Presentation of ACEA document:
Simulation results show that it is possible that WLTC complete cycle can be replaced by the shorten test procedure. Since this methodology can calculate phase specific values it
would also be possible to skip WLTCcity . This would lead in consequence to a reduced test burden.
EC is of the opinion that the accuracy of the shorten test procedure needs to be demonstrated. Japan can provide data for this on the next meeting. EC means that since HEV provide WLTCcity values PEV also needs to do that in order to stay consistent.
But if the procedure does not require measuring WLTCcity on HEV, this means that it is relevant to calculate WLTCcity also for HEV. If this can be done with good accuracy.
ACEA supports shorten test procedure, but some issues still need to be worked on (final ACEA conclusion slide).
Presentation from Japan regarding shorten test procedure:
Japan supports to introduce shorten test procedure as baseline for PEV because of its features.
Next step is more validation of the procedure.
