To the present battery capacity of power battery.
Such as: the volume change amount of power battery is calculated by current integration method first, and is checked in by load method
Then the residual capacity variable quantity of power battery changes the volume change amount of power battery and the residual capacity of power battery
Present battery capacity of the ratio of amount as power battery.
In order to improve power battery present battery capacity calculating accuracy, can repeatedly calculate battery capacity, and will
Present battery capacity of the average value of the battery capacity repeatedly calculated as power battery, in this way, power battery can be improved
The calculating accuracy of present battery capacity.
Specifically, choosing multiple volume change sections and residual capacity constant interval, calculates and correspond to the change of multiple capacity
Change multiple volume change amounts in section and multiple residual capacity variable quantities corresponding to residual capacity constant interval, according to multiple

Value, and using average value as the present battery capacity of power battery.
For 5, as shown in Fig. 2, choosing 5 sections in entire charging process to calculate △ SOCiWith △ Ci,
In, △ CiFor the volume change amount of power battery, △ SOCiFor the residual capacity variable quantity of power battery.As shown in connection with fig. 2, then
Have: △ SOCi=SOCi+5-SOCi, △ Ci=Ci+5-Ci。
Since the variation range of the residual capacity SOC of power battery is 100% to SOCinit, wherein SOCinitFor electric power electricity
The initial residual capacity in pond.
Then: working as 100%-SOCinitWhen >=preset threshold (that is: preset threshold such as 50%), SOC1=SOCinit, C1=0Ah,
Wherein, SOCinitFor the initial remaining capacity of power battery.
According to △ CiWith △ SOCiCalculate the capacity of power battery, the i.e. capacity C of power batteryi=△ Ci/△SOCi,

Less than or equal to predetermined value, then the numerical value of preset dynamic weight coefficient is adjusted as the numerical value greater than 0, and if variance is greater than in advance
Definite value, then the numerical value for adjusting preset dynamic weight coefficient is 0.
As a specific example, as (100%-SOCinitWhen) >=50%, present battery is held using variance algorithm
The credibility of amount is judged, specifically, can determine the credible of present battery capacity according to the variance of present battery capacity
Property.Such as:
Battery capacity CiVariance б are as follows:
Wherein
The ideal value of б is 0.
Then, as б≤predetermined value (predetermined value such as 5Ah), then it is assumed that the battery capacity C estimated at this timeiBe it is believable, can
To calculate the first health status SOH, in one embodiment of the invention, at this point it is possible to take the numerical value k=of dynamic weight coefficient
0.5；
As б > 5Ah, then it is assumed that the battery capacity C estimated at this timeiBe it is incredible, therefore, take dynamic weight coefficient
Numerical value k=0.
By above-mentioned analysis, according to the first health status and preset dynamic weight coefficient adjusted to power battery
Second health status is modified, and can be modified by following formula to the second health status, the formula are as follows:
The correction value of second health status=(1-k) * SOHcyc+k*SOHλ, wherein SOHcycFor the second health status, SOHλ
For the first health status.
After being modified to the second health status, the method for the embodiment of the present invention further include:
S105: the third health status of the power battery stored when electricity according to the correction value of the second health status and under last time
Determine the final health status of power battery.
Take the correction value of the second health status and it is electric under last time when the third health status of power battery that stores in compared with
Small value is as final health status.
Such as: final health status=min [(1-k) * SOHcyc+k*SOHλ, SOHstore], wherein SOHstoreFor under last time
The value of the third health status of the power battery stored when electric.
It is as (100%-SOC aboveinitWhen) >=50%, the final health status determined, in other examples of the invention
In, further includes: when the difference between the full residual capacity of power battery and the initial residual capacity of power battery is less than default threshold
When value, the numerical value for adjusting preset dynamic weight coefficient is 0, it may be assumed that as (100%-SOCinitWhen) < 50%, then final healthy shape
State=min [SOHcyc, SOHstore]。
