Embodiment one
In order to avoid unreasonable for the charging modes of battery charging in prior art, and when charging for battery
The problem that charge efficiency is relatively low, the embodiment of the present invention one proposes the charging method of a kind of battery, the most such as
Shown in Fig. 1, the energy that described method can be applicable to use vehicle to produce when braking or idling is that battery fills
In the scene of electricity, prestore the different SOC under different temperatures in difference charging duration and charging current
Several corresponding relations, when charging for described battery, described method can comprise the following steps that
Step 101, obtains temperature and the SOC of described battery, and filling when being charged for described battery
Electricity duration.
Concrete, temperature, SOC and charging duration can determined according to the corresponding relation prestored
After, determine the charging current of battery, wherein charging duration refers to be continued in time starting and charge by battery
Time.
Owing to charging current is to have relation with temperature, SOC and charging duration, again because of according to storage right
Should be related to and understand the corresponding different charging currents of charging duration different at a certain temperature and a certain SOC,
It is thus desirable to obtain temperature and the SOC of battery.
In the case of determining in temperature and SOC, charging durations different when charging for battery is corresponding
Charging current is different, therefore also needs to the charging duration determined when being charged for battery, to enter
One step determines the charging current of battery, and further, charging duration when being charged for battery refers to
Start the difference between time when charging for battery and current time, wherein charge residing for duration and battery
Temperature and SOC unrelated, the most whether corresponding relation changes, a length of beginning during the charging of acquisition
The difference between time and current time when charging for battery, such as: temperature be 10 DEG C, SOC
Starting under the state being 10% to be charged for battery, now during charging a length of 0, corresponding relation is first right
Should be related to, after charging process continue for 30 seconds, temperature become 20 DEG C, SOC be 20%, then now
Charging time a length of 30 seconds, now corresponding relation changes, i.e. corresponding relation becomes the second corresponding relation,
A length of 20 DEG C, 20% and 30 seconds when the temperature, SOC and the charging that so obtain, and with this temperature, SOC
It is defined as the second corresponding relation with the relation of charging duration.
Step 102, according to described temperature, described SOC and described charging duration, determines the first corresponding pass
System.
Concrete, the parameter owing to comprising in corresponding relation has 4: temperature, SOC, charging duration and fill
Electricity electric current, is assured that out corresponding corresponding relation, i.e. after determining temperature, SOC, charging duration
When after 3 parameter determinations in a corresponding relation, then i.e. can determine that the 4th ginseng according to corresponding relation
Number, therefore after temperature, SOC and charging duration determine, then this temperature, SOC and charging duration place
Corresponding relation also determine that.
Further, the charging duration at this temperature and this SOC can convert, along with charging duration
Growth, i.e. charging duration constantly become big, then the corresponding relation determined the most just there occurs change,
The charging current that corresponding relation is determined after changing the most just changes, further, in temperature and
When SOC is definite value, charging current changes along with the change of charging duration, and needs to obtain in real time
A certain temperature and a certain SOC constant in the case of charging duration, to determine charging current.
Step 103, according to described first corresponding relation, determines charging current.
Concrete, after determining corresponding relation, charging current i.e. well-determined, and should
Charging current determines according to practical situation, not only can ensure that charge efficiency but also can use reasonably charging
Electric current is battery charging.
Step 104, is that described battery is charged according to described charging current.
The described charging current that charging current when charging for described battery not higher than determines.
Concrete, in order to ensure charge efficiency, and do not damage the principle of battery, the charged electrical determined
Flow by the maximum charging current allowed under present case, naturally it is also possible to select less than this charging current value
Charging current be battery charging.
Owing at a certain temperature and a certain SOC, the charging interval can be continuously increased, along with the increasing of charging duration
Adding, in SOC and temperature, at least one parameter can change, i.e. at least one parameter in temperature and SOC
Numerical value can increase, after temperature after determining change and SOC, the temperature after needing according to change and SOC
Redefine charging current for battery down, therefore, be that described battery fills according to described charging current
After electricity, described method also includes:
Judge in described temperature and described SOC, whether at least one parameter changes；
If in described temperature and described SOC, at least one parameter changes, it is judged that the ginseng changed
Whether the numerical value of number exceedes threshold value；
If described numerical value exceedes described threshold value, obtain the current temperature of described battery and current SOC；
According to described Current Temperatures, described current SOC and described charging duration, determine the second corresponding relation；
According to described second corresponding relation, determine current charging current；
It is that described battery is charged according to described current charging current.
Concrete, after according to certain charging current being battery charging, in the temperature of battery and SOC at least
One parameter also can change therewith, if the numerical value of the parameter after Bian Hua exceedes threshold value, if continuing to make
It is irrational for charging for battery by charging current before, and also influences whether charge efficiency, because of
This is after in temperature and SOC, at least one parameter changes, and the numerical value of the parameter changed exceedes
During threshold value, it is thus necessary to determine that go out the temperature after change and SOC, and the charging being currently charged for battery
Duration, such as: when charging when varying more than threshold value of temperature and SOC a length of 10 seconds, then then base
When charging, temperature and SOC behind a length of 10 seconds, and change determine corresponding relation, are determining change
After temperature, SOC after change and charging duration after, can close according to above-mentioned 3 parameter determination correspondences
System, and then determine charging current.
Further, either in temperature, SOC and the charging duration at a certain temperature and a certain SOC
Parameter values after any one Parameters variation all can cause the change of charging current after exceeding certain value,
And causing the reason of this change is to have preset temperature, SOC, charging duration and the corresponding relation of charging current,
When temperature, SOC and one of them parameter of charging duration change, then finally all can cause charging
The change of electric current, when in temperature and SOC, at least one parameter changes, it is thus necessary to determine that after going out change
Temperature, SOC after change and charging duration finally determine charging current, and at temperature and SOC
In the case of constant, need constantly to change corresponding relation according to charging duration, determine charging current.
Wherein, the matching principle of 4 parameters includes: in temperature in several corresponding relations described of storage
Time identical with SOC, the charging the biggest then charging current of duration is the least；Several corresponding relations described of storage
In charge duration identical with SOC time, the highest then charging current of temperature is the biggest；Storage described several
In corresponding relation when temperature is identical with charging duration, SOC is the biggest, and then charging current is the least；The institute of storage
Between the time between the charging duration stated in several corresponding relations under different temperatures and/or different SOC
Every identical or different.
Concrete, ensureing not damage battery, and in the case of charge efficiency can being increased, above-mentioned 4
The coupling numerical value of individual parameter can determine according to practical situation, but the numerical value matched to meet above-mentioned wanting
Ask.
Such as: the corresponding relation with same temperature and same SOC can be deposited by the form of form
Storage, the most as shown in Table 1 and Table 2:
Table 1
Table 2
In the corresponding relation of Tables 1 and 2 when temperature is identical with SOC, charge the biggest then charged electrical of duration
Flowing the least, further, when temperature is identical with SOC, the charging the least then charging current of duration is the biggest.
Based on table 1, in the case of the charging interval is identical with SOC, the highest then charging current of temperature
The biggest, the concrete corresponding relation formed is as shown in table 3:
Table 3
When temperature is identical with charging interval section, SOC is the biggest, and then charging current is the least, and specifically formed is right
Should be related to as shown in table 4:
Table 4
In several corresponding relations of storage, if temperature is identical, between the time of SOC and charging duration
Every Changing Pattern identical, several corresponding relations can be stored with the form of table 4, if warm
Degree changes, but the Changing Pattern of the time interval of SOC and charging duration is constant, and it is right to be formed
Answer relation table as shown in table 5:
Table 5
If SOC is identical with the Changing Pattern of the time interval of charging duration, corresponding filling under different temperatures
Electricity electric current can store in the way of as shown in table 4 and table 5, if the time interval of charging duration
Changing Pattern differ, then can according to the Changing Pattern of temperature and/or SOC by corresponding relation store
Become form, naturally it is also possible to storing with single corresponding relation, concrete storage mode is according to reality
Border situation determines.
The energy used when charging for described battery includes: the vehicle of storage produces in braking or idling process
Raw gross energy；Or, the energy that vehicle produces during braking or idling in real time.
Concrete, in order to ensure that energy is not wasted, can first vehicle be produced in braking or idling process
Raw energy stores, then by energy conversion device, the gross energy after storage is converted to electric energy storage
In battery；In order to ensure as quickly as possible convert energy into electric energy, can produce in car braking or idling
During raw energy, the energy of generation being converted to electric energy the most at once, which kind of conversion regime specifically used can basis
Practical situation selects, and storing process as shown in said method, this is no longer going to repeat them.
Temperature according to the battery obtained and SOC in the embodiment of the present invention, and fill for described battery
Charging duration during electricity determines corresponding relation, is then determining charging current according to this corresponding relation, with
Be that battery is charged according to this charging current, in the embodiment of the present invention due to storage be under different temperatures
Different SOC at the corresponding relation of difference charging duration and charging current, thus determine that charging current
Size relevant with temperature, SOC and charging duration, further, when temperature and SOC mono-timing, fill
Electricity electric current changes along with the change of charging duration, and therefore using the charging current determined is battery charging
Time charging modes more reasonable, and charge efficiency when charging for battery is higher.
In order to the technological thought of the embodiment of the present invention is expanded on further, in conjunction with concrete application scenarios, right
The technical scheme of the embodiment of the present invention illustrates, concrete, stores above-mentioned 4 ginsengs the most in a device
The corresponding relation of number, and current temperature is 20 DEG C, icon such as table 5 institute that corresponding relation is formed, and
Obtain SOC be 15%, then if battery charging charging interval t≤t1 time, then use 240
The charging current of peace is battery charging, and along with the increase in charging interval, but temperature and the number of SOC
When value is not above threshold value, and charging interval t1 ＜ t≤t2 now, then now use 160 peaces
Charging current be battery charging, if over the increase in charging interval, temperature and SOC numerical value always
When being not above threshold value, then the interval corresponding charging current using charging duration place is that battery is carried out
Charging, if after charging duration is more than t5, then the charging current of 8 peaces is battery charging the most always.
During charging for battery, if at least one parameter changes in temperature and SOC, and
After the numerical value of the parameter changed exceedes threshold value, then determine according to the corresponding relation place form after change
Charging current, such as: if the threshold value of SOC is set as that 20%, 40%, 60%, 80%, 100% currently obtains
SOC in the range of 0～20%, then determine charging current according to the corresponding relation of 20%SOC；If currently obtaining
The SOC taken in the range of 20～40%, then determines charging current according to the corresponding relation of 40%SOC, with this
Analogize；And temperature is too, such as: the threshold value of temperature can be set as 10 DEG C, 20 DEG C, 30 DEG C,
40 DEG C, when temperature is between 10 DEG C～20 DEG C, determine charging current according to the corresponding relation of 10 DEG C, if working as
When the temperature of front acquisition is between 20 DEG C～30 DEG C, determine charging current according to the corresponding relation of 20 DEG C, with
This analogizes.
Such as: if when SOC rises to 35% from 15% in charging process, but temperature does not become
Changing, then it needs to be determined that go out at 40%SOC, the charging duration that temperature has been carried out in the case of being 20 DEG C is true
Determining charging current, at 40%SOC, during the charging that temperature has been carried out in the case of being 20 DEG C, a length of battery exists
20%SOC, the charging duration that temperature has been carried out in the case of being 20 DEG C, if battery is in 20%SOC, temperature
A length of t during the charging carried out in the case of being 20 DEG C, and t1 ＜ t≤t2, then during the charging of acquisition
Length is also t, and t1 ＜ t≤t2, and therefore according to the 40%SOC obtained, temperature is 20 DEG C, and charging
The corresponding relation that duration t1 ＜ t≤t2 determines, the charging current now using 120 peaces is battery charging,
If over the increase in charging interval, but when the numerical value of temperature and SOC never exceedes threshold value, that
The interval corresponding charging current using charging duration place is that battery is charged, if charging duration
After t5, then the charging current of 6 peaces is battery charging the most always.
If temperature changes but the numerical value after SOC change never exceedes threshold value, such as:
Temperature becomes 30 DEG C from 20 DEG C, and SOC is still not less than 20%, then in use table 4, SOC is 20%
Corresponding form is charged, owing to the charging interval now is t1 ＜ t≤t2, then now use
The charging current of 320 peaces is battery charging, if over the increase of charging duration, but temperature and SOC
Never change, then the interval corresponding charging current using charging duration place is that battery enters
Row charging, if after charging duration is more than t5, then the charging current of 80 peaces is battery charging the most always.
If the numerical value after temperature and SOC change is when being above threshold value, such as: temperature becomes from 20 DEG C
30 DEG C, and SOC rises to 35% from 15%, then in use table 4, SOC is that the form of 40% correspondence enters
Row charging, due to a length of t1 ＜ t≤t2 during charging now, then now use the charged electricals of 240 peaces
Flowing and charge for battery, if over the increase of charging duration, but temperature and SOC never become
Change, then the interval corresponding charging current using charging duration place is that battery is charged, if filled
After electricity duration is more than t5, then the charging current of 60 peaces is battery charging the most always.
By that analogy, after changing according to a said method parameter in temperature and SOC, according to
Parameter after change and charging duration finally determine the charging current of correspondence.
