Study of Supercapacitor Parameters and Characteristics
ABSTRACT
The paper [11] shows that the supercapacitor is a high efficient and
green energy storage component that offers intensive charging and dis-
charging current and performs a perfect reliability and cycling abil-
ity. In this paper three topics are discussed for supercapacitor-based
system research and application. Firstly, a comparison among sev-
eral parameter models of the supercapacitor is presented. In the same
time the characteristics of ESR (Equivalent Series Resistance) and EPR
(Equivalent Parallel Resistance) are described and studied. Secondly
the methods of voltage sharing and overvoltage protection for series
connected supercapacitors are discussed, and their advantages and dis-
advantages are compared with each other. Thirdly a radiation experi-
ment is taken to examine the supercapacitor in its anti-radiation ability
for spaceflight application.
