Anotation

IEC 62391-2:2025 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. This edition includes the following significant technical changes with respect to the previous edition: 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. L’IEC 62391-2:2025 s’applique aux condensateurs electriques a double couche pour application de puissance. Les condensateurs electriques a double couche pour application de puissance sont destines aux applications qui exigent des courants de decharge dans la gamme des milliamperes aux amperes. Les caracteristiques des condensateurs incluent des performances comme une capacite relativement elevee et une faible resistance interne, ce qui concerne la classe 3 et a la classe 5 de la classification des mesures specifiee dans l’IEC 62391-1:2022. Le present document a pour objet de specifier les valeurs assignees et caracteristiques preferentielles, et de choisir, a partir de l’IEC 62391-1:2022, les procedures d’assurance de la qualite, essais et methodes de mesure appropries, et de donner les exigences de performances generales pour ce type de condensateur. Les severites d’essai et les exigences stipulees dans les specifications particulieres faisant reference au present document constituent des severites d’essai et des exigences specifiques, correspondant a un niveau de performances superieur ou egal. La definition de la densite de puissance et sa procedure de calcul peuvent etre consultees a l’Annexe A. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: a) la structure du document a ete integralement reetudiee afin de respecter les Directives ISO/IEC, Partie 2: b) introduction d’une nouvelle classification technique pour les methodes d’essai; c) reorganisation des methodes d’essai selon ces nouvelles categories; d) revision des tableaux, figures et references en fonction des modifications apportees.
