Proposal to establish a Task Force on Swappable Batteries (TFSB) under GRPE. The task force will review WP.29 regulations and international standards to identify technical requirements for swappable-battery vehicles, focusing on commercial vehicles. It will define vehicle types, clarify vehicle type approval processes, and develop guidance documents. The task force will coordinate with other working groups including GRSP and GRVA, with deliverables expected by October 2027.

Proposal optimises the measurement accuracy requirements for chassis dynamometer equipment and the measurement acquisition of the
intake manifold pressure in system power testing for high-performance vehicles and makes editorial corrections.

Review of the different proposed amendments (03/04 series with different Supplements) to the regulations

Proposal to amend Appendix 5 (Devices for monitoring on board the vehicle the consumption of fuel and/or electric energy) of Working Document ECE/TRANS/WP.29/2026/153 to specify parameters to be determined, stored and made available by OBFCM devices for pure ICE and NOVC-HEVs, OVC-HEVs, PEVs, NOVC-FCHVs, OVC-FCHVs, and mono-fuel gas vehicles. The modification excludes a manufacturer-specific parameter and aligns with international standards for OBFCM requirements.

Explains the proposal 95-15

Japan presents positions on working documents for UN R168 (Real Driving Emissions). Japan does not accept the Level 1C concept, proposes deleting the type-approval scheme for equipment to eliminate unnecessary burden, and recommends adding technical requirements for laboratory equipment instead. Japan expresses technical concerns regarding sampling line temperature limits, text structure requiring restructuring, and hydrogen ICE provisions including dry-wet correction applicability and trip validity methods for bi-fuel vehicles.

Proposal to amend para. 1.1.3. of Annex C1 to clarify that the method for customer values shall be determined in agreement with the authorities only in the case that the specified methods are not applied, and amend paras. 2.1.2. and 3.1.2. of Annex C1 Appendix 2 to correct the technical error in the determination of UBEcertified by specifying that UBEcertified shall be rounded to the nearest whole number if the unit is Wh or to three significant numbers if the unit is kWh, and when the interpolation method is applied, UBEcertified shall be determined by selecting the maximum amongst vehicle H and vehicle L, and if applicable, vehicle M.

Proposal to amend para. 3.1.2. of Annex 5 to clarify the verification procedure for SOCR/SOCE monitors by specifying that electric range and UBE values shall be measured at the time of verification with related monitor values collected before and after the verification test procedure, that indicator values collected after the verification test procedure shall not be considered in Part A verification, and that measured SOCR and measured SOCE values shall be determined by dividing measured values for electric range and UBE by certified values for electric range and UBE respectively, expressed in per cent.

Proposal to add para. 8.1.2. to specify required measurements for test vehicles, including use of onboard measurement data as an alternative to measurement devices for engine speed, intake manifold pressure, and fuel flow rate when accuracy and frequency meet minimum requirements, and to add para. 8.1.2.1. to specify measurements specific to TP1 including electrical current and voltage at REESS or inverter inputs and ICE speed, intake manifold pressure, and fuel flow rate.

The Task Force on Swappable Battery shall review WP.29 regulations and identify technical requirements necessary for swappable-battery vehicles intended for mass production, compile them into a list, define vehicle types for swappable-battery-compatible vehicles, identify applicable regulations, clarify the process for handling such vehicles and batteries as a special type of Vehicle Type Approval under WP.29, discuss treating batteries as independent type approval units for both swappable and in-vehicle batteries, coordinate activities with EVS Phase 3 scheduled to start in November 2026, cooperate with EVE IWG activities, and develop a guidance document to be proposed to WP.29 to initiate regulatory work. Terms of Reference will be finalized and proposed to GRPE in April 2027, and status of other items will be reported in October 2027.

Document presents preparation for a Task Force on swappable batteries under GRPE. It outlines considerations of sustainability from environmental and customer acceptability perspectives, identifies issues requiring regulatory framework including vehicle and battery approval processes, safety requirements for swapping operations, performance and durability standards, cyber security measures, and compatibility checking. A two-step approach is proposed: identifying work items and drafting Terms of Reference. The Task Force will review WP.29 regulations, identify technical requirements for swappable-battery vehicles, define vehicle types for type approval, and collaborate with other WP.29 bodies. Japan and China are initial Co-Chairs; other Contracting Parties are welcomed to join. Timeline spans October 2026 through May 2027 with discussions beginning at GRPE-95.

Corrections to align the unit of each factor in the equations 8-2, 8-4, 8-6, and 8-10 in paragraph 8 and to Annex 13, paragraph 1, Figure A13-1 where, in the upper figure for “gear use during acceleration phases”, the acceleration gear 1 incorrectly starts from zero.

Final draft version of the WLTP global technical regulation for review and eventual approval at the Working Party on Pollution and Energy special session set for 14 November 2013.

Proposal from the European Commission and Japan for a new UN Regulation based on discussions with the Informal Working Group on Global Real Driving Emissions.

Proposal to correct the improper or confusing provisions described in Amendment 3 to UN GTR No.4.

Proposal to introduce particle number requirements and limits for Level 1B. The proposal also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 and other adaptations to technical progress.

Proposal to ensure that Level 2 is the latest version of this Regulation and is therefore subject to mutual recognition under the 1958 Agreement, given that there is a concurrent proposal to for an 02 series of amendments which introduces particle number requirements and limits for Level 1B. This proposal for a 03 series of amendments also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 as well as other adaptations to technical progress.

Proposal to update the previously adopted text (GRPE/81/Add.2 and in document WP.29/2020/120) with changes introduced into European legislation on RDE. This document is available with tracked changes in pdf version and docx format.

Proposal to amend Additive Deterioration factors in line with changes to corresponding regional provisions prompted by potential manipulation observed in the region and scheduled for introduction from October 2024.

Proposal to introduce provisions relating to

• Manipulation Devices and Strategies that were previously in the 09 series of amendments to UN R83,
• the levels to which certain provisions apply,
• clarifications and corrections to the requirements for the laboratory test for pure electric range ratio at low temperature for Pure Electric Vehicles
• an update to allow the use in Levels 1A and 2 of actual tyre rolling resistance values to calculate the final road load coefficient for the individual vehicles, and
• align the Regulation with the current regional status and the current state-of-the-art.
