Exemplary battery packs may include a polymer-based enclosure assembly having features for thermally managing internal components of the battery pack. In some embodiments, the enclosure assembly may include molded-in fluid channels or molded-in tubing for establishing a cooling circuit of the battery pack. In other embodiments, the enclosure assembly may include molded-in channels that receive tubing for establishing a cooling circuit of the battery pack. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The battery pack as recited in claim 1, wherein the polymer-based component is a tray made of an expanded polymer-based material. ### Claim 3 (depends on 1) The battery pack as recited in claim 1, wherein the polymer-based component is a tray made of a solid polymer-based material. ### Claim 4 (depends on 1) The battery pack as recited in claim 1, wherein the heat exchanger plate is secured to the floor by a structural adhesive. ### Claim 5 (depends on 1) The battery pack as recited in claim 1, wherein the channel is a molded-in channel formed in the floor, and the tubing is received within the molded-in channel such that the battery pack includes both the channel and the tubing. ### Claim 6 (depends on 1) The battery pack as recited in claim 1, wherein the tubing is integrated into the floor by an overmolding. ### Claim 7 (depends on 1) The battery pack as recited in claim 1, wherein the battery internal component is a battery array, a bussed electrical center (BEC), or a battery electric control module (BECM). ### Claim 8 A battery pack, comprising: an enclosure assembly including a tray and a cover received over the tray; a molded-in channel formed in a floor of the tray, wherein the floor establishes an interior component contacting surface of the tray; a tubing received within the molded-in channel; a heat exchanger plate secured over the tubing; a structural adhesive or an overmolding securing the heat exchanger plate to the floor; a thermal interface material applied on the heat exchanger plate; and a battery internal component positioned in contact with the thermal interface material, wherein the thermal interface material is configured to facilitate thermal conductivity between the heat exchanger plate and the battery internal component.
