Definitions
- the present invention relates to a battery pack, and more particularly, to a battery pack including a connecting cooling member extending integrally over an outer surface of one end of a battery cell and an electrode.
- Battery modules or battery packs used in electric vehicles are composed of a number of battery cells. Accordingly, the function of effectively cooling the heat generated from the battery cells is important.
- Traditional cooling methods include the Bottom Cooling method, which cools the bottom of the battery cell, and the Side Cooling method, which cools the side of the battery cell.
- Battery cells used in electric vehicles, etc. are becoming larger. When cylindrical battery cells are applied, the larger battery cell size means that the diameter and height of the battery cell increase. As battery cells become larger, the Bottom Cooling method has limitations in achieving the cooling goal. Accordingly, the Side Cooling method, which cools the side of the battery cell, is gaining attention. For example, Tesla automobiles are using the Side Cooling method to cool the battery cell.
- the cooling pipe itself is placed on the side of the battery cell.
- the material cost and process configuration cost of the parts for forming the cooling structure increase.
- the thickness of the cooling pipe must be secured, there is a problem that the efficiency of space utilization is reduced.
- the purpose of the present invention is to solve the problems described above, and to provide a battery pack in which cooling performance is improved, space utilization is optimized, and material costs are reduced by improving the side cooling structure of a battery cell.
- a battery pack according to the present embodiment comprises a battery cell including an electrode formed at one end and an outer surface extending between the one end and the other end;
- It comprises a connecting cooling member that extends integrally on one end of the electrode and the outer surface of the battery cell,
- the above-mentioned connecting cooling member is characterized in that it is made of a first metal.
- the battery pack according to the present invention includes a connecting cooling member that is integrally extended from one end of an electrode of a battery cell and an outer surface thereof with the same first metal material, so that heat generated from the side of the battery cell quickly moves to the upper or lower part of the battery cell through the connecting cooling member, thereby improving the cooling performance of the battery cell.
- the connecting cooling member also functions as a bus bar, thereby providing the effects of increasing space efficiency and reducing material and process costs.
