Study on the dynamical characters of supercapacitor terminal voltage

Supercapacitor large current charge-discharge experiments were done to research the undulatory phenomenon of storage energy and voltage across circuit. The effect of charge-discharge current and equivalent serial resistance on dynamical characters of voltage was expatiated.A predicting model with logarithm function of voltage to estimate roughly supercapacitor storage energy was set up to guide simulation,design and optimization of energy management system with supercapacitor in pure electric and hybrid electric vehicles.
