摘要： Structural cross-member assemblies are provided for traction battery packs. An exemplary cross-member assembly may include a cross-member beam having a beam body and at least one reinforcement section that provides structural integrity to the beam body. The reinforcement section may be a pultrusion and may embody various cross-sectional shapes. The cross-member beam may be positioned adjacent to an additional cross-member beam to establish the cross-member assembly disposed between adjacent cell stacks of the traction battery pack.

摘要： A traction battery pack for an electrified vehicle may include a protection bracket for shielding a vent feature of the traction battery pack. An exemplary protection bracket may be made of a polymeric material and is designed to shield the vent feature from debris impingement. The protection bracket may include features such as a mesh venting pattern and a melting point that is lower than the temperature of battery vent byproducts that may be released during battery thermal events of the traction battery pack.

摘要： Battery cell grouping solutions are disclosed for assembling traction battery packs that include cell-to-pack battery systems. A cell grouping assembly may be utilized to establish a common datum reference plane relative to multiple groupings of battery cells. An exemplary assembly method may include positioning the groupings of battery cells relative to the cell grouping assembly, and then applying a compressive force to the groupings of battery cells to provide cell stacks of the cell-to-pack battery system. The grouped cell stacks may then be located to an enclosure tray of the traction battery pack.

摘要： Manufacturing processes are disclosed for assembling traction battery packs that include cell-to-pack battery systems. An exemplary assembly method includes inserting a cell matrix of the cell-to-pack battery system into a cell-compressing opening of an enclosure tray using a top-down approach. The method may include compressing a plurality of cell stacks to a desired length, compressing the cell stacks together in a transverse direction to form the cell matrix, and then installing the cell matrix as a single unit into the cell-compressing opening of the enclosure tray.

摘要： Traction battery packs are disclosed that include cell-to-pack battery systems. A cell stack/cell matrix of the cell-to-pack battery system may be positioned within an irregularly shaped enclosure tray of the traction battery pack. A block insert may be positioned at an interface between the cell stack/cell matrix and an irregularly shaped interior surface of the enclosure tray. The block insert may be configured to facilitate insertion of the cell stack/cell matrix into the enclosure tray, transfer compression loads from the enclosure tray walls to the cell stack/cell matrix, resist battery cell compression loads, etc.
