Huawei Montevideo supercapacitor model

Why is supercapacitor a hot research direction of energy storage technology?

Abstract: With the development of energy storage technology, new types of electrical energy storage components have received extensive attention. Among them, supercapacitor has become a hot research direction of energy storage technology because of its advantages such as high-power density, fast charging and discharging, long cycle life and so on.

How to improve power management during use of a supercapacitor?

Various means to follow the online dynamics and improve power management during use of the supercapacitor may involve real time equivalent circuit parameter estimation , Kalman filtering , , and variable capacitor models to allow better online power management.

Can a supercapacitor model be used for energy storage?

The simulation results have verified that the proposed model can be applied to simulate the behaviour of the supercapacitor in most energy and power applications for a short time of energy storage. A supercapacitor test circuit is given to test the charge and discharge of supercapacitor modules.

How to model a supercapacitor?

Here, it is shown that consistent modelling of a supercapacitor can be done in a straightforward manner by introducing a dynamic equivalent circuit model that naturally allows a large number or a continuous distribution of time constants, both in time and frequency domains.
