1. Proposal for optional procedure of All Electric Range test (BEV)
WLTP-DTP-E-labproc-072
Proposal from JAPAN

2. All electric range test for BEV
It is necessary to conduct each phase range (Low, Middle, High and ex-high) test separately due to more precise information for customer and in line with conventional vehicle sampling strategy.
However, this sequence is testing burden for laboratories.
SAE has been working on to establish the effective test procedure.
Japan propose to have a study whether this shorten procedure can also be applied for WLTC.

4. The proposal of shorten test for WLTC (Proposal 1)
1) To have equivalent driving distance for each phase, # of L and M phase driving cycle are double of H and Ex-H driving.
2) During later stage of test sequence, lower driving energy cycle (i.e. L and M) is appropriate to secure cycle traceability.

2) To have equivalent driving distance for each phase, # of L and M phase driving cycle are double of H driving.
