Power & Energy
ARL's power and energy Technology Focus Area provides technologies that enable lightweight compact power sources and high power density components that will significantly reduce the logistics burden, while enhancing future capabilities such as survivability and lethality. Research efforts include: improved compact, high power, and energy density primary and auxiliary power sources; high density power switching devices and components; and related energy storage and sources for Army applications. Major investments include: power components for more electric vehicles and pulse power; power sources for Soldier power and auxiliary power; and micro power and energy scavenging for sensors, autonomous systems and Soldiers. The Power & Energy technology focus area is executed in five technology sub-areas.
Perform basic and applied research in fuel cell components and fuel reforming/ conditioning for fuel cells and APUs, in-situ energy conversion (PV, TE, isomer/isotopes), micro-power sources and power for microelectromechanical systems (MEMS), and selected other technologies (alternators, actuators energy efficiency) with focus on Soldier/sensor and mobile power regimes (microwatts to kilowatts).
Perform basic and applied research including synthesis, characterization and analysis on primary batteries, rechargeable batteries, thermal/reserve batteries, capacitors (pulse and continuous), and selected alternative energy sources such as packaged and alternative fuels for a wide range of applications and across Soldier/sensor, mobile, and weapons power regimes (microwatts to megawatts).
Power Control & Distribution
Perform basic and applied research in the areas of Si, SiC, and widebandgap power switches and devices; high power, high temperature power electronics (pulsed and continuous); high density, high efficiency power converters & inverters; intelligent power management; and high temperature magnetics and inductors for more electric vehicles, pulse power, and lethality applications primarily across mobile and weapons power regimes (kilowatts to megawatts).
Perform basic and applied research in thermal transport and control materials and techniques primarily as applied to high temperature power electronics and continuous and pulsed electric power subsystems; with focus on mobile and weapons power regimes (kilowatts to megawatts).
Perform basic and applied research that will enhance energy sufficiency by selective efforts exploring unique energy scavenging methods such as nanostructured photovoltaics; biomassed derived energy using photosynthesis and other techniques; multi-stage thermoelectric materials and devices; and related constructs for device and energy management implementations. Primary focus is within the Soldier/sensor power regime (microwatts to watts).
