# Commission Implementing Decision (EU) 2020/1167 of 6 August 2020 on the approval of the technology used in a 48 Volt efficient motor-generator combined with a 48 Volt/12 Volt DC/DC converter for use in conventional combustion engine and certain hybrid electric passenger cars and light commercial vehicles as an innovative technology pursuant to Regulation (EU) 2019/631 of the European Parliament and of the Council) (Text with EEA relevance), Division 3.5: Check against the minimum CO2 savings threshold

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

The type-approval authority shall ensure for each vehicle version fitted with the 48V motor-generator combined with the 48V/12V DC/DC converter that the minimum threshold criterion as specified in Article 9(1)(b) of Implementing Regulation (EU) No 725/2011 and Implementing Regulation (EU) No 427/2014 is met.
When verifying whether the minimum threshold criterion is met, the type-approval authority shall take into account, in accordance with Formula 13, the CO2 savings determined in point 3.2, the uncertainty determined in point 3.3 and, where applicable, a CO2 correction, in the case of a positive mass difference (Δm) between the 48V motor-generator combined with the 48V/12V DC/DC converter and the baseline alternator.
For the purpose of the positive mass correction, the mass of the baseline alternator shall be set to 7 kg.
The manufacturer shall provide to the type approval authority information on the mass of the 48V motor-generator combined with the 48V/12V DC/DC converter as certified by the supplier.
Formula 13
where,
MT is 0,5 g CO2/km as specified in Article 9(1)(b) of Implementing Regulation (EU) No 725/2011 and Commission Implementing Regulation (EU) No 427/2014
is the CO2 savings as determined in point 3.2
uncertainty of the total CO2 savings as determined in point 3.3
CO2 correction, in the case of a positive mass difference (Δm) [kg] between the 48V motor-generator combined with the 48V/12V DC/DC converter and the baseline alternator, calculated in accordance with Table 4:
