Abstract:
In some aspects, a method of monitoring health of an electrochemical cell can include measuring a first anode voltage at a first anode tab from the plurality of anode tabs and a second anode voltage at a second anode tab from the plurality of anode tabs; measuring a first cathode voltage at a first cathode tab from the plurality of cathode tabs and a second cathode voltage at a second cathode tab from the plurality of cathode tabs; and calculating a first sense voltage, the first sense voltage being a difference between the first cathode voltage and the first anode voltage. In some embodiments, a second sense voltage can be calculated, the second sense voltage being a difference between the second cathode voltage and the second anode voltage. In some embodiments, a difference between the first sense voltage and the second sense voltage can be calculated.
