Accumulator assembly with an improved welding technique for a cell connector element

摘要

The invention discloses an accumulator arrangement comprising: a first accumulator cell having at least one electrical connection element; - A second accumulator cell with at least one electrical connection element; A cell connector element which electrically connects an electrical connection element of the first accumulator cell and an electrical connection element of the second accumulator cell and which is welded to at least one of the electrical connection elements of one of the accumulator cells by means of a plurality of weld locations, wherein the number and the location of the weld locations depend on a expected current density is selected so that more weld locations are located at locations with a higher expected current density and in places with a lower expected current density no or fewer weld locations are arranged.
