Cheng Wei：
Determine I2With I1Difference absolute value delta I=| I2-I1|、Ua2With Ua1Difference absolute value delta Ua=| Ua2-Ua1| with
And Ub2With Ub1Difference absolute value delta Ub=| Ub2-Ub1|；
By Δ UaWith Δ UbIt is compared, determines Δ UaWith Δ UbSize；
As Δ UaMore than Δ UbWhen, determine path resistance R=| Ua2-Ua1|/Δ I, or determine path resistance R=| Ub2-
Ub1|/ΔI+R1；
As Δ UaLess than Δ UbWhen, determine path resistance R=| Ub2-Ub1|/Δ I, or determine path resistance R=| Ua2-
Ua1|/ΔI+R1。
Specially：Calculate the corresponding second current value I of the second moment first resistor2It is corresponding with the first moment first resistor

The third voltage value U of first enda2With the first voltage value U of the first moment first resistor first enda1Difference absolute value, obtain
To voltage change Δ Ua=| Ua2-Ua1|；It is also required to calculate the 4th magnitude of voltage U at second the second end of moment first resistor simultaneouslyb2
With the second voltage value U at first the second end of moment first resistorb1Difference absolute value, obtain voltage change Δ Ub=| Ub2-
Ub1|。
Obtaining Δ Ua=| Ua2-Ua1| and Δ Ub=| Ub2-Ub1| afterwards, it is necessary to by Δ UaWith Δ UbIt is compared, it is determined that
ΔUaWith Δ UbSize.
In embodiments of the present invention, power supply, path internal resistance, first resistor are arranged in order, as Δ UaMore than Δ UbWhen, it is determined that
Now the first end of first resistor is connected with path internal resistance, now path resistance R=| Ua2-Ua1|/ΔI；Or can determine to lead to
Roadlock value R=| Ub2-Ub1|/ΔI+R1.As Δ UaLess than Δ UbWhen, it is determined that now the second end of first resistor connects with path internal resistance

Determine after path resistance, perform step 102.
Step 102, determine that according to path resistance mobile terminal safety works corresponding current value, and obtain mobile terminal to work as
Preceding real work current value.
When wherein determining the mobile terminal safety corresponding current value of work：Calculate supply voltage and mobile terminal normal work
Minimum voltage difference, mobile terminal carries out normal work in predeterminated voltage is interval；Calculate gained difference and path resistance
Ratio, result of calculation is defined as mobile terminal safety and worked corresponding current value.

Move the corresponding current value of terminal security work.When obtaining the mobile terminal safety corresponding current value of work, it is also desirable to utilize inspection
Slowdown monitoring circuit obtains the real work current value that mobile terminal is current.
For example：The supply voltage of lithium ion battery is Vocv, the internal resistance of power supply supply access for R (including battery it is equivalent in
Including resistance), it is ensured that the minimum voltage of mobile terminal normal work is Vbat1, and the real work electric current of mobile terminal is Ibat, that
It can determine：Mobile terminal real work voltage is that output voltage is Vbat=Vocv-Ibat*R；Then in Vocv-Ibat*R
During >=Vbat1, mobile terminal just can normal work, otherwise mobile terminal automatic shutdown or will restart.In the implementation case,
Work corresponding current value of mobile terminal safety is：(Vocv-Vbat1)/R；In Ibat≤(Vocv-Vbat1)/R, you can
Ensure mobile terminal normal work.Obtaining the corresponding current value of mobile terminal safety work and the current reality of mobile terminal
After working current value, step 103 is performed.

When the difference of the corresponding current value of terminal security work and real work current value is less than predetermined threshold value, turning-off mobile terminal is current
The process of an at least application program of operation is：When the corresponding current value of mobile terminal safety work and real work current value
When difference is less than predetermined threshold value, the application program to the current operation of mobile terminal is arranged according to the order of priority from high to low
Sequence；After the completion of sequence, turning-off mobile terminal currently sorts the application program of most end.
When the difference of the corresponding current value of mobile terminal safety work and real work current value is less than predetermined threshold value, press
According to default priority, the application program to the current operation of mobile terminal carries out the sequence of priority from high to low, moved closing
During at least application program that dynamic terminal is currently run, in the application program currently run, the minimum application of priority is determined
Program is closed.
For example：The application program of current mobile terminal operation includes application program of taking pictures, and carrying out flash lamp in user takes pictures
When, when having detected incoming call incoming call, if the difference of the corresponding current value of now mobile terminal safety work and real work current value
Value is less than predetermined threshold value, then needs to close an at least application program.And the priority for application program of taking pictures is less than incoming call application journey
The priority of sequence, now needs to take pictures by closing flash lamp to reduce the real work current value that mobile terminal is current, it is to avoid
The problem of there is mobile terminal automatic shutdown or restart.
It should be noted that this method also includes：
After the application program of sequence most end is closed, corresponding current value and real work if mobile terminal safety works
The difference of current value then needs to close the application program of sequence most end under current state still less than predetermined threshold value, until mobile whole
The difference of the corresponding current value of trouble free service and real work current value is held to be more than or equal to predetermined threshold value.
It is less than default threshold in the difference for detecting the corresponding current value of mobile terminal safety work and real work current value
Value, and close after the minimum application program of priority, because mobile terminal safety works corresponding current value for determination value, this
When mobile terminal real work current value change, it is necessary to continue to detect real work current value, if this time shift
Dynamic terminal security work corresponding current value with the difference of real work current value still less than predetermined threshold value, it is necessary in current state
The lower application program for determining that priority is minimum is closed, corresponding current value and real work until mobile terminal safety works
The difference of current value is more than or equal to predetermined threshold value.Wherein here the value of predetermined threshold value can be 0.1A or other numbers
Value a, or range intervals, those skilled in the art can set according to practical situation.
