1. A system, comprising:

  • an energy storage device operating according to an operating parameter and comprising a fuel gauge, wherein the fuel gauge;

    receives a different operating parameter in response to a change in the energy storage device charge state; and

    modifies a pulse width modulated signal in response to the change in the energy storage device charge state;

    a detection component coupled to the fuel gauge and an operating system component, wherein the detection component;

    detects the modification of the pulse width modulated signal using a filter; and

    causes the operating system component to generate an interrupt or alarm to update data representing the energy storage device charge state.
