Abstract: A traction battery assembly includes battery arrays and a thermal exchange assembly of a battery pack. The thermal exchange assembly has passageways that each communicate coolant from a first side of the battery pack to an opposite, second side of the battery pack. An inlet conduit is on the first side. The inlet conduit is arranged such that the delivering of coolant to a first one of the passageways is upstream from the delivering of coolant to a second one of the passageways. An outlet conduit is on the second side. The outlet conduit is arranged such that the receiving of coolant from the first one of passageways to the outlet conduit is upstream from the receiving of coolant from the second one of the passageways to the outlet conduit.

Abstract: This disclosure details exemplary battery pack designs, such as those designed for use within electrified vehicles. Exemplary battery packs may include an enclosure assembly and a plurality of battery arrays housed inside the enclosure assembly. The enclosure assembly may include a mid-tray that is configured for supporting, cooling/heating, and sealing second tier battery arrays. The configuration of the mid-tray allows coolant joints to be eliminated inside of the battery pack.
