Abstract

Embodiments are directed to a contact plate configured to establish electrical bonds between battery cells in a battery module. In a first embodiment, the contact plate includes at least one primary conductive layer, wherein the contact plate is configured to exchange current with at least one group of battery cells in the battery module, and wherein a thickness of the at least one primary conductive layer scales with a current expectation at different portions of the contact plate. In a second embodiment, the contact plate includes at least one primary conductive layer, and a set of bonding connectors that is configured to provide direct electrical bonds between the contact plate and terminals of at least one group of battery cells, wherein the set of bonding connectors is pre-assembled with the contact plate before the contact plate is installed into the battery module.
