Agenda Item 3.
OIL #55: Phase-specific CO2 calculation

ACEA presents the results concerning out a calculation of phase specific range values for PEV. If such values are available, there is no need for WLTCcity anymore. Comparison between simulation and calculation shows small deviation for both a vehicle that can follow the cycle and for a vehicle that cannot follow the cycle.

Japan can accept the procedure, but will need to investigate how effect shorten test procedure.

EC is of the opinion that there is a need for more validation from testing.

Japan has test data that can be shown until WLTP IWG #9.

Sub group EV agrees on the principal of calculation of phase specific values.

The need for phase specific values is a discussion on political level between EC and Japan. EC does not need phase specific values, but accepts that Japan request them.

Conclusion:
ACEA demonstrates that phase specific range calculation for PEV works well. For HEVs, phase specific value could be obtained by the new proposal from ACEA, as mentioned in open issue #50 this meeting. Then, this issue could be closed in #9 meeting as well, after the JPN’s response for the proposal.
