• 7.3.3Methodology

• The certification test procedure aims to record static data on a stabilized FCS at a certain number of different operating points. Each operating point shall be specified by its set-point for the electrical FCS power output.

• During the certification, the FCS shall be operated in its standard operation conditions, as documented by the manufacturer in accordance with Appendix 7.

• The voltage level at the interface between the PCS and the external electric components shall be determined by the lower and upper voltage level as specified in Table 10 to:

• UPCS, out = 0,5 * (UPCS, out, upper + UPCS, out, lower)

• In case the PCS is not included in the UUT, UPCS, upper and UPCS, lower shall be derived from the requirement specifications for the DC/DC converter as provided by the manufacturer.

• The manufacturer shall declare in accordance with Appendix 7 realistic boundary conditions for normal operation of the FCS for in-vehicle usage.

• 7.3.4Test procedure description

• The entire test procedure shall be performed without interruption and the entire test shall be recorded.

• The manufacturer shall specify the operating point (OP) with the lowest (OP01) and highest (OPnop) electrical FCS power output to be measured as certification test range. That range shall cover the whole span for real world operation in vehicle application.

• 7.3.4.1Definition of operating points

• The FCS shall be tested on a defined number of OPs, nop, which shall be equal or greater than 12.

• The OP with the lowest (OP01) and highest (OPnop) electrical FCS power output shall be measured mandatorily.

• The remaining number of OP shall be distributed within the certification test range. The distribution of OPs does not need to be equidistant but shall enable a good interpolation of the fuel consumption over the whole certification test range. In regions of elevated non-linear relationship between FCS power output and fuel consumption a smaller step size between set-points is allowed.

• The naming convention of the operation set-points shall be defined as:

P@OP01	:	target electrical FCS power output at OP01
---	---	---
P@OPxx	:	target electrical FCS power output at any OP between lowest and highest with the identifier xx running from 02 to (nop -1)

| | | |

| --- | --- | --- | | P@OPnop | : | target electrical FCS power output at OPnop |

- The maximum step size between two adjacent OPs, Step-sizemax, shall be defined in accordance with the following equation:

• Step-sizemax < 0,20 * (P@OPnop – P@OP01)

• 7.3.4.2Conditioning phase

• Prior to the actual test the system shall be operated at least 60 minutes at a SCOP. That set-point (electrical FCS power output target value) shall lie between 40 % and 60 % of the upper operating point for certification, OPnop, and shall be defined by the manufacturer.

• 7.3.4.3Sequence of operating points

- The series shall start from OP01 and shall be continued in ascending order up to OPnop and then back again to the lowest OP in descending order. The entire duration is dependent on the stabilization time at the individual OPs.

- Figure 3 depicts the whole test sequence in a schematic manner.

Figure 3

Sequence of OP

• 7.3.4.4Steps to be performed at each operating point

• In order to determine the fuel consumption at each OP in a reproducible manner, a sufficient stabilization time at each OP shall be defined by the manufacturer to achieve adequate stability of the system. The stabilization time shall be defined as individual value for each OP to be measured and shall be between tstab,min = 300 - 1 s and tstab,max = 1 800 + 1 s. Both stabilization times for the same OP in the ascending and descending part shall be within a tolerance of 2 seconds. The stabilization time for a measured OP shall start immediately after the ramp from the previous setpoint is completed. The analysis time is required to gain average values avoiding measurement noises and other instationary effects. Therefore, the analysis time shall be set to tanlys = 180 ± 1 s and shall start after the stabilization time. The measured values within that time span shall fulfil the stability criteria set out in point 7.3.4.5 unless the maximum stabilization time of tstab,max = 1 800 + 1 s is applied. After the analysis time, the standby time used for a proper separation from the next load point shall follow and the duration shall be defined as tstb = 10 ± 1 s.

• Figure 4 depicts the steps to be performed at each OP.

- 7.3.4.5Stability Criteria

To determine the degree of steadiness of the fuel consumption, metered by means of a test cell sensor at the fuel inlet of the FCS (

Image omitted; see official source

FPS as specified in Figure 5), a least squares linear regression shall be performed, the independent variable being the time and the dependent variable being the fuel flow, in accordance with points 7.3.6.1 and 7.3.6.2. Based on the regression analysis, the following two stability indicators shall be calculated in accordance with point 7.3.6.3:

• (a) absolute value of the relative slope of the estimate (ARS), which represents the slope;

• (b) relative error of estimate (REE), which represents the degree of fluctuations of the monitored item.

• The values for the stability criteria shall be calculated in accordance with point 7.3.6.3. The OP shall be considered as stable if both indicators are below a specific threshold value within the defined analysis time frame. The threshold values for both stabilization indicators ARS and REE shall be calculated in accordance with the threshold values set out in Table 11. For the calculation of the REE, the normalized set power at any OP compared to the highest OP shall be defined as:

Image omitted; see official source

Table 11

Threshold values

Indicator:	Threshold Value:
ARS	7,0E-5 sE-1
REE	Image omitted; see official source

• In case the proof of stability at any OP fails, the test shall be repeated with an enlarged or the maximum stabilization time in accordance with point 7.3.4.4.

• 7.3.4.6Transition slope between two operating points

• The transition from one set-point to the next shall be executed with a moderate slope. Suitable slopes for up- and down-ramping of the set-point shall be specified by the manufacturer. The objective shall be to set a slope that facilitates a quick stabilization on the subsequent operating point. No restrictions shall apply to the value of the transition slope or to the shape of that slope. In case no transition slope is specified by the manufacturer, the RTS shall be set to +0,002 ±0,0004 s^-1 during ramp-up and 0,002  ±0,0004 s^-1during ramp-down.
