Explanations regarding the table in attachment 3 to FCS information document

The positions of sensors are specified in a schematic manner in figure 5. All values - except for the duration, ARS and REE - are arithmetic mean values at each OP determined over the analysis time, tanlys, defined in accordance with point 7.3.4.4 (i.e. before the averaging step of ascending and descending). For the SCOP the averaging time frame shall be defined by the same time frame length as for the analysis time and shall be located just before the transition to the subsequent OP01a.

The minimum precision requirements of sensors are indicated by a type classification in the respective column in Table 2. The following types are distinguished where type I has the highest precision and type III the lowest:

Type I: accuracy according to Table 1 of this Annex;
Type II: accuracy of integrated and accessible sensors (i.e. all FCS integrated automotive sensors are of type II);
Type III: not applicable or precision not specified: precision according to best practice / common sense.

If the same value is measured by more than one sensor only the numbers determined by the sensor with the higher precision shall be documented. If in the comment column the phrases ‘if applicable’ / ‘if accessible’ are set out, no additional sensors need to be installed.

Appendix 8

Standard values for electric machine system

The following steps shall be performed to generate the input data for the electric machine system based on standard values:

- — Step 1: UN Regulation No. 85 shall be applied for this Appendix unless stated otherwise.

- — Step 2: The maximum torque values as a function of the rotational speed shall be determined from the data generated in accordance with paragraph 5.3.1.4 of UN Regulation No. 85. The data shall be extended in accordance with point 4.3.2 of this Annex.

  • — Step 3: The minimum torque values as a function of the rotational speed shall be determined by multiplying the torque values from Step 2 above by minus one.
  • — Step 4: The maximum 30 minutes continuous torque and the corresponding rotational speed shall be determined from the data generated in accordance with paragraph 5.3.2.3 of UN Regulation No. 85 as average values over the 30 minutes period. In case no value for the maximum 30 minutes continuous torque in accordance with Regulation No. 85 can be determined or the value determined is 0 Nm, the applicable input data shall be set to 0 Nm and the corresponding rotational speed shall be set to the rated speed determined from the data generated in accordance with Step 2 above.
  • — Step 5: The overload characteristics shall be determined from the data generated in accordance with step 2. The overload torque and the corresponding rotational speed shall be calculated as average values over the speed range where the power is equal or greater than 90 % of the maximum power. In case the resulting overload torque is lower than continuous torque, the overload torque shall be set to the 30 minutes continuous torque resulting from step 4. The overload duration t0_maxP shall be defined by the whole duration of the test run performed in accordance with step 2 multiplied by a factor of 0,25.

  • The test procedure shall be performed in accordance with point 7.3.4 following all principles set out therein but with a reduced number of OPs to be measured. The manufacturer may as an alternative option select to measure the complete set of OP from the original component certification following the exact same provisions and boundary conditions as applied during the original component certification and documented in the information document set out in Appendix 7.
  • The target OPs to be measured shall be defined by the normalized set power, P@OPxxnorm, calculated in accordance with the following equation:

  • where:
P@OPxx : target electrical FCS power output at a certain OP between lowest and highest with the identifier xx running from 01 to nop
--- --- ---
P@OPnop : target electrical FCS power output at highest OP
  • The target OPs to be measured for CoP testing shall be selected out of the target OPs from the original component certification defined in accordance with point 7.3.4.1 and recorded in the information document set out in Appendix 7 during component certification. The target OPs to be selected shall be defined by the normalized set power values in accordance with the following points (a) to (e):
  • (a) OP next lower or equal to 0,15 In case there is no OP lower or equal to 0.15 existing, the lowest OP out of the target OPs from the original component certification shall be used.
  • (b) OP next higher to 0,15 In case this OP is already selected for CoP under point (a), the next highest OP out of the target OPs from the original component certification shall be used.
  • (c) OP closest to 0,4 In case the next lower and next higher OP are exactly equidistant to 0.4, the next lower OP shall be used for CoP testing. In case this OP is already selected for CoP under point (b), the next highest OP out of the target OPs from the original component certification shall be used.
  • (d) OP next lower to 0,7 In case this OP is selected for CoP under point (c), the next highest OP out of the target OPs from the original component certification shall be used.
  • (e) OP equal to 1,0 In case this OP is already selected for CoP under point (d), it shall be measured only once. With the target OPs to be measured for CoP testing, the provisions of point 7.3.4 including all its subpoints shall apply in order to determine the values of P FCS, avg and

Image omitted; see official source . In that context, target OPs to be measured with the normalized set power of 1 shall be considered as OPnop and only measured once whereas all other target OPs shall be measured twice (i.e. in the ascending and descending path).

  • 5.7.3Post-processing of results
  • All values of of P FCS, avg determined in accordance with point 5.7.2 shall be processed in accordance with point 7.5 of this Annex to derive the values of final effective electrical power output P*el,FCS,net.
  • Subsequently, the resulting values of P*el,FCS,net and

Image omitted; see official source determined in accordance with point 5.7.2 shall be corrected for uncertainty deviation of CoP measurement equipment in accordance with points (a) to (f):

- (a) The difference in measurement equipment uncertainty in percent between component type approval and CoP testing in accordance with this Appendix shall be calculated for the measurement systems used for current, voltage and fuel mass flow.

- (b) The difference in uncertainty in percent referred to in subpoint (a) shall be calculated for both, the analyzer reading and the maximum calibration value defined in accordance with point 3.1 of this Annex.

- (c) The total difference in uncertainty for electrical power shall be calculated in accordance with the following equation:

- 5.7.4Evaluation of results
  • For each target OP for CoP testing, the specific fuel consumption, SFCCoP, shall be calculated from the corresponding values of Pel,CoP and mF,CoP determined in accordance with point 5.7.3 by dividing mF,CoP by Pel,CoP.
