Specific embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that specific embodiment described herein is only to explain the present invention, and without
It is of the invention in limiting.
Fig. 3 is referred to, Fig. 3 is the flow chart of the method preferred embodiment of the setting cell output voltage that the present invention is provided,
Including step：
S100, the instruction by receiving setting cell voltage, obtain the first cell voltage to be placed；
When being embodied as, corresponding menu can be provided on a user interface and to be placed the is input into for mobile terminal developer
One cell voltage.
Further, starting before the first cell voltage is set, i.e., should also include before step S200：
S000, judge that cell voltage is whether full, if discontented, point out the developer will by mobile terminal is connected charger
Battery is fully charged；
Because if cell voltage is less than the first cell voltage to be placed, then battery cannot export the first battery electricity to be placed
Pressure, and when cell voltage is higher than the first cell voltage to be placed, battery electricity can be made by improving battery discharge current
Pressure drop is low；Fig. 4 is specifically referred to, Fig. 4 show 20 structural representation of true battery, mainly include the internal resistance of cell in battery body
Rb and battery deposit energy Eb, if cell output voltage（Voltage difference between anode and negative pole）For Vb, cell output current is
Ib, then Vb=Eb-Ib*Rb（Formula 1）
Therefore it can be seen that so that cell output voltage Vb declines by only need to expand cell output current from formula 1；This
Bright subsequent step is exactly by constantly lifting slightly Ib, making Vb drop to gradually the first cell voltage to be placed.
Whether S200, detection current battery level, judge the current battery level more than first cell voltage, if
It is yes, then into step S300；
In this step, only current battery level is not less than the first described cell voltage, could meet the described in exporting
The condition of one cell voltage.
If discontented, developer is pointed out to lead to due to before step S200 it is determined that whether current battery level is full
Crossing will be mobile terminal connection charger fully charged by battery, therefore here detection, primarily to detection is full of in cell voltage
In the case of electricity, see whether current battery level meets the condition not less than the first cell voltage to be placed, if being unsatisfactory for,
Need further to process, such as take and install battery additional or change the measures such as battery, current battery level is met not less than setting
The first cell voltage condition.For example, the first cell voltage such as to be placed is 5.5V, if current battery level
It is only capable of providing the voltage of 5V in the case of fully charged, it is clear that the condition of the first cell voltage to be placed can not be met, now
Needs are taken and install battery additional or change the measures such as battery, enable the voltage that current battery level is provided to be higher than the first battery to be placed
Voltage.
Meeting the current battery level not less than under conditions of first cell voltage, according to testing result, from
And perform next step action, i.e., into step S300 or S400, i.e., when the current battery level is more than first battery electricity
During pressure, then star t-up discharge is controlled into step S300, when the current battery level is equal to first cell voltage, then enter
Enter step S400.
S300, discharge current is lifted by step value of the first discharge current for pre-setting, control star t-up discharge, return afterwards
Return step S200；
According to the result detected in step S200, when the current battery level is more than first cell voltage, then control is needed
Star t-up discharge processed, until making current battery level be reduced to equal to first cell voltage, so as to meet the first battery of output
The condition of voltage.
In this preferred embodiment, discharge current is lifted as step value with the first discharge current for pre-setting, control is opened
It is dynamic to discharge to make current battery level be reduced to first cell voltage.Therefore the first described electric discharge electricity need to be pre-set
Stream, it is preferred that the first described discharge current preferably takes 20 milliamperes.When as step value the first discharge current choosing it is enough
When little or suitable enough, the result discharged in this step would not produce the situation less than first cell voltage, therefore
In specific implementation process, the practical situation calculating and setting one according to current battery level and first cell voltage is needed
The first proper or sufficiently small discharge current, otherwise may result in the situation that repetition needs to charge.
If S400, current battery level are equal to first cell voltage, setting completed for cell voltage.
If the current battery level is detected equal to first cell voltage, just meet the bar of output voltage
Part, then setting completed for cell voltage.
The present invention is by detecting current battery level, and works as the current battery level more than first cell voltage
When, control star t-up discharge directly arbitrarily arranges battery by true battery till cell voltage is adjusted to the first cell voltage
Output voltage, so as to avoid needing while using DC source inconvenient to carry, and save again using what false battery brought
The cost of false battery is made, is the exploitation provides convenient of the battery correlation function of mobile terminal, raising efficiency.
