Abstract: Methods and systems for balancing battery states of charge in a multi-sectioned battery. In some embodiments, states of health and states of charge of one or more sections of a multi-sectioned battery may be determined. A relationship between the states of charge and states of health of the battery sections may be determined. This information may be used apply a balancing algorithm to redistribute energy between the various battery sections in order to reduce a spread between the states of charge due to the varying states of health.
