Overview

This part of IEC 62391 applies to electric double-layer capacitors for power application. Electric double-layer capacitors for power are intended for applications that require discharge currents in the range from mA to A. The characteristics of the capacitors include such performance as relatively high capacitance and low internal resistance, which is applicable to Class 3 and Class 5 of the measurement classification specified in IEC 62391-1:2022. The object of this document is to specify preferred ratings and characteristics and to select from IEC 62391-1:2022 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of capacitor. Test severities and requirements specified in detail specifications referring to this document provide specific test severities and requirements of an equal or higher performance level. The definition of power density and its calculating procedure can be found in Annex A. The standard differs from DIN EN 62391-2:2007-02 as follows: a) the document has been completely restructured to comply with the ISO/IEC Directives, Part 2; b) introduction of a new technical categorization for the test methods; c) reorganization of the test methods have been according to these new categories; d) revision of the tables, figures and references according to changes. Application of this document increases investment security for manufacturers and users, provides testing laboratories and manufacturers with defined information for testing, and enhances product compatibility between manufacturers.
