Problems solved by technology
[0010] When a fire or thermal runaway occurs in any one of a plurality of battery packs, the fire is suppressed by supplying a fire extinguishing agent to the battery pack where the fire or thermal runaway occurred, but the fire extinguishing agent is supplied to the battery pack where the fire did not occur , so the corresponding battery pack is contaminated by the extinguishing agent and cannot be reused

The present invention provides a battery rack capable of effectively preventing the spread of fire or heat and recovering an undamaged battery pack. To achieve the above object, the battery rack according to the present invention comprises: a plurality of battery packs vertically arranged, each of the battery packs comprising a plurality of secondary batteries stacked in one direction, and a battery pack case having an internal space formed therein, a battery pack case to receive the plurality of secondary batteries, and configured to enable a fire extinguishing agent to be supplied to the inside thereof when a temperature therein rises to a predetermined temperature or higher; and a battery rack case having a receiving space into which the plurality of battery packs can be received, and including a plurality of rack plates each having a mounting surface on which the battery packs are mounted and which is inclined at a predetermined angle, and an extension portion extending from the mounting surface to the mounting surface. And an extension portion disposed on the mounting surface such that a height of the mounting surface gradually decreases in one direction, the extension portion having an end portion facing the one direction, the end portion protruding further in an outward direction than the battery pack located below.
Description
technical field [0001] The present disclosure relates to a battery rack and an energy storage system including the battery rack, and more particularly, the present disclosure relates to a battery rack for effectively preventing fire or heat from spreading when a fire or thermal runaway occurs during use, And reuse undamaged battery packs. [0002] This application claims priority from Korean Patent Application No. 10-2020-0027372 filed with the Korean Intellectual Property Office on March 4, 2020, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] At present, commercially available secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries, etc. Among them, lithium secondary batteries have little or no memory effect, so compared with nickel-based secondary batteries , Lithium secondary batteries are attracting more and more attention because they ...
