              2.2. Vehicle on-board REESS current data

              As an alternative to paragraph 2.1. of this appendix, the manufacturer may use on-board REESS current measurement data. The accuracy of these data shall be demonstrated to the responsible authority.

              3.1. External REESS voltage measurement

              During the tests described in paragraph 3. of this annex, the REESS voltage shall be measured with the equipment and accuracy requirements specified in paragraph 1.1. of this annex. To measure the REESS voltage using external measuring equipment, the manufacturers shall support the responsible authority by providing REESS voltage measurement points and safety instructions.

              3.2. Nominal REESS voltage

              For NOVC-HEVs, NOVC-FCHVs, OVC-HEVs and OVC-FCHVs, instead of using the measured REESS voltage according to paragraph 3.1. of this appendix, the nominal voltage of the REESS determined according to IEC 60050-482 may be used.

              3.3. Vehicle on-board REESS voltage data

              As an alternative to paragraphs 3.1. and 3.2. of this appendix, the manufacturer may use the on-board voltage measurement data. The accuracy of these data shall be demonstrated to the responsible authority.

Preconditioning, soaking and REESS charging conditions of PEVs, OVC-HEVs and OVC-FCHVs (as applicable)
              1. This appendix describes the test procedure for REESS and combustion engine preconditioning in preparation for:
                  (a) Electric range, charge-depleting and charge-sustaining measurements when testing OVC-HEVs and OVC-FCHVs; and
                  (b) Electric range measurements as well as electric energy consumption measurements when testing PEVs.
              2. OVC-HEV and OVC-FCHV preconditioning and soaking
              2.1. Preconditioning and soaking when the test procedure starts with a charge-sustaining test
              2.1.1. For preconditioning the combustion engine, the vehicle shall be driven over at least one applicable WLTP test cycle. During each driven preconditioning cycle, the charging balance of the REESS shall be determined. The preconditioning shall be stopped at the end of the applicable WLTP test cycle during which the break-off criterion is fulfilled according to paragraph 3.2.4.5. of this annex.
              2.1.2. As an alternative to paragraph 2.1.1. of this appendix, at the request of the manufacturer and upon approval of the responsible authority, the state of charge of the REESS for the charge-sustaining Type 1 test may be
