Annex B8

Pure electric, hybrid electric and compressed hydrogen fuel cell hybrid vehicles
              1. General requirements
              In the case of testing NOVC-HEVs, OVC-HEVs and NOVC-FCHVs and OVC-FCHVs (as applicable), Appendix 2 and Appendix 3 to this annex shall replace Appendix 2 to Annex B6.
              Unless stated otherwise, all requirements in this annex shall apply to vehicles with and without driver-selectable modes. Unless explicitly stated otherwise in this annex, all of the requirements and procedures specified in Annex B6 and Annex B7 shall continue to apply for NOVC-HEVs, OVC-HEVs, NOVC-FCHVs, OVC-FCHVs and PEVs (as applicable).
              1.1. Units, accuracy and resolution of electric parameters
              Units, accuracy and resolution of measurements shall be as shown in Table A8/1.

              1.2. Emission and fuel consumption testing
              Parameters, units and accuracy of measurements shall be the same as those required for pure ICE vehicles.
              1.3. Rounding of test results
              1.3.1. Unless intermediate rounding is required, intermediate steps in the calculations shall not be rounded.
              1.3.2. In the case of OVC-HEVs and NOVC-HEVs, the final criteria emission results shall be rounded according to paragraph 1.3.2. of Annex B7, the NOx correction factor KH shall be rounded according to paragraph 1.3.3. of Annex B7, and the dilution factor DF shall be rounded according to paragraph 1.3.4. of Annex B7.
              1.3.3. For information not related to standards, good engineering judgement shall be used.
              1.3.4. Rounding of range, CO2, energy consumption and fuel consumption results is described in the calculation tables of this annex.

              1.4. Vehicle classification

              All OVC-HEVs, NOVC-HEVs, PEVs, OVC-FCHVs and NOVC-FCHVs shall be classified as Class 3 vehicles. The applicable test cycle for the Type 1 test procedure shall be determined according to paragraph 1.4.2. of this annex based on the corresponding reference test cycle as described in paragraph 1.4.1. of this annex.
              1.4.1. Reference test cycle
              1.4.1.1. The Class 3 reference test cycles are specified in paragraph 3.3. of Annex B1.
              1.4.1.2. For PEVs, the downscaling procedure, according to paragraphs 8.2.3. and 8.3. of Annex B1, may be applied on the test cycles according to
