4.2.4. Test procedure

4.2.4.1.

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

4.2.4.2.

The test procedures defined in either point 4.2.4.2.1. or 4.2.4.2.2. may be used.

4.2.4.2.1.

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 applicable type I driving cycle (end of sampling (ES)).

4.2.4.2.2.

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 applicable type I driving cycle during which the battery reached the minimum state of charge in accordance with the following procedure (end of sampling (ES)):

4.2.4.2.2.1.

the electricity balance Q (Ah) is measured over each combined cycle, using the procedure in Appendix 3.2., and used to determine when the battery’s minimum state of charge has been reached.

4.2.4.2.2.2.

the battery’s 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 percent 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 points 4.2.4.5. and 4.4., provided that the electricity balance for each additional test cycle shows less discharge of the battery than over the previous cycle.

4.2.4.2.2.3.

between each pair of cycles, a hot soak period of up to ten minutes is allowed. The powertrain shall be switched off during this period.

4.2.4.3.

The vehicle shall be driven using the applicable driving cycle and gear-shifting prescriptions as defined in appendix 9 to Annex II.

4.2.4.4.

The exhaust gases shall be analysed according to Annex II in force at the time of approval of the vehicle.

4.2.4.5.

The CO₂ emission and fuel consumption results on the test cycle for Condition A shall be recorded (m₁ (g) and c₁ (l) respectively). In the case of testing in accordance with point 4.2.4.2.1., m₁ and c₁ are the results of the single combined cycle run. In the case of testing in accordance with point 4.2.4.2.2., m₁ and c₁ are the sums of the results of the N combined cycles run:
