# Commission Implementing Decision (EU) 2020/1232 of 27 August 2020 on the approval of the efficient generator function used in 12 Volt motor-generators for use in passenger cars and light commercial vehicles, including certain hybrid electric vehicles and vehicles capable of running on alternative fuels, as an innovative technology pursuant to Regulation (EU) 2019/631 of the European Parliament and of the Council (Text with EEA relevance), Division: Formula 1

Extent: E+W+S+N.I.

where, for each operating point i,
Ui is the voltage [V];
Ii is the current intensity [A];
Μi is the torque [Nm];
ni is the rotational frequency [min-1].
For each operating point, the measurements shall be performed at least five times consecutively and the efficiency shall be calculated for each of those measurements () with j being the index referring to one set of measurements.
For each operating point, the average of those efficiencies () shall be calculated.
The efficiency of the 12V motor-generator (ηMG) [%] shall be calculated in accordance with Formula 2.
