A battery module includes a plurality of battery cells stacked on one another and respectively having electrode leads protruding on at least one side thereof and a bus bar assembly configured to electrically connect the electrode leads of the plurality of battery cells and having at least one lead slot through which electrode leads of two battery cells adjacent to each other pass in common.

Battery module, battery pack comprising battery module, and vehicle comprising battery pack

Disclosed is a battery pack using a direct cooling method on the edge surface of a battery. The direct cooling-type battery pack, which is prevented from leakage caused by swelling through a cooling surface formed on an edge surface of a battery cell and is applicable to a bi-directional cell, includes: a battery module having a plurality of battery cells stacked therein; a cooling frame corresponding to a casing in which the battery module is received, and forming a cooling surface on an edge surface in a direction of 90&#xb0; from a stacking surface on which the battery cells are stacked; and a heat sink which is positioned at the bottom of the cooling surface, is coupled with a cooling frame enclosing the battery module and mounted to the upper part thereof, stores a coolant therein, and supplies the stored coolant to the cooling surface. According to the present disclosure, a direct cooling-type cooling surface is formed on one edge surface of a battery pack to prevent leakage of a coolant caused by swelling and to provide a battery pack applicable to a bi-directional cell.
