1. WLTP-14-16e
Report from EVE 18 – Shanghai, April 11th/12th Subgroup EV meeting – Paris

2. IWG EVE discussed topics EVE 18 – Shanghai/China – April 11th/12th
System Power Determination ( collaboration with IWG WLTP)
Battery performance and durability ( collaboration with IWG WLTP)
Method of stating energy consumption
Battery Recyclability
Basis Template

3. Determination of System Power for EVs Germany/Korea
 Topic with close Collaboration with WLTP Subgroup EV
Presentation of the current status of the TF system power activities (EVE-18-07e)
Output from the TF-web-audio-meetings in between EVE-17 meeting in January and EVE-18 meeting
8 key elements had been identified which needs further discussions:
Basic requirements to a new regulation
Methodologies
Application of the methodology on HEV system layouts and control strategies
Required input data, required output data
Operating points where the test should be conducted
Load collectives and maximum power applied during the test
Customer information
Application of the methodology on PEVs and FCHVs
Next steps (recommendation):
IWG EVE will recommend a tentative work program for addendum to GTR 15 (estimated to be a 2-3 year project)
Tentative work program with the following priorities:
Step 1: Covering of the WLTP purposes (to be able to apply the cycle classification and the downscaling methodology)
Step 2: Customer Information (information sharing topic for now, will be further evaluated on information level during Phase 1)

4. Battery Performance and durability USA/Canada
 Topic with close Collaboration with WLTP Subgroup EV
Presentations:
Presentation of the updated EVE-report for Part A (EVE-18-10, already including feedback from OICA)
Feedback deadline for EVE-18-10: end of April 2016
Update-Report on vehicle/battery performance and durability (discussed already in EVE-16 and EVE-17)
Overview about the latest activities within the EVE group and FEV (preparing report on battery aging on behalf of US EPA)
Example matrix of durability requirements
Possible options to move forward
Presentation of JP position (EVE-18-12) on battery performance and durability
JP position is that IWG EVE’s future work should focus on vehicle performance and durability, not only battery
Review of FEV report (EVE-18-04)
USA: report is primarily intended to be used as a document which is collecting information which helps in understanding the aging processes in current battery technologies
Report should show that we are just at the beginning of understanding the battery chemistry and that there is still a long way to go

5. Battery Performance and durability USA/Canada
 Topic with close Collaboration with WLTP Subgroup EV
Prerequisites:
WLTP needs to provide EVE with expectations of performance requirements
Durability is to be considered in connection to effects on emissions, not directly life expectancy of battery
Conclusion:
If moving forward on this topic (in case WLTP is requesting a test procedure) IWG EVE will provide test procedure for representative aging to WLTP
OICA stated that the battery durability topic and its effect on the vehicle durability is topic which is regulated by the market and the customer expectations and that there is no need to already define a specific aging procedure
procedures would be defined on the already available knowledge but – as mentioned earlier – we are just at the beginning of understanding battery chemistry
procedure would be based on already available technologies on the market à could ban the development of promising technologies out of the market
Battery performance and durability is a very complex topic and that it may not be feasible to include an artificial methodology of battery aging into phase 2b.
OICA and JP stated that a regulation of battery durability is premature at this time; USA has no official preference
Recommendation
Recommendation from IWG EVE to GRPE is that regulation of battery durability is premature at this time but the topic should be revisited in the future. In the meantime the group suggests passive observation of this topic
