Power consumption values under the current working are that VCU extracts vehicle mileage, while receiving battery controller BMS sending Message, to extract total discharge energy in set distance, the every traveling set distance of vehicle, VCU is calculated under a current working Average kilometer power consumption values are calculated by the following formula:
W is current=EIf/SIf, wherein EIfFor discharge energy total in set distance, unit Wh/m；SIfFor set distance, unit m。
S sky is determined by current remaining value, is calculated as follows:
S sky=kx, wherein k is constant, and x is the percentage that current remaining accounts for battery gross energy, %.
The beneficial effects of the present invention are:
The technical program obtains current dump energy according to standard condition according to the NEDC operating condition average energy consumption of standard The mileage that can be travelled down, however operating condition difference average energy consumption difference is larger, so to use current vehicle average in real time The be averaged deviation of kilometer energy consumption of kilometer energy consumption and standard compensates, and obtains accurate remaining mileage.
Detailed description of the invention
Fig. 1 is remaining mileage vehicle estimation mode figure；
Fig. 2 is that difference SOE corresponds to remaining mileage reduction value comparison table when air-conditioning is opened.
Specific embodiment
Carry out the technical solution that the present invention will be described in detail by the following examples, embodiment below is merely exemplary, only It can be used to explanation and illustration technical solution of the present invention, and be not to be construed as the limitation to technical solution of the present invention.
The application provides a kind of evaluation method of Remainder Range of Electric Vehicle, as shown in Figure 1, comprising:
VCU acquire present battery residual energy magnitude, the power consumption values under current working and air-conditioning whether opening imformation.
Entire car controller VCU receives the message that battery management system BMS is issued by bus, therefrom proposes that power battery is total , bus current I mother female at busbar voltage U, carries out watt-hour integral by VCU, watt-hour integration period is usually that 10ms:VCU joins again It is admitted to time charge and discharge latter stage dump energy and dump energy is calculated according to rechargeable energy and discharge energy in real time.
The E is surplus to be calculated by the following formula calculating:
E remains=∫t 0UIt is female×IIt is femaleDt, SOE=(E0+EIt fills- EIt puts+ERecycling)*SOH/E0, wherein E0For specified primary power, EIt fillsFor The energy being filled with, EIt putsFor the energy of releasing, ERecyclingFor the energy of braking recycling, SOH is the health degree of battery.
Power consumption values under the current working, are the messages that VCU receives that instrument issues, and resolution ratio is used in the application 0.1km extracts vehicle mileage, while receiving the message that battery controller BMS is issued by bus, to extract set distance Total discharge energy in (this uses 0.1km), the every traveling 0.1km of vehicle, VCU calculates the average kilometer under a current working Power consumption values are calculated by the following formula:
W is current=EIf/SIf, wherein EIfFor discharge energy total in set distance, unit Wh/m；SIfFor set distance, unit m.In the present embodiment, W it is current=E0.1km/0.1。
The W standard is to demarcate by revolving drum test table frame, the every traveling 1km mean consumption of vehicle under the NEDC operating condition of city Energy, energy on this is positioned as standard and is averaged kilometer energy (W standard).
If when power consumption values≤W standard under current working, and air-conditioning is not turned on, then remaining mileage is counted as follows It calculates:
S residue=E residue/W standard+∑ (1-W current/W standard) × 0.1；
If air-conditioning is opened, remaining mileage calculates as follows:
S residue=E residue/W standard+∑ (1-W current/W standard) × 0.1-S is empty；
If when power consumption values > W standard under current working, and air-conditioning is not turned on, then remaining mileage is counted as follows It calculates:
S is surplus=and E is surplus/W standard+∑ (W current/W standard -1) × 0.1；
If air-conditioning is opened, remaining mileage calculates as follows:
S is surplus=and E is surplus/and W standard+∑ (W current/W standard -1) × 0.1-S is empty；
Wherein, the remaining mileage that S remains as estimation, unit km；E remains as current remaining, unit Wh；
W standard is the energy consumption under NEDC standard condition, unit Wh/m；W is currently the energy consumption under current working, and unit is Wh/m；S sky is the mileage of air-conditioning consumption；0.1 is 0.1m.
The technical program according to the NEDC operating condition average energy consumption of standard, obtains current dump energy according to standard condition first The mileage that can be travelled down, i.e. E remain/W standard.
Then, because average energy consumption has bigger difference under the energy consumption of actual condition and standard NEDC operating condition, with currently The deviation of average energy consumption compensates under vehicle real time energy consumption (the application is using the energy consumption in 0.1km) and standard NEDC operating condition.
Air-conditioning is opened, and remaining mileage can be to low jump, therefore, and when vehicle driving calculates average energy consumption, should subtract air-conditioning Etc. secondary energy consumption, and in the case where air-conditioning is not turned on, when vehicle driving, calculates average energy consumption, and there is no need to subtract air-conditioning etc. Secondary energy consumption.
As shown in Fig. 2, VMT Vehicle-Miles of Travel reduces 30km, and air-conditioning is opened when air-conditioning unlatching refrigeration can be obtained by test data Qi Shi carries out linear change substantially according to Fig. 2 list.
When air-conditioning is opened and freezes, power is opened by taking 1.5-2KW as an example, S sky is determined by current remaining value, is pressed Following formula calculates:
S sky=kx, wherein k is constant, and x is the percentage that current remaining accounts for battery gross energy, unit %.At this In embodiment, K 30.
It opens when closing air-conditioning again after air-conditioning, it is corresponding that air-conditioning of the remaining mileage value added between is not turned on state, I.e. if SOE 50%, remaining mileage 75km close air-conditioning at this time, and remaining mileage becomes 75km+15km when opening air-conditioning =90km.
Air-conditioning opens heating power, on time with air conditioner refrigerating when identical parameter value calculated.
If air-conditioning is opened, but vehicle does not travel, at this time the energy consumption of air-conditioning to remaining mileage.
Although present invention combination above embodiments are described, the present invention is not limited to above-described embodiment, And be only defined by the appended claims, those of ordinary skill in the art easily can modify and change to it, but simultaneously Without departing from essential idea and range of the invention.
