Claim 2:
3. The method of claim 1, wherein the reference data acquisition step further comprises:
a first connection failure reference detection data acquisition step of summing the acquired driving discharge reference data and connection failure time point reference data for a same time interval and first acquiring data on a change in the discharge voltage value in the CID operation or the open area of a parallel connection line; and
a final connection failure detection reference data acquisition step of repeating the driving discharge reference data acquisition step, the connection failure time point reference data acquisition step, and the first connection failure detection reference data acquisition step a predetermined number of times and by applying a machine learning technique to the plurality of first connection failure detection reference data obtained and finally acquiring data on the amount of change in the discharge voltage value in the CID operation or the parallel connection line open area.
