1. A method for monitoring characteristics of an electric energy device, comprising:
generating at least two external shorts with known current or voltage profiles at the electric energy device;
sensing at least one change in an electromagnetic field emitted by the electric energy device due to the generated at least two external shorts by at least one sensor at a predetermined distance from the device;
determining at least one signal parameter based on the sensed at least one change in electromagnetic field in the vicinity of the electric energy device; and
determining at least one characteristic of the electric energy device based on the at least one signal parameter.
