The charging method provided based on above-described embodiment one, the embodiment of the present invention is in S102, according to the state of battery core
Information, it may be judged whether meet the condition of charge parameter adjusting battery core, the step for implementation be specifically described.
In the embodiment of the present invention, according to the status information of battery core, it may be judged whether meet the bar of the charge parameter adjusting battery core
Part, can include but not limited to following two specific implementation.
The first: is in the embodiment of the present invention, if the status information of battery core is the current capacities of battery core, current according to battery core
Capacity, it may be judged whether the specific implementation of the condition meeting the charge parameter adjusting battery core can include but not limited to lower section
Formula 1 and mode 2 two kinds:
Mode 1: the current capacities of the battery core got is compared with the capacity threshold preset, if the current appearance of battery core
Amount, less than or equal to capacity threshold, determines the condition meeting the charge parameter adjusting battery core.Or, if the current capacities of battery core
More than capacity threshold, determine the condition being unsatisfactory for adjusting the charge parameter of battery core.
Concrete, in the embodiment of the present invention, the capacity threshold of battery core is less than or equal to the initial capacity of battery core, therefore,
Can carry out presetting the capacity threshold of battery core the most according to actual needs, this is not carried out especially by the embodiment of the present invention
Limit.
Hereinafter the specific implementation of the capacity threshold of default battery core is specifically described.
Concrete, when presetting the capacity threshold of battery core, a capacity threshold set can be preset, this capacity threshold set can
To include but not limited at least one capacity threshold, this is not particularly limited by the embodiment of the present invention.
If the capacity threshold set preset includes at least two capacity threshold, the capacity threshold in this capacity threshold set
Numerical values recited can be identical, or, the numerical values recited of the capacity threshold in this capacity threshold set can also be different, and the present invention is real
Execute example this is not particularly limited.
If it should be noted that capacity threshold set includes at least two capacity threshold, if in this capacity threshold set
There is the capacity threshold that n numerical value is different, just have the condition meeting the charge parameter of corresponding adjustment battery core n time, and then, so that it may
Carrying out n time with the charge parameter to battery core to adjust, wherein, n is the integer more than 0.
For example, it is assumed that capacity threshold set includes at least two capacity threshold, if the capacity in this capacity threshold set
The numerical values recited of threshold value is identical, then be equivalent to preset 1 capacity threshold, the charge parameter of battery core can only carry out 1 time and adjust.
Or, again for example, it is assumed that capacity threshold set includes at least two capacity threshold, if the capacity threshold in capacity threshold set
Numerical values recited different, it is assumed that have 5 different capacity thresholds, then the charge parameter of battery core can be carried out 5 times and adjust.
Or, again for example, it is assumed that capacity threshold set includes 4 capacity thresholds, it is assumed that 4 capacity thresholds have 3 capacity thresholds
Numerical value identical, i.e. this capacity threshold set includes the capacity threshold that 2 numerical value is different, then can be to the charge parameter of battery core
Carry out 2 times to adjust.
During a concrete implementation, if the numerical values recited of the capacity threshold in the capacity threshold set preset is not
With, then can be that each capacity threshold carries out descending sequence according to numerical values recited, and the current of the battery core got is held
Amount successively with sequence after capacity threshold compare.
It is concrete, if the current capacities of battery core that gets of n-th is less than or equal to after n-th capacity threshold, the most now
Determine the condition of the charge parameter meeting the adjustment battery core preset；And owing to the current capacities of battery core is the trend being gradually lowered,
The current capacities that the current capacities of the battery core got for the N+1 time necessarily gets less than or equal to n-th, i.e. the N+1 time
The current capacities of the battery core got is necessarily less than or equal to n-th capacity threshold；So, according to getting for the N+1 time
When the current capacities of battery core judges whether to meet the regularization condition preset, need the current appearance of the battery core got the N+1 time
Amount compares with the N+1 capacity threshold.Wherein, it is that each capacity threshold carries out descending sequence according to numerical values recited
After, the numerical value of n-th capacity threshold is more than the numerical value of N+1 capacity threshold, and N is the integer more than 0.
Concrete, if the current capacities of battery core that n-th gets is more than n-th capacity threshold, the most now determine discontented
The condition of the charge parameter of the adjustment battery core that foot is preset；And owing to the current capacities of battery core is the trend being gradually lowered, the N+1 time
The current capacities that the current capacities of the battery core got necessarily gets less than or equal to n-th, gets for i.e. the N+1 time
The current capacities of battery core and the relation of n-th capacity threshold are the most uncertain；So, in the battery core got according to the N+1 time
When current capacities judges whether to meet the regularization condition preset, need the current capacities of battery core that gets the N+1 time still
Compare with n-th capacity threshold.
Illustrating, if having preset a capacity threshold set, this capacity threshold set includes that three numerical value are different
Capacity threshold, is 1700mAh, 1900mAh, 1800mAh respectively, during the whole recycling of battery core, can be this electricity
Core carries out the adjustment of 3 charge parameters.Should carry out according to numerical value is descending for three capacity thresholds in capacity threshold set
Sequence, obtaining ranking results is 1900mAh > 1800mAh > 1700mAh.The current capacities of battery core that then can will obtain, according to
The order of above-mentioned sequence compares with these three capacity threshold respectively.
If the current capacities of the battery core got for the first time is 1850mAh, then by current capacities 1850mAh first with capacity
Threshold value 1900mAh compares, it is known that, current capacities 1850mAh is less than capacity threshold 1900mAh, meets and adjusts filling of battery core
The condition of electrical quantity.
If the current capacities of the battery core that second time gets is 1820mAh, it is known that, the current appearance of the battery core now got
Amount is certain less than the current capacities 1850mAh got for the first time, i.e. the current capacities 1820mAh of the battery core that second time gets
Less than first capacity threshold 1900mAh.The current capacities of the battery core owing to getting for the first time has been expired when being 1850mAh
Foot adjusts the condition of the charge parameter of battery core, and is adjusted the charge parameter of battery core, now, and the current appearance that will get
Amount 1820mAh and second capacity threshold 1800mAh compares, it is known that, current capacities 1820mAh is more than capacity threshold
1800mAh, is unsatisfactory for adjusting the condition of the charge parameter of battery core.
If the current capacities of the battery core that third time gets is 1780mAh, it is known that, the current appearance of the battery core now got
The current capacities 1820mAh that amount 1780mAh gets less than second time, and the current capacities 1820mAh that second time gets is also
It is unsatisfactory for adjusting the condition of the charge parameter of battery core, the current capacities 1780mAh of the battery core got i.e. for the third time and second
The relation of capacity threshold 1800mAh is the most uncertain；Now, then by the current capacities 1780mAh got and second capacity threshold
Value 1800mAh compares, it is known that, current capacities 1780mAh is less than capacity threshold 1800mAh, meets the charging adjusting battery core
The condition of parameter.
During another concrete implementation, if the numerical values recited phase of the capacity threshold in the capacity threshold set preset
With, be equivalent to preset 1 capacity threshold, during the whole recycling of battery core, can be that this battery core carries out 1 charging
The adjustment of parameter.Concrete, when being less than or equal to this unique capacity threshold for the first time according to the capacity of current battery core, determine
Meet the condition of the charge parameter adjusting battery core；And during cycle life later, there is not the appearance that other numerical value are different
Amount threshold value, no longer meets the condition of the charge parameter adjusting battery core.
Illustrating, if having preset a capacity threshold set, three capacity thresholds in this capacity threshold set are respectively
It is 1800mAh, 1800mAh, 1800mAh, now, is equivalent to preset 1 capacity threshold 1800mAh, then gets all
Current capacities and the capacity threshold 1800mAh of battery core compare and i.e. can determine whether to meet the condition preset.Wherein, N is
Integer more than 0.
If the current capacities of the battery core that n-th gets is 1820mAh, then by the current capacities of the battery core of acquisition
1820mAh compares with the capacity threshold 1800mAh preset, and determines the condition being unsatisfactory for adjusting the charge parameter of battery core；
If the current capacities of the battery core got for the N+1 time is 1700mAh, then by the current capacities of the battery core of acquisition
1700mAh compares with the capacity threshold 1800mAh preset, and determines the condition meeting the charge parameter adjusting battery core.
Afterwards, if the current capacities of the battery core got for the N+2 time is 1600mAh, though the current appearance of the battery core obtained
Amount 1600mAh is less than the capacity threshold 1800mAh preset, but there are not other capacity that capacity threshold 1800mAh numerical value is different
Threshold value, the most no longer meets the condition of the charge parameter adjusting battery core.
Mode 2: according to the current capacities of battery core, determines the capability retention of battery core, then, the capability retention that will determine
Compare with default capability retention threshold value, if the capability retention of battery core is less than or equal to capability retention threshold value,
Determine the condition meeting the charge parameter adjusting battery core.Or, if the capability retention of battery core is more than capability retention threshold value, really
Surely it is unsatisfactory for adjusting the condition of the charge parameter of battery core.
Illustrate, it is assumed that the capability retention threshold value preset is 80%.If the capability retention of the battery core got is
77%, the capability retention of the battery core got is compared with the capability retention threshold value preset, the capacity of battery core keeps
Rate 77%, less than the capability retention threshold value 80% preset, determines the condition meeting the charge parameter adjusting battery core.Or, example again
As, if the capability retention of the battery core got is 85%, by the current capacities conservation rate of battery core got and the appearance preset
Amount conservation rate threshold value compares, and the capability retention 85% of battery core, more than the capability retention threshold value 80% preset, determines not
Meet the condition of the charge parameter adjusting battery core.
Similar with the specific implementation of the capacity threshold of default battery core, during a concrete implementation, preset electricity
During the capability retention threshold value of core, the capability retention threshold value of a battery core can be preset, it is also possible to preset a capacity and keep
Rate threshold value set, this capability retention threshold value set can include but not limited to the capability retention threshold value of at least two battery core,
This is no longer repeated by the embodiment of the present invention.
The second: in the embodiment of the present invention, if the current resistance that the status information of battery core is battery core, current according to battery core

Formula 3 and mode 4 two kinds:
Mode 3: the current resistance of the battery core got is compared with the resistance threshold preset, if the current electricity of battery core
Resistance, more than or equal to resistance threshold, determines the condition meeting the charge parameter adjusting battery core.Or, if the current resistance of battery core
Less than resistance threshold, determine the condition being unsatisfactory for adjusting the charge parameter of battery core.
Concrete, in the embodiment of the present invention, the capacity resistance of battery core is more than or equal to the initial resistance of battery core, therefore,
Can carry out presetting the capacity threshold of battery core the most according to actual needs, this is not carried out especially by the embodiment of the present invention
Limit.
Similar with the specific implementation of the capacity threshold of default battery core, during a concrete implementation, preset electricity
During the resistance threshold of core, the resistance threshold of a battery core can be preset, it is also possible to preset a resistance threshold set, this resistance threshold
Value set can include but not limited to the resistance threshold of at least two battery core, and this is no longer repeated by the embodiment of the present invention.
Mode 4: according to the current resistance of battery core, determines the resistance rate of increase of battery core, then, the resistance rate of increase that will determine
Compare with default resistance rate of increase threshold value, if the resistance rate of increase of battery core is more than or equal to resistance rate of increase threshold value,
Determine the condition meeting the charge parameter adjusting battery core.Or, if the resistance rate of increase of battery core is less than resistance rate of increase threshold value, really
Surely it is unsatisfactory for adjusting the condition of the charge parameter of battery core.
Illustrate, it is assumed that the resistance rate of increase threshold value preset is 120%.If the resistance rate of increase of the battery core got is
125%, the resistance rate of increase of the battery core got is compared with the resistance rate of increase threshold value preset, the resistance of battery core increases
Rate 125%, more than the resistance rate of increase threshold value 120% preset, determines the condition meeting the charge parameter adjusting battery core.Or, again
Such as, if the resistance rate of increase of the battery core got is 110%, by the current resistance rate of increase of battery core that gets with preset
Resistance rate of increase threshold value compares, and the resistance rate of increase 110% of battery core is less than the resistance rate of increase threshold value 120% preset, really
Surely it is unsatisfactory for adjusting the condition of the charge parameter of battery core.
Similar with the specific implementation of the capacity threshold of default battery core, during a concrete implementation, preset electricity
During the resistance rate of increase threshold value of core, the resistance rate of increase threshold value of a battery core can be preset, it is also possible to preset a resistance and increase
Rate threshold value set, this resistance rate of increase threshold value set can include but not limited to the resistance rate of increase threshold value of at least two battery core,
This is no longer repeated by the embodiment of the present invention.
It should be noted that when the current resistance of the current capacities that status information is battery core of battery core and battery core, permissible

Selecting other candidate's rate of charge rate of charge as the battery core after reducing of rate of charge C4, this is not entered by the embodiment of the present invention
Row is particularly limited to.
Or, again for example, it is possible to preset the rate of charge candidate collection of battery core, this voltage set can include at least one
Individual candidate's rate of charge, such as C1, C2 ... Cn, and is carried out by greatly for the candidate's rate of charge in this rate of charge candidate collection
To little sequence, if C7 > C3 > C5 > ... Cn, then, when determining the condition meeting the charge parameter adjusting battery core, reduce electricity
The rate of charge of core can select candidate's rate of charge in rate of charge candidate collection to make according to this ranking results successively
Rate of charge for the battery core after reducing.If rate of charge now is C3, after use after a while, detect and full
Foot adjusts the condition of the charge parameter of battery core, then select candidate's charging times in this rate of charge candidate collection according to this ranking results
After rate C3, the candidate rate of charge C5 of is as the rate of charge after reducing.
Or, again for example, it is possible to preset the rate of charge candidate collection of battery core, this rate of charge candidate collection can be wrapped
Include at least one candidate's rate of charge, such as C1, C2 ... Cn, and determine C1, C2, the numerical values recited relation of C3 ... Cn are
C1 > C2 > C3 > ... Cn, now, then when the condition of charge parameter of satisfied adjustment battery core, can be according to C1, C2, C3 ... Cn
Order carry out the reduction of rate of charge of battery core, now, be equivalent to be provided with appointment for the rate of charge lowering battery core every time
Numerical value.
It is understood that the numerical values recited order of the candidate's rate of charge in the rate of charge candidate collection of battery core, can
Being fixing, it is also possible to be unfixed.Such as, rate of charge candidate collection can be C1 > C2 > C3 > ... Cn, it is possible to
To be C3 > C5 > C2 > ... Cn etc., this is not particularly limited by the embodiment of the present invention, in the embodiment of the present invention, simply by electricity
The rate of charge candidate collection of core is less than candidate's rate of charge of rate of charge of current battery core as the electricity after reducing
The rate of charge of core.

Concrete, interval delta V can be adjusted with predeterminated voltage, Δ V is in order to represent two charge cutoff voltages of adjacent battery core
Between difference.It is understood that Δ V can include but not limited at least one numerical value.Then when determining satisfied adjustment battery core
The condition of charge parameter, the charge cutoff voltage reducing battery core can realize by the way of current voltage deducts Δ V.
Illustrate, if having preset Voltage Cortrol interval delta V1, Δ V2 ... Δ Vn-1, the then voltage difference between V1 and V2
Value is Δ V1, and V1 can deduct the magnitude of voltage magnitude of voltage as V2 of Δ V1；Difference between V2 and V3 is Δ V2, can be by
V2 deducts the magnitude of voltage magnitude of voltage as V3 of Δ V2；By that analogy, charge cutoff voltage V1, V2 of battery core are obtained ... Vn.
Or, the most such as, if having preset Voltage Cortrol interval delta V=Δ V1=Δ V2=... Δ Vn-1, then Vn-1 with
Difference between Vn is Δ V, and V1 can deduct the magnitude of voltage magnitude of voltage as V2 of Δ V, and the magnitude of voltage that V2 deducts Δ V is made

The environment of battery core or battery core changes, and some reasons being likely to occur, it is also possible to select to be less than in this candidate collection
Other candidate's voltages of candidate voltage V4 are as the charge cutoff voltage of the battery core after reducing, and this is not carried out by the embodiment of the present invention
It is particularly limited to.
Or, again for example, it is possible to preset the charge cutoff voltage candidate collection of battery core, this charge cutoff voltage candidate collection
In can include at least one candidate's voltage, such as V1, V2 ... Vn, and carry out size for the candidate's voltage in this candidate collection
Sequence, if V7 > V3 > V5 > ... Vn, then when determining the condition meeting the charge parameter adjusting battery core, reduce the charging of battery core
Blanking voltage can select candidate's voltage in charge cutoff voltage candidate collection as reduction according to ranking results successively
After the charge cutoff voltage of battery core.If charge cutoff voltage now is V3, after use after a while, determine and full
Foot adjusts the condition of the charge parameter of battery core, then select candidate's voltage in this charge cutoff voltage candidate collection according to ranking results
After V3, the candidate voltage V5 of is as the charge cutoff voltage after reducing.
Or, again for example, it is possible to preset battery core charge cutoff voltage candidate collection, this voltage set can include to
Few candidate's voltage, such as V1, V2 ... Vn, and determine V1, V2, the numerical values recited relation of V3 ... Vn are V1 > V2 > V3
> ... Vn, now, then meet, when use data battery core being detected, the condition of charge cutoff voltage of battery core of reducing, can be by
Carry out the reduction of the charge cutoff voltage of battery core according to V1, V2, the order of V3 ... Vn, now, be equivalent to as lowering battery core every time
Charge cutoff voltage be provided with appointment numerical value.
It is understood that the numerical values recited order of the candidate's voltage in the charge cutoff voltage candidate collection of battery core, can
Being fixing, it is also possible to be unfixed.Such as, charge cutoff voltage candidate collection can be V1 > V2 > V3 > ... Vn,
Can also be V3 > V5 > V2 > ... Vn etc., this is not particularly limited by the embodiment of the present invention, in the embodiment of the present invention, simply
Using in the charge cutoff voltage candidate collection of battery core less than candidate's voltage of charge cutoff voltage of current battery core as fall
The charge cutoff voltage of the battery core after low.
During a concrete implementation, the charge cutoff voltage V1 preset can be the charging critical voltage of battery core,
