The expert from Germany, Chair of the IWG on Rechargeable Energy Storage System (REESS), introduced ECE/TRANS/WP.29/GRSP/2014/26 amending ECE/TRANS/WP.29/GRSP/2014/11 and proposing a draft UN Regulation on safety requirements with respect to the electric power train of vehicles of categories L with a maximum design speed exceeding 6 km/h. The expert from IMMA proposed some amendments (GRSP-56-01) superseding ECE/TRANS/WP.29/GRSP/2014/26. Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2014/11 as amended by Annex VI to the session report.

39. The expert from Germany, Chair of the IWG on Rechargeable Energy Storage System (REESS) made a presentation (GRSP-55-29) to introduce ECE/TRANS/WP.29/GRSP/2014/11, aimed at proposing a draft UN Regulation on safety requirements with respect to the electric power train of vehicles of categories L₁ with a maximum design speed exceeding 6 km/h. The expert from IMMA proposed some amendments (GRSP-55-07) to ECE/TRANS/WP.29/GRSP/2014/11. The majority of the Contracting Parties (Australia, France, Germany, the Netherlands, Spain, Sweden and the United Kingdom) rejected the introduction of additional provisions (para. 12 of ECE/TRANS/WP.29/GRSP/2014/11) in the text of the draft UN Regulation, to allow Contracting Parties to continue requiring the proof of compliance for post-crash requirements as proposed by the expert from Japan. GRSP referred GRSP-55-25-Rev.1 back to the IWG (including GRSP-55-22 proposed by the expert from Japan) and agreed to resume consideration of this agenda item at its December 2014 session, on the basis of an updated proposal submitted by the IWG. Finally, GRSP agreed to seek consent from WP.29 at its June 2014 session to extend the mandate of the IWG until June 2015.
