Multifaceted Study of Electrochemical Energy Storage Systems for Powering Future Shipboard Transient Electrical Loads
Abstract
Since 2010, the UT Arlington Pulsed Power and Energy Laboratory (PPEL) has been performing research in support the US Office of Naval Research (ONR) in several power and energy areas. As the US Navy begins to introduce more electrical loads into the fleet, the power and energy requirements will grow considerably. It is obvious that additional power generation will be needed aboard future ships to meet the increased electrical load but the transient nature of many of the loads being developed makes the choice of additional power generation a non-trivial task. Addingmore fossil fuel driven motor ~ generators aboard future ships will not be sufficient for driving high rate transient loads as the power quality is severely impacted when their load is not maintained. It has been previously demonstrated by UTA that buffering motor-generator sets with energy storage is a feasible and effective way of maintaining the power quality required to meetthe Navy~s shipboard electrical standards. In 2015, UTA demonstrated that a very cheap gasoline powered generator~s power quality is improved by using a fuzzy logic controlled hybrid energy storage module (HESM) made up of actively controlled lithium-ion batteries and ultracapacitors. In addition to this demonstration, UTA demonstrated in 2015 that both lead acid and lithium-ionbased batteries can be fabricated with open circuit potentials in excess of 1000 V and used to supply transient electrical loads at power rates in excess of 500 kW. Finally UTA has demonstrated that there is a significant current sharing imbalance when high capacity lithium-ion batteries are constructed using a high number of parallel cells and used to supply high power to transiently driven electrical loads. This document proposes the continuation and expansion of these research topics so that further fundamental insight can be gained into the role of actively controlled HESMsand electrochemical energy storage devices in the next generation of Navy ships. This proposal documents the accomplishments to date and details the statement of work proposed to carry the research to date to the next level.
