# Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance), Division 1.2.1: Charge-sustaining fuel energy for NOVC-HEVs and OVC-HEVs


The charge-sustaining energy content of the consumed fuel for NOVC-HEVs and OVC-HEVs shall be calculated using the following equation:
Efuel,CS=10× HV× FCCS,nb× dCSwhere:
Efuel,CSis the charge-sustaining energy content of the consumed fuel of the applicable WLTP test cycle of the charge-sustaining Type 1 test, Wh;
HVis the heating value according to Table A6.App2/1, kWh/l;
FCCS,nbis the non-balanced charge-sustaining fuel consumption of the charge-sustaining Type 1 test, not corrected for the energy balance, determined according to paragraph 6. of Sub-Annex 7, using the gaseous emission compound values according to Table A8/5, step no. 2, l/100 km;
dCSis the distance driven over the corresponding applicable WLTP test cycle, km;
10conversion factor to Wh.
