Abstract

The present invention provides a battery module including: a pair of battery groups in which a plurality of battery cells are stacked; a first heat exchanger disposed between the pair of battery groups to perform heat exchange with first stacked surfaces of the pair of battery groups; and a pair of second heat exchangers disposed outside the pair of battery groups to perform heat exchange with second stacked surfaces which are sides opposite to the first stacked surfaces.

Description

technical field [0001] The present invention relates to a battery module, and more particularly, to a battery module with improved energy efficiency. Background technique [0002] In general, with the development of high-tech fields such as digital cameras, mobile phones, notebook computers, and hybrid vehicles, active research is being conducted on secondary batteries that are chargeable and dischargeable other than primary batteries. Secondary batteries may include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-hydrogen batteries, and lithium secondary batteries. Among them, the working voltage of the lithium secondary battery is 3.6V or more, which can be used as a power source for portable electronic equipment, or for high-power hybrid vehicles by connecting multiple lithium secondary batteries in series. Compared with nickel-cadmium batteries or nickel metal Hydride batteries and lithium secondary batteries have three times higher operating voltages a...
