Abstract
Provided are a cell screening device for selecting battery cells of a high-risk group, and a cell screening method using the same. According to the present invention, the battery cells may be ordered in the order of high probability of being out of an upper limit value or a lower limit value of an operating voltage among a plurality of battery cells using state information calculated for each battery cell, thereby making it possible to select the battery cells of the high-risk group.
