Secondary cells and batteries for renewable energy storage. General requirements and methods of test - On-grid applications1 Scope 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. 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
