  "textContent": "The present invention relates to a device for detecting a crack in a battery cell by using an eddy current, comprising: an inspection unit comprising a first sensor for inducing an eddy current and a second sensor for sensing a signal of the eddy current induced by the first sensor, wherein the inspection unit performs inspection by means of the eddy current while the battery cell is driven; a transfer unit for sequentially transferring a plurality of battery cells from a point where the battery cells are introduced to a point where the battery cells are taken out; and a control unit which is electrically connected to the inspection unit and receives, evaluates, and controls the eddy current signal sensed by the inspection unit. The device for detecting a crack in a battery cell of the present invention can detect the presence and positions of cracks generated on an electrode, an electrode tab, and a welding unit by means of a non-destructive method.",
