Secondary cells and batteries containing alkaline or other non-acid electrolytes - Secondary lithium cells and batteries for use in industrial applications

IEC 62620:2014 specifies marking, tests and requirements for lithium secondary cells and batteries used in industrial applications including stationary applications. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, the former takes precedence. (e.g. IEC 62660 series on road vehicles). The following are some examples of applications that utilize the cells and batteries under the scope of this standard. - Stationary applications: telecom, uninterruptible power supplies (UPS), electrical energy storage system, utility switching, emergency power and similar applications. - Motive applications: fork-lift truck, golf cart, AGV, railway, and marine, excluding road vehicles. This standard applies to cells and batteries. If the battery is divided into smaller units, the smaller unit can be tested as the representative of the battery. The manufacturer clearly declares the tested unit. The manufacturer may add functions, which are present in the final battery, to the tested unit.

Accumulateurs alcalins et autres accumulateurs à électrolyte non acide - Éléments et batteries d'accumulateurs au lithium pour utilisation dans les applications industrielles

L'IEC 62620:2014 spécifie le marquage, les essais et les exigences pour les éléments et les batteries d accumulateurs au lithium utilisés dans les applications industrielles, y compris les applications stationnaires. En cas d'existence d'une norme IEC spécifiant des conditions d'essai et des exigences pour des éléments destinés à des applications particulières, et qui serait en contradiction avec la présente norme, la publication particulière est appliquée en priorité (par exemple, la série IEC 62660 sur les véhicules routiers). Ci-après figurent des exemples d'applications utilisant les éléments et les batteries inclus dans le domaine d'application de la présente norme. - Applications stationnaires: télécommunications, alimentation sans interruption (ASI), système de stockage de l'énergie électrique, sélecteur de service, alimentation d'urgence et applications analogues. - Applications mobiles: chariot élévateur, voiturette de golf, AGV, ferroviaire, et marine, à l'exception des véhicules routiers. La présente norme s'applique aux éléments et aux batteries. Si la batterie est divisée en unités plus petites, l'unité plus petite peut être soumise aux essais pour représenter l'ensemble de la batterie. Le fabricant déclare clairement l'unité soumise aux essais. Le fabricant peut ajouter des fonctions, qui sont présentes dans la batterie finale, à l'unité soumise aux essais.

Sekundarni členi in baterije z alkalnimi ali drugimi nekislinskimi elektroliti - Sekundarni litijevi členi in baterije za industrijsko uporabo (IEC 62620:2014)

Ta mednarodni standard določa označevanje, preskuse in zahteve za sekundarne litijeve člene in baterije za industrijsko rabo, vključno s stacionarno uporabo. Če obstaja standard IEC, ki določa preskusne pogoje in zahteve za člene za posebno uporabo ter je v nasprotju s tem standardom, ima prednost prvi. (npr. skupina standardov IEC 62660 o cestnih vozilih).
Spodaj je naštetih nekaj primerov uporabe členov in baterij v okviru tega standarda.
• Stacionarna uporaba: telekomunikacije, napajalniki za neprekinjeno napajanje (UPS), sistem za shranjevanje električne energije, preklapljanje storitev, zasilno napajanje in podobne uporabe.
• Pogonska uporaba: viličar, voziček za golf, AGV; železnica in pomorstvo, brez cestnih vozil.
Ker ta standard zajema baterije za različno industrijsko uporabo, vključuje skupne in minimalne zahteve za različno uporabo.
Ta standard velja za člene in baterije. Če je baterija razdeljena na manjše enote, je mogoče manjšo enoto preskusiti kot reprezentativno za baterijo. Proizvajalec jasno navaja preskušeno enoto. Proizvajalec lahko preskušeni enoti doda funkcije, ki jih vsebuje končna baterija.
