Abstract: The present disclosure relates to a battery module that includes a stack of battery cells, where each battery cell has a terminal, and the terminal has a first alloy of a metal. The battery module has a bus bar that includes a body having a second alloy of the metal, nickel plating on at least a portion of the body, and an indentation disposed on the body, where a thickness of the nickel plating is between 0.2% and 20% of an overall thickness of the body, and a weld physically and electrically coupling the respective terminal to the bus bar. The indentation has a depth between 10% and 90% of the overall thickness, an area of the indentation is between 5% and 20% of an overall area of the body, and the nickel plating enables the weld to be stronger than a weld between the first and second alloys.

Abstract: The present disclosure includes a battery module having a housing with a first end (having a cell receptacle region) and a second end opposite to the first end. The battery module includes a stack of electrochemical cells inserted through the cell receptacle region of the housing, disposed between the first end and the second end of the housing, and having terminal ends of all the electrochemical cells of the stack aligned in a planar area. The battery module includes a bus bar carrier disposed over the stack of electrochemical cells and within the cell receptacle region of the housing. The bus bar carrier includes bus bars disposed thereon that interface with the terminal ends. The battery module includes a layer of thermal epoxy disposed between the second end of the housing and a bottom side of the stack of electrochemical cells.
