Abstract:
A battery system includes at least one battery including a plurality of cells and a hybrid control module configured to monitor a differential capacity of the at least one battery, determine when the monitored differential capacity of the at least one battery corresponds to a predetermined differential capacity of the at least one battery, and determine a state of charge of the battery in response to the determination that the monitored differential capacity corresponds to the predetermined differential capacity.
