Abstract

A battery module may include a plurality of sub-modules arranged in a single direction, a cooling unit contacting one sides of the plurality of sub-modules to cool the plurality of sub-modules, and a heating unit contacting other sides opposing the one sides of the plurality of sub-modules to heat the plurality of sub-modules.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0127366 filed with the Korean Intellectual Property Office on September 9, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates to battery modules. Background technique [0004] In recent years, high-output battery modules having high energy density using non-aqueous electrolyte solutions have been developed. Such a high-output battery module is realized by connecting a plurality of battery cells to each other in series or in parallel to have a high capacity level to be used as a power source for devices requiring high power such as electric vehicles or hybrid vehicles. [0005] The efficiency and performance of a battery module depends on its temperature. For example, when a battery module is discharged at high temperatures, its lifespan is s...
