Abstract
An embodiment is directed to a multi-layer contact plate configured to establish electrical bonds to battery cells in a battery module. The multi-layer contact plate includes two or more primary conductive layers (e.g., Al, Cu, etc.), and a cell terminal connection layer (e.g., steel, Al, Cu, etc.) that is joined with, and sandwiched by, the two or more primary conductive layers. A portion of the cell terminal connection layer is configured to form a set of bonding connectors (e.g., bonding ribbons) to provide a direct electrical bond between the multi-layer contact plate and terminals (e.g., positive terminals, negative terminals, or a combination thereof) of at least one group of battery cells (e.g., a single group of battery cells, two groups of battery cells that are connected in series, etc.).
