Primary cell electricity upgrades and terminates, and after distributing described renewal, the first initial charge is to each functional module of mobile terminal system.
Present invention also offers a kind of second embodiment of method of mobile terminal to update battery electric quantity, as shown in Figure 2, said method comprising the steps of:
200, gather cell voltage when mobile terminal starts and draw battery electric quantity by the voltage electricity conversion table set up in advance, being designated as the second initial charge; Start a timer simultaneously, whether within described timer predetermined time, enter low-power consumption mode to detect mobile terminal system.
201, within described timer predetermined time, detect mobile terminal system and whether enter low-power consumption mode, if do not detect, mobile terminal system enters low-power consumption mode, then gather cell voltage when described timer expiry, and draw by described voltage electricity conversion table the second collection electricity that battery is current.
202, gather electricity and described second initial charge by described second to compare, judge described second collection electricity whether as the true electricity that battery is current according to the charging and discharging state of mobile terminal.In the embodiment of the present invention, described determination methods is: when mobile terminal is in charged state and described second collection electricity is less than or equal to described second initial charge, or when mobile terminal be in non-charged state and described second gather electricity be more than or equal to described second initial charge time, judging described second, to gather electricity be not the current true electricity of battery.

Finally, distribution upgrades rear second initial charge to each functional module of mobile terminal system.
Particularly, lift the method for specific embodiment to mobile terminal to update battery electric quantity of the present invention to be below further explained.As shown in Figure 3, when starting mobile terminal system, gather cell voltage and draw battery electric quantity by the voltage electricity conversion table set up in advance, being designated as initial charge C1; And start a timer.Within described timer predetermined time, detect mobile terminal system whether enter low-power consumption mode, when detecting that described mobile terminal system enters low-power consumption mode, record move terminal system current time is T1, closes described timer simultaneously.Now to operation two kinds of situations of battery electric quantity update, specifically see embodiment one and embodiment two.
Embodiment one: mobile terminal system enters low-power consumption mode, and described mobile terminal is in charged state.
As shown in Tu3Zhong 1 branch, mobile terminal receives the operational order that user lights screen, wake mobile terminal system up and enter non-low-power consumption mode to make it, namely high power consumption mode is entered, record move terminal system current time is T2, show that the time span that mobile terminal system is in low-power consumption mode is T=T2-T1.Control the ADC started in mobile terminal system and gather cell voltage, draw corresponding battery electric quantity by described voltage electricity conversion table, namely draw and be designated as C2 by the collection electricity that battery is current; Calculate that described battery of mobile terminal in described time T is theoretic is maximumly filled with electricity simultaneously, be designated as Q0.The computational methods of described Q0 are: first measure the charging ability K(of described battery and the maximum electricity be filled with per second, such as 360mA charging current is charged to 1000mAh battery, so K=0.01), K is multiplied by described time T and namely obtains maximum in time T of described battery and be filled with electricity Q0.
Described C2 and C1 is controlled to compare, if C2<=C1, because when mobile terminal is in charged state, its battery electric quantity can not reduce, therefore the C2 true electricity that certainly not battery is current can be judged, now maintaining described battery capacity of mobile terminal is C1, and the true electricity namely giving tacit consent to battery current is C1.
If described C2>C1, the difference and the described Q0 that then further described C2 are subtracted C1 compare, as C2-C1>Q0, maximumly electricity is filled with because described Q0 is that described battery of mobile terminal is theoretic in time T, therefore can judge that described C2 is not the current true electricity of battery, control C1 and Q0's and as the current estimation electricity of battery, then control the initial charge C1=C1+Q0 of more new record.As C2-C1<=Q0, then can judge that described C2 is the current true electricity of battery, control to upgrade C1=C2.Then the described initial charge after renewal is distributed to each functional module of described mobile terminal system, restarts described timer simultaneously.Specifically by the following is codes implement:
If (the initial charge C1 that current collection electricity C2> records and charged state and low-power consumption mode)
{
If(C2>C1+K*T)
Battery electric quantity update is C1+K*T;
Else
Battery electric quantity update is C2;
}
Else
{
The value C1 of the initial charge before battery electric quantity keeps, ignores the current battery electric quantity gathering acquisition;
}
Such as: the initial charge C1=50(battery electric quantity of hypothetical record is 100 to the maximum, 50 be 50% electricity), current collection electricity C2=53, T1=12:30:00, T2=12:31:40, so T=100 second, suppose described battery of mobile terminal charging ability K=0.01, can obtain Q0=1, due to C2-C1>Q0, i.e. C2 > C1+Q0, so the current true electricity of the battery estimated is 51 (i.e. C1+Q0), upgrades initial charge C1=51.After distribution upgrades, initial charge 51 is to each functional module of mobile terminal system, restarts described timer simultaneously.
Embodiment two: mobile terminal system enters low-power consumption mode, and described mobile terminal is in non-charged state.
As shown in Tu3Zhong 2 branch, receive the operational order that user wakes screen up, waking mobile terminal system up makes it enter high power consumption mode, and record move terminal system current time is T02, show that the time span that mobile terminal system is in low-power consumption mode is T0=T02-T1.Control the ADC started in mobile terminal system simultaneously and gather the current voltage of battery, drawn by described voltage electricity correspondence table and be designated as C02 by the collection electricity that battery is current; Calculate the theoretic maximum power consumption electricity of battery in described time T0 simultaneously, be designated as Q00.
Described C02 and C1 is compared, if C02>=C1, because when mobile terminal is in non-charged state, battery electric quantity may increase scarcely, therefore the C02 true electricity that certainly not battery is current can be judged, now do not upgrade battery electric quantity, namely maintaining battery electric quantity is initial charge C1.
If described C02<C1, the value and the described Q00 that then further described C1 are subtracted C02 compare, as C1-C02>Q00, because described Q00 is described battery of mobile terminal theoretic maximum power consumption electricity in time T0, therefore can judge that described C02 is not the current true electricity of battery, control the difference of C1-Q00 as the current estimation electricity of battery; Control to upgrade C1=C1-Q00.As C1-C02<=Q00, then can judge that described C02 is is the current true electricity of battery, controls to upgrade C1=C02.Then the initial charge C1 after upgrading is distributed to each functional module in mobile terminal system, restarts described timer simultaneously, and again monitor described mobile terminal and whether enter low-power consumption mode.Specifically by the following is codes implement:
If (the initial charge C1 that current collection electricity C02 < records and non-charged state and low-power consumption mode)
{
If(C02<C1-K*T0)
Battery electric quantity update is C1-K*T0;
Else
Battery electric quantity update is C02;
}
Else
{
The value keeping battery electric quantity is C1, ignores the battery electric quantity of current collection;
}
Such as: the initial charge C1=50 of hypothetical record, C2=47, T1=12:30:00, T02=12:40:00, K=0.01, so T0=600 second, Q00=6, due to C02 < C1 and C02 > C1-K*T0, so initial charge C1 just should be updated to C02, namely current battery charge is updated to 47, and other modules being distributed to mobile terminal system use.
Therefore, as as described in above-described embodiment one, two, when mobile terminal system enters high power consumption mode by low-power consumption, according to battery charging ability or power consumption ability, estimate that described battery of mobile terminal within the low-power consumption mode time period is theoretic is maximumly filled with electricity (charged state) or maximum power consumption electricity (non-charged state).When described collection electricity charge status that is obvious and described battery of mobile terminal is run counter to, namely gather electricity described in charged state and be less than described initial charge on the contrary, or described collection electricity is greater than described initial charge on the contrary during non-charged state, then keep battery electric quantity constant; When the changing value of the initial charge gathering the relatively last record of electricity exceeds the theoretic maximum charge/discharge electricity amount of battery, be maximumly filled with electricity (charged state) or maximum power consumption electricity (non-charged state) estimates the current true electricity of battery according to described; Otherwise gather collection electricity that cell voltage obtains for the current true electricity of battery with current ADC, control the battery electric quantity of more new record and distribution upgrade after battery electric quantity to other functional modules of mobile terminal system.
