    Abstract: A battery cell includes a cathode casing forming all or a majority of the external can of the battery cell. The battery further includes an anode tab covering at least a portion of a face of the battery cell and an insulating layer for electrically isolating the anode tab from the cathode casing. A plurality of such battery cells may be arranged within a battery pack in contact with each other, and may be held in compression. A conduction enhancement layer may be applied between the anode tab of a first cell and the cathode casing of a second cell within the battery pack. One or more heat dissipation elements may be arranged within the battery pack, in contact with the battery cells.

    Abstract: A system includes a source that provides air, a first compressor stage that receives the air from the source and is configured to compress the air to a first pressure, and a second compressor stage that receives the air from the first compressor stage and is configured to compress the air to a second pressure. The system also includes a first component, a second component, valves that control flow of the air, and a controller that is configured to control the valves according to a first control mode, in which the air is supplied to the first component by the first compressor stage, and a second control mode, in which the air is supplied to the second component by the second compressor stage.

    Abstract: A battery quenching system includes a reservoir that holds a quenching material. The battery quenching system further includes a distribution system for carrying the quenching material from the reservoir to a battery pack, a battery module, or a plurality of battery cells. The battery quenching system further includes a melting plug configured to melt at a predefined temperature, the melting of the plug resulting in release of the quenching material into the battery pack via the distribution system. The melting plug may be positioned within a tube of the distribution system or within an aperture of a battery enclosure. The battery quenching system may further include one or more quenching channels positioned within a battery pack. The distribution system may be configured to carry the quenching material to any or several of a plurality of locations within a battery pack or battery system.

    Abstract: A ball screw spline actuator includes a shaft, a ball nut, and a ball spline. The shaft includes a helical groove and a spline groove intersecting the helical groove forming intersections having a least one ridge including a first surface finish formed by a first manufacturing operation. The ridge is subsequently reformed through a second manufacturing operation to include a second surface finish to reduce stress concentrations in the ridge from cyclical loading from at least one of the ball nut or the ball spline. In one example, the second manufacturing operation reforms the ridge to include a surface finished edge.

    Abstract: A system includes a compressor that receives air from a source and is configured to supply compressed air, a first system that is configured to receive the compressed air, and a second system that is configured to receive the compressed air. In first control mode, a first control valve blocks flow of compressed air to the first system and a second control valve allows flow of compressed air from to the second system. In a second control mode, the second control valve allows flow of the compressed air from the second system to a dryer along, and the first control valve allows flow of the compressed air from the dryer to the first system.
