Referring to Fig. 2, being a kind of flow diagram of cell voltage method of adjustment provided by the embodiments of the present application, it is applied to
Mobile terminal 100 shown in FIG. 1.The detailed process and step of this method are elaborated with reference to Fig. 2.
Step S201 is monitored the Current Temperatures of battery 140, and determines and monitor in the temperature range to prestore
Target temperature range belonging to Current Temperatures.
Step S202, using the corresponding voltage threshold of the target temperature range as target corresponding with the Current Temperatures
Voltage threshold.
In the present embodiment, different temperatures range and the preset and different temperatures model are stored in mobile terminal 100
Enclose corresponding voltage threshold.Wherein, the different temperatures range and the corresponding voltage threshold of the different temperatures range can roots
It is configured in advance according to the characteristic curve of the battery 140 of mobile terminal 100, the present embodiment is without limitation.
In detail, the Current Temperatures of battery 140 can be acquired in real time by the temperature such as temperature sensor sampler.Its
In, refer to once being acquired to the temperature of battery 140 at interval of preset duration in real time, the preset duration can be according to reality
Demand is flexibly arranged, such as can be 0.5 second, 1 second, 2 seconds etc., and the present embodiment is without limitation.
For each collected Current Temperatures, the temperature belonging to the Current Temperatures is found out in the temperature range to prestore
Target temperature range of the range as the Current Temperatures.For example, it is assumed that prestored in mobile terminal 100 15 DEG C -45 DEG C and 45 DEG C -
55 DEG C of two temperature ranges can determine that the Current Temperatures belong to 15 if the Current Temperatures of collected battery 140 are 22 DEG C
DEG C -45 DEG C of this temperature ranges, i.e. the target temperature range of the Current Temperatures is 15 DEG C -45 DEG C.
After determining target temperature range, you can it is corresponding to obtain the target temperature range in the voltage threshold to prestore
Voltage threshold, and using the voltage threshold got as target voltage threshold corresponding with the Current Temperatures.
Still taking the above example as an example, it is assumed that 15 DEG C -45 DEG C corresponding voltage thresholds of temperature range are a, temperature range 45
DEG C of -55 DEG C corresponding voltage thresholds are b.Then, 15 DEG C of target temperature range for determining 22 DEG C of above-mentioned Current Temperatures -45 DEG C it
Afterwards, the corresponding voltage threshold a of 15 DEG C -45 DEG C this ranges can be directly acquired as 22 DEG C of corresponding target voltages of Current Temperatures
Threshold value.
Step S203 is monitored the current voltage of the battery 140, according to the current voltage monitored and the mesh
The magnitude relationship for marking voltage threshold, controls the charging and discharging state of the battery 140, make the voltage of the battery 140 with
The Current Temperatures match.
In implementation process, after determining the target voltage threshold of the Current Temperatures, it can be acquired by voltameter
The current voltage of the battery 140, and collected current voltage is compared with the target voltage threshold.Then, root
The charging and discharging state of the battery 140 is adjusted according to comparison result.
In the present embodiment, the target voltage threshold is that the battery 140 is suitable under the target temperature range
Operating voltage.The voltage of battery 140 matches with the Current Temperatures, can be that the voltage of battery 140 reaches under Current Temperatures
Suitable voltage.
Based on this, step S203 may include following sub-step：
When the current voltage of the battery 140 be more than the target voltage threshold when, to the battery 140 discharge with
Reduce the current voltage of the battery 140；
When the current voltage of the battery 140 be less than the target voltage threshold when, to the battery 140 charge with
The current voltage of the battery 140 is set to increase.
In this way, can operating voltage suitable under Current Temperatures be adjusted to the current voltage of the battery 140, to prolong
The service life of long battery 140.
Wherein, the target voltage threshold can be according to the work suitable under the target temperature range of the battery 140
It is configured as voltage.Also, in different situations, the suitable voltage of battery 140 is different.In a kind of specific embodiment party
In formula, the suitable voltage of battery 140 can be target voltage threshold corresponding with the Current Temperatures.
Such as shown in Fig. 3, Fig. 3 is a kind of characteristic curve schematic diagram of soft-package battery 140.Wherein, when the temperature of battery 140
When less than 43 DEG C, suitable operating voltage is 4.1V-4.4V, then can will be less than the corresponding voltage of 43 DEG C of this temperature ranges
Threshold value is set as 4.4V.When 140 temperature of battery is more than 45 DEG C, suitable operating voltage is 4.1V or so, then can will be big
It is set as 4.1V in the corresponding voltage threshold of 45 DEG C of this temperature ranges.
In this way, when the target temperature range of the battery 140 is less than 43 DEG C of this temperature ranges, if detecting described
The current voltage of battery 140 is less than 4.4V, and mobile terminal 100 can charge to the battery 140, until the battery 140
Current voltage when being more than 4.4V, mobile terminal 100 can discharge to the battery 140.In this way, the battery can be made
140 voltage maintains 4.4V or so.
When the target temperature range of the battery 140 is more than 45 DEG C of this temperature ranges, if detecting the battery
140 current voltage is less than 4.1V, and mobile terminal 100 can charge to the battery 140, until the battery 140 is worked as
When preceding voltage is more than 4.1V, mobile terminal 100 can discharge to the battery 140.In this way, the battery 140 can be made
Voltage maintains 4.1V or so.
In another specific implementation mode, the suitable voltage of battery 140 may be a range.For example, working as battery
140 temperature be less than 43 DEG C when, as long as operating voltage be more than 4.1V be it is suitable, in this case, can be by battery 140
Be set greater than less than the corresponding voltage threshold of 43 DEG C of this temperature ranges or be equal to full voltage (4.45V as shown in Figure 3)
Value, as long as in this way, the voltage of battery 140 does not reach full voltage, mobile terminal 100 can always charge to battery 140 so that
It is operated under suitable voltage.In this case, the current voltage of battery 140, which finally differs, surely reaches the target electricity
Threshold value is pressed, but since the suitable services voltage of battery 140 is a range, is more than the range of 4.1V as the aforementioned, therefore, is led to
Method provided in this embodiment is crossed, the voltage for making the current voltage of battery 140 reach suitable under Current Temperatures is remained to.
