Abstract:
In some examples, a host device includes a battery capacity and/or battery resistance predictive model. The host device may predict a battery capacity value and/or batter resistance value of a rechargeable battery and compare the predicted battery capacity and/or predicted battery resistance to a battery capacity value and/or battery resistance value stored in a fuel gauge. The host device may overwrite the battery capacity value and/or battery resistance value stored in the fuel gauge with the predicted battery capacity value and/or the predicted battery resistance value if the difference is greater than a maximum error threshold.
