摘要： An interconnection for a battery comprising a plurality of cells having connection tabs. The interconnection comprises a first electrically insulating substrate, a heat sink, a plurality of tab-receiving regions, a plurality of aperture and electrically insulating material. The first electrically insulating substrate has a first face on a first side of the interconnection and a second face. The heat sink is thermally connected to the second face of the first substrate. The plurality of tab-receiving regions comprise electrically conducting material on the first side of the interconnection for receiving connection tabs of the cells. The plurality of apertures extend through the interconnection, wherein the apertures are arranged to allow connection tabs of the cells to extend from a second side of the interconnection, through the apertures, and to the first side of the interconnection for establishing contact with the tab-receiving regions on the first side of the interconnection. The electrically insulating material is arranged to insulate the apertures from the heat sink, such that connection tabs extending through the apertures are electrically insulated from the heat sink.
