Division 4.1 F1

To apply the correction function, the electric energy change ΔT_REESS,j of a period j of all REESSs shall be calculated from the measured current and the nominal voltage:

${ΔE}_{REESS,j} = \sum_{i = 1}^{n} {ΔE}_{REESS,j,i}$

where:

ΔE_REESS,j,i

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

and:

${ΔE}_{REESS,j,i} = \frac{1}{3600} \times U_{REESS} \times \int_{t_{0}}^{t_{end}} I {(t)}_{j,i} dt$

where:

U_REESS

is the nominal REESS voltage determined in accordance with IEC 60050-482, V;

I(t)_j,i

is the electric current of REESS i during the considered period j, determined in accordance with paragraph 2. of this Appendix, A;

t₀

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

t_end

is the time at the end of the considered period j, s.

is the index number of the considered REESS;

is the total amount of REESS;

is the index number for the considered period, where a period shall be any applicable cycle phase, combination of cycle phases and the applicable total cycle;

\frac{1}{3600}

is the conversion factor from Ws to Wh.
