# 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 4.1


To apply the correction function, the electric energy change ΔTREESS,j of a period j of all REESSs shall be calculated from the measured current and the nominal voltage:
ΔEREESS,j=∑i=1n ΔEREESS,j,i
where:
ΔEREESS,j,iis the electric energy change of REESS i during the considered period j, Wh;
and:
ΔEREESS,j,i=13600×UREESS×∫t0tend Itj,idt
where:
UREESSis the nominal REESS voltage determined in accordance with IEC 60050-482, V;
I(t)j,iis the electric current of REESS i during the considered period j, determined in accordance with paragraph 2. of this Appendix, A;
t0is the time at the beginning of the considered period j, s;
tendis the time at the end of the considered period j, s.
iis the index number of the considered REESS;
nis the total amount of REESS;
jis 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;
13600is the conversion factor from Ws to Wh.
