Tactical Power

West Coast Solutions specializes in expeditionary and scavenging power technologies, including the development of custom batteries and the integration of complex solar and hybrid systems.

Hybrid Battery Supercapacitor (HBS)

The West Coast Solutions HBS enables a new generation of high-power payloads on SmallSats by providing >700W sustained power from a 1U (1000 cc) hybrid battery. Targeted applications include advanced propulsion technologies, lasercom, high data rate downlink transmitters, large array infrared sensors, synthetic aperture radar (SAR), and directed energy. TRL 6 testing of a flight-design prototype is underway on a Missile Defense Agency SBIR Phase II-E. Applied Vibration was completed in December 2024, and Thermal Vacuum and EMI testing are on track for February 2024.

Extremely high-power-density battery, 2-3X competing technologies

High reliability, radiation tolerant space design
150 Wh energy and >700W power in 1U form factor
Cycle life > 30,000
Scalable for higher energy and higher power

Lightweight Expeditionary Power System (LEPS)

To meet the US Marine Corps next generation expeditionary power needs, West Coast Solutions has developed LEPS. Having evolved from earlier Small Business Innovative Research programs, WCS is presently maturing LEPS to TRL 8 with the first system delivered to USMC and the TRL 8 test program now underway. LEPS provides a 2X SWaP improvement over the current art by virtue of the underlying next generation patented battery and power electronics technologies. LEPS is modular, scalable and reconfigurable to meet a wide range of sizes and applications.

Battlefield Airman Battery

WCS was the design and integration lead on the battery packaging effort for an Air Force Phase III SBIR subcontract to American Lithium Energy. Our focus was on thermal management to meet the aggressive 450W @ 65°C discharge requirement. WCS designed and implemented an extremely compact package that contains enough phase change material to meet requirements.

Compact, thermally efficient packaging for a high-power battery
Custom 18650 cells from ALE packaged into 9S2P format by WCS
Utilizes solid-liquid phase change material
Support 450W discharge up to 65°C baseplate temperature

Ultra-Compact Uninterruptible Power Supply (U-CUPS)

West Coast Solutions provided mission critical support to Jet Propulsion Laboratory in the selection, integrated design, and test of the Cryocooler Subsystem. One key task involved the design of a Cryogenic Thermal Demonstrator to experimentally determine the cryogenic thermal loads to be expected in the UCIS instrument. Additional program tasks included SolidWorks Simulation finite element thermal analysis and computational fluid dynamics to guide the heat sink designs.

Cryocooler selection and integration support for the UCIS airborne instrument
Cryogenic systems engineering support covering mechanical, thermal, exported vibration, and electrical (EMI)
Integration of tactical COTS cryocoolers onto the airborne instrument
Design, build, test and delivery of a portable cryocooler Purge and Charge Station
Onsite test support at Jet Propulsion Laboratory
