  4. 2. Summary of Applicable Test Cycles LetterNumber PhaseClass New Proposal L3 + M3 + H3 (+ ??) L3 + M3 + H3 (+ eH3) L3 + M3- + H3- issue-1 issue-2 34 Power* to Mass** Ratio (kW/t) L2 + M2 + L2 L2 + M2 + H2 L2 + M2 + H2 (+ eH2) 22 L1 + M1 + L1 L1 + L1 + L1 ～ ～ 120 90 70 135 Maximum Vehicle Speed *** (km/h) *) 30 minutes maximum power for Battery **) Curb Mass ***) 30 minutes maximum speed for BEV

  5. 3. Issues to be Discussed for Applicable Test Cycle 1. Adoption of new cycle (Class3-) (1) Necessity of Class3- Category and Impact of Class3- Cycle -- refer DHC14-03 (2) Cycle Time Table ------ upload to JRC server 2. Exemption of Ex-High phase (1) Threshold of maximum vehicle speed (2) Alternative cycle for Ex-High phase (3) CP needs

  6. 4-1. Sampling Method <conditions for Mode construction> critical disadvantage advantage × ○ *) Ex-H phase shall be exempted when vehicle maximum speed is less than [xyz] km/h or CP needs

  7. 4-2. Proposed Mode Construction [ Baseline test - Cold start -] exempt for vehicles whose maximum speed is equal or less than [xyz] km/h or CP option LOW 589s MIDDLE 433s HIGH 455s Ex-HIGH 323s soak Sample#1 RCB#1 Sample#2 RCB#2 Sample#3 RCB#3 Sample#4 RCB#4 [ Baseline test - Hot start -] PM shall be analyzed with one filter LOW 589s MIDDLE 433s warm up Necessity of hot start test will be decides based on validation 2 results Sample#1 RCB#1 Sample#2 RCB#2 Each CP shall provide COLD/HOT weighting factor cold/hot weighting phase data phase data phase data phase data standalone Can be combined, as an option

  8. 4-3. Proposed Mode Construction [ Range tests ] LOW 589s Charge Batteries Charge Batteries MIDDLE 433s Charge Batteries Charge Batteries Can be combined, as an option HIGH 455s Charge Batteries Charge Batteries Ex-HIGH 323s Charge Batteries Charge Batteries standalone exempt for vehicles whose maximum speed is equal or less than [xyz] km/h or CP option Sample#n * RCB#n Cumulative Whr Cumulative Whr As an option, allow to apply SAE method to get each phase Range for BEV LOW 589s MIDDLE 433s HIGH 455s Ex-HIGH 323s Steady Speed Charge Batteries Charge Batteries Sample#1 RCB#1n Sample#2 RCB#2n Sample#3 RCB#3n Sample#4 RCB#4n Cumulative Whr Cumulative Whr

  9. 4-4. Ki Determination Ex-H phase Ki : allow to use H phase Ki As an option, allow to conduct Ex-H Ki determination • Test without regeneration • each of L ~ H - Loading cycle Test with regeneration Start of regeneration LOW 589s MIDDLE 433s HIGH 455s LOW 589s MIDDLE 433s HIGH 455s LOW 589s MIDDLE 433s HIGH 455s 1 2 ・ ・ ・ n Sample#1 Sample#2 Sample#3 LOW 589s MIDDLE 433s HIGH 455s PM shall be analyzed with one filter Under regeneration ・ ・ ・ End of regeneration Enormal･LOW(g/km) DLoad (km) (including test distance) LOW 589s MIDDLE 433s HIGH 455s Sample#1 Sample#2 Sample#3 <Example of additive Ki factor for Low phase> Eregen･LOW(g/km) = ∑ Mregen･LOW (k) / DLOW *n Dregen (km) ( Enormal･LOW * DLoad + Eregen･LOW * Dregen ) Ki = n - Enormal･LOW*(DLoad+ Dregen) k=1

  10. 4-5. RCB Compensation Factor for only CO2 and FC Hot factor for ALL phases Cold factor for LOW and MIDDLE phases preconditioning preconditioning LOW 589s LOW 589s LOW 589s LOW 589s Overnight soak Set SOC at several level MIDDLE 433s MIDDLE 433s MIDDLE 433s MIDDLE 433s Set SOC at several level HIGH 455s Sample RCB HIGH 455s Sample RCB Ex-HIGH 323s Ex-HIGH 323s As an option, consider no compensation when RCB in each phase is less than [abc] %  depends on E-Lab. sub-group discussion exempt for vehicles whose maximum speed is less than [xyz] km/h or CP option Sample RCB

  11. 5. Next Actions Conjunction with DTP Close All Open Issues Draft gtr / Outline of Technical Report Preparation Conventional Vehicles Electrified Vehicles Start confirmation and Round-Robin test R/L determination Initial analysis Final analysis

  12. 6. Next Meeting Next 15th DHC meeting will be set around middle of December 2012 at [ Place ]. Main agenda items are Fix Cycle Profile and Mode Construction Preparation for next GRPE @ Geneva Detailed information will be noticed by [ Day Month ] 2012. Comments shall be sent to Mr. Ichikawa, Technical Secretariat; nick@ichikawa.tec.toyota.co.jp
