    Abstract: A system for joining a first part and a second part together with a weld structure. The system includes: a welding element configured to form the weld structure between the first part and the second part; and a control module configured to operate the welding element to form the weld structure. The weld structure includes: a first curved end; a second curved end; a connecting portion connecting the first curved end and the second curved end; a first curved crown spaced apart from the first curved end and concentric with the first curved end; and a second curved crown spaced apart from the second curved end and concentric with the second curved end. The first curved end, the second curved end, and the connecting portion are between the first curved crown and the second curved crown.

    Abstract: A battery enclosure to house a battery pack of an electric vehicle includes a bottom plate, a battery pack including multiple batteries or battery modules, a frame enclosure at least partially surrounding the battery pack, the frame enclosure connected with the bottom plate, the frame enclosure including at least a first side wall and a second side wall, and multiple cross members each extending between the first side wall and the second side wall. The battery enclosure includes a top plate configured to cover the multiple structural cross members and at least a portion of the battery pack. The top plate is connected with the frame enclosure and includes multiple ridges protruding from a top surface of the top plate, each ridge defining a channel extending parallel to the top surface of the top plate, and each channel configured to facilitate flow of a heat transfer medium through the channel.

    Abstract: A battery cell including a stack and a first internal terminal. The stack includes: C cathode electrodes each including a cathode current collector, a cathode active layer arranged on the cathode current collector, and an external connector extending from the cathode current collector; A anode electrodes each including an anode current collector, an anode active layer arranged on the anode current collector, and an external connector extending from the anode current collector; and S separators, where C, A, and S are integers greater than one. Each one of the external connectors, of one of the C cathode electrodes and the A anode electrodes, includes a first tab and a second tab extending farther than the first tab, the second tabs are folded onto the first tabs, and the first internal terminal is laser welded onto the second tabs.

    Abstract: A robotic system for forming a moldable workpiece is provided. The robotic system includes a robot, an end effector, an adjustment module, and a control module. The robot is configured to pass the workpiece through a machine. The end effector is configured to be attached to the robot and configured to grasp and release the workpiece. The end effector is adjustable to a plurality of different configurations. The adjustment module is configured to determine a change in the workpiece from (a) a first form of the workpiece prior to the passing of the workpiece through the machine to (b) a second form of the workpiece after passing of the workpiece through the machine. The control module is configured to adjust a present configuration of the end effector to a second configuration based on the change in the workpiece from (a) the first form to (b) the second form.
