Claim 20:
21. The control device of claim 17, wherein the control device is configured to perform a second test on an odd-numbered cell of the plurality of cells, the odd-numbered cell comprising a cathode terminal coupled to the odd-numbered charge-sensing pin through the odd-numbered coupling resistor and an anode terminal coupled to a preceding even-numbered charge-sensing pin from the plurality of charge-sensing pins, the anode terminal being further coupled to the common balance pin, wherein the control device is configured to perform the second test by:
activating an odd-numbered current generator to draw a second current through the odd-numbered charge-sensing pin;
calculating a second voltage difference corresponding to the drawn second current and the odd-numbered coupling resistor; and
determining a second fault in the battery pack based on the second voltage difference.
