Fail Safe Battery Management System for Aircraft Lithium-Ion Batteries Navy STTR FY2015.A Sol No.: Navy STTR FY2015.A Topic No.: N15A-T001 Topic Title: Fail Safe Battery Management System for Aircraft Lithium-Ion Batteries Proposal No.: N15A-001-0088 Firm: Creare LLC 16 Great Hollow Road Hanover, New Hampshire Contact: David Fogg Phone: (603) 643-3800 Web Site: http://www.creare.com Abstract: Fault dynamics of large format lithium-ion (Li-ion) battery packs are complex, difficult to predict, and challenging to protect against. Consequently, there is great interest in developing fault mitigation strategies to optimize pack performance and prevent individual cell failures from propagating to other cells or the host platform. During this program we will evaluate active monitoring and control strategies to improve the safety, performance, and reliability of Li-ion battery packs. During Phase I we will leverage previously developed Li-ion battery analytical models and Battery Management System technologies and demonstrate feasibility with a subscale prototype. During Phase II we will complete development and conduct testing with a full-scale battery pack. Benefits: The primary benefit of this program is the development of an advanced Battery Management System with built-in fault mitigation strategies that improve safety for a broad range of chemistries, capacities, and configurations. This technology will enable the safe use of large format Li-ion battery packs for a range of aircraft; Hybrid and Electric Vehicles; and unmanned land, air, and sea vehicles. Return
