The presentation will lay out a phased approach which current understanding suggests may be the most effective in managing large scale battery failures and fires. Given the current environment of lacking data and codes still in development, this presentation will pull from all testing conducted to date as well as experiences from the design and implementation of tiered fire detection and suppression systems. The presentation will focus on how technologies available now may stack in complimentary fashion to cover all aspects of a lithium ion battery failure from single cell failure onset through to propagation, the incipient fire stage, and full system involvement with specific emphasis on detection of failure, determination of fire stage and threat, and thermal management for suppression.
