Proposal to establish definitions for “e-axle”, “e-axle trailer” and “dynamo function” and to establish provisions for the approval of e-axle trailers with regard to their “dynamo function”.
76. GRVA recalled the purpose of ECE/TRANS/WP.29/GRVA/2025/15 introducing provisions for the approval of e-axles. The representative of CLEPA, also on behalf of CLCCR and OICA, presented (GRVA-24-39) the ongoing discussions held at meetings of the e-trailer industry group, working in two phases. He recalled that Phase I was completed (dynamo function) and was tabled for adoption by WP.29 in March 2026. He detailed the activities on Phase II on e-trailers that recuperates and supports propulsion or other trailer systems. He detailed the timeline, which is interdependent with the timeline of the January 2027 edition of ISO 11992 (as the 2023 edition was deemed unsafe to implement). He recalled the provisions in UN Regulation No. 100 (Electric power trained vehicles) already adopted and in force since October 2025. He listed some technical aspects under discussion and announced two workshops scheduled in spring 2026. The representative of Sweden recommended to keep this workstream aligned with the trailer definition in the Consolidated Resolution R.E.3.
