p, km;

                      is the equivalent all-electric range for vehicle H for the considered period p, km;

                      is the interpolation coefficient for the considered individual vehicle for period p;

                      is the index of the individual period within the applicable test cycle.

              For Level 1A;
              The considered periods shall be the low phase, medium phase, high phase, extra high phase, the applicable WLTP city test cycle and the applicable WLTP test cycle.

              For Level 1B;
              The considered periods shall be the applicable WLTP test cycle.

              4.5.8. Adjustment of values

              The individual EAER value determined in accordance with paragraph 4.5.7.3. of this annex may be decreased by the manufacturer. In such cases:

              The EAER phase values shall be decreased by the ratio of the decreased EAER value divided by the calculated EAER value. This shall not compensate for technical elements that would effectively require a vehicle to be excluded from the interpolation family.

              4.6. Stepwise procedure for calculating the final test results of OVC-HEVs

              In addition to the stepwise procedure for calculating the final charge-sustaining test results for gaseous emission compounds according to paragraph 4.1.1.1. of this annex and for fuel consumption and fuel efficiency according to paragraph 4.2.1.1. of this annex, paragraphs 4.6.1. and 4.6.2. of this annex describe the stepwise calculation of the final charge-depleting as well as the final charge-sustaining and charge-depleting weighted test results.

              4.6.1. Stepwise procedure for calculating the final test results of the charge-depleting Type 1 test for OVC-HEVs

              The results shall be calculated in the order described in Table A8/8. All applicable results in the column "Output" shall be recorded. The column "Process" describes the paragraphs to be used for calculation or contains additional calculations.

              For the purpose of this table, the following nomenclature within the equations and results is used:

                  c complete applicable test cycle;

                  p every applicable cycle phase; for the purpose of EAERcity calculation (as applicable), p shall represent the city driving cycle;

                  i applicable criteria emission component;

                  CS charge-sustaining;

              CO2 CO2 emission.
