Abstract: An assembly that may include a press that may form an indentation within a tab, a roller assembly including a rolling element that may compress a first tab portion of the tab that extends from the indentation against a busbar, and a welding device that may weld the first tab portion of the tab to the busbar.

Abstract: A thermal management system and a method of operating thereof includes a housing body having a first broad surface and an opposing second broad surface and may extend between a first end and a second end. The housing body defines plural passages disposed between the first and second broad surfaces. The plural passages extend in one or more orthogonal directions between the first and second ends of the body. An inlet conduit is fluidly coupled with a first passage of the plural passages via an inlet structure that defines an inlet of the housing body, and directs a fluid into the first passage of the plural passages. An outlet conduit is fluidly coupled with a second passage of the plural passages via an outlet structure that defines an outlet of the housing body, and directs the fluid out of the second passage of the plural passages.

Abstract: A welding window device includes an elongated body that defines a welding cavity that extends through the body from a top side to a bottom side. The welding cavity is framed by an inlet end, an outlet end, and lateral sides of the body. The body includes one or more gas channels inwardly extending through one or more of the first lateral side or the second lateral side from an inlet opening in the inlet end toward the outlet end of the body. The gas channels include nozzle openings inwardly oriented toward the welding cavity. The gas channels are positioned in the body to direct a gas into the welding cavity during welding of other bodies together within the welding cavity.
