ABSTRACT:
Full capacity determination in a battery gas gauge. Operations include measuring instantaneous open circuit voltage levels during an open circuit time interval for a specific battery cell and correlating such measurements to estimate values. Such estimated values may then be correlated to associated relative state of charge levels. Finally, a full capacity calculation can be made based on the associated relative state of charge levels. A plurality of full capacity determinations may also be made and compared to each other to assess the reliability of such determinations.
