Division 4.3 Calculation of electric energy consumption

Original text. Later amendments are not shown.

For the determination of the electric energy consumption based on the current and voltage determined according to Appendix 3 of this Sub-Annex, the following equations shall be used:

ECDC,j=ΔEREESS,jdj

where:

ECDC,j

  • is the electric energy consumption over the considered period j based on the REESS depletion, Wh/km;

    • ΔEREESS,j

  • is the electric energy change of all REESSs during the considered period j, Wh;

    • dj

  • is the distance driven in the considered period j, km;

    • and

    ΔEREESS,j=∑j= 1nΔEREESS,j,i

    where:

    ΔEREESS,j,i

  • is the electric energy change of REESS i during the considered period j, Wh;

    • and

    ΔEREESS,j,i=13600×∫t0tendUtREESS,j,i× Itj,i dt

    where:

    U(t)REESS,j,i

  • is the voltage of REESS i during the considered period j determined according to Appendix 3 to this Sub-Annex, V;

    • t0

  • is the time at the beginning of the considered period j, s;

    • tend

  • is the time at the end of the considered period j, s;

    • I(t)j,i

  • is the electric current of REESS i during the considered period j determined according to Appendix 3 to this Sub-Annex, A;

    • i

  • is the index number of the considered REESS;

    • n

  • is the total number of REESS;

    • j

  • is the index for the considered period, where a period can be any combination of phases or cycles;

    • 13600

  • is the conversion factor from Ws to Wh.
