For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Main thought of the present invention is, on the basis that existing mobile device battery electric quantity detects, whether is in holding state judges mobile device.If it is in non-standby state, so certain process is made to the consumption of battery electric quantity, be specially: under non-standby state, when reading certain time cell voltage, battery electric quantity is deducted a particular value, the acquisition of this particular value is through and experimental results demonstrate, specifically by timer, discharge current when detecting battery electric quantity and detect number of times and determine.The detection of battery electric quantity is made more rationally accurately by said process.
See the method flow diagram that Fig. 1, Fig. 1 are detection mobile device battery electric quantities provided by the invention, mainly comprise the following steps:
Step S100, described mobile device detect its cell voltage every a schedule time, and judge whether to be in holding state;
If step S200 mobile device is in holding state, then the battery electric quantity when cell voltage by detecting calculates standby;
If step S300 mobile device is in non-standby state, continuous several times reads described cell voltage, when the voltage number of times read reaches a pre-determined number, then under this non-standby state, actual battery electricity equals the difference of the kwh loss value that battery electric quantity and that the last time records is specified.
For mobile phone above-mentioned steps be described in detail below and illustrate.
In the step s 100, start timing by arranging a timer, and the schedule time detecting cell voltage be set, when timer each schedule time is just by ADC(analog to digital conversion circuit) detect one-shot battery voltage, concrete detection method circuit diagram as shown in Figure 2
Wherein, V

In step s 200, also step is comprised:
Step S201, by searching the relation table of cell voltage and the battery electric quantity prestored, calculate battery when on standby electricity;
Step S202, judge described standby time battery electric quantity whether be less than the battery electric quantity that the last time records, if so, then this is recorded standby time battery electric quantity as actual battery electricity;
Step S203, if not, then the battery electric quantity recorded the last time is as actual battery electricity.
Cell voltage and battery electric quantity have a relation one to one, for the difference of battery, the corresponding relation of cell voltage and battery electric quantity is also not quite similar, the discharge curve of a kind of battery as shown in Figure 3, and set up cell voltage as shown in table 1 and the relation table of battery electric quantity according to this curve
| Voltage | 3.300 | 3.400 | 3.579 | 3.597 | 3.626 | 3.650 | 3.677 | 3.698 | 3.700 | 3.710 | 3.719 |

| Electricity | 42% | 50% | 56% | 62% | 68% | 76% | 77% | 83% | 88% | 92% | 100% |
The relation table of table 1 cell voltage and battery electric quantity
Wherein, when cell voltage is 4.2V, battery electric quantity is 100%.In the discharge process of battery, before cell voltage reaches 3.55V, the speed of electric discharge is very slow, after cell voltage is less than 3.55V, the velocity of discharge of battery increases rapidly, and Here it is why in mobile phone discharge process, under that is to say that mobile phone is in non-standby state, the cause that the electricity of battery can alter a great deal, for this situation, below according to data shown in table 1, battery electric quantity change is analyzed.
With V
oC=3.755V is example, and the internal resistance of cell is 0.15 ohm, and discharge electricity amount is 3mA, and now corresponding battery electric quantity is 50%,
When the handset is on standby:
I
oUT=3mA, then V
bAT=V
oC-I
oUT* R=3.755-0.003*0.15=3.75455V,
V
bATapproximate V
oC, the battery electric quantity that now mobile phone detects approximates actual battery electric quantity, and namely 50%.
When mobile phone heavy-current discharge, to surf the Net:
I
oUT=300mA, then V
bAT=V
oC-I
oUT* R=3.755 – 0.3*0.15=3.710V,
V
bATmuch smaller than V
oC, the battery electric quantity that now mobile phone detects is less than actual battery electric quantity, tables look-up 1 to know, is 32%.
Can draw according to above-mentioned analysis, when mobile phone is in holding state, the battery electric quantity that mobile phone detects is 50%, now mobile phone enters heavy-current discharge state, the battery electric quantity then detected is 32%, and when mobile phone enters holding state again, the battery electric quantity detected is again 50%, phenomenon that Here it is " telegram in reply ", therefore, after step sloo, the battery electric quantity battery detecting of mobile phone being divided into step S200 and step S300 to carry out in holding state and non-standby state two kinds of situations detects in the present invention.
Be the process flow diagram that the present invention arranges that 30 seconds timers carry out battery electric quantity measurement see Fig. 4, Fig. 4, when mobile phone by non-standby State Transferring to holding state time, perform step S202 and step S203, after performing step S201, the cell voltage V read by ADC
bATtable look-up and draw battery when on standby electricity Q
iDLE, compare Q
iDLEwith the battery electric quantity Q that the last time records
bATif, Q
iDLE<Q
bAT, then Q
bAT=Q
iDLE; Otherwise Q
bAT=Q
bAT.This step is to overcome " telegram in reply " phenomenon.
Further, in step S300, when that is to say that mobile phone is in non-standby state, by arranging a counter, the number of times reading cell voltage is controlled by this counter, and the calculating of kwh loss is carried out by reading the number of times of cell voltage, the timing of timer and discharge current, be specially:
Kwh loss value calculates according to following formula (1):
Q=NTI; Formula 2
Wherein, Q represents kwh loss value, and N represents the pre-determined number reading cell voltage under non-standby state, and T represents the schedule time, and I represents the discharge current of battery.In the present embodiment, the schedule time has the timing of timer to determine, pre-determined number that is to say the number of times reading cell voltage.
Again see Fig. 4, be set in mobile phone when being in non-standby state, the timing of timer is 30 seconds, when the discharge current of mobile phone is 150mA, the number of times reading cell voltage is 8 times, then can be calculated by formula 2, within every 4 minutes, battery electric quantity loss value is 1%, that is to say Q
bAT=Q
bAT-1%, when being in non-standby state whenever mobile phone, counter all adds 1, and counter initial value is 0, when counter reaches 7, and actual battery electric quantity Q
bAT=Q
bAT-1%.Therefore arranged by the combination of timer sum counter, under achieving non-standby state, battery electric quantity successively decreases according to the situation of change of reality again, makes the battery electric quantity of measurement more accurate.Certainly, battery electric quantity loss value 1% is 150mA at discharge current, and timer is 30S, and calculate when the number of times reading cell voltage is 8 times, battery electric quantity loss value is not limited to this value, determines according to actual conditions.
Further, in this embodiment of the present invention, the actual battery electricity that front and back record for twice is related, their mode obtaining the interative computation being utilization, the battery electric quantity head next time recorded is obtained by the battery electric quantity that the last time records, that is to say, in step S300, the difference of the kwh loss value that the battery electric quantity and that the actual battery electricity under mobile terminal is in non-standby state just equals once to record is specified, and battery electric quantity under mobile terminal is in holding state by compare that this records standby time battery electric quantity with on the battery electric quantity that once records make comparisons and draw.
