    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 relates generally to a welding process for a battery module. In an embodiment, a system for welding two components in a battery module includes a laser source configured to emit a laser beam onto a workpiece having a first battery module component and a second battery module component. The system also has an actuator coupled to the laser source and configured to move the laser beam along a first axis and a second axis and a controller electrically coupled to the laser source and the actuator. The controller is configured to send a signal to the laser source and the actuator to form a sinusoidal lap weld on a surface of the workpiece, such that the first battery module component is electrically coupled to the second battery module component.

    Abstract: A battery module includes a housing and battery cells disposed in the housing, each of the battery cells including two terminals. The battery module also includes bus bar cell interconnects including a first material, where each bus bar cell interconnect is configured to electrically couple two adjacent battery cells via an electrical coupling with a first terminal of one of the adjacent battery cells and a second terminal of the other adjacent battery cell, where at least one of the first and second terminals includes the first material. The battery module includes welds, each weld being disposed at a corresponding welding point to directly couple one of the bus bar cell interconnects with the corresponding at least one terminal including the first material. Each welding point is accessible for welding from a position above the battery cells when the interconnects are disposed over the battery cells.
