The invention provides a traction battery pack assembly method. The battery pack assembling method comprises the following steps: compressing at least one battery cell stack; inserting at least one cell stack into a cell receiving opening of the housing structure; and using a pusher to push the at least one cell in the at least one cell stack out of the housing structure. Another traction battery pack assembly method includes moving a stack of cells from a compression jig that compresses the stack of cells into a housing structure. The cell stack includes a plurality of battery cells. After movement, the method compresses the stack of cells using a housing structure. The method then includes establishing an electrical connection between the battery cells of the cell stack, and testing the electrical connection prior to securing the bus bar to the cell stack. 本公开提供"牵引电池组组装方法"。一种电池组组装方法包括：压缩至少一个电芯堆；将至少一个电芯堆插入外壳结构的电芯接收开口中；以及使用推动器来将至少一个电芯堆中的至少一个电芯推出外壳结构。另一种牵引电池组组装方法包括将电芯堆从压缩电芯堆的压缩夹具移动到外壳结构中。电芯堆包括多个电池电芯。在移动之后，所述方法
