Abstract

Disclosed is a battery pack including: a plurality of battery modules each having a plurality of battery cells and a module case for accommodating the plurality of battery cells; an insulating unit interposed between two battery modules facing each other among the plurality of battery modules; and an anti-compression member made of a rigid material and disposed to pass through the insulating unit such that both ends of the anti-compression member are in contact with outer surfaces of the two battery modules facing each other.

Description

technical field [0001] The present disclosure relates to a battery pack including two or more battery modules, and more particularly, to a battery having a heat spread prevention structure that can effectively block heat from spreading to surrounding battery modules when one battery module generates heat Group. [0002] This application claims priority from Korean Patent Application No. 10-2020-0116407 filed in Korea on September 10, 2020, the disclosure of which is incorporated herein by reference Background technique [0003] A semi-permanent battery that converts electrical energy into chemical energy and allows repeated charging and discharging is called a secondary battery, unlike a primary battery that cannot be reused after being used once. [0004] The secondary battery includes a lithium secondary battery, a nickel-cadmium (Ni-Cd) battery, a lead-acid battery, a nickel-metal hydride (Ni-MH) battery, a zinc-air battery, an alkaline manganese battery, and the like. ...
