3014, electronic equipment calculates charge cycle number according to charging total amount.
Since battery could only discharge after charging, thus charge cycle number actually corresponds to the full charge of number of battery.Above process 3011-3014 is actually the process for calculating the fully charged number of battery namely the process of counting cell charging periodicity.
In counting cell charging periodicity, electronic equipment can be with the charging total amount of cumulative statistics battery, charging total amount can be indicated by the volume percent of battery, the charging total amount of battery can be 0 when leaving the factory, whenever accumulative charging total amount reaches 100%, i.e. when the volume percent of accumulative charging reaches 100%, it is believed that battery completes primary fully charged process, so as to a corresponding charging-discharging cycle.Thus, by the charging total amount that will add up divided by 100%, Available charge cycle number.That is, electronic equipment can be with according to the expression formula that charging total amount calculates charge cycle number are as follows:
N=Total/100% formula one

Due to the charge cycle number of battery in actual use, it is able to reflect the degree of aging of battery, thus electronic equipment can determine the corresponding first battery model parameter list of the first charge cycle number reference interval where charge cycle number, the target battery model parameter table as to match with the degree of aging of battery, so as to calculate the charge value of battery according to the parameter in matched target battery model parameter table.
Illustratively, when the standard configuration service life that certain battery provides is 500 charge cycles, table 2 is specifically as follows the form such as the following table 4.

For the corresponding relationship of charge cycle number reference interval and battery model parameter list shown in the table 4, electronic equipment determines that the process of the corresponding first battery model parameter list of the first charge cycle number reference interval where charge cycle number n can be as shown in Figure 4.
In this embodiment, electronic equipment can join according to charge cycle number, charge cycle number Between examination district and the corresponding relationship of battery model parameter list, the target battery model parameter table that quickly and intuitively the determining degree of aging with battery matches, so as to according to the parameter in matched target battery model parameter table, the accurate charge value for calculating battery.
Further, battery model parameter list can also include capacity growth rate reference value.Illustratively, the battery model parameter list including capacity growth rate reference value may refer to such as the following table 5.Wherein, the unit of capacity growth rate reference value can be mAh/0.1V.
Table 5
When battery model parameter list further includes capacity growth rate reference value, referring to Fig. 5, electricity value calculating method provided in an embodiment of the present invention can also include the following steps 304:
304, electronic equipment calculates the capacity growth rate of battery.
On the basis of step 304, electronic equipment determines that target battery model parameter table can specifically include from N number of battery model parameter list in step 302 according to charge cycle number:
3022, for electronic equipment according to charge cycle number, charge cycle number reference interval, capacity growth rate and capacity growth rate reference value determine target battery model parameter table from N number of battery model parameter list.
Wherein, capacity growth rate indicates during the charging process, when battery increases unit voltage, the capability value (the namely difference of Coulomb meter capacity count value) of corresponding increased battery.Under normal conditions, battery is longer using the time, and the internal resistance of cell is bigger, and for the capacity growth rate of battery with regard to smaller, the degree of aging of battery is also higher.Thus, the capacity growth rate of battery can be used for the degree of aging of reflection battery.Therefore, electronic equipment can consider the charge cycle number and capacity growth rate that are able to reflect cell degradation degree simultaneously, more accurately determine the target battery model parameter table to match with the degree of aging of battery.
Specifically, the capacity growth rate that electronic equipment in step 304, calculates battery may include:
3041, the first moment of electronic equipment during the charging process records the first voltage value of battery and the first capacity count value of Coulomb meter.
3042, the second moment of electronic equipment during the charging process records the second voltage value of battery and the second capacity count value of Coulomb meter.
3043, electronic equipment calculates capacity growth rate according to the first voltage value, the first capacity count value, second voltage value and the second capacity count value.
Specifically, when unit voltage is 0.1V, for electronic equipment according to the first count value and the second count value, the expression formula for calculating capacity growth rate can be with are as follows:
* 10 formula two of r=(CC2-CC1)/(V2-V1)
In above-mentioned formula two, r indicates capacity growth rate, and CC2 indicates the second capacity count value, and CC1 indicates the first capacity count value, and V2 indicates second voltage value, and V1 indicates the first voltage value.Wherein, the unit of the first capacity count value and the second capacity count value can be mAh, and the unit of the first voltage value and second voltage value can be V.
In one possible implementation, the first voltage value can be preset voltage value, at the time of the first moment can reach preset voltage value for the open-circuit voltage of battery；Second moment can be the charge cutoff moment, and second voltage value is blanking voltage.Wherein, at the charge cutoff moment, voltage possessed by battery is blanking voltage.Predeterminated voltage can be the voltage value near blanking voltage, and in the voltage segment limit close to blanking voltage, the capacity growth rate for calculating the battery of acquisition is more accurate.Illustratively, predeterminated voltage can be 4.2V, and blanking voltage can be 4.4V.
Wherein, the charge cutoff moment refers to, in battery charging process, electronic equipment determines that the capacity of battery reaches at the time of completely fill capacity.The charge cutoff moment of electronic equipment is not necessarily electronic equipment and at the time of charger disconnects, i.e. the charge cutoff moment of electronic equipment and charging stop timing is not identical concept.Specifically, the monitoring programme in electronic equipment can report charge cutoff message when battery charge cutoff, electronic equipment can determine that the moment is the charge cutoff moment.
Referring to Fig. 6, in above-mentioned steps 3022, electronic equipment is according to charge cycle number, charge cycle number reference interval, capacity growth rate and capacity growth rate reference value, determines that target battery model parameter table can specifically include following three kinds of situations from N number of battery model parameter list:
The first situation: the first charge cycle number reference interval where charge cycle number is corresponding In first battery model parameter list, the absolute value of the difference of the first capacity growth rate reference value and capacity growth rate is less than or equal to first threshold.In the case of this kind, step 3022 is specifically as follows following steps 401:
401, electronic equipment determines that the first battery model parameter list is target battery model parameter table.
When determining target battery model parameter table, electronic equipment can according to charge cycle number, this be able to reflect the parameter of cell degradation degree first, determines the corresponding first battery model parameter list of charge cycle number reference interval where charge cycle number.
For purposes of illustration only, the embodiment of the present invention is by with the N in table 1, for 5, the first battery model parameter list is the battery model parameter list T in table 13, battery model parameter list T3Corresponding charge cycle number reference interval is [200,300) to be illustrated for.
After determining the first battery model parameter list, when the first capacity growth rate reference value in the first battery model parameter list, when being less than or equal to first threshold with the absolute value for the difference for calculating the capacity growth rate obtained, it can illustrate that the corresponding first battery model parameter list of charge cycle number can be with the degree of aging accurate match of battery, thus electronic equipment can determine that the first battery model parameter list is target battery model parameter table.Wherein, the specific value of first threshold, which can according to need, is set, such as can be 5%.
When the absolute value of the first capacity growth rate reference value and the difference of capacity growth rate is greater than first threshold, it can be said that the charge cycle number of bright battery and the actual capacity growth rate of battery can not accurate match, target battery model parameter table can be determined according to the capacity growth rate of battery at this time.
Second situation: the absolute value of the difference of the first capacity growth rate reference value and capacity growth rate is greater than first threshold, and the first capacity growth rate reference value is greater than capacity growth rate.In the case of this kind, step 3022 is specifically as follows following steps 402:
402, the second battery model parameter list if it exists, the absolute value of the difference of the second capacity growth rate reference value and capacity growth rate that second battery model parameter list includes is less than or equal to first threshold, and second the corresponding second charge cycle number reference interval of battery model parameter list be greater than the first charge cycle number reference interval, then electronic equipment determines that the second battery model parameter list is target Battery model parameter list.
When the absolute value of the first capacity growth rate reference value and the difference for calculating the capacity growth rate obtained is greater than first threshold, and first capacity growth rate reference value be greater than capacity growth rate when, it can illustrate that capacity growth rate is more much smaller than the first capacity growth rate reference value, the practical degree of aging of battery degree of aging more corresponding than the first battery model parameter list is high.Thus, it is possible to the second battery model parameter list with the degree of aging accurate match of battery, it may be possible to the bigger battery model parameter list of charge cycle number in corresponding charge cycle number reference interval.
Therefore, electronic equipment can be from the charge cycle number in corresponding charge cycle number reference interval, in the bigger battery model parameter list of charge cycle number in charge cycle number reference interval more corresponding than the first battery model parameter list, a second battery model parameter list is determined whether there is, so that the absolute value of the difference of the second capacity growth rate reference value in the second battery model parameter list and capacity growth rate is less than or equal to first threshold.If it exists, then the second battery model parameter list is the target battery model parameter table for capableing of accurate match with the degree of aging of battery.Illustratively, as the battery model parameter list T that the first battery model parameter list is in table 13When, electronic equipment can sequentially determine battery model parameter list T3Battery model parameter list T later4And T5In, if there is the second battery model parameter list for meeting above-mentioned condition.
And, after determining that the second battery model parameter list is target battery model parameter table, the adjustable charging total amount of electronic equipment and charge cycle number, to adjust charge cycle number to the corresponding second charge cycle number reference interval of the second battery model parameter list, so that electronic equipment is subsequent quickly and accurately to determine target battery model parameter table according to charge cycle number adjusted.Specifically, if the corresponding second charge cycle number reference interval of the second battery model parameter list be [a, b), charge cycle number can be adjusted to boundary value a by electronic equipment, the arbitrary value that can also be adjusted to charge cycle number between (a, b).
When there is no the second battery model parameter list of the condition met in above-mentioned steps 402, can illustrate there is no than the first battery model parameter list more can accurate match battery degree of aging other battery model parameter lists, thus electronic equipment can execute above-mentioned steps 401, determine that the first battery model parameter list is target battery model parameter table.
The third situation: the first capacity growth rate reference value is absolute with the difference of capacity growth rate Value is greater than first threshold, and the first capacity growth rate reference value is less than capacity growth rate.In the case of this kind, step 3022 is specially following steps 403:
403, third battery model parameter list if it exists, the absolute value of the difference of third capacity growth rate reference value and capacity growth rate in third battery model parameter list is less than or equal to first threshold, and the corresponding third charge cycle number reference interval of third battery model parameter list is less than the first charge cycle number reference interval, it is determined that third battery model parameter list is target battery model parameter table.
When the absolute value of the first capacity growth rate reference value and the difference for calculating the capacity growth rate obtained is greater than first threshold, and first capacity growth rate reference value be less than capacity growth rate when, it can illustrate that capacity growth rate is more much larger than the first capacity growth rate reference value, the practical degree of aging of battery degree of aging more corresponding than the first battery model parameter list is low.Thus, it is possible to the third battery model parameter list with the degree of aging accurate match of battery, it may be possible to the smaller battery model parameter list of charge cycle number in corresponding charge cycle number reference interval.
Therefore, electronic equipment can be from the charge cycle number in corresponding charge cycle number reference interval, in the smaller battery model parameter list of charge cycle number in charge cycle number reference interval more corresponding than the first battery model parameter list, a third battery model parameter list is determined whether there is, so that the absolute value of the difference of the third capacity growth rate reference value in third battery model parameter list and capacity growth rate is less than or equal to first threshold.If it exists, then the third battery model parameter list is the target battery model parameter table for capableing of accurate match with the degree of aging of battery.Illustratively, as the battery model parameter list T that the first battery model parameter list is in table 13When, electronic equipment can sequentially determine battery model parameter list T3Battery model parameter list T before2And T1In, if there is the third battery model parameter list for meeting above-mentioned condition.
And, after determining that third battery model parameter list is target battery model parameter table, the adjustable charging total amount of electronic equipment and charge cycle number, to adjust charge cycle number to the corresponding third charge cycle number reference interval of third battery model parameter list, so that electronic equipment is subsequent quickly and accurately to determine target battery model parameter table according to charge cycle number adjusted.Specifically, if the corresponding second charge cycle number reference interval of the second battery model parameter list be [c, d), charge cycle number can be adjusted to boundary value c by electronic equipment, The arbitrary value that can be adjusted to charge cycle number between (c, d).
When there is no the third battery model parameter list of the condition met in above-mentioned steps 403, can illustrate there is no than the first battery model parameter list more can accurate match battery degree of aging other battery model parameter lists, thus electronic equipment can execute above-mentioned steps 401, determine that the first battery model parameter list is target battery model parameter table.
Further, after the above step 304, method provided in an embodiment of the present invention can also include:
305, when electronic equipment, this difference for calculating the capacity growth rate that the capacity growth rate obtained is obtained with last calculating is greater than second threshold, the total amount that will charge is reset.
Wherein, second threshold can be greater than first threshold, and the specific value of second threshold, which can be actually needed, to be set, such as second threshold can be 10%.Under normal conditions, with the increase of use time, the increase of charging-discharging cycle number, the capacity growth rate of battery is gradually reduced, when electronic equipment determines that this calculates the capacity growth rate of acquisition and the last difference for calculating the capacity growth rate obtained greater than second threshold, illustrate that the capacity growth rate of battery significantly increases, then electronic equipment may replace one piece of new battery, or the lower battery of degree of aging, and the charging total amount and charge cycle number currently saved in electronic equipment, the corresponding parameter of used batteries used before being, thus electronic equipment needs to reset the charging total amount of preservation, and add up charging total amount again, to according to again accumulative charging total amount, the corresponding charging-discharging cycle number of battery after calculating replacement.
Optionally, in above-mentioned steps 302, electronic equipment specifically, according to charge cycle number, can determine target battery model parameter table at the matching moment from N number of battery model parameter list.The specific time point at matching moment can be configured according to actual needs, so that electronic equipment will not influence the direct experience effect of user when the matching moment the upper battery model parameter list once loaded being switched to load target battery model parameter table.Optionally, the matching moment may include the booting moment, shutdown moment or charge cutoff moment of electronic equipment.
Furthermore, if the corresponding charge cycle number reference interval of the battery model parameter list currently loaded is [e, f), current charge cycle number is g, then when (g-f)/(f-e) is greater than third threshold value, it can illustrate charge cycle number and the matching status of battery model parameter list that currently loads numerous imbalances, electronic equipment may not matched for a long time and switch new target battery model parameter table, electronic equipment needs match new target battery model parameter table again as early as possible, so that the battery model parameter list of load is matched with the holding of the degree of aging of battery.At this point, the matching moment can also include the dormancy awakening moment of electronic equipment, so that electronic equipment can match new target battery model parameter table again at the dormancy awakening moment, and the direct experience effect of user will not influence.
Wherein, the specific value of third threshold value can be set according to actual needs, such as can be 30%.Illustratively, if the corresponding charge cycle number reference interval of the battery model parameter list currently loaded is [100,200), current charge cycle number is 240, then 240 and 200 difference is 40, [100,200) siding-to-siding block length is that the ratio of 200-100=100,40 and 100 is 40%, is greater than preset third threshold value 30%, thus at next dormancy awakening moment, electronic equipment can match again and load new target battery model parameter table.
In the electricity calculation method that the above embodiment of the present invention provides, electronic equipment combined charge periodicity and capacity growth rate, the target battery model parameter table to match with the degree of aging of battery can be more accurately determined, so as to accurately calculate the charge value of battery according to target battery model parameter table.
