World Forum for the Harmonization of Vehicle Regulations | Session 178 | 24-28 Jun 2019
Geneva
Agenda Item 19.23.
Draft UN GTR on determination of electrified vehicle power (Electric vehicles and the environment)

181. The representative from Canada, on behalf of the leaders of IWG on Electric Vehicle and the Environment (EVE) provided an update on recent activities. Two meetings of the IWG on EVE had been held since the last WP.29 session. The first was a 3-day meeting in Stockholm in April of 2019, including a full-day drafting session for the subgroup on system power determination. He thanked the Swedish government for hosting the meeting. The second was a half-day meeting in May 2019 in Geneva, along with a separate half-day drafting session for the subgroup on system power determination.

182. He reported that the IWG on EVE had performed a first round of validation testing throughout 2018 for the development of a UN GTR on Determination of Electrified Vehicle Power (DEVP). Some discrepancies between the results from two test methods were identified. IWG on EVE believed it had identified solutions to address issues with the first draft test procedure, and a second phase of validation testing was currently underway and expected to be completed in the fall of 2019. In May 2019, the GRPE endorsed a plan to complete a final UN GTR proposal for approval by AC.3 in November 2020, which was a one-year delay from the original target timelines of EVE. An updated working document outlining these revised timelines for completion of the UN GTR was to be submitted to AC.3 in November 2019 to revise ECE/TRANS/WP.29/AC.3/53.

183. He informed the session that efforts to model Electric Vehicle (EV) battery durability were led by the European Union and validated using long-term EV testing results from Canada. At GRPE in May 2019, IWG on EVE noted that a UN GTR on in-vehicle battery durability for EVs could be developed that would incorporate the concepts of battery life modelling, deterioration factors and in-service conformity checks. He highlighted IWG on EVE would further refine its views on a possible UN GTR over the coming months and present a proposal to GRPE for in-vehicle battery durability for EVs in January 2020.

184. He mentioned that interactions with other bodies within the ECE framework on the development of a method of stating energy consumption were led by the Secretary of GRPE. Interest had emerged from the Group of Experts on Energy Efficiency (GEEE) of the Sustainable Energy Division of ECE to assume leadership of this work, and IWG on EVE would continue to follow updates on this group and provide assistance and/or support if necessary.

185. He announced that the next meetings of EVE IWG would be a three-day working group and drafting group meeting in Brussels in October 2019, and a half-day session in conjunction with GRPE in January 2020.
