Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of acquisition methods of information about power, as shown in Figure 1, comprising:
101, electronic equipment judges that whether system state hurdle is available, if the status bar of electronic equipment can be used, carries out 102; If the status bar of electronic equipment is unavailable, carry out 103.
Wherein, electronic equipment is for mobile phone, the apparatus such as computer that can discharge and recharge battery, can be for lithium polymer battery such as this battery etc.
Exemplary, the operating system of electronic equipment can provide the system interface that obtains current electric quantity, for example the operating system of Apple products exists state of a control hurdle to show the interface of information about power, the information about power that this interface provides is accurate to 0.01, therefore, can, by judging that whether status bar is available, obtain accurate information about power.
Exemplary, can judge that by the version information of decision operation system whether status bar is available.For example,, for the ios system of Apple products, if the version of ios system below ios6.0, can directly determine that status bar is available; If system version is ios6.0 or higher than ios6.0, can first judge that whether status bar is in hidden state, if status bar is not hidden, determine that status bar can use; If status bar in hidden state, determines that status bar is unavailable.
102, from status bar, obtain the current electric quantity information of electronic equipment.
103, from system interface, obtain information about power;
104, the information about power obtaining from system interface and the last information about power obtaining from status bar are compared; If electronic equipment is in charged state, using the large information about power of numerical value as current electric quantity information; If electronic equipment is in non-charged state, using the little information about power of numerical value as current electric quantity information.
Operating system has the system interface that information about power can be provided, and the information about power of this system interface is all 0.05 multiple, compares with the information about power obtaining from status bar, less better in degree of accuracy.
At this moment, the first electric weight by the last time obtains from status bar, compares with the second electric weight obtaining from system interface after switching, according to the residing state of electronic equipment, chooses suitable electric weight numerical value as current electric quantity information.For example, if electronic equipment in charged state, its battery electric quantity should be the trend rising, and now chooses larger that of numerical value in the first electric weight and the second electric weight as current electric quantity information.On the contrary, if electronic equipment in non-charged state, its battery electric quantity is downward trend, now chooses less that of numerical value in the first electric weight and the second electric weight more suitable as current electric quantity information.
The embodiment of the present invention provides a kind of acquisition methods of information about power, by system state hurdle, obtain more accurate information about power, and when unavailable on system state hurdle, from system interface, obtain information about power, and the information about power obtaining from system interface and the last information about power obtaining from status bar, choose suitable electric weight numerical value as current electric quantity information, can improve the degree of accuracy of information about power.

Exemplary, for iPhone equipment, the total electric weight of battery is 1420mAh, when the battery charging stage is rapid charge, charging current is 1000mA, when the battery charging stage is trickle charge, charging current is 300mA, and the duration of charging that can obtain battery electric quantity from 0% to 100% according to charging stage and charge characteristic can be:
T=1420*0.8/1000*1.2+1420*0.2/300*1.2=2.4992
And for the second reference time, generally, battery is approximately 40 minutes entering trickle charge stage to the duration that reaches capacity completely, like this, according to the current electric quantity information of battery, the first reference time, the second reference time and the first computing formula, can obtain the charging excess time that battery charged in rapid charge stage and trickle charge stage.Wherein, the first computing formula is:
T′=(1-C
1)*T+T
1
Wherein, T' represents the excess time of charging, C
1the current electric quantity information of battery while representing charging, T represents the first reference time, T
1represented for the second reference time.
For instance, battery current electric quantity is 60%, in the rapid charge stage, be 2.5 hours the first reference time, namely 150 minutes, be 40 minutes the second reference time, according to the first computing formula, calculates the charging excess time of T '=(1-60%) * 150+40=100 minute.
107, according to stating duration of charging and second computing formula of battery in the trickle charge stage, calculate the excess time of charging.
