1. A multi-cell rechargeable energy storage system (RESS) comprising:
a plurality of battery cells organized into battery modules;
a first enclosure configured to house the battery modules;
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;
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; and
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, and thereby, in combination with the first vent, generate crossflow ventilation through the first enclosure to cool the battery modules therein and mitigate thermal runaway.
