Design and Characterization of an Actively Controlled Hybrid Energy Storage Module for High-Rate Directed Energy Applications

ABSTRACT:

There's considerable want for a mobile, reliable, economical, and compact prime power offer for a bunch of applications, including directed energy and electrical grid backup among others. Electrochemical energy storage devices, which possess either high-power density or high-energy density, have been developed recently and are very applicable to be used in these applications. The need for both high energy and high power, however, makes the look and implementation of such a first-rate power supply a nontrivial task. Whereas lithium-ion batteries (LIBs) are on the market, which possess both high power and energy density, operation at high power reduces their cycle life, decreasing the reliability and increasing the value of the system when replacement becomes necessary a lot of frequently. One proposed method involves optimally combining high-energy batteries with high-power electric double layer capacitors (EDLCs) using actively controlled Power Electronics to control this to and from every respective device. In such a theme, energy will be slowly sourced to and from the batteries, while the capacitors are used to provide or settle for the majority of the current when the demand is high, particularly during fast transients. This kind of scheme ought to not solely maximize the batteries’ cycle life and guarantee that both the energy and power needed of the load(s) is always available, but can conjointly increase the instantaneous power capabilities of the system, offering a well-rounded solution to sourcing steady and/or transient masses. When augmenting a fossil fuel generator with a hybrid energy storage module (HESM), the HESM has the power to act as a high-energy reservoir that may harvest energy from the generator when the hundreds are in brief periods of inactivity. This enables the generator to be continuously base loaded, thereby maintaining a high level of potency in any respect times, while theoretically maintaining the desired power quality of the most ac bus. At the University of Tex- s at Arlington (UTA), an actively controlled, high-rate HESM has been created to evaluate its performance under the standard load condition presented by directed energy weapons. It's been assembled using LIBs, EDLCs, and business off-the-shelf Power Electronic converters. A discussion about the longer term of HESMs, the experimental setup at UTA, and also the results obtained therefore way can be presented here.
