Abstract: A battery module includes: a plurality of aligned battery cells having differently-oriented surfaces; a cell supervision circuit (CSC) configured to receive signals corresponding to the voltage and/or temperature of at least one of the battery cells; and a flexible interconnector comprising a strip-shaped flexible printed circuit (FPC). The FPC includes a first insulating main surface, a second insulating main surface opposite the first insulating main surface, and a plurality of thermally and/or electrically conducting lines between the first insulating main surface and the second insulating main surface. Each of the conducting lines has a contact portion exposed by a contact aperture in the first insulating main surface and/or in the second insulating main surface and a connecting portion for connection to the CSC, and the flexible interconnector wraps around the battery cells such that the contact portions contact the differently-oriented surfaces of the battery cells.

Abstract: A busbar for a battery module is provided. The battery module includes a plurality of aligned battery cells, and the busbar includes: a busbar body portion extending in an extension direction and a plurality of legs extending from the busbar body portion in a direction non-parallel to the extension direction of the busbar body portion. The busbar body portion have a length to connect cell terminals of a plurality of the battery cells of the battery module, and the legs are configured to electrically connect the busbar body portion and the cell terminals of the battery cells of the battery module to each other.

Abstract: A battery module includes: a plurality of battery cells aligned with each other in an alignment direction; a plurality of busbars; an inlay molded to at least one of the busbars and having a height equal to or less than the at least one busbar; and a top cover on the busbars. Each of the battery cells includes a battery case, an electrode assembly in the battery case, a cap assembly on the battery case, a gas exhaust vent in the cap assembly, and cell terminals protruding over the cap assembly. Each of the busbars electrically connects the cell terminals of a group of the battery cells to each other. The top cover covers the cap assemblies, the busbars, and the inlay, and the busbars and the inlay form a support surface facing towards the top cover to support the top cover.
