GRSP/2012/11 proposes to correct text for electric vehicles in UN Regulation Nos. 12, 94, 95 and 100, replacing the word “power train” with “occupants” in the referenced rules. This document replaces ‘registration’ with ‘approval’ in transition provisions in accordance with WP.29 guidelines.

Text from the International Organization of Motor Vehicle Manufacturers (OICA) proposing to remove unnecessary constraints to electric vehicle systems having a working voltage of 48 V and to adapt the safety provisions to this technology.

Proposal to clarify the requirements of UN R100 specified under paragraph 5.1.1. This paragraph describes the general requirements for the protection of all high voltage parts, including the obligation that such protection against live parts cannot be opened without the use of tools. If connectors can be opened without use of tools or if they do not satisfy the IPXXD/IPXXB protection limits, the provisions of 5.1.1.3 have to be met.

Presentation of issues raised during discussions of the GRE Task Force on EMC requirements with regard to the application of several UN Regulations to trolley buses depending upon their configuration (e.g., dual-mode operation either connected to overhead cables or in standard bus mode).

Comparison of provisions in the draft proposals prepared by China and by OICA and in UN R100 on battery electric vehicle safety.

Proposal to amend the transitional provisions in order to explicitly confirm that approvals granted prior to the respective supplements to the 01 and 02 series of amendments and the establishment of the new guidelines on UN Regulation procedures (documents WP.29/2017/107 including Corrigendum 1 and Addendum 1) will continue to be accepted. This amendment thus confirms the understanding that the new procedures apply only to new approvals and do not affect previous approvals.

Amended proposal for formal document WP.29/2018/134 on transitional provisions, specifically to correct an error regarding new series type approval transition provisions which should have read “2012” rather than “2010” as erroneously used in the original submission.

Proposal to clarify that the warning signal to alert a driver of an M₂ or M₃ vehicle with more than 22 seating positions if the vehicle is in active-driving-possible mode when the driver leaves the seat shall be activated upon leaving the seat, not the vehicle.

Proposal to streamline the Regulation by eliminating redundant requirements and their test procedures as well as to clarify the possible alternative methods to improve the efficiency of the tests: Delete paragraphs 6.2. and 6.3., delete paragraph 6.5., delete paragraph 6.10., reserve paragraphs 9A, 9B, and 9E, delete paragraph 6.14., amend paragraph 6.15. to add comprehensive thermal propagation verification procedures including risk management analysis alternatives, add paragraph 6.16. for REESS and vehicle communication compatibility, add new Part III (para. 7.) for approved REESS installation requirements, renumber existing paragraphs 8.–13. as paragraphs 8.–13. and add corresponding section numbering, amend scope provisions to clarify application to vehicles of categories M, N, and O with specified e-axle battery provisions, add vehicle category O definitions including “e-axle” and “trailer load compartment,” amend various paragraphs to reference vehicles of categories O₃ and O₄, amend protection requirements to include trailer load compartments, amend over-discharge and overcharge test procedures to permit sequential execution, amend isolation resistance measurement requirements to exempt measurement when isolation resistance monitoring systems are installed and confirmed functional, clarify SOC adjustment procedures to permit alternative ambient temperatures when highest SOC is achievable independently, add labelling requirements for vehicles of categories M₂/N₂ and M₃/N₃ in accordance with ISO 17840-4:2018, add provisions for Automated Driving System (ADS) features and warnings, add provisions for vehicles of category Y regarding mechanical integrity validation at component level, amend Annex 1 Part 2 to revise installation restriction references, add Annex 9K describing four thermal propagation trigger methods with four appendices, and add Annex 10 specifying label provisions for electric power train vehicles.

Proposal to provide guidance for interpretation of “Type of REESS” (Rechargeable Electrical Energy Storage System) as defined in UN R100 para. 2.48. The document establishes that differences in REESS should be evaluated from the perspective of substantial impact on safety performance. It describes key elements for assessing impact on safety within each essential aspect: manufacturer responsibility, cell chemistry/capacity/physical dimensions, cell number/connection/support, casing construction/materials/dimensions, and ancillary devices. The guidance provides examples of changes not causing or potentially causing significant differences, including production location changes, multi-sourcing of cells, and process improvements.

Supporting presentation for proposals to remove para. 6.2. and Annex 9A, remove para. 6.3. and Annex 9B, remove para. 6.5. and Annex 9E including Appendix 1, remove para. 6.10. and Annex 9J, exempt from isolation resistance measurements after each test, allow sequential execution of over-discharge and overcharge tests, remove standard cycle after each test, unify thermal event warning requirement by removing para. 6.14., and allow alternative conditions for ambient temperature for SOC adjustment. The document also proposes guidance on REESS type definition.
