System and method of detecting leakage of battery cell

A method of detecting leakage in a pouch-type battery cell, the method comprising a plurality of steps executable by a controller including:

• determining whether a cell is positioned at a loading position of an input unit configured to transfer the cell to a press unit;
• instructing a loader of the input unit to lift the cell in response to the cell being at the loading position;
• instructing the loader to transport the cell to the measurement position of the press unit in response to the cell being lifted;
• instructing the press unit to press the cell at the measurement position with a preset force in response to the cell being located at the measurement position;
• instructing the measurement unit to measure the insulation resistance of the cell during pressing;
• and
• determining leakage of an electrolyte in the cell on the basis of the measured insulation resistance.

A method of detecting leakage in a pouch-type battery cell, the method comprising:

• pressing the pouch-type battery cell by a press unit;
• measuring insulation resistance of the cell during pressing of the cell by a measurement unit;
• and
• determining leakage of an electrolyte in the cell on the basis of the insulation resistance by a controller configured to communicate with the measurement unit.
