Effects of an Ultra-Capacitor and Battery Energy Storage System in a Hybrid Electric Vehicle

This paper focuses on the effects of ultra-capacitors as a component of energy storage in hybrid electric vehicles (HEV). The main energy source in a hybrid vehicle is the battery. HEVs with battery sources are presently fairly effective; however, major drawbacks include the cost and size of such batteries. The purpose of this paper is to demonstrate that the addition of ultra-capacitors as a component of the energy storage system can reduce …
