only be applied if there is no engine start in the first cycle of the charge-depleting Type 1 test during Type Approval. In the case there is an engine start, this paragraph shall be omitted.

              2.1.  The following value shall be determined and used as a reference value for verifying the conformity of production:

              In the case that the interpolation method is applied,

              In the case that the interpolation method is not applied,

                     where:

                           is the reference charge-depleting electric energy consumption of an individual vehicle for the conformity of production, Wh/km;

                           is the charge-depleting electric energy consumption of vehicle L determined according to paragraph 2.2. of this appendix, Wh/km;

                           is the charge-depleting electric energy consumption of vehicle H determined according to paragraph 2.2. of this appendix, Wh/km;

                           is the charge-depleting electric energy consumption of vehicle i determined according to paragraph 2.2. of this appendix, Wh/km;

                          is the interpolation coefficient for the considered individual vehicle for the applicable WLTP test cycle, according to paragraph 4.5.3. of this annex.
              2.2. Calculation of the   and

              where:

                         i represents – in the case the interpolation method is applied – the index L for vehicle L and the index H for vehicle H. In the case the interpolation method is not applied, index i represents the vehicle tested.

                          is the aligned charge-depleting electric energy consumption based on the REESS depletion of the first applicable WLTC test cycle, Wh/km;

                           is average of the measured charge-depleting electric energy consumption of vehicle i based on the REESS depletion of the first applicable WLTC test cycle according to paragraph 4.3. of this annex, Wh/km;

                          is the alignment factor of vehicle i

                     where

                     For Level 1A

                            where

                             is the declared charge-depleting electric energy consumption of vehicle i according to Table A8/8 Step no. 14, Wh/km;

                             is the average of the measured charge-depleting electric energy consumption of vehicle i according to Table A8/8 Step no. 13, Wh/km;

                            For Level 1B

                            where

                             is the declared electric energy consumption of vehicle i of the charge-depleting Type 1 test according to Table A8/9 Step no. 8, Wh/km;

                             is the average of the measured electric energy consumption of vehicle i of the charge-depleting Type 1 test according to Table A8/9 Step no. 8.

Annex B9

Determination of method equivalency
              This annex is only applicable for Level 1A;

              1. General requirement

               Upon request of the manufacturer, other measurement methods may be approved by the responsible authority if they yield equivalent results in accordance with paragraph 1.1. of this annex. The equivalence of the candidate method shall be demonstrated to the responsible authority.

              1.1. Decision on equivalency

              A candidate method shall be considered equivalent if the accuracy and precision is equal to or better than the reference
