Abstract: A thermal management system for a rechargeable battery pack assembly includes 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. A sealing mechanism is configured to transition from a first state in which the sealing mechanism blocks flow of an applied stream of water through the conduit from the upstream end through the port, to a second state in which the sealing mechanism permits flow from the upstream end to the port and through the port into the interior cavity to cool the interior cavity.

Abstract: The present disclosure provides a battery pack component including a self-healing coating. The self-healing coating is disposed on at least a portion of a surface of the battery pack component. The self-healing coating includes a first precursor including a cyclic ether capable of reacting in a self-healing cationic ring-opening polymerization reaction. The self-healing coating further includes an initiator including an alkali metal salt. The self-healing cationic ring-opening polymerization reaction occurs when a defect is present in the self-healing coating. In certain aspects, the cyclic ether may include 1,3-dioxolane (C3H6O2) and the initiator may include lithium bis(fluorosulfonyl)imide (F2NaNO4S2). In other aspects, the self-healing coating may include a second precursor that is capable of copolymerizing with the first precursor. In still other aspects, the present disclosure provides a method of making a self-healing coating for a battery pack component.
