Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The embodiment of the invention discloses a kind of battery charging control method and device, specifically be applied in the electronic equipment, described electronic equipment can use a plurality of different charge parameters to charge, described charge parameter comprises charging current and charging voltage at least, when battery is charged, if receive the first selection instruction of user, then search the first charge parameter of corresponding described the first selection instruction, control described battery charging according to described the first charge parameter; If do not receive the first selection instruction of user, the corresponding relation of the different charging interval sections that draw of the inquiry historical use information of battery of preserving and adding up and different charge parameter types then; Determine the second charge parameter of current time place charging interval section correspondence according to described corresponding relation, control described battery charging according to described the second charge parameter.By the embodiment of the invention, realized effective control of battery charging.
Referring to Fig. 1, show the flow chart of a kind of battery charging control method embodiment 1 of the present invention, the described method of the present embodiment specifically is applied in the electronic equipment, and described electronic equipment can use a plurality of different charge parameters to charge, and described charge parameter comprises charging current and charging voltage.Described method can comprise:
Step 101: detect the first selection instruction that whether receives the user, if so, enter step 102, if not, enter step 103.
After electronic equipment starts, behind power supply adaptor connection power supply, 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 a plurality of different charge parameters to charge, and also is that 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 input voltage and input current to battery when battery is charged.Also be that electronic equipment can be controlled electric current and the voltage by the power supply adaptor input, and through inputing to battery after the corresponding conversion, be described battery charging.Charging voltage refers to the voltage that can reach after battery charging is finished if charging voltage reduces, then can affect the battery capacity after the battery charging is finished.
When using dissimilar charge parameter to charge as battery, be different on the impact of battery.The below illustrates:
The unit of battery capacity is mAh (MAH), and charging current represents with C, and 1C represents in the battery 1 hour the electric current required from full tele-release to sky.Suppose that it is 1300mAH that battery completely fills rear battery capacity, then charging current can be used, and for example 0.1C is 130mA, and 0.2C is 260mA etc. expression.
Then: when charging voltage is full charging voltage (being accessible voltage after battery is full of), when charging current is 0.5C~0.7C (this charging current according to different battery core performances and difference), be the parameter that charges normal of battery.
When charging voltage is full charging voltage, when charging current is 1C~1.5C (this charging current according to different battery core performances and difference), i.e. large electric current quick charge parameter, can realize the quick charge of battery, namely within the specific limits, when charging current was larger, the battery charging interval can be shorter.Under this quick charge parameter, can realize the quick charge of battery, but charging current is larger, can affect the useful life of battery.
When charging voltage is full charging voltage, when charging current was 0.2C~0.3C (according to different battery core performances and difference), namely little electric current is charge parameter at a slow speed, at this at a slow speed under the charge parameter, help to prolong the useful life of battery, but the charging interval that corresponding battery is full of will be elongated.
When charging voltage was lower than full charging voltage, charging current was 0.2C~0.3C, i.e. the health charge parameter of the little electric current of low-voltage, and under this health charge parameter, the battery capacity after the battery charging is finished can reduce, and namely the battery actual capacity is lower than completely filling capacity.Under this health charge parameter, more help to prolong the useful life of battery, but because battery capacity is directly proportional with power-on time, therefore can shorten the power-on time of battery.
Need to prove, above-mentionedly just for example understand charging voltage in the charge parameter and the design parameter scope of charging current, can specifically limit according to actual conditions by this parameter area according to the battery of battery.Generally, charging current is that 0.1C~0.2C is that little electric current charges at a slow speed, is the normal current charging at 0.2C~0.8C, is large electric current quick charge during greater than 0.8C.
Wherein, the first selection instruction refers to the different charge parameter that the user arranges according to electronic equipment, and when selecting suitable charge parameter and trigger transmission, this first selection instruction carries the charge parameter type.After electronic equipment connected power supply by power supply adaptor, the user can select different charge parameters to come battery is charged according to actual conditions.
User's charging option that can provide according to electronic equipment is for example selected the charge parameter type that needs, and for example charge parameter has at a slow speed namely triggered the first selection instruction, and this first selection instruction is carried the charge parameter type, i.e. charge parameter at a slow speed.
Step 102: search the first charge parameter of corresponding described the first selection instruction, according to the charging of described the first charge parameter control battery.
If receive described the first selection instruction, then search the first charge parameter that should the first selection instruction.Concrete, the corresponding relation of charge parameter type and concrete charge parameter can pre-save be arranged, the charge parameter type of carrying according to the first selection instruction namely should find first charge parameter of corresponding the type.
After finding this first charge parameter, electronic equipment can be installed this first charge parameter control battery charging, comprises that the adjustment power supply adaptor inputs to the electric current of electronic equipment, voltage etc.
Wherein, described stating according to the charging of described the first charge parameter control battery can comprise:
According to described the first charge parameter, determine the first expectation battery capacity after described battery charges.
Whether more current battery capacity estimates battery capacity greater than described first.
If so, control described battery discharge and estimate battery capacity to described first.
If not, then control described battery according to described the first charge parameter and be charged to described the first expectation battery capacity.
Described first estimates that battery capacity less than the battery full capacity, can be conducive to prolong the useful life of battery when remaining on the battery capacity that is lower than full capacity owing to battery capacity.For example during described the first charge parameter health charge parameter that is the little electric current of low-voltage, battery capacity after the battery charging that this health charge parameter is corresponding is finished is about completely fills 70% of capacity, then and if the current battery capacity of battery first is estimated battery capacity greater than this, then control battery discharge, for example using battery is described power electronic equipment, when battery capacity arrives described the first expectation battery capacity, then no longer continue discharge, be power electronic equipment by power supply again for example.So that during user selection low-voltage low current charge, can so that first of its life-span that helps that battery is kept estimate battery capacity.
Step 103: the different charging interval sections that the historical use information of the battery that inquiry is preserved and adding up draws and the corresponding relation of different charge parameter types.
When not receiving the first selection instruction, immediately battery is not charged, at first the history of the battery preserved of inquiry is used information and is added up the corresponding relation of the different charging interval sections that draw and different charge parameters.
In the present embodiment, the electronic equipment automatically history of the every primary cell of record uses information, charge information in the time of can comprising the battery charging and the use information after the charging, the charge parameter type that adopts when for example 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 powered battery duration after charging is finished.
Can add up the corresponding relation that draws different charging interval sections and different charge parameter types according to the history use information of described battery.
If inquiry is less than the corresponding relation of this charging interval section from different charge parameters, then can charge to battery according to predetermined charge parameter, described predetermined charge parameter can refer to the charge parameter that helps prolong battery, the at a slow speed charge parameter that for example the little electric current in the step 101 is corresponding or health charge parameter corresponding to the little electric current of low-voltage, can certainly adopt normal charge parameter, to keep the balance of battery life and battery-powered time.
Different charging interval sections can adopt multiple implementation from the arranging of corresponding relation of different charge parameter types, can introduce in detail among the embodiment below.
Step 104: determine the second charge parameter of current time place charging interval section correspondence according to described corresponding relation, control described battery charging according to described the second charge parameter.
According to current charging constantly, can determine which charging interval section it is positioned at, thereby can determine the second charge parameter of this charging interval section correspondence, can be according to this second charge parameter control battery charging.
Wherein, can comprise according to the charging of described the second charge parameter control battery:
According to described the second charge parameter, determine the second expectation battery capacity after described battery charges;
Whether more current battery capacity estimates battery capacity greater than described second;
If so, control described battery discharge and estimate battery capacity to described second;
If not, then control described battery according to described the second charge parameter and be charged to described the second expectation battery capacity.
When described the second charge parameter is the little electric current of low-voltage, then can control the battery charging according to above-mentioned steps.With the battery that further helps to prolong.
In the present embodiment, electronic equipment can use different charge parameters to charge as battery.The different charging interval sections that can use information add up to draw according to the first selection instruction of user or according to the history of battery and the corresponding relation of different charge parameters, the charge parameter that adopts when determining this charging, by under different situations, selecting different charge parameters, automatically realized the effective control to the battery charging.
