Problems solved by technology

[0004] However, in the case of a conventional battery module, separate fixing members for stacking and fixing a plurality of battery cells and separate cooling members such as cooling pins and cooling plates for cooling the battery cells are also required, so the volume of the battery module Increase
In addition, each side of the module case is formed separately and combined, so the manufacturing process of the module is complicated and the manufacturing time and cost increase

Abstract

The invention relates to a battery module and a manufacturing method thereof. The battery group including a plurality of battery cells stacked with each other; a cooling plate which is located in contact with one side of the battery group to cool the plurality of battery cells; and a case which is located on the other side of the battery group so as to surround the battery group, wherein the casecomprises an upper cover located on the other side of the battery group; and side covers which vertically extend from the upper cover so as to surround side portions of the plurality of battery cellsfrom which electrode tabs protrude.

Description

technical field [0001] The invention relates to a battery module and a manufacturing method thereof. Background technique [0002] With the development of high-tech fields such as digital cameras, mobile phones, notebook computers, hybrid vehicles, etc., rechargeable and dischargeable secondary batteries are being actively researched. The secondary battery may, for example, be a nickel-cadmium battery, a nickel-metal hydride battery, a nickel-hydrogen battery, or a lithium secondary battery. Among them, the working voltage of the lithium secondary battery is above 3.6V, it can be used as a power source of portable electronic equipment or a plurality of lithium secondary batteries can be connected in series for high-power hybrid vehicles, and the working voltage of the lithium secondary battery The voltage is three times higher than nickel-cadmium batteries or nickel-metal hydride batteries, and the energy density characteristics per unit weight are also excellent, so it is ...
