Abstract: A fluid-cooled electronics assembly for high-power electronics includes an arrangement of electronic components that defines an upper-side of the arrangement and a lower-side of the arrangement opposite the upper-side. An upper-chamber is thermally coupled to the upper-side, and a lower-chamber thermally coupled to the lower-side. The upper-chamber and the lower-chamber are further configured to direct flowing-coolant series-wise from the lower-chamber into the upper-chamber. The upper-chamber and the lower-chamber are further configured to cooperatively define a manifold-connection operable to couple the assembly to a manifold-outlet and a manifold-inlet of a coolant-manifold. The assembly also includes a fitting configured to define an inlet-port of the assembly that directs the flowing-coolant from the manifold-outlet to the lower-inlet, and an outlet-port that directs the flowing-coolant from the upper-outlet to the manifold-inlet.

Abstract: A battery assembly internal connection device for making an electrical connection within a battery assembly that includes a plurality of cells. The device is operable from a pre-stage position where no electrical connection is made to a final position where an electrical connection is made. The device includes a terminal configured to make electrical contact with a first electrode of a cell when the device is operated to the final position. The terminal may optionally include a sharp portion configured to cut through dielectric material covering the first electrode as the device is operated from the pre-stage position to the final position.

Abstract: A complex wave spring, or Beer Spring™, for electrically coupling opposed electrical contact surfaces or generating a relatively constant force. The spring includes a first wave portion shaped to define a first upward undulation and a first downward undulation, and a second wave portion fixedly arranged relative to the first wave portion. The second wave portion is shaped to define a second upward undulation proximate to the first downward undulation, and a second downward undulation proximate to the first upward undulation. The spring may be formed of electrically conductive material suitable for electrically coupling electrical contact surfaces when the spring is in contact between the surfaces. The complex spring provides unusually constant spring forces over a relatively wide range of compression distances.
