Secondary cells and batteries for renewable energy storage - General requirements and methods of test - Part 2: On-grid applications
IEC 61427-2:2015 relates to secondary batteries used in on-grid Electrical Energy Storage (EES) applications and provides the associated methods of test for the verification of their endurance, properties and electrical performance in such applications. The test methods are essentially battery chemistry neutral, i.e. applicable to all secondary battery types. On-grid applications are characterized by the fact that batteries are connected, via power conversion devices, to a regional or nation- or continent-wide electricity grid and act as instantaneous energy sources and sinks to stabilize the grids performance when randomly major amounts of electrical energy from renewable energy sources are fed into it. Related power conversion and interface equipment is not covered by this part of IEC 61427.

Accumulateurs pour le stockage de l'énergie renouvelable - Exigences générales et méthodes d'essais - Partie 2: Applications en réseaux
L'IEC 61427-2:2015 porte sur les batteries d'accumulateurs utilisées dans les applications de stockage de l'énergie électrique (EES) en réseau et définit les méthodes d'essai associées pour la vérification de leur endurance, de leurs propriétés et des performances électriques dans une telle application. Les méthodes d'essai sont indépendants de la chimie de la batterie, c'est-à-dire applicables à tout type de batterie d'accumulateurs. Les applications en réseau sont caractérisées par le fait que les batteries sont connectées, via des dispositifs de conversion d'énergie, à un réseau d'électricité régional, national ou continental et font office de sources ou de réservoir d'énergie instantanées pour stabiliser les performances du réseau électrique lorsque de grandes quantités d'énergie électrique provenant de sources d'énergie renouvelables sont introduites aléatoirement dans celui-ci. Les équipements de conversion d'énergie et d'interface associés ne sont pas couverts par la présente partie de l'IEC 61427.
Sekundarni členi in baterije za shranjevanje obnovljive energije - Splošne zahteve in preskusne metode - 2. del: Omrežne izvedbe
Ta del standarda IEC 61427 se navezuje na sekundarne baterije, ki se uporabljajo v omrežnih izvedbah za shranjevanje električne energije (EES), ter navaja povezane preskusne metode za preverjanje njihove vzdržljivosti, lastnosti in električnih zmogljivosti v teh izvedbah. Preskusne metode so v osnovi baterijsko kemično nevtralne, tj. uporabljajo se za vse vrste sekundarnih baterij. Za omrežne izvedbe je značilno, da so baterije povezane s področnim, državnim ali kontinentalnim električnim omrežjem ter delujejo kot viri takojšnje energije in korita za stabilizacijo učinkovitosti omrežja, ko se iz virov obnovljive energije v omrežje dovajajo naključno velike količine električne energije. Ta del standarda IEC 61427 ne vključuje povezane opreme za pretvorbo energije in vmesniške opreme.
