AB  - In the future warship power and propulsion systems need to be designed for increased flexibility, in part to sustain the demand of changing load profiles such as those characterised by high ramp-rates of new weapons and sensors intended to support enhanced future warfighting capability. Lithium-ion based battery performance is improving at a prominent pace in the automotive sector, increasing in both energy and power density, thus there is now an opportunity to exploit these characteristics for naval power systems. A common use energy storage system could facilitate benefits such as reduced fuel burn and prime mover running hours by reducing the number of running generator sets. Importantly, the improvement in battery systems, has reached a juncture where the technology could be considered to support directed energy weapons. The feasibility of a Lithium-ion NMC based energy storage system, capable of high discharge rates, to power predicted laser directed energy weapons using time domain simulation is investigated in this paper. Results verify that the simulated system is capable of high rates of fire for extended periods subject to state of charge operating limitations.
