Abstract
A method for performing SOC calibration for an electrical energy storage system of an electrified vehicle is described The method includes determining a predicted time duration needed to complete a SOC calibration, scheduling a time slot sufficient for completing the SOC-calibration according to the predicted time duration, the scheduled time slot being during a predicted downtime for the electrified vehicle, wherein when at the scheduled time slot: discharging the electrical energy storage system to a steep part of an open circuit voltage versus SOC curve of the electrical energy storage system by an on-board discharge circuit within an acceptable time duration without connecting the electrical energy storage system to a discharging system external to the vehicle; once at an open circuit voltage with gradient with respect to SOC exceeding a threshold indicative of a steep part of the open circuit voltage versus SOC curve, measuring an electrical energy storage system voltage to re-calibrate the SOC of the electrical energy storage system.
