Abstract
A method for connecting a flexible printed circuit (FPC) to a battery module and a cell supervision circuit board (CSCB) is provided. The method includes: providing a coil of a continuous, strip-shaped FPC; unwinding a first section of the FPC from the coil, positioning the first section of the FPC over a first contact portion of the battery module, and welding a conductive structure of the FPC in the first section to the first contact portion of the battery module; unwinding a second section of the FPC from the coil, positioning the second section of the FPC over a contact pad of the CSCB, and welding the conductive structure of the FPC in the second section to the contact pad of the CSCB; and separating the first section and second section of the FPC from the coil of the FPC.
Claims4
A tool for connecting a flexible printed circuit (FPC) to a battery module, the tool comprising:
- a tool head comprising a coil holder configured to receive a coil of a continuous and strip-shaped FPC and an optical sensor configured to detect a position of the unrolled FPC,
- wherein the tool head is configured to perform translational movement in an area parallel to a contact portion of the battery module and a contact pad of a cell supervision circuit board (CSCB) and to perform translational movement in a direction parallel to normal vectors of the contact portions and the contact pad of the CSCB, and
- wherein the tool head is configured to weld a conductive structure of the FPC with the contact portion and the contact pad of the CSCB.
