Original text. Later amendments are not shown.

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:
