Abstract

The present invention relates to a method for manufacturing a battery pack, comprising the steps of: (a) stacking battery cells to form a cell stack; (b) combining the cell stack and a U-frame; (c) measuring the volume of a space between a flat plate and the cell stack in combination with the U-frame; and (d) applying as much polymer resin as the volume measured in step (c).

Description

technical field [0001] This application claims the benefit of priority from Korean Patent Application No. 2019-0003263 filed on January 10, 2019, the disclosure of which is hereby incorporated by reference in its entirety. [0002] The present invention relates to a method of manufacturing a battery pack, and more particularly, the present invention relates to a method of manufacturing a battery pack comprising measuring the temperature of an appropriate amount of a polymer resin used as a thermal conductor between a battery cell and a battery case. process. Background technique [0003] In recent years, secondary batteries capable of charging and discharging have been widely used as energy sources for wireless mobile devices. In addition, secondary batteries are also attracting attention as power sources for electric vehicles (EV), hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (Plug-In HEV). Hybrid vehicles have been proposed as a solution to air pol...
