“…Whilst this study represents a beginning of life assessment of the ESS to meet LDEW demands, the operational stress conditions of repetitive, high current discharge rates could promote cell aging, whereby the cell capacity fades and internal resistance increases as discussed in Huhman et al (2016). Consequently, aging affects will influence whether the LDEW can operate for four minutes when the ESS is within the SOC ranges established in this work.…”

“… Thermal stress and cyclic aging effects are outside of the scope of this model. The potential effects from repetitive operation of parallel cells at elevated discharge rates are discussed further in Huhman et al (2016) and Wetz et al (2015).…”

“…Battery based pulsed power is not in itself a novel concept, Huhman et al (2016) describe the design of a battery system used to charge a capacitive device capable of delivering 12 kJ/s at 10 cycles per minute for a 5 minute, 50 shot salvo. Gattozzi et al (2015) investigated the ability of a Li-ion Energy Storage System (ESS) to power sub 125 kW LDEW loads, however little discussion was offered on the Li-ion battery model fidelity.…”

“…Gattozzi et al (2015) investigated the ability of a Li-ion Energy Storage System (ESS) to power sub 125 kW LDEW loads, however little discussion was offered on the Li-ion battery model fidelity. This investigation differs for two reasons, firstly the battery system is the sole source for the pulsed load as opposed to a battery/capacitor combination for electromagnetic launch purposes as researched by Huhman et al (2016). Secondly, the investigated LDEW loads are significantly greater, being 1.5, 1.75 and 2 MW, and could be required to power the pulsed load for a period of at least four minutes (Markle 2018).…”

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.

“…A review of the literature highlighted a gap in the understanding of the capability of batteries when used in pulse power applications. Publications on batteries used to power pulsed loads are few [2,10,11] and includes the authors' own publications [12,13]. Simulation-based work in [2] has demonstrated that lithium iron phosphate (LFP)-based li-ion batteries could be capable of providing for such loads.…”

The supply of pulsed power loads is considered a key driver for the integration of energy storage systems (ESSs) with warship power systems. ESSs are identified as a means to offer fast response dynamics capable of driving pulsed loads for sustained periods. This paper contributes a novel investigation into the performance of a Nickel Manganese Cobalt based lithium-ion battery system to supply laser directed energy weapon (LDEW) loads for future warship combat power systems using time-domain simulation methodology. The approach describes a second order Thévenin equivalent circuit battery model validated against a battery module of a type used in commercial marine ESS. The ability of the battery system to power LDEW loads peaking at 2 MW for up to periods of four minutes were simulated for beginning of life (BoL) and degraded conditions. The repeatability of the pulsed power supply with ESS is also reported. Simulation results show that Quality of Power Supply (QPS) is maintained within acceptable transient tolerance using a feed-forward control circuit that controls the DC-DC converter interface between the battery system and the LDEW load. The results of the study demonstrate the battery system operating envelope for the LDEW under investigation.
