description	Systems and methods for estimating battery pack capacity during charge sustaining use are provided. 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.
