Embodiment one
Fig. 1 is the flow chart of method for charging batteries embodiment one provided in an embodiment of the present invention, as shown in figure 1, this enforcement
The method for charging batteries of example, specifically may include steps of：
101st, battery is being carried out in n-th discharge process, the status data of collection battery, N is more than or equal to 1
Integer.
In the embodiment of the present invention, due to the difference of the difference of battery core own material, preparation technology, all have influence on battery just
Beginning performance.With being repeatedly charged to battery, discharge, the side reaction product in battery can gradually accumulate.Therefore, in battery
In the case that initial performance is difficult to change, to alleviate the polarization of battery core by way of adjusting rate of charge, thus improving battery
Cycle performance.
In embodiments of the present invention, by the way of constant-current charge, battery is charged, it should be noted that battery
One cycle includes once charging and once discharges.For example, the 10th circulation includes, and charges for the 10th time and the 10th electric discharge.Again
For example, the 100th circulation includes：Charge for 100th time and the 100th electric discharge.
Charging process refers to by the way of constant-current charge, battery is charged, and discharge process refers to battery to be made
With during electric discharge.Therefore, in embodiments of the present invention, by gathering status data in n-th discharge process for the battery,
Determine the state of battery battery when n-th is discharged, and then can determine whether that adjusting the N+1 time is charged for battery
When rate of charge.
For example, N is 5, then collection status data in n-th discharge process for the battery is that collection battery discharges in the 5th
During status data, rate of charge when charging for battery for the N+1 time is rate of charge when charging for battery for the 6th time.
Specifically, during a concrete implementation, status data can be DCIR (the Direct current of battery
Internal resistance, DC impedance) rate of increase.For example, DC impedance rate of increase can be put in the 1st time and n-th
In electric process, the change of DC impedance, n-th 50%DOD under 50%DOD (Deep of discharge, depth of discharge) state
DC impedance under state is Dn, and the DC impedance under the 1st 50%DOD state is D1, then DC impedance rate of increase is (Dn-
D1)/D1.
Additionally, status data can also be DC impedance of battery etc..
102nd, according to status data, determine rate of charge when charging for battery the N+1 time.
Collect battery after the status data of n-th, during a concrete implementation, comparison state can be passed through
Data and the relation of first threshold, in conjunction with the corresponding relation of first threshold and rate of charge, to determine the N+1 time and to charge for battery
When rate of charge.Wherein, first threshold can be to be set in advance according to different battery sizes from the corresponding relation of rate of charge
Fixed.
For example, battery is charged for battery using 1C multiplying power when charging for the 30th time, and battery, when discharging for 30 times, gathers
It is 5% to DC impedance rate of increase under 30%DOD state for the battery, according to the corresponding relation of status data and rate of charge
In, during DC impedance rate of increase 5% under 30%DOD state, reduce 0.1C rate of charge, then filled for battery for the 31st time
When electric, the rate of charge using 0.9C is charged for battery.
Collect battery after the status data of n-th, during a concrete implementation, can according to adjustment between
Every reducing rate of charge when charging for battery the N+1 time.Wherein, adjustment interval can be according to different battery sizes
Set in advance.
For example, battery is charged for battery using 2C multiplying power when charging for the 30th time, and battery, when discharging for 30 times, gathers
Be 5% to DC impedance rate of increase under 80%DOD state for the battery, first threshold is 2%, and adjustment is spaced apart 0.1C, then the
When being charged for battery for 31 times, the rate of charge using 1.9C is charged for battery.
It should be noted that in embodiments of the present invention, rate of charge when charging for battery for the N+1 time, both can adjust
Whole it is also possible to not adjust, it comes really according to the status data in the battery that battery is carried out, in n-th discharge process, collecting
Fixed.
103rd, when battery is carried out with the N+1 time charging, it is charged for battery using rate of charge.
In n-th battery discharge procedure, all can gather the status data of battery, to determine and to be filled for battery next time
Rate of charge when electric, to determine the need for the rate of charge of battery is adjusted.Therefore, adjustment is needed to fill when determining
During electric multiplying power, when being charged for battery for N+1 time, it is charged for battery using the rate of charge after adjustment.When determining
When not needing to adjust rate of charge, when being charged for battery for N+1 time, still entered for battery using the rate of charge of n-th
Row charges.
Method for charging batteries provided in an embodiment of the present invention, by carrying out in n-th discharge process to battery, collection electricity
The status data in pond, determines the state of battery, and then determines charging when charging for battery for the N+1 time according to this status data
Multiplying power, when being charged to battery for the N+1 time, is charged to battery using the rate of charge after adjustment, therefore, the present invention
The technical scheme providing, state when can be discharged each time according to battery, to adjust charging when next time charging for battery
Multiplying power, can extend the charging interval using the rate of charge after adjustment for battery charging, and then can mitigate the polarization phenomena of battery,
Improve the cycle performance of battery, and then the life-span of prolongation battery, solve using filling using constant current of the prior art
The mode that method for electrically is charged to battery, is easily reduced the cycle performance of battery, thus reducing the problem of battery life.
Embodiment two
Fig. 2 is the flow chart of method for charging batteries embodiment two provided in an embodiment of the present invention, as shown in Fig. 2 this enforcement
The method for charging batteries of example, specifically may include steps of：
201st, battery is being carried out in n-th discharge process, the status data of collection battery, N is more than or equal to 1
Integer.
202nd, judge that whether status data is more than first threshold, if so, execution step 203, if it is not, execution step 204.
In embodiments of the present invention, because the DC impedance rate of increase of battery can be affected by use environment, for example, electricity
The temperature of pond place environment, battery discharge depth etc., therefore, battery, in each discharge process, is required for the direct current to battery
Impedance rate of increase and first threshold are compared.Specifically, it is divided into two kinds of situations, Yi Zhongshi, DC impedance rate of increase is more than the
One threshold value, another kind is that DC impedance rate of increase is less than or equal to first threshold.
203rd, rate of charge when charging for the N+1 time, execution step 205 are reduced for battery.
When DC impedance rate of increase is more than first threshold, illustrate that battery has the situation of Accelerated polarization phenomenon, need to reduce
Rate of charge when next time charging for battery.For example, when discharging for the 100th time, the DC impedance rate of increase of battery is big for battery
In first threshold, then the 101st when being charged for battery, needs to reduce rate of charge.
During a concrete implementation, the mode reducing rate of charge when charging for the N+1 time for battery can be down to
Rare two kinds.
One way in which is to reduce rate of charge when charging for the N+1 time for battery according to rate of charge threshold value, specifically
Ground, rate of charge threshold value can be set according to the battery of different model.For example, set rate of charge threshold value as 0.05C, the
When charging for battery for 200 times, using 0.9C multiplying power, then in the 200th primary cell discharge process, the DC impedance rate of increase that collects
More than first threshold, then using the multiplying power of 0.85C when being charged for battery for the 201st time.
Another way is, according to the corresponding relation of status data and rate of charge, when reduction is charged for battery for the N+1 time
Rate of charge.Specifically, status data and the corresponding relation of rate of charge can be set according to the battery of different model.
For example, set first threshold as 3%, DC impedance rate of increase is that when 5%, corresponding rate of charge is 0.8C, and DC impedance increases
Rate is that when 10%, corresponding rate of charge is 0.6C, when charging for battery for the 300th time, using 0.9C multiplying power, then the 300th primary cell
In discharge process, the DC impedance rate of increase collecting is 5%, more than first threshold, then when being charged for battery for the 301st time
Using the multiplying power of 0.8C, if in the 300th primary cell discharge process, the DC impedance rate of increase that collects is 11%, then the 301st
Secondary when being charged for battery using the multiplying power of 0.6C.
204th, the rate of charge of N+1 primary cell is identical with the rate of charge of the battery of n-th, execution step 206.
When DC impedance rate of increase is less than or equal to first threshold, illustrates that battery is normal and fill it is not necessary to reduce battery
Rate of charge when electric, that is, the rate of charge of N+1 primary cell is identical with the rate of charge of the battery of n-th.For example, battery exists
During the 100th electric discharge, the DC impedance rate of increase of battery is less than first threshold, then the 101st when being charged for battery, using the
Rate of charge when being charged for battery for 100 times.
205th, when battery is carried out with the N+1 time charging, the use of the rate of charge after reducing is that battery charges.
206th, when battery is carried out with the N+1 time charging, the rate of charge using n-th is that battery charges.
Method for charging batteries provided in an embodiment of the present invention, by carrying out in n-th discharge process to battery, collection electricity
The DC impedance rate of increase in pond, determines the state of battery according to DC impedance rate of increase, and then determination is filled for battery for the N+1 time
Rate of charge when electric, when being charged to battery for the N+1 time, is charged to battery using the rate of charge after adjustment,
Therefore, the technical scheme that the present invention provides, state when can be discharged each time according to battery, to adjust and to fill for battery next time
Rate of charge when electric, can extend the charging interval using the rate of charge after adjustment for battery charging, and then can mitigate battery
Polarization phenomena, improve the cycle performance of battery, and then extend the life-span of battery, solve using of the prior art using permanent
Determine the mode that the charging method of electric current is charged to battery, be easily reduced the cycle performance of battery, thus reducing battery life
Problem.

302nd, when status data is more than Second Threshold, stop being charged for battery.
Because battery is in the case that polarization phenomena are serious, it is continuing with larger rate of charge and is charged for battery
When, battery easily burns or explodes.Therefore, in order to ensure the safety of battery, set the second threshold in embodiments of the present invention
Value, Second Threshold can be understood as the limit that battery has reached the life-span, needs to change in time battery.Therefore, implement in the present invention
In example, Second Threshold is more than first threshold.
When the DC impedance rate of increase of battery is more than Second Threshold, illustrates that battery has reached the limit in life-span, then need
Stop being charged for battery.
For example, when battery is in terminal, the DC impedance rate of increase of the battery collecting is more than Second Threshold, then terminal
It is impossible to be charged to battery after connection charger, then user is known that the life-span of this battery to reach capacity, and can carry out
Change battery.
Again for example, when battery is in electric automobile, the DC impedance rate of increase of the battery collecting is more than Second Threshold,
Then it is impossible to be charged to battery after electric automobile connection charging gun, then user is known that the life-span of this battery to reach pole
Limit, can carry out changing battery.

Because battery is in the case that polarization phenomena are serious, it is continuing with larger rate of charge and is charged for battery
When, battery easily burns or explodes, in the case that battery has burning or blast, can to the things of battery ambient and
User causes certain harm.Therefore, in embodiments of the present invention, can be pointed out by way of outputting alarm signal, should
Battery has certain danger now.
During a concrete implementation, warning signal can be Word message, acoustical signal or voice signal etc..
During a concrete implementation, send warning signal main body can battery be located main body send.
For example, when the battery in terminal has danger, warning signal can be sent by terminal.Again for example, the battery in electric automobile
When there is danger, warning signal can be sent by electric automobile.
