Abstract: A modular frame includes a first row of cell slots configured to receive first prismatic cells of a battery pack system. A second row of cell slots is configured to receive second prismatic cells of the battery pack system. A central interface beam is disposed between the first row of cell slots and the second row of cell slots. The central interface beam includes a first side and a second side. The first side is configured to receive terminals of the first prismatic cells. The second side opposes the first side and is configured to receive terminals of the second prismatic cells.

Abstract: A modular frame for a battery module includes: a floor that includes an electrically non-conductive material; end walls that are perpendicular to the floor and that include the electrically non-conductive material; and side walls that are perpendicular to the floor, that are perpendicular to the end walls, and that include the electrically non-conductive material. The modular frame further includes interior walls that include the electrically non-conductive material and that define: a first row of cell slots configured to receive a first plurality of prismatic cells; a second row of cell slots configured to receive a second plurality of prismatic cells; and a chamber disposed between the first and second rows of cell slots. The modular frame further includes a first and second apertures to the chamber. The first aperture is defined by the interior walls and the side walls. The second aperture is formed through one of the end walls.

Abstract: A battery pack according to the present disclosure includes a first module array, a second module array, and a center channel. The first module array includes a first frame and a first cassette of battery modules disposed within the first frame. The first cassette of battery modules includes a first plurality of prismatic cells and a first plurality of module terminals. The second module array includes a second frame and a second cassette of battery modules disposed within the second frame. The second cassette of battery modules includes a second plurality of prismatic cells and a second plurality of module terminals. The center channel extends through a center of the battery pack and connects the first module array to the second module array. The first plurality of module terminals and the second plurality of module terminals are disposed adjacent to the center channel on opposite sides of the center channel.

Abstract: A fluid quick connector includes concentrically joinable first and second endforms. A housing having an open end is carried on one endform and latchingly receives an adapter fixed on the other endform. An end of the adapter is biased into clamping engagement with one endform when the adapter engages the housing. In another aspect, the adapter includes two joinable sections which are fixedly mountable about one end of the first endform. A hollow insert is fixed within the end of the first endform and engages the end of the second endform in the adapter to seal the second endform to the adapter.

Abstract: Disclosed is a high-speed circuit in which a basic cell includes a high-speed first transistor and a high-speed second transistor. Both the first and second transistors have high gain-bandwidth products. The second transistor is a unipolar (field-effect) device which is connected in a cascode configuration with the first transistor. The unipolar device functions to control the operating point of the first transistor over a range from "on" to "off" as a function of the unipolar device operating at a point over the range from "on" to "off". The unipolar device is controlled by an input voltage signal applied to its gate.
