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.
The supercapacitor supplies or absorbs the large current pulses that occur during engine starting or regenerative braking, improving the transient response and efficiency of the battery supply. In this report, two supercapacitor models are pre- sented.
The supercapacitor model is simulated in this study by using MATLAB/Simulink, and the efficiency of the model is improved by verifying and evaluating the parameters. Also, its parameters are tuned in such a way that a satisfiable efficient output is obtained.
In Ref. , the model of the supercapacitor is first developed and identified using the RLS algorithm. The model is then used together with the EKF algorithm to estimate the SoC. Finally, based on the static limits for the current, charge/discharge cut-off voltages, and SoC constraints, the power availability is estimated.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
