WLTP-DHC 17 -xx 1. ICE / NOVC-HEV / CS test for OVC-HEV Calculation process Combined data (L ~ Ex-H) RCB factor@RCB(L~Ex-H) (only CO 2) Combined data (L ~ H) RCB factor@RCB(L~H) (only CO 2) Ki (L ~ H for PM, H for others or Ex-H for all) Ki (L ~ H) All except PM Sample (L ~ H) Sample (PM) Required measureme nt items per each test RCB Calculation process Sample (all except PM) LOW 589 s MIDDLE 433 s HIGH 455 s Ex-HIGH* 323 s RCB(L) Sample(L) RCB(M) Sample(M) RCB(H) Sample(H) RCB(Ex-H) Sample(Ex-H) Ki (L) Ki (M) Ki (H) (only CO 2) RCB factor@RCB(L) RCB factor@RCB(M) RCB factor@RCB(H) Ki (H or Ex-H) (only CO 2) RCB factor@RCB(Ex-H) L phase data M phase H phase Ex-H phase data Each phase information (note : no PM data is available) Note ) Ex-HIGH phase is exempted as per CPs need Fuel consumption is derived after carbon related pollutants were compensated. 2

WLTP-DHC 17 -xx 2. CD test for OVC-HEV and BEV unit Repeat phase units Measurement items unit OVC-HEV Pollutants RCB L+M CO 2 per unit L+M+H (for CPs not require Ex-H) PM per unit, L + M + H + Ex-H (for CPs require Ex-H) Others and RCB per phase unit BEV AER Driving distance until first start of ICE Range Driving distance until reach break-off criteria and each phase consumed battery energy Consider to apply shorten test procedure for BEV range in later stage. Calculate each phase values during CD (pollutants, CO 2, FC, EAER, Rcda and so on 3
