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. This proposal would allow varying operating voltage ranges according to the battery technology used to remove this restriction impact such advanced designs.
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.
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.
