GRVA-7 Discussion

64. The expert from France introduced ECE/TRANS/WP.29/GRVA/2020/20, aimed at clarifying the provisions in Annex 3, para. 1.5.3.1., in case the batteries have been recharged or replaced with a charged set, between the hot performance and recovery procedure, when the linings temperature is no longer at the temperature. GRVA adopted it and requested the secretariat to submit it as supplement to the 01 series of amendments to UN Regulation No. 13-H for consideration and vote by WP.29 and AC.1 at their March 2021 sessions.

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.
