Fig. 2A is a kind of flow chart of the update method of battery parameter according to an exemplary embodiment, such as Fig. 2A institutes
Show, this method comprises the following steps：
Step 201：Determine the current discharge and recharge number of battery.
In embodiments of the present invention, battery can be lithium battery, can also other kinds of battery, as long as the capacity of battery
Reduced with the increase of discharge and recharge number.
Because battery is after one circulation of discharge and recharge, battery capacity can reduce in real time, if now also according to battery
Active volume of dispatching from the factory when dispatching from the factory carries out the display of battery electric quantity, and according to the maximum charging current corresponding to active volume that dispatches from the factory
Charged, then, it will cause the battery electric quantity of display inaccurate, and certain potential safety hazard is caused during charging.However,
Caused by exactly because these problems are with the increase of the discharge and recharge number of battery, therefore, in order to overcome these problems, it is necessary to
The current discharge and recharge number of battery is first determined, is that the actual battery capacity that battery is calculated in subsequent step does basis.
Wherein, the current discharge and recharge number of battery is determined according to the discharge voltage and charging voltage of battery, that is, works as battery
Current discharge voltage is less than first voltage thresholding, and when current charging voltage is more than second voltage thresholding, to last true
The discharge and recharge number of fixed battery is increased, and obtains the current discharge and recharge number of battery.Such as the last battery determined
Discharge and recharge number is 10 times, if the current discharge voltage of battery is less than first voltage thresholding, afterwards, the charging for detecting battery is electric
Pressure, when the charging voltage of battery is more than second voltage thresholding, show that battery carries out the circulation of a discharge and recharge, at this point it is possible to
The discharge and recharge number 10 times that last time is determined plus 1, the current discharge and recharge number of battery is obtained as 11.
Step 202：Active volume of dispatching from the factory based on the current discharge and recharge number of battery and battery, is estimated according to preset capacity
Model, the current actually available capacity of estimation battery.
Wherein, preset capacity appraising model is after carrying out multiple charge and discharge cycles test to test battery, to pass through test
Data determine to obtain, size, capacity and the species all same of test battery and the battery.
It should be noted that preset capacity appraising model is developer according to calculating simply and calculate accurate two standards
It is determined that obtain, for the estimation of battery capacity.In order to determine preset capacity appraising model, test battery can be tested,
And then determine preset capacity appraising model.And in order to improve the precision for determining test battery capacity, polylith can be selected to survey
Examination battery is tested, and the size, capacity and species all same of the test battery and the battery in the present invention.
Wherein, preset capacity appraising model can be：Or
Wherein, y is the actually available capacity of battery, and C is the active volume of dispatching from the factory of battery, and a, b, c are constant.
Next determine that the process of preset capacity appraising model is simply introduced to developer
As shown in Figure 2 B, two pieces of test batteries have been selected to be tested, curve 1 is to test first piece of test battery
Obtained test data, curve 2 are the test data for being tested to obtain to second piece of test battery, i.e. charge-discharge test
Number is 1000 times, two cell set capacity data corresponding to two pieces of test batteries is obtained by 1000 tests, per cell set capacity
Data are 1000, further according to charge-discharge test number and every cell set capacity data, filling shown in making curve 1 and curve 2
Change curve between discharge test number and battery capacity.
It can be seen from the graph that battery capacity and the corresponding relation of charge-discharge test number are not linear change
, that is, the monotonic nature of monotonic function is not met, but there is certain radian, generally meet the characteristic of inverse proportion function,
I.e. as the increase of charge and discharge testing time, battery capacity are gradually reduced.Therefore can be by charge and discharge testing time and pair of battery capacity
It should be related to and be arranged to following first formula：
Wherein, a, b, c are three constants, and C is that battery dispatches from the factory active volume, and x be discharge and recharge number, y for battery reality
Active volume.
, can be in the charge-discharge test number and battery capacity shown in Fig. 2 B in order to determine three constants in the first formula
Three effective nodes are chosen in change curve, and three effective nodes are substituted into the first formula, so that it is determined that a, b, c tri- is often
Number.Wherein, effective node refers to the high point of two curve co-insides degree, and the registration of two curves is higher, i.e., two curves are heavier
Close, the point of selection is more effective.
When it is determined that after tri- constants of a, b, c in the first formula, now, just only two unknown number x in the first formula
And y, therefore 0-1000 discharge and recharge number can be substituted into the first formula, so as to obtain the actually available capacity of battery.Finally,
, can when the error between the battery capacity that the actually available capacity for the battery being calculated and test obtain is less than default error
To determine to obtain preset capacity appraising model, as shown in Figure 2 C, curve 3 is that the preset capacity for determining to obtain by the above method is estimated
Calculate the curve that model is drawn.Mistake between the battery capacity that the actually available capacity for the battery being calculated and test obtain
, it is necessary to three effective nodes be reselected, so as to recalculate a, b, c in the first formula when difference is more than or equal to default error
Three constants.
For example, 1000 battery capacities in 1000 battery capacities on curve 3 and curve 1 are subtracted each other to obtain 1000
Error amount, judge whether there are 990 error amounts to be less than 0.1 in this 1000 error amounts；Similarly, then by 1000 on curve 3
Battery capacity is subtracted each other with 1000 battery capacities on curve 2 obtains 1000 error amounts again, judges in this 1000 error amounts
Whether there are 990 error amounts to be less than 0.1.If in this two groups of 1000 error amounts, being satisfied by each group has 990 error amounts to be less than
0.1, then it can determine to obtain preset capacity appraising model.Wherein, 990 be predetermined number, and 0.1 is default error.
When the preset capacity appraising model for determining to obtain by the above method estimates the actually available capacity of battery, estimation
Results contrast is accurate.However, in order to simplify the complexity of calculating, it can be assumed that right when battery charging and discharging number x is positive infinity
The y answered is 0mAh, now c=0, and so, above-mentioned first formula can be deformed into following second formula：
It should be noted that when discharge and recharge number x is positive infinity, i.e., battery can be used ad infinitum in discharge and recharge, this
When battery capacity can be depleted, that is to say, as x=+ ∞, y=0, substitute into formula, obtain c=0.Certain such case is in reality
It is not present in realization, but can be used in theory deduction, the embodiment of the present invention is with the reality of closest estimation battery
The evaluation method of active volume is estimated.
Then, choosing two in the change curve between the charge-discharge test number shown in Fig. 2 B and battery capacity has
Node is imitated, and two effective nodes are substituted into the second formula, determines two constants of a, b.Wherein, effective node refers to two curves
The high point of registration, the registration of two curves is higher, i.e., two curves more overlap, and the point of selection is more effective.
When it is determined that after two constants of a, b in the second formula, now, in the second formula just only two unknown number x and
Y, therefore 0-1000 discharge and recharge number can be substituted into the second formula, so as to obtain the actually available capacity of battery.Finally, when
, can be with when error between the battery capacity that the actually available capacity of the battery being calculated and test obtain is less than default error
It is determined that obtain preset capacity appraising model.
It that is to say, may finally determine to obtain two kinds of preset capacity appraising models by the above method, and the first is default
The estimation result of volume calculation model is more accurate, and the estimation process of second of preset capacity appraising model is fairly simple, therefore,
Actual demand can be directed to, a kind of model is selected from two kinds of preset capacity appraising models, so as to be integrated into implementation of the present invention
In the battery parameter updating device of example.
Step 203：The capacity of battery is updated to currently to estimate obtained actually available capacity, and current based on battery
Actually available capacity, the charge parameter of battery is updated.
In practical application, directly battery capacity and charge parameter can be carried out more after each discharge and recharge of battery
Newly, it is of course also possible to be updated when battery capacity changes greatly to battery capacity and charge parameter, therefore, next
Both possible implementations will be illustrated respectively.
The first possible implementation：When estimation obtains the actually available capacity of battery, immediately by the capacity of battery
It is updated to currently estimate obtained actually available capacity, and based on the current actually available capacity of battery, the charging ginseng to battery
Number is updated, i.e., battery capacity and charge parameter is updated after each discharge and recharge of battery.
In the mode of real-time update battery capacity, as long as the discharge and recharge number increase of battery, the reality of battery is just estimated
Active volume, then battery capacity is updated to currently to estimate obtained actually available capacity, and based on the current reality of battery
Active volume, the charge parameter of battery is updated.So, renewal that can in time to battery capacity and charge parameter.
Second of possible implementation：When estimation obtains the actually available capacity of battery, last time renewal can be obtained
The actually available capacity of battery when the capacity and charge parameter of battery, the actually available capacity of the battery of acquisition is subtracted into battery and worked as
Preceding actually available capacity, obtains capacity difference.When the capacity difference is more than preset capacity, the capacity of battery is updated to work as
It is preceding to estimate obtained actually available capacity, and based on the current actually available capacity of battery, the charge parameter of battery is carried out more
Newly.Battery capacity and charge parameter are updated when the volume change of battery is larger.
Wherein, preset capacity is to pre-set for a variable quantity comparing.
In addition, the actually available capacity of battery has two kinds of acquisition sides when obtaining the capacity and charge parameter of last time renewal battery
Method.The first acquisition methods：The discharge and recharge number of battery when first obtaining last time renewal battery capacity and charge parameter, further according to this
Charging times calculate corresponding battery capacity according to preset capacity appraising model.Second of acquisition methods：Directly obtain last time more
The actually available capacity of battery, that is to say when new battery capacity and charge parameter, when updating last time, can store last time renewal electricity
The actually available capacity of battery when tankage and charge parameter.
Wherein, when the charge parameter of battery includes maximum charging current, based on the current actually available capacity pair of battery
The operation that charge parameter is updated can be：The current actually available capacity of battery is multiplied with preset multiple, obtains battery
Current actual maximum charging current, and the maximum charging current of battery is updated to actual maximum charging current.Wherein, this is pre-
If multiple is the multiple pre-set.For example, the actually available capacity when battery currently is 30mah, preset multiple 0.5, this
Sample, the current actual maximum charging current 30mah*0.5=15ma of battery can be obtained.
Further, when the current discharge and recharge number of battery reaches preset times, battery altering prompt message is shown.
It is, due to consideration that the usage time limitation of actual service condition and battery, the discharge and recharge number of battery are typically limited
Value, can be arranged to preset times by the finite value, when the current discharge and recharge number of battery reaches preset times, show battery
Actually available capacity very little, at this point it is possible to show battery altering prompt message, prompt user to change battery.
In embodiments of the present invention, can root in order to which battery electric quantity is explicitly more accurate, and during battery charges
Factually the maximum charging current on border is charged, it is necessary to estimate the actually available capacity of battery.In practical implementations, it is necessary to first
The current discharge and recharge number of battery, then the active volume of dispatching from the factory based on discharge and recharge number and battery are determined, is estimated according to preset capacity
Model is calculated, estimates the current actually available capacity of battery, wherein, preset capacity appraising model is that test battery is repeatedly filled
After discharge cycles test, determine to obtain by test data, and size, capacity and the species of testing battery and battery are homogeneous
Together；Finally the capacity of battery is updated to currently to estimate obtained actually available capacity, and based on current actually available of battery
Capacity, the charge parameter of battery is updated, in this way, realizing the estimation to the actually available capacity of battery.So, can be with
Battery electric quantity is shown according to the actually available capacity of battery exactly, additionally it is possible to the maximum charging current of battery is updated,
Ensure the security of charging.
