Abstract: A battery for an electric vehicle includes first and second pairs of modules in electrical communication with each other. The first pair of modules includes a first module and a second module. The second module is in electrical and thermal communication with the first module via a first plurality of outer bus bars. The second pair of modules includes a third module and a fourth module. The fourth module is in electrical and thermal communication with the third module via a second plurality of outer bus bars. The first and second pairs of modules are coupled to each other via a first inner connecting bus bar and a second inner connecting bus bar proximate to a center region of each of the second and third modules.

Abstract: A cooling system for a battery is provided which includes a first tube, a second tube and a middle section which may be formed from an electrically insulating yet thermally conductive material. The first tube and the second tube may each be adapted to transfer coolant from a first end to a second end. The middle section integral may be the first tube on the first side of the middle section and integral to the second tube on the second side of the middle section. The first tube, the second tube and the middle section may be operatively configured to draw thermal energy away from at least one bus bar and corresponding cell tabs for a battery.

Abstract: A lithium ion battery electrode, cell, or module, and a method and apparatus for making the same, is provided. The cell includes a first electrode foil having a first body and a first tab. The first body has long edges defining a length, and short edges defining a width. A length-to-width ratio of the first body is at least two, but may be at least five. The first tab extends from one of the long edges of the first body, and is entirely between one of the short edges of the first body and a midpoint of the long edge. A first coating is formed of one of an anodic material and a cathodic material, and substantially covers and least one side of the first body of the first electrode foil.
