  • Patent number: 10665910
    Abstract: 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° 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.

  • Patent number: 10340565
    Abstract: Disclosed is a battery cell assembly with improved cooling efficiency. The battery cell assembly includes a cooling fin having a tube through which a coolant flows; at least one frame member; at least one battery cell disposed to face the cooling fin; a first cooling port welded to an inlet formed at one end of the tube of the cooling fin; and a second cooling port welded to an outlet formed at the other end of the tube of the cooling fin. The first cooling port and the second cooling port are made of the same material as the tube.
