Claim 0:
1. A system comprising:
a battery having
an anode;
a cathode;
an electrically insulating separator having a sensing sheet and located between the anode and the cathode, wherein the electrically insulating separator electrically insulates the anode from the cathode, and wherein the sensing sheet includes three or more sensing tabs located at a periphery of the sensing sheet; and
sensing circuitry configured to
electrically connect to each of the three or more sensing tabs,
determine at least one of a resistance, a current, or a voltage at each of the three or more sensing tabs, and
output an indication of the at least one of the resistance, the current, or the voltage at each of the three or more sensing tabs; and

a battery management system communicatively connected to the battery and configured to
receive the output from the sensing circuitry, and
determine a resistance and a two-dimensional position of an internal short on the sensing sheet based on the output from the sensing circuitry.
