BATTERY STATE ESTIMATION BASED ON MULTIPLE RATES OF HYSTERESIS TRANSIT

A system for an electric vehicle includes a hysteresis module configured to calculate a plurality of hysteresis state components of a battery based on a measured current and a respective hysteresis transit rate, calculate an overall hysteresis state of the battery based on the plurality of hysteresi...

Zusammenfassung:A system for an electric vehicle includes a hysteresis module configured to calculate a plurality of hysteresis state components of a battery based on a measured current and a respective hysteresis transit rate, calculate an overall hysteresis state of the battery based on the plurality of hysteresis state components, and calculate a hysteresis voltage of the battery based on the overall hysteresis state, and a state of charge (SOC) module configured to calculate an SOC of the battery based in part on the hysteresis voltage.
