Electrical energy storage (EES) systems - Part 5-3: Safety requirements for grid-integrated EES systems – Performing unplanned modification of electrochemical based system
IEC 62933-5-3:2023 applies to those instances when a BESS undergoes unplanned modifications. Such modifications can involve one or more of the following: - changes in energy storage capacity; - changes of chemistries, design and manufacturer of the accumulation subsystem; - changes of a subsystem component using non-OEM parts, - changes to the mode of operation, - changes of the installation site, or - changes in an accumulation subsystem due to an installation of reused or repurposed batteries. Any such modification can impair the original state of safety of the BESS. This document complements IEC 62933-5-2, which relates to the overall safety aspects of a BESS. The requirements covered by this document are applied in addition to the requirements in IEC 62933-5-2 in accordance with each situation.
Systèmes de stockage de l’énergie électrique (EES) - Partie 5-3: Exigences de sécurité pour les systèmes EES intégrés dans un réseau – Modification non programmée d'un système électrochimique
L’IEC 62933-5-3:2023 s’applique aux situations dans lesquelles un BESS subit des modifications non programmées. Ces modifications peuvent comporter un ou plusieurs des éléments suivants: - modifications de la capacité de stockage énergétique; - modifications des compositions chimiques et de la conception, et changement de fabricant du sous-système d’accumulation; - modifications d’un composant de sous-système qui utilise des pièces non OEM; - modifications du mode de fonctionnement; - modifications du site d’installation; ou - modifications d’un sous-système d’accumulation en raison d’une installation de batteries réutilisées ou réaffectées. Une telle modification peut compromettre l’état de sécurité initial du BESS. Le présent document complète l’IEC 62933-5-2 qui concerne les aspects liés à la sécurité globale d’un BESS. Les exigences couvertes par le présent document sont appliquées en plus des exigences de l’IEC 62933-5-2 conformément à chaque situation.
