Division 4.4.5 Actual charge-depleting range for OVC-HEVs

The actual charge-depleting range shall be calculated using the following equation:

R_{CDA} = \sum_{c = 1}^{n - 1} d_{c} + (\frac{M_{CO2,CS} - M_{CO2,n,cycle}}{M_{CO2,CS} - M_{CO2,CD,avg,n - 1}}) \times d_{n}

where:

R_CDA

is the actual charge-depleting range, km;

M_CO2,CS

is the charge-sustaining CO₂ mass emission according to Table A8/5, step no. 7, g/km;

M_CO2,n,cycle

is the CO₂ mass emission of the applicable WLTP test cycle n of the charge-depleting Type 1 test, g/km;

M_{CO2,CD,avg,n–1}

is the arithmetic average CO₂ mass emission of the charge-depleting Type 1 test from the beginning up to and including the applicable WLTP test cycle (n-1), g/km;

d_c

is the distance driven in the applicable WLTP test cycle c of the charge-depleting Type 1 test, km;

d_n

is the distance driven in the applicable WLTP test cycle n of the charge-depleting Type 1 test, km;

is the index number of the considered applicable WLTP test cycle;

is the number of applicable WLTP test cycles driven including the transition cycle according to paragraph 3.2.4.4. of this Sub-Annex;

and

M_{CO2,CD,avg,n - 1} = \frac{\sum_{n - 1}^{c = 1} (M_{CO2,CD,c} \times d_{c})}{\sum_{n - 1}^{c = 1} d_{c}}

where:

M_{CO2,CD,avg,n–1}

is the arithmetic average CO₂ mass emission of the charge-depleting Type 1 test from the beginning up to and including the applicable WLTP test cycle (n-1), g/km;

M_CO2,CD,c

is the CO₂ mass emission determined according to paragraph 3.2.1. of Sub-Annex 7 of the applicable WLTP test cycle c of the charge-depleting Type 1 test, g/km;

d_c

is the distance driven in the applicable WLTP test cycle c of the charge-depleting Type 1 test, km;

is the index number of the considered applicable WLTP test cycle;

is the number of applicable WLTP test cycles driven including the transition cycle according to paragraph 3.2.4.4 of this Sub-Annex;
