Abstract
A disconnection identification device according to one embodiment disclosed in the present document identifies whether a fuse disposed on a charging / discharging line connected to a battery cell included in a battery pack is disconnected, and may comprise: a first FET connected to the fuse through a reference node, a first node and a second node, and connected to the fuse through the first node; a second FET connected to the fuse through the second node; and an IC chip for identifying, on the basis of an operation state of at least one of the first FET and the second FET, whether the fuse is disconnected.
