Abstract
Methods and systems for rerating a battery pack based on fuel gauge data are described, including capturing operational or fuel gauge data for a first battery pack that contains a plurality of battery cells, and determining, based on the fuel gauge data, a remaining capacity of the first battery pack. When the remaining capacity of the first battery pack falls below the minimum capacity; a new battery pack can be configured using some or all of the battery cells, and a second fuel gauge can be configured with new initial capacity and minimum capacity ratings.
