Battery module assembly having communication terminals of BMS protruding from front thereof

A battery module assembly having unit modules, each of which is configured to have a structure in which unit cells are loaded on a cartridge in a state in which the unit cells are electrically connected to each other via busbars, the battery module assembly comprising:

• two or more sub-modules arranged in a lateral direction while being spaced apart from each other, each of the sub-modules comprising two or more unit modules that are stacked in a height direction from a ground;
• a battery management system (BMS) mounted in a space defined between the sub-modules, the BMS being provided at one side thereof with communication terminals;
• a base plate on which the sub-modules and the BMS are loaded;
• side cover plates mounted at sides of the sub-modules;
• a top cover plate loaded on top surfaces of the sub-modules, the top cover plate being coupled to the sub-modules and to the side cover plates by fastening;
• and
• a front cover plate mounted at fronts of the sub-modules, the front cover plate being coupled to the sub-modules, the base plate, and the side cover plates, the front cover plate being provided with through holes, through which the communication terminals are exposed,
• wherein the sub-modules are connected to each other via a sub-module fastening member, the sub-module fastening member extends between an upper communication terminal and a lower communication terminal of the BMS, and one surface of the BMS at which the sub-module fastening member extends is depressed such that the sub-module fastening member is mounted in the depression.
