Agenda Item 17.8.
Proposal for a draft UN GTR on in-vehicle battery durability for electrified heavy-duty vehicles

208. The representative of Canada, as technical sponsor to the IWG on EVE reminded that AC.3 gave its authorization to begin development of a new UN GTR on battery performance and durability of electrified heavy-duty vehicles at its last session. She also recalled the innovative and challenging nature of this activity, indicating that GTR 22 would be used as a framework, implying modifications to the framework developed for light duty vehicles, and in consideration of the unique attributes and characteristics of heavy duty vehicles.

209. Despite the amount of issues still to be resolved, she informed that the IWG on EVE was still hopeful to be able deliver according to the timeline set in the authorization.

210. The representative of China requested the IWG on EVE to consider the possibility to add chassis dynamometer as a possible solution to implement charge/discharge cycles for the batteries. He added that China stood ready to provide data and share the accumulated experience using chassis dynamometer to perform battery test cycles as well as on battery-swapping.

211. The representative of Canada thanked China for the feedback and offered to liaise with the members of the IWG on EVE for further exchanges on the topic.
