Frame structure assembly kit, battery module, and method for manufacturing battery module

A frame structure assembly kit for accommodating a plurality of battery units in a form of a battery module, the kit comprising:

• a bottom frame structure including a plurality of longitudinal bottom frames and a plurality of lateral bottom frames assembled into a grid or ladder, wherein a part of the longitudinal bottom frames and/or the lateral bottom frames bends or extends upward to form at least one guide for determining the position of each battery unit;
• a top frame structure including a plurality of top longitudinal frames and a plurality of top lateral frames assembled into a grid or ladder;
• and
• a plurality of pillars having a length corresponding to the height of the battery units for connecting four corners of the bottom frame structure to the respective four corners of the top frame structure into a rectangular housing capable of accommodating the battery units,
• wherein the bottom longitudinal frame and/or the bottom lateral frame providing the guide are L-shaped angle members, and a vertical portion of the L-shaped angle member constitutes the guide.
