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.
