Battery Management, Monitoring and Diagnostic Device for Navy Energy Storage Modules Navy SBIR FY2011.3 Sol No.: Navy SBIR FY2011.3 Topic No.: N113-177 Topic Title: Battery Management, Monitoring and Diagnostic Device for Navy Energy Storage Modules Proposal No.: N113-177-0109 Firm: Yardney Technical Products, Inc. 82 Mechanic Street Pawcatuck, Connecticut 06379-2154 Contact: Greg Moore Phone: (860) 599-1100 Web Site: www.yardney.com Abstract: Yardney Technical Products in conjunction with Johns Hopkins University Applied Physics Laboratory is proposing to progress development of an advanced monitoring system for batteries, provide a modular battery unit, and develop a system approach to monitor and control multiple power sources and loads. Battery monitoring will be advanced via a technique to determine the internal temperature of each cell in a battery, thereby providing an opportunity to detect if a cell is approaching initiation of thermal runaway. The system will balance various parallel power sources to maintain thermal control of each by providing an opportunity to take one that is detected to be in jeopardy offline. The modular battery design will provide a unit consisting of cells and a battery management system, having advanced monitoring and control capabilities, as a standalone unit, or readily capable of arranging in a parallel and/or series configuration to meet requirements. This proposal addresses an advanced system monitoring and control approach, and a battery whose benefit is not to address "how to fail safely," but rather how to prevent failure by detecting the anomalous behavior of a cell well before it fails. Benefits: A systematic approach at power management via monitoring and control is paramount for providing for safe operation. In addition to safety, this is also a means to provide longer life for power sources, running them at their optimal conditions will provide for a decreased lifetime cost. With the ever-increasing needs for power for various applications, some requiring high power and others high energy, a systematic control and command on top of localized modular monitoring, will provide the capability of meeting these demands in a safe and efficient manger. The applications of this proposed advanced power system are numerous; nearly all applications that contain power sources large enough to cause significant monetary or physical harm. Government platforms include large-scale naval applications such as ships, unmanned and manned submersibles, as well as other military applications, and in the commercial market some potential markets include large-scale Uninterruptible Power Sources, hybrid electric vehicles, electric vehicles, and many more. In both the civilian and military operations involving battery and hybrid electric power, the proposed autonomous BMS has the potential to save lifetime costs; the cost savings can surpass the additional cost of existing advanced monitoring and control systems.
