Publication number: 20240154188Abstract: Provided are battery packs and interface modules for electrically interconnecting electrochemical cells in the packs and for providing heat distribution with the packs. An interface module interfaces one side of all electrochemical cells in a battery pack. The interface module may have a substantially planar shape such that the space occupied by the module in the battery pack is minimal. Most, if not all, conductive components of the interface module may be formed from the same sheet of metal. In some embodiments, the interface module includes multiple bus bars such that each bus bar interconnects two or more terminals of different electrochemical cells in the battery pack. Each bus bar may have a separate voltage sense lead extending from the bus bar to a connecting portion. The bus bars may be flexibly supported within the module. The interface module may also include multiple thermistors disposed on different bus bars.Type: ApplicationFiled: August 14, 2023Publication date: May 9, 2024Inventors: Weston Arthur HERMANN, David E.

Patent number: 9190675Abstract: A component for reducing the likelihood of ice-related blockage in a fuel cell and methods for starting a fuel cell system. In one embodiment, the component is a separate insert configured with a sharp leading edge such that water droplets present in a reactant fluid that pass through an orifice in the component are conveyed away from an unstable formation at the edge to a more stable formation in an adjacent part of the component. In one form, the component is sized to fit within a valve inlet that in turn is placed in a humid reactant flowpath. In this way, when the fuel cell is operated in cold conditions—such as those associated with temperatures at or below the freezing point of water—the water droplets do not freeze in the area around the orifice such that ice-related blockage of the flowpath does not occur.Type: GrantFiled: May 6, 2013Date of Patent: November 17, 2015Assignee: GM Global Technology Operations LLCInventors: Stuart D. Barter, Jon P. Owejan, Christopher J. Towner

Patent number: 9065158Abstract: A cooling module for a battery pack assembly is disclosed. The cooling module includes a frame having a plurality of legs forming an opening through a central portion of the frame, at least one of the plurality of legs including a slot formed therethrough. A cooling fin is coupled to the frame. The cooling fin includes a corrugated plate interposed between a first plate and a second plate forming a plurality of fluid flow channels between the first plate and the second plate. The cooling modules are disposed in a stack having at least one battery cell disposed between adjacent cooling modules. The battery cell is in heat transfer communication with the cooling fin of at least one cooling module, wherein the cooling fin facilitates a transfer of heat energy between the battery cell and the flow channels formed in the cooling fin.Type: GrantFiled: May 28, 2010Date of Patent: June 23, 2015Assignee: GM Global Technology Operations LLCInventors: William L. Martz, Michael Duffield, Megan J. Quick, Stuart D. Barter, Glenn W. Skala, Steven J. Fogarassy, Eric J. Connor, Thaddeus J. Grey

Patent number: 8889289Abstract: A fixture is configured for holding terminals of a battery in alignment. The fixture includes a first and a second side member. The first and second side members each include a plurality of first and second teeth, respectively. The second side member is movable relative to the first side member between an open position and a closed position. The second side member opposes the first side member such that a number of the first teeth oppose a corresponding number of the second teeth and a slit is defined between each of the adjacent teeth when the fixture is in the open position. Likewise, the second side member opposes the first side member such that the number of the first teeth are staggered from the corresponding number of the second teeth to reduce the slit in size when the fixture is in the closed position.Type: GrantFiled: May 27, 2009Date of Patent: November 18, 2014Assignee: GM Global Technology Operations LLCInventors: Patrick J. Meehan, Stuart D. Barter, Robert J. Scheuerman, Rick F. Rourke
