Abstract
An energy storage device includes an integrated fuel gauge that is operatively connected to the energy storage device. The fuel gauge evaluates an operating parameter of the energy storage device and dynamically determines a state of charge. The fuel gauge communicates a communication including a requested operating parameter to the charging component with the single communication line and the signal indicates to an operating system component a change of an energy storage device state. The signal is used to trigger an alert or interrupt that causes the operating system component to display the change of the energy storage state based on the signal.
