As shown in fig.1, for the pure electric automobile continual mileage based on average energy consumption modeling in first embodiment of the invention
Evaluation method flow diagram, the pure electric automobile continual mileage evaluation method based on average energy consumption modeling include：
Step 101, electric vehicle after the power is turned on, needs to detect present battery status.
In embodiment, electric vehicle after the power is turned on, the gross energy E that present battery can be providedtotal=SOC*SOH*C*U/
10000, wherein SOC are residual power percentage, and SOH is the health status of battery, and C is the specified electric quantity (unit of battery：Ah),
U is cell voltage (unit：V).
Step 102, the initial maximum continual mileage of wheeled is estimated according to present battery status and specified average energy consumption.
Wherein, vehicle can carry out working condition tests before volume production, for example vehicle can exercise how many mileage when battery full capacity,
I.e. the electricity divided by odometer of battery when energy consumption.In addition, speed is high sometimes for the operating mode exercised, speed is low sometimes, speed Gao Shineng
Consumption is big, and energy consumption is small when speed is low, therefore total electricity divided by total enforcement mileage are defined as specified average energy consumption by us.
As embodiment, initial continual mileage can be obtained by maximum residual continual mileage, i.e.,：Srest=Etotal/
initEC.Wherein, initEC is the energy (unit of unit kilometer electric vehicle consumption：Kwh/km), which can be according to statistic law pair
Specific operation (NEDC or at the uniform velocity) is counted and is demarcated, i.e. initEC=Emax/Lmax, EmaxFor vehicle rated energy (unit：
Kwh), LmaxFor in the max mileage number (unit of specific operation downward driving：km).Wherein, the max mileage number is according to each
A main engine plants carry out the numerical value that working condition tests provide, for example are exercised with average speed 60km/h when battery full capacity, and enforcement is arrived
Dead battery or vehicle can not exercise when 220km, then max mileage is 220km.If exercised with NEDC operating modes, can exercise
180km, therefore max mileage is defined as 220 or 180 needs main engine plants to define, major part main engine plants are in order to carry at present
Rise sale bright spot, it will usually which the mileage exercised at the uniform velocity 60km/h is the most maximum to exercise mileage.
Step 103, according to air-conditioning use state and mileage travelled number, remaining continual mileage is estimated.

Pond terminal voltage and bus current.With the consumption of energy, the course continuation mileage of electric vehicle wheeled is：Srest=(Etotal-
Ecost)/AvgEc.(high speed and low speed) every kilometer of flat consumable energy AvgEc is different in the case of considering difference, therefore,
The present invention estimates average energy consumption by the method for mileage iteration.Specifically implementation process includes：
Step 1：Initialization calculates the data of remaining continual mileage.
Preferably, carrying out the cumulative electric vehicle actual distance traveled that obtains of time to the speed of electric vehicle is set as D (units：
km).When traveling is whole kilometer, D can be assigned to temporary variable Dtemp, total energy consumption Ecost is assigned to temporary variable
Ecosttemp, running time time are assigned to temporary variable timetemp.Also, it is provided with counter j, initial value 0, traveling
Distance D often increases by 1 kilometer, counter j cumulative 1.Such as：Vehicle is exercising 1,2,3,4 ... can be by actual travel when waiting whole kilometer
Distance D values are assigned to intermediate variable Dtemp, then when travelling 4.3km, D=4.3, Dtemp=4.D and Dtemp can be carried out at this time
Additive operation, as vehicle is constantly exercised forward, D is ever-increasing, and when D=5 whole kilometers, Dtemp becomes 5.
As Ecosttemp with the principle of timetemp is, the value of total energy consumption Ecost when Ecosttemp represents whole kilometer,
The value that running time time is assigned to when timetemp represents whole kilometer.
Preferably, 5 kilometers of interval calculation average energy consumptions are defined, in order to realize iteration, define total energy consumption array：

Consumption AveEc can drive the average energy consumption that vehicle travels as current remaining, and the power of air-conditioning is PACIf in electric vehicle traveling
When journey is less than 5 kilometers, mean power：Pmean=((6-j) * initPmean+j*Ecosttemp/timetemp)/5+PAC, can
The course continuation mileage of traveling：Srest=(Etotal-Ecost-PAC* (Etotal-Ecost)/Pmean)/AveEc, if air-conditioning is beaten
When electric vehicle operating range is more than 5 kilometers before opening, 5 kilometers of running time Sum5time=time6-time1, mean power
Pmean=Sum5Ecost/Sum5time, the course continuation mileage S of wheeledrest=(Etotal-Ecost-PAC*(Etotal-
Ecost)/Pmean)/AveEc。
7. device according to claim 5, which is characterized in that right after the remaining continual mileage of construction unit estimation
The remaining continual mileage of output is filtered, including：
Current 1 kilometer of output mileage is Srestshow, and 1 kilometer of remaining mileage outshow is compared before；
If | outshow1-Srestshow |<1 kilometer, then outshow=Srestshow, the mileage that instrument is shown keep 1 public affairs
In；
If Srestshow-outshow>1 kilometer, then count adds up, and works as count>When 3, then output valve outshow=
The value of outshow+CD1, CD1 are demarcated according to SOC；Work as count<When 3, outshow=outshow-1；
If 1<outshow1-Srestshow<When=2, the value of outshow=outshow-CD2, CD2 is according to SOC into rower
It is fixed；
If 2<outshow1-Srestshow<When=10, outshow=outshow-CD3, CD3 is demarcated according to SOC；
If outshow1-Srestshow>When 10, count1 carries out cumulative count1++；If count1>2, then outshow
=outshow-3, otherwise outshow=outshow-2.
8. according to the device described in claim 5-7 any one, which is characterized in that when SOC residues 30%, Erest=SOC*
SOH*C*U/10000；Srest=ErestThe remaining mileage outshow of/AvgEc and average Estimation of energy consumption is compared, and is minimized
As final remaining continual mileage.
