Abstract
An apparatus and a method adapt fuel gauging to a battery chemistry in an electronic device having a battery. The method comprises determining the battery chemistry of the battery and adapting the fuel gauging to the determined battery chemistry. The method can further utilize operational mode information about the electronic device for the fuel gauging. The apparatus comprises a battery monitor and a controller. The controller implements the method. An electronic device having adaptive fuel gauging according to the present invention is also provided. Adapting to battery chemistry can improve the accuracy and efficacy of fuel gauging in the electronic device when the device accepts and operates using any one of a plurality of different battery chemistries.
