1.1.1. The correction shall be applied on the phase-specific fuel consumptions for NOVC-FCHVs and OVC-FCHVs of the charge-sustaining Type 1 test, and on the phase-specific CO2 emissions for NOVC-HEVs and OVC-HEVs of the charge-sustaining Type 1 test.

              1.1.2. The application of the correction over the total cycle on the fuel consumption for NOVC-FCHVs and OVC-FCHVs, on the CO2 emission for NOVC-HEVs and OVC-HEVs is based on the charge-sustaining REESS energy change  of the charge-sustaining Type 1 test and the correction criterion c.

              For the calculation of , paragraph 4.3. of this annex shall be used. The considered period j used in paragraph 4.3. of this annex is defined by the charge-sustaining Type 1 test. The correction criterion c shall be determined according to paragraph 1.2. of this Appendix.

              1.1.3. The correction over the total cycle shall be applied on the fuel consumption for NOVC-FCHVs and OVC-FCHVs, the CO2 emission for NOVC-HEVs and OVC-HEVs if  is negative which corresponds to REESS discharging and the correction criterion c calculated in paragraph 1.2. of this appendix is greater than the applicable threshold according to Table A8.App2/1.

              1.1.4. The correction over the total cycle may be omitted on the fuel consumption for NOVC-FCHVs and OVC-FCHVs, the CO2 emission for NOVC-HEVs and OVC-HEVs and uncorrected values may be used if:

                  (a)  is positive which corresponds to REESS charging and the correction criterion c calculated in paragraph 1.2. of this appendix is greater than the applicable threshold according to Table A8.App2/1;
                  (b) The correction criterion c calculated in paragraph 1.2. of this appendix is smaller than the applicable threshold according to Table A8.App2/1;
                  (c) The manufacturer can prove to the responsible authority by measurement that there is no relation between  and charge-sustaining CO2 emission and  and fuel consumption respectively.
              1.2.  The correction criterion c is the ratio between the absolute value of the REESS electric energy change and the fuel energy and shall be calculated as follows:
              where:
                      is the charge-sustaining REESS energy change according to paragraph 1.1.2. of this appendix, Wh;
                      is the charge-sustaining energy content of the consumed fuel according to paragraph 1.2.1. of this appendix in the case of NOVC-HEVs and OVC-HEVs, and according to paragraph 1.2.2. of this appendix in the case of NOVC-FCHVs and OVC-FCHVs, Wh.
              1.2.1. Charge-sustaining fuel energy for NOVC-HEVs and OVC-HEVs
              The charge-sustaining energy content of the consumed fuel for NOVC-HEVs and OVC-HEVs shall be calculated using the following equation:
                     where:
                      is the charge-sustaining energy content of the consumed fuel of the applicable WLTP test cycle of the charge-sustaining Type 1 test, Wh;
                      is the heating value according to Table A6.App2/1, kWh/l;
                      is the non-balanced charge-sustaining fuel consumption of the charge-sustaining Type 1 test, not corrected for the
