Beschreibung
Zusammenfassung:	The invention relates to a battery pack box body and a preparation method, the battery pack box body comprises a bottom plate, the surface of the bottom plate is provided with first net-shaped reinforcing ribs; the frame assembly is connected to the edge of the bottom plate, a containing cavity used for containing a battery module is defined by the frame assembly and the bottom plate, and a second net-shaped reinforcing rib is arranged on the outer wall of at least one side of the frame assembly; the bottom plate, the first net-shaped reinforcing ribs, the frame assembly and the second net-shaped reinforcing ribs are integrally formed in a casting mode. Besides, according to the battery pack box body, the bottom plate, the first net-shaped reinforcing ribs, the frame assembly and the second net-shaped reinforcing ribs are integrally cast and formed, so that integral forming design is realized, welding deformation caused by welding manufacturing forming is avoided, and compared with a battery pack box body in
