Accompanying drawing, the present invention is described in more detail.
It should be noted that the statement of all use " first " and " second " is for distinguishing two in the embodiment of the present invention
The entity of individual same names non-equal or the parameter of non-equal, it is seen that " first " " second " should not only for the convenience that states
The restriction to the embodiment of the present invention is interpreted as, subsequent embodiment is no longer illustrated one by one to this.
Refering to shown in Fig. 1, be in first embodiment of the invention based on average energy consumption modeling pure electric automobile continual mileage
Evaluation method schematic flow sheet, the pure electric automobile continual mileage evaluation method based on average energy consumption modeling includes：
Step 101, in electric motor car after electricity, needs to detect present battery status.
In an embodiment, in electric motor car after electricity, the gross energy E that present battery can be provided bytotal=SOC*SOH*C*U/
10000, wherein SOC are dump energy percentage ratio, 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, estimates the initial maximum continual mileage of wheeled according to present battery status and specified average energy consumption.
Wherein, when vehicle can carry out working condition tests, such as battery full capacity before volume production, car can exercise how many mileages,
That is the electricity of battery is divided by energy consumption during speedometer.Further, speed is high sometimes for the operating mode of enforcement, and speed is low sometimes, speed Gao Shineng
Consumption is big, and when speed is low, energy consumption is little, and therefore total electricity is defined as specified average energy consumption divided by total enforcement mileage by us.
Used 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 motor car consumption：Kwh/km), the value 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), LmaxIt is the max mileage number (unit in specific operation downward driving：km).Wherein, described max mileage number is that basis is each
Individual main engine plants carry out exercising with average speed 60km/h during the numerical value that working condition tests are given, such as battery full capacity, and enforcement is arrived
During 220km, dead battery or car cannot be exercised, then max mileage is 220km.If exercised with NEDC operating mode, then can exercise
180km, therefore max mileage be defined as 220 or 180 and need main engine plants to define, major part main engine plants are in order to carry at present
Rise sale bright spot, it will usually with the mileage the most maximum enforcement mileage that at the uniform velocity 60km/h is exercised.

Pond terminal voltage and bus current.With the consumption of energy, the course continuation mileage of electric motor car wheeled is：Srest=(Etotal-
Ecost)/AvgEc.In the case of consideration difference, (at a high speed with low speed) per kilometer of flat consumable energy AvgEc is different, therefore,
The present invention estimates average energy consumption by the method for mileage iteration.Specific implementation process includes：
Step one：Initialization calculates the data of remaining continual mileage.
It is preferred that carrying out the cumulative electric motor car actual travel distance that obtains of time to the speed of electric motor car to be set to D (unit：
km).When travelling as whole kilometer, D can be assigned to temporary variable Dtemp, total energy consumption Ecost is assigned to temporary variable
Ecosttemp, running time time is assigned to temporary variable timetemp.Also, enumerator j is provided with, initial value is 0, to travel
Often increase by 1 kilometer apart from D, enumerator j cumulative 1.For example：Car is exercising 1,2,3,4 ... can be by actual travel when waiting whole kilometer
Intermediate variable Dtemp is assigned to apart from D value, then when 4.3km is travelled, D=4.3, Dtemp=4.Now D and Dtemp can be carried out
Additive operation, as car is constantly exercised forward, D is ever-increasing, and when D=5 whole kilometer, Dtemp is changed into 5.
As Ecosttemp with the principle of timetemp is, the value of total energy consumption Ecost when Ecosttemp represents whole kilometer,
The value that when timetemp represents whole kilometer, running time time is assigned to.

PointEcost5, PointEcost6], air conditioner energy consumes array：
PointEcostAC=[PointEcostAC1, PointEcostAC2, PointEcostAC3,
PointEcostAC4, PointEcostAC5, PointEcostAC6],
Time array：Time=[time1, time2, time3, time4, time5, time6], and each array element
Initial value is 0.
Step 2, loop iteration calculates average energy consumption.
Specifically, it is real-time change to obtain range information D=∫ vdt, wherein D by actual speed to the accumulation of time
's.Dtemp changes 1 time per 1 kilometer, setpoint distance interval D etaD=D-Dtemp, when being more than or equal to 1 apart from interval D etaD,

Segment in consume energy：
DetaEcost=Ecost-Ecosttemp,
Now
PointEcost1=PointEcost2；PointEcost2=PointEcost3；PointEcost3=
PointEcost4；PointEcost4=PointEcost5；PointEcost5=PointEcost6；PointEcost6=
Ecost,
Time1=time2；Time2=time3；Time3=time4；Time4=time5；Time5=time6；
Time6=time,
PointEcostAC1=PointEcostAC2；PointEcostAC2=PointEcostAC3；
PointEcostAC3=PointEcostAC4；PointEcostAC5=PointEcostAC6；PointEcostAC6=
EcostAC, wherein, the total energy consumption that EcostAC is consumed for air-conditioning.
The calculating of average energy consumption is divided into 2 parts, the total energy when electric motor car operating range is less than 5 kilometers, in 5 kilometers of definition

initPmean+j*Ecosttemp/timetemp)/5+PAC；The course continuation mileage of wheeled：Srest=(Etotal-
Ecosttemp-PAC*(Etotal-Ecosttemp)/Pmean)/AveEc.
When electric motor car operating range is more than 5 kilometers, the total energy consumption Sum5Ecost=PointEcost6- in 5 kilometers
