Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings power battery management method, system and the automobile of the embodiment of the present invention described.
The embodiment of the present invention one provides a kind of power battery management method.Fig. 1 is the power that the embodiment of the present invention one is provided
The flow chart of battery management method.As shown in figure 1, the method in the present embodiment, can include：
Step 101, when battery charges, obtain current charge type.
Method in the present embodiment, can apply to new-energy automobile, and power source is used as in particular by electrokinetic cell
New-energy automobile.When being charged to battery, charge type is obtained, charge type can be to fill soon or trickle charge.Acquisition is filled
The specific method of electric type belongs to prior art, and here is omitted.
If step 102, current charge type fill number of times and plus one soon to fill soon, and judge described to fill whether number of times reaches soon
To frequency threshold value.
If step 103, reaching frequency threshold value, user is pointed out to switch to trickle charge.
Obtain after current charge type, it can be determined that charge type is to fill soon or trickle charge, if filling soon, then fills number of times soon
Plus one, and when filling number of times soon and reaching frequency threshold value, point out user to switch to trickle charge.
When automobile dispatches from the factory, number of times is filled soon and can be set as 0.During user's use, filling soon every time can will be fast
Fill number of times and plus 1, number of times is filled soon can be stored in EEPROM (Electrically Erasable Programmable Read-
Only Memory, EEPROM) or other memories in.With filling being continuously increased for number of times, battery soon
Loss be also continuously increased, when it is total fill number of times soon and reach corresponding frequency threshold value when, user can be pointed out, so that real
Now to the protection of battery.
The frequency threshold value can be set according to actual needs.For example, can be determined according to the electrochemical properties of battery
The discharge and recharge rule of battery, and according to discharge and recharge rule determined number threshold value；Or, charge-discharge test is carried out to a large amount of batteries,
According to charge-discharge test data determined number threshold value, for example, being found after analyzing experimental data, some type of battery is fast
Fill after 1000 times, battery performance is had compared with lossy, it is difficult to recover, then the frequency threshold value can be 1000 or be slightly smaller than
1000 number of times such as 900 etc..
Preferably, if current charge type is trickle charge, number of times clearing will can soon be filled.In this case, fill soon
Number of times refers to continuously fill number of times soon, if continuous when filling number of times soon and reaching corresponding frequency threshold value, user can be pointed out to switch to slowly
Fill.
Further, the corresponding threshold value of number of times continuously being filled soon can have multiple, be issued the user with when reaching different threshold values
Prompting it is also different.For example, the frequency threshold value can include the first frequency threshold value and the second frequency threshold value, first number
Threshold value is less than second frequency threshold value.
Accordingly, in step 102 judge it is described fill whether number of times reaches frequency threshold value soon, can be specially：Judge institute
State and fill whether number of times reaches the second frequency threshold value soon, if not up to the second frequency threshold value, judge described to fill whether number of times reaches soon
To the first frequency threshold value.
If reaching frequency threshold value in step 103, point out user to switch to trickle charge, can include：If described fill secondary soon
Number reaches the first frequency threshold value but not up to the second frequency threshold value, then points out user to switch to trickle charge；If the number of times that fills soon reaches
To the second frequency threshold value, then point out user to switch to trickle charge, be simultaneously emitted by caution signal.Continue fast when reaching the second frequency threshold value
The harm for continuing to fill soon when the hazard ratio filled only reaches the first frequency threshold value is bigger.
Specifically, when filling number of times soon between the first frequency threshold value and the second frequency threshold value, it can push and carry to user
Awake information, prompting message can be pushed to user in the way of voice or word, it is proposed that user switches to trickle charge, while may be used also
With the harm for reminding user to fill soon for a long time, if switching to trickle charge or terminating charging can voluntarily be selected by user.
When filling number of times soon and reaching the second frequency threshold value, warning message can be pushed to user, warning message can also be with
The mode of voice or word is pushed to user, and warning user is currently needed for switching to trickle charge, and the head of a household is used while can also remind
The harm that phase fills soon, if switching to trickle charge or terminating charging can voluntarily be selected by user.
Further, when reaching the second frequency threshold value, it can be sent out caution signal, described send warning signal can be with
Including following at least one：Vibrator vibration, buzzer warning, indicator lamp flicker, voice message, prominent text importing etc., side
Just it is currently prompting or warning that user, which distinguishes,.
Or, when filling number of times soon and reaching the first frequency threshold value but not up to the second frequency threshold value, it can also give a warning
Signal, to realize the prompting to user.In this case, as long as the caution signal sent when reaching the first frequency threshold value is with reaching
The caution signal sent during the second frequency threshold value is different.
For example, the caution signal is buzzer warning, fill soon number of times the first frequency threshold value and the second frequency threshold value it
Between when, time of buzzer warning is shorter, sound frequency is relatively low, when filling number of times soon and reaching the second frequency threshold value, buzzer warning
Time is longer, sound frequency is higher；Or, the caution signal is voice message, fill soon number of times in the first frequency threshold value and
When between the second frequency threshold value, " prompting " printed words are contained in voice message, when filling number of times soon and reaching the second frequency threshold value, voice is carried
Contain " warning " printed words in showing；Or, the caution signal is prominent text importing, and number of times is filled soon in the first frequency threshold value and the
When between two frequency threshold values, pointing out the word of user's switching trickle charge can be shown as comparing subdued colour such as orange, fill secondary soon
When number reaches the second frequency threshold value, word can be shown as than more prominent color such as red.
First frequency threshold value and second frequency threshold value can be set according to actual needs.For example, according to reality
Room data analysis discovery is tested, is continuously filled soon more than 10 times, the performance of battery, which has, to be decreased obviously, then first frequency threshold value can
Think 10；Continuously fill soon more than 20 times, the performance of battery, which has, significantly to be declined, then second frequency threshold value can be 20.
In actual applications, when being filled soon to battery every time, all number of times will be filled soon and plus 1, reached time when filling number of times soon
During number threshold value, it can be sent to user by modes such as voice or words and remind or alert, point out user to switch to trickle charge, used
Family can voluntarily be selected to continue to fill soon or switch to trickle charge or terminate charging, and user can be helped to form good custom,
Proper use of new-energy automobile, certain effect is slowed down so as to be played to the degradation of electrokinetic cell.
The power battery management method that the present embodiment is provided, by obtaining current charge type when battery charges, if working as
Preceding charge type then fills number of times and plus one to fill soon soon, and judge it is described fill whether number of times reaches frequency threshold value soon, reaching number of times
During threshold value, then point out user to switch to trickle charge, can timely and effectively help user to form good charging custom, it is to avoid warp
The problem of quick exhaustion of battery, battery consistency variation and continual mileage quickly shorten caused by often filling soon, improves battery
Service life.
