Abstract
(EN)
A battery module according to one embodiment of the present invention comprises: a cell lamination; a busbar frame assembly including a busbar frame for covering one lengthwise side and the other lengthwise side of the cell lamination and a plurality of busbars, each of which is fixed onto the busbar frame to be electrically connected to a battery cell; and an external terminal connected to the busbar, wherein a pair of electrode leads disposed in the battery cell are formed at a position biased downward from the heightwise center part of the cell lamination, and the external terminal is disposed in a space formed above the electrode leads due to the bias of the electrode leads.
