Abstract

As the US Navy transitions to a more electrical fleet, electrical load profiles will exhibit characteristics that have not been traditionally encountered. Conventional power generation devices are unable to meet the unique demands of these load profiles and so must be bolstered with energy storage devices to alleviate transient loading. Active hybrid energy storage modules offer both high-energy and high-power density when compared to traditional energy storage devices. Fuzzy logic control offers a method of controlling such a system to meet MIL-STD-1399 requirements on a shipboard system while requiring little knowledge of the system components. This paper evaluates a fuzzy logic controller’s ability to maintain an energy storage module voltage while accommodating a bi-directional transient load that is representative of one that could be seen aboard a naval vessel.&nbsp

Abstract

State-of-Health (SoH) is a critical parameter for determining the safe operating area of a battery cell and battery packs to avoid abuse and prevent failure and accidents. Experiments were performed at the US Naval Research Laboratory (NRL) on a 4P1S cell array using pulsed discharge and electrochemical impedance spectra (EIS) to determine a single-point SoH frequency for the array as a whole. Individual cell EIS measurements were taken, as well as measurements of the array as a whole. This work will discuss experimental results to date. (C) The Author(s) 2017. Published by ECS.
