Szukana fraza: [Abstrakt = "The most important element of today modern energy systems, backup power, electric vehicles and energy recovery systems are supercapacitors. For the purpose of their proper operation, diagnostics and control are required to know the parameters of their mathematical models. The specific properties of the materials and the applied solutions make the best model to describe the relationship between current and voltage at the terminals of the supercapacitor as the fractional order differentiation. This approach will simplify the structure of the model, while providing a very good estimation of unknown parameters. The paper present the results of the estimation of the order of the derivative model for 1200F supercapacitor, for different values of the currents charging and discharging. It describes the structure and properties of the measurement system and implemented specific test algorithm."]
