104, when described first gathers electric weight and be the current true electric weight of battery, upgrade the described first original electric weight and be described first and gather electric weight; Otherwise, calculate the current estimation electric weight of described battery according to described theoretical charge/discharge electricity amount, then upgrading the described first original electric weight is described estimation electric weight.
The primary cell electric weight upgrade to finish, and distributes after the described renewal the first original electric weight to each functional module of mobile terminal system.
The present invention also provides a kind of the second embodiment of method of mobile terminal to update battery electric quantity, as shown in Figure 2, said method comprising the steps of:
Gather cell voltage when 200, portable terminal starts and draw battery electric quantity by the voltage electric weight conversion table of setting up in advance, be designated as the second original electric weight; Start simultaneously a timer, whether enter low-power consumption mode at described timer in predetermined time to detect mobile terminal system.
201, detect mobile terminal system in predetermined time at described timer and whether enter low-power consumption mode, do not enter low-power consumption mode if detect mobile terminal system, then when described timer expiry, gather cell voltage, and draw the second current collection electric weight of battery by described voltage electric weight conversion table.
202, described the second collection electric weight and the described second original electric weight are compared, judge according to the charging and discharging state of portable terminal whether described the second collection electric weight is the current true electric weight of battery.In the embodiment of the invention, described determination methods is: when portable terminal is in charged state and described second and gathers electric weight less than or equal to described the second original electric weight, perhaps when portable terminal is in non-charged state and described second and gathers electric weight more than or equal to described the second original electric weight, judging described second, to gather electric weight be not the current true electric weight of battery.
203, when described second gathers electric weight and be not the current true electric weight of battery, then keep the described second original electric weight constant; Otherwise, if portable terminal be in charged state then control upgrade the described second original electric weight be the described second original electric weight add 1 and, if then upgrade when portable terminal is in for non-charged state the described second original electric weight be original electric weight subtract 1 poor.
At last, the second original electric weight was to each functional module of mobile terminal system after distribution was upgraded.
Particularly, the below's act specific embodiment is further explained explanation to the method for mobile terminal to update battery electric quantity of the present invention.As shown in Figure 3, when starting mobile terminal system, gather cell voltage and draw battery electric quantity by the voltage electric weight conversion table of setting up in advance, be designated as original electric weight C1; And start a timer.Detect mobile terminal system in predetermined time at described timer and whether enter low-power consumption mode, when detecting described mobile terminal system and enter low-power consumption mode, the record move terminal system current time is T1, closes simultaneously described timer.Specifically see embodiment one and embodiment two to two kinds of situations of operation of battery electric quantity update this moment.
Embodiment one: mobile terminal system has entered low-power consumption mode, and described portable terminal is in charged state.
Shown in 1 branch among Fig. 3, portable terminal receives the operational order that the user lights screen, wake mobile terminal system up so that it enters non-low-power consumption mode, namely enter high power consumption mode, the record move terminal system current time is T2, and drawing the time span that mobile terminal system is in low-power consumption mode is T=T2-T1.The ADC that control starts in the mobile terminal system gathers cell voltage, draws corresponding battery electric quantity by described voltage electric weight conversion table, namely draws the current collection electric weight of battery, is designated as C2; Calculate simultaneously that the theoretic maximum of described battery of mobile terminal is filled with electric weight in described time T, be designated as Q0.The computational methods of described Q0 are: the charging ability K(that at first measures described battery is the maximum electric weight that per second can be filled with, charge to the 1000mAh battery such as the 360mA charging current, K=0.01 so), K being multiply by described time T namely obtains the maximum of described battery in time T and is filled with electric weight Q0.
Control compares described C2 and C1, if C2＜=C1, because its battery electric quantity can not reduce when portable terminal was in charged state, therefore can judge the certainly not current true electric weight of battery of C2, keep described battery capacity of mobile terminal this moment is C1, and namely giving tacit consent to the current true electric weight of battery is C1.
If described C2〉C1, the difference and the described Q0 that then further described C2 are subtracted C1 compare, as C2-C1〉during Q0, because described Q0 is that described battery of mobile terminal theoretic maximum in time T is filled with electric weight, therefore can judge that described C2 is not the current true electric weight of battery, then control control the more original electric weight C1=C1+Q0 of new record with C1 and Q0's and as the current estimation electric weight of battery.When C2-C1＜=Q0, can judge that then described C2 is the current true electric weight of battery, C1=C2 is upgraded in control.Then the described original electric weight after will upgrading is distributed to each functional module of described mobile terminal system, restarts simultaneously described timer.Specifically can realize by the following is code:
If (current collection electric weight C2〉record original electric weight C1 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 original electric weight before battery electric quantity keeps ignores the battery electric quantity that current collection obtains;
}
For example: the original electric weight C1=50(battery electric quantity of hypothetical record is 100 to the maximum, 50 is 50% electric weight), current collection electric weight C2=53, T1=12:30:00, T2=12:31:40, described battery of mobile terminal charging ability K=0.01 is supposed in T=100 second so, can get Q0=1, because C2-C1〉Q0, being C2〉C1+Q0, so the current true electric weight of the battery that estimates is 51 (they being C1+Q0), upgrade original electric weight C1=51.Each functional module that original electric weight 51 was given mobile terminal system after distribution was upgraded restarts described timer simultaneously.
Embodiment two: mobile terminal system has entered low-power consumption mode, and described portable terminal is in non-charged state.
Shown in 2 branches among Fig. 3, receive the operational order that the user wakes screen up, wake mobile terminal system up and make it enter high power consumption mode, the record move terminal system current time is T02, and drawing the time span that mobile terminal system is in low-power consumption mode is T0=T02-T1.The ADC that simultaneously control starts in the mobile terminal system gathers the current voltage of battery, draws the current collection electric weight of battery by the corresponding table of described voltage electric weight, is designated as C02; Calculate simultaneously at the theoretic maximum power consumption electric weight of described time T 0 interior battery, be designated as Q00.
Described C02 and C1 are compared, if C02 〉=C1, battery electric quantity may increase scarcely when being in non-charged state owing to portable terminal, therefore can judge the certainly not current true electric weight of battery of C02, do not upgrade battery electric quantity this moment, and namely keeping battery electric quantity is original electric weight C1.
If described C02＜C1, the value and the described Q00 that then further described C1 are subtracted C02 compare, as C1-C02〉during Q00, because described Q00 is that described battery of mobile terminal is at time T 0 interior theoretic maximum power consumption electric weight, therefore can judge that described C02 is not the current true electric weight of battery, control with the difference of C1-Q00 as the current estimation electric weight of battery; C1=C1-Q00 is upgraded in control.When C1-C02＜=Q00, can judge that then it is the current true electric weight of battery that described C02 is, C1=C02 is upgraded in control.Then the original electric weight C1 after will upgrading is distributed to each functional module in the mobile terminal system, restarts simultaneously described timer, and again monitors described portable terminal and whether entered low-power consumption mode.Specifically can realize by the following is code:
If (original electric weight C1 and non-charged state and the low-power consumption mode of current collection electric weight C02＜record)
{
If(C02<C1-K*T0)
Battery electric quantity update is C1-K*T0;
Else
Battery electric quantity update is C02;
}
Else
{
Keeping the value of battery electric quantity is C1, ignores the battery electric quantity of current collection;
}
For example: the original electric weight C1=50 of hypothetical record, C2=47, T1=12:30:00, T02=12:40:00, K=0.01, T0=600 second so, Q00=6 are because C02＜C1 and C02〉C1-K*T0, so original electric weight C1 just should be updated to C02, be that current battery electric quantity update is 47, and be distributed to other modules uses of mobile terminal system.
Therefore, as described in above-mentioned 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 low-power consumption mode in the time period the theoretic maximum of described battery of mobile terminal be filled with electric weight (charged state) or maximum power consumption electric weight (non-charged state).When described collection electric weight charge status obvious and described battery of mobile terminal is run counter to, be that the described collection electric weight of charged state is on the contrary less than described original electric weight, perhaps described collection electric weight then keeps battery electric quantity constant on the contrary greater than described original electric weight during non-charged state; When the changing value of the original electric weight that gathers the relatively last record of electric weight exceeds the theoretic maximum charge/discharge electricity amount of battery, be filled with electric weight (charged state) or maximum power consumption electric weight (non-charged state) estimates the current true electric weight of battery according to described maximum; Otherwise gather collection electric weight that cell voltage obtains as the current true electric weight of battery take current ADC, control battery electric quantity after the battery electric quantity of new record more and distribution are upgraded to other functional modules of mobile terminal system.
Be specific embodiment one, two based on above-mentioned the first embodiment, the invention provides a kind of portable terminal that adopts the method for described mobile terminal to update battery electric quantity, such as Fig. 4, comprising:
