Battery module with cooling structure of high efficiency

摘要

Disclosed herein is a battery module including chargeable and dischargeable battery cells which are sequentially arranged in a stacked state, cartridges fixing edges of the respective battery cells to form a battery cell stacked structure, and heat transfer members mounted between the respective battery cells, edges of the heat transfer members being partially or entirely fixed to the respective cartridges. The battery module according to the present invention is configured to have a structure in which the heat transfer members, to which heat generated from the battery cells is conducted, are coupled to the cartridges to fix the battery cells and, at the same time, to cool the battery cells, thereby improving cooling efficiency, reducing the size of the battery module to have a compact structure, and improving structural stability of the battery cells.

1. A battery module comprising:
chargeable and dischargeable battery cells which are sequentially arranged in a stacked state; cartridges fixing edges of the respective battery cells to form a battery cell stacked structure; cooling members mounted to the outsides of the cartridges; and heat transfer members mounted between the respective battery cells, edges of the heat transfer members being partially or entirely fixed to the respective cartridges, wherein ends of each of the heat transfer members extend through a corresponding one of the cartridges such that the ends of each of the heat transfer members are exposed to an outside of the corresponding cartridge, wherein the ends of each of the heat transfer members exposed to the outside of the corresponding cartridge are bent such that the exposed ends of each of the heat transfer members tightly contact the outside of the corresponding cartridge, wherein each of the battery cells is a lithium secondary battery, and wherein the ends of the heat transfer members contact the cooling members.
