Patent number: 11936017Abstract: A battery pack for an electric vehicle or a hybrid vehicle may include a housing, a stack of battery cells disposed within the housing, and a cooling subassembly. The housing typically holds the cell stack together, and the cooling subassembly typically cools the cell stack to prevent damage to the battery cells and to maintain the performance of the battery cells. The cooling subassembly may include a cold plate defining a liquid flow channel and one or more thermoelectric devices (TEDs) that are operable to cool the cell stack when current is supplied thereto. Heat spreaders may be employed within the battery pack, and exemplary configurations of components to thermally and mechanically couple the cooling subassembly are described.Type: GrantFiled: November 15, 2022Date of Patent: March 19, 2024Assignee: Hyliion Inc.Inventors: David Scott Thomas, Alex Ho Yang, Timothy Hughes

Publication number: 20140205671Abstract: A method of synthesizing PHA nanocapsules as a protein carrier, particularly, the synthesis of PHA nanocapsules synthesized by a modified precipitation/solvent evaporation technique with neutralization. Specifically, the method comprises the steps of sonicating a first solution comprising a triblock PHA copolymer, stirring the first solution into a second solution to give a third solution, the second solution containing a protein, and the second solution being acidic. Further, the method comprises adding the third solution with a neutralizing agent to give a neutralized solution, and sonicating the neutralized solution to form a final solution, wherein the synthesized PHA nanocapsules containing the protein are formed in the final solution. Further, PHA nanocapsules encapsulated with the protein is used by administering the synthesized PHA nanocapsule to an animal in need thereof via the oral cavity.Type: ApplicationFiled: January 17, 2014Publication date: July 24, 2014Applicant: NANO AND ADVANCED MATERIALS INSTITUTE LIMITEDInventors: Peter Hoi Fu YU, Alex Ho Yin CHAN, Kwok Ping HO
