Fail Safe Battery Management System for Aircraft Lithium-Ion Batteries

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.
