Pursuant to GRPE work on vehicle propulsion system definitions (VPSD informal group; see document WP.29-165-17), this proposal would update the definition of the acronym “REESS” to refer to “rechargeable electrical energy storage system” across the passive safety regulations and currently proposed texts that make use of this acronym. (REESS had previously referred generically to “rechargeable energy storage systems”.)

Proposed text for the new UN Regulation on the safety of electric motorcycles and related vehicles.
