1. A battery pack manufacturing method comprising:
(a) stacking battery cells to form a cell stack;
(b) coupling the cell stack and a U-frame to each other;
(c) measuring a volume of a space bounded in a height dimension by a lower surface of the cell stack and a flat plate coupled to free ends of opposing sidewalls of the U-frame, the space bounded in a width dimension by the opposing sidewalls of the U-frame, and the space bounded in a length dimension by end plates coupled to opposing ends of the U-frame in the length dimension; and
(d) applying an amount of a polymer resin to fill the volume measured in step (c).
