Abstract
A multi-cell rechargeable energy storage system (RESS) includes a plurality of battery cells organized into battery modules and a first enclosure configured to house the battery modules. The RESS also includes a first vent arranged on the first enclosure and configured to direct air from inside the first enclosure to an environment external to the first enclosure. The RESS additionally includes a second vent arranged on the first enclosure and configured to direct air into the first enclosure from the environment external to the first enclosure. The RESS further includes a phase-change material (PCM) device arranged on the second vent and configured to melt in response to at least one of the battery modules experiencing a thermal runaway event. In combination with the first vent, the PCM generates crossflow ventilation through the first enclosure to cool the battery modules therein and mitigate thermal runaway.
