摘要： A modular battery pack and method of making a battery pack. Prismatic can battery cells are interspersed with cooling frames along a stacking axis within a housing such that numerous a cell-frame assemblies, each with a cooling path, are formed. Resiliently-biased sealing members on the frames are arranged such that they remain out of the way of a footprint defined by the joined cells and frames to promote ease of high-speed cell-to-frame assembly. Upon formation of the cell-frame assembly and subsequent placement into the housing with inner walls that press against the protruding ends of the sealing member, the sealing member is forced by the housing to come into contact engagement with a corresponding surface of the edge of the battery cell. The generally linear, planar contact surface formed by the contact engagement promotes the formation of a sealing surface that makes it harder for introduced cooling air to escape. By this sealing member construction, cell-frame assemblies may be produced with high-speed automated assembly techniques that may have both large manufacturing tolerances prior to assembly and substantially gap-free cell-to-cooling frame contacting surfaces after assembly.

摘要： A multi-tasking end effector system includes a base frame connected to a robot arm of a robot. A first shaft is rotatably supported on the base frame. A first pin-wheel assembly is rotatably mounted to the shaft at a first end of the base frame. Multiple first die assemblies are mounted to the first pin-wheel assembly. A second pin-wheel assembly is rotatably mounted to the shaft at a second end of the base frame. Multiple second die assemblies are mounted to the second pin-wheel assembly and individually oriented in mirror image configuration to one of the multiple first die assemblies. An index motor rotates the first shaft and co-rotates paired and mirror image die assemblies. First and second tab-bending actuators mounted to the base frame are operated to bend opposed cell tabs of a battery cell positioned between the first and second pin-wheel assemblies.

摘要翻译： 模块化电池组和制造电池组的方法。 棱柱形电池单元沿着壳体内的堆叠轴线散布有冷却框架，使得形成多个具有冷却路径的电池框架组件。 框架上的弹性偏置的密封构件被布置成使得它们保持在由连接的单元和框架限定的覆盖物的方式之外，以促进高速单元到框架组装的容易性。 在形成电池框架组件并随后将其放置在具有压靠密封构件的突出端的内壁的壳体中时，密封构件被壳体强制地与所述密封构件的边缘的相应表面接触接合 电池单元 通过接触接合形成的大致线性的平面接触表面促进形成密封表面，这使得引入的冷却空气更难以逸出。 通过该密封构件结构，电池框架组件可以使用高速自动组装技术来生产，其可以在组装之前具有大的制造公差，并且在组装之后具有基本无间隙的电池与冷却框架接触表面。
