IEC 61427-2 NWP

This International Standard relates to secondary batteries used in Electrical Energy Storage (EES) applications, and the associated methods of test, which are proposed for the verification of their safe operation, performance and endurance. 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 so to stabilize the grid’s performance. This standard, part 2 of the 61427 series, deals with batteries used in on-grid applications and is essentially battery chemistry neutral (agnostic). Related power conversion and interface equipment is not covered by this standard.
