Flow battery energy systems for stationary applications - Part 2-2: Safety requirements
IEC 62932-2-2:2020 applies to flow battery systems for stationary applications and their installations with a maximum voltage not exceeding 1 500 V DC in compliance with IEC 62932-1. This document defines the requirements and test methods for risk reduction and protection measures against significant hazards relevant to flow battery systems, to persons, property and the environment, or to a combination of them. This document is applicable to stationary flow battery systems intended for indoor and outdoor commercial and industrial use in non-hazardous (unclassified) areas. This document covers significant hazards, hazardous situations and events, with the exception of those associated with natural disaster, relevant to flow battery systems, when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse thereof. The requirements described in this document are not intended to constrain innovations. When considering fluids, materials, designs or constructions not specifically dealt with in this document, these alternatives are evaluated as to their ability to yield levels of safety equivalent to those specified in this document.
Flussbatterie-Systeme für stationäre Anwendungen – Teil 2-2: Sicherheitsanforderungen
Systèmes de production d’énergie de batteries d’accumulateurs à circulation d'électrolyte pour applications stationnaires – Partie 2-2: Exigences de sécurité
L’IEC 62932-2-2:2020 s’applique aux systèmes de batteries d’accumulateurs à circulation d’électrolyte pour les applications stationnaires et à leurs installations avec une tension maximale ne dépassant pas 1 500 V en courant continu conformément à l’IEC 62932-1. Le présent document définit les exigences et les méthodes d’essai pour la réduction du risque, ainsi que les mesures de protection contre les dangers significatifs, concernant les systèmes de batteries d’accumulateurs à circulation d’électrolyte, les personnes, les biens et l’environnement, ou une combinaison de ces facteurs. Le présent document est applicable aux systèmes de batteries d’accumulateurs à circulation d’électrolyte stationnaires destinés à une utilisation commerciale et industrielle à l’intérieur et à l’extérieur dans des emplacements (non classés) non dangereux. Le présent document couvre les dangers, ainsi que les situations et événements dangereux significatifs, à l’exception de ceux associés à une catastrophe naturelle, concernant les systèmes de batteries d’accumulateurs à circulation d’électrolyte, lorsqu’ils sont utilisés tel que prévu et dans les conditions prévues par le fabricant, y compris leur mauvaise utilisation raisonnablement prévisible. Les exigences décrites dans le présent document ne sont pas destinées à limiter les innovations. La prise en compte des fluides, matériaux, conceptions ou constructions dont le présent document ne traite pas particulièrement évalue ces variantes quant à leur capacité à produire des niveaux de sécurité équivalant à ceux spécifiés dans le présent document.
