Proposal for a new UN GTR on the determination of system power of hybrid electric vehicles and of pure electric vehicles having more than one electric machine for propulsion -Determination of Electrified Vehicle Power (DEVP)
48. The representative from the United States, drafting coordinator for the proposed new UN GTR, presented GRPE-81-33 as a brief introduction to ECE/TRANS/WP.29/GRPE/2020/12, as amended by GRPE-81-27 on a proposal for a new UN GTR on DEVP. The representative from the Netherlands requested if there was any evidence on the equivalence between Test Procedure 1 (TP1) and Test Procedure 1 (TP2), as described in the proposal. The drafting coordinator of the proposal highlighted tests performed by the Joint Research Centre of the EC on vehicles where both TP1 and TP2 test could be performed. He emphasized the test results were closely related and finally added that in the majority of hybrid vehicle architecture, only one of the test procedure can be performed, depending on software/hardware configurations.
49. The representative from OICA asked how family concepts was being tackled in the proposal, especially thinking about which and how many vehicles should be tested when approaching type approval authorities. The drafting coordinator acknowledged the issue had been raised and that final solutions were still being considered; he wondered if other family concepts from other legislative texts (for example using WLTP family concepts) could be used when applying the proposed UN GTR requirement as part of other regulatory needs. The Chair of GRPE reminded GRPE that UN GTRs are not related to type approval and the relating administrative provisions, and that the proposed UN GTR on DEVP would still need to be transposed into the 1958 Agreement, for example as part of UN Regulation No. 154 on WLTP or UN Regulation No. 85. He proposed to have such discussion during forthcoming sessions of GRPE.
50. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/12 and GRPE-81-27 as amended by Addendum 4 to this chair’s notes, as draft new UN GTR No. [XX] on DEVP, together with Annex VII as its technical report that will be extracted from the adopted documents, as proposed by the secretariat. GRPE requested the secretariat to submit Addendum 4 and Annex VII to WP.29 and AC.3 for consideration and vote at their November 2020 sessions as draft new Un GTR No. [XX] on DEVP.
