a normal overnight charge

          The electrical energy/power storage device shall be charged according to the following procedure.

         3.2.2.5.1. Normal overnight charge procedure

          The charging is carried out:

            (a) With the on board charger if fitted; or

            (b) With an external charger recommended by the manufacturer using the charging pattern prescribed for normal charging;

            (c) In an ambient temperature comprised between 20 °C and 30 °C. This procedure excludes all types of special charges that could be automatically or manually initiated like, for instance, the equalisation charges or the servicing charges. The manufacturer shall declare that during the test, a special charge procedure has not occurred.

         3.2.2.5.2. End of charge criteria

          The end of charge criteria corresponds to a charging time of twelve hours, except if a clear indication is given to the driver by the standard instrumentation that the electrical energy/power storage device is not yet fully charged.

          In this case,

         3.2.3. Test procedure

         3.2.3.1. The vehicle shall be started up by the means provided for normal use to the driver. The first cycle starts on the initiation of the vehicle start-up procedure.

         3.2.3.2. The test procedures defined in either paragraph 3.2.3.2.1. or 3.2.3.2.2. may be used.

         3.2.3.2.1. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and end on conclusion of the final idling period in the extra-urban cycle (Part Two, end of sampling (ES)).

         3.2.3.2.2. Sampling shall begin (BS) before or at the initiation of the vehicle start up procedure and continue over a number of repeat test cycles. It shall end on conclusion of the final idling period in the first extra-urban (Part Two) cycle during which the battery reached the minimum state of charge according to the criterion defined below (end of sampling (ES)).

          The electricity balance Q [Ah] is measured over each combined cycle, using the procedure specified in Appendix 2 to this annex, and used to determine when the battery minimum state of charge has been reached.

          The battery minimum state of charge is considered to have been reached in combined cycle N if the electricity balance measured during combined cycle N+1 is not more than a 3 per cent discharge, expressed as a percentage of the nominal capacity of the battery (in Ah) in its maximum state of charge, as declared by the manufacturer. At the manufacturer's request additional test cycles may be run and their results included in the calculations in paragraphs 3.2.3.5. and 3.4.1. provided that the electricity balance for each additional test cycle shows less discharge of the battery than over the previous cycle.

          In between each of the cycles a hot soak period of up to ten minutes is allowed. The powertrain shall
