Wiederaufladbare Zellen und Batterien für die Speicherung erneuerbarer Energien - Allgemeine Anforderungen und Prüfverfahren - Teil 2: Netzintegrierte Anwendungen (IEC 61427-2:2015 + AMD1:2024); Deutsche Fassung EN 61427-2:2015 + A1:2024
Overview
This part of IEC 61427 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. Related power conversion and interface equipment is not covered by this part of IEC 61427. The standard differs from DIN EN 61427-2 (VDE 0510-41):2016-09 as follows: a) references to Annex B have been added in Chapter 6; b) Annex B has been newly added. 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 grid's performance when randomly major amounts of electrical energy from renewable energy sources are fed into it.
