62. The representative of CLEPA recalled the purpose of document ECE/TRANS/WP.29/GRVA/2025/15 and presented (GRVA-23-41) a revised proposal focusing on the approval the dynamo function for e-trailers. GRVA agreed with the suggestion of the representative of Japan to document the GRVA understanding that e-trailers capable of self-propulsion should not be disguised ADS trucks without drivers; GRVA clarified that the e-trailer definition was in the Resolution R.E.3 supported that understanding.

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.
