  1. WLTP-E-Lab Sub GroupProgress reportWLTP-DTP-E-LabProc-043 Leader: Per Ohlund / Kazuki Kobayashi

  2. Meeting(after 62th GRPE) • 11th meeting: Date:5.7.2011 Location: Sweden Topics:Open issues /Validation Parameter Decided the issues concerning validation phase 2 take priority. Calculation portion will be discussed based on validation results. E-Lab sub group will prepare test sequence for validation phase 2 instead of gtr draft. 12th meeting: Date:6.9.2011 Location: Phone meeting Topics: Open issues /Validation phase 2 parameter/Test sequence

  3. Open issues • Green color means “agreed or deleted” • Red color means “to be discussed “. • Blue color means” to be confirmed in Validation phase 2”. • Under line means “changed from last DTP in Geneva”. • These under lined issues will be reported today.

  4. Max ex.15,000 Battery/ICE operation ratio OIL No.6bis Max./min mileage for HEV ICE issue min ex.3,000 NOVC vehicle: Default mode OVC vehicle: Manufacture recommended way Minimum mileage for EV OIL No.6 ICE Run-in mileage [km] 300 Battery Driving schedule ICE issue or durability phase Time (hr)

  5. F(N) Vehicle Warm-up ICE issue Max. speed of RLD ICE issue Tolerance of R/L set ICE issue Dyno. Warm-up ICE issue Dyno/Vehicle speed Vehicle Speed (hr) Time on Dyno. mode ICE issue on Coast down mode OIL No.3bis Need to consider Electrified vehicle issue Dyno. Warm-up Vehicle Setting Vehicle Warm-up Road Load Setting F2F in Bern *) allow battery charging during vehicle warm-up to prevent empty battery

  6. Unknown SOC Cold start of ICE Performance of Watt-hour meter, Am-meter OIL No.15,16,17 Charging Condition Battery [Ah] Validation test

  7. ∆RCB (Ah) Start End CO2/Fuel consumption/(Emission) Cycle EU) ECE101 Annex8 0 Charge(-) ∆RCB (Ah) OIL No.25bis How to measure? Opt.1) Voltage [V] Opt.2) Current [Ah] Opt.3) CAN To be measured by current regulation OIL No.27RCB correction criteria ±x%of fuel energy? Start Discharge(+) RCB Correction for CO2 &FC

  8. OIL.10bis 1hr End of charge criteria Charge complete Plug off Test start (OIL10) Validation test

  9. 1h max from Alternative Fully Charged plug off (in case of charge and CD test has start of CD to be retested) : Charge Depleting Range RCDA ICE Spak precondition time+ battery charge All Electric Range ing at chronologica Equivalent All Electric Range Charging Condition [Ah] l separation from step 1 and 2 First start of ICE Test n Test n+1 Test 1 Test 2 Driving cycle [/] (transcient) (needed for calculations) CO RCDA calculated with k factor 2 Recharge Recharging 12h max 12h max CO avg CD CO Transcient CO hot CS 2 2 2 36h soak max OIL.No31 Low power vehicle What is Low power vehicle? How to validate? To be raised DTP level

  10. Detailed calculation formula is developed based on validation test results. Pollutants : CO2/Fuel Consumption : Range :

  11. 1.0 JPN (EU) US OIL No.1: WLTP UF SAE 1711 with Opt.1) based on reagional data Opt.2) based on worldwide data 0.5 US: SAE J1711 with US data JPN: SAE J1711 with JPN dataEU: CS weight is 25km (fixed) Utility Factor 25 OVCrange (km) To be discussed later stage

  12. E-lab subgroup propose the test sequence instead of complete gtr draft. See attached file. “WLTP-DTP-E-LabProc-042 Test Procedure for validation2 rev.xls”
