Abstract
Methods and systems for welding contacts of a plurality of battery cells are provided. A method includes using a detector to perform a scan of the cell electrode contact area for each of the plurality of battery cells. Based upon the scan of each cell electrode contact area, a determination is made of whether one or more possible weld sites for each electrode contact area are viable for welding. In response to determining that one or more weld sites are viable, one or more of the viable weld sites are selected and a welder is used to weld at least one of the selected weld sites.
