Abstract

The present invention relates to a battery module, a battery pack including the same, and an energy storage system including the battery pack to reduce the risk of secondary combustion or explosion and enhance durability against external impact. The battery module comprises: a plurality of secondary batteries arranged in two rows in the front and rear directions, each of the plurality of secondarybatteries comprising a gas venting unit for discharging a gas generated inside to the outside at a predetermined pressure; and a cooling member comprising a main body part provided between the two rows of the plurality of secondary batteries and having a size corresponding to the side parts in the left and right directions of the plurality of secondary batteries, and a gas discharge unit providedat at least one of the upper portion and the lower portion of the main body part and having a gas discharge path elongated from the front end to the rear end of the main body part.

Description

technical field [0001] This application claims priority to Korean Patent Application No. 10-2019-0071732 filed in Korea on June 17, 2019, the disclosure of which is incorporated herein by reference. [0002] The present disclosure relates to a battery module including a cooling member, a battery pack including the battery module, and an energy storage system including the battery pack, and more particularly, the present disclosure relates to a battery module that reduces afterburning or risk of explosion and increase durability against external shocks. Background technique [0003] Currently commercially available secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries, and the like. Among these batteries, compared with nickel-based secondary batteries, lithium secondary batteries have advantages such as free charge and discharge due to substantially no memory effect, extremely low self-discharge ra...
