Module for electrical energy storage assemblies having a flat connecting strip

摘要

The invention relates to a module comprising at least two electrical energy storage assemblies (20), each storage assembly (20) comprising a first face topped by a cover (30) electrically connected to said energy storage assembly (20) and a second face opposite the first face, each cover being in contact with a respective end of a strip (40) in order to electrically connect the two storage assemblies (20), in which the strip (40) and the faces of the covers (30) in contact with the strip (40) are flat, the strip (40) being welded to the faces of the covers (30) along weld leads (50, 50′).

主权项

1. A module comprising at least two electric energy storage assemblies, each electric energy storage assembly comprising a face topped by a cover electrically connected to said electric energy storage assembly, each said cover being in contact with a respective end of a strip in order to electrically connect the at least two electronic energy storage assemblies, wherein each said cover is devoid of an edge extending to an exterior parallel to a revolution axis of the storage assembly, and the strip being welded on the covers in contact with the strip along welding beads and wherein each said electric energy storage assembly comprises a coil element welded to the cover of said electric energy source assembly along at least two welding connections, the welding beads being arranged so as not to overlap the welding connections.
