電気二重層キャパシタの等価回路モデルとその応用

抄録

For a better understanding and detailed analysis of electric behavior of EDLC, we present one dynamic and two static equivalent circuit models each of which consists of a resistance and a capacitance varying with voltage. The differential capacity based dynamic model is used to simulate the discharge curve. Also the integral and effective capacity based static models are applied to estimate the energy efficiency and the constant current charge-discharge time. Owing to the energy oriented approach, the effective capacity based model shows its excellence in estimating efficiency and capacitance over the integral capacity based model.
