Abstract

An accumulator assembly includes first and second accumulator cells, each of which includes at least one electrical connection element. The accumulator assembly also includes a cell connector element which electrically connects the electrical connection element of the first accumulator cell with the electrical connection element of the second accumulator cell. The cell connector element is welded at least onto one of the electrical connection elements via a plurality of welding locations. The number and the location of the welding locations are selected according to an expected current density in such a way that more welding locations are arranged at locations with a higher expected current density, and zero or fewer welding locations are arranged at locations with a lower expected current density.
