Batteries have been used as main energy storage devices in hybrid electric vehicles and portable electronics for many years and they are good in the medium-term low-power applications, but low dynamics and relatively shorter lifespan are their main week points. Due to their fast power response, high power density and high cycling capability, supercapacitors or double-layer capacitors are becoming...
The battery/supercapacitor hybrid energy storage system actively combines two energy storage devices to achieve better power and energy performances. This paper presents a detailed small-signal mathematical model that can represent the dynamics of the converter-interfaced energy storage system around the steady-state operating point. This model takes into account the effects on the currents of a variety...
Batteries are one of most cost-effective energy storage technologies. However, the use of batteries as energy buffers is somehow problematic, since it is hard, if not impossible, to recover from rapid power fluctuations without dramatically reducing the batteries' lifetimes. In a supercapacitor, energy storage is by means of static charge rather than of an electrochemical process as in a battery;...
The hybridization technique provides an effective approach to combining the best properties of a heterogeneous set of power sources to achieve higher energy density, power density and fuel efficiency. Hybrid power sources can be used to power hybrid electric vehicles using selected combinations of internal combustion engines, fuel cells, batteries, and/or supercapacitors. They can be deployed in all-electric...
