Embodiment
The invention provides a kind of method and system that portable terminal when charging shows battery electric quantity of controlling, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1, Fig. 1 is that the present invention controls the schematic flow sheet that shows the method preferred embodiment of battery electric quantity when portable terminal charges, and as shown in the figure, comprises step:
S101, when detecting that charger inserts portable terminal and the battery of portable terminal charged, detect the internal resistance of cell R of described battery
INNER
The internal resistance of cell R of S102, the predetermined charging current of basis and acquisition
INNERObtain the standard charging current I of described charger
FINAL, and the charging current of described charger is set to described standard charging current I
FINAL
S103, the primary voltage of battery is increased by one revise voltage V
DELTAObtain the virtual voltage of battery, obtain battery electric quantity by described virtual voltage, and control the battery electric quantity that described portable terminal demonstration obtains.
In step S101, whether at first detect charger is inserted in the portable terminal and carries out charging operations, when detecting that charger is inserted into portable terminal and the battery of portable terminal charged, just begin to detect the internal resistance of cell of battery of mobile terminal, although generally can demarcate the internal resistance of cell on the battery, but along with the increase of battery access times, internal resistance of cell R
INNERCan constantly become large, so need to again demarcate internal resistance of cell R
INNER
Specifically, as shown in Figure 2, the idiographic flow of demarcating the internal resistance of cell comprises step:
S201, when detecting that charger inserts portable terminal and the battery of portable terminal charged, arrange at least two less than the measuring current of the described predetermined charging current charging current as charger; Should predetermined charging current arrange according to existing charger maximum output current, generally all more than 500mA, popular big screen intelligent portable terminal is full of electricity in setting time to the maximum output current that existing charger allows to satisfy at present.And if the charging current of charger is set to the electric current less than predetermined charging current, the electric current of the actual output of charger is the electric current of setting so.Take the charger of a 5V500mA as example, this charger maximum output current i.e. predetermined charging current 500mA, be 200mA when software arranges charging current, the output current of charger reality is 200mA so, certainly the charging current that arranges also can be predetermined charging current, but can not be greater than predetermined charging current.
S202, detect corresponding test voltage when according to described measuring current battery being charged; After being provided with at least two measuring currents, the test voltage that obtains in the time of can detecting by this measuring current charging, for example take the charger of above-mentioned 5V500mA as example, when measuring current being set being 400mA, by the ADC(analog to digital converter) detect cell voltage V
ADC400MA, when measuring current being set being 500mA, detect cell voltage V by ADC
ADC500MA
S203, obtain internal resistance of cell R by described at least two measuring currents and corresponding test voltage
INNER
Because measuring current is less than predetermined charging current, output current also is measuring current, and so last cell voltage also should be proportional relation, and its specific formula for calculation is as follows:
I wherein
Sw400MABe 400mA, V
OCCell voltage when uncharged.
Obtain at last
Wherein, V
ADC500MA, V
ADC400MAAll record, can calculate internal resistance of cell R by following formula
INNER
In step S102, by the internal resistance of cell R that obtains
INNERAnd predetermined charging current is obtained the standard charging current I of described charger
FINAL, and the size of the charging current of described charger is set to described standard charging current I
FINAL
Specifically, as shown in Figure 3, step S102 can be refined as following steps:
The charging current of S301, charger is set to described predetermined charging current, obtains corresponding cell voltage;
S302, the charging current of charger is increased 100mA, obtain the corresponding cell voltage that increases behind the electric current;
Whether the cell voltage that S303, judgement increase behind the electric current increases 100mA*R than the cell voltage before the increase electric current
INNER
Charging current corresponding to S304, the cell voltage before will increasing when no returned step S303 as the standard charging current of charger when being.
The core of above-mentioned steps is take predetermined charging current as benchmark, increases charging current on the basis of predetermined charging current, judges whether detect the cell voltage that obtains increases N*100mA*R
INNER, wherein N is the number of times of increase, thus the standard charging current that detects charger is maximum output current.
Charger take maximum output current as 600mA is example, and it is 500mA that charging current at first is set, and the cell voltage that detect by ADC this moment is V
ADC500MA, then increasing 100mA on the basis of 500mA, the charging current that arranges so is 600mA, because the charger that inserts is the charger of 600mA, so the charging current of the exportable 600mA of charger this moment, the cell voltage that detect by ADC this moment is V
ADC600MA, obtain V
ADC600MAWith V
ADC500MADifference
, should
Continuing to increase charging current is 700mA, detects the cell voltage V that obtains
ADC700MA, obtain V
ADC700MAWith V
ADC500MADifference
, because charger can't be exported the charging current of 700mA, so
So, can know that 600mA is the standard output electric current of charger.
After having obtained the standard output electric current of charger, charging current that can charger is set to this standard output electric current, thereby shortens the duration of charging in safe range.
In step S103, voltage V is revised in the primary voltage increase by of battery
DELTAObtain the virtual voltage of battery, described correction voltage V
DELTA=(I
FINAL-I
SW) * R
INNER, wherein, I
SWOriginal charging current for portable terminal is set obtains battery electric quantity by described virtual voltage, and controls the battery electric quantity that described portable terminal demonstration obtains.
In this step, although with the charging current setting of the charger standard charging current for charger, but the software of portable terminal can't calculate cell voltage with this standard charging current, so the information of the last battery electric quantity that obtains is also forbidden, need to revise cell voltage.
Specifically can increase by one on the basis of primary voltage and revise voltage, this primary voltage is the cell voltage that calculates according to the original charging current that portable terminal is set, for example certain standard charging current is that the charger of 800mA is inserted into when charging in the portable terminal, and portable terminal can calculate primary voltage according to the electric current of default 200mA.
Computing method are as follows:
Wherein, internal resistance of cell R
INNERCan calculate by step S101, here with R
INNER=150Ohm is example, I
FINALBe the standard charging current of charger, can obtain I by step S102
FINAL=800mA, so V
DELTA=600mA*150Ohm=90mv.The correction voltage that will obtain again adds that primary voltage obtains last cell voltage, obtains battery electric quantity according to this cell voltage.

| Electric weight | 42% | 50% | 56% | 62% | 68% | 76% | 77% | 83% | 88% | 92% | 100% |
And after revising, the cell voltage that calculates according to 800mA and the mapping table of battery electric quantity:
| Voltage | 3.390 | 3.490 | 3.669 | 3.687 | 3.716 | 3.740 | 3.767 | 3.788 | 3.790 | 3.800 | 3.809 |
