Engineering Services: Unmanned Underwater Vehicle Integrated Battery Pack Program
Boeing contracted AeroVironment to design a nickel metal hydride (NiMH) rechargeable battery system and build a prototype for their portion of the Unmanned Underwater Vehicle (UUV) Program. Boeing, Oceaneering and Fugro partnered to develop the UUV, which is designed to map the ocean bottom at depths up to 10,000 feet and required a high power density battery system for economical operation. AeroVironment’s battery system consists of two rechargeable battery packs with integrated battery management and fast charging systems. Severe space constraints challenged AeroVironment to deliver a highly compact and efficient solution. The entire battery system was designed to fit into a 32-inch diameter by 44-inch long space and to weigh less than 2,100 pounds. The final design weight was 1,922 pounds.
