Abstract: An electrochemical device is disclosed that includes a plurality of cells that each include a face, wherein a terminal is disposed on the faces of each respective cell. A bus bar has a bus bar height and electrically couples the terminals from cell-to-cell within the electrochemical device. A plurality of sheets are disposed between the plurality of cells, the plurality of sheets are substantially the same height as the combined, height of each cell and bus bar.

Abstract: Battery enclosures include a pre-stressed bottom sheet having a convex surface, at least one vibration isolator disposed along at least a portion of a perimeter of the bottom sheet, a sidewall in contact with the at least one vibration isolator so as to be isolated from the bottom sheet, and at least one strap attached to the bottom sheet, the at least one strap being configured to hold a bottom surface of an outer casing of a battery against the convex surface of the bottom sheet such that internal battery cells are supported by a substantially planar surface.

Abstract: A system is provided for connecting a battery to a mounting system. The battery is coupled to a battery connector, and the mounting system is coupled to a mounting system connector. The system includes an inner housing of the battery connector configured to receive a plurality of cables from the battery. The system further includes a respective plurality of male connectors or female receptacles positioned within the inner housing of the battery connector and coupled to the plurality of cables. The plurality of male connectors or female receptacles is configured to remain unexposed upon disconnecting the battery connector from the mounting connector during an unsafe event. The system further includes an outer housing of the battery connector surrounding the inner housing, where the outer housing includes a tapered wall.

Abstract: Batteries are disclosed that include a plurality of cooling plates, a plurality of cells disposed between adjacent cooling plates, a plurality of insulating sheets disposed between adjacent cells, a plurality of bus bars interconnecting the plurality of cells, an inner casing surrounding the plurality of cooling plates, the plurality of cells, the plurality of insulating sheets, and the plurality of bus bars, an outer casing surrounding the inner casing so as to form a gap therebetween, a layer of insulating material disposed inside at least a portion of the gap, and several other structural features in different embodiments of the invention configured to prevent motion of the cells relative to one another.

Abstract: Battery enclosures include a pre-stressed bottom sheet having a convex surface, at least one vibration isolator disposed along at least a portion of a perimeter of the bottom sheet, a sidewall in contact with the at least one vibration isolator so as to be isolated from the bottom sheet, and at least one strap attached to the bottom sheet, the at least one strap being configured to hold a bottom surface of an outer casing of a battery against the convex surface of the bottom sheet such that internal battery cells are supported by a substantially planar surface.

Abstract: A crankcase ventilation system for a reciprocating internal combustion engine includes an exhaust outlet and a collector for gathering gases from the engine crankcase. An eductor is connected to the collector and to the exhaust outlet. The eductor includes a generally cylindrical body extending into the exhaust passage of the exhaust outlet and having discharge, clean out, and receiver ports, so that crankcase gases will be drawn through the eductor and discharged into exhaust flowing through the exhaust outlet.
