Claim 6:
7. The system of claim 6, wherein the cell connection failure first detector comprises:
a match comparator configured to compare whether a section matching the final connection failure detection reference data exists among actual driving discharge data of the battery monitored by the monitor;
a connection failure first determiner configured to, as a result of the comparison, when there is a section matching the final connection failure detection reference data in the actual driving discharge data, first detect this as a section in which the amount of change in the discharge voltage value occurs due to the CID operation or the open parallel connection line open and determine whether a cell connection failure occurs due to the CID operation or the open parallel connection line open in the corresponding battery; and
a cell connection failure first detection signal generator configured to, in response to the connection failure first determiner first determining that the cell connection failure occurs due to the CID operation or the open parallel connection line in the corresponding battery, generate and output a cell connection failure first detection signal.
