The WLTP E-Lab subgroup decided to change its name as part of the shift in focus from the initial WLTP GTR to the new “phase 1b” and future phases in the development of the regulation. Consequently, this session can be considered as the 6th session of the E-Lab group and/or as the 4th session of the Electric Vehicles subgroup.
The original JP proposal is only applicable to vehicles with at least one complete CD cycle. ACEA asked about the case of vehicles with only the transition cycle. There is no appropriate solution for this case at the moment.
With this method there should be a correction of RCB for each phase in the CS test even when no correction is necessary for whole cycle, this is currently not in the GTR. JP accepts that this method gives values with low accuracy. Nevertheless, JP persists in a position to provide a large number of values, such as FC, in order for vehicle users to compare their driving behavior. ACEA questioned the necessity of such large number of FC values.
JP means that this is a calculation approach and no need for a validation. But there might be of interest to test different types of OVC-HEV to see how the proposed calculation method works. For example vehicles with only a transition cycle in the CD test. JP will take the response back to the JP EV group for further discussion and present the conclusion on a coming meeting.
