Abstract
An active thermal runaway mitigation system is provided that mitigates the effects of a single cell undergoing thermal runaway, thereby preventing the propagation of the thermal runaway event to neighboring cells within the battery pack. The provided system includes at least one, fluid-containing conduit in proximity to the cells within the battery pack. The conduit includes a plurality of breach points in proximity to the subset of cells, where each breach point is configured to form a breach at a preset temperature that is lower than the melting temperature of the conduit. Once a breach is formed, the fluid contained within the conduit is discharged through the breach.
