Abstract:
1. A battery module constructed in a structure in which a plurality of plate-shaped secondary battery cells, which can be charged and discharged, are sequentially stacked on a lower plate, and an upper plate is coupled to an uppermost of the battery cells, wherein the plates are provided at (i) a top and a bottom thereof or (ii) a right side and a left sides thereof, or (iii) the top, the bottom, the right and left sides with a sliding coupling structure, and wherein the battery module comprises: a rectangular lower case including an upper end receiving part in which the battery cells are sequentially stacked; a rectangular upper case including a lower end receiving part for covering the battery cells stacked on the lower case; a first circuit unit for electrically connecting the stacked battery cells to each other, the first circuit unit including a sensing board assembly for detecting voltage and/or current of the battery cells; a second circuit unit electrically connected to the first circuit unit, the second circuit unit including a main board assembly for controlling overall operation of the battery module; and a third circuit unit electrically connected to the second circuit unit, the third circuit unit connected to an external output terminal while preventing an overcurrent.
