removes to detect the electricity of temperature detecting module by this temperature sensing circuit The change of resistance determines current temperature value.
Such as, for aforesaid NTC thermistor, the calculating function of its resistance value can be approximately formula (1):
R T = R T N × expB n ( 1 T - 1 T N ) ... formula (1)
Wherein, RT: during for temperature T DEG C, the resistance value of NTC thermistor；RTN: for specified During temperature TN DEG C, the resistance value of NTC thermistor；Bn: for the material constant of NTC thermistor, Also known as heat sensitive index；Exp: for the index (e=2.71828 ...) with natural number as the end.
In conjunction with voltage equation U=IR, temperature detecting module adds same electricity at NTC thermistor two ends Pressure U, the electric current I in testing circuit, then be calculated the critesistor of current NTC according to voltage equation Resistance value be R=U/I, due to R in formula (1)TN、Bn, TN be known quantity, then again will RT=R=U/I substitutes in formula (1), can calculate the value of current temperature T of mobile terminal.

Preferably, above-mentioned first application is specified to include running current the answering more than first threshold of demand With.First specifies application include calling the application of flash lamp and/or call the application of radio-frequency module and/or big Type game application.
In embodiments of the present invention, above-mentioned first appointment application is the normal of the demand when enabling or work Operating current is more than the application of first threshold, it is understood that for needing the application of big operating current.First Specify application can include calling the application of flash lamp and/or calling application and/or the big game of radio-frequency module Application.Such as mobile phone, the above-mentioned application calling flash lamp includes that various video camera is applied: above-mentioned tune Including talk application with the application of radio-frequency module, this talk application i.e. takes the application of phone, above-mentioned large-scale Game application is interpreted as CPU's and/or GPU (Graphics Processing Unit, graphic process unit) Use the frequency game application more than Second Threshold.If user is fitted without game application certainly, then may be used Not include above-mentioned application.The most such as panel computer, typically no radio-frequency module, the present invention implements Can not also include the application calling radio-frequency module in example, panel computer generally individually includes photographic head, then originally Inventive embodiments then can include the application calling photographic head, if the application of user installation big game, also Can include that big game is applied.
Certainly, the embodiment of the present invention may also include other application needing big operating current, and the present invention is the most right It is any limitation as.
Wherein, if described first appointment application is the application calling flash lamp, then step 120 includes:
Sub-step 124, according to the temperature of described battery of mobile terminal, when application call flash lamp, controls Flash lamp drives the operating current of output.
As a example by mobile phone, if opening flash lamp while mobile phone photograph, by default, mobile phone work Make electric current for electric current of taking pictures (500mA)+flash lamp main lightning stream (700mA), now peak of battery-end Value electric current is 1200mA.This current value is very big, if the internal resistance of cell increases when low temperature, meeting moment is electricity Pond output voltage drags down, and causes mobile phone automatic shutdown.
And the embodiment of the present invention, can be by the main lightning stream of flash lamp when low temperature, such as less than 0 DEG C, Main lightning stream is set to 100mA, then it is electric current of taking pictures (500mA) that mobile phone controls the electric current being of taking pictures + flash lamp main lightning stream (100mA), now the peak point current of battery-end is 600mA, and ratio is higher than 0 DEG C Time acquiescence electric current 1200mA much lower, greatly reduce cell voltage drag down appearance from The probability of dynamic shutdown.
In actual applications, mobile phone click on take pictures time, by CPU (Central Processing Unit, Central processing unit) controlling to glisten drives the electric current of output 100mA, and wherein, camera function is set to Enable flash lamp.Wherein, above-mentioned flash lamp drives and refers mainly to flash lamp operation control IC (integratedcircuit, integrated circuit), it is provided that the voltage of flash lamp operation, electric current, is entered by CPU Row controls.In embodiments of the present invention, for different temperature, it is provided with the flash of light of different operating electric current Lamp parameter, at a temperature of certain, directly invokes the Flashing Light Parameters of relevant temperature when enabling flash lamp, control Flash lamp processed drives and exports corresponding operating current.
Wherein, if described first appointment application is the application calling radio-frequency module, then step 120 includes:
Sub-step 124, according to the temperature of described battery of mobile terminal, when application call radio-frequency module, control The operating current of radio-frequency module processed and/or reduction mobile terminal display screen brightness and/or pass closed call are penetrated Other application being currently running outside the application of frequency module.
As a example by mobile phone, when mobile phone receives speech signal, when i.e. answering the call, its radio frequency mould to be called Block amplifies speech signal, if in the case of room temperature, also makes radio-frequency module use the operating current given tacit consent to defeated Deliver to；If in the case of low temperature, then control the radio-frequency module operating current from acquiescence, will be low for this The operating current that temperature is corresponding.When mobile phone sends speech signal, when i.e. making a phone call, if in room temperature situation Under, its radio-frequency module to be called amplifies speech signal, also makes radio-frequency module use the operating current of acquiescence； If in the case of low temperature, then control the radio-frequency module operating current from acquiescence, will be corresponding for this low temperature Operating current.
Certainly, the radio-frequency module operating current from acquiescence is being controlled, by the operating current corresponding for this low temperature Time, it is also possible to the operating current of other modules of mobile phone is changed, and such as reduces the bright of mobile phone display screen Degree, because brightness of display screen is the lowest, the operating current of display screen demand is the lowest, such that it is able to indirectly control The operating current of mobile terminal is within trouble free service electric current；The most such as close the application of closed call radio-frequency module Outside other application being currently running, the such as current game application run, because these application run Can take some system resources, the such as resource such as CPU and/or GPU, internal memory, it is also required to certain electricity Stream, then after closing above-mentioned application, it is possible to reduce the operating current of mobile terminal, such that it is able to indirectly Control the operating current of mobile terminal within trouble free service electric current.
Certainly, in the case of room temperature, such as more than 0 DEG C, do not reduce the operating current of any application, allow It runs according to the operating current of acquiescence, it is possible to do not close any application being currently running.
Certainly, in actual applications, radio-frequency module is in order to ensure speech quality, at low temperatures, and can Not change its acquiescence operating current, and the operating current of other modules of mobile phone is changed, such as Reduce the brightness of mobile phone display screen.And/or other are currently running outside closing the application of closed call radio-frequency module Application, such as closes wechat application, qq application, music application, browser application, game application etc..
Wherein, if described first appointment application is big game application, then step 120 includes:
Sub-step 128, according to the temperature of described battery of mobile terminal, when big game application enables, Reduce CPU and the frequency of/GPU and/or reduce mobile terminal display screen brightness.And/or close described Other application being currently running outside big game application, such as close wechat application, qq application, browse Device application, music application etc..
Because big game applies normal startup can take higher CPU and GPU, then in low tender feeling Under condition, when mobile terminal enables big game application, the frequency of CPU and GPU can be reduced so that it is Run with relatively slow or lower quality, thus reduce the operating current of mobile terminal, such that it is able to indirectly control The operating current of mobile terminal processed is within trouble free service electric current.And/or, reduce mobile terminal display screen Brightness, it is possible to reduce the operating current of mobile terminal.And/or close described big game application outside other The application being currently running.
And in the case of room temperature, also can enable big game application according to default situations.
The embodiment of the present invention is by detecting the temperature of mobile terminal itself, thus according to said temperature, controls Mobile terminal, when enabling the first appointment application, selects trouble free service electric current corresponding with said temperature to transport OK.Therefore, the embodiment of the present invention is from the aspect of software, and control mobile phone is when enabling some application, not Operating current under synthermal, makes the output voltage of the lithium ion battery of mobile phone be higher than the minimum of handset demand Voltage, thus reduce because unexpected big electric current causes the output voltage of lithium ion battery less than handset demand Minimum voltage, and cause the probability of mobile terminal automatic shutdown.
