# Commission Implementing Decision (EU) 2019/314 of 21 February 2019 on the approval of the technology used in SEG Automotive Germany GmbH High efficient 48V motor generator (BRM) plus 48V/12V DC/DC converter for use in conventional combustion engine and certain hybrid 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), Division 3.4: Calculation of the CO2 savings

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

The CO2 savings of the 48 V motor generator plus the 48V/12V DC/DC converter shall be calculated in accordance with Formula 7:
Formula 7
C CO 2 = ΔP m × V Pe × CF v Where:
v Mean driving speed of the NEDC [km/h], which is 33,58 km/h
VPe Consumption of effective power specified in Table 2:
