GRSG-107-15
Proposal for amendments to Regulation No. 116

UN R116 specifies operating voltages and voltage limits. Current technology and intelligent battery management systems allow for precise control and definition of these parameters. This includes “intelligent” operating ranges in order to optimize energy management (CO2 emission reduction). Fixed operating voltage ranges are therefore unnecessary or even may hinder efforts for CO2 emission reduction in the future. OICA proposes language to modify the design-restrictive language.

Excerpts from session reports
GRSG | Session 107 | 30 Sep-3 Oct 2014

30. The expert from OICA introduced GRSG-107-15 allowing the introduction of different operating voltage ranges according to the battery technology used. The expert from Germany supported, in principle, the proposal. However, he raised a study reservation on covering high voltage components or not.

GRSG | Session 111 | 11-14 Oct 2016

36. The expert from OICA withdrew ECE/TRANS/WP.29/GRSG/2015/7.

GRSG | Session 109 | 29 Sep-2 Oct 2015

37. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/7 tabled at the previous GRSG session, the expert from OICA announced his intention to provide further evidence on this subject for consideration at the next session of GRSG. GRSG agreed to reconsider GRSG-108-49 under agenda item 17 (para. 51 below).

GRSG | Session 110 | 25-29 Apr 2016

40. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2015/7, the expert from OICA informed GRSG that there was no new information on this subject. He suggested resuming consideration of this subject at the next session of GRSG and volunteered to prepare a revised document. GRSG endorsed that suggestion and agreed to keep document ECE/TRANS/WP.29/GRSG/2015/7 on the agenda as a reference document.

GRSG | Session 108 | 4-8 May 2015

47. Recalling the discussion during the previous GRSG session, the expert from OICA presented ECE/TRANS/WP.29/GRSG/2015/7 proposing to introduce different operating voltage ranges according to the battery technology used. The experts from France and Germany raised the need to limit the voltage range. GRSG noted some comments and study reservations. The Chair invited all experts to send their comments to the expert from OICA and to resume consideration of this subject at the next GRSG session on the basis of a revised document by OICA.
