Claim 7:
8. The system of claim 7, wherein the cell connection failure final detector comprises:
a Direct Current Internal Resistance (DCIR) measurer configured to measure DCIR of the battery in a state in which a charging current flows through the battery corresponding to the cell connection failure first detection signal;
a DCIR comparator configured to compare whether the DCIR value measured in the DCIR measurer is out of a predetermined DCIR reference range; and
a connection failure final determiner configured to finally determine that a cell connection failure occurs due to the CID operation or the open parallel connection line in the corresponding battery, and generate and output a cell connection failure final detection signal in response to the DCIR value of the battery corresponding to the cell connection failure first detection signal being out of the predetermined DCIR reference range according to a comparison result of the DCIR comparator.
