This document addresses open issues regarding the Fast Charge Power Curve Resolution draft still under technical discussion where no consensus has been reached by the F&SC Cluster at submission of ECE/TRANS/WP.29/GRPE/2026/52. Open points cover measurement system requirements, test vehicle conditions, test preparation, vehicle preparation phase, parameter definitions, test evaluation tolerance criteria, and data processing and calculation of KPIs including maximum charging power, average charging power in 10–80% SoE range, power curve from 10% SoE to full charge, charging duration, and recharged energy or range in 10 minutes.

Terms of Reference for the UNECE EV fast- & smart-charging cluster, a joint activity of WP.5 e-mobility Task Force and the IWG on EVE. The cluster aims to promote user-friendly, safe and scalable adoption of fast and smart charging functionalities of electric vehicles and their integration in the energy system. Task A develops a new WP.29 resolution on DC Fast Charge Power Curve (FCPC) of electric vehicles in three phases: Phase 1 establishes a harmonized test procedure for light duty vehicles; Phase 2 develops requirements for consumer information and minimum performance requirements; Phase 3 investigates expansion to heavy duty applications. Task B inventories the need for harmonization of other recharging capabilities and recharging documentation, including collecting existing international standards and initiatives, identifying discrepancies and gaps, and issuing a harmonized standardization/regulatory roadmap for smart and bi-directional charging of EVs by vehicle category. Chairmanship is held by The Netherlands from January 2025 to October 2027.

Proposal to replace Annex 1 with revised engine and vehicle characteristics and information concerning the conduct of tests. The new annex specifies requirements for supplying information in triplicate, including details on general vehicle identification, masses and dimensions, energy converters and power plant description, transmission, suspension, and tyres and wheels, along with associated footnotes defining terms and providing technical specifications.

Proposal to amend para. 2.11.1.2.2. in annex B6 of the original series to correct typos, amend para. 4.4.6.2. in annex B8 of the original series to correct notation, and add footnotes below Table 3b in para. 6.7.2. of the 01 series regarding fuel types and vehicle specifications, aligned with the 03 series.

Proposal to amend Appendix 2, paragraph 2.1. in the 02 series and paragraph 2.1.2. in the 01 and 03 series to correct typographical errors introduced in the French versions of WP.29/2025/100, WP.29/2025/101 and WP.29/2025/102.

Proposal to amend para. 9.3.2.1 in annex 4 to correct a paragraph number reference from ‘9.2.3.7.’ to ‘9.3.2.7.’ in the text describing measurement principles. The correction addresses a typographical error introduced in WP.29/2025/94.

This document presents a comprehensive technical roadmap on smart and bidirectional charging for electric vehicles. It reviews standards governing interfaces between vehicles, electric vehicle supply equipment and electricity grids; identifies remaining gaps in standardisation, certification and testing; and recommends actions for global harmonisation. The roadmap focuses on light-duty vehicle categories (M₁, M₂ ≤5 t and N₁), covers communication protocols including ISO 15118-20 and Amendment 1, grid codes across multiple regions, and battery data identifiers under UN GTR No. 22. Key findings include: proprietary solutions and vendor lock-in remain prevalent; ISO 15118-20 has not yet achieved broad interoperability in practice; grid-code conformance regimes for AC bidirectional charging lack mature certification pathways; and end-to-end conformance testing remains immature in major regions. Main recommendations include establishing a Global Task Force on Bidirectional EV Charging, clarifying capability communication, ensuring regulations track standards evolution, extending electromagnetic compatibility requirements to partial-load operation, and maintaining consistency between automotive and energy-sector cybersecurity requirements.

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

Industry guidelines developed jointly by CLEPA and OICA to provide a harmonised methodology for determining the carbon footprint of passenger cars through their full life cycle, from material extraction through production, use, and end-of-life. The guidelines establish four levels of assessment based on data granularity and intended application (ranging from public policy analysis to detailed supply-chain reporting), with fixed methodological approaches for Levels 3 and 4. They specify treatment of GHG emissions including biogenic carbon, land use change, and fossil emissions; define data quality requirements including primary data collection and allocation procedures; and establish system boundaries across material production, parts and vehicle assembly, use, and end-of-life stages, employing the Circular Footprint Formula for material recycling assessment.

UN Regulation No. 168 includes two versions of the manufacturer’s information document; Part 1 applies when all vehicles covered are also type-approved according to UN Regulation No. 154, while Part 2 applies when at least one vehicle is not covered by UN Regulation No. 154 type-approval.

Joint OICA and CLEPA workgroup presentation on industry guidelines for life cycle assessment of passenger cars and parts. The guidelines establish a common global methodology for LCA data exchange along the supply chain, independent of regulatory development. Key technical points include defining functional units for passenger cars and a declared unit for parts, specifying primary and secondary data requirements, addressing chain of custody through aligned models and mass balance approaches, allowing mixed energy modelling approaches with market-based modelling for decarbonisation efforts, introducing representative vehicles for full vehicle LCA reporting, and introducing representative parts to simplify supplier reporting to OEMs.

Proposal to amend para. A.1.3.2.1. to modify the PEMS consistency check of exhaust mass flow and gas concentrations for fuels with a molar carbon to hydrogen ratio of 0. For such fuels, the formula in para. 8.4.1.6. of Annex 4 shall be used instead, with Equations 30 and 31 applied for Type 1A dual-fuel hydrogen engines. The verification shall not apply to engines operated on non-carbon fuels or dual-fuel engines when operated in dual-fuel mode with at least one fuel having a molar carbon to hydrogen ratio of 0.

A presentation on industrial retrofit as a transition solution for decarbonizing the existing vehicle fleet. Industrial solutions are available and scaling up, but lack of harmonized regulatory requirements is hindering deployment. Differences in national regulatory frameworks directly affect retrofit sector development across countries. Testing at vehicle level is necessary to account for retrofit system impacts. A forthcoming UNECE Regulation should provide a clear approval framework, establish a streamlined approval process, and ensure mutual recognition of approvals granted by Contracting Parties.
