The present disclosure provides a battery cell grouping solution for a traction battery pack. A battery cell grouping solution for assembling a traction battery pack including a cell-pack battery system is disclosed. A cell grouping assembly may be used to establish a common fiducial reference plane with respect to a plurality of battery cell groups. An exemplary method of assembly may include positioning the battery cell pack relative to the cell packet assembly and then applying a compressive force to the battery cell pack to provide a cell stack of the cell-pack battery system. The grouped stack of cells may then be positioned to a housing tray of the traction battery pack. 本公开提供了"用于牵引电池包的电池电芯分组解决方案"。公开了用于组装包括电芯-电池包电池系统的牵引电池包的电池电芯分组解决方案。电芯分组总成可以用于相对于多个电池电芯组建立公共基准参考平面。一种示例性组装方法可以包括相对于所述电芯分组总成定位所述电池电芯组，然后向所述电池电芯组施加压缩力以提供所述电芯-电池包电池系统的电芯堆。然后可以将分组的电芯堆定位到牵引电池包的外壳托盘。
