ENCLOSURE COVER ATTACHMENT CONFIGURATIONS FOR TRACTION BATTERY PACKS WITH CELL-TO-PACK BATTERY SYSTEMS

Cover attachments are disclosed for securing an enclosure cover to a cell row/battery cell separator on traction battery packs that include cell-to-pack battery systems. One or more separators of a cell-to-pack battery system may be configured to separate cell stack rows or battery cells within the cell-to-pack battery system. A cover attachment (e.g., a clip, an adhesive puck, a magnet assembly, a hook and loop assembly, a ball-and-socket assembly, etc.) may connect to a portion of the separator for securing the enclosure cover directly to the cell-to-pack battery system. The combination of the cover attachments and the separators provides for enclosure cover retention at interior regions of the cell-to-pack battery system, maintains the enclosure cover at a spaced distance apart from the battery cells of the cell-to-pack battery system, and creates a desired amount of pack-level stiffness for distributing loads through the cell-to-pack battery system.
