Abstract: An apparatus is provided for detecting an internal defect of a battery cell. The apparatus may include a time domain reflectometry (TDR) module configured to apply an electrical pulse to the battery cell and compare a reference waveform with a measurement waveform generated by detecting a reflected wave of the electrical pulse to determine whether a defect has occurred, and a signal line configured to electrically connect the TDR module to an electrode lead of the battery cell. The electrical pulse may be applied in a longitudinal direction of the battery cell. A method of detecting an internal defect of a battery cell is also provided.
