Definitions
- the present invention relates to a battery pack that can effectively suppress the heat propagation phenomenon in which other secondary batteries in the surrounding area are continuously overheated when a thermal runaway phenomenon occurs in one secondary battery.
- secondary batteries can be recharged and have been extensively researched and developed in recent years due to their small size and high capacity.
- Secondary batteries are classified into coin-shaped batteries, cylindrical batteries, square-shaped batteries, and pouch-shaped batteries, depending on the shape of the battery case.
- the electrode assembly mounted inside the battery case in a secondary battery is a power generating element capable of charging and discharging consisting of a stacked structure of electrodes and a separator.
- Patent Document 001 Korean Patent Publication No. 10-2017-0070542 (published on June 22, 2017)
- the purpose of the present invention is to provide a battery pack that can effectively suppress and prevent heat propagation due to thermal runaway occurring in a secondary battery.
- the present invention relates to a battery pack, and in one example, a pack case; a plurality of batteries accommodated inside the pack case; a heat sink located above the battery and storing coolant; and a heat sink and a plurality of supply passages connecting the plurality of batteries, respectively; and a plurality of plugs that respectively seal the plurality of supply passages and are melted by heat generated during thermal runaway of the battery.
