Transcript of "NREL Drive cycle data focused tools- matching the right tech to the right app"

  1. 1. NREL is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, operated by the Alliance for Sustainable Energy, LLC.Drive Cycle Data-Focused Tools:Matching the Right Technologyto the Right ApplicationNational Renewable Energy LaboratoryNAFA Smart Alt Fuel and Tech Choice WorkshopApril 25, 2013Kevin Walkowicz
  2. 2. Background:Lots of Work by the DOE and National Labs to Collect, Analyze and Report onNewly Deployed Advanced TechnologyBuy it, then try it: Evaluations ofnewly deployed technology arevery useful, but are a backwardlooking approachTry it before you buy it. Simulate it:Evaluate by looking forward….simulation andmodeling has been done before , but good datais needed for accurate assessment.
  3. 3. Refined Data to Make Informed Decisions• Drive-Cycle/Duty-CycleData• Speed– Acceleration– Miles– hours driven• Grade & payload• Power take off,auxiliary loads• Operating-Condition Data• Temperature, humidity• Payload• Vocational Analysis /Database• Route, fleet averages• Situational Modeling andSimulation• Sensitivity studies• Placement optimization• Expected performanceData in… Information out…• Online Resources• Clean Cities• Alternative Fuels DataCenter
  4. 4. National Renewable Energy Laboratory Innovation for Our Energy FutureDrive Cycle will Influence:1. Fuel economy2. Component life3. Life cycle costs/payback4. Optimal placement ofvehicles for maximumROIUnderstand the Duty Cycle = Understand the Technology: aerodevices, low rolling resistance tires, engine sizing, transmissionoptions, light-weighting, battery usage, driver feedback, etc.
  5. 5. 1. Collect In-Use Data:•Acquire Field Data•Process Data:•DRIVETM•FAT (Fleet Analysis Tool)•Compile & Summarize:•Fleet DNA3. Validate in Laboratory:•Validate field data in acontrolled setting•Quantify emissions and fuelconsumption•Explore limits, assess changesto system2. Analyze and Simulate:•Utilize User Specific Field Data•Vehicle Simulation:•FASTSim•Autonomie•Benefit Analysis:•best technology forspecific applicationAn Approach to Assess New TechnologyEasily process data: DRIVECompile and Compare to Industry: Fleet DNAPerform Simulations on Daily Operational Data: FASTSim
  6. 6. Understanding Vocational Behavior: Fleet DNAOnline vocational database of vehicle-use information• Phase 1: Pre-Sorted data sets: • Phase 2: Sortable Data Sets:User can custom sort and graph:• Class• Vocation• Fuel Type (or drivetrain)• Region (4)• Sub-region (based on census map)
  7. 7. Fleet DNA Benefits• OEMs– Better understanding ofcustomer-use profiles• Fleets– Determine maximum ROIfrom investment• Funding agencies– Optimize impact offinancial incentive offers• Researchers– Data source for modelingand simulationFleet DNA features:• Aggregated and anonymousdata– Fleets are not identified• 20-plus high-value metrics• Data products for eachvocation• Data for industry drive-cycledevelopment
  8. 8. Example Data Output of Fleet DNA:Phase I• Data products that visualize and calculate vehicle usepatterns• Visualizations that show data variability• Data analysis enables calculated decision making

  10. 10. Drive-cycle Rapid Investigation, Visualization and Evaluation Tool (DRIVETM)• Created to help fleets andOEMs analyze vehicleusage data for propervehicle placement, designand testing• Combines large amountsof user data then filters,creates new cycles &identifies best fittingexisting cycle• Integrated with Fleet DNAfor public use• Quickly processes andanalyzes data :• over 150 metrics• histograms• scatter plots• Creates custom cycle• Recommendsstandard cyclesData Analysis: Drive Cycle Data
  11. 11. Future Automotive Systems Technology Simulator (FASTSim)• Vehicle modeling tool tocomplimentary toAutonomie• FastSim is well suited forconducting large datasweeps– short run time inaccessible Excelenvironment– Validated performanceoutput: fuel economy andcost resultsData Analysis: Simulation
  12. 12. 1. Acquire data from sampling of vehicles (existingtelemetry or dedicated effort) and upload data toFleet DNA website2. Fleet DNA provides drive cycle analysis back todata provider to characterize vehicle use and alsocompares to similar vehicles in data base3. FASTSim (used to perform simulation of entire setof vocational data set) assesses the benefit oftechnology for the user specific data set– Aero improvement– Rolling Resistance– Engine sizing– Transmission options– Mass reduction– Driving behavior– HEV, EV options– Anti-Idle options– Natural Gas and Biofuel optionsUsing the Tools23456784400 High 4400 Low 4900 High 4900 Low T800 High T800 LowHighMassMidMassLowMass+10.1%+11.1% +10.8%+12.8%+8.0%+3.8%Effectof masson fueleconomyy = 2182.6x-2.324R² = 0.753301234560 10 20 30 40 50 60KI(1/mile)Average Driving Speed (mph)School Bus Data Average Driving Speed vs. Kinetic IntensityLake Washington Adams County Schenectedy Power (Aggregate Data)Data subsets representspecific fleet sourcesand locations: howdoes fleet compare tooverall vocation?FASTSim can run alldrive cycles to give a‘range’ of improvementfor each technologychange.
