Document Type and Number:
WIPO Patent Application WO/2011/096677
Kind Code:
A2
Abstract:
The present invention provides a battery pack comprising: a battery module array having at least two columns of battery modules arranged on the side, with each battery module having a structure where unit modules with built-in battery cells themselves or at least two battery cells are stacked up in the vertical direction; a base plate on which the battery modules are set up in the vertical direction; a pair of main members disposed respectively at the front and rear sides of the battery module array to support the load of the battery modules, with both ends of the main member being fastened to an external device; a pair of end plates adhered respectively to the front and rear sides of the battery module array, with the lower end being fixed to the base plate; and a supporting bar for connecting the top or side of both end plates to interconnect and support the end plates. Furthermore, on the outer side of the outermost battery module of the battery module array there is a reinforcing member being coupled to the side wall of the end plate or to the side of the main member so as to minimize the transformation of the battery pack against vibration in the back-and-forth direction.
