Abstract
Disclosed is a method and system for detecting connection failure of a parallel connection cell, and for a battery that is being discharged by the operation of an external device, by detecting whether there is a section matching the amount of change in the discharge voltage value when a cell connection failure condition occurs due to a pre-prepared current interruption device (CID) operation or an open parallel connection line from the change in the discharge voltage value of the battery being discharged.
