Abstract: A battery pack system features a base plate, transverse members, and at least three upward-extending longitudinal members that partition the base plate's surface into a lattice. Battery modules containing battery cells are installed in the resulting lattice-shaped spaces and coupled to seating portions at each intersection. Each longitudinal member includes a surface pressure block positioned between two fixing units, pushing the modules on both sides toward these fixing units for secure retention.

Abstract: A battery pack system includes a plurality of battery modules with stacked battery cells. The plurality of battery modules is secured to multiple seating portions in a battery housing. The housing includes a base plate forming its bottom surface, from which multiple transverse members protrude upward, running parallel to each other. A set of longitudinal members intersects these transverse members, creating defined seating portions. Two end-plates are connected to the transverse members, forming parallel side walls. The distance between the end-plates'facing pressing surfaces is precisely adjusted and fixed.
