Abstract: A battery module includes an array of electrochemical cells, and a frame configured to support the cells within the battery module, the fame encircling the array in such a way as to overlie the cell sidewall of each cell and expose the cell first end and the cell second end of each cell. The frame is surrounded by a spacer. The spacer includes a first wall portions that faces the cell first ends, and a second wall portion that faces the cell second ends. The first and second wall portions include grooves that serve as coolant fluid passages. The frame is disposed in the spacer interior space in such a way that each of the cell first ends and each of the cell second ends are exposed to the fluid passages of the first wall portion and the second wall portion.

Abstract: Disclosed herein is a device for housing a plurality of electrochemical cells, wherein the housing provides stability, temperature control and maximum packing density. The battery module housing comprises a first semi-enclosure and a second semi-enclosure, wherein the first and second semi-enclosure are aligned to form compartments there between. Each compartment is designed to accommodate at least one electrochemical cell, such as a cylindrical battery or a prismatic battery. Each semi-enclosure comprises an interior wall and an exterior wall. The interior and exterior wall align together to form a flow path between the walls through which coolant or any other thermal management medium may flow. The coolant enters the semi-enclosure through a coolant inlet, flows between the interior and exterior walls; then flows out of the semi-enclosure through a coolant outlet.

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: There is provided a battery system having a plurality of battery modules having joined top, bottom and side surfaces. The battery modules are connected for providing a power source. Each of the plurality of battery modules includes a vent having a discharge outlet. The vent includes a portion that extends outward from a side of the battery module. A gas manifold having a gas discharge tube extending from a first end to a second end includes a plurality of tubular ports positioned between the first and second ends of the gas discharge tube. The plurality of tubular ports extend radially outward from the gas discharge tube and are coupled to each of the vents of the plurality of battery modules.

Abstract: A multi-cell battery comprising a housing having one or more partitions dividing the housing into a plurality of regions. A dielectric material lines the surfaces of the housing within each of the regions and an electrochemical cell is disposed within each of the regions. The housing is used as a heat sink to draw heat away from the individual electrochemical cells during operation.

Abstract: A hydrogen storage unit which uses hydrogen storage alloys to store hydrogen, and more particularly a heat transfer management/compartmentalization system for use in such system. The hydrogen storage alloy may be divided into compartments, separated by discs, further divided into sub-compartments by a flapper wheel. The discs and flapper wheel provide for optimal heat transfer throughout the system. The compartmentalization of the vessel may prevent compaction of the hydrogen storage alloys, which could lead to excessive strain on the vessel causing damage, deformation, or rupture of the vessel.
