Abstract

See full text

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.
