Supercapacitors offer distinct advantages over traditional batteries or other energy storage systems, such as high-power density and extended lifecycle. However, it is crucial to accurately model their behavior under various operating conditions, especially at high currents exceeding hundreds of amperes. This study explores the effectiveness of an equivalent model, previously introduced in the literature, but extends its testing range from 20 A up to the nominal current of the devices (140 A) in continuous mode. The tests are performed on large commercial supercapacitor cells contributing to a deeper understanding of supercapacitor performance in real-world scenarios.

Abstract
Supercapacitors offer distinct advantages over traditional batteries or other energy storage systems, such as high-power density and extended lifecycle. However, it is crucial to accurately model their behavior under various operating conditions, especially at high currents exceeding hundreds of amperes. This study explores the effectiveness of an equivalent model, previously introduced in the literature, but extends its testing range from 20 A up to the nominal current of the devices (140 A) in continuous mode. The tests are performed on large commercial supercapacitor cells contributing to a deeper understanding of supercapacitor performance in real-world scenarios.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
