Claim 0:
1. A method for testing a battery pack, the method comprising:
performing a first test on an even-numbered cell of a plurality of cells of the battery pack, the battery pack comprising the plurality of cells, the even-numbered cell comprising a cathode terminal coupled to a even-numbered charge-sensing pin from a plurality of charge-sensing pins through an even-numbered coupling resistor from a plurality of coupling resistors and an anode terminal coupled to an odd-numbered charge-sensing pin from the plurality of charge-sensing pins through an odd-numbered coupling resistor of the plurality of coupling resistors, the cathode terminal being further coupled to an even-numbered charge distribution pin from a plurality of charge distribution pins through a first discharge resistor, the anode terminal being further coupled to a common balance pin, wherein performing the first test comprises:
activating an even-numbered current generator to draw a first current through the even-numbered charge-sensing pin;
calculating a first voltage difference corresponding to the drawn first current and the even-numbered coupling resistor; and
determining a first fault in the battery pack based on the first voltage difference.
