1 September 2015 Drafting Subgroup Audio/Web Meeting 106.10.2015 WLTP-12-13e

2 206.10.2015 These slides are based on the status of the GTR as of late August/early September, 2015. The set of slides includes those submitted by BMW and the additional pollutants task force.

3 I. Statement of technical rationale and justification 306.10.2015

4 4 September 2015 drafting meeting: Entire sentence deleted. Introduction, paragraph 5 OPEN POINT: 5. March 2015 drafting meeting. Japan proposes deleting the whole sentence or delete "fuel cells".

5 II. Text of the global technical regulation 506.10.2015

6 6 September 2015 drafting meeting: n/v remains; ndv (= n divided by v) remains. (d) n/v ratios (engine rotational speed divided by vehicle speed). This requirement shall be considered fulfilled if, for all transmission ratios concerned, the difference with respect to the transmission ratios of the most commonly installed transmission type is within 8 per cent; Text from H. Steven: Task: Harmonisation in the use of n/v throughout the GTR II. 5. General requirements, Interpolation family §5.6.1., 5.6.3., 5.7.

7 706.10.2015 September 2015 drafting meeting: will be reviewed during the next EV sessions. Task: The paragraph must be reviewed, especially concerning the references to the UN Regulations. II. 5. General requirements, §5.6.2. Interpolation family for NOVC-HEVs and OVC-HEVs

8 806.10.2015 September 2015 drafting meeting: will be reviewed during the next EV sessions. 5.6.3.(g) also rewritten to harmonise with 5.6.1.(d) Task: The paragraph must be reviewed, especially concerning the references to the UN Regulations. II. 5. General requirements, §5.6.3. Interpolation family for PEVs

9 906.10.2015 September 2015 drafting meeting: EV yet to discuss this. Task: Text proposal expected (M. Nägeli) II. 5. General requirements, §5.7. Road load family

10 II. 3. Definitions 1006.10.2015

11 Definitions (mass) §3.2.d. PROPOSAL: 3.2.d."Test mass of the vehicle" means the sum of the actual mass of the vehicle, 25 kg and mass representative of the vehicle load. 1106.10.2015 September drafting meeting: the first 3.2.d. in the gtr is adopted. JPN: we thought it was decided like, 3.2.d.“Test mass of the vehicle” means the sum of the mass of the vehicle in running order and its actually fitted optional equipment plus 25 kg and the mass representative of the vehicle load;

12 WLTP GTR DRAFTING ISSUES TEXT OF GTR, DEFINITIONS, § 3.2.14. BMW #1 WLTP Drafting, BMW, 18.08.2015 Justification:  "simulated" is only used in the context of simulating road load on a chassis dyno and refers to the total road load, the vehicle is exposed to on a dyno (RR and drivetrain losses of the vehicle plus applied force by the chassis dyno).  Definition unclear  improve. Change text: "Simulated road load" means the road load applied to the vehicle on a chassis dynamometer and is the sum of the losses of the vehicle itself plus the applied force of the dynamometer. September 2015 drafting meeting: Currently being discussed in the road load task force; still under review.

13 WLTP GTR DRAFTING ISSUES TEXT OF GTR, DEFINITIONS, §3.5.8. BMW #2 WLTP Drafting, BMW, 18.08.2015 Justification:  "Modes" that do not effect emissions should not be considered (e.g. "night mode" of dashboard). Change 3.5.8.: 3.5.8."Mode" means a distinct driver-selectable condition which affects emissions, or fuel or energy consumption. September 2015 drafting meeting: Appears not to have been wrapped up.

14 Definitions, §3.3.10. Current GTR Text: 3.3.10. "Energy storage system" means the part of the powertrain on board a vehicle that can store chemical, electrical or mechanical energy and which can be refilled or recharged externally and/or internally. 14 Proposal from W. Coleman: 3.3.10. "Energy storage system" means the part of the powertrain on board a vehicle that can store chemical, electrical or mechanical energy and release it in the same form as it was input which can be refilled or recharged externally and/or internally. 06.10.2015 September 2015 drafting meeting: To be discussed.

15 Definitions, §3.3.14. GTR Text: 3.3.14. "Hybrid electric vehicle" means a vehicle using at least one fuel consuming machine and one electric machine for the purpose of vehicle propulsion. 15 Proposal from W. Coleman: 3.3.14. "Hybrid electric vehicle" means a hybrid vehicle where one of the energy converters is an electric machine. 06.10.2015 September 2015 drafting meeting: To be discussed.

16 Definitions, §3.3.xx. GTR Text: 3.3.xx. "Hydrogen fuel cell vehicle" means a vehicle powered by a fuel cell that converts chemical energy from hydrogen into electric energy, for propulsion of the vehicle. 1606.10.2015 September 2015 drafting meeting: To be discussed. Task: Approval of the definition. (identical to the definitions in ECE-R 101 and ECE-R 83)

17 Definitions, §3.4.1. 1706.10.2015 September 2015 drafting meeting: adopted. Current GTR: 3.4.1. "Manual transmission" means a transmission where gears are shifted by hand in conjunction with a manual disengagement of a clutch. Proposed definition (A. Feucht): 3.4.1. "Manual transmission" means a transmission where gears can only be shifted by action of the driver. Reasoning: There are vehicles (smart, A2,…) where gears can only be shifted by action of the driver but where no manual disengagement of the clutch is necessary because the clutch is automated. Task: Approval of the proposed definition.

18 Annex 1 WLTC 18March 22, 2015

19 Page 19 WLTP DRAFTING, ANNEX 1 WLTC DIAGRAMS BMW #4  Change diagrams, that the start and end exactly at the phase limits (see arrows).  Or: Change text, that it takes the table as the only valid reference and the diagrams just as "information". Old text: Annex 1 WLTP Drafting TF, BMW, 19.06.2015 September 2015 drafting meeting: Have been sent, have yet to be incorporated.

20 WLTP GTR DRAFTING ISSUES ANNEX 1, DOWNSCALING, ADDITIONAL PROVISIONS, §8.4.2. BMW #5 WLTP Drafting, BMW, 18.08.2015  Should provision for capped speed of electrified vehicles be used as well for ICE vehicles? September 2015 drafting meeting: still under discussion.

21 Annex 2 Gear selection, shift point determination 2106.10.2015

22 WLTP GTR DRAFTING ISSUES ANNEX 2, §2.(H), GEARSHIFTING. BMW #6 WLTP Drafting, BMW, 18.08.2015  Clearly define the source of the used full load curve.  The full load curve shall be part of the approval (if not already).  Is the application of R85 a regional issue or can be referred to R85 within the GTR? Add sentence in paragraph 2. of Annex 2:...equally spaced. The power curve shall be determined according to Regulation No. 85. If the required data sets (n, P wot ) are not included already, they shall be added to the [regional] approval according to Regulation No. 85. September 2015 drafting meeting: see comments from Japan on the next slide.

23 WLTP GTR DRAFTING ISSUES ANNEX 2, §2.(H), GEARSHIFTING. BMW #6 WLTP Drafting, BMW, 18.08.2015 September 2015 drafting meeting: Comments from Japan adopted. JPN: Better to be in line with definition 3.7.1. (i.e. add “current regional regulation” to proposal, or delete “current regional regulation” from 3.7.1.) 3.7.1. "Rated engine power" (Prated) means maximum engine power in kW as per the certification procedure based on current regional regulation. In the absence of a definition, the rated engine power shall be declared by the manufacturer according to Regulation No. 85.

24 2406.10.2015 Task: Clarification of the highlighted text. Within a period of 5 minutes, the vehicle, having the mass defined in the equation below, shall be able to pull away from standstill on an uphill gradient of at least 12 per cent in 2nd gear on five separate occasions, pulling away within 4 seconds on each occasion. Gear selection, §2.(j)(e) September 2015 drafting meeting: Basically accepted but Rob Gardner to check the wording.

25 2506.10.2015 Gear selection, §2.(j)(e) JPN: Definition of gross train mass or gross vehicle mass or max. trailer mass are missing. The definition of 1230/2012 could be used. (8) ‘technically permissible maximum laden mass of the combination’ (MC) means the maximum mass allocated to the combination of a motor vehicle and one or more trailers on the basis of its construction features and its design performances or the maximum mass allocated to the combination of a tractor unit and a semi- trailer; (9) ‘technically permissible maximum towable mass’ (TM) means the maximum mass of one or more trailers that may be towed by a towing vehicle which corresponds to the total load transmitted to the ground by the wheels of an axle or a group of axles on any trailer coupled to the towing vehicle; September 2015 drafting meeting: Adopt (8) but not (9). Correlate with GTR j.(5). Already in the GTR as a definition.

26 Annex 4 Road load and dynamometer setting 2606.10.2015

27 2706.10.2015 September 2015 drafting meeting: R. Cuelenaere to resend mails to these subjects. DC to incorporate accordingly. Information: The Annex 4 Task Force is reviewing all of Annex 4 but it has been requested to examine at the request of DC paragraphs 4.2.1.7.3.; 4.3.1.3.2.; 4.3.1.3.4.; 4.3.2.6.6.; 4.5.5.1.; 8.1.3.2.1.; and 1.1., 1.2. and 2.2. of Annex 4, Appendix 1.

28 WLTP GTR DRAFTING ISSUES ANNEX 4, §3.2. WIND TUNNEL CRITERIA. BMW #7 WLTP Drafting, BMW, 18.08.2015 Delete text below 3.2. 3.2.Wind tunnel criteria  All parts of the GTR using the criterion, are describing very clear for what and how to use them (see below).  The current sentence is even wrong, because now used for wind tunnel method as well. September 2015 drafting meeting: Text below 3.2. deleted. Introductory sentence added. See gtr.

29 Page 29 WLTP DRAFTING, ANNEX 4, §3.2.8. WIND TUNNEL CRITERIA, CP  Request of Japan, to define height.  It is not correct, to measure +/-2 meters to the balance center, as this would be not the criteria to be checked (has to be the vehicle!). Old text: Annex 4, 3.2.8. New text: Annex 4, 3.2.8., "cp" The absolute difference of the pressure coefficient, cp, over a distance 2 metres ahead and 2 metres behind the vehicle and at a height of the center of jet shall not deviate more than ± 1 per cent WLTP Drafting TF, BMW, 19.06.2015 Task: Text to the right yet to be approved. September 2015 drafting meeting: Blue box approved. 2 per cent in the equation replaced by 0.02. Reference to “per cent” in the text above it also replaced.

30 WLTP GTR DRAFTING ISSUES ROAD LOAD, §4.2.1.3.3. BMW #3 WLTP Drafting, BMW, 18.08.2015 Put new sub-paragraphs at the sentences shown 4.2.1.3.4.Energy range and transmission worst case 4.2.1.3.5.Calculation of H and L of interpolation family September 2015 drafting meeting: Adopted, GTR modified accordingly.

31 Annex 4, Road load, §7.2.1. Inertia mass setting (page 1 of 2) 06.10.2015 September 2015 drafting meeting: Use version 6 as benchmark but 7.2.1. is still not complete. A. Feucht to make a concrete proposal. 31 Task: Section to be reviewed (During June drafting meeting:, C. Lueginger offered to review the section)

32 3206.10.2015 Annex 4, Road load, §7.2.1. Inertia mass setting (page 2 of 2) EXPERT PROPOSAL: June drafting meeting: approval of the text in yellow and red. C. Lueginger to review this section Task: Section to be reviewed (During June drafting meeting, C. Lueginger offered to review the section)

33 Page 33 WLTP DRAFTING, ANNEX 4, §7.2.1. ROTATIONAL MASSES  Adding 1.5 % not depending on the dyno directly, but on the situation, that one axle is not taken into account. So also on a two axle dyno driven with one axle only.  Proposal shall consider of any case, that 1.5% are added in the case one axle is not considered for inertia. Old text: Annex 4 New text: Annex 4 7.2.1. Inertia mass setting The equivalent inertia mass of the chassis dynamometer shall be set to the test mass if a dual-axis chassis dynamometer is used. In the case that: (a) a single-axis chassis dynamometer is used; (b) a dual-axis chassis dynamometer where only one axle is used for representing the inertia; the equivalent inertia mass shall be increased either by the equivalent effective mass of the standing wheels or by 1.5 per cent of the sum of the mass in running order and 25 kilograms. If the chassis dynamometer is not capable to meet the inertia setting exactly, the next higher inertia setting shall be applied with a maximum increase of 10 kg. WLTP Drafting TF, BMW, 19.06.2015 June drafting: Has to be redone. Place on hold. July: still in progress. September 2015 drafting meeting:

34 WLTP GTR DRAFTING ISSUES ANNEX 4, §8. CHASSIS DYNO SETTING. BMW #10 WLTP Drafting, BMW, 18.08.2015 Change 8.1. 8.1.Chassis dynamometer setting by the coastdown method This method is applicable when f0, f1, f2 values (N, N/(km/h), N/(km/h)²) have been determined.  "Normal" chassis dyno setting to be applied not only in the case of coast down testing, but also for wind tunnel testing, calculated values, extrapolation method or torque meter method, if f0, f1, f2 values have been determined.  The text should reflect, that this method is applicable, if "normal" road load values are available. September 2015 drafting meeting: proposed change adopted. Text incorporated in GTR as proposal.

35 WLTP GTR DRAFTING ISSUES ANNEX 4, §8.2.4. TORQUE METER METHOD. BMW #8 WLTP Drafting, BMW, 18.08.2015  New first paragraph in 8.2.4. 8.2.4.If the vehicle does not coast down in a repeatable manner and a coast down mode according to paragraph 4.2.1.7.5. is not feasible, the determination as well as the use of f0, f1, f2 values may be omitted and paragraph 8.2.4.1. applies. In any other case the procedure described in paragraphs 8.2.4.2. to 8.2.4.3. shall be performed. 8.2.4.1. f 0 ' = c 0 / r f 1 ' = c 1 / r f 2 ' = c 2 / r where: c 0, c 1, c 2 are the running resistance coefficients determined in paragraph 4.4.4. of this Annex, Nm, Nm/(km/h), Nm/(km/h)²; ris the dynamic tyre radius of the vehicle with which the running resistance was determined, m. The determined f0', f1', f2' values shall not be used for a chassis dynamometer setting or any emission or range testing. They shall be used only in the following cases: (a) determination of downscaling, paragraph 8. of Annex 1; (b) determination of gearshift points, Annex 2; (c) interpolation of CO 2 and fuel consumption, paragraph 3.2.3 of Annex 7; (d) calculation of results of electrified vehicles, paragraphs TBD.  Move that paragraph to 8.2.4.2.: Once the chassis dynamometer has been set within the specified tolerances, a vehicle coastdown shall be performed on the chassis dynamometer as outlined in paragraph 4.3.1.3. The coastdown times shall be recorded.  Shift following paragraphs by one: 8.2.4.1. .2 and.2 .3.  Downscaling, gearshifting and interpolation method need f0, f1, f2 values, which are normally available also from the torque meter method.  In the case, that the vehicle cannot be coasted down under any reasonable condition, we need a fallback solution.  The proposed formula will be a worst case approach for (a) and (b) and is equivalent to "normal" f0f1f2 for (c) and (d). September 2015 drafting meeting: Adopted, text incorporated into the GTR as proposal.

36 WLTP GTR DRAFTING ISSUES ANNEX 4, APPENDIX 1, §2.2. AND 2.3. TORQUE METER METHOD. BMW #9 WLTP Drafting, BMW, 18.08.2015  Move these two formulas to paragraph 8.2.3.2.  Explain the formulas better (what are the variables). It is intended to compare the simulated road load of the dyno with the target road load on the basis of a force.  Having done that, Appendix 1 appears to be not used any more and can be deleted. Paragraphs 2.2. and 2.3. of Appendix 1 of Annex 4:8.2.3.2.The simulated road load, F sj, and the target road load, F s, shall be calculated according to the equations below, at each reference speed, v j : > The simulated road load shall be within a tolerance of ± 10 N from the target road load, in the specified speed ranges, at each reference speed v j. If the tolerance at any reference speed does not satisfy the criterion of the method described in this paragraph, paragraph 8.2.3.3. below shall be used to adjust the chassis dynamometer load setting. September 2015 drafting meeting: Text incorporated into the GTR as a proposal.

37 Annex 5 Test equipment and calibrations 3706.10.2015

38 3806.10.2015 September 2015 drafting meeting: No equation necessary. Adopted. Annex 5, Table A5/1 and §4.2.2.2. Linear response of an analytical balance It was agreed to refer to the intercept as a0 and the slope as a1, but is an equation required in the form of y = mx +b, i.e. measured mass = a0 + a1 × actual mass Is the number of points also not necessary? Comment ADAM: In the paragraph above is written that „at least 4 equally-spaced reference weights shall be tested“. There is also mentioned that linear regression is applied. Therefore, an equation is not required. These modifications are approved by B. Giechaskiel (JRC).

39 3906.10.2015 September 2015 drafting meeting: Remains as "is" Annex 5, §7.1.1. Laser Diode Spectrometer (LDS) or Quantum Cascade Laser (QCL) Comment ADAM: noLH – Agreed : the absorption line is chosen

40 Annex 5, §7.2.1.2. Sampling for N 2 0 4006/10/20154006.10.2015 September 2015 drafting meeting: remains open until task force meeting on September 16. Task: Clarification of 7.2.1.2. is required. Possible interpretation on the next slide. Page 1 of 2 Comment ADAM: I try to clarify it. For each WLTC-phase one exhaust bag has to be filled -> 4 bags. For each WLTC-phase one dilution air bag has to be filled -> 4 bags; in total 8 bags Alternatively, it is sufficient to use the dilution air bag from WLTC_phase1 -> 1 bag; in total 5 bags or one dilution air bag sampled over the whole WLTC -> 1 bag; in total 5 bags

41 Annex 5, §7.2.1.2. Sampling for N 2 0 4106/10/201541 September 2015 drafting meeting: Does this mean, that only 5 bags are required? Or, are 9 bags required? Why is this any different from the number of bags required for all other compounds? Possible rewording as Dubuc/Coleman understand the paragraph: During each phase of the test, a gas sample shall be taken for analysis from the corresponding diluted exhaust bag. Additionally, a gas sample shall be taken from one of the following sources: 1. The dilution air bag for each phase, or 2. From the dilution air bag of phase 1 only, or 3. From a single composite dilution air bag Page 2 of 2 Comment ADAM: see previous slide LH : this is to reduce the amount of time spent for the GC-MS and is similar to that applied for impinger and cartridge. For good practice, I think it should be individual phase bags for dilution air or 1 bag taken over the entire test ? Though in reality, the background N2O should be very stable given its sources in the atmosphere ?

42 4206.10.2015 September 2015 drafting meeting: adopted. Unit is m³. Annex 5, §7.1.2.5. NH 3 measurement Is the unit in Flow_lost_max m³ or smaller units, such as litres, which may account for the 0.005 in the equation? Comment ADAM: the unit is the same as for V mix, m 3. LH : the maximum lost amount of exhaust gas is 0.5% of the total exhaust volume per phase as calculated from Vmix and the DF. The result is in m3/phase (this test is still from the calculations from Moersch I presume that he used m3 to be keep same units of the dilution tunnel. Leave it as it is)

43 Annex 5, §7.3.1.7.1. Sampling for Ethanol 4306/10/20154306.10.2015 September 2015 drafting meeting: Will be rewritten by Cova task force. Task: What happens if you are above the LoD? Also, for how many weeks, i.e. how long? Comment ADAM: delete the sentence „ The ethanol… proceed“; a weekly blank run is necessary as long as the Ethanol analysis is carried out. LH : A blank sampling run should have been taken within one week of the test ?

44 Annex 5, §7.3.1.9. Sampling for Ethanol 4406/10/20154406.10.2015 September 2015 drafting meeting: Adopted. Task: Propose to change the title to : Calculations for GC from impingers and from diluted gas. Agreed? Comment ADAM/all: agreed

45 Annex 5, §7.3.1.9. Sampling for Ethanol 4506/10/20154506.10.2015 September 2015 drafting meeting: adopted. Text to be received from Cova. Task: 1. There is no 7.3.1.8. Should 7.3.1.9. become 7.3.1.8.? 2. Can it be confirmed that 7.3.1.9. is a title? 3. If so, can the titles in 7.3.1.10. and 7.3.1.11. be eliminated but the text "The limits…" and "Interference and…" be retained? Comment ADAM: 1. yes 2. I think that should be deleted from there 3. no

46 Annex 5, §7.4.1.4.2.1. Analysis for formaldehyde and acetaldehyde 4606/10/20154606.10.2015 September 2015 drafting meeting: Clarified. Filter paper must not be defined. Task: Should the grade of filter paper be clarified? Comment ADAM: No. The last sentence can be deleted as is seems to be a copy/paste error. Acrolein is not a target compound

47 Annex 6 Type 1 test procedure and test conditions 4706.10.2015

48 Annex 6, Test Procedure, §1.2.6.7.4. 4806/10/20154806.10.2015 September 2015 drafting meeting: Add in Annex 1: the tables describe the speed trace. "….until the vehicle speed reaches the respective target speed again."

49 Annex 6, Appendix 2, Test procedure for electric power supply system monitoring 49 EXPERT PROPOSAL: 29.07.2014: Dr. Ligterink (TNO) and his colleague, Gerrit Kadijk, highlights inconsistencies within the GTR concerning units used in Annex 6, Appendix 2 (Test procedure for electric power supply system monitoring). The problem is whether (a) kW.h, joules or megajoules should be used in equations, and, (b), whether kW.h, joules or megajoiules should be used in the Willans factors, and (c) whether the equations are all correct. This applies also to Annex 7 (Calculations) and to Annex 8 (Evs). 06.10.2015 September: For electric energy, use kWh in Annex 8 and in Annex 6 App. 2. Conclusion: Annex 8 task force agenda? Niikuni-san to add this to Sept. 11 EV audio/web. Drafting Co.: contact UN ECE regarding the use of SI units. Comment: Should remain flexible even if UN ECE says that joules/MJ should be used, i.e. use kWh where appropriate. Page 1 of 2

50 GTR Text: Should energy content of fuel be in, megajoules, Wh or kWh? 50 Consistency in the use of MJ or other units 06.10.2015 April IWG/drafting meeting (Stockholm): Rob Cuelenaere to investigate. Page 2 of 2

51 5106.10.2015 September 2015 drafting meeting: H. Schmidt and K. Kolesa confirm that the text was approved in Pune. GTR amended accordingly. Annex 6, Appendix 1, Test procedure periodically regenerating systems, §1. General OPEN POINT: Was it agreed that this text is to be included under §1. General?

52 5206.10.2015 September 2015 drafting meeting: H. Schmidt and K. Kolesa confirm that the text was approved in Pune. GTR amended accordingly. Annex 6, Appendix 1, Test procedure periodically regenerating systems, §2. OPEN POINT: Was this text adopted?

53 5306.10.2015 September 2015 drafting meeting: contact Nick-san. Annex 6, Appendix 1, Test procedure periodically regenerating systems, §3.1.1. EXPERT PROPOSAL: This paragraph was to have been checked by N. Ichikawa. Is the paragraph adopted?

54 WLTP GTR DRAFTING ISSUES ANNEX 6, APPENDIX 2, §1. RCB CORRECTION. BMW #12 WLTP Drafting, BMW, 18.08.2015  Is it clear enough, that if the vehicle has more than one battery: - all batteries are measured; YES - the threshold refers to the sum; - the correction is calculated using the sum of all Delta-RCBs of all batteries?  If not, whole Appendix 2 should be checked, as well as references in Annex 6 test.  Is the definition of battery / REESS clear? Is plus/minus energy in/out clear? Current text: Annex 6, Appendix 2 September 2015 drafting meeting: follow progress of Annex 8, App. 2 and match this appendix accordingly.

55 WLTP GTR DRAFTING ISSUES ANNEX 6, APPENDIX 2, §2.1.1. RCB CORRECTION, MEASUREMENT TOLERANCE. BMW #11 WLTP Drafting, BMW, 18.08.2015 Change text regarding tolerance in: 2.1.1. The battery current shall be measured during the tests using a clamp-on or closed type current transducer. The current transducer (i.e. a current sensor without data acquisition equipment) shall have a minimum accuracy of 0.1 per cent of full scale, and the full scale shall be selected within the maximum electric load and the maximum load + 50%.  There are two solutions:  (1) Exclude current of starting the engine: - small energy error; - measurement accuracy can be maintained; - risk of wrong application (which wire to measure?).  (2) Increase tolerance; no error in balanced energy; slightly lower accuracy; no risk of wrong application.  Favourite is option (2), which is reflected in the text. Example average current, lower average current, higher peak current current [A]515>200 tolerance [A] to measured value 0.0250.0751.000 tolerance [A] to full scale of 200 0.2  Electric current cannot be measured with that accuracy, because: - taking an accurate instrument, it will be magnetized and therefore will have an offset with the first engine start (too high currents); - taking an instrument for high currents, cannot be that accurate.  Tolerance on the measured value is not a technical correct tolerance, only full scale tolerance is valid (while limiting the full scale). September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals.

56 Page 56 WLTP DRAFTING, ANNEX 6, APPENDIX 2, 1. GENERAL BATTERY SOC CORRECTION  Is it clear enough, that if the vehicle has more than one battery: - all batteries are measured; - the threshold refers to the sum; - the correction is applied to the sum of all Delta-RCBs of all batteries?  If not, whole Appendix 2 should be checked, as well as references in Annex 6 test.  NEW: Is the definition of battery / REESS clear? Is plus/minus energy in/out clear? Current text: Annex 6, Appendix 2 WLTP Drafting TF, BMW, 19.06.2015 September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals.

57 5706.10.2015 September 2015 drafting meeting: Change all to all REESSs. GTR modified accordingly. Annex 6, Appendix 2, Test procedure for electric power supply system monitoring OPEN POINT: For all vehicle batteries?

58 5806.10.2015 September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals. Annex 6, Appendix 2, §2. Measurement equipment and instrumentation OPEN POINT: …current(s)…?

59 Annex 7 Calculations 5906.10.2015
