A method of operating a battery management system is disclosed. A first voltage drop is sensed between a first terminal of a first battery cell and a second terminal of the first battery cell and a second voltage drop is sensed between a charge distribution pin and the second terminal of the first battery cell. The charge distribution pin is coupled to the first terminal of the first battery cell through a resistor. A difference is calculated between the first voltage drop and the second voltage drop and a faulty condition is detected when Rn absolute value of the difference between the first voltage drop and the second voltage drop exceeds a threshold.
