Investigating the Performance Capability of a Lithium-ion Battery System When Powering Future Pulsed Loads

“…Experimental verification of the remaining contributions is in the scope of future work. The consequences of degraded performance of li-ion NMC based battery systems on LDEW operation have were not reported in [2,10,11]. The significance of the work in this paper is to suggest that batteries can be used successfully in laser pulse load applications in warships.…”

“…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.…”

“…While the on-time of 5 s, is of comparable duration with anticipated LDEW loads [1,2] the capacitor load off-time, from the perspective of the battery, is 10 ms as the shot is taken. The work of [11] focused on power hardware in the loop testing of a 1000 V, 660 kW, 200 MJ li-ion battery. One of their aims was to present results of the commissioning and testing of the battery when supplying periodic and stochastic pulsating loads.…”

“…The battery system was subjected to two-level periodic 1 kA load pulses. The authors in [11] did not discuss the limitations of this loading on the operating envelope of the battery. Instead, their work contributed to the de-risking effort of integrating ESSs with warship power systems to supply pulsed loads.…”

“…Instead, their work contributed to the de-risking effort of integrating ESSs with warship power systems to supply pulsed loads. In [2,10,11], the discussion of the DC/DC converter control system to manage the pulsed power load was not included in the work.…”
