1. A thermal management system for a rechargeable battery pack assembly, the thermal management system comprising:
a conduit having an upstream end and a downstream end, the downstream end operatively connectable to an enclosure of the rechargeable battery pack assembly at a port of the rechargeable battery pack assembly; and
a sealing mechanism configured to transition from a first state to a second state;
wherein the sealing mechanism blocks flow of an applied stream of water through the conduit from the upstream end through the port in the first state, and the sealing mechanism permits flow of the water from the upstream end to the port in the second state and through the port into an interior cavity defined by the enclosure to cool the interior cavity; and
wherein the enclosure has a drain opening positioned so that the water is ejected from the enclosure after at least partially filling the interior cavity of the enclosure.
