48. The expert from IMMA introduced a presentation (GRSP-68-22) about the need of dedicated requirements for swappable Rechargeable Electric Energy Storage Systems (REESS). He clarified that swappable REESS might be mounted in different vehicle models, having different mounting positions. He added that to ensure safe operation of a swappable REESS in different orientations and avoid multiple testing for each vehicle design he would propose to introduce dedicated stricter testing conditions into the UN Regulation. GRSP agreed to resume discussion on this subject on the basis of a possible proposal from IMMA.
