Commission Implementing Decision (EU) 2017/785 of 5 May 2017 on the approval of efficient 12 V motor-generators for use in conventional combustion engine powered passenger cars as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance)

5. Calculation of the statistical error

The statistical errors in the results of the testing methodology caused by the measurements shall be quantified. For each operating point the standard deviation shall be calculated in accordance with the following Formula 7:

Formula 7

The standard deviation of the efficiency value of the efficient 12 V motor generator ( ) shall be calculated in accordance with the following Formula 8:

Formula 8

The standard deviation of the motor generator efficiency ( ) leads to an error in the CO2 savings ( ). That error is calculated in accordance with the following Formula 9:
