Description of the drawings

Fig. 1 is to be shown based on the pure electric automobile continual mileage evaluation method flow process of average energy consumption modeling in the embodiment of the present invention It is intended to;

Fig. 2 is the structure of the pure electric automobile continual mileage estimation device in the embodiment of the present invention based on average energy consumption modeling Schematic diagram.

Specific embodiment

For making the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with specific embodiment, and reference 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.

Step 103, according to air-conditioning use state and distance travelled number, the remaining continual mileage of estimation.

Used as embodiment, electric motor car is during traveling, and battery is mainly supplied to motor and two powerful devices of air-conditioning Electricity, the gross energy for consuming in time T after electricity in electric motor car:Wherein, U, I are respectively electricity 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.

Preferably, 5 kilometers of interval calculation average energy consumptions are defined, in order to iteration is realized, defines total energy consumption array:

PointEcost=[PointEcost1, PointEcost2, PointEcost3, PointEcost4, 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, Enumerator j cumulative 1, then the energy DetaEcost=Ecost-Ecosttemp for consuming in 1 kilometer of segment.Wherein Ecost is assigned to Ecosttemp, then according in the following manner assignment when DetaD is more than or equal to 1 by Ecosttemp again:

PointEcost1=PointEcost2, PointEcost2=PointEcost3, PointEcost3= PointEcost4, PointEcost4=PointEcost5, PointEcost5=PointEcost6;PointEcost6= Ecost;

Time1=time2, time2=time3, time3=time4, time4=time5, time5=time6, Time6=time.Wherein, Ecost, time are respectively current total energy consumption and running time.

Energy consumption Sum5Ecost=(5-j) * initEC+ when electric motor car operating range is less than 5 kilometers, in 5 kilometers of definition Ecosttemp, gross energy Sum5EcostAC=(5-j) the * initEC+EcosttempAC that air-conditioning is consumed.

J is 0 to 5 kilometers of integer, then average energy consumption AveEc=coff* (Sum5Ecost-Sum5EcostAC)/5.Its In, coff is that battery discharge coefficient, the value is related to battery behavior.Average energy consumption is determined before volume production, road on real vehicle During need to read the total energy expenditure in 5 kilometers of battery in real time, then to deduct the total energy expenditure of air-conditioning be exactly that garage makes When total energy expenditure, then be exactly the average energy consumption that recalculates divided by 5 kilometers.

Mean power Pmean=(5-j) * initPmean+j* (Ecost-EcostAC)/timetemp)/5, InitPmean is unit kilometer electric motor car power, and the initial value is provided by manufacturer.Now residue travels course continuation mileage Srest= (Etotal-Ecost)/AvgEc.

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 Consumption Sum5Ecost=(5-j) * initEC+Eco sttemp.Air conditioning energy consumption Sum5EcostAC=Eco stAC in 5 kilometers, Average energy consumption AveEc=coff* (Sum5Eco st-Sum5EcostAC)/5, mean power Pmean=((5-j) * 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 PointEcost1, air conditioning energy consumption in 5 kilometers:Sum5EcostAC=PointEcostAC6-PointEcostAC1, average energy Consumption:AveEc=coff* (Sum5Ecost-Sum5EcostAC)/5, the time used by 5 kilometers of traveling:Sum5time=time6- Time1, mean power:Pmean=Sum5Ecost/Sum5time, wheeled course continuation mileage:Srest=(Etotal- Ecosttemp-PAC*(Etotal-Ecosttemp)/Pmean)/AveEc.

After the completion of estimation, DetaD is emptied as 0, then makes Dtemp=D, circulates 1 course continuation mileage of estimation per 1 kilometer successively, 5 kilometers of alternative manners calculate average energy consumption.When the static i.e. gear of car is for N shelves or P shelves, when opening air-conditioning, flat before car is stopped Average energy consumption when all energy consumption AveEc is travelled as current remaining Che Suoneng, the power of air-conditioning is PACIf, electronic garage When sailing mileage less than 5 kilometers, mean power:Pmean=((6-j) * initPmean+j*Ecosttemp/timetemp)/5+ PAC, the course continuation mileage of wheeled:Srest=(Etotal-Ecost-PAC* (Etotal-Ecost)/Pmean)/AveEc, if empty When tune opens front electric motor car operating range more than 5 kilometers, 5 kilometers of running time Sum5time=time6-time1, average work( Rate Pmean=Sum5Ecost/Sum5time, the course continuation mileage S of wheeledrest=(Etotal-Ecost-PAC *(Etotal- Ecost)/Pmean)/AveEc.

Step 104, the remaining continual mileage to exporting is filtered processing.

In this embodiment, the remaining continual mileage to exporting is filtered processing, and can avoid the problem of fluctuating widely.

It is preferred that the present invention considers and there is driving cycle in vehicle travel process and drastically change, i.e. low-speed situations Lower course continuation mileage becomes big, and under high-speed case, course continuation mileage diminishes.Preferably, in order that driver is not changed by the amplitude, right The course continuation mileage of output carries out restriction adjustment, and current 1 kilometer of output mileage is Srestshow, and in 1 kilometer of output before Journey is compared for outshow.

If | outshow1-Srestshow |<1 kilometer, then outshow=Srestshow, the mileage that instrument shows is protected Hold 1 kilometer.

If Srestshow-outshow>1 kilometer, then count carry out add up i.e. count++.Work as count>When 3, then defeated Go out value outshow=outshow+CD1, the value of CD1 is 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 entered according to SOC Rower is fixed.

If 2<outshow1-Srestshow<When=10, outshow=outshow-CD3, CD3 enters rower according to SOC Fixed.

If outshow1-Srestshow>When 10, count1 carries out the count1++ that adds up.If count1>2, then Outshow=outshow-3, otherwise outshow=outshow-2.

Wherein, tri- parameters of described CD1, CD2, CD3 are the correction factor for pre-setting, and its demarcation is necessary to ensure that electricity Pond is Full Charge Capacity, then carries out working condition tests, the mileage number that when determining dead battery, garage makes, and electricity during garage is made Cell voltage, electric current, air-conditioning power, the information such as speed, gathered data is imported in SIMULINK model, by mould Type computing adjusts the value of three parameters, and the mileage variation tendency for calculating model is exercised mileage variation tendency with real vehicle and protected as far as possible Hold consistent.

Preferably, the span of correction factor CD1 is -3 to -1 for the span of 0.2 to 0.5, correction factor CD2, The span of correction factor CD3 is 0 to 1.

Also what deserves to be explained is, in one embodiment of the invention, step 104 can not be carried out.And the present invention's In another embodiment, in order to avoid the course continuation mileage for showing from fluctuating widely problem, hold after step 103 has been carried out Step 104 is gone.
