Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of battery charging control method and device, be applied particularly in electronic equipment, described electronic equipment can use multiple different charge parameter to charge, described charge parameter at least comprises charging current and charging voltage, when charging to battery, if receive first selection instruction of user, then search the first charge parameter of corresponding described first selection instruction, control the charging of described battery according to described first charge parameter; If do not receive first selection instruction of user, then the battery history inquiring about preservation uses information and adds up the corresponding relation of different charging interval section and the different charge parameter type drawn; According to the second charge parameter of described corresponding relation determination current time place charging interval section correspondence, control the charging of described battery according to described second charge parameter.By the embodiment of the present invention, achieve effective control of battery charging.
See Fig. 1, show the flow chart of a kind of battery charging control method embodiment 1 of the present invention, method described in the present embodiment is applied particularly in electronic equipment, and described electronic equipment can use multiple different charge parameter to charge, and described charge parameter comprises charging current and charging voltage.Described method can comprise:
Step 101: detect the first selection instruction whether receiving user, if so, enter step 102, if not, enter step 103.
After electronic equipment starts, after connecting power supply by power supply adaptor, namely can be electric device battery and charge, is described power electronic equipment by power supply.
In the present embodiment, described electronic equipment can use multiple different charge parameter to charge, and also namely electronic equipment charges according to charge parameter control battery, and described charge parameter comprises charging voltage and charging current.Charging voltage and charging current can refer to electronic equipment when charging to battery to the input voltage of battery and input current.Namely also electronic equipment can control the electric current that inputted by power supply adaptor and voltage, and inputs to battery, for described battery charges after conversion accordingly.The voltage that can reach after charging voltage refers to battery charging complete, if charging voltage reduces, then can affect the battery capacity after battery charging complete.
Use dissimilar charge parameter for battery charge time, be different on the impact of battery.Illustrate below:
The unit of battery capacity is mAh (MAH), and charging current C represents, 1C represents the electric current in battery 1 hour needed for from full tele-release to sky.Supposing that battery completely fills rear battery capacity is 1300mAH, then charging current can be used, and such as 0.1C and 130mA, 0.2C and 260mA etc. represent.
Then: when charging voltage is full charge pressure (i.e. battery after being full of accessible voltage), when charging current is 0.5C ~ 0.7C (this charging current is different according to different battery core performances), parameter is charged normal for battery.
When charging voltage is full charge pressure, when charging current is 1C ~ 1.5C (this charging current is different according to different battery core performances), i.e. big current quick charge parameter, the quick charge of battery can be realized, namely within the specific limits, when charging current is larger, battery charge time can be shorter.Under this quick charge parameter, the quick charge of battery can be realized, but charging current is larger, the useful life of battery can be affected.
When charging voltage is full charge pressure, when charging current is 0.2C ~ 0.3C (different according to different battery core performances), i.e. small area analysis charge parameter at a slow speed, under this at a slow speed charge parameter, contribute to the useful life extending battery, but the charging interval that corresponding battery is full of will be elongated.
When charging voltage is pressed lower than full charge, charging current is 0.2C ~ 0.3C, i.e. the health charge parameter of low-voltage small area analysis, and under this health charge parameter, the battery capacity after battery charging complete can reduce, and namely battery actual capacity is lower than completely filling capacity.Under this health charge parameter, more contribute to extending useful life of battery, but be directly proportional to power-on time due to battery capacity, therefore can shorten the power-on time of battery.
It should be noted that, the above-mentioned design parameter scope merely illustrating charging voltage in charge parameter and charging current, the battery according to battery can specifically can limit according to actual conditions by this parameter area.Under normal circumstances, charging current is 0.1C ~ 0.2C is that small area analysis charges at a slow speed, and being normal current charging at 0.2C ~ 0.8C, is big current quick charge when being greater than 0.8C.

Step 102: the first charge parameter searching corresponding described first selection instruction, controls battery charging according to described first charge parameter.
If receive described first selection instruction, then search should the first charge parameter of the first selection instruction.Concrete, can preserve the corresponding relation of charge parameter type and concrete charge parameter in advance, namely the charge parameter type of carrying according to the first selection instruction should find first charge parameter of corresponding the type.
After finding this first charge parameter, electronic equipment can be installed this first charge parameter and control battery charging, comprises electric current, voltage etc. that adjustment power supply adaptor inputs to electronic equipment.
Wherein, state described in and can comprise according to described first charge parameter control battery charging:
According to described first charge parameter, determine the first expected battery capacity after the charging of described battery.
Relatively whether present battery capacity is greater than described first expected battery capacity.
If so, described battery discharge is controlled to described first expected battery capacity.
If not, then control described battery according to described first charge parameter and be charged to described first expected battery capacity.
Described first expected battery capacity is less than battery full capacity, owing to can be conducive to extending the useful life of battery when battery capacity remains on lower than full capacity battery capacity.Such as, when described first charge parameter is the health charge parameter of low-voltage small area analysis, battery capacity after the battery charging complete that this health charge parameter is corresponding is about completely fills 70% of capacity, if then and the present battery capacity of battery is greater than this first expected battery capacity, then control battery discharge, such as battery is used to be described power electronic equipment, when battery capacity arrives described first expected battery capacity, then no longer continuing electric discharge, such as, is power electronic equipment by power supply again.When selecting low-voltage low current charge to make user, the first expected battery capacity contributing to its life-span that battery can be made to maintain.
Step 103: the battery history that inquiry is preserved uses information and adds up the corresponding relation of different charging interval section and the different charge parameter type drawn.
When not receiving the first selection instruction, do not charge immediately to battery, the history of first inquiring about the battery of preservation uses information and adds up the corresponding relation of different charging interval section and the different charge parameter drawn.
In the present embodiment, the history that electronic equipment can record every primary cell automatically uses information, charge information when battery charges and the use information after charging can be comprised, the charge parameter type such as, adopted when at every turn charging and charging interval section, the actual duration of charging, the charging in intervals of distance charging next time, the information such as the powered battery duration after charging complete.
The corresponding relation of different charging interval section and different charge parameter type is used information to add up to draw according to the history of described battery.
If inquiry is less than the corresponding relation of this charging interval section from different charge parameter, then can charge to battery according to predetermined charge parameter, described predetermined charge parameter can refer to the charge parameter with helping extend battery, the charge parameter at a slow speed that such as, small area analysis in step 101 is corresponding or health charge parameter corresponding to low-voltage small area analysis, normal charge parameter can certainly be adopted, to keep the balance of battery life and battery-powered time.
Different charging interval section can adopt multiple implementation from the arranging of corresponding relation of different charge parameter type, can introduce in detail below in embodiment.

According to the current charging moment, can determine which charging interval section it is positioned at, thus the second charge parameter of this charging interval section correspondence can be determined, battery charging can be controlled according to this second charge parameter.
Wherein, control battery charging according to described second charge parameter can comprise:
According to described second charge parameter, determine the second expected battery capacity after the charging of described battery;
Relatively whether present battery capacity is greater than described second expected battery capacity;
If so, described battery discharge is controlled to described second expected battery capacity;
If not, then control described battery according to described second charge parameter and be charged to described second expected battery capacity.
When described second charge parameter is low-voltage small area analysis, then can control battery charging according to above-mentioned steps.To contribute to the battery extended further.
In the present embodiment, electronic equipment can use different charge parameters to charge for battery.Or information can be used according to the history of battery and add up the corresponding relation of different charging interval section and the different charge parameter drawn according to first selection instruction of user, the charge parameter adopted when determining that this charges, by selecting different charge parameters in varied situations, automatically achieve the effective control to battery charging.
