BATTERY PACK SYSTEM WITH END-PLATES FOR INTERNAL PRESSURE DISTRIBUTION

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.
