Abstract: A measurement fixture for a battery cell is provided when the battery cell is connected to an apparatus. The measurement fixture comprises a chamber, a pressure sensor and an expansion sensor. The chamber defines a sealed space for receiving the battery cell. The pressure sensor is mounted to the chamber to sense a change of pressure in the sealed space due to a volume change of the battery cell to calculate pressure in the battery cell and the volume change of the battery cell non-contactly. The expansion sensor is mounted to the chamber to sense a deformation of the battery cell to calculate a correlation between the pressure in the battery cell and the volume change of the battery cell non-contactly.
