158. The representative of Canada, on behalf of the secretariat of the IWG on EVE, said that, following the authorization to develop a UN GTR granted by AC.3, Heavy-duty in-vehicle battery durability was the most significant work being performed by the IWG on EVE.

159. He reminded that there were no existing UN GTR’s where the in-vehicle battery durability was considered for classes of HDVs and the IWG on EVE was trying to develop a new UN GTR to resolve this, using a similar framework as UN GTR No. 22 applied for Light-Duty Vehicles (LDVs). He further informed that there was limited technical similarity between light- and heavy-duty test procedures.

160. He elaborated that due to the variety and unique use cases of HDVs, the development was proving to be challenging and some necessary modifications needed to be made to the framework, in consideration of these unique sector attributes and vehicle characteristics. He mentioned more time would be requested to submit a final proposal at the October 2024 session of GRPE, with a potential consideration by AC.3 at its March 2025 session.
