1. A method for operating an application, the application is selected from one of a mobile communication device, a vehicle, display device, or computing device, the method including a process for monitoring and predicting a state of a battery device while the battery device is configured with the application, comprising:

  • detecting a current and a voltage of the battery device in the application using one or more sensing device coupled to an electronic circuit structure;

    capturing a current value associated with the current and a voltage value associated with the voltage;

    processing the current value and the voltage value;

    determining a state of charge of the battery device using at least a prediction-correction process including the current value and the voltage value, an arbitrary number of representative resistors and capacitors associated with a battery equivalent circuit model, and an unscented transform;

    storing the state of charge in one or more memories;

    outputting the stating of charge; and

    using the state of charge for the application;

    whereupon the unscented filter transform comprises a Gaussian process for selection of more than two Sigma points.
