Abstract

The present invention can provide a strap for compressing outer surfaces of a battery module to prevent deformation of the battery module caused by battery cell swelling, the strap for compressing battery module which has a closed loop structure larger than the outer circumference of the battery module and a welded portion provided in a folded form at at least a portion in the closed loop such that the folded portions overlap with each other when a preset pressure is applied.

Description

technical field [0001] The present disclosure relates to a technique for manufacturing a battery module, and more particularly, to a strap for a battery module, a battery module including the strap, and a jig for compressing the strap. [0002] This application claims priority from Korean Patent Application No. 10-2016-0113289 filed in Korea on Sep. 2, 2016, the disclosure of which is incorporated herein by reference. Background technique [0003] Recently, secondary batteries have been widely used not only for portable devices but also for electric vehicles (EV) or hybrid electric vehicles (HEV) driven by an electric drive source. [0004] Secondary batteries currently widely used include lithium-ion batteries, lithium-polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and nickel-zinc batteries. The operating voltage of a unit secondary battery cell is about 2.5V to 4.2V. Therefore, if a higher output voltage is required, a plurality of secondary...
