Abstract
A manufacturing process flow and accompanying methods for assembling a battery module are designed to increase efficiency, reduce a footprint of the manufacturing process, reduce manufacturing time, allow for increased flexibility, and reduce costs. The process flow takes advantage of robotic functionality to combine multiple manufacturing and quality assurance operations.
Claims13
A method for assembly of a battery module, comprising:
- obtaining a battery module shell;
- placing a plurality of battery cells in the battery module shell;
- electrically coupling the battery cells;
- and
- electrically coupling a control circuit to the battery cells wherein electrically coupling the battery cells comprises coupling a single flexible circuit to all of the plurality of battery cells;
- wherein each of the plurality of battery cells comprises a positive electrode and a negative electrode, and coupling the flexible circuit to the plurality of battery cells comprises coupling the flexible circuit to each positive electrode and each negative electrode;
- and
- wherein the plurality of battery cells are arranged in rows, and the flexible circuit is coupled to each positive electrode and each negative electrode in each row simultaneously.

A method for assembly of a battery module, comprising:
- obtaining a battery module shell for containing battery cells, the module shell having a retainer plate with rows of openings adapted to at least partially receive battery cells therein;
- arranging battery cells into rows corresponding to the rows of openings in the retainer plate;
- robotically grasping at least one row of battery cells and placing the battery cells into at least one row of openings in the retainer plate while simultaneously electrically testing each battery cell;
- electrically coupling the battery cells in the module shell;
- electrically coupling a control circuit to the battery cells;
- coupling each of the battery cells to the retainer plate;
- and
- coating at least a portion of each opening in the retainer plate with an adhesive accelerator prior to placing the battery cells into the openings,
- wherein coupling each of the battery cells to the retainer plate comprises placing an adhesive on each of the battery cells prior to placing the battery cells into the openings in the retainer plate.
