Busbar for cooling battery cell and battery module using same

Abstract

Disclosed are a busbar for cooling a battery cell and a battery module using the same. A busbar for cooling a battery cell according to an embodiment of the present invention, which is a busbar for cooling a battery cell in a battery module including a plurality of battery cells, comprises: a body portion formed in a shape of a strap and contacting an electrode lead of the battery cell; and a curved portion formed integrally with the body portion and extending from one end of the body portion and curved in the thickness direction of the body portion, wherein the curved portion comprises: a coupling groove coupled to a coupling protrusion provided on a cooling plate of the battery module or a coupling protrusion provided on a predetermined frame of the battery module supporting the busbar;and a thermal contact surface in thermal contact with the cooling plate. Accordingly, an electrode lead portion of the battery cell having a large amount of heat generation is efficiently cooled, thestructure of the battery module is also simplified and miniaturized, and the manufacturing cost is reduced.

Description

technical field [0001] This application claims priority to Korean Patent Application No. 10-2016-0016555 filed in the Korean Patent Office on February 12, 2016, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to a bus bar for cooling a battery cell and a battery module using the same, and more particularly, to a bus bar for cooling a battery cell and a battery module using the same, the bus bar effectively Cools the electrode lead portion of the battery cell that emits a lot of heat and allows structural simplification and size reduction of the battery module. Background technique [0003] Generally, secondary batteries refer to rechargeable and dischargeable batteries, such as lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and the like. [0004] Recently, as secondary batteries are applied to devices requiring high output voltage and larg...

Problems solved by technology

[0005] However, as disclosed in Korean Patent Laid-Open No. 10-2013-0021794 and the like, according to the prior art, since the battery cells are cooled only by the cooling pins, the cooling pins are placed between the stacked battery cells and contact The outer body of the battery cell, that is, the pouch-shaped case of the battery cell, so there is a problem that the electrode lead part of the battery cell that emits a relatively large amount of heat cannot be effectively cooled

[0006] In addition, as disclosed in Korean Patent No. 10-1415050 and the like, according to the prior art, since a large number of cooling pins having a complicated structure are used to improve the cooling performance of the battery module, there is simplification of the structure or size of the battery module. The problem that reduction is difficult and the manufacturing cost of the battery module is increased
