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.

Consider to apply shorten test procedure for BEV
range in later stage.
Calculate each phase values during CD (pollutants, CO2, FC, EAER, Rcda and so on
