Abstract: Provided are interconnects for interconnecting a set of battery cells, assemblies comprising these interconnects, methods of forming such interconnects, and methods of forming such assemblies. An interconnect includes a conductor comprising two portions electrically isolated from each other. At least one portion may include two contacts for connecting to battery cells and a fuse forming an electrical connection between these two contacts. The interconnect may also include an insulator adhered to the conductor and mechanically supporting the two portions of the conductor. The insulator may include an opening such that the fuse overlaps with this opening, and the opening does not interfere with the operation of the fuse. In some embodiments, the fuse may not directly interface with any other structures. Furthermore, the interconnect may include a temporary substrate adhered to the insulator such that the insulator is disposed between the temporary substrate and the conductor.

Abstract: Provided are interconnect circuits for combined electrical and thermal energy transfer to devices connected to these circuits. Also provided are methods of fabricating such interconnect circuits. An interconnect circuit may include an electro-thermal conductor and at least one insulator providing support to different portions of the conductor with respect to each other. The insulator may include one or more openings for electrical connections and/or heat exchange with the electro-thermal conductor. The portions of the conductor may be electrically isolated from each other in the final circuit. Initially, these portions may be formed from the same conductive sheet, such as a metal foil having a thickness of at least about 50 micrometers. This thickness ensures sufficient thermal transfer in addition to providing excellent electrical conductance. In some embodiments, the conductor may include a surface coating to protect its base material from oxidation, enhancing electrical connections, and/or other purposes.

Abstract: Provided are electrical harness assemblies and methods of forming such harness assemblies. A harness assembly comprises a conductor trace, comprising a conductor lead with a width-to-thickness ratio of at least 2. This ratio provides for a lower thickness profile and enhances heat transfer from the harness to the environment. In some examples, a conductor trace may be formed from a thin sheet of metal. The same sheet may be used to form other components of the harness. The conductor trace also comprises a connecting end, monolithic with the conductor lead. The width-to-thickness ratio of the connecting end may be less than that of the conductor trace, allowing for the connecting end to be directly mechanically and electrically connected to a connector of the harness assembly. The connecting end may be folded, shaped, slit-rearranged, and the like to reduce its width-to-thickness ratio, which may be close to 1.
