Super-capacitor integration into hybrid vehicle power source

Abstract

The plug-in hybrid vehicle based on the concept of battery operated vehicle with strong electrical motor(s) and electrochemical battery is for thermal comfort of crew and for occasional elongated travel range completed by generator, which is designed on average traction power only and during of journey is mainly used in co-generative run for cabin heating. Such vehicle efficiency can be improved by the third power source, specifically used only for acceleration and regenerative braking purposes. That role is optimal for super-capacitor, which has very good charging efficiency and can store the energy from braking to the next acceleration. Both these actions are usually very fast with high power in very short time. Its sizing and voltage control is investigated in this paper.
