Lab process-EV meeting in Brussels
• 26-28th of March at JAMA office in Brussels.• Discussion for the gtr text based on ACEA
proposal. • Some open issues should be evaluated during
validation phase 2.• The draft gtr ver.1 should be submitted to
drafting coordinator.• This result will be referred to Validation test
sequence by beginning of May.
2.2.2. Hybrid Electric PowertrainHybrid electric power train means a power train that, for the
purpose of mechanical propulsion, draws energy from both of the following on-vehicle sources of stored energy/power:
- Consumable fuel- RESS [1]) 1) Rechargeable energy storage system (RESS) means the
rechargeable energy storage system that provides electric energy for electric propulsion (e.g.: battery, capacitor, flywheel / generator ...). <<ECE101 base modified >>
RESS renamed REESS(REchargeable Energy Storage System. Refer to R100.

5.1.1.7.1.Charge Depleting test: Option 1: For testing vehicles with operator selectable driving modes, the CD test shall be
performed by using the most electric energy consuming hybrid operation mode that best match the target curve.
In case that the most electric energy consuming hybrid mode that best match the target curve is the default mode, the test can be performed in the default mode.
Option 2: For testing vehicles with operator selectable driving modes, the CD test shall be
performed by using the most electric energy consuming hybrid operation mode that best match the target curve.
In case that the most electric energy consuming hybrid mode that best match the target curve is the default mode, the test can be performed in the default mode.
Option 3: For testing vehicles with the default mode position as operator selectable driving modes,
the CD test shall be performed by using the default mode. In case that vehicle has not the default mode, manufacturer may recommend the most
representative mode that best match the target curve and most customers will use on the road to the type approval authority, the test can be performed in the approved mode.

Soak time:12 hr or more, less than 36hr.Chargingtime: Stop with full charged. 4.5.The Lab-process group has decided to have 2alternatives for the soak time:Alt 1: This conditioning shall be carried out for atleast six hours and continue until the engine oiltemperature and coolant, if any, are within ±2 K ofthe set point temperature of the room. At therequest of the manufacturer, forced cooling downcould be used with open bonnet, appropriate use ofcooling fan.Alt.2: This conditioning shall be carried out at least12 hours and maximum 36 hours, with closedbonnet in soak area environment without using afan. So, before the test CD test for EV and OVC HEV,we propose to keep the choose between bothoptions during the soak time with specific provisionfor the charge of the battery

25 Tec OIFor detection of CScondition : RCBbreak off criteria
1) ACEA and JAMA agree on the principle toperform n+1 test sequence to confirm the end ofCD test and define the transient cycle as the test n.If the battery energy used during each testsequence is less than a certain value [to be definedin % of fuel consumption], so the cycle before (testn) is the transient one. As an option, the fuelconsumption value of the test sequence x could becompared to the fuel consumption measured at CStest.2) Definition of the break off criteria :ACEA proposal : absolute NEC* as a % of cycleenergy demand or % of total energy used (to bediscussed)* NEC = Net Energy Change = RCB x nominalvoltage of RESS(Proposal to be checked : the test is considered to be ended as soon as NEC during the cycle is less than [3%] and the absolute energy comsumed is less than [10 Wh]) Japan proposal ?
Actions : 1) method to be developed todetermine the cycle energy demand and then todefine the value ; 2) to check Renault's proposal(26/05/2011) and to reformulate it if any. (The[values] are given as an indication but have tobe well defined)

JAMA and ACEA agree to only correct CO2 andfuel consumption. No relevance for pollutantemissions because no relationship between RCBand pollutant emisisons
Tests related to CO2 correction factorelaboration are used to show that polluantemissions comply with the limit values and norelationship with RCB. So, it means that specifictests should not be required for certification test.The non relationship between RCB andpollutants emission can be showed withmanufacturers internal data associated to theCO2 measurements

Need for a clarification regarding statement fromACEA and JAMA. Both agrees that there is no needfor pollutants emission correction unless there isevidence for a correction. Remark from ACEA thereis the Matador study that could give clarity for theneed of a correction. Japan is of the opinion thatsince there is correction for CO2 there is no extraburden for the manufacturer and that correction forcritical emissions could be applied.Comment from Japan, additional pollutants will beregulated in the WLTP process. The Japanesegovernment will require to show to influence ofdifferent RCB.
