that, during the test, a special charge procedure has not occurred.
              2.2.3.2. End-of-charge criterion
              The end-of-charge criterion is reached when the on-board or external instruments indicate that the REESS is fully charged. If the charging is performed during soaking and finished before the minimum required soaking time as defined in paragraph 2.7. of Annex B6, the vehicle shall stay connected to the grid at least until the minimum required soaking time is reached.
              3. PEV preconditioning and soaking
              3.1. Initial charging of the REESS
              Initial charging of the REESS consists of discharging the REESS and applying a normal charge.
              3.1.1. Discharging the REESS
              The discharge procedure shall be performed according to the manufacturer's recommendation. The manufacturer shall guarantee that the REESS is as fully depleted as is possible by the discharge procedure.
              3.1.2. Soaking and application of a normal charge
              Soaking of the vehicle shall be performed in accordance with paragraph 2.7. of Annex B6.
              During soak, the REESS shall be charged using the normal charging procedure as defined in paragraph 2.2.3. of this appendix.

Utility factors (UF) for OVC-HEVs and OVC-FCHVs (as applicable)
              1. Each Contracting Party may develop its own UFs.
              2. The methodology recommended for the determination of a UF curve based on driving statistics is described in SAE J2841 (Sept. 2010, Issued 2009-03, Revised 2010-09).
              3. For the calculation of a fractional utility factor UFj for the weighting of period j, the following equation shall be applied by using the coefficients from Table A8.App5/1.

              where:

                   UFj utility factor for period j;

                   dj measured distance driven at the end of period j, km;

                   Ci ith coefficient (see Table A8.App5/1);

                   dn normalized distance (see Table A8.App5/1), km;

                   k number of terms and coefficients in the exponent;

                   j number of period considered;

                   i number of considered term/coefficient;

                    sum of calculated utility factors up to period (j-1).

Selection of driver-selectable modes
              1. General requirement

              1.1. The manufacturer shall select the driver-selectable mode for the Type 1 test procedure according to paragraphs 2. to 4. inclusive of this appendix which enables the vehicle to follow the considered test cycle within the speed trace tolerances according to paragraph 2.6.8.3.1.2. of Annex B6. This shall apply to all vehicle systems with driver-selectable modes including those not solely specific to the transmission.

              1.2. The manufacturer shall provide evidence to the responsible authority concerning:

                  (a) The availability of a predominant mode under the considered conditions;

              (b) The maximum
