SYSTEMS AND METHODS FOR ESTIMATING BATTERY PACK CAPACITY DURING CHARGE SUSTAINING USE

System and methods for estimating a capacity of a battery are presented. In certain embodiments, charge and discharge current throughput data may be separately accumulated during operation of a battery system (e.g., during a charge sustaining operation of vehicle associated with the battery system)....

Zusammenfassung:System and methods for estimating a capacity of a battery are presented. In certain embodiments, charge and discharge current throughput data may be separately accumulated during operation of a battery system (e.g., during a charge sustaining operation of vehicle associated with the battery system). Charge and discharge voltage-based state of charge movement data may be further separately accumulated. Upon accumulating sufficient data, estimated charge and discharge battery capacities may be determined based on the accumulated data.
