Embodiment Construction

[0034] Embodiments are directed to battery packs with interlocking features. Aspects are illustrated in connection with one possible system and method, but the detailed description is intended as an example only. exist Figure 1-5 Embodiments are shown in , but the embodiments are not limited to the illustrated structures or applications. It will be appreciated that, where appropriate, reference numerals have been repeated among the different figures to indicate like elements for simplicity and clarity of illustration.

[0035] A battery assembly may include multiple subassemblies. refer to figure 1 , an exploded view of an example of a subassembly 100 is shown. In one arrangement, the subassembly 100 may include a unit support, a first frame 110 and a second frame 130 . The first frame 110 and the second frame 130 are placed on opposite sides of the unit support. In one embodiment, the cell support may be a heat sink 120 that may dissipate heat generated by the battery ...

Abstract

A battery cell assembly includes a plurality of sub-assemblies. Each sub-assembly includes a heat sink and a first frame and a second frame disposed on opposite sides of the heat sink. The sub-assemblies are stacked to form a plurality of cell pockets that receive a battery cell. The battery cell assembly further includes a plurality of tie rods for fixing the plurality of sub-assemblies together. The first frame is formed with a plurality of through holes, and the second frame is formed with a plurality of protrusions with a hole extending therethrough. The frames are brought together such that each protrusion is at least partially received in a respective through hole. The interior surfaces of corresponding protrusions and through holes of the stack of frames form a passage for one of the tie rods to extend through.

Description

[0001] Cross References to Related Applications [0002] This application is related to US Patent Application Serial No. 12 / 843,667, filed July 26, 2010, entitled "BATTERY CELL SYSTEM WITH INTERCONNECTED FRAMES," the contents of which are expressly incorporated herein by reference. technical field [0003] Embodiments relate generally to batteries, and more particularly to multi-cell battery systems. Background technique [0004] A battery is a device that converts chemical energy directly into electrical energy. In some applications, multiple cells, such as lithium cells, are assembled together to form a battery cell assembly to provide sufficient power for different applications. To assemble multiple battery cells, the cells are arranged in stacks together with a generally planar frame. Portions of the battery cells are sandwiched between the battery frames. Tie rods can be used to hold the stack of battery cells together under slight compression. Each tie rod can exte...
