111. The expert from CLEPA presented GRVA-15-49, informing GRVA on their activities related to drafting provisions for the approval of Electro-Mechanical Brakes (EMB). He mentioned GRVA-15-17, reflecting the current status of their work on the development of an amendment to UN Regulation No. 13.

112. The expert from the United Kingdom of Great Britain and Northern Ireland supported the principle of developing regulatory provisions to bring this technology on the market. He called for more transparency on similar activities for passenger cars and UN Regulation No. 13-H.

113. The expert from CLEPA mentioned OICA’s involvement in these activities. He added that similar activities for passenger cars were indeed in preparation, that exchanges among stakeholders existed to keep definitions aligned. He explained that the systems layout could differ between light and heavy vehicles. He highlighted the complexity of UN Regulation No. 13 compared to UN Regulation No. 13-H.

114. The expert from Germany welcomed the activities and noted the high frequency of meetings on that topic. He suggested that GRVA organize a workshop to review the activities and update the contracting parties not yet involved. The experts from Czech Republic, Denmark, Netherlands and United Kingdom of Great Britain and Northern Ireland expressed interest for such a workshop. The expert from Japan suggested the workshop to be organized as an informal and hybrid meeting.

115. GRVA noted the activities of the Working Party on Pollution and Energy (GRPE) regarding battery durability. GRVA agreed to host an informal workshop on EMB open to all GRVA stakeholders, including contracting parties to the 1958 and 1998 Agreements.

96. The expert from CLEPA updated GRVA (GRVA-14-52) on the outcome achieved following the weekly meetings organized by CLEPA since February 2022, with both industry group representatives and contracting parties regarding the drafting of provisions for the approval of Electromechanical Brakes (EMB) for electric powered trucks and coaches. EMB was presented for the first time to GRVA at the seventh session of GRVA (see ECE/TRANS/WP.29/GRVA/2020/21). The original proposal has been iteratively updated following GRVA guidance (see ECE/TRANS/WP.29/GRVA/2021/24, ECE/TRANS/WP.29/GRVA/2022/8 and GRVA-13-05). He presented the recent developments related to the effect of aging of the electrical energy storage device. He presented GRVA-14-12, the most recent draft superseding GRVA-13-05. He kindly invited interested contracting parties to join their activities.

97. GRVA noted the presentation of the expert from CLEPA on EMB and their ambition to submit an amendment proposal to UN Regulation No. 13, based on GRVA-14-12, for consideration at the next session.
