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.

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.

September 2015 drafting meeting: To be discussed.

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.

Proposal from W. Coleman: 3.3.14. "Hybrid electric vehicle" means a hybrid vehicle where one of the energy converters is an electric machine.

September 2015 drafting meeting: To be discussed.

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.

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

Definitions, §3

4.1.

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.

September 2015 drafting meeting: adopted.

Task: Approval of the proposed definition.

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.

Task: Text to the right yet to be approved.

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

2.1. rotational masses

September 2015 drafting meeting:

June drafting: Has to be redone. Place on hold. July: still in progress.

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.

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.

2.4. torque meter method. BMW #8

September 2015 drafting meeting: Adopted, text incorporated into the GTR as proposal.

? 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. f0' = c0 / r f1' = c1 / r f2' = c2 / r where: c0, c1, c2 are the running resistance coefficients determined in paragraph 4.4.4. of this Annex, Nm, Nm/(km/h), Nm/(km/h)?; r is 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 CO2 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.

2. and 2.3. torque meter method. BMW #9

September 2015 drafting meeting: Text incorporated into the GTR as a proposal.

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, Fsj, and the target road load, Fs, shall be calculated according to the equations below, at each reference speed, vj: << formulas from Appendix 1 >> 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 vj. 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.

Is the number of points also not necessary?

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

September 2015 drafting meeting: No equation necessary. Adopted.

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).

Task: Clarification of 7.2.1.2. is required. Possible interpretation on the next slide.

September 2015 drafting meeting: remains open until task force meeting on September 16.

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

nnex 5, §7.2.1.2. Sampling for N20

Page 2 of 2

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: The dilution air bag for each phase, or From the dilution air bag of phase 1 only, or From a single composite dilution air bag

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 ?

Is the unit in Flow_lost_max m? or smaller units, such as litres, which may account for the 0.005 in the equation?

September 2015 drafting meeting: adopted. Unit is m?.

Comment ADAM: the unit is the same as for Vmix, m3.

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)

Annex 6, Appendix 2, Test procedure for electric power supply system monitoring

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).

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.

WLTP GTR Drafting Issues Annex 6, Appendix 2, §2

1.1. RCB correction, measurement tolerance. BMW #11

September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals.

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).

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%.

WLTP drafting, Annex 6, Appendix 2, 1. General Battery SOC correction

September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals.

Current text: Annex 6, Appendix 2

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?
