Problems solved by technology

[0003] In addition, the existing battery modules also require separate fixing parts for stacking and fixing a plurality of battery cells, separate cooling parts such as cooling fins and cooling plates for cooling the battery cells, resulting in an increase in the volume of the battery module, and, Since each side of the module case is formed by a separate structure and then combined, there is a problem that the manufacturing process of the module is complicated and the manufacturing time and cost increase

Abstract

The present invention provides a battery module, which includes: a battery group formed by stacking a plurality of battery cells, each of which includes electrode tabs; a cooling housing including a cooling plate located corresponding to one side of sides of the battery group, in which the electrode tabs are not extended, and side plates located on both sides of the battery group perpendicular tothe one side of the sides, thus to house the battery group; a cover plate located on the other side of the battery group; and a front cover part and a rear cover part, which are located at outermost front and rear of the battery group on both sides in a direction in which the electrode tabs are extended.

Description

technical field [0001] Embodiments of the present invention relate to a battery module and a manufacturing method thereof. Background technique [0002] Currently, the research and development of secondary batteries that can be charged and discharged is actively being used in the development of high-tech fields such as digital cameras, mobile phones, notebook computers, and hybrid vehicles. The secondary battery may be a nickel-cadmium battery, a nickel-metal hydride battery, a nickel-hydrogen battery, a lithium secondary battery, or the like. Among them, the operating voltage of the lithium secondary battery is above 3.6V, which is used as a power source for portable electronic devices, or a secondary battery module is formed by connecting a plurality of secondary lithium batteries in series, and is used in a high-output hybrid vehicle, and Compared with nickel-cadmium batteries and nickel-metal hydride batteries, secondary lithium batteries have three times higher operati...
