65. The expert from CLEPA presented GRVA-07-68, introducing ECE/TRANS/WP.29/GRVA/2020/21 with provisions for the type approval of Electromechanical Braking systems. The expert from OICA introduced GRVA-07-46, aimed at improving and finalizing some open items in the CLEPA proposal. The expert from the Netherlands stated that some open items should still be finalized before adoption, such as para. 5.1.1.2. and should address the deterioration over time of the state of charge and the state of health. He also mentioned issues related to temperature differences during a trip that might impact the performance of the system. GRVA agreed to resume consideration of this matter at its next session.

GRVA agreed to resume consideration of this agenda item dealing with Electro-Mechanical Brakes at its September 2021 session.

98. The expert from CLEPA presented GRVA-09-06, introducing ECE/TRANS/WP.29/GRVA/2020/21, as amended by GRVA-09-05, providing provisions for the type approval of trucks equipped with electromechanical brakes. He clarified that no trailer with electromechanical brakes was considered in the proposal. He explained the benefits of such system for hybrid electric and electric vehicles. He acknowledged that further work was needed to develop Periodic Technical Inspection and electric storage devices requirements.

99. GRVA agreed to review a revised proposal based on GRVA-09-05, as formal document, at its next session.

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.
