VEHICLE BATTERY HEALTH DIAGNOSTICS BY ELECTRODE POTENTIAL ESTIMATION

A system and method for diagnosing vehicle battery health using electrode potential estimation is presented. A first set of anode electrode potentials and a first set of cathode electrode potentials of a pristine vehicle battery cell are determined at a first charge rate. A second set of anode electrode potentials and a second set of cathode electrode potentials of a pristine vehicle battery cell are determined at a second charge rate. A determination of a set of optimized health indicators are made based on the first set of anode electrode potentials, the first set of cathode electrode potentials, the second set of anode electrode potentials, and the second set of cathode electrode potentials. Testing a vehicle battery is administered, based on the optimized health indicators, after a first number of cycles to determine a faulty one or more cells of the vehicle battery.
