Proposal to modify test procedures for the Alternative Method using heavy-duty chassis dynamometer to determine Usable Battery Energy (UBE) and battery durability requirements for electrified heavy-duty vehicles. Changes include specifications for dynamometer settings, test room conditions, cooling fan requirements, driver breaks, battery preparation and pre-conditioning, soak and charge procedures, discharge test cycles for both plug-in electric vehicles (HD-PEVs) and optimized charge-sustaining hybrid electric vehicles (HD-OVC-HEVs), test termination criteria, and measurement device requirements. The document provides test procedures, tables for driver break allowances based on distance and driving time, and detailed formulas for calculating battery energy changes and break-off criteria.

Document presents preliminary views on minimum performance requirements for in-vehicle battery durability under Euro 7 heavy-duty vehicle standards. It outlines implementation timeline for the OMNIBUS proposal in first and second phases, with application dates of 1 January 2030 for the first phase and 1 January 2035 for the second phase. Brake emissions and tyre abrasion requirements are addressed, including UN Regulation No. 186 application dates for C2 and C3 class tyres. Reporting and review provisions under Article 18 are included. The document notes that the order of items and timeline indications are preliminary and for discussion purposes only.

Status update on Euro 7 implementation for light-duty and heavy-duty vehicles. For LDV (M₁, N₁), application begins 30 months after Euro 7 entry into force for new types (29 November 2026) and 42 months for all new vehicles (29 November 2027). For HDV (M₂, M₃, N₂, N₃, O₃, O₄), application begins 48 months after entry into force for new types (29 May 2028) and 60 months for all new vehicles (29 May 2029). Small Volume Manufacturers comply from 1 July 2030 (M₁, N₁) and 1 July 2031 (M₂, M₃, N₂, N₃). Brake emissions apply 1 January 2030 for LDV and 1 January 2030–1 January 2035 for HDV. Tyre abrasion (UN R186) applies 1 July 2028 for C1 class tyres, 1 April 2030 for C2 class, and 1 April 2032 for C3 class.

Session agenda for the 100th meeting of the Electric Vehicles and the Environment Informal Working Group on 13 October 2026. The agenda covers status reports and presentations on UN GTR 22, UN GTR 21, and UN GTR 25, with discussion of Euro 7 review clause, readiness monitoring, and regulatory topics including MPRs, energy throughput, and Part C virtual distance verification.

Proposal to add para. 8.1.2. to specify required measurements for the test vehicle including onboard measurement data permissibility and minimum requirements, and add para. 8.1.2.1. to specify measurements specific to TP1 including electrical current and voltage at REESS or inverter inputs, ICE speed, intake manifold pressure, and fuel flow rate, and DC/DC converter measurement options. The amendments ensure consistency with other paragraphs in the regulation such as para. 6.9.2.1. and Annex 1, Appendix 2, 9.1.1.
