Patent number: 8802264Abstract: A weld-free, frameless battery design is provided. The design reduces the number of parts and the weight of the battery pack, simplifies the assembly operation, and keeps the battery pack reparable and remanufacturable with minimal effort and cost. The battery pack includes a stack of battery cells and cooling fins, and a removable restraint is placed around the stack. The positive and negative tabs of the battery cells comprise a pair of sub-tabs which are bent over the faces of the cell. One type of cell can have an extended portion on one of the positive and one the negative sub-tabs which are on opposite faces of the cell. The sub-tabs are used to make the necessary series and parallel connections.Type: GrantFiled: May 6, 2010Date of Patent: August 12, 2014Assignee: GM Global Technology Operations LLCInventors: Yhu-Tin Lin, Andrew H.
