Proposal for establishing two informal working groups addressing the safety and environmental requirements for electric vehicles to enhance regulatory cooperation including developing global technical regulations in the framework of the 1998 Agreement.

Comparison between outline (Part B) and OICA GTR draft.

OICA draft GTR from the second EVS session marked up with comments by Japan.

This document is a progress report to the Executive Committee of the 1998 Agreement (AC.3) on the development of the draft gtr for electric vehicle safety (EVS), as recommended by the Working Party on Passive Safety (GRSP) at its May 2014 session. An extension of the mandate for the informal working group (IWG) is requested.

Progress report on the development of GTR concerning safety aspects of electric vehicles.

Proposal from Japan for the use of an isolation resistance monitor as an alternative to water flooding and washing tests in evaluating electric vehicle protection against water.

Draft text as approved by GRSP for anticipated adoption during the November 2017 WP.29 session.

Discussion of issues related to the transposition of the EVS GTR-Phase 1 provisions, especially the scope/application and marking requirements, into UN R100.

Discussion to kick off phase 2 work on defining uniform methods for assessing the risk of thermal propagation across the REESS.

Japan responses to the EVS informal group request for input concerning thermal propagation testing across electric vehicle battery cells. (EVS informal group action item 9 from the 14th session)

Summary table current research projects in Japan regarding electric vehicle REESS thermal propagation testing. (EVS informal group session 14 action item 11)

Presentation of Japan research into thermal propagation. (Action item 1 from the 14th EVS informal group session)

Japan input on thermal propagation and methods of initiation in battery system.

Summary list of WP.29 parties’ EV research activities.

Japan response to EVS action item 2: “All members identify specific questions in the white paper to contracting parties for agreement in order to continue with research.”

Japan’s position on the alignment of UN R137 with GTR 20 on electric vehicle safety.

Proposal to amend the requirements concerning post-crash electrical safety in the event of frontal collision. The proposal aligns post-crash electrical safety requirements with GTR 20 and aligns administrative provisions with Revision 3 of the 1958 Agreement. The amendments would not affect approvals for vehicles without high-voltage electric power trains.

Proposal to amend the requirements concerning post-crash electrical safety in the event of lateral collision. The proposal aligns post-crash electrical safety requirements with GTR 20 and aligns administrative provisions with Revision 3 of the 1958 Agreement. The amendments would not affect approvals for vehicles without high-voltage electric power trains.

Proposal to transpose the electrical safety requirements of GTR 20 into UN R100 and align administrative provisions with Revision 3 of the 1958 Agreement. The proposal provides for a 2-3 year transitional period. The proposal also integrates the amendments to UN R100 provided in document GRSP/2019/17.

Consolidated revision of UN R100 incorporating the proposal to transpose the electrical safety requirements of GTR 20 into UN R100 and align administrative provisions with Revision 3 of the 1958 Agreement. The proposal provides for a 2-3 year transitional period. The proposal also integrates the amendments to UN R100 provided in document GRSP/2019/17.

Proposal to amend the requirements concerning post-crash electrical safety in the event of frontal collision. The proposal aligns post-crash electrical safety requirements with GTR 20 and aligns administrative provisions with Revision 3 of the 1958 Agreement. The amendments would not affect approvals for vehicles without high-voltage electric power trains.

Proposal to introduce provisions on thermal propagation as a result of a single cell thermal runaway.

Proposal to amend para. 9.(a) to clarify expansion of the protection scope of electrical and battery safety, including thermal propagation in cases of V2X, parking, and charging. The modification addresses new vehicle functionalities like V2X, defined in UN GTR No. 22, where traction batteries cover external power and energy demand. Additional requirements must be added, including isolation resistance requirements for coupling systems for charging the REESS, as defined in para. 5.1.1.2.4.4. of UN GTR No. 20.
