Abstract
A battery module of a battery pack of an electric vehicle can include a current collector of a battery, a busbar of the battery and an interface component to electrically couple the current collector and the busbar. The interface component can be electrically coupled with the current collector or be an integral part of a metal layer of the current collector. The interface component can be curved about an edge of the busbar. The interface component can be coupled with the busbar via a first weld at a region of the busbar.
Claims20
A system, comprising:
- a current collector of a battery, the current collector comprising a plurality of layers;
- a busbar of the battery;
- and
- an interface disposed about an edge of the busbar, the interface comprising a portion of a layer of the plurality of layers of the current collector, wherein the portion of the layer of the interface protrudes past the plurality of layers and a surface of the busbar to couple with the busbar via a weld on the surface of the portion of the layer.
A method, comprising:
- providing a current collector of a battery, the current collector comprising a plurality of layers;
- providing a busbar of the battery;
- and
- providing an interface disposed about an edge of the busbar, the interface comprising a portion of a layer of the plurality of layers of the current collector, wherein the portion of the layer of the interface protrudes past the plurality of layers and a surface of the busbar to couple with the busbar via a weld on the surface of the portion of the layer.
