LYNNTECH INC. — Department of Defense SBIR Phase II: The demand for greater and safer energy storage for the wet and dry submersibles and buoys

Description

The demand for greater and safer energy storage for the wet and dry submersibles and buoys has pushed the limits of current battery technology. This energy demand is in response to the need for extended mission operations and advances in electronic equipment needed for greater combat effectiveness. By replacing the existing battery with a fuel cell hybrid system, extended operation periods are possible while reducing the safety risk. In a hybrid system a high power source is used to handle start up and peak power demands while the fuel cell is used to provide the nominal power and recharging energy. This configuration allows for both components to be sized specifically for the power needed. To efficiently distribute the power, a proprietary power management system architecture is utilized that is able to adjust to the power demands and maintain a high system efficiency. The control logic which includes the power management system also monitors the system health to ensure safe operation. During the project, Lynntech will develop components for a fuel cell hybrid power system for wet and dry submersibles and buoys. The development of a fuel cell hybrid system for these platforms will extend mission times and increase safety.
