Cell Tab and Interconnect Assembly for a Battery Pack

摘要

A battery pack for a vehicle has battery cells with foil cell tabs that are welded to an interconnect. Nickel plated copper is bonded to aluminum for either a first set of the battery cells, a second set of the battery cells or for the interconnect. Similar materials are then adjacent to each other at the weld locations between the foil cell tabs and the interconnect to avoid welding of dissimilar metals.
