Claim Text:
1. A method, comprising: receiving, by a processor, voltage values corresponding to a battery system; receiving, by the processor, charge values corresponding to charge flowing through the battery system; analyzing, by the processor, at least the received voltage values over at least one defined duration period of time; determining, by the processor, anchoring points of charge integration that satisfy respective defined conditions for respective defined duration periods of time by a defined quantity of repetition of conditions based at least in part on the received voltage and time, wherein the defined quantity of repetition is greater than 1; updating, by the processor, a capacity of the battery system by assigning the determined anchoring points that satisfy the respective defined conditions as updated anchoring points of the charge integration thereby replacing values of previously assigned anchoring points; and determining, by the processor, a state of charge based on the updated anchoring points of the charge integration.
