1. A battery pack, comprising:
an enclosure assembly including a polymer-based component that establishes at least a portion of an outermost surface of the battery pack; and
a channel or tubing integrated into a floor of the polymer-based component,
wherein the floor establishes an interior component contacting surface of the polymer-based component,
wherein the channel or tubing is configured to establish a cooling circuit for thermally managing a battery internal component housed within the polymer-based component;
wherein the channel is a molded-in channel formed in the floor of the polymer-based component, and comprising a heat exchanger plate received over the molded-in channel to establish a serpentine passage of the cooling circuit between the channel and the heat exchanger plate; and
wherein the heat exchanger plate is secured to the polymer-based component by an overmolding.
