Abstract:
One exemplary embodiment includes a method including providing a battery, producing a first magnetic field so that a second magnetic field is induced in the battery, sensing a magnetic field resulting from the interaction of the first magnetic field and the second magnetic field, utilizing the sensed net magnetic field to determine the state of charge of the battery.
