The present invention relates to a method for a non-destructive stiffness inspection of a battery cell and an apparatus therefor. A vibration measurement unit measures a vibration frequency generated when the battery cell vibrates by an operation of a vibration generating unit when the vibration generating unit generates a predetermined degree of vibration to a battery cell to be inspected. A noise removal unit removes a noise signal of the vibration frequency measured in the vibration measurement unit to be outputted to a control unit. After a control unit detects a peak frequency in the vibration frequency where the noise signal inputted through the vibration measurement unit and where the noise removal unit is removed, the control unit confirms stiffness based on the detected peak frequency, and a display unit shows stiffness information of the confirmed battery cell to be inspected and shows a normal status or a malfunctioning status based on the stiffness information. Therefore, the method for a nondestructive stiffness inspection of a battery cell can easily perform a stiffness inspection without directly destroying the battery cell which is required in the prior art and is capable of a total inspection since the method is not the destructive inspection method. Moreover, the method easily performs an additional analyzing work. |
