DESIGN OF SUPER CAPACITOR WITH TEMPERATURE EFFECTS USING A CONSTANT VOLTAGE SOURCE

Abstract

Super capacitor have lower energy storage but higher power exchanging capability compared to batteries. This paper examines the temperature effects on an super capacitors using a constant voltage source. In new power application, it is very important to understand how super capacitor will perform in various temperatures and charging and discharging methods. By knowing the super capacitor behaviour, system can be optimized for efficiency and minimize internal circuit losses. The performance and lifetime of an ultra capacitor are temperature dependent. The objective of this paper is to develop necessary modelling and simulation tools for evaluating the temperature dependence of ESR in a constant voltage charge and discharge cycle.
