Abstract

A dark current detection apparatus, a battery management system, and a battery pack, having a circuit topology capable of detecting an increase in dark current due to the loss of a dark current blocking function of a dark current blocking element. A dark current detection apparatus can include a voltage monitoring circuit that outputs a voltage monitoring signal having a variable magnitude, the variable magnitude varying according to a monitoring voltage of a monitoring node connected to the dark current blocking element, and a processor that determines whether the dark current occurs based on the voltage monitoring signal output from the voltage monitoring circuit.
