1. A frame structure assembly kit for accommodating a plurality of battery units in a form of a battery module, the frame structure assembly 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 bends or extends upward to form at least two guides 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 a height of the battery units for connecting four corners of the bottom frame structure to respective four corners of the top frame structure into a rectangular housing capable of accommodating the battery units,
wherein the battery unit has a rectangular shape, and the guide determines the position of the battery unit such that a longitudinal direction of each battery unit can be directed parallel to the longitudinal bottom frame,
wherein the bottom frame structure is configured such that the at least two guides that are laterally adjacent are separately placed to define spacer regions, thereby the battery units can be separately mounted from one another onto the bottom frame structure,
wherein the bottom frame structure has bottom air vents just below the spacer regions, and the bottom air vents are defined by the longitudinal bottom frames separately disposed from one another,
wherein the bottom frame structure has through holes formed between adjacent longitudinal bottom frames and between adjacent lateral bottom frames,
wherein the bottom frame structure is configured such that each of the through holes is blocked by the bottom of a battery unit when accommodating the plurality of battery units,
wherein the longitudinal bottom frames defining the spacer region are separated at a first uniform interval, the longitudinal bottom frames forming the though holes are separated at a second uniform interval, and the longitudinal top frames are separated so as to correspond to the first uniform interval and the second uniform interval of the longitudinal bottom frames, and
wherein each of the longitudinal bottom frames is in contact with at least two of the lateral bottom frames.
