  • Patent number: 9406918
    Abstract: A battery assembly including a plurality of battery cells and at least one frame having a support feature formed thereon is disclosed. The support feature supports electrically conductive tabs of the battery cells and militates against damage to the battery assembly during a joining of one of the electrically conductive tabs with another one of the electrically conductive tabs of an adjacent battery cell or during a joining of the electrically conductive tabs of adjacent battery cells with a connector.
    Type: Grant

  • Patent number: 8574320
    Abstract: A press apparatus for assembly of a battery pack includes a tooling table having an aperture formed therein. The tooling table includes a plurality of index pawls disposed adjacent the aperture. The index pawls militate against the components passing upwardly through the aperture after the components have passed downwardly through the aperture. A first press is disposed on a first side of the tooling table and configured to advance the components downwardly through the aperture and past the index pawls on the tooling table. A second press is disposed on a second side of the tooling table. The second press is configured to retract a distance that the components are pressed downwardly through the aperture and maintain a substantially constant upward force on the components. A third press is disposed on the first side of the tooling table and configured to compress the battery pack to a desired size and load.

  • Patent number: 6931901
    Abstract: Method and apparatus are disclosed wherein a required threaded hole is formed in a hydroformed part with a single tool while the part remains in a hydroforming die cavity. In forming the threaded hole, a hole is first pierced in the wall of the part and then an annular region of the part extending about the hole is extruded inwardly to form an integral tubular neck defining a hole of predetermined depth. The hole is then expanded in a sizing operation to a diameter determined by the required thread to be formed therein by material displacement and the required thread is then formed in the wall of the hole in a material displacing manner.

  • Patent number: 6658908
    Abstract: A punch for piercing and sealing hydroforming parts has a roll forming surface that produces an internal rolled edge portion in a formed part immediately following the punch piercing the part wherein the rolled edge portion acts to effect a tight high pressure seal between the part and the punch as the punch continues to form a required hole in the part. The roll-forming surface extends either partially or completely about the punch in determining the extent of the rolled edge portion in the part that it produces and is located between an end portion that effects the piercing operation and a larger finishing portion that completes the formation of the required hole.
