Draft minutes of the 13th IWG on EV/HFCV-RS meeting held 8 October 2026. The group reviewed the work program ahead of the forthcoming GRPE session scheduled for 14-16 October 2026, with the objective to provide GRPE with a first draft of the future UN Regulation. The latest draft Regulation was jointly reviewed, continuing technical discussions on provisions and addressing comments and proposals from stakeholders. Particular attention was given to the scope, type definition and testing requirements, and the presence of installer definition in the UN Regulation. Participants worked collaboratively towards consolidating inputs and preparing an agreed version of the draft for presentation at the next GRPE session.
Proposal to introduce UBEcertified in templates for the information document and WLTP test report, clarify that test results must be within 2 percent of the declared value, and specify the number of significant figures to be used for Usable Battery Energy of the vehicle at certification as related to level 1A requirements in Annex A1 and Annex A2 to UN R154.
Document outlines preparation for establishing a Task Force on Swappable Battery under GRPE. Identifies sustainability aspects including on-board battery use as renewable energy buffer, battery cost and separate sale/lease models, vehicle lifespan exceeding battery life requiring service exchange, and battery replacement due to technology evolution. Lists issues for WP.29 framework covering vehicle approval with different battery pack numbers, separate battery approval, safety measures during swapping, attachment functionality, durability requirements, battery history tracing, cyber security, battery failure alerts, software updates, battery lifetime definition, and compatibility checking between battery and vehicle combinations. Proposes establishment of new Task Force under GRPE with collaboration among existing groups, two-step approach for identifying work items and drafting Terms of Reference, and timeline for five Task Force meetings from December 2026 to April 2027.
Proposal to revise the generic transfer function coefficient based on 2026 test campaign results, revise the ALI range for specific transfer function assessment, integrate assessment criteria for both test methods, and delete the coefficient of determination (R²) requirement since delta ALI and RMSE are sufficiently tight for assessment.
The document describes an ACPE system for judging pedal misapplication from driver accelerator pedal operation and vehicle motion without object detection sensors, and suppresses sudden acceleration. The system performs pedal error checks to determine whether sudden accelerator operation may be pedal misapplication, non-operation checks to verify whether the scene involves intended acceleration, and suppresses acceleration if steps determine pedal error. The system does not activate during intended acceleration in hard-to-distinguish scenes including turning, changing lanes, starting at stop signs or signal lights, and steep uphill driving. False positive activation depends on driver maneuver; measures applied in Japan include offering the system as an option, restricting access to dedicated key users only, and explaining possible false positive activation at point of sale.
The IWG on ACPE shall review UN Regulations on ACPE, modify them if necessary, add provisions for a new draft UN GTR on ACPE, and prepare a draft UN GTR on ACPE for submission to GRVA for adoption. The text shall be performance based and technology neutral. The IWG will be managed by three Co-Chairs (Japan, Germany, and Canada) and a Secretary (OICA), report to GRVA, remain open to all WP.29 participants, conduct work in English, and reach decisions by consensus. The IWG will deliver a new UN GTR on ACPE for the September 2028 session of GRVA, with adoption expected at WP.29’s 206th session in March 2029.
The agenda includes discussion of research outcomes and possible conclusions, other business, and list of action items and next meetings. The next meeting is scheduled for 12-14 January 2027 in Japan with 15 January 2027 for leadership to prepare report for GRVA.
