Abstract

A battery module according to one embodiment of the present invention comprises: a plurality of battery cells; a module case that accommodates a cell stack, the cell stack including the plurality of battery cells; a sprayer passing through the module housing from one side in a stacking direction of the cell stack; and a thermal expansion block disposed in the hollow space in the module case to thermally expand according to a temperature increase in the interior of the module case.

Description

technical field [0001] The present disclosure relates to a battery module having a structure allowing rapid cooling and an ESS including the battery module. More particularly, the present disclosure relates to a battery module and an ESS including the battery module having a structure capable of rapidly increasing the energy for Level of cooling fluid (eg, cooling water) for extinguishing and cooling. [0002] This application claims priority from Korean Patent Application No. 10-2020-0024462 filed in Korea on February 27, 2020, the disclosure of which is incorporated herein by reference. Background technique [0003] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, and lithium secondary batteries. Among them, lithium secondary batteries have attracted attention because they have almost no memory effect compared to nickel-based secondary batteries, thereby ensuring free charge and discharge, an...
