DRS/Lithiumstart partnership aims at high-reliability shipboard military energy storage
MILWAUKEE, 8 Dec. 2014. DRS Power and Control Technologies Inc. in Milwaukee is joining hands with Lithiumstart LLC in South San Francisco, Calif., to integrate technologies into high-power commercial and military energy storage applications.
Power electronics experts from the two companies will combine DRS power electronic modules with Lithiumstart’s BluFlex Energy Storage System (ESS) technology to create a powerful and scalable energy storage module, officials say.
The DRS power electronic modules provide high-density power conversion capability, while the Lithiumstart BluFlex ESS consists of commercial off-the-shelf (COTS) 48-volt stacking modules for marine, stationary, and vehicle applications ranging from 50 kilowatts to 100 megawatts, and from 48 volts to 2 kilovolts.
The combined systems are for naval surface warships to provide stable backup power, fuel-efficient operations, and reduced total ownership costs, company officials say. Additional markets include commercial work boat applications and other military systems.
DRS power electronic modules are on several U.S. Navy platforms and programs. Lithiumstart’s ESS technology capitalizes on internal and U.S. Department of Defense investment in high-power density storage including U.S. Missile Defense Agency and Army applications.
The DRS/Lithiumstart system is scalable from 500 kilowatts to tens of megawatts. The joint Energy Storage Module is for pulse power with improved overall safety and reliability driven by lithium iron phosphate chemistry and by limiting the stored energy content consistent with the application and mission.
