BATTERY PACK HAVING OUTSTANDING STRUCTURAL STABILITY

摘要

Provided is a battery pack comprising: a battery-module-arranging body in which 2 or more rows of battery modules are transversely arranged having a structure resulting from the vertical stacking of unit modules housing two or more battery cells or battery cells themselves; a base plate where battery modules are stacked standing vertically; a pair of main members which are respectively positioned against the front surface and the rear surface of the battery-module-arranging body in order to support the weight of the battery modules, and having a structure whereby both end parts are fastened to an external device; a pair of end plates in intimate contact with the front surface and the rear surface of the battery-module-arranging body, in a state in which the bottom ends are secured to the base plate; and a supporting bar which links both sides of the side surfaces or the upper part of the end plates in order to mutually link and support the end plates; wherein the end plates are integrally formed to a size corresponding to the front surface or the rear surface of the battery-module-arranging body so as to be able to minimise deformation of the battery pack in response to vibration in the vertical direction.
