Li-Ion, Ultra-capacitor Based Hybrid Energy Module

Abstract

Ultra-capacitors in multi kilo-farad ranges are now starting to be considered as alternatives or complimentary to batteries for products ranging from toys to hybrid vehicles as well as for space applications. Combining their superb specific power of 2-5kW/kg, high efficiency and very long cycle life with the high energy density of Li-Ion batteries, practical solutions to a variety of applications can be foreseen. To determine the optimum utilization of ultra-capacitors in applications where high power density and high energy density are required, an optimized Li-Ion/Ultra-capacitor Hybrid Energy Module (HEM) is presented in this paper. The optimized HEM takes into account both the power profile of the application and the power and energy densities of available energy and power devices. Finally, this paper presents a simulation and some experimental results.
