COMMISSION REGULATION (EU) 2022/1379

of 5 July 2022

amending Regulation (EU) 2017/2400 as regards the determination of the CO2 emissions and fuel consumption of medium and heavy lorries and heavy buses and to introduce electric vehicles and other new technologies

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information (1), and in particular Article 4(3) and Article 5(4), point (e), thereof,

Whereas:

(1)

Commission Regulation (EU) 2017/2400 (2) introduces a common method to objectively compare the performance of heavy-duty vehicles placed on the Union market as regards their CO2 emissions and fuel consumption. It lays down provisions for the certification of components with an impact on CO2 emissions and fuel consumption of heavy-duty vehicles, introduces a simulation tool for the purpose of determining and declaring CO2 emissions and fuel consumption of those vehicles, and lays down, inter alia, requirements for Member States’ authorities and manufacturers to verify the conformity of the certification of the components and the conformity of the simulation tool operation.

(2)

Regulation (EU) 2018/858 of the European Parliament and of the Council (3) has moved the rules on access to vehicle on-board diagnostic information and vehicle repair and maintenance information from Regulation (EC) No 595/2009. In order to align the wording of Regulation (EU) 2017/2400 to the changed wording of Regulation (EC) No 595/2009, the references to on-board diagnostic information and vehicle repair and maintenance information need to be removed from Regulation (EU) 2017/2400.

(3)

Regulation (EU) 2017/2400 determines CO2 emissions and fuel consumption of heavy lorries. However, in order to provide a better view on CO2 emissions, CO2 emissions of more vehicles need to be calculated. It is therefore necessary to determine CO2 emissions and fuel consumption of other heavy duty vehicles, namely medium lorries and heavy buses.

(4)	To appropriately cover future technologies, it is necessary to specify additional requirements for new technologies such as hybrid and pure electric vehicles, dual-fuel vehicles, waste heat recovery and advanced driver assistance systems.

(5)

As the on-road verification testing procedure has proved to be an important tool for the verification of calculations of CO2 emissions and fuel consumption, it is appropriate for it to apply for medium lorries and new technologies. However, due to the complexities of the multi-stage production and approval system that applies for heavy buses, it is not possible at this moment to have the on-road verification testing procedure extended to them.

(6)	Some definitions and requirements in Regulation (EU) 2017/2400 need further clarification and corrections, including further alignment to the CO2 emission performance standards for new heavy-duty vehicles laid down in Regulation (EU) 2019/1242 of the European Parliament and of the Council (4).

(7)	In order to provide Member States, national authorities and economic operators with sufficient time to prepare for the application of the rules introduced by this Regulation, the date of application of this Regulation should be deferred.

(8)

As certain manufacturers may prefer to meet the requirements set out in this Regulation before its date of application, they should have the possibility to obtain a licence to operate the simulation tool and receive a certification for components in accordance with the rules introduced by this Regulation before its date of application.

(9)

For certain groups of vehicles and certain technologies the simulation tool required for the obligation to determine and declare CO2 emissions and fuel consumption of new vehicles, will only be available after the general application date of this Regulation. In these cases the requirements can only be required from the moment of availability of the simulation tool. This is why some provisions of this Regulation shall only apply from a later date.

(10)	The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,

HAS ADOPTED THIS REGULATION:

2. Method to determine CO2 emissions and fuel consumption for heavy buses

2.1.

For heavy buses the vehicle specifications of the complete vehicle or completed vehicle including properties of the final bodywork and auxiliary units shall be reflected in the results for CO2 emissions and fuel consumption. In the case of heavy buses built in steps, more than a single manufacturer may be involved in the process of generation of input data and input information and the operation of the simulation tool. For heavy buses the CO2 emissions and fuel consumption shall be based on the following two different simulations:

(a)	for the primary vehicle;

(b)	for the complete vehicle or completed vehicle.

2.2.

If a heavy bus is approved by a manufacturer as a complete vehicle, the simulations shall be performed for both the primary vehicle and the complete vehicle.

2.3.

For the primary vehicle the input to the simulation tool covers input data regarding the engine, transmission, tyres and input information for a subset of auxiliary units (6). The classification into vehicle groups is performed in accordance with Table 3 based on the number of axles and the information whether the vehicle is an articulated bus or not. In the simulations for the primary vehicle the simulation tool allocates a set of four different generic bodies (high floor and low floor, single deck and double deck bodywork) and simulates the 11 mission profiles as listed in Table 3 for each vehicle group for two different loading conditions. This leads to a set of 22 results for CO2 emissions and fuel consumption for a primary heavy bus. The simulation tool produces the vehicle information file for the initial step (VIF1), which contains all necessary data to be handed over to the subsequent manufacturing step. The VIF1 comprises all non-confidential input data, the results for energy consumption (7) in [MJ/km], information on the primary manufacturer and the relevant hashes (8).

2.4.

The manufacturer of the primary vehicle shall make the VIF1 available to the manufacturer responsible for the subsequent manufacturing step. Where a manufacturer of a primary vehicle provides data going beyond the primary vehicle requirements as set out in Annex III, this data does not influence the simulation results for the primary vehicle but is written into the VIF1 to be considered in later steps. For a primary vehicle the simulation tool furthermore produces a manufacturer’s records file.

2.5.

In the case of an interim vehicle, the interim manufacturer is responsible for a sub-set of relevant input data and input information for the final bodywork (9). An interim manufacturer does not apply for certification of the completed vehicle. An interim manufacturer shall add or update information relevant for the completed vehicle and operate the simulation tool to produce an updated and hashed version of the vehicle information file (VIFi) (10). The VIFi shall be made available to the manufacturer responsible for the subsequent manufacturing step. For interim vehicles the VIFi also covers the task of documentation towards approval authorities. No simulations of CO2 emissions and/or fuel consumption are performed on interim vehicles.

2.6.

If a manufacturer performs modifications to an interim, complete or completed vehicle, which would require updates to the input data or the input information allocated to the primary vehicle (e.g. a change of an axle or of tyres), the manufacturer performing the modification acts as a primary vehicle manufacturer with the corresponding responsibilities.

2.7.

For a complete or completed vehicle the manufacturer shall complement and, if necessary, update the input data and input information for the final bodywork as transmitted in the VIFi from the previous manufacturing step and shall operate the simulation tool to calculate the CO2 emissions and fuel consumption. For the simulations at this stage, heavy buses are classified based on the six criteria set out in point 1.2.3 into the vehicle groups as listed in Tables 4, 5 and 6. To determine CO2 emissions and fuel consumption of complete vehicles or completed vehicles that are heavy buses the simulation tool performs the following calculation steps:

2.7.1.

Step 1 - Selection of the primary vehicle sub-group which matches the bodywork of the complete or completed vehicle (e.g. ‘P34 DD’ for ‘34f’) and making available the corresponding results for energy consumption from the primary vehicle simulation.

2.7.2.

Step 2 - Performing simulations to quantify the influence of the bodywork and auxiliaries of the complete vehicle or completed vehicle compared to the generic bodywork and auxiliaries, as considered in the simulations for the primary vehicle regarding energy consumption. In these simulations, generic data are used for the set of primary vehicle data, which are not part of the information transfer between different manufacturing steps as provided by the VIF (11).

2.7.3.

Step 3 - Combining energy consumption results from the primary vehicle simulation as made available by step 1 with the results from step 2 provides the energy consumption results of the complete or completed vehicle. The details of this calculation step are documented in the user manual of the simulation tool.

2.7.4.

Step 4 - Results for CO2 emissions and fuel consumption of the vehicle are calculated based on the results of step 3 and the generic fuel specifications as stored in the simulation tool. Steps 2, 3 and 4 are performed separately for each combination of mission profile as listed in the Tables 4, 5 and 6 for the vehicle groups in both low and representative loading condition.

2.7.5.

For a complete vehicle or completed vehicle the simulation tool produces a manufacturer’s records file, a customer information file as well as a VIFi. The VIFi shall be made available to the subsequent manufacturer in the event the vehicle undergoes a further step to be completed.

Figure 2 shows the data flow based on the example of a vehicle produced in five CO2 related manufacturing steps.

The liquid containing systems are filled to 100 % of the capacity specified by the manufacturer, except the liquid containing systems for waste water that must remain empty.

For medium rigid lorries, heavy rigid lorries and tractors the mass is determined without superstructure and corrected by the additional weight of the non-installed standard equipment as specified in point 4.3. The mass of a standard body, standard semi-trailer or standard trailer to simulate the complete vehicle or complete vehicle-(semi-)trailer combination are added automatically by the simulation tool. All parts that are mounted on and above the main frame are regarded as superstructure parts if they are installed only for facilitating a superstructure, independent of the necessary parts for in running order conditions.

For heavy buses that are primary vehicles “corrected actual mass of the vehicle” is not applicable as the generic mass value is allocated by the simulation tool.

h1 is the difference between point A, but determined in the cross section of the vehicle at the rear end of first passenger door, and point B

h2 is the difference between point A and point B

Special case 2, inclined: Height of the integrated body is the average of h1 and h2, where

h1 is the difference between point A, but determined in the cross section of the vehicle at the rear end of first passenger door, and point B

h2 is the difference between point A and point B

Special case 3, open top with roof section:

Height of the integrated body determined in the remaining roof section

Special case 4, open top without any roof section:

Height of the integrated body is the difference between the highest point of the vehicle within one meter in the longitudinal direction of the front screen or upper front screen, in the case of a double decker, and point B

For all other cases not covered by standard or special cases 1 to 4, the height of the integrated body is the difference between the highest point of the vehicle and point B. This parameter is relevant only for heavy buses.

7. Vehicle specific engine idling speed

7.1.

The engine idling speed has to be declared for each individual vehicle with an ICE. This declared vehicle engine idling shall be equal or higher than specified in the engine input data approval.

8. Advanced driver assistance systems

8.1

The following types of advanced driver assistance systems, which are primarily aiming for reduction of fuel consumption and CO2 emissions, shall be declared in the input to the simulation tool:

8.1.1

Engine stop-start during vehicle stops: system which automatically shuts down and restarts the internal combustion engine during vehicle stops to reduce engine idling time. For automatic engine shut down the maximum time delay after the vehicle stop shall be not longer than 3 seconds.

8.1.2

Eco-roll without engine stop-start: system which automatically decouples the internal combustion engine from the drivetrain during specific downhill driving conditions with low negative gradients. The system shall be active at least at all cruise control set speeds above 60 km/h. Any system to be declared in the input information to the simulation tool shall cover either one or both of the following functionalities:

Functionality (1)’

The combustion engine is de-coupled from the drivetrain, and engine operates at idle speed. In the case of APT-transmissions, the torque converter lock-up clutch is closed.

Functionality (2) Torque converter lock-up clutch open

The torque converter lock-up clutch is open during Eco-roll mode. This allows the engine to operate in coast mode at lower engine speeds and reduces or even eliminates fuel injection. Functionality (2) is relevant only for APT-transmissions.

8.1.3

Eco-roll with engine stop-start: system which automatically decouples the internal combustion engine from the drivetrain during specific downhill driving conditions with low negative slopes. During these phases the internal combustion engine is shut down after a short time delay and keeps shut down during the main share of the eco-roll phase. The system shall be active at least at all cruise control set speeds of above 60 km/h.

8.1.4

Predictive cruise control (PCC): systems which optimise the usage of potential energy during a driving cycle based on an available preview of road gradient data and the use of a GPS system. A PCC system declared in the input to the simulation tool shall have a gradient preview distance longer than 1 000 meters and cover all following functionalities:

(1)	Crest coasting Approaching a crest the vehicle velocity is reduced before the point where the vehicle starts accelerating by gravity alone compared to the set speed of the cruise control so that the braking during the following downhill phase can be reduced.

(2)	Acceleration without engine power During downhill driving with a low vehicle velocity and a high negative slope the vehicle acceleration is performed without any engine power usage so that the downhill braking can be reduced.

(3)	Dip coasting During downhill driving when the vehicle is braking at the overspeed velocity, PCC increases the overspeed for a short period of time to end the downhill event with a higher vehicle velocity. Overspeed is a higher vehicle speed than the set speed of the cruise control system.

A PCC system can be declared as input to the simulation tool if either the functionalities set out in points (1) and (2) or points (1), (2) and (3) are covered.

8.2

The eleven combinations of the advanced driver assistance systems as set out in Table 12 are input parameters into the simulation tool. Combinations 2 to 11 shall not be declared for SMT transmissions. Combinations No 3, 6, 9 and 11 shall not be declared in the case of APT transmissions.

8.3

Any advanced driver assistance system declared in the input into the simulation tool shall by default be set to fuel economy mode after each key-off/key-on cycle.

8.4

If an advanced driver assistance system is declared in the input into the simulation tool, it shall be possible to verify the presence of such a system based on real world driving and the system definitions as set out in point 8.1. If a certain combination of systems is declared, also the interaction of functionalities (e.g. predictive cruise control plus eco-roll with engine stop-start) shall be demonstrated. In the verification procedure it shall be taken into consideration, that the systems need certain boundary conditions to be “active” (e.g. engine at operation temperature for engine stop-start, certain vehicle speed ranges for PCC, certain ratios of road gradients with vehicle mass for eco-roll). The vehicle manufacturer needs to submit a functional description of boundary conditions when the systems are “inactive” or their efficiency is reduced. The approval authority may request the technical justifications of these boundary conditions from the applicant for approval and assess them for compliance.

The vehicle manufacturer may declare limitations of the total propulsion torque of the whole powertrain referring to the transmission input shaft for a parallel HEV in order to restrict the boosting capabilities of the vehicle.

The declaration of such limitations is allowed only in the case that the powertrain configuration in accordance with point 10.1.1 is “P” or “IHPC Type 1”.

The limitations are declared as additional torque allowed on top of the ICE full load curve dependent on the rotational speed of the transmission input shaft. Linear interpolation is performed in the simulation tool to determine the applicable additional torque between the declared values at two specific rotational speeds. In the rotational speed range from 0 to engine idling speed (in accordance with point 7.1) the full load torque available from the ICE equals only the ICE full load torque at engine idling speed due to the modelling of the clutch behaviour during vehicle starts.

Where such a limitation is declared, values for the additional torque shall be declared at least at a rotational speed of 0 and at the maximum rotational speed of the ICE full load curve. Any arbitrary number of values may be declared in between the range of zero and the maximum rotational speed of the ICE full load curve. Declared values lower than zero shall not be allowed for the additional torque.

The vehicle manufacturer may declare such limitations which match exactly the ICE full load curve by declaring values of 0 Nm for the additional torque.

10.3 Engine stop-start functionality for HEVs

Where the vehicle is equipped with an engine stop-start functionality in accordance with point 8.1.1 considering the boundary conditions in point 8.4, the input parameter P271 in accordance with Table 6 shall be set to true.

11. Transfer of results of the simulation tool to other vehicles

Testing procedure for torque converter (TC)

The torque converter characteristics to be determined for the simulation tool input consist of T pum1000 (the reference torque at 1 000 rpm input speed) and μ (the torque ratio of the torque converter). Both are depending on the speed ratio v (= output (turbine) speed / input (pump) speed for the torque converter) of the torque converter.

For determination of the characteristics of the TC, the applicant for a certificate shall apply the following method, irrespective of the chosen option for the assessment of the transmission torque losses.

To take the two possible arrangements of the TC and the mechanical transmission parts into account, the following differentiation between case S and P shall apply:

Case S	:	TC and mechanical transmission parts in serial arrangement
Case P	:	TC and mechanical transmission parts in parallel arrangement (power split installation)

For case S arrangements the TC characteristics may be evaluated either separate from the mechanical transmission or in combination with the mechanical transmission. For case P arrangements the evaluation of TC characteristic is possible only in combination with the mechanical transmission. However, in this case and for the hydromechanical gears subject to measurement the whole arrangement, torque converter and mechanical transmission, is considered as a TC with similar characteristic curves as a sole torque converter. In the case of measurements together with a mechanical transmission, the speed ratio v and all corresponding values for step widths as well as limits shall be adjusted by taking the mechanical transmission ratio into account.

For the determination of the torque converter characteristics two measurement options may be applied:

(i)	Option A: measurement at constant input speed;

CONFORMITY OF SIMULATION TOOL OPERATION AND OF CO2 EMISSIONS AND FUEL CONSUMPTION RELATED PROPERTIES OF COMPONENTS, SEPARATE TECHNICAL UNITS AND SYSTEMS: VERIFICATION TESTING PROCEDURE

1. Introduction

This Annex sets out the requirements for the verification testing procedure, which is the test procedure for verifying the CO2 emissions of new medium and heavy lorries.

The verification testing procedure consists of an on-road test to verify the CO2 emissions of new vehicles after production. It shall be carried out by the vehicle manufacturer and supervised by the approval authority that granted the licence to operate the simulation tool.

During the verification testing procedure the torque and speed at the driven wheels, the engine speed, the fuel consumption, the engaged gear of the vehicle and the other relevant parameters listed in point 6.1.6 shall be measured. The measured data shall be used as input to the simulation tool, which uses the vehicle-related input data and the input information from the determination of the CO2 emissions and fuel consumption of the vehicle. For the verification testing procedure simulation, the instantaneously measured wheel torque and the rotational speed of the wheels as well as the engine speed shall be used as input. To pass the verification testing procedure the CO2 emissions calculated from the measured fuel consumption shall be within the tolerances set out in point 7 compared to the CO2 emissions from the verification testing procedure simulation. Figure 1 gives a schematic picture of the verification testing procedure method. The evaluation steps as performed by the simulation tool in the verification testing procedure simulation are described in Appendix 1 of this Annex.

As part of the verification testing procedure, the correctness of the vehicle input data set from the certification of CO2 emissions and fuel consumption related properties of the components, separate technical units and systems shall also be reviewed to check the data and the data handling process. The correctness of the input data relating to components, separate technical units and systems relevant for air drag and for rolling resistance of the vehicle shall be verified in accordance with point 6.1.1.

3. Vehicle selection

The number of new vehicles to be tested per year of production ensures that the relevant variations of components, separate technical units or systems used are covered by the verification testing procedure. The vehicle selection for the verification test shall be based on the following requirements:

(a)

The vehicles for the verification test shall be selected out of the vehicles from the production line for which a value of CO2 emissions and fuel consumption has been determined and declared in accordance with Article 9. The components, separate technical units or systems mounted in or on the vehicle shall be out of series production and shall correspond to those mounted at production date of the vehicle.

(b)	The vehicle selection shall be made by the approval authority that granted the licence to operate the simulation tool based on proposals from the vehicle manufacturer.

(c)	Only vehicles with one driven axle shall be selected for verification test.

(d)

It is recommended to include in each verification test relevant data sets of the components of interest and with the highest sales numbers per manufacturer. The components, separate technical units or systems may be verified all in one vehicle or in different vehicles. Apart from the criterion of highest sales numbers, the approval authority mentioned in (b) shall decide whether other vehicles with relevant data sets engine, axle and transmission shall be included in the verification test.

(e)

Vehicles which use standard values for CO2 certification of their components, separate technical units or systems instead of measured values for the transmission and for the axle losses shall not be selected for the verification test as long as vehicles complying with the requirements in points (a) to (c) and using measured loss maps for these components, separate technical units or systems in the CO2 certification, are produced.

(f)

The minimum number of different vehicles with different combinations of verification test relevant data sets to be tested by verification test per year shall be based on the sales numbers of the vehicle manufacturer as set out in Table 1.

Appendix 1

Main evaluation steps and equations as performed by the simulation tool in a verification testing procedure simulation

This Appendix describes the main evaluation steps and underlying basic equations that are applied by the simulation tool in a verification testing procedure simulation.

PART A: Determination of the CVTP factor

For the determination of the CVTP factor as described in point 7.2.2, the calculation procedures as set out below are applied:

Calculation of wheel power

The torque data as read from the processed measurement data in accordance with Table 4 is corrected for the torque meter drift as follows:

where:

i	=	index standing for left and right wheel of the driven axle
Tcorr	=	drift corrected torque signal [Nm]
T	=	torque signal before drift correction [Nm]
Tdrift	=	torque meter drift as recorded during drift check at the end of the verification test [Nm]
t	=	time node [s]
tstart	=	first time stamp in the processed measurement data in accordance with Table 4 [s]
tend	=	last time stamp in the processed measurement data in accordance with Table 4 [s]

The wheel power is calculated from the corrected wheel torque and rotational wheel speed as follows:

where:

i	=	index standing for left and right wheel of the driven axle
t	=	time node [s]
Pwheel	=	wheel power [kW]
nwheel	=	rotational wheel speed [rpm]
Tcorr	=	drift corrected torque signal [Nm]

The total wheel power is then calculated as the sum of the wheel power from left and right wheel:

Determination of the measured brake specific fuel consumption (FCm-c)

The result for “brake specific fuel consumption measured and corrected for a run-in phase” (BSFCm-c) as applied for in 7.2.2 is calculated by the simulation tool as described below.

In a first step the raw value for measured brake specific fuel consumption for the verification test BSFCm is calculated as follows:

where:

BSFCm	=	raw value for measured brake specific fuel consumption in the verification test [g/kWh]
FCm (t)	=	instantaneous fuel mass flow measured during the verification test [g/s]
Δt	=	time increment duration = 0,5 [s]
Wwheel,pos,m	=	positive wheel work measured in the verification test [kWh]

In a second step BSFCm is corrected for the net calorific value (NCV) of the fuel used in the verification test resulting in BSFCm,corr:

where:

BSFCm,corr	=	value for measured brake specific fuel consumption in the verification test corrected and for NCV influence [g/kWh]
NCVmeas	=	NCV of the fuel used in the verification test determined in accordance with point 3.2 of Annex V [MJ/kg]
NCVstd	=	standard NCV in accordance with Table 5 in point 5.4.3.1 of Annex V [MJ/kg]

This correction is applied for all fuel types, i.e. also for Diesel CI engines (see footnote 2 in Table 4a).

In a third step the correction for a run-in phase is applied:

where:

BSFCm-c	=	brake specific fuel consumption measured and corrected for a run-in phase
ef	=	evolution coefficient of 0,98
mileage	=	run-in distance [km]

For dual-fuel vehicles all three evaluation steps are performed separately for both fuels.

Determination of the brake specific fuel consumption simulated by the simulation tool (BSFCsim)

In the verification test mode of the simulation tool the measured wheel power is applied as input to the backward simulation algorithm. The gears engaged during the verification test are determined by calculating the engine speeds per gear at the measured vehicle speed and selecting the gear that provides the engine speed closest to the measured engine speed. For APT transmissions during phases with active torque converter, the actual gear signal from the measurement is used.

The loss models for axle gear, angle drive, retarders, transmissions and PTOs are applied in a similar way as in the declaration mode of the simulation tool.

For power demand of auxiliary units concerning steering pump, pneumatic system, electric system and HVAC system the generic values as implemented per technology in the simulation tool are applied. For calculation of the power demand of the engine cooling fan the following formulas are applied:

Case a) non-electrically driven engine cooling fans:

where:

Pfan	=	power demand engine cooling fan [kW]
t	=	time node [s]
nfan	=	measured rotational speed of the fan [rpm]
Dfan	=	diameter of the fan [mm]
C1	=	7,32 kW
C2	=	1 200 rpm
C3	=	810 mm

Case (b) electrically driven engine cooling fans:

Pfan(t) = P el(t) . 1,05

Pfan	=	power demand engine cooling fan [kW]
t	=	time node [s]
Pel	=	electrical power at the terminals of the engine cooling fan(s) as measured in accordance with point 5.6.1.

In the case of vehicles with engine stop-start events during the verification test, similar corrections for auxiliary power demand and energy to re-start the engine as applied in the declaration mode of the simulation tool are applied.

The simulation of the engines instantaneous fuel consumption FCsim(t) is performed for each 0,5 second time interval as follows:

—	Interpolation from the engine fuel map using measured engine speed and resulting engine torque from the backward calculation including engines rotational inertia calculated from measured engine speed

—

The engine torque demand as determined above is limited to the certified engine full-load capabilities. For those time intervals the wheel power in the backward simulation is reduced accordingly. In the calculation of BSFCsim as set out below this simulated wheel power trace (Pwheel,sim(t)) is taken into consideration.

—	A WHTC correction factor is applied corresponding to the allocation of urban, rural and motorway based on the definitions as given in point 2(8) to 2(10) and the measured vehicle speed.

The brake specific fuel consumption calculated by the simulation tool BSFCm-c as applied in 7.2.2 for calculation of the CVTP factor is calculated as follows:

where:

BSFCsim	=	brake specific fuel consumption determined by the simulation tool for the verification test [g/kWh]
t	=	time node [s]
FCsim	=	engines instantaneous fuel consumption [g/s]
Δt	=	time increment duration = 0,5 [s]
FCESS,corr	=	correction of fuel consumption regarding auxiliary power demand resulting from engine stop start (ESS) as applied in the declaration mode of the simulation tool [g]
Wwheel,pos,sim	=	positive wheel work determined by the simulation tool for the verification test [kWh]

fs	=	Simulation rate = 2 [Hz]
Pwheel,sim	=	Simulated wheel power for the verification test [kW]

In the case of dual-fuel engines, BSFCsim is determined for both fuels separately.

PART B: Determination of the brake specific pollutant emissions

The engine power is calculated from the measured signals for engine speed and engine torque as follows:

where:

Peng,m	=	measured engine power in the verification test[kW]
t	=	time node [s]
neng	=	measured rotational engine speed [rpm]
Teng	=	measured engine torque [Nm]

The positive engine work measured in the verification test is calculated as follows:

Weng,pos,m	=	positive engine work measured in the verification test [kWh]
fs	=	sampling rate = 2 [Hz]
tstart	=	first time stamp in the processed measurement data in accordance with Table 4 [s]
tend	=	last time stamp in the processed measurement data in accordance with Table 4 [s]

The brake specific pollutant emissions measured in the verification test BSEM are calculated as follows:

where:

BSEM	=	brake specific pollutant emissions measured in the verification test [g/kWh]
EM	=	instantaneous pollutant emission mass flow measured during the verification test [g/s]

6. Testing of capacitor systems or representative capacitor subsystems

6.1 General provisions

Capacitor system components of the capacitor UUT may also be distributed in different devices within the vehicle.

The characteristics for a capacitor are hardly dependent on its state of charge or current, respectively. Therefore, only a single test run is prescribed for the calculation of the model input parameters.

6.1.1 Sign convention for current

Measured values of current shall have a positive sign for discharging and a negative sign for charging.

6.1.2 Reference location for ambient temperature

The ambient temperature shall be measured within a distance of 1 m to the capacitor UUT at a point indicated by the component manufacturer of the capacitor UUT.

6.1.3 Thermal conditions

Capacitor testing temperature, i.e. the target operating temperature of the capacitor UUT, shall be specified by the component manufacturer. The temperature of all capacitor cell temperature measuring points shall be within the limits specified by the component manufacturer during all test runs performed.

For capacitor UUT with liquid conditioning (i.e. heating or cooling), the temperature of the conditioning fluid shall be recorded at the capacitor UUT inlet and must be maintained within ±2 K of a value specified by the component manufacturer.

For air cooled capacitor UUT, the temperature at a point indicated by the component manufacturer shall be kept within +0/–20 K of the maximum value specified by the component manufacturer.

The available cooling and/or heating power on the testbench shall be determined based on the following procedures and recorded together with the actual component test data:

(1)	For liquid conditioning from the massflow of the conditioning fluid and the temperature difference over the heat exchanger on the side of the capacitor UUT.

(2)

For electric conditioning from the voltage and current. The component manufacturer may modify the electric connection of this conditioning unit for the certification of the capacitor UUT to enable a measurement of the capacitor UUT characteristics without considering the electric power required for conditioning (e.g. if the conditioning is directly implemented and connected within the capacitor UUT). Notwithstanding these provisions, the required electric cooling and/or heating power externally provided to the capacitor UUT by a conditioning unit shall be recorded.

(3)	For other types of conditioning based on good engineering judgement and discussion with the type approval authority.

6.2 Test conditions

(a)	The capacitor UUT shall be placed in a temperature controlled test cell. The ambient temperature shall be conditioned at 25 ±10 °C;

(b)	The voltage shall be measured at the terminals of the capacitor UUT.

(c)	The thermal conditioning system of the capacitor UUT and the corresponding thermal conditioning loop at the test bench equipment shall be fully operational in accordance with the respective controls.

(d)	The control unit shall enable the test bench equipment to perform the requested test procedure within the capacitor UUT operational limits. If necessary, the control unit program shall be adapted by the capacitor UUT component manufacturer for the requested test procedure.

6.3 Capacitor UUT characteristics test

(a)	After fully charging and then fully discharging the capacitor UUT to its lowest operating voltage in accordance with the charging method specified by the component manufacturer, it shall be soaked for at least 2 hours, but no more than 6 hours.

(b)	The capacitor UUT temperature at the start of the test shall be 25 ± 2 °C. However, 45 ± 2 °C may be selected by reporting to the type approval or certification authority that this temperature level is more representative for the conditions of the typical application.

(c)	After the soak time, a complete charge and discharge cycle in accordance with Figure 2 with a constant current Itest shall be performed. Itest shall be the maximum allowed continuous current for the capacitor UUT as specified by the component manufacturer.

(d)

After a waiting period of at least 30 seconds (t0 to t1), the capacitor UUT shall be charged with a constant current Itest until the maximum operating voltage V max is reached. Then, the charging shall be stopped and the capacitor UUT shall be soaked for 30 seconds (t2 to t3) so that the voltage can settle to its final value V b before the discharging is started. After that the capacitor UUT shall be discharged with a constant current Itest until the lowest operating voltage V min is reached. Afterwards (from t4 onwards) there shall be another waiting period of at least 30 seconds for the voltage to settle to its final value Vc.

(e)	The current and voltage over time, respectively Imeas and Vmeas, shall be recorded at a sampling frequency of at least 10 Hz.

(f)

The following characteristic values shall be determined from the measurement (illustrated in Figure 2):

V a is the no-load voltage right before start of the charge pulse

V b is the no-load voltage right before start of the discharge pulse

V c is the no-load voltage after the end of the discharge pulse

ΔV(t 1), ΔV(t 3) are the voltage changes directly after applying the constant charging or discharging current I test at the time of t 1 and t 3, respectively. These voltage changes shall be determined by applying a linear approximation to the voltage characteristics as defined in detail A of Figure 2 by usage of the least squares method. Data sampling for the straight line approximation shall start once the change in the gradient calculated from two adjacent data points is smaller than 0.5 % when running in the direction of increasing time signal.

Figure 2

Example of voltage curve for the capacitor UUT measurement

ΔV(t 1) is the absolute difference of voltages between V a and the intercept value of the straight-line approximation at the time of t 1.

ΔV(t 3) is the absolute difference of voltages between V b and the intercept value of the straight-line approximation at the time of t 3.

ΔV(t 2) is the absolute difference of voltages between V max and V b.

ΔV(t 4) is the absolute difference of voltages between V min and V c.

6.4. Post-processing of measurement data of the capacitor UUT

6.4.1 Calculation of internal resistance and capacitance

The measurement data obtained in accordance with point 6.3 shall be used to calculate the internal resistance (R) and capacitance (C) values in accordance with the following equations:

Family concept

1. Electric machine systems and IEPCs

1.1. General

A family of electric machine systems or IEPCs is characterised by design and performance parameters. These shall be common to all members within the family. The component manufacturer may decide which electric machine systems or IEPCs belong to a family, as long as the membership criteria listed in this Appendix are respected. The related family shall be approved by the Approval Authority. The component manufacturer shall provide to the Approval Authority the appropriate information relating to the members of the family.

1.2. Special cases

In some cases there may be interaction between parameters. This shall be taken into consideration to ensure that electric machine systems or IEPCs with similar characteristics are included within the same family. These cases shall be identified by the component manufacturer and notified to the Approval Authority. It shall then be taken into account as a criterion for creating a new family of electric machine systems or IEPCs.

In the case of devices or features, which are not listed in paragraph 1.4 and which have a strong influence on the level of performance and/or the electric power consumption, the respective devices or features shall be identified by the component manufacturer on the basis of good engineering practice, and shall be notified to the Approval Authority. It shall then be taken into account as a criterion for creating a new family of electric machine systems or IEPCs.

1.3. Family concept

The family concept defines criteria and parameters enabling the component manufacturer to group electric machine systems or IEPCs into families with similar or equal data relevant for CO2-emissions or energy consumption.

1.4. Special provisions regarding representativeness

The Approval Authority may conclude that the performance parameters and the electric power consumption of the family of electric machine systems or IEPCs can best be characterised by additional testing. In this case, the component manufacturer shall submit the appropriate information to determine the electric machine system or IEPC within the family likely to best represent the family. The Approval Authority may based on this information also conclude that it is required for the component manufacturer to create a new family of electric machine systems or IEPCs consisting of less members in order to be more representative.

If members within a family incorporate other features which may be considered to affect the performance parameters and/or the electric power consumption, these features shall also be identified and taken into account in the selection of the parent.

1.5. Parameters defining a family of electric machine systems or IEPCs

In addition to the parameters listed below, the component manufacturer may introduce additional criteria allowing the definition of families of more restricted size. These parameters are not necessarily parameters that have an influence on the level of performance and/or the electric power consumption.

For the internal design it must be checked if passive cooling elements or air flow at the inner side of the end shields are affected by changes.

For the external design screws, suspension points, flange design have no influence on performance if no passive cooling elements are removed or changed;

(c)	Bearings: Changes allowed as long as number and type of bearings remain the same;

(d)	Shaft: Changes allowed as long as active or passive cooling is not affected;

(e)	High voltage connection: Changes regarding position or type of the high voltage connection allowed;

(f)	Housing: Changes of the housing or number, type and position of screws or mounting points allowed as long as no passive cooling elements are removed or changed;

Maximum torque curve

The torque values at each rotational speed of the maximum torque curve of the parent determined in accordance with paragraph 4.2.2.4 of this Annex shall be equal or higher than for all other members within the same family at the same rotational speed over the whole rotational speed range. Torque values of other members within the same family within a tolerance of +40 Nm or +4 %, whatever is larger, above the maximum torque of the parent at a specific rotational speed are considered as equal;

(n)

Minimum torque curve

The torque values at each rotational speed of the minimum torque curve of the parent determined in accordance with paragraph 4.2.2.4 of this Annex shall be equal or lower than for all other members within the same family at the same rotational speed over the whole rotational speed range.
