BATTERY SECTION BALANCING METHODS AND SYSTEMS

摘要

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.

1. A method for balancing battery states of charge in a multi-sectioned battery, the method comprising the steps of:
determining a state of health of a first section of a multi-sectioned battery; determining a state of health of a second section of a multi-sectioned battery; determining a relationship between a difference between the state of health of the first section and the state of health of the second section and a difference between a state of charge of the first section and a state of charge of the second section after a first time period; receiving a current state of charge of the first section; receiving a current state of charge of the second section; and using the relationship and the current states of charges of the first and second sections to redistribute energy between the first section and the second section in order to reduce a spread between a state of charge of the first section and a state of charge of the second section during use of the multi-sectioned battery.
