  1. Introduction


Section to be expanded based on comments from EVE IWG

The Executive Committee (AC.3) of the 1998 Agreement authorized the second mandate of the Electric Vehicles and the Environment Working Group at their November 2014 session. The full document is ECE/TRANS/WP.29/AC.3/401, and selected text from Part A of the EVE mandate is shown below, and follows up on work in the Electric Vehicle Regulatory Reference Guide (ECE/TRANS/WP.29/2014/81)2, often referred to elsewhere in this document as simply “the Guide.”



Therefore, a new mandate for the IWG on EVE (separate from the IWG on EVS) is desired to conduct additional research to address the recommendations outlined in Chapter 5 of the Guide and EV power determination:

Issues to be addressed in Parts A and B:

    1. Battery performance and durability (recommendation 5.3, ECE/TRANS/WP.29/2014/81);

    2. Determining the powertrain performance (maximum power and torque) of EVs).

Issues to be addressed only in Part A (information-sharing only):

    1. Method of stating energy consumption (recommendation 5.2, ECE/TRANS/WP.29/2014/81);

    2. Battery recycling/recyclability (recommendation 5.4, ECE/TRANS/WP.29/2014/81).

(iii) June 2016:

    1. IWG on EVE presents a first draft on the status of Part A and proposed gtr request(s) for Part B to GRPE;

    2. IWG on EVE presents informal documents on the status of Part A and proposed gtr request(s) for Part B for review by AC.3.”

Based on the mandate given to the group by AC.3, work was undertaken on the four topics mentioned. The results of the group’s work and their subsequent recommendations are shown in the sections below.
