Commission Delegated Regulation (EU) No 134/2014Show full title

3.1.2. Condition A

3.1.2.1. The procedure shall start with the discharge of the electrical energy/power storage device of the vehicle while driving (on the test track, on a chassis dynamometer, etc.) in any of the following conditions:

(a)

at a steady speed of 50 km/h until the fuel-consuming engine starts up;

(b)

if a vehicle cannot reach a steady speed of 50 km/h without the fuel-consuming engine starting up, the speed shall be reduced until it can run at a lower steady speed at which the fuel-consuming engine does not start up for a defined time or distance (to be determined by the technical service and the manufacturer subject to the agreement of the approval authority);

(c)

in accordance with the manufacturer’s recommendation.

The fuel-consuming engine shall be stopped within ten seconds of being automatically started.

3.1.2.2. Conditioning of vehicle

The vehicle shall be conditioned by driving the applicable type I driving cycle as set out in Appendix 6.

3.1.2.3. After this preconditioning and before testing, the vehicle shall be kept in a room in which the temperature remains relatively constant between 293,2 K and 303,2 K (20 °C and 30 °C). This conditioning shall be carried out for at least six hours and continue until the temperature of the engine oil and coolant, if any, are within ± 2 K of the temperature of the room, and the electrical energy/power storage device is fully charged as a result of the charging prescribed in point 3.1.2.4.

3.1.2.4. During soak, the electrical energy/power storage device shall be charged with any of the following:

(a)

the on-board charger if fitted;

(b)

an external charger recommended by the manufacturer and referred to in the user manual, using the normal overnight charging procedure set out in point 3.2.2.4. of Appendix 3 to Annex VII.

This procedure excludes all types of special charges that could be automatically or manually initiated, e.g. equalisation or servicing charges.

The manufacturer shall declare that a special charge procedure has not occurred during the test;

End-of-charge criterion.

The end-of-charge criterion corresponds to a charging time of 12 hours, except where the standard instrumentation gives the driver a clear indication that the electrical energy storage device is not yet fully charged.

In this case, the maximum time is = 3 times the claimed battery capacity (Wh) / mains power supply (W).

3.1.2.5. Test procedure

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

3.1.2.5.2. The test procedures described in points 3.1.2.5.2.1. or 3.1.2.5.2.2. shall be used in accordance with the type I test procedure set out in Appendix 6.

3.1.2.5.2.1. Sampling shall begin (BS) before or at the initiation of the vehicle start-up procedure and end on conclusion of the final idling period of the applicable type I test cycle (end of sampling (ES)).

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

3.1.2.5.2.2.1.

the electricity balance Q (Ah) is measured over each combined cycle according to the procedure in Appendix 3.2. to Annex VII and used to determine when the battery minimum state of charge has been reached;

3.1.2.5.2.2.2.

the battery minimum state of charge is considered to have been reached in combined cycle N if the electricity balance Q 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 3.1.2.5.5. and 3.1.4.2, provided that the electricity balance Q for each additional test cycle shows less discharge of the battery than over the previous cycle;

3.1.2.5.2.2.3.

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

3.1.2.5.3. The vehicle shall be driven according to the provisions in Appendix 6.

3.1.2.5.4. The exhaust gases shall be analysed according to the provisions in Annex II.

3.1.2.5.5. The test results shall be compared with the limits set out in Annex VI to Regulation (EU) No 168/2013 and the average emission of each pollutant (expressed in mg per kilometre) for Condition A shall be calculated (M_1i).

In the case of testing according to point 3.1.2.5.2.1., (M_1i) is the result of the single combined cycle run.

In the case of testing according to point 3.1.2.5.2.2., the test result of each combined cycle run (M_1ia), multiplied by the appropriate deterioration factor and K_i factors, shall be less than the limits in Part A of Annex VI to Regulation (EU) No 168/2013. For the purposes of the calculation in point 3.1.4., M_1i shall be defined as:
