Abstract: Exemplary systems and methods enable efficient and reliable positioning, assembly, retention, interconnection, and management of battery cells in battery packs, for example battery packs utilized in electric vehicles.

Abstract: A battery pack assembly comprises a battery enclosure having a first side panel, a second side panel, a third side panel, a fourth side panel, a top panel, and a bottom panel defining a module containing volume. The battery pack assembly may contain a plurality of battery modules in the module containing volume, the plurality of battery modules having a first battery module, a second battery module, and a third battery module. The first battery module and the second battery module are positioned in a first orientation and stacked to form a column of battery modules and the third battery module is positioned in a second orientation and positioned adjacent to the column of battery modules.

Abstract: Systems and methods for a battery pack are disclosed. A battery pack tab cooling system is disclosed that includes a pouch cell comprising a first tab and a second tab. The battery pack tab cooling system also includes an enclosure configured to contain a cooling material. The first tab and the second tab extend from the pouch cell into the enclosure and are in contact with the cooling material. A method of manufacturing a battery pack that includes forming the battery pack, the battery pack comprising and cooling the at least one of the first tab and the second tab to cool the pouch cell.

Abstract: A cold plate for a battery may comprise channels that extend from a first end of the plate to a second end of the plate or from a first side of the plate to a second side of the plate, the channels are located in parallel with each other and between the top surface and the bottom surface. The channels may be separated from each other by walls. The plate may be milled to form a first manifold on each end. The plate may also be milled to form notches in the surface(s) over the manifold. A port for the inlet and a port for the outlet of a working fluid may be inserted into the notches. The plate may have end caps, and the end caps and the ports may be welded or brazed to form a sealed enclosure. In various embodiment, the plate is an extruded plate, a cast plate, or a stamped/formed plate.

Abstract: The disclosure describes techniques for forming a surface layer of an article including a CMC using a cast. In some examples, the surface layer includes three-dimensional surface features, which may increase adhesion between the CMC and a coating on the CMC. In some examples, the surface layer may include excess material, with or without three-dimensional surface features, which is on the CMC. The excess material may be machined to remove some of the excess material and facilitate conforming the article to dimensional tolerances, e.g., for fitting the article to another component. The excess material may reduce a likelihood that the CMC (e.g., reinforcement material in the CMC) is damaged by the machining.

Abstract: A battery cell is made more thermally efficient with the addition of an integrated vapor chamber that extends out from the cell and into an external heat exchange interface. The integrated vapor chamber can contain a working fluid which undergoes phase changes between liquid and vapor phases when there is a temperature differential between the interior and exterior of the cell. The integrated vapor chamber can include a wicking material to transfer the working fluid to the exterior wall of the vapor chamber. The integrated vapor chamber allows for both heating and cooling of the battery cell.
