Description
Technical field
The present invention relates to charging technique, in particular to the management method of a kind of terminal and a kind of battery status.
Background technology
At present, along with smart mobile phone is day by day universal and feature richness, application software are numerous, mobile phone charging problem perplexs all the more user.Although correct charging method is shutdown charging, most users can so not do.Because if shutdown, except omitting important phone, also possibly cannot dismiss the boring time.Therefore, what most users adopted is charging on one side, makes a phone call on one side or listens MP3, sees a film, browsing page, passes through bluetooth transmitting file etc.Present mobile phone is all supported this charging modes substantially, and its principle is as follows.
As shown in Figure 1, wherein, the maximum current of charger is charger current; Battery current is the charging current of battery; System power is the electric current of system consumption.Obviously, when circuit charge switch is during in closed condition, certainly exist following relation:
Charger current=battery current+system power
Obviously, in the certain situation of the capacity of battery, battery current is larger, and the charging interval is shorter; Battery current is less, and the charging interval is longer.Therefore, when charger current is constant, system power is larger, and battery current will be less, and the charging interval will be longer.That is to say, in charging, the electric current that charger provides is constant, if user charges, Yi Bian surf the Net, listen to the music, see a film, by bluetooth transmitting file etc., cause system power to increase on one side, will make battery current reduce, cause the charging interval to extend.Specifically can divide three kinds of situations:
When system power < charger current, along with the increase of system power, battery current reduces, and the charging interval extends, but eventually can be full of.
When system power=charger current, battery current=0.Battery does not charge, the complete feed system loss of electric current of charger.
When system power > charger current, battery current < 0.At this moment, battery does not only charge, and will give system power supply (now circuit charge switch is in open mode) on the contrary.
In sum, for current mobile phone, although after inserting charger, mobile phone can start to show the icon of charging, but battery whether speed, the needed time of having charged in real charged state, charging all do not show, domestic consumer also cannot know at all.
And in correlation technique, although can learn the concrete charged state of battery, be passive monitoring, can not initiatively change the charge condition of terminal; Meanwhile, in the charging process of battery, along with the increase in charging interval, battery temperature may raise to the use of terminal due to for a long time large current charge or user, and life-span or fail safe that terminal is used threaten.

Step 304, judge whether that battery charging state has higher priority, battery charging state and battery temperature state have priority separately, certainly, the priority here can be default in terminal, also can according to the needs of oneself, be carried out freely revising or setting by user.If battery charging state has higher priority, enter step 306, otherwise enter step 314.
Step 306, judge that battery is whether in just in charged state, here for battery charging state, have higher priority and be construed as, user is more concerned about the charge condition of battery, wishes to make battery be full of electricity within the shorter time, simultaneously, in fact for battery actually in charged state or negative charged state are not unimportant, key be battery whether can really obtain and storing electricity whether in just in charged state, if, enter step 312, otherwise enter step 308.
Step 308, judges that whether battery temperature surpasses default temperature threshold, judgement battery really obtaining and storing electricity after, more whether consider if so, to enter excess Temperature step 310, otherwise to finish.
Step 310, reduces the charging current of terminal, because charging current is when excessive, can cause battery to heat up, and therefore, by reducing charging current, reduces battery temperature, life-span and the fail safe of protection terminal and battery.After adjusting, return to step 308, detected temperatures state.
Step 312, reduce the kwh loss of terminal, because the kwh loss of terminal is excessive, although may cause being connected to charger, but battery can not obtain or storing electricity, even to provide for the kwh loss of terminal a part of electric weight, therefore, by a part of application program is turned down or closed to the screen intensity of terminal, the kwh loss of terminal is reduced, and battery restarts to obtain from charger and storing electricity, realizes real charging, or increase the speed of obtaining electric weight, make to be full of electric time shorten.After adjusting, return to step 306, battery charging state is detected.
Step 314, when battery temperature state has higher priority, judges whether battery temperature surpasses default temperature threshold.In long-time charging or terminal charge process, use application program wherein, may cause the temperature of battery to raise, this can shorten the useful life of terminal on the one hand, cross on the other hand long high temperature and may bring potential safety hazard, thereby by a default temperature threshold, when temperature surpasses this threshold value, think high temperature and carry out cooling measure.Here, if surpass threshold value, enter step 320, otherwise enter step 316.
Step 316, judge battery whether in just in charged state, because the priority of battery temperature state is higher, no matter therefore whether battery charges, be all monitor temperature situation first, only, in the situation that temperature is no more than temperature threshold, just can carry out the detection of battery charging state.Here, if so, enter step 318, otherwise finish.
Step 318, reduces the kwh loss of terminal, after adjusting, returns to step 316, detects battery charging state, until in just in charged state.
Step 320, the charging current of reduction terminal, after adjusting, returns to step 314, detects battery temperature state, until battery temperature is no more than default temperature threshold.
